Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a desulfurization wastewater treatment device for a power plant. Background Art

[0002] Desulfurization wastewater is mainly the discharge water from the absorption tower during the wet desulfurization process of boiler flue gas. Desulfurization wastewater contains a variety of harmful impurities, including nitrite, sulfate, heavy metals and other harmful substances. Usually, alkaline substances are added to the desulfurization wastewater before discharge to react with the harmful substances in the desulfurization wastewater to generate precipitates, and then the harmless wastewater is discharged. However, when the wastewater is discharged, a filter plate is usually used to retain the precipitates, and then the wastewater is discharged through the filter holes. During filtration, some precipitates may clog the filter holes, thereby affecting the subsequent discharge of wastewater.

[0003] A search for the above-mentioned problem revealed that in the currently disclosed prior art, such as the desulfurization wastewater treatment device proposed in the publication number CN217409870U, a push plate is installed on the side of the filter plate. After the reaction, the push plate is pushed to push the precipitate to the slag discharge port on the side, thereby avoiding the clogging of the filter holes by the precipitate. However, when pushing the precipitate, a certain amount of wastewater will be left on the filter plate more or less, and the wastewater and the precipitate may be pushed to the slag discharge port together during the pushing. Over time, a large amount of wastewater may accumulate at the slag discharge port, and the precipitate at the slag discharge port may be flushed back onto the filter plate, which may cause the filter holes to be blocked again.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1~Figure 5 As shown, this embodiment proposes a desulfurization wastewater treatment device for a power plant, including a box body 1, a feed barrel 2, a filter plate 3, a water baffle 4, a slide rail 5, a slide plate 6, a wiper assembly and a material receiving assembly. A feed port is provided on the top of the box body 1, a drain port is provided on the side of the box body 1, the feed barrel 2 is fixedly installed on the box body 1, the filter plate 3 is fixedly installed in the box body 1, the water baffle 4 is slidably installed on the box body 1, two slide rails 5 are provided, and the slide rails 5 are fixedly installed on the side of the box body 1, two slide rails 6 are provided, and the slide plate 6 is slidably installed on the slide rails 5, the wiper assembly is provided on the water baffle 4, and the material receiving assembly is provided on the box body 1.

[0025] In this embodiment, the wiper assembly includes a fixed block 101 and a brush 102. The fixed block 101 is fixedly installed at the bottom of the water baffle plate 4, and the brush 102 is fixedly installed on the fixed block 101. By moving the water baffle plate 4, the fixed block 101 and the brush 102 can be driven to clean the wastewater on the filter plate 3 and let it flow through the filter holes of the filter plate 3.

[0026] In this embodiment, the material collecting assembly includes a support plate 201, a collecting box 202, a cylinder 203, a support frame 204, a transmission shaft 205, a motor 206 and a scraper 207. The support plate 201 is fixedly mounted on the side of the box body 1, the collecting box 202 is slidably mounted on the support plate 201 and the filter plate 3, and the collecting box 202 is provided with filter holes. The cylinder 203 is fixedly mounted on the support plate 201, and the output end of the cylinder 203 is fixedly connected to the collecting box 202. The number of support frames 204 is set to two, and the support frame 204 is fixedly mounted on the collecting box 202. The number of transmission shafts 205 is set to two, and the transmission shaft 205 is rotatably mounted on the support frame 204. The number of motors 206 is set to two, and the motor 206 is fixedly mounted on the support frame 204, and the output end of the motor 206 is fixedly connected to the transmission shaft 205. The scraper 207 is fixedly mounted on the transmission shaft 205. By moving the collecting box 202, the transmission shaft 205 drives the scraper 207 to rotate, thereby collecting the sediment.

[0027] In this embodiment, a through slot is opened on the side of the box body 1, a baffle 301 is hingedly installed at the through slot, and the collection box 202 can pass through the through slot. After the reaction is completed, the baffle 301 is opened and the collection box 202 is pushed onto the filter plate 3 to collect and clean the precipitate.

[0028] In this embodiment, an inclined plate 302 is fixedly installed on the side of the collection box 202 , and the inclined plate 302 is in contact with the support plate 201 . When scraping the sediment, the scraper 207 can scrape the sediment into the collection box 202 through the inclined plate 302 .

[0029] In this embodiment, the slide plate 6 fits with the drainage hole of the housing 1. When the desulfurization wastewater reacts, the slide plate 6 can block the drainage hole to prevent the wastewater from flowing out through the drainage hole during the reaction.

[0030] In summary, when the desulfurization wastewater treatment device treats wastewater, first the wastewater and reactants are placed into the box body 1 through the feed tube 2 to react. After the reaction is completed, the water baffle plate 4 is pulled and pulled out to make the wastewater flow to the filter plate 3. The reacted wastewater flows down through the filter holes, and the sediment is retained on the filter plate 3. Then the water baffle plate 4 is pulled again to drive the fixed block 101 and the brush 102 to clean the wastewater remaining on the surface of the filter plate 3. The brush 102 is moved back and forth to scrape the wastewater retained on the filter plate 3. During the scraping, the slide plate 6 can be pulled to leak out the drainage hole, and the wastewater can be discharged through the drainage port, or it can be discharged to the bottom through the filter holes of the filter plate 3. After the scraping is completed, the baffle 301 is opened, the cylinder 203 is started, the collection box 202 is pushed onto the filter plate 3, and the motor 206 is started. The motor 206 is a micro motor 206, which drives the transmission shaft 205 to rotate, and the transmission shaft 205 drives the scraper 207 to rotate, so that the sediment on the filter plate 3 is scraped into the collection box 202. If the residual waste water is scraped into the collection box 202 during scraping, it can flow out through the filter holes of the collection box 202. Too much waste water will not be retained in the collection box 202, and the collection of sediment will not be affected. When the waste water reacts, the scraper 207 can be moved to the baffle 301 to resist it to prevent the waste water from flushing the baffle 301 during the reaction.
