Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for a chemical reaction kettle. Background Art

[0002] A chemical reaction kettle is a device used to achieve single or multiphase physical or chemical reactions, and is usually used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation. During the use of a chemical reaction kettle, certain chemical waste gases will be generated. Directly discharging these waste gases into the air will have a negative impact on the environment and the physical health of personnel. Therefore, a waste gas treatment device is needed to purify them before discharging. There are various types of chemical reaction kettle waste gas treatment devices, and each device has its unique principle and scope of application. The commonly used water adsorption method at present is to spray water mist into the waste gas to help the solid particles in the waste gas settle.

[0003] A waste gas treatment device for a chemical reaction kettle disclosed in the publication number CN218553570U. Although this utility model can make the spraying head spray in the cylindrical tower through the setting of a water circulation component to neutralize the dust impurities and water-soluble harmful substances in the waste gas and concentrate them at the bottom end of the inner cavity of the cylindrical tower, and through the setting of a filter screen and through holes, the water can be circulated and sprayed to save water resources. Through the setting of a rotary spraying mechanism, the spraying range of the water mist can be expanded, and the absorption range of the waste gas can be improved, avoiding the waste gas passing through the water mist and improving the water treatment intensity, and the treatment effect is better.

[0004] However, the circulation component of this utility model mainly aims at recycling the used water for spraying to save water resources. The waste gas passes through the spraying mechanism and the filter screen for waste gas filtration, and the waste gas after single filtration is directly discharged. This single-stage filtration method is difficult to efficiently remove solid particles of all particle sizes, and there is a certain probability that the discharged waste gas will pollute the environment.
