Description

Technical Field

[0001] This utility model relates to the technical field of chemical condensate water treatment, and in particular to a filtration device for chemical condensate water purification. Background Technology

[0002] Condensate generally refers to the water that condenses after the steam generated in the boiler has done work in the turbine, cooled by circulating cooling water. In reality, condensate from the condenser hot well also includes drains from high-pressure heaters and low-pressure heaters. Due to unavoidable steam and water losses in the thermal system, a certain amount of makeup water needs to be added. Therefore, condensate mainly includes: condensate from the steam in the turbine after it has done work, various drains, and boiler makeup water.

[0003] Current condensate polishing filtration devices can effectively filter and intercept condensate. However, due to the presence of large impurities in the condensate, the filter elements of the devices become clogged. This necessitates timely replacement and cleaning of the filter screens by maintenance personnel, reducing the filtration efficiency of the condensate and affecting the overall treatment efficiency of the condensate polishing process. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a filtration device for chemical condensate water purification.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A filtration device for chemical condensate water polishing includes a housing, multiple filter plates, and multiple cleaning plates. The internal space of the housing is divided into a filtration chamber and a receiving chamber by a horizontally arranged partition from bottom to top. Multiple filter plates are vertically installed at even intervals along one end of the housing in the filtration chamber. Multiple cleaning plates are vertically installed in the receiving chamber and are positioned above the multiple filter plates. The cleaning plates can move downward through the partition to clean the filter plates.

[0007] The top of the housing and the partition have multiple pairs of through openings, which are located above the filter plate. The cleaning plate can move up and down along the openings on the partition.

[0008] The opening is a long, narrow shape.

[0009] The cleaning plate has an inverted U-shaped structure. The bottom of the cleaning plate is located inside the opening of the partition. The cleaning plate is located above the filter plate, and the lower ends of the inner walls of the two sides of the cleaning plate are respectively attached to the two sides of the filter plate.

[0010] A vertically positioned lifting rod is connected to the closed end of the cleaning plate, with the upper end of the lifting rod extending out of the opening at the top of the box.

[0011] The lifting rod has an inverted U-shaped structure, with one side of the lower end of the lifting rod rotatably connected to the closed end of the cleaning plate; when the cleaning plate is moved up into the storage cavity, the lifting rod can rotate to the other side of the lower end to overlap the opening at the top of the box.

[0012] The pore size of the filter plates gradually decreases along the direction of condensate flow.

[0013] The two ends of the housing are equipped with an inlet pipe and an outlet pipe, respectively. The inlet pipe is close to the filter plate with the largest pore size, and the outlet pipe is close to the filter plate with the smallest pore size.

[0014] The housing has a rectangular box-like structure, and the filter plate has a rectangular mesh-like structure. The edges of the filter plate are respectively attached to the inner wall of the filter chamber and the partition.

[0015] One side of the housing is open, corresponding to the filter chamber, and is fitted with an openable and closable door panel. A sealing ring is installed between the edge of the door panel and the open side of the housing.

[0016] The beneficial effects of this utility model are: the utility model has a simple structure and reasonable design, and can realize step-by-step filtration of chemical condensate water purification, remove impurities in the condensate water, and achieve better filtration effect; in addition, it can also clean multiple filter plates, remove impurities adhering to the filter plates, and avoid clogging of the filter pores on the filter plates, which would affect the filtration effect.
