Technical Field

Background
The compressed air can carry a large amount of moisture after coming out from the air compressor, if the rear end needs to use the compressed air of low dew point, will generally use the dry compressed air of adsorption dryer.
The adsorption type dryers commonly used in the market at present are generally divided into two types, namely blowing heating regeneration and compression heat regeneration.
The air-blast heating regeneration adsorption dryer (air-blast heating dryer for short) heats the adsorbent by heating the ambient air, and has stable regeneration flow, low pressure and good regeneration effect, so the dryer has stable operation, low dew point (can be below 70 ℃ below zero), but higher energy consumption. The compression heat regeneration adsorption dryer (the compression heat dryer for short) heats and regenerates the adsorbent by utilizing the waste heat of the compressed air, so that the energy consumption is saved, the regeneration effect is poor due to the influence of the compressed air flow and the temperature, and the dew point quality and the stability are poor compared with those of an air blowing heat dryer. Under the great trend of energy conservation and emission reduction, more and more enterprises pay attention to the utilization of the waste heat of the compressed air, so that the compression heat dryer is more and more popular with the enterprises. However, with the development of air compressor technology, the outlet temperature of the compressed air is lower and lower, and the utilization amount of the compression heat is lower and lower, which brings challenges to the design of the compression heat dryer. Therefore, it is considered to combine the conventional air-blowing thermal dryer and the compression thermal dryer, and to develop a new type of dryer by utilizing their respective advantages.
In the prior art, the application number 201911386189.1 is CN110893309A, which discloses a compression heat drying device and a process applicable to large flow and low inlet air temperature, and the system has the following defects:

2. The technology utilizes blast heating for regeneration after the compression heat regeneration, and because the density of the compressed air is different from that of the ambient air, the speed of the compression heat regeneration is far faster than that of the blast heating regeneration, the regeneration time can be prolonged by utilizing the blast heating, and the heat loss is increased; in addition, in the blowing heating process, the temperature rise of the ambient air is completely realized by the heating of the heater, and the waste heat of the compressed air cannot be utilized, so that the energy consumption is increased, and the energy conservation is not facilitated.
3. The reaction capability of the technology is weak under extreme conditions, for example, after a fan fails, equipment can only be stopped for maintenance due to the fact that blast heating and blast cooling cannot be completed.
