Deduster

Abstract

The invention provides a deduster composed of two components, which are a dust particle and flue gas separating apparatus and a dust discharging apparatus. The dust particle and flue gas separating apparatus comprises a cyclone generator 1 arranged above a built-in cylinder-shaped electrode. The middle part of the cyclone generator 1 is a support, and the peripheral of the cyclone generator 1 is fixed on the wall of an electric dedusting apparatus. A heat insulating layer 8 is arranged on the wall of the electric dedusting apparatus, wherein the heat insulating layer 8 is used for holding temperature. A space between a cylinder wall contacting an edge of a dust inhibitor 3 and a wall of the electric dedusting apparatus is provided with a jacket 7. The dust discharging apparatus is mainly composed of a dust collecting hopper 11, a dust filter 12, a back flushing apparatus 15, a water cooler 17, a dust discharging blower 13, and the like. The dust discharging apparatus is positioned at a lower part of the dust particle and flue gas separating apparatus, and is used for discharging separated dust. With the deduster with the structure, advantages of cyclone centrifugal dedusting and electric dedusting can be combined, and dust particles can be effectively separated from flue gas, such that a dedusting effect is reached. The pollution to the atmosphere is reduced, and the purified flue gas can be recycled. Therefore, an environment protection effect can be reached, electricity consumption can be reduced, and energy can be saved.

Description

technical field [0001] The invention relates to a dust remover, in particular to an electric dust remover device in an incineration system. Background technique [0002] In the traditional incineration system, natural gas fuel is used as raw material to provide a heat source to completely incinerate and crack the tail gas rich in toxic gases in the incinerator to reduce the hazards of toxic and harmful gases in the tail gas. The generated flue gas contains a large amount of dust particles. If the flue gas is not dedusted, the incinerated flue gas will contain a small amount of dust. If the incineration tail gas is reused in the curing furnace, the flue gas containing dust particles will be directly recycled to the curing furnace for coloring. When the paint of the coated board is cured, the dust particles contained in the gas will seriously affect the quality of the surface coating of the board, which is not conducive to the production of high-quality color-coated boards.
