Description

Technical Field

[0001] This utility model relates to the field of wet dust removal mechanisms for waste gas treatment, and more specifically, to a wet dust removal mechanism for waste gas treatment. Background Technology

[0002] As people's living standards continue to improve, their requirements for the production and living environment are also increasing, and the disposal of household waste is becoming more and more common. A relatively complete treatment system and well-established operation have been formed for the treatment of urban household waste.

[0003] Currently, municipal solid waste is mainly treated through comprehensive utilization, sanitary landfill, pyrolysis, and composting to reduce volume, optimize resource utilization, and render it harmless. Among these methods, pyrolysis is the most commonly used technology for municipal solid waste treatment. Pyrolysis methods for municipal solid waste are divided into incineration and gasification. Incineration involves using an incinerator to perform high-temperature pyrolysis combustion of waste; this method is simple and relatively fast. Pyrolysis gasification uses a generator to oxidize, reduce, and pyrolyze the organic matter in the waste under anaerobic conditions. The heat energy from dry distillation breaks the chemical bonds of the organic matter, converting high molecular weight organic matter into low molecular weight CO, H2, CH4, tar, volatile gases, etc., to produce combustible gases. These combustible gases are then burned in a burner or purified before being used as fuel.

[0004] However, both incineration and gasification methods produce irritating exhaust gases containing dust. If these exhaust gases are discharged without purification, they will have a significant impact on the surrounding environment. Traditional exhaust gas dust removal devices can only handle the dust in the exhaust gas and are unlikely to remove harmful substances. Therefore, a dust removal device that can both remove dust and eliminate harmful substances in the exhaust gas is needed.

[0005] In the prior art, such as the utility model patent announcement number CN220047682U, a spray dust removal device for pyrolysis exhaust gas of municipal solid waste is disclosed. It includes a support, a spray cylinder shell, and a water tank. The spray cylinder shell is installed on the support. A smoke exhaust port is provided at the top of the spray cylinder shell, and a drain pipe is provided at the bottom of the spray cylinder shell. A drain valve is installed on the drain pipe. Upper and lower spray pipes are correspondingly arranged in the upper and lower parts of the spray cylinder shell, respectively. Both the upper and lower spray pipes are equipped with... Equipped with multiple downward-spraying nozzles, the spray cylinder shell below the lower spray pipe has an air inlet, the spray cylinder shell above the lower spray pipe has a packing layer, and the spray cylinder shell above the upper spray pipe has a demister. A water pump is installed in the water tank, and both the upper and lower spray pipes are connected to the water pump through extraction pipes. The water tank is connected to the drain pipe through a return pipe. This spray dust removal device can effectively separate particulate matter and eliminate gaseous pollutants in the exhaust gas, achieving compliant exhaust gas emissions.

[0006] In the aforementioned patent, dust removal is achieved through a double-layer spraying mechanism, and dust removal is only performed through double-layer spraying. However, when the flue gas flows, the spraying cylinder shell has a straight cylindrical structure, resulting in high flue gas flow and incomplete spraying, thus leading to incomplete exhaust gas spraying treatment.

By adopting a four-group treatment cylinder structure, which is connected to the treatment cylinder through a conduit, it can be used for slow and uniform flow of flue gas.
