Abstract

Freeze-drying equipment comprises a bearing device, an evaporator and a heat exchange device, wherein the evaporator and the heat exchange device are fixed on the bearing device. The bearing device isprovided with an air inlet buffer cavity and an air outlet buffer cavity, and is further provided with an air inlet connector and an air outlet connector. The evaporator is used for drying a compressed gas, and the evaporator comprises an air inlet and an air outlet which are respectively communicated with the air inlet buffer cavity and the air outlet buffer cavity, and a refrigerating medium iscirculated in an evaporator cooling pipe of the evaporator. The heat exchange device is vertically fixed on the bearing device and is used for cooling the refrigerating medium introduced into the evaporator, and the heat exchange device comprises a shell, a spiral tube and a metal wire mesh. The shell is provided with an inner cavity, and the inner cavity is provided with an inlet and an outlet for an external heat exchange medium to pass through. The spiral pipe is formed by winding a cooling pipe, an inner cavity is formed in the spiral pipe, and the cooling pipe is communicated with the evaporator cooling pipe, and can be used for cooling the refrigerating medium of the evaporator. The metal wire mesh is at least filled in a space formed by the spiral tube and the shell.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a freeze-drying device. Background technique [0002] Compressed air is an important power source in industrial manufacturing. Compressed air contains a lot of water. At present, moisture drying in compressed air mainly includes adsorption drying technology and freeze drying technology. The traditional freeze drying technology enters compressed air into the evaporator for drying. After heat exchange, the moisture in the compressed air condenses into liquid water after the temperature is lowered, and the moisture is filtered out of the machine through the water vapor separator, so as to achieve the purpose of drying. [0003] However, traditional evaporators are usually provided with copper tubes, and the refrigerant in the copper tubes is usually liquefied, cooled, filtered and decompressed by a refrigerant compressor, condenser, refrigerant filter and expansion valve. However, t...
