A decontaminated exhaust system 10 according to an embodiment of the present invention is described below with reference to fig. 1.

According to the utility model discloses the clean discharge system 10 of the first aspect embodiment, clean discharge system 10 for purify liquid, including transfer line 200, first filter tank 100, second filter tank 300 and water oil separator 500. The first filtering tank 100 includes a filtering net 110, the filtering net 110 is attached to an inner wall of the first filtering tank 100, and the filtering net 110 is capable of filtering solid contaminants in the liquid flowing through the first filtering tank 100. One end of the infusion device is connected to the oil-water separator 500, and the other end is connected to the second filtering tank 300. The second filtering tank 300 is communicated with the first filtering tank 100 through the liquid feeding passage 200, the second filtering tank 300 comprises a filter cotton 310 and a liquid feeding device (not marked in the figure), the filter cotton 310 is connected to the inner wall of the second filtering tank 300 and can filter oil and water in the liquid from the first filtering tank 100. The oil-water separator 500 is connected to the second filter tank 300 via a fluid transfer device, and can separate oil and water in the liquid from the second filter tank 300.

Specifically, referring to fig. 1, the wastewater produced in industrial production contains not only solid contaminants but also oil stains. The first filtering tank 100 and the second filtering tank 300 are both hollow cuboids. The upper end of the first filtering tank 100 is provided with an opening through which the liquid can flow into the first filtering tank 100, and the liquid passes through the filtering net 110 in the first filtering tank 100 under the action of gravity. When the liquid passes through the first filter 111, the first filter 111 can block solid pollutants in the liquid, so as to achieve the first purification of the liquid. One end of the introduction path 200 is connected to the lower end of the first filtering tank 100, and the other end is connected to the upper end of the second filtering tank 300. After the liquid passes through the first filter 111, the liquid can enter the feeding passage 200 under the gravity and flow into the second filter tank 300 through the feeding passage 200. Since the second filtering tank 300 is provided with the filter pulp 310, the liquid after the first purification can be purified for the second time, thereby filtering a part of the oil stains.

The infusion device is a suction pump 410 and a water pipe 420, and a suction port of the suction pump 410 is positioned at the lower end of the filter pulp 310. After the liquid flows through the filter cotton 310, the liquid can be pumped by the water pump 410, and then enters the oil-water separator 500 through the water pipe 420, and the oil-water separation of the liquid is further completed through the operation of the oil-water separator 500, so that the purification of the liquid is finally realized.

It is understood that the bottom surface of the first filter tank 100 may be a conical surface, and the cross-sectional area of the bottom surface of the first filter tank 100 is gradually reduced along the flow direction of the liquid and is connected to the feeding passage 200 at a position where the cross-sectional area is the smallest, thereby preventing the liquid left at the bottom of the first filter tank 100 from not entering the second filter tank 300 after the liquid purification is completed. A driving member such as a motor and a water pump can be arranged between the first filtering tank 100 and the second filtering tank 300 to drive the liquid to enter the liquid conveying channel 200.

The infusion device can also be a pipeline, a water pumping motor and the like, when the infusion device is a pipeline, the height of one end of the pipeline, which is connected with the oil-water separator 500, is smaller than that of one end of the pipeline, which is connected with the second filter tank 300, so that the effect of conveying liquid from the second filter tank 300 to the oil-water separator 500 through gravity is achieved. The opening of the first filter tank 100 may be provided in a side wall of the first filter tank 100, thereby facilitating installation of a liquid transport unit such as a pipe. The first filtering tank 100 and the second filtering tank 300 may also have a cylindrical shape, a hollow triangular prism shape, etc., thereby being adapted to different installation environments.

In some embodiments, the filter cotton 310 is connected to the infusion channel 200 and the periphery of the connection opening 210 of the second filter tank 300, and covers the connection opening 210. In particular, reference is made to fig. 1. The supply passage 200 is connected to the upper end of the second filter tank 300 to form a connection port 210, and the liquid is supplied from the connection port 210 into the second filter tank 300. Because the filter cotton 310 is connected to the periphery of the connection port 210 and covers the connection port 210, the purification drainage system 10 can reduce the installation space and the required volume of the filter cotton 310 while avoiding the liquid entering the infusion set without passing through the filter cotton 310, thereby reducing the cost of the purification drainage system 10.

In some embodiments, the filter screens 110 include a first filter screen 111, a second filter screen 112, and a third filter screen 113, the first filter screen 111, the second filter screen 112, and the third filter screen 113 are disposed along a flow direction of the contaminants in the first filter tank 100, and the mesh numbers of the first filter screen, the second filter screen 112, and the third filter screen 113 are sequentially increased by two. Specifically, referring to fig. 1, since the filter screen 110 includes the first filter screen 111, the second filter screen 112 and the third filter screen 113, and the number of the filter screens 110 is increased by doubling in turn, when the liquid passes through the filter screen 110, the solid contaminants can be filtered in a form of multiple filtering and layer-by-layer filtering, thereby preventing all the solid contaminants from being accumulated on one filter screen 110, and reducing the filtering efficiency.

In some embodiments, first filter 111 has a mesh count of 50, second filter 112 has a mesh count of 100, and third filter 113 has a mesh count of 200. Specifically, the larger the number of meshes on a screen made of the same material, the more expensive the cost tends to be due to the same size. Therefore, the number of meshes of the first screen 111, the number of meshes of the second screen 112, and the number of meshes of the third screen 113 provided in the first filtering tank 100 are 50, 100, and 200, respectively, so that the production cost of the screens can be reduced while ensuring the filtering effect.

In some embodiments, the filter cotton 310 includes a first filter cotton 311, a second filter cotton 312 and a third filter cotton 313, the first filter cotton 311, the second filter cotton 312 and the third filter cotton 313 are arranged along the flowing direction of the liquid in the second filter tank 300, the filtering sizes of the first filter cotton 311, the second filter cotton 312 and the third filter cotton 313 are sequentially reduced, and the filtering precision is sequentially improved. Specifically, referring to fig. 1, due to the first filter cotton 311, the second filter cotton 312 and the third filter cotton 313, multiple times of filtration and layer-by-layer filtration of oil and water in liquid can be realized, thereby preventing oil from accumulating on a certain filtration surface and affecting the filtration effect of oil and water.

In some embodiments, the first filter cotton 311 has a filter size of 3 microns, the second filter cotton 312 has a filter size of 1 micron, and the third filter cotton 313 has a filter size of 0.5 micron. Specifically, since the filter cotton 310 has the same size and material, the smaller the filter size is, the higher the production cost is. Therefore, by setting the filtering size of the first filter cotton 311 to be 3 micrometers, the filtering size of the second filter cotton 312 to be 1 micrometer, and the filtering size of the third filter cotton 313 to be 0.5 micrometer in the second filtering tank 300, the production cost of the filtering surface can be reduced while the filtering effect of oil and water is ensured.

In some embodiments, the infusion device comprises a water pump 410 and a water pipe 420, wherein the water pump 410 is arranged at the bottom of the second filter tank 300, one end of the water pipe 420 is connected with the water pump 410, and the other end of the water pipe 420 is connected with the oil-water separator 500. Specifically, referring to fig. 1, since the liquid feeding device is the water pump 410 and the water pipe 420, when the oil-water separator 500 needs to be installed underground, it is not necessary to introduce the liquid in the second filtering tank 300 into the oil-water separator 500 by gravity, thereby avoiding the installation of the oil-water separator 500 at a deeper ground bottom and reducing the installation cost of the oil-water separator 500. Compared with the liquid conveying by means of a water pumping motor, gravity and the like, the conveying mode of the conveying device consisting of the water pumping pump 410 and the water pipe 420 is adopted, so that the conveying efficiency is guaranteed, and meanwhile, the production cost of the purification and discharge system 10 is reduced.

In some embodiments, infusion channel 200 comprises a first channel 220, a second channel 230, and a third channel 240, the first channel 220 being connected to the first filter tank 100 and being vertically connected to the second channel 230, and the third channel 240 being connected to the second filter tank 300 and being vertically connected to the second channel 230. Specifically, referring to fig. 1, since the flow rate of the liquid entering the first filter tank 100 tends to be large, and the passable aperture and strength of the filter cotton 310 tend to be smaller than those of the filter net 110, if the liquid enters the second filter tank 300 from the first filter tank 100 in a straight line, the liquid may break through the filter cotton 310. Therefore, the flow rate of the liquid needs to be limited. When the first channel 220 and the third channel 240 are perpendicular to the second channel 230, the liquid can impact the inner wall of the infusion channel 200 when turning, so as to achieve the effect of deceleration, thereby preventing the filter cotton 310 from being broken by the liquid.

In some embodiments, the oil water separator 500 is a centrifugal oil water separator 500. Specifically, since the oil-water separator 500 is a centrifugal oil-water separator 500, oil-water separation can be preferably performed, thereby improving the purification efficiency of the purification discharge system 10.

In some embodiments, the first filter tank 100 further includes a valve (not shown) and is provided with a liquid inlet, and the valve is provided at the liquid inlet and can control the liquid inlet to be closed or opened.
