Powder dust conveying method and system device for powder dust field

Abstract

The invention provides a powder dust conveying method and a system device for a powder dust field. The powder dust conveying method adopts remote paste pressurization and at least comprises the following steps: in the powder dust field, powder dust of the powder dust field is dispersed through high pressure water, the dispersed powder dust is formed into paste, and the paste powder dust is conveyed to an appointed paste storage site through a pipeline under the action of pressure. According to the invention, powder dust is made into paste directly in a powder dust storage field and then is conveyed to an appointed place through a pressure pipeline, so that the conveying cost of powder dust can be lowered greatly, and the adopted method is simple and reliable, is applicable to industrialized operation, and is a more ideal technical scheme for realizing powder dust conveying of the powder dust field at present; and particularly, the manner of excavating a groove is adopted, material is taken through a vertical plane by utilizing high pressure water, and then the material is made into paste to be conveyed, so that required equipment has the advantages of compactness in arrangement, simple structure and small occupied area.

Description

technical field [0001] The present invention belongs to a material conveying method and device, in particular to a long-distance conveying method and a system device for a fly ash field, which is mainly used for conveying fly ash in a fly ash field where the coal powder ash produced in the process of thermal power generation is accumulated. It can be used for powder ash transportation in other powder ash fields. Background technique [0002] At present, thermal power is still the largest source of electricity in my country, accounting for more than 70% of China's total installed capacity; thermal power mainly refers to the use of thermal coal for power generation, and the coal used in thermal power accounts for more than 50% of industrial coal . These coals will form coal ash after being burned by thermal power generation units. Since the coal used in current thermal power generation is processed coal powder, the coal ash formed after combustion also becomes powdery coal ash...

AI Technical Summary

Problems solved by technology

[0008] Through the above analysis, it can be seen that the existing fly ash transportation method has a lot of equipment, takes up a large area of ​​the site, requires a large amount of maintenance, and is prone to leakage due to the ash transportation bin pump. Defects that cause environmental pollution in the factory area, especially for the fly ash that has become an ash yard, the coal fly ash has formed a board, so it is difficult to use the above-mentioned transportation method for transportation, and further improvement is needed
