[0003] In the process of treating these waste gases, they are usually treated by filter plate purification and spraying, so that the purification liquid treats the gas:

[0004] However, simply using the spraying method to treat waste gas will result in incomplete waste gas treatment because the contact time between the waste gas and the purification liquid is too short. Some existing methods of treating waste gas by flushing waste gas into the purification liquid often result in incomplete treatment due to excessively large bubbles. Utility Model Content
