Double-valve dust discharge device for boiler smoke dust remover

Abstract

The invention discloses a double-valve dust discharge device for a boiler smoke dust remover. The device comprises an upper valve, a lower valve, a transitional dust bin, a maintaining window and sealing pieces. The upper end of the upper valve is connected with a dust bin of the dust remover, and the lower end of the upper valve is connected with the transitional dust bin; the upper end of the lower valve is connected with the transitional dust bin, and the lower end of the lower valve is connected with a dust discharge pipe of the dust remover; the maintaining window is arranged on the transitional dust bin; the sealing pieces achieve the seal between the valves and the dust bin of the dust remover and the transitional dust bin and the seal between the maintaining window and the transitional dust bin; and the maintaining window can be quickly opened or closed. The dust discharge device is simple and scientific in structure, is large in valve opening, and has no dust accumulating platform or dead corner; the dust discharge device is convenient and reliable in dust discharge, and leaks no air and does not influence normal operation of a boiler system; the dust discharge device is quick in maintenance; and in particular, the dust discharge device eliminates the problem of influence on operation caused by the blockage of a dust discharge valve due to dust accumulation and coking in one working period of the boiler. The dust discharge device is specifically suitable for being applied to biomass boiler smoke dust removing equipment.

Description

[technical field] [0001] The invention relates to an environment-friendly dedusting technology, in particular to a double-valve ash-discharging device for a boiler flue gas dust collector. [Background technique] [0002] At present, when traditional technology is used to solve the problem of boiler flue gas dust removal, because boiler flue gas, especially biomass (straw, tobacco stems, etc.), boiler flue gas contains a lot of dust and complex components, especially viscous substances such as tar , so it is easy to cause dust and coking at the dust discharge valve of the dust collector. In severe cases, it will lead to the failure of the dust collector and even the emergency shutdown of the boiler system, thus causing serious losses to production and life. [Content of the invention] [0003] The purpose of the present invention is to provide a dust removal device for boiler flue gas dedusting equipment with simple and scientific structure, reliable ash discharge, not easy ...
