In recent years, with the growth of the production and sales of liquid air separation plants, the market share has been increasing, but on the other hand, the overall technology of the equipment is poor, there are problems such as unattractive appearance, unclear and unclear logo, and unfriendly human-machine control interface. In order to further stabilise and develop the market and improve the recognition of the overall image of the liquid air separation plants, the industrial design of small ...

DEAR Air has a number of patented inventions, of which the "ultra-low discharge pressure and energy saving patent" is the leading one in China. The innovative five systems are mainly achieved by reducing the discharge pressure of the air compression system; reducing the resistance of the air cooling tower of the encounter cooling system, the adsorber of the purification system and the flow meter of the control system; upgrading the fractionation tower system by replacing the upper tower, the low...

1, air cooling tower and water cooling tower using Bauer ring packing to bear the air, waste nitrogen and cooling water heat transfer carrier, which has a large flux, low resistance, high separation efficiency, operating flexibility and other characteristics. In the water-cooled tower, it makes full use of the cooling capacity of the recycled waste nitrogen to reduce the temperature of the chilled water before it enters the chiller, reducing the electrical load of the chiller.2, large air separa...

Cryogenic liquid gasifiers such as liquid oxygen, liquid nitrogen and liquid argon are used in liquid gasification stations for direct gas supply or bottle filling. To ensure safe operation, set up safety control points and pay attention to the following matters.1) Set up low temperature control interlock points for cryogenic liquids out of the gasifier to control the gas outlet temperature at 5 to 30°C. When the outlet temperature is below 0℃, the liquid pump will be automatically cut off a...

The nitrogen water pre-cooler is a room temperature heat exchanger, installed outside the holding tank. It generally has two roles. One is to use the unsaturated degree of dirty nitrogen to cool the water, in the process air by water cooling, so that both the temperature of the air and the moisture content of the air can be reduced. The other role is in the air-cooled tower, the air and water contact, you can wash the air, to further remove the dust in the air and dissolve part of the impurities...

Centralised drainage design for the whole machine①For small air separation units and downhole equipment, a fixed and uniform centralised drainage outlet is designed on the skid block.②For large air separation units, the centralised drainage components are prefabricated in the workshop according to the design and taken away with the delivery, and then incorporated into the drainage line during installation on site according to the actual situation on the customer's side. Design of the operating ...

As the gas rises through the small holes to the upper plate, it always entrains the liquid from the lower plate. The oxygen content of the liquid on the upper plate is lower than that on the lower plate, so this phenomenon will offset some of the distillation effect. The amount of mist entrainment should not exceed 10%, more than that will damage the distillation process. Tower plate spacing and air velocity is the main factor affecting the fog froth entrainment. Operation of air separation equi...
