the second step is as follows: simultaneously starting the hot air blower 8 to operate, discharging hot air into the activated carbon fiber adsorption-desorption tower 2 through the air discharge pipe 9, increasing the temperature in the activated carbon fiber adsorption-desorption tower 2, closing the first electromagnetic valve 11, the first air suction pump 4 and the hot air blower 8 after the temperature is increased, opening the second electromagnetic valve on the second exhaust pipe 14, and then starting the vacuum pump 12 to operate, because the temperature in the activated carbon fiber adsorption-desorption tower 2 is higher, and the adsorption capacity of the activated carbon fiber is reduced along with the increase of the temperature, when the temperature in the activated carbon fiber adsorption-desorption tower 2 is increased, more adsorbed components can be desorbed, and the desorbed components are discharged into the condensation tank 3 under the cooperation of the vacuum pump 12, the second air suction pipe 13 and the second exhaust pipe 14, and then starting the condenser 18 and the exhaust fan 15 to operate, the cold air produced by the condenser 18 is pumped out through the third air pumping pipe 17, the cold air and the methyl bromide are condensed in the condensing box 3 discharged through the third exhaust pipe 16, the second air pumping pump 19 is started to operate in the condensing process, the condensed methyl bromide is pumped out through the air pumping pipe 20, and then the methyl bromide is discharged into the fumigation chamber 1 through the exhaust pipe 21, so that the purpose of recycling is achieved;
the third step: when the activated carbon adsorption fiber plate 7 needs to be replaced, a sealing door on the activated carbon fiber adsorption-desorption tower 2 is opened, the activated carbon adsorption fiber plate 7 is pulled by hand to move, the activated carbon adsorption fiber plate 7 drives the connecting block 22 to move, and the arc-shaped limiting block 23 is in extrusion contact with the inner wall of the arc-shaped limiting groove, so that the arc-shaped limiting block 23 extrudes the compression spring 24 to move downwards, the arc-shaped limiting block 23 is separated from the arc-shaped limiting groove, the connecting block 22 is separated from the sliding groove, and the activated carbon adsorption fiber plate 7 is taken out of the activated carbon fiber adsorption-desorption tower 2 to be replaced, and the limiting rod plays a limiting role, so that the arc-shaped limiting block 23 is prevented from being deviated in the moving process.
