product description

The combined low dew point dryer is a low dew point drying equipment, which is a two-in-one unit of the freeze dryer and the adsorption dryer. The drier has the advantages of low air loss and low energy consumption, but has the limitation of the dew point temperature. The dryer has the advantages of low dew point and large loss of regeneration gas. The company developed a combination of low-dew point dryer is a combination of cold and dry machines and dryers of their respective advantages, through a reasonable pipe connection and capacity to maximize the advantages of both, to achieve the highest price.

working principle

Combination of low dew point dryer is the use of cooling and desiccant drying principle of PSA, a large number of water vapor condensation droplets discharged from the machine by the drainage in order to achieve the purpose of dry compressed air.

The combined low dew point dryer is a low dew point drying equipment, which is a two-in-one unit of the freeze dryer and the adsorption dryer. Low-temperature adsorption principle, low consumption, energy saving, intelligent operation, to meet the different needs of users.

Process flow

Compressed air first enters the preheater and has been drying the low-temperature compressed air exchange, reduce the temperature and then into the evaporator was further cooled to 2 ℃, at this temperature conditions, most of the gaseous water molecules have become liquid water is discharged, then the temperature The amount of compressed air into the suction tube is further dehumidified to obtain a lower dew point of the finished product gas, the lowest temperature of the dry compressed air into the heat exchanger, cooling high temperature wet air, while the temperature itself is also increased to prevent the output The condensation outside the pipeline, and after heating a small part of the role of compressed air regeneration tower, improve the regeneration efficiency and reduce energy consumption.
