Small garbage incineration tail gas treatment system and treatment technology thereof

Abstract

The invention discloses a small garbage incineration tail gas treatment system and a treatment technology thereof. The small garbage incineration tail gas treatment system is characterized in that a flue gas outlet of a garbage incinerator is connected with an inlet of a secondary combustion chamber; an outlet of the secondary combustion chamber is connected with an inlet of a quencher; an outlet of the quencher is connected with an inlet of a heat exchanger; after the heat exchanger preheats cold air, fresh air is blown into the incinerator through an induced draft fan; flue gas subjected to heat exchange enters an inlet of a dust remover; an outlet of the dust remover is connected with an inlet of an adsorber; an outlet of the adsorber is connected with inlets of deacidification towers; outlets of the deacidification towers are connected with an inlet of a demister; an outlet of the demister is connected with an inlet of a deodorizer; a biofilter and a chimney are connected and can be arranged in parallel; and after tail gas is purified through the biofilter, flue gas is finally discharged. According to the small garbage incineration tail gas treatment system, harmful flue gas generated during incineration can be deeply purified through a tail gas purification system, the purification efficiency is high, up-to-standard discharge can be achieved, and the small garbage incineration tail gas treatment system is quite suitable for being applied in small household garbage harmless treatment stations.

Description

technical field [0001] The invention relates to a tail gas treatment system, in particular to a small waste incineration tail gas treatment system. The invention also relates to the treatment process of the small waste incineration tail gas treatment system. Background technique [0002] At present, the problem of domestic waste in remote rural areas has become the most urgent environmental problem to be solved, and it is becoming more and more difficult to solve domestic waste. Most of the domestic garbage of the villagers is directly burned in the open air without any follow-up treatment, which seriously affects the environmental safety and the living environment of the residents. Toxic and harmful gases and a large amount of dust produced by garbage burning will seriously affect the quality of the surrounding environment. Especially dioxins, SO 2 The harm is even greater and will directly endanger the physical and mental health of the people. Therefore, it is particul...
