In particular, chemical plants, spraying industries, pharmaceutical factories, coking plants and refineries, etc., emit waste gas with a strong odor, seriously polluting the environment and affecting human health. Industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without being treated to meet the standards, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Publication number: CN207680316U discloses a waste gas treatment device that fully treats waste gas, including a cylinder, legs are fixedly installed on both sides of the bottom surface of the cylinder, and the top and bottom of the inner cavity of the cylinder are respectively fixedly mounted with a filter screen and a circular plate, and a motor is fixedly installed in the middle of the bottom surface of the cylinder. The output shaft of the motor passes through the cylinder, the circular plate and the filter screen in sequence and extends to the top of the inner cavity of the cylinder. A stirring blade is fixedly installed on the output shaft of the motor. The exhaust gas treatment device that fully treats the exhaust gas, through the cooperation of the air inlet pipe, the hole ball and the one-way air inlet valve, under the action of the hole ball, the gas is dispersed into the cylinder through the holes on the ball hole, so that the contact area between the exhaust gas and the treatment liquid in the cylinder is larger, and the treatment liquid is stirred with the cooperation of the motor and the stirring blades. The gas will not be wrapped in the treatment liquid due to the generation of bubbles, thereby achieving the effect of thorough treatment. However, the above technology only treats the exhaust gas internally when treating the exhaust gas. During the operation of the device, the treated gas is discharged from the outlet. The inner wall at the outlet position is prone to adhere to a large amount of waste slag particles, which in turn affects the effect of exhaust gas treatment. Therefore, it needs to be improved.

[0026] Working principle: When the exhaust gas treatment device is used, the exhaust gas enters the interior of the earphone treatment box through the air inlet pipe 5, and then the exhaust gas rises upward, passes through the filter 8 to adsorb and filter the particulate matter contained in the exhaust gas, and the filtered exhaust gas enters the tertiary treatment box 3. At this time, the external liquid is sprayed on the interior of the exhaust gas treatment device through the spray pipe 11, so that the harmful substances in the filtered exhaust gas can be neutralized, and then the waste liquid drips downward and falls into the interior of the treatment box. By setting up the guide table 16, the dripping waste liquid can be conveniently collected and enter the collection box 17. The personnel can collect the collected waste liquid through the handle 18. The waste gas after filtering and neutralization enters the interior of the four-stage treatment box 4. At this time, the moisture in the treated waste gas can be adsorbed through the adsorption layer 14. Under the action of the fan 15, the treated waste gas passes through the conical cover 6 and enters the exhaust pipe 7.
