Abstract

The invention discloses a combined pneumatic conveying system for coal ash in a coal-fired power plant. The combined pneumatic conveying system comprises a pneumatic dust collection sending system, atransferring system, a terminal ash unloading system and an ash ship-loading system, wherein the pneumatic dust collection sending system is connected with the transferring system through a first conveying pipe and a second conveying pipe, the transferring mechanism is connected with the ash ship-loading mechanism through a third conveying pipe, a fourth conveying pipe and a fifth conveying pipe,an air dispersing channel is formed between a first sleeve and a second sleeve, and the second sleeve is provided with a plurality of air dispersing holes in the axial direction. The invention furtherdiscloses an operating method. According to the combined pneumatic conveying system for the coal ash in the coal-fired power plant, the conveying pipes with an air dispersing function are used for combining the pneumatic dust collection sending system, the terminal ash unloading system and the ash ship-loading system into the conveying system which is not liable to ash clogging and low in maintenance cost; and the operating method can guarantee that material conveying units using the same conveying line will not convey materials at the same time, and the problem that the conveying line is overloaded will not occur.

Description

technical field [0001] The invention relates to a coal-fired power station fly ash combined pneumatic conveying system and an operating method thereof, belonging to the technical field of material conveying. Background technique [0002] With the improvement of economic level, the development of industrial technology is getting faster and faster. Pneumatic conveying plays an important role in industrial growth. Pneumatic conveying is the ability to use airflow to transport granular materials along the direction of airflow in a closed pipeline, which is a fluid state. A specific application of chemical technology. With the continuous improvement of production scale, the requirements for conveying distance are getting higher and higher, but with the growth of pipelines and the increase of height difference, the difficulty of conveying is also increasing. If the length exceeds a certain length, the material conveying pipeline will often Long ash plugs appear, causing pipe bloc...
