Abstract

The invention provides a high-temperature pyrolysis gasification treatment system and process for household garbage. The high-temperature pyrolysis gasification treatment system for household garbageinvolves a shaftless spiral drying conveyor, a high-temperature pyrolysis gasifier, a water-gas heat exchanger, a cyclone dust collector and a series of equipment; the high-temperature pyrolysis gasification treatment process for household garbage comprises following five steps of garbage drying and feeding, garbage high-temperature pyrolysis and gasification combustion, high-temperature tail gasrapid cooling treatment, tail gas purification treatment, solid waste and liquid waste treatment and the like. According to the system and the process, equipment selection and technological process design is reasonable, garbage feeding control is accurate, drying effect is good, the high-temperature pyrolysis gasification combustion temperature of the garbage is high, the high-temperature pyrolysis gasification combustion time is long, various toxic and harmful gases such as dioxin can be effectively decomposed, the high-temperature tail gas is subjected to rapid cooling treatment, so that thedioxin is prevented from being synthesized again; and when the tail gas is purified, various dust, water vapor and toxic and harmful substances in the tail gas can be absorbed and subjected to harmless treatment in a targeted manner, so that zero pollution discharge of tail gas can be realized.

Description

technical field

[0001] The invention relates to a solid waste treatment system, in particular to a domestic waste high-temperature pyrolysis gasification treatment system and process, belonging to the technical field of waste treatment equipment and processes. Background technique

[0002] With the improvement of environmental protection requirements, the current treatment of domestic waste is mainly based on high-temperature pyrolysis and gasification. Garbage pyrolysis and gasification refers to the burning of waste under anaerobic or hypoxic conditions. The organic units in the waste The process in which the broken macromolecules produce small molecule gas, tar and residue. Garbage pyrolysis gasification technology not only realizes the harmlessness, reduction and recycling of garbage, but also effectively overcomes the problem of dioxin pollution caused by garbage incineration. To realize the pyrolysis gasification combustion of domestic waste, it is necessary to be equ...
