An air inlet pipe 103 is fixedly mounted on one side of one of the two connecting pipes 104, and an air outlet pipe 107 is fixedly mounted on the other side. Fixing brackets 105 are fixedly mounted on both sides of the upper end of the base plate 102, and one side of each fixing bracket 105 is fixedly connected to the drying tank 2. Both drying tanks 2 include a tank body 201. A first adsorption layer 202 is fixedly installed at the upper end of the interior of both tank bodies 201. A temperature sensor 203 is fixedly installed on the upper inner wall of one side of both tank bodies 201. A second adsorption layer 204 is fixedly installed at the middle position inside both tank bodies 201. A third adsorption layer 205 is fixedly installed at the lower end inside both tank bodies 201. The first adsorption layer 202 is a silica gel adsorption layer, the second adsorption layer 204 is a molecular sieve adsorption layer, and the third adsorption layer 205 is an activated alumina adsorption layer.

[0029] Specifically, in the dryer body 1, the casters 101 facilitate flexible movement of the dryer in different working environments. Pressure sensors and flow regulating valves are installed on the inlet pipe 103 and the outlet pipe 107, which can monitor the gas pressure and flow in real time and precisely control the gas flow according to actual needs. The fixed frame 105 can stably support the drying tank 2 and extend the service life of the equipment. In the drying tank 2, the temperature sensor 203 is electrically connected to the control box 106, which can transmit the real-time monitored temperature data in the tank to the control box 106.

[0030] Reference Figure 3 , Figure 4 The heating and regeneration mechanism 3 includes a heating box 304, a first fan 301 fixedly installed on one side inside the heating box 304, an electric heater 302 fixedly installed in the middle of the heating box 304, a first conveying pipe 303 fixedly installed at the upper end of the heating box 304, and a second conveying pipe 401 fixedly installed at the upper end of the cooling box 404. The cooling mechanism 4 includes a cooling box 404, a second fan 403 fixedly installed on one side inside the cooling box 404, and a cooler 402 fixedly installed in the middle of the cooling box 404. The first conveying pipe 303 and the second conveying pipe 401 are both fixedly connected to the drying tank 2 through pipes.

[0031] Specifically, in the heating regeneration mechanism 3 and the cooling mechanism 4, the first fan 301 and the second fan 403 are variable frequency fans, which can adjust the rotating speed according to the instruction of the control box 106, so as to control the flow rate of the heating and cooling gas.

The one-way valve is installed on the first conveying pipe 303 and the second conveying pipe 401, which prevents the backflow of the gas and ensures the normal operation of the whole system.

[0032] Working principle: the humid gas enters one of the drying tanks 2 from the gas inlet pipe 103, and sequentially passes through the first adsorption layer 202 (silica gel adsorption layer), the second adsorption layer 204 (molecular sieve adsorption layer) and the third adsorption layer 205 (activated alumina adsorption layer). Under the multi-layer adsorption, the water in the gas is fully adsorbed, and the dried gas is discharged from the gas outlet pipe 107. When the adsorbent in the drying tank 2 adsorbs water to a certain extent, the equipment switches the working state. At this time, the heating regeneration mechanism 3 starts, the first fan 301 sends the air into the heating box 304, the hot air heated by the electric heater 302 enters the drying tank 2 which needs to be regenerated through the first conveying pipe 303, and the adsorbent is heated to evaporate and desorb the water in the adsorbent. The high-temperature gas after desorption enters the cooling mechanism 4 through the second conveying pipe 401. In the refrigerating box 404, the second fan 403 blows the air to the refrigerating device 402, and the cooled gas cools the high-temperature desorption gas to condense the water vapor in it into liquid water. The cooled gas can be recycled for the next heating regeneration, and the other drying tank 2 performs the gas drying work at the same time. The two drying tanks 2 work alternately to realize the continuous and stable gas drying process. The whole process is intelligently controlled by the control box 106 according to the feedback data of the temperature sensor 203 and the pressure sensor, so as to ensure the efficient and stable operation of the equipment.
