Description

[Technical field]

[0001] The invention relates to the technical field of filters, in particular to the technical field of a dissolving-contamination type filter. [Background technology]

[0002] In the nuclear power or thermal power condensate polishing system, all wastewater generated during the conveying of resin and regeneration needs to be collected in the wastewater neutralization tank, neutralized to a pH value of 6 to 9, and then sent to the waste liquid discharge system of the whole plant. In the usual configuration, there is no treatment unit for filtering the wastewater sent to the waste liquid discharge system of the whole plant, or only a pipeline Y-type filter is set for simple pollution interception. For the former, the particulate matter in the wastewater neutralization tank cannot be intercepted, and the wastewater conveying system will directly carry the impurities such as the conveying resin and the broken resin generated during the regeneration to the waste liquid discharge system of the whole plant, which brings treatment difficulties and burdens to the waste liquid discharge system of the whole plant. However, the method of using a pipe-type Y-type filter for simple sewage interception treatment has the following problems: 1. The flow rate of the wastewater transport main line is relatively high, which makes it difficult for particles to be deposited in the pipe-type Y-type filter branch pipe, and the high flow rate of the wastewater transport main line is also very likely to carry out particles that have been deposited in the pipe-type Y-type filter branch pipe; 2. Due to the limited pollution holding capacity of the pipe-type Y-type filter, it needs to be frequently disassembled and assembled to clean the particles deposited in the pipe-type Y-type filter, resulting in a large amount of maintenance workload during operation; 3. For the particles cleaned out after each disassembly and assembly of the pipe-type Y-type filter, there is still the problem of secondary waste disposal; 4. The pipe-type Y-type filter has inherent defects in its service life, resulting in frequent procurement and storage of spare parts for the pipe-type Y-type filter. [Summary of the invention]

[0003] The purpose of the present invention is to solve the problems in the prior art and to propose a dissolving filter, in which a dirt holding chamber is provided to provide sufficient space for holding dirt.

[Specific implementation method]

[0017] See also Figure 1 The present invention discloses a pollution dissolving filter, comprising a filter body 1 and a plurality of filter elements, wherein the filter body 1 comprises a cylinder 11, an upper cover 12 and a lower cover 13, wherein the upper cover 12 and the lower cover 13 are detachably fixed to the top and bottom ends of the cylinder 11, respectively, and a pollution collecting plate group is fixed on the inner wall of the cylinder 11, wherein the pollution collecting plate group divides the inner cavity of the cylinder 11 into a working cavity 113 located above the pollution collecting plate group and a pollution containing cavity 114 located below the pollution collecting plate group, wherein the pollution collecting plate group is provided with a pollution leakage port for small and medium-sized pollution to enter the pollution containing cavity 114 from the working cavity 113, and the outer side of the cylinder 11 is provided with a water inlet 111 and a plurality of water outlets 112 respectively connected with the working cavity 113, and the filter elements are respectively fixed at the water outlets 112, and the bottom end of the lower cover 13 is provided with a sewage discharge port 131 connected with the pollution containing cavity 114, and the outer side of the cylinder 11 A hand hole 115 connected to the working chamber 113 is provided, and an exhaust port 121 connected to the working chamber 113 is provided at the top of the upper cover body 12. The sewage collecting plate group includes a plurality of first sewage collecting plate bodies 2 and a plurality of second sewage collecting plate bodies 3. The first sewage collecting plate body 2 is located above the second sewage collecting plate body 3. The first sewage collecting plate body 2 and the second sewage collecting plate body 3 are respectively provided with sewage leakage ports. The bottom surface of the first sewage collecting plate body 2 and the outer edge of the sewage leakage port are respectively provided with sewage collecting pipes 21. An annular baffle plate 4 is provided on the inner wall of the cylinder 11 and is located in the sewage containing chamber 114. The inner diameter of the annular baffle plate 4 gradually decreases from top to bottom. A plurality of supporting legs 5 are arranged around the bottom end of the outer wall of the cylinder 11.

[0018] Working process of the present invention:

[0019] First, the sewage to be filtered enters the working chamber 113 through the water inlet 111. Due to the sudden increase in the water flow area, the water flow rate drops sharply, and the dirt carried in the sewage will settle under the action of gravity. Among them, large dirt is directly trapped on the sewage collecting plate group, while small and medium-sized dirt passes through the sewage collecting plate group and the annular baffle 4 in turn, and is then temporarily stored in the sewage holding chamber 114, and will not be carried out of the filter body 1 by subsequent sewage due to changes in operating conditions. The water is further filtered through the filter element in the water outlet 112 and then discharged, while the gas is discharged through the exhaust port 121. After the dirt in the sewage holding chamber 114 is collected to a certain extent, it can be discharged through the sewage outlet 131. The large dirt trapped on the sewage collecting plate group can be manually cleaned by opening the hand hole 115.

[0020] The specifications and quantity of the water outlet 112, the sewage outlet and the sewage collecting pipe 21 are matched with the operation parameters.

[0021] The present invention can filter the wastewater in the wastewater neutralization pool, thereby intercepting the particulate impurities in the wastewater, effectively reducing the processing difficulties and burdens of the waste liquid discharge system of the whole plant. Compared with the prior art, the sewage chamber is provided to provide sufficient accommodating space, and the sewage collecting plate group and the annular baffle are used to ensure that the contained particulate matter will not be stirred out and cause secondary pollution. The contained collected materials can be discharged and processed separately according to the situation, without frequent disassembly and maintenance, and without frequent spare parts procurement. The overall performance is reliable and the structure is simple.
