The base 1 can move relative to the ground to facilitate the arrangement of the equipment at the tunneling face. The exhaust air processing module 2 is arranged on the base 1 and above the solution regeneration module 4. One end of the exhaust air processing module 2 is connected to the first air inlet 11, and the other end is connected to the first air outlet 12. The first air outlet 12 is connected to the air duct 61 arranged in the tunneling roadway through the transition air duct 62. The first fan 31 is arranged at the first air inlet 11 to generate air flow in the first air inlet 11, the exhaust air processing module 2, and the first air outlet 12 in sequence. The solution regeneration module 4 is arranged on the base 1. One end of the solution regeneration module 4 is connected to the second air inlet 13, and the other end is connected to the second air outlet 14. The second air outlet 14 is connected to the return air duct 63.

[0060] The exhaust air processing module 2 includes a first air box 21, an exhaust air processing wet curtain 22, a first liquid distributor 23, a dehumidification solution tank 24, and a first dust collection tray 25. The first air box 21 is arranged above the base 1. The opposite ends of the first air box 21 are connected to the first air inlet 11 and the first air outlet 12, respectively. The exhaust air processing wet curtain 22 is arranged in the first air box 21. The first liquid distributor 23 is arranged above the exhaust air processing wet curtain 22 in the first air box 21, and is used to spray solution to the exhaust air processing wet curtain 22. The dehumidification solution tank 24 is arranged below the exhaust air processing wet curtain 22 in the first air box 21, and the solution sprayed to the exhaust air processing wet curtain 22 falls into the dehumidification solution tank 24.

[0061] The solution used in the embodiment is one or a mixed solution of lithium bromide solution, lithium chloride solution, and calcium chloride solution, which can absorb water vapor in the air flow when the concentration is high.

[0062] The first liquid distributor 23 sprays the low-temperature concentrated solution to the spent-air treatment wet curtain 22. The spent-air flow entering the first air box 21 from the first air inlet 11 contacts the low-temperature concentrated solution on the spent-air treatment wet curtain 22, and the water vapor in the spent-air flow is absorbed by the solution and transferred to the solution.

[0064] The second liquid distributor 43 sprays the high-temperature dilute solution to the regeneration wet curtain 42. The spent-air flow entering from the second air inlet 13 contacts the high-temperature dilute solution on the regeneration wet curtain 42, and the water vapor evaporated from the high-temperature dilute solution is carried away by the air flow. The dust in the spent-air flow is adsorbed on the regeneration wet curtain 42 and is washed off by the solution sprayed by the second liquid distributor 43 to the regeneration wet curtain 42 and falls to the second dust collection tray 45. The solution sprayed by the second liquid distributor 43 to the regeneration wet curtain 42 finally falls to the regeneration solution tank 44. The dust in the spent-air flow is removed, and the spent-air flow finally passes through the second air outlet 14 and the return air duct 63 and is discharged along the top of the roadway, thereby improving the working environment of the roadway behind the tunneling working face.
