Boiler slag and dust removing equipment

Abstract

Boiler slag and dust removing equipment comprises a boiler, a conveying plate and a slag storage chamber, wherein one end of the conveying plate is arranged on the lower part of a slag outlet of the boiler; a balance weight is arranged at the bottom of the other end of the conveying plate; a rotating shaft is arranged in the middle of the conveying plate; a high-pressure blast device is arranged under the balance weight; a dust removing tube is arranged on the upper part of the conveying plate; a one-way valve is arranged on the dust removing tube; the bottom end of the dust removing tube is connected with a dust hood; a conveying belt is arranged below the dust hood; the other end of the conveying belt is positioned above the storage chamber; and an impulse type cloth-bag dust collecting device is arranged at the upper end of the storage chamber. The boiler slag and dust removing equipment is reasonable in structural design; and slag is removed conveniently and quickly, raised dust is avoided effectively, running effect is good, manufacturing cost is low, and therefore, the boiler slag and dust removing equipment is easy to popularize and use on a large scale.

Description

technical field [0001] The invention relates to the field of power station auxiliary machines, in particular to boiler slag and dust removal equipment. Background technique [0002] At present, most domestic thermal power plants use mechanical boiler slag removal equipment. There are two types of mechanical slag removal equipment: one is solid-state slag removal equipment, the slag in the furnace is discharged after being solidified through the cold ash bucket or slag box at the bottom of the furnace, which is suitable for coal with a higher melting point of ash; the other is Liquid slag removal equipment, there is an insulated molten pool at the bottom of the furnace, and the molten slag flows out through the slag outlet or is discharged after being solidified by cold water, or blown with steam to form slag cotton and discharged. In the liquid slag removal equipment, the water-cooled wall near the burner is coated with refractory materials, and hot air powder feeding and h...

AI Technical Summary

Problems solved by technology

However, after the existing slag removal equipment is put into operation, its performance is extremely unstable, and frequent clogging of slag pipes and slag pumps forces the slag pump system to fail to operate normally and stably; when slag is dropped or transported on the conveyor belt, it is easy to cause Dust, resulting in poor site environment, the accumulation of dust is likely to affect the normal operation of slag removal equipment
