[0031] Working principle:

[0032] First, the exhaust gas is passed into the washing chamber 110 from the air inlet pipe 109. When the exhaust gas passes through the perforated drawer 111, the activated carbon in the perforated drawer 111 absorbs harmful parts of the exhaust gas. When the activated carbon is saturated, the slider 126 is driven by the electric slide rail 118 to move, and the slider 126 drives the perforated drawer 111 to move out of the washing chamber 110 to replace the activated carbon in the perforated drawer 111.

[0033] Then, when the exhaust gas continues to rise, it is gathered by the gas gathering frame 112 and then flows into the upper side of the gas gathering frame 112 from the gas outlet 113. The water pump 102 draws the neutralizing agent from the water inlet pipe 120 to the connecting pipe 116 and then flows into the spray frame 115. Finally, the sprayer 121 sprays the exhaust gas in the form of mist to neutralize the acid or alkalinity of the exhaust gas flowing out of the gas outlet 113. The gas gathering frame 112 can improve the efficiency of neutralization.

[0034] Finally, the exhaust gas is discharged from the first air pipe 106 and detected by the detector 104. When the detector 104 detects that the exhaust gas meets the emission standard, the electromagnetic two-way valve 105 is controlled to connect the exhaust pipe 108 and the first air pipe 106, and the first air pipe 106 and the second air pipe 107 of the washing chamber 1 are closed, so that the exhaust gas is discharged from the exhaust pipe 108. When the detector 104 detects that the exhaust gas does not meet the standard, the electromagnetic two-way valve 105 is controlled to connect the first air pipe 106 and the second air pipe 107, and the first air pipe 106 and the exhaust pipe 108 are closed, so that the exhaust gas is passed from the second air pipe 107 into the air inlet pipe 109, and then enters the washing chamber 110 for washing again. The one-way valve 119 prevents the exhaust gas from flowing back.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
