Iii. Application of the chemical industry:
In chemical production, the nitrogen seal is used to ensure safe production and flammable and explosive, toxic and harmful gases. Nitrogen is mainly used in the production process of system replacement, emergency start of emergency, the nitrogen protection of hydrogen and hydrogen reaction device. The nitrogen protection device is applied in the production of chemical intermediates, which can effectively solve and reduce the explosion accidents, and the safety coefficient is greatly improved.
The method of extracting nitrogen is more, but it is mainly determined to take the way of the adsorption, and the air is separated. The feature is the device is simple, the operation is reliable, the cost is low, the quality is good. The pressure of the air compressor is reduced by cooling, filtration, and drying, and then the air storage tank is filled into the air tank, and the nitrogen unit is made from the storage tank, and the process of nitrogen is 99.95% of the finished product, and the whole process is controlled by PLC, which is controlled by PLC, adsorption, absorption, adsorption, adsorption, and retraction cycle.

In the case of sugar alcohol production, nitrogen is used in the production of sugar alcohol, which is used for the air source of the pneumatic valve of the hydrogen device and the hydrogenated reaction device, and the gas displacement of the device. Substitution of hydrogen compressor and nitrogen seal; The displacement of the device's air tightness test and reaction equipment; The gas displacement of the exhaust gas discharge and the gas replacement of the maintenance. The container is charged with nitrogen in the case of an accident; Finished sugar tank nitrogen seal preservation, anti-dyeing bacteria and anti-crystallization.
In the process of the production of sugar alcohol, the hydrogen device is supplied by the hydrogen device of 100 nm3-300nm3 each. Production is accompanied by a large amount of nitrogen, which is provided by nitrogen, such as 60,000 t/ years of sugar alcohol production devices, and the first drive requires nearly 30,000 nm3/d nitrogen, and the cost of foreign purchases is higher, and if there is a high cost of nitrogen, if it has a nitrogen device (cangasa), it can save a lot of money.
The application of the nt nitrogen protection device in the production of sugar alcohol is better solution to many of the problems in production, which can effectively prevent the explosion of human factors, and also have preventive measures and safety assurance for sudden accidents. At the same time, the gas source power of the hydrogen plant is saved, the safety level of the system is improved, and the stable operation of the valve is guaranteed, and the method of using nitrogen seal is also a kind of aggressive experiment that is worth reference to
The application of food preservation industry:
The food preservation cold chain USES nitrogen generator, mainly applied to fresh fruit, vegetables and meat food to keep fresh, can extend the shelf life and the incubation period of the food, this application is widely used abroad.
The food is frozen, especially the meat, after freezing, and the taste of the food is completely changed, and now people like to eat more fresh food, for meat, the seafood class is more so, if can guarantee the taste quality of the food is the same, can prolong the shelf life and the supplier of the food and the supplier of the food to increase the competition gap, and the food level nitrogen machine that we now produce is the demand that satisfies this industry user. It can be used in the warehouse, the nitrogen in the warehouse, or the direct nitrogen, convenience, light, and the use of the nitrogen purity can be reached 99.999%.
The application of the electronic industry:
Because lead is harmful to humans, preventing lead pollution has become a global trend. Japan began making lead-free manufacturing in the great public in 1998. Before 2003, Japan's SONY, Toshiba, Hitachi and nec had basically realized electronic products without lead. In 2003, the ministry of information and industry issued the "electronic information products pollution control and control administration" document, which, from July 1, 2006, completely banned the use of leaded welding materials in electronic information products, and asked for the electronic and electrical products of the market, including lead, mercury, cadmium, six value chromium, polybrominated diphenyl ether and benzyl six kinds of harmful substances. The trend of the market will force electronic products with lead solder to enter the market. Therefore, it is a pressing task for us to adopt lead-free welding technology in wave and return welding.

Non-lead electronics are becoming a big trend in the electronics industry, and companies see it as an effective means of improving competitiveness and expanding market share. However, the process of implementing this process is a system project, and in the process of lead production, there will be many unfamiliar application technology problems.
Lead-free welding environment refers to the environment of some of the decisive factors in the process of lead-free welding. In a more typical example, there is nitrogen protection in the process of backflow welding, lead-free wave soldering, lead-free chip level recovery. The technology of non-lead backreturn welding and lead-free wave soldering is relatively mature, and the competition between brands has been turned from technology to price and service, and the reason is that the production enterprises of many lead-free backflow and lead-free wave soldering are consistent in the technology of nitrogen protection.
The nitrogen is used in different purposes in the reflux environment, which can protect the surface of the board of PCB through multiple reflux, prevent the oxidation of the soldering disc and the bearing foot, and make the foot's infiltration better and the welding point is more bright. These are more significant in lead-free processes. Higher unleaded temperatures accelerated oxidation, and the welding spot of lead-free cream was in the 2171-221ºC, and some of them were as large as 26,0m, and the temperature was obviously greatly improved by the 183c melting point of the traditional low syncrete containing lead cream. Nitrogen will protect against oxidation. Although it is not necessary in lead-free processes, the use of nitrogen increases the process window (on the oven), and many non-lead-free producers are using it. Nitrogen can reduce surface oxidation and make the solder water better.
In addition, it is also critical for multiple welding skills. For example: in the welding of double plate, nitrogen protection has a large advantage in the multiple return process with osps, because the welding of the plate and the welding of the line is well protected under the protection of n2. Another benefit of using nitrogen is to increase surface tension, which makes the manufacturer more flexible in choosing devices (especially ultra-thin spacing device), and increases the surface of the solder's surface to make it easy to discolor.
The most popular nitrogen extraction method is to make nitrogen by changing pressure. Meet the personalized demand of the customer, the blue sky enterprise research and development of the nitrogen machine: the standard nitrogen quantity is 300 nm/h, the purity: 99.9%, the gas quality reaches the international standard, in the spirit of creating the idea of creative business value for the customer, providing the customer with the complete and excellent pre-sale, the sale, the after-sales service and the system solution. Technical characteristics of the reactive pressure adsorption system:
The nitrogen body is small, low consumption, large capacity and stable purity.
The 2.psa device is the cheapest way to get nitrogen, which is much lower than the price of nitrogen sold in the city, and the cost of production is much lower, and the cost of investment can be taken back in 10-24.
The microcomputer control, automatic unattended operation.
4. Easy maintenance, convenient replacement of spare parts.
5. create value, nitrogen 0.4 yuan to -0.6 per cubic meter.
The function of the psa transformer system is the system function of the nitrogen system:
Nitrogen purity on-line detection function
Display and regulating function of nitrogen flow
Nitrogen pressure display and regulating function
4. Unchecked nitrogen alarm function
The automatic displacement function of the nitrogen
The nitrogen is inactive for long periods of time
The carbon molecular sieve is much higher than nitrogen in the air, so by the control of the pneumatic valve, the two adsorption plates can be separated by alternating circulation, pressure adsorption, decompression removal, complete oxygen and nitrogen separation, the nitrogen that is separated by oxygen nitrogen, the nitrogen that is required, the equipment process and the storage are all low pressure gas, the risk of high pressure and the evaporation loss of the liquid.

6,The main application of nitrogen in beer preservation:
In this stage, nitrogen is used to protect the gas from the oxygen, and it can also be used to remove the bad volatiles of beer, such as ethyl and volatile sulfide, to improve the taste of beer, accelerate the maturity of beer, shorten the fermentation cycle, and then fill the wine with nitrogen in the fermentation tank.
2, the jar is ready for the pipe to be in the air, and the wine can be free in the jar, and when the beer enters the cleaning system from the filter system, the air in the tube or in the tank will flow into the beer and increase the amount of oxygen. In order to prevent this occurrence, it can be filled into nitrogen in the liquor jar system, and the discharge of the tank inside and inside the tube can greatly reduce the increase in the amount of oxygen in the wine jar, and also avoid the recovery of the amount of diacetyl in the process.
The effect of the packaging system on the amount of oxygen in beer is very large. In practice, if the air is used in the air, the amount of oxygen in the beer is greatly increased, and the inert gas (such as nitrogen) is used to make the pre-pressurized body. Top gas, top wine, filter
In the process of drinking, drinking, filtration and other beer, the pressure of nitrogen is prepared, and the pressure of nitrogen is the driving force of the liquid, which can make the beer as little as possible to reduce the solution oxygen, and keep the flavor quality and non-biological stability of the beer.
Nitrogen is a basic environmental material, which is a kind of inert gas that is colorless, chemical, inert, and occupies about 78% of the atmosphere of the sphere, and the gas nitrogen is used to keep the process of preservation without any chemical residue. In practical beer preservation application, the nitrogen purity theory should be 99.95%, and the actual application is 99.5%. Because of the effect of the ratio, 99.5% of the nitrogen machine should be calculated.

Nitrogen making machine Q and A
Why is the nitrogen machine not in stock?
All pressure containers are used for years of use, and the use of pressure containers is also required to be registered. The equipment of the spot, which indicates that the production inventory has been in place for a while, will affect the actual service life.
Why is your system of nitrogen more expensive than other people?
The system is made up of an air compressor, cold drier, filter, nitrogen, and buffer tank. The nitrogen machine is non-standard equipment, the air compressor of different brands, the cold drier, the tank and so on are different. Too cheap supporting equipment can also affect the overall service life.
A set of 500,000 devices will take five years and a set of 400,000 devices for five years.
Why is the amount of gas made of nitrogen and the effect of altitude?
The psa nitrogen machine is the principle of constant pressure adsorption, separating the nitrogen and oxygen in the air. The higher the altitude, the thinner the air, so the less nitrogen you extract from the air. So the nitrogen machine is related to altitude.
Which is more appropriate for the purchase of liquid nitrogen and purchase nitrogen?
The price of liquid nitrogen is related to the season, the general production season, the liquid nitrogen price is relatively expensive. (the off-season 600-800 tons, the peak season is 2500 tons, and the different regional differences are different.)
The psa nitrogen maker is a device and a power consumption. Specific requirements are calculated according to yield purity.
What are the criteria for the acceptance of nitrogen making machine?
The treatment of nitrogen machines was generally measured by nitrogen and nitrogen concentration, two relatively direct indicators.
How to maintain the late process of nitrogen production?
The daily maintenance of nitrogen making machine is simple:
(1) the air pressure machine should be maintained regularly, empty filter, oil, oil should be regularly called manufacturer replacement according to the instruction.
(2) the cold machine should check the cold media pressure regularly, and replenish it in time, and the heat sink will be cleaned by compressed air every day, and the filter filter will be replaced regularly, and it is 8000h. to see the situation, the pressure difference.
(3) open the air tank every day and drain the air with cold water.
(4) daily inspection of automatic drainers to avoid congestion and loss of water. When the valve is blocked, open the manual valve slightly, close the self-discharge valve and remove the automatic drainer and decompose it. When cleaning the automatic drain, clean the soap.
(5) the nitrogen machine master should check the work pressure, purity and flow of the adsorption tower.
