According to the cooling mode of the condenser, the common cold dryers can be divided into air-cooled type and water-cooled type; according to the inlet temperature, it can be divided into high-temperature air inlet type (below 80 ℃) and normal temperature air inlet type (about 40 ℃); according to the working pressure, it can be divided into ordinary type (0.3-1.0mpa) and medium and high-pressure type (above 1.2MPa).

According to the cooling mode of the condenser, the common cold dryers can be divided into air-cooled type and water-cooled type; according to the inlet temperature, it can be divided into high-temperature air inlet type (below 80 ℃) and normal temperature air inlet type (about 40 ℃); according to the working pressure, it can be divided into ordinary type (0.3-1.0mpa) and medium and high-pressure type (above 1.2MPa). Working principle and process

The freezing type compressed air dryer can condense the water vapor in the compressed air into liquid drops by cooling, so as to reduce the moisture content. The condensed droplets are discharged from the dryer through the automatic drainage system. As long as the environment temperature of the downstream pipeline of the dryer outlet is not lower than the dew point temperature of the evaporator outlet, there will be no secondary condensation. Compressed air system

The purpose of the dryer is to dry the high-pressure gas, reduce the temperature of the high-pressure gas with the pressure of 30-32 bar and the temperature of 30 ℃ - 50 ℃ to 1-6 ℃, and filter out the moisture for the bottle blowing machine.

cooling water system

The cooling water is mainly used to cool the refrigerant, turning the gaseous refrigerant into liquid, and cooling water is cooled in the tower water machine.

Refrigerant system

With the low boiling point of refrigerant, the temperature of compressed air is absorbed from liquid state to gas state during heat exchange, so as to reduce the temperature of compressed air.

drainage system

The air is cooled by the precooler to remove part of the water, and then a large amount of water is removed by the evaporator. The condensed water is discharged to the trash separator through the water baffle or steam water separator, and then discharged through the drainer.

The main products of Hangzhou lino Machinery Co., Ltd. are: Standard (high temperature) freeze dryer, explosion-proof freeze dryer, non heat (micro heat) adsorption dryer, waste heat regeneration adsorption dryer, low dew point combined dryer: blast heat dryer, oil-water separator, precision filter, rear cooler, heat exchanger, gas tank. Mufflers and various specifications of filter elements, automatic drainer and other products, suitable for all kinds of air compressors, in order to remove water, oil, dust in the compressed air, so as to effectively and thoroughly solve the problems of low quality compressed air to users. Welcome new and old customers to inquire and purchase.
