Pneumatic ash conveying pipeline for thermal power plant

Abstract

The pneumatic ash conveying pipeline comprises a pipeline body, the pipeline body comprises a horizontal pipeline body and a vertical pipeline body, the horizontal pipeline body and the vertical pipeline body are connected through an inner cavity corner, a rotating shaft is fixedly connected to the inner cavity corner of the pipeline body, and a reciprocating lead screw is fixedly connected to the left side of an inner cavity of the horizontal pipeline body of the pipeline body; the side wall of the rotating shaft is rotationally connected with an anti-blocking assembly, a buffering assembly is arranged in the anti-blocking assembly, the end of the reciprocating lead screw is connected with a scraping assembly, and the scraping assembly is used for cleaning dust attached to the inner wall of the pipeline body. The dust accumulation phenomenon is avoided, the impact of airflow on the inner wall of the pipeline body can be effectively reduced, the abrasion degree of the inner wall of the pipeline body is reduced, and the durability of the pipeline body is improved.

Description

technical field [0001] The invention belongs to the technical field of ash conveying pipelines, in particular to a pneumatic ash conveying pipeline in thermal power plants. Background technique [0002] Pneumatic ash conveying, also known as air conveying, utilizes the energy of air flow to convey granular materials in the direction of air flow in a closed pipeline, which is a specific application of fluidization technology. At present, in the daily production of thermal power plants, the fly ash produced by combustion is mainly collected by electrostatic precipitator and bag dust collector, and then transported to the dry ash warehouse through the pneumatic ash conveying system for comprehensive utilization. However, during the conveying process, failures such as pipe blockage frequently occurred, affecting the safe and stable operation of the unit. [0003] At present, the existing pneumatic ash conveying pipelines of thermal power plants have a single structure and singl...

However, during the transportation process, there are frequent failures such as pipe blockage, which affects the safe and stable operation of the unit

[0003] At present, the existing pneumatic ash conveying pipelines in thermal power plants have a single structure and a single function, which is not convenient for self-cleaning of the inner wall of the pipeline, which is likely to cause pipeline blockage, and the cleaning of the staff is time-consuming and laborious, and the work efficiency is low, which cannot meet the needs of use
