Three-in-one plate exchange type refrigeration dryer and work method

Abstract

The present invention relates to a three-in-one stainless steel plate exchange type refrigeration dryer and a work method. According to the three-in-one stainless steel plate exchange type refrigeration dryer, on one end, compressed air enters a three-in-one stainless steel plate type heat exchanger, is subjected to heat exchange cooling, and then is subjected to separation water-removing through a plate exchange built-in type silk screen, and the outlet is connected with the customer backend pipeline; and on the other end, the heat exchanger refrigeration system evaporator outlet is communicated with the refrigeration compressor inlet through a pipeline, the refrigeration compressor outlet is communicated with the condenser inlet through a pipeline, the condenser outlet is communicated with the drying filter inlet through a pipeline, the drying filter outlet is respectively communicated with the capillary inlet and the high-low voltage controller through pipelines, the capillary outlet is communicated with the three-in-one stainless steel plate type heat exchanger evaporator inlet, one end of the electrical control is connected with the compressor, the other end is connected with the high-low voltage controller and the condenser fan, and the electrical control is used for controlling the works of the compressor, the high-low voltage controller and the condenser fan so as to improve the heat exchange efficiency, such that the compressed air can enter the evaporator at the low temperature so as to reduce the load of the refrigeration system.

Description

technical field [0001] The invention relates to a three-in-one plate exchange type cold dryer used for dewatering and built-in screen separation of a frozen cold dryer and a working method, belonging to the field of cold dryer manufacturing. Background technique [0002] 1. CN103344135A, name "Plate Evaporative Condenser", including a shell and a water collection tank, an axial flow fan is installed on the upper end of the shell, and a water baffle is installed inside the shell. It is characterized in that: a At least two guiding baffles with air guiding function, the root of the guiding baffles are connected with the inner wall of the housing, and there is a wind and water deflection opening between the suspended end of the guiding baffles and the inner wall of the housing; two adjacent guiding baffles The wind and water baffles are located on opposite sides of the shell; a set of tube-plate groups as plate radiators are arranged between two adjacent guide partitions and in...

AI Technical Summary

Problems solved by technology

Its shortcomings: First, the separation device basically adopts the baffle type separation device, and needs to be equipped with a large number of heavy pipelines, and the separation effect of the baffle type separation is affected by the stable processing capacity, and it is difficult to adapt to the changing customer environment The second is that the shell-and-tube shell is made of carbon steel, which has been in contact with humid air for a long time, and the rust phenomenon is very serious, which will pollute the air twice; the third is that the internal heat exchange tubes are made of copper tubes, which will produce patina after a long time. The heat exchange efficiency of the fin type is not very high; therefore, the volume of the shell-and-tube heat exchanger is relatively large, and the corresponding overall equipment is also large in size and high in cost.
