specific Embodiment 1

[0019] refer to figure 1 , the present embodiment 1 comprises hardening unloading coal plaza 1, and around unloading coal plaza 1, reinforced concrete pipe and coal particle collection well 6 are set, is connected with coal particle collection well 6 by reinforced concrete pipe and forms coal ditch 2, collects in coal particle The side of the well 6 is provided with a coal water drain 7, which is communicated with the coal particle collection well 6, and the coal particle collection well 6 and the coal water drain 7 at the position of the coal yard are arranged at a position aligned with the coal yard column 5, The coal water drain 7 is provided with a cover plate; the coal water ditch 2 formed by connecting the coal particle collection well 6 with the reinforced concrete pipe is connected with the coal particle sedimentation tank 3; the traditional coal water ditch is replaced by the reinforced concrete pipe connecting the coal particle collection well The coal-water collect...

specific Embodiment 2

[0022] The feature of this embodiment is that the cover plate of the coal water drain 7 is made of cast iron grille or a cover plate with the same structure and function as the grille, and other features are the same as those of the specific embodiment 1.

[0023] The working principle of the present invention is as follows:

[0024] After the coal truck has unloaded the coal, after cleaning the hardened coal unloading square, wash the hardened coal unloading square with water. Since the coal ditch 2 adopts reinforced concrete pipes, several coal particle collection wells 6 are arranged in the reinforced concrete pipes. A coal water drain 7 is arranged next to the coal particle collection well 6, and the washed sewage enters the coal water ditch 2 through the steel grid cover plate of the coal water drain 7, thereby avoiding the blockage of the coal water ditch pipeline; Then it flows into the coal particle sedimentation tank 3 through the coal water ditch 2 for purification, ...

Abstract

The invention relates to a coal-water collection system on the ground of a hardened coal unloading square in a coal-fired power plant. Ditch, next to the coal particle collection well, there is a coal water drain, which is connected to the coal particle collection well, and the coal particle collection well and coal water drain near the coal yard are set at a position aligned with the coal yard column. The coal water drain is equipped with a cover plate; the coal water ditch formed by connecting the coal particle collection well with the reinforced concrete pipe is connected with the coal particle sedimentation tank; it constitutes a coal-fired power plant where the reinforced concrete pipe connects the coal particle collection well to replace the traditional coal water ditch The coal water collection system on the ground of the hardened coal unloading square. The present invention replaces the traditional coal water ditch with the coal water ditch formed by the reinforced concrete pipe connected to the coal particle collection well, and has the beneficial effects of simple structure, reasonable layout, convenient cleaning and low cost.

Description

technical field [0001] The invention relates to a waste water collection system for a storage yard, in particular to a coal water collection system for hardening the ground of a coal unloading square in a coal-fired power plant. The utility model belongs to the technical field of supporting facilities of a thermal power plant. Background technique [0002] There is a coal unloading square near the coal yard. The coal truck transports the coal to the coal unloading square and then transports the coal to the coal storage yard for stacking. The coal yard of the coal-fired power plant needs daily washing, and the coal water (water Waste water mixed with coal) is collected by the coal ditch set around the coal yard and then led to the coal particle sedimentation tank near the coal yard (such as figure 2 shown). After the coal water is precipitated, the waste water is led to the waste water treatment system in the factory area for treatment. After the treatment reaches the stand...
