The excess sulfur dioxide passes through the filter 5, and the filter 5 filters and purifies it to avoid impurities in the sulfur dioxide, which affects the absorption efficiency. When the filter 5 filters and purifies, the impurities fall downward into the collection frame 7 under the action of its own gravity. When the test is completed, the staff can take out the collection frame 7 by driving the collection frame 7 to move upward along the inner wall of the groove 6, which is convenient for quickly cleaning the impurities and avoiding the problem of long-term accumulation of impurities and the generation of odor affecting environmental hygiene.

The liquid pump 18 then transports water from the containing box 13 to the water collecting frame 9 through the connecting pipe 10, and sprays it out in an atomized form, making the inside of the test box 2 humid. The sulfur dioxide gas introduced easily interacts with water to produce sulfuric acid and sulfurous acid, and some liquid adheres to the material.

[0035] Working principle: through the treatment cylinder 4, the solution in the treatment cylinder 4 absorbs the excess sulfur dioxide gas to produce sulfite, which reacts with other solutions to produce sulfur dioxide again, which is convenient for reuse, and at the same time avoids the residual sulfur dioxide flowing into the test box 2 to pollute the air, and the impurities on the filter 5 fall into the collection frame 7 under the action of its own gravity, and the collection frame 7 is detachable. Taking out the collection frame 7 is convenient for cleaning impurities, avoiding the long-term accumulation of impurities and the generation of odors that affect environmental hygiene. In addition, through the connecting plate 11 , a liquid pump 18, a containing box 13, a connecting pipe 10 and a water collecting frame 9 are used in combination, water can be sprayed out in atomization through the water collecting frame 9, thereby changing the humidity condition inside the test box 2, and the sulfur dioxide gas interacts with water to produce sulfuric acid and sulfurous acid.
