Smoke processing device matched with household garbage incinerator

Abstract

The invention discloses a smoke processing device matched with a household garbage incinerator, and the device comprises a residual heat boiler heat energy recycling and temperature reducing device, a smoke desulfuration device, an active carbon adsorption device and a high-temperature cloth bag dust-removing device which are arranged sequentially from left to right, wherein the residual heat boiler heat energy recycling and temperature reducing device comprises a residual heat boiler and a deacidification tower; the residual boiler is provided with a smoke inlet and a smoke outlet; the smoke outlet is connected with a deacidification tower smoke inlet through a first smoke pipeline; the deacidification tower is provided with a deacidification tower smoke outlet; the high-temperature cloth bag dust-removing device is a cloth bag dust-removing device; the cloth bag dust-removing device is connected with the deacidification tower smoke outlet through a second flue; a pipeline connected with the deacidification tower smoke outlet is provided with an active carbon feeding device; the cloth bag dust-removing device comprises a plurality of dust-removing chambers which are connected in series; ash discharging buckets are arranged at the lower parts of the dust-removing chambers; ash discharging spiral machines are arranged at the lower parts of the ash discharging buckets; an evacuation flue is arranged at the upper part of the dust-removing device; and the cloth bag dust-removing device is provided with a cloth bag dust-removing device smoke discharging pipe.

Description

technical field [0001] The invention relates to a composition system for treating domestic waste incineration flue gas, which is a flue gas processing device used for processing urban domestic waste produced by an incinerator. Background technique [0002] The incineration of combustible waste is an important part of the comprehensive treatment of municipal solid waste. Currently, there are wet, dry and semi-dry methods for the flue gas treatment devices of incinerators used to incinerate waste. Among them, the semi-dry method has a better effect on flue gas treatment and is also mandatory in the current national standards. Due to the complex composition of domestic waste, which contains organic matter, plastic, rubber, metal, batteries and toxic and harmful materials, the flue gas after incineration contains a large amount of acid gases such as sulfur dioxide and hydrogen chloride, and is also prone to produce highly toxic substances such as dioxin. The flue gas treatment ...

Problems solved by technology

Due to the complex composition of domestic waste, which contains organic matter, plastic, rubber, metal, batteries and toxic and harmful materials, the flue gas after incineration contains a large amount of acid gases such as sulfur dioxide and hydrogen chloride, and is also prone to produce highly toxic substances such as dioxin. Flue gas treatment is very difficult, the investment in flue gas treatment equipment is large, the operating cost is high, and the failure rate is high
