Drop dust conveying structure for slag of boiler of thermal power plant

Abstract

The invention discloses a drop dust conveying structure for slag of a boiler of a thermal power plant. The structure comprises a feeding frame and a storage box. A conveying belt is installed betweenthe feeding frame and the storage box. A plurality of plastic baffles are mounted on the conveying belt. A feeding hopper is installed on a top plate of the feeding frame, the bottom of the feeding hopper right faces the conveying belt, a speed reduction mechanism is arranged in the feeding hopper, and a water spraying pipe is arranged on the portion, close to the top plate, on the feeding frame.A scraper is installed between the inner walls of the storage box and is closely attached to the conveying belt. The slag is discharged from the interior of the boiler and enters the feeding hopper, the speed reduction mechanism decelerates the falling slag, and the slag slowly falls on the conveying belt, so that the situation that the slag impacts the conveying belt at a high speed and a lot ofdust splashes is avoided; the water spraying pipe sprays a small amount of water on the slag, so that the slag becomes wet, and the dust on the surface of the slag during conveying is prevented from being blown up by wind; and the plastic baffles protect the slag and prevent the slag from falling, the conveying belt carries the slag and conveys the slag into the storage box, the scraper scrapes the slag on the conveying belt, and then the slag is stored in the storage box.

Description

technical field [0001] The invention relates to the technical field of thermal power plant boilers, in particular to a dust-reducing conveying structure for thermal power plant boiler slag. Background technique [0002] Thermal power plants heat water through boilers to generate high-temperature steam, which drives steam turbines to generate power for power generation. Boilers often use coal as energy during use. After coal is burned, coal slag will remain, which is often called slag. After the slag is cooled, it needs to be transported and unified. Storage, the current transportation method is to directly release the cooled slag to the conveyor belt, and send it to the storage box for storage through the conveyor belt. The direct fall of the slag will easily arouse the fine dust, causing the dust to scatter and pollute the air. For this reason, we propose A dust-falling and conveying structure for boiler slag in a thermal power plant is used to solve the above problems. C...
