The adsorption control module 37 is electrically and signal-connected to the first intake valve 111, the first exhaust valve 121, the second intake valve 111', and the second exhaust valve 121', respectively. The controller module 31 inputs an adsorption start signal or an adsorption stop signal to the adsorption control module 37. The adsorption control module 37 is configured to control the first intake valve 111 and the first exhaust valve 121 to open upon receiving the adsorption start signal. The adsorption control module 37 is configured to control the first intake valve 111 and the first exhaust valve 121 to close upon receiving the adsorption stop signal, and then the adsorption control module 37 controls the second intake valve 111' and the second exhaust valve 121' to open.

When adsorption production is carried out in the first adsorption tank 1, the adsorption control module 37 controls the opening of the first air intake valve 111 and the first exhaust valve 121. When the concentration sensor monitoring module 32 detects that the concentration of organic solvent adsorption in the first adsorption tank 1 is a saturated value, the adsorption control module 37 controls the first air intake valve 111 and the first exhaust valve 121 to close, and then the adsorption control module 37 controls the second air intake valve 111' and the second exhaust valve 121' to open. In this cycle, the first adsorption tank 1 and the second adsorption tank 1' are alternately adsorbed, thereby improving the efficiency of the equipment.

A second cooling coil is provided within the second adsorption tank 1'. This second cooling coil forms a second cooling inlet and outlet 17' outside the second adsorption tank 1', and a second cooling pump 171' is provided at the second cooling inlet and outlet 17'. In this embodiment, the first and second cooling coils utilize the cooling coil structure and arrangement of conventional technology to cool the first adsorption layer 15 within the first adsorption tank 1 and the second adsorption layer 15' within the second adsorption tank 1'.

[0053] The control terminal 3 is provided with a cooling control module 38. The first cooling pump 171 and the second cooling pump 171' are respectively electrically and signal-connected to the cooling control module 38. The controller module 31 inputs a cooling start signal or a cooling stop signal to the cooling control module 38, which controls the activation or deactivation of the first cooling pump 171 or the second cooling pump 171'. The cooling control module 38 is electrically and signal-connected to the heat exchanger control module 33 via the controller module 31. The controller module 31 inputs a heat exchanger stop signal to the heat exchanger control module 33, and simultaneously inputs the cooling start signal to the cooling control module 38.

[0054] In this embodiment, a cooling control module 38 is provided to control the first cooling pump 171 and the second cooling pump 171' to start respectively to circulate cold water into the first cooling coil and the second cooling coil, thereby cooling the first adsorption layer in the first adsorption tank and the second adsorption layer in the second adsorption tank to room temperature, so as to meet the requirement that subsequent adsorption production can continue, thereby improving the efficiency of the equipment.
