Coal conveying system of coal-fired power plant

Abstract

The invention provides a coal conveying system of a coal-fired power plant. According to the coal conveying system, a conveying line hidden on the ground and a conveying line perpendicular to the horizontal plane are adopted, so that the occupation of the ground space is reduced, the overall length is also shortened, and a large amount of land resources can be saved; and on the other hand, the conveying line hidden on the ground does not have the problems of coal dropping and coal floating so that the pollution to the environment of the power plant can be effectively reduced, and an image about landscape, cleanness and environment protection of the power plant can be improved.

Description

technical field [0001] The invention relates to the technical field of coal transportation, in particular to a coal transportation system of a coal-fired power plant. Background technique [0002] The coal handling system is one of the most common and important supporting systems in coal-fired power plants. In order to ensure and stabilize the coal demand of the power plant, the power plant will set up a coal yard with enough coal storage for a certain number of days to prevent the power plant from running During the period, frequent shutdowns occurred due to coal supply problems. [0003] The existing coal transportation system is generally composed of coal transportation lines, transfer stations, coal yards, and coal bunkers in the main factory building. After the coal is unloaded by wharf or trucks to the power plant, it first enters through the coal transportation lines and transfer stations. The coal is stored in the yard, and then falls from the coal yard through the ...

AI Technical Summary

Problems solved by technology

[0004] 1. The height of the coal bunker in the main workshop is related to the capacity of the steam turbine unit, usually between 20m and 40m, and the terrain of the wharf (dock unloading coal) and coal unloading ditch (vehicle unloading coal) is relatively low. Therefore, coal transportation The line needs to climb to a height of tens of meters to reach the top of the coal bunker from the wharf (dock unloading coal) or coal unloading ditch (vehicle unloading coal). Moreover, the climbing angle of the coal line cannot be too large, which will cause coal transport The span of the line is large and requires a lot of ground space;

[0005] 2. Although there is a closed steel plate on the coal conveying line to solve the problem of coal falling and floating coal, the problem of local coal scattering cannot be completely avoided due to the length of the coal conveying line is too long
