Household garbage gasification treatment system with chlorine removal function

Abstract

The invention relates to a household garbage gasification treatment system with a chlorine removal function. The system comprises a gasification furnace and a chlorine removing system, and is characterized in that the chlorine removing system comprises a fine chlorine filtering device and a coarse chlorine filtering device; the coarse chlorine filtering device comprises a plurality of filtering plates which are arranged in the gasification furnace from top to bottom; one end of each filtering plate is connected with the gasification furnace; the upward surface of each filtering plate inclinesdownwards from a fixed end to a free end; and the filtering plates in the gasification furnace are combined to form a filtering plate group. The household garbage gasification treatment system with achlorine removal function is characterized in that after combustible gas is generated in the gasification furnace, the combustible gas is directly and deeply dechlorinated, and high-temperature corrosion of the combustible gas to subsequent equipment is avoided, so that steam parameters and the power generation efficiency are improved, and reduction of low-temperature heterogeneous catalytic synthesis of dioxins in the flue gas cooling process is facilitated.

Description

technical field [0001] The invention relates to a domestic garbage gasification treatment system, in particular to a domestic garbage gasification treatment system with chlorine removal function. Background technique [0002] The treatment and disposal of domestic garbage and other wastes is a major problem that needs to be solved urgently in our country. Among them, the incineration power generation technology has the advantages of high degree of harmlessness, significant effect of volume and weight reduction, and energy recovery and utilization. It has been developed and applied relatively rapidly in recent years. However, the incineration process of domestic waste will inevitably produce secondary pollutants, especially chlorine-containing pollutants such as dioxin and hydrogen chloride (HCl), which will cause great harm to the environment and human health. On the one hand, the chlorine contained in domestic waste mainly forms HCl after incineration, and its content in wa...

Problems solved by technology

[0004] The present invention mainly solves the problems existing in the prior art that HCl can only be removed through a low-temperature tail gas purification device, which easily causes high-temperature corrosion of equipment, thereby limiting the steam parameters of waste incineration power generation, resulting in low power generation rate, and is easy to directly Or indirectly cause technical problems such as dioxin generation, etc., provide a direct deep dechlorination of combustible gas after the gasifier generates combustible gas, avoid high-temperature corrosion of subsequent equipment by combustible gas, thereby improving steam parameters and improving power generation efficiency, And help to reduce dioxins in the low-temperature heterogeneous catalytic synthesis of domestic waste gasification treatment system with chlorine removal function in the process of flue gas cooling
