Problems solved by technology

With the separation method of gravity sedimentation, the wastewater generally needs to go through the slag removal machine for preliminary slag removal, and then settles through the settling tank. Therefore, the above-mentioned equipment takes a long time to treat wastewater, and because the above-mentioned equipment is generally large in size, Moreover, the slag extractor needs relatively complicated internal parts to complete the separation process, so the cost of using the above-mentioned equipment is relatively high, and the construction cost of the matching civil engineering is also relatively high; Therefore, high-pressure solid-containing wastewater needs to be decompressed, resulting in waste of pressure energy in high-pressure solid-containing wastewater

Embodiment 1

[0034] Embodiment 1: as Figure 1-4As shown, a device for separating solid-containing wastewater includes a housing 1; three sewage inlets 1.1 are arranged on the side wall of the housing 1, and the sewage inlets 1.1 are arranged along the tangential direction of the housing 1; below the sewage inlet 1.1 A separation plate 2 is fixed horizontally in the housing 1; an annular gap 3 is formed between the edge of the separation plate 2 and the inner wall of the housing 1; a mud discharge port 1.2 is opened on the housing 1 below the separation plate 2; 1.1 A filter plate 4 is horizontally fixed in the housing 1 above the filter plate 4; a water outlet 1.3 is opened on the side wall of the housing 1 above the filter plate 4, and the housing 1 above the water outlet 1.3 is conical, which can float on the water surface The dust gathers on the top to facilitate the stratification of the lower wastewater liquid and the upper layer of floating impurities, forming thicker floating impur...

Embodiment 2

[0041] Embodiment 2: Utilize the device of embodiment 1 to carry out the control method of separating solid-containing waste water, it may further comprise the steps:

[0042] (1) Separation for the first time: solid waste water enters the shell 1 from the sewage inlet 1.1 along the tangential direction of the shell 1 to form a vortex; the sludge with large particle size flows from the annular gap 3 to the bottom of the shell 1 under centrifugal action, Discharge from the mud discharge pipe 18;

[0043] (2) Separation for the second time: the waste water after step 1 is separated for the first time is filtered through filter plate 4 to remove impurities;

[0044] (3) The third separation: in step 2, the fine ash and light oil impurities that cannot be filtered by the filter plate 4 float on the surface of the waste water above the housing 1, are collected by the collection tank 5, and are discharged from the slag discharge pipe 6, and the collection tank The waste water betwe...

Abstract

The invention discloses a solid-containing wastewater separation device and a solid-containing wastewater separation control method. The device comprises a shell, wherein a sewage inlet is arranged along the tangential direction of the shell; a separation plate is horizontally and fixedly arranged in the shell below the sewage inlet; a filter plate is horizontally fixed in the shell above the sewage inlet; a water outlet is formed in the side wall of the shell above the filter plate; and a collecting tank with an opening in the top is fixedly arranged in the shell above the water outlet. The method comprises the steps of (1) conducting primary separation; (2) conducting secondary separation; and (3) conducting third separation. The beneficial effects are that the solid-containing wastewater separation device is simple in structure and easy to implement; the treatment system of the solid-containing wastewater is simplified, the investment of equipment and civil engineering is reduced, and the treatment cost of the wastewater is reduced; the waste of pressure energy is avoided; and the method disclosed by the invention is simple in process, the quality of the wastewater discharged from the water outlet is ensured, and liquid-solid separation in the solid-containing wastewater is effectively realized.

Description

Technical field: [0001] The patent of the invention belongs to the technical field of fluidized bed gasification furnace slagging, and specifically relates to a device for separating solid-containing wastewater and a control method for separating solid-containing wastewater. Background technique: [0002] Solid waste water refers to waste water mainly containing slag, dust and other impurities, which is the main component of sewage in the process of coal gasification. Its biggest feature is that the content of ash and insoluble dust in waste water is relatively large. , will cause great environmental pollution and waste of resources. [0003] The existing solid-containing wastewater separation method is mainly natural sedimentation, that is, the solid particles are separated from the sewage by gravity sedimentation. With the separation method of gravity sedimentation, the wastewater generally needs to go through the slag removal machine for preliminary slag removal, and the...
