The working principle of the invention is as follows: the exhaust gas first enters from the fifth inlet 261 and then flows into the inside of the outer case 25 through the exhaust gas diffusion member 26;
when the exhaust gas passes through the exhaust gas diffusion component 26, since the area ratio of the first port 361 to the fifth inlet 261 is greater than the area ratio of the second port 362 to the fifth outlet 262, and since the area ratio of the third port to the fifth inlet 261 is greater than the area ratio of the fourth port to the fifth outlet 262, the gas flow with higher middle density and strength can be guided to the peripheral region of the condensation component 221 through the first gas guide channel 36 and the second gas guide channel 37;
in addition, since the area ratio of the fifth port 381 to the fifth inlet 261 is equal to the area ratio of the sixth port 382 to the fifth outlet 262, and the area ratio of the seventh port to the fifth inlet 261 to the fifth outlet 262 is equal to the area ratio of the eighth port to the fifth outlet 262, the exhaust gas with moderate air flow intensity can be uniformly discharged through the third air guide passage 38 and the fourth air guide passage 39;

Then, the exhaust gas will be guided and dispersed by the exhaust gas diffusion plate 28, so as to pass through the condensation part 221 more uniformly, specifically, the second vent plate 22 can be rotated to the second rotation position, at this time, the limiting convex pillar 214 is in limiting contact with one end of the limiting groove 2211, the second through holes on the second vent plate 42 and the first through holes on the first vent plate 41 are distributed in a staggered manner, and the intersection area of the second through holes of the through hole ring group of the inner ring and the corresponding first through holes is smaller than the intersection area of the second through holes of the through hole ring group of the outer ring and the corresponding first through holes;
therefore, the waste gas in the middle area with higher airflow strength and density can be greatly blocked, so that the waste gas diffuses to the peripheral area, the waste gas can uniformly flow to the condensing part 221 through the waste gas diffusion plate 28, the target components in the air flow are condensed and liquefied through the condensing part 221, then the condensed and liquefied target components are discharged through a drain outlet and collected, and meanwhile, the residual gas after condensation and separation of the waste gas is discharged from the condensation gas outlet end 253;
then, the exhaust gas is exhausted to the second air inlet 254 through the flexible air pipe and the air guiding part 24 under the air suction effect of the fan assembly 23, and the exhaust gas gradually flows through the second channel formed by the flow guiding pipe 27 and is exhausted to the second rinsing tower 56 through the second air outlet 252;
wherein when waste gas flows through honeycomb duct 27, can be abundant carry out preliminary cooling to the waste gas that flows into first passageway initially, low temperature is by cyclic utilization, and the cooling is effectual.
On the other hand, before the exhaust gas is discharged into the second rinsing tower 56, the first valve 521 and the second valve 571 may be opened to make the first rinsing tower 51 and the second rinsing tower 56 contain the rinse liquid with a set volume, the first pump 54 and the second pump 5A may be opened according to the volume of the rinse liquid in the respective rinsing towers, and the fan assembly 23 may be opened while the pumps are opened to gradually input the condensed exhaust gas into the second rinsing tower 56;
wherein, since the third valve 5B1 is closed, the rinse liquid in the second rinsing tower 56 is increased, when the sum of the volumes of the rinse liquid in the first rinsing tower 51 and the second rinsing tower 56 reaches the set value, the first valve 521 is closed, and when the volume of the rinse liquid in the second rinsing tower 56 reaches the set value, the second valve 571 is closed;
when inputting the waste gas, the waste gas can pass through the rinsing liquid sprayed out by the second spraying pipe 59 for rinsing, then the waste gas of the primary rinsing can flow into the first rinsing tower 51 through the gas pipe 58, and the waste gas can be output through the second gas outlet 512 after passing through the rinsing liquid sprayed out by the first spraying pipe 53 for rinsing;
the flow can be controlled by adjusting the first valve 521, the second valve 571 and the third valve 5B1, so that the automatic circulation liquid change of the first rinsing tower 51 and the second rinsing tower 56 can be realized, and the set liquid levels can be always kept in the first rinsing tower 51 and the second rinsing tower 56;
in addition, the first valve 521, the second valve 571 and the third valve 5B1 may be closed at the same time, so that the first rinsing tower 51 realizes the spray cycle of the rinsing liquid through the first pump 54, the second rinsing tower 56 realizes the spray cycle of the rinsing liquid through the second pump 54, and after the cycle for a certain number of times, the rinsing liquids in the first rinsing tower 51 and the second rinsing tower 56 are gradually discharged by opening the second valve 571 and the third valve 5B 1;
when the volume of the rinse liquid in the first and second rinse towers 51 and 56 is too small to be supplied to the pump body for pumping out the rinse liquid, the third valve 5B1 is closed and the first valve 521 is opened, thereby performing the supply of new rinse liquid into the first and second rinse towers 51 and 56.
