[0002] In the process of industrial production, a large amount of waste gas will be generated. There are a large number of harmful substances in the waste gas, which poses a great threat to the health of workers and also brings great environmental pollution problems. With the development of society, people use purification equipment for exhaust gas during industrial processing to ensure that the exhaust gas does not pollute the environment.

[0003] Among them, a high-efficiency, energy-saving and environmentally friendly exhaust gas treatment device for a combustion boiler disclosed in application number CN202220528249.X is also an increasingly mature technology. The high-efficiency, energy-saving and environmentally friendly exhaust gas treatment device for a combustion boiler, the cooperation of filter box one, escape pipe, shower box, nozzle, output pipe and filter box two, enables the exhaust gas to be in contact with water for multiple times, thereby improving the purification effect. Moreover, the cooperation of exhaust pipe one and filter box one enables the treatment device to preliminarily purify the fine dust and acidic gas in the exhaust gas, and the setting of the escape pipe can further enhance the purification effect of the fine dust, and the alkaline solution sprayed by the nozzle forms water mist in the shower box, which can make the acidic gas and the alkaline solution fully contact, and finally, the secondary purified gas is dispersed into multiple small airflows through exhaust pipe two to contact the filtrate in filter box two, so that the gas and liquid are in full contact, and effective purification of fine dust and acidic gas is achieved. At the same time, through the cooperation of motor one and stirring blades, the uniformity of the filtrate can be ensured, thereby improving the filtration effect of the filtrate.

[0004] Based on this, we agree with the advantages of the above products, but there are still the following defects:
