Liquid nitrogen machineMain applications:

1. Superconducting technology

The unique characteristics of superconductors make it possible for them to be widely used in various fields. The use of liquid nitrogen instead of liquid helium as a superconducting refrigerant to obtain superconductors has led to the large-scale development and application of superconducting technology, which is considered one of the greatest scientific discoveries of the 20th century.

2. Manufacturing and Testing of Electronic Components

Liquid nitrogen is a faster and more useful method for shielding and inspecting electronic components and circuit boards.

3. Low temperature ball milling technology

The low-temperature planetary ball mill continuously inputs liquid nitrogen gas into a planetary ball mill equipped with an insulation cover. These cool gases absorb the heat generated by the high-speed rotating ball mill tank in a timely manner, keeping the ball mill tank containing materials and grinding balls in a certain low-temperature environment. Mixing, fine grinding, new product development, and small-scale production of materials in low-temperature environmentsThe equipment. This product has a small volume, comprehensive functions, high efficiency, and low noise. It is widely used in pharmaceuticals, chemicals, environmental protection, light industry, building materials, metallurgy, ceramics, mineral deposits, and other fields.

Liquid nitrogen refers to liquid nitrogen gas. Liquid nitrogen is a lazy, colorless, odorless, non corrosive, non flammable, and extremely low-temperature liquid that absorbs a large amount of heat and can cause frostbite when touched during vaporization. Nitrogen makes up the majority of the atmosphere (78.03% by volume and 75.5% by volume). At normal pressure, the boiling point of nitrogen is -196.56 ℃, and 1 cubic meter of liquid nitrogen can swell to 696 cubic meters of pure gaseous nitrogen (21 ℃). If pressurized, liquid nitrogen can be obtained at higher temperatures.

In industry, liquid nitrogen is obtained by fractional distillation of air. First, purify the air and then liquefy it in a pressurized and cooled environment, separated by the different boiling points of each component in the air. It is not a problem for human skin to directly touch liquid nitrogen instantly, and frostbite will only occur after 2 seconds and is irreversible

During the use of liquid nitrogen machines, it is important to note that the ambient temperature should not be too high. Generally, it is recommended that the ambient temperature be between 0-30 degrees Celsius.

The usage method is very simple. A nitrogen system and a liquid nitrogen system can be matched with a Doova tank according to actual usage needs. When starting up, first turn on the nitrogen system and then turn on the liquid nitrogen system. The first startup can produce liquid nitrogen in about 40-50 minutes, as the cooling time is longer. If it is turned on the next day, liquid nitrogen can be produced in about 25-30 minutes.

The liquid nitrogen machine is primarily used in scientific research and teaching, animal husbandry freezing and precision storage, medical operations, high machinery manufacturing, and other low-temperature research fields. It can provide small liquid nitrogen equipment to meet the different requirements of different industries and users for liquid nitrogen use, satisfying the needs of different users.

The equipment is based on the principle of pressure swing adsorption, using high-quality carbon molecular sieves as adsorbents to produce nitrogen from air under a certain pressure. By purifying dry compressed air, pressurized adsorption and depressurized desorption are carried out in the adsorber. Due to dynamic effects, the diffusion rate of oxygen in the micropores of carbon molecular sieves is much higher than that of nitrogen. When adsorption reaches equilibrium, nitrogen is enriched in the gas phase, forming finished nitrogen gas. Then the pressure is reduced to atmospheric pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities, completing the regeneration.

Generally, two adsorption towers are set up in the system, one tower for nitrogen adsorption and the other tower for desorption and regenerationPLCThe program automatically controls the alternating cycle operation of the two towers, performing oxygen and nitrogen adsorption and separation, and then obtaining qualified nitrogen gas, which enters the air-cooled oil-free circulation compressor and liquefaction equipment to transform the nitrogen gas from gas to liquid, obtaining liquid nitrogen.

The main method of collecting liquid nitrogen is through liquid nitrogen tanks. Double layered stainless steel can better achieve insulation while reducing evaporation, and the wheels that are easy to move can be easily pushed even when fully loaded. According to user needs, a liquid level gauge display can be equipped to keep track of the liquid nitrogen capacity in the tank at any time.

According to different needs, there are also biological tanks that can freeze specimens, and various options can be contacted by our company.
