Automatic deashing device for thermal-powered or thermoelectric boilers

Abstract

An automatic deashing device for thermal-powered or thermoelectric boilers sequentially comprises an air source and a gas source, an air path and a gas path, energy starters, a main and branch converter, energy temporary storage units and a pipeline unit. The air source and the gas source, the air path and the gas path, the energy starters, the main and branch converter and the energy temporary storage units are connected by the pipeline unit, and guide pipes are connected with output ends of the energy temporary storage units. The automatic deashing device is characterized in that the pipeline unit comprises multiple pipelines with different parameters, parameters of the pipelines are matched with corresponding parameters of corresponding energy temporary storage units, so that minimum detonation energy loss is achieved, shape and intensity distribution of airflow are adjusted, and firing range of the airflow is improved; further, the parameters include shape, size, wall thickness, cross-sectional area and volume, the external diameters of the pipelines between the air source and the energy starters range from 12 mm(millimeter) to 210 mm, and the external diameters of the pipelines between the gas source and the energy starters range from 7mm to 166mm.

Description

technical field [0001] The invention relates to an automatic ash cleaning device for thermal power generation or thermal power boilers, in particular to an automatic ash cleaning system for boiler flues in power plants and thermal power plants. Background technique [0002] The existing technology only has direct pipeline connections for the basic functional components, that is, the air source and the energy starter, and the energy starter and the energy temporary storage. Cooperating with functional components and pipelines, the technical effect is very poor. The effective range of the radiated shock wave and airflow is very short, only about 3m, which is far from satisfying the soot blowing effect of large and medium-sized boilers, especially for the internal boiler. Dead angle, leeward side, long-distance dust accumulation can't be solved, the radiation shape of the shock wave airflow can't be adjusted, and the intensity decays quickly, etc. For example, the size of the ...

[0002] The existing technology only has direct pipeline connections for the basic functional components, that is, the air source and the energy starter, and the energy starter and the energy temporary storage. Cooperating with functional components and pipelines, the technical effect is very poor. The effective range of the radiated shock wave and airflow is very short, only about 3m, which is far from satisfying the soot blowing effect of large and medium-sized boilers, especially for the internal boiler. Dead angle, leeward side, long-distance dust accumulation can't be solved, the radiation shape of the shock wave airflow can't be adjusted, and the intensity decays quickly, etc.

For example, the size of the intake pipe and the guide pipe are matched with each other, the connection of multi-stage pipelines is coordinated with each other, and the cooperation between the inlet and outlet pipelines and the energy converter, as well as the overall coordination of further regional component pipelines, and the entire pipeline of the entire system The cooperation with functional components does not give full play to the advantages of local cooperation and overall cooperation
