Problems solved by technology

[0002] The landfill leachate from the waste incineration plant has been separated by the grid in the waste pit, and still contains a large amount of fine fiber matter. If it is not removed before entering the adjustment tank, it will seriously affect the normal operation of the subsequent treatment process
[0003] Adding grids is a common solution. The grids can be divided into artificial grids and mechanical grids. Mechanical grids have high manufacturing requirements, occupy a large area, and have a high failure rate. Biogas will be generated in the leachate adjustment tank. Use Mechanical grills have a high risk factor
Artificial grilles have relatively low manufacturing requirements, small footprint, low failure rate, and low risk factor, but labor intensity is high and sanitary conditions are poor

Embodiment Construction

[0012] Such as figure 1 As shown, the present invention includes a box body 1 and a box cover 2 connected to the upper end of the box body 1, and opening the box cover 2 just allows maintenance and thorough cleaning of the inside of the box body.

[0013] The box 1 is provided with an obliquely arranged screen 3 to divide the box 1 into an upper cavity 4 and a lower cavity 5. The screen 3 is made of 304 stainless steel, and the inclination angle of the screen 3 is a, a=30° , The mesh number of screen cloth 3 is 7 meshes.

[0014] The screen 3 is supported in the box body 1 by a square grid plate 6, the two ends of the box body 1 are respectively equipped with support members 7, the two ends of the square grid plate 6 are respectively supported on the corresponding support members 7, and the screen cloth 3 is supported on On the square grid plate 6, the screen cloth 3 and the square grid plate 6 can be freely taken out.

[0015] The upper end of the upper chamber 4 located at...

Abstract

The utility model relates to a leachate suspended substance removal device of a garbage power plant, which relates to the field of environmental protection power generation equipment. It includes a box body and a box cover connected to the upper end of the box body. The box body is provided with an obliquely arranged screen to divide the box body into an upper cavity and a lower cavity. The inlet, the lower part of the upper cavity located at the lower end of the screen is provided with a slag outlet, and the lower part of the lower cavity is provided with a water outlet. The leachate enters the box through the leachate inlet, and the leachate has a flushing effect on the screen, which can flush the filter residue to the slag discharge port and reduce the clogging rate of the screen. The leachate flows into the adjustment tank by itself, and there is basically no stagnant water on the screen, which is convenient for drying and cleaning the filter residue.

Description

technical field [0001] The invention relates to the field of environmental protection power generation equipment, in particular to a device for removing suspended matter in leachate of a garbage power plant. Background technique [0002] The landfill leachate from the waste incineration plant has been separated by the grid in the waste pit, and still contains a large amount of fine fiber matter. If it is not removed before entering the adjustment tank, it will seriously affect the normal operation of the subsequent treatment process. [0003] Adding grids is a common solution. The grids can be divided into artificial grids and mechanical grids. Mechanical grids have high manufacturing requirements, occupy a large area, and have a high failure rate. Biogas will be generated in the leachate adjustment tank. Use Mechanical grills have a high risk factor. Artificial grilles have relatively low manufacturing requirements, small footprint, low failure rate, and low risk factor, b...
