Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict. For the convenience of description, the words "up", "down", "left" and "right" appear in the following text, which only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

As shown in FIG. 2 , a filter system sewage treatment equipment provided in this embodiment includes a bag filter 1 and an ultrafiltration system 2 .

In the bag filter 1, the liquid enters the filter bag supported by the mesh basket through the liquid inlet, the solid particles in which the liquid is filtered through the filter bag are intercepted in the filter bag, and the filtrate flows out from the liquid outlet. When the fixed particles in the bag reach the upper limit, the filter bag can be replaced and used again. The bag filter 1 is designed for a steel pressure vessel and is made of high-quality and pure stainless steel, with good sealing performance, excellent corrosion resistance, refined workmanship, and safety and reliability. Single-bag filter or multi-bag filter can be used. The multi-bag filter is suitable for large-flow liquid filtration and occasions where the filter bag is replaced after a long period of use. From 2 bags to 24 bags of different specifications, the inlet and outlet diameters are 2"-18", the maximum flow rate of a single machine: 80-960 cubic meters / hour, can be designed as a quick-opening structure, so that the filter bag can be replaced easily.

As shown in Figures 1 and 2, Figure 1 is a schematic diagram when the first side plate, the second side plate and the enclosure plate are made of transparent materials in order to clearly reflect the position and direction of the filter residue plate. The ultrafiltration system 2 includes a filter residue cleaning device 21 and an ultrafiltration membrane tube 22 . The filter residue cleaning device 21 includes a first side plate 211, a second side plate 212, a surrounding plate 214 connected with the first side plate 211 and the second side plate 212 to form a filter cavity 213, and a surrounding plate 214 placed obliquely on the filter The filter residue plate 215 in the cavity 213. The filter residue plate 215 is a filter screen, and the filter screen is designed and customized according to the size of the fine residue to be filtered.

One end of the obliquely placed filter residue plate 215 is spaced from the first side plate 211 to form a flushing nozzle 216 , and the flushing nozzle 216 penetrates through the enclosure plate 214 . The flushing spout 216 is provided with an end cap 218 which can be opened or closed.

The other end of the inclined residue filter plate 215 is spaced from the second side plate 212 to form a slag discharge nozzle 217 , and the slag discharge nozzle 217 penetrates through the enclosure plate 214 . The slag outlet 217 is provided with an openable or closeable end cover 218 .

The flushing nozzle 216 is located at the upper end of the residue cleaning device, and the residue discharging nozzle 217 is located at the lower end of the residue cleaning device.

The connection line between the flushing nozzle 216 and the slag discharge nozzle 217 is a vertical connection, which is the direction of the cleaning water injected into the filter residue plate for cleaning stains in the later maintenance work of the filter residue cleaning device. The connection line between the inlet port 220 and the outlet port 219 is a horizontal connection, which is the flow direction of sewage treatment.

In order to facilitate disassembly and cleaning of the filter residue plate, the first side plate 211 is detachably connected to the enclosure plate 214 , or the second side plate 212 is detachably connected to the enclosure plate 214 .

The inlet port 220 of the residue cleaning device 21 communicates with the liquid outlet of the bag filter 1 , and the outlet port 219 communicates with the ultrafiltration membrane tube 22 . When the sewage flows from the inlet port of the filter residue cleaning device 21 through the bag filter 1, the fine dirt is filtered by the filter residue plate 215, and then flows to the position of the outlet port 217 through the side wall surface of the inclined filter residue plate 215. place.

The ultrafiltration membrane tube 22 is a dynamic filtration process, and the intercepted substances can be discharged from the treated water discharge port with the ultrafiltration effluent, so as not to block the membrane surface, and it can run continuously for a long time.

A filter for preventing clogging of the ultrafiltration membrane tube 22 is provided at the connection between the outlet port 219 and the ultrafiltration membrane tube 22 . The filter is a Y-type filter or a basket filter.

Y-type filter is a small device that removes a small amount of solid particles in the liquid, which can protect the normal operation of the device. When the fluid enters the filter cartridge with a certain size filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When it needs to be cleaned, it is only necessary to take out the detachable filter cartridge and reload it after processing. Therefore, it is extremely convenient to use and maintain.

The filter structure of the basket filter is different from other filters. Because of its shape like a basket, it is called a basket filter. It is mainly composed of nozzle, cylinder, filter basket, flange, flange cover and fasteners.

As shown in Figure 2, in the sewage treatment process, the sewage is filtered by the bag filter 1 and then enters the filter residue cleaning device to filter fine residues, and then passes through the filter to the ultrafiltration effluent of the ultrafiltration membrane tube 22, and finally the treated water Discharge port discharge.

When the filter residue cleaning device 21 is cleaned, the two end caps 218 can be disassembled, water is injected into the flushing nozzle 216 , and the stains filtered by the filter residue plate are discharged from the residue discharge nozzle 217 by means of high-pressure water flushing. In addition, the first side plate or the second side plate can also be disassembled, and the filter residue plate can be taken out for cleaning or replacement.

The slag cleaning device 21 can be made of stainless steel.
