Description

Technical Field

[0001] This utility model relates to the field of washing water recycling technology, and in particular to a washing water recycling device for desulfurization washing towers. Background Technology

[0002] In industrial production, desulfurization scrubbing towers are important environmental protection equipment. Their washing water recycling devices play a key role in reducing costs, improving resource utilization, and reducing environmental pollution. They mainly improve water resource utilization, reduce desulfurization costs, ensure desulfurization effects, and reduce environmental pollution. They typically include a circulating water tank that buffers and stabilizes the system water volume, a circulating water pump that powers the washing water, a filtration device that filters impurities in the circulating water, a dosing device that adds desulfurizing agents and other chemicals to the circulating water, and a monitoring device that monitors the water quality parameters of the circulating water in real time.

[0003] However, existing desulfurization scrubbing tower washing water recycling devices have some problems. For example, during long-term contact with the circulating water, the circulating water tank is prone to the growth of various types of dirt, including impurities, sediments, and scale. These dirt not only affect the washing effect but may also cause equipment malfunctions, increase cleaning difficulty and cost. If the washing water also contains acid or alkali, as well as dissolved oxygen, these will corrode the inner wall of the circulating water tank and even cause leakage. In order to overcome the shortcomings of the existing technology, we propose a desulfurization scrubbing tower washing water recycling device. Utility Model Content

[0004] The main purpose of this invention is to provide a device for recycling washing water from a desulfurization washing tower, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The desulfurization washing tower washing water recycling device includes a tower body, a circulating water tank, and a circulating water pump. The circulating water tank and the bottom cylinder at the lowest end of the tower body are interconnected. The inlet of the circulating water pump is connected to the inner cavity of the circulating water tank through a water pumping pipe, and the outlet of the circulating water pump is connected to the inner cavity at the upper end of the tower body through a water delivery pipe. An integrated cylindrical geomembrane is detachably and fitted into the interconnected circulating water tank and the inner cavity of the bottom cylinder.

[0007] Preferably, the opening edge of the integrated cylindrical geomembrane is sealed with a plastic band.

[0008] Preferably, the lower inner cavities of the bottom cylinder and the circulating water tank are provided with water-blocking grooves that expand from each other, and the plastic belt is fitted and installed on the top of the water-blocking grooves.

[0009] Preferably, a gravity-type snap-fit ​​structure is provided between the plastic belt ring and the circulating water tank.

[0010] Preferably, the gravity-type snap-fit ​​structure is mainly composed of several mutually interlocking positioning posts and positioning holes. The positioning posts are fixedly installed on the outer periphery of the plastic band, and the positioning holes are connected and set on the outer periphery of the top of the water-blocking groove.

[0011] Preferably, a barb is protruding upward from the end of the positioning post, and a corresponding slot is provided above the end of the positioning hole.

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model utilizes an integrated cylindrical geomembrane made of virgin polyethylene resin. This geomembrane is impermeable, effectively preventing direct contact between the inner wall of the circulating water tank and the bottom cylinder and the circulating water. It successfully blocks impurities, sediments, and scale from forming and accumulating on the tank walls, significantly reducing scale buildup and preventing corrosion from washing water. When cleaning is required, the geomembrane prevents stubborn dirt from adhering to the inner wall. A simple rinse with appropriate detergent and water quickly restores the tank and bottom cylinder to a clean state, reducing cleaning difficulty and cost, and providing strong support for the continuous and efficient operation of the circulating water tank.

[0015] 2. The integrated cylindrical geomembrane in this utility model can be quickly installed or disassembled through a gravity-type snap-fit ​​structure between the plastic band at the upper opening edge and the circulating water tank. This facilitates the installation and disassembly of the integrated cylindrical geomembrane. After water is filled, gravity causes the positioning post hooks to be tightly engaged with the slots, resulting in high stability. After drainage, it can be easily disassembled, facilitating equipment maintenance. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-3 As shown, the desulfurization washing tower washing water recycling device includes a tower body 1, a circulating water tank 2, and a circulating water pump 3. The circulating water tank 2 and the bottom cylinder 101 at the lowest end of the tower body 1 are interconnected. The inlet of the circulating water pump 3 is connected to the inner cavity of the circulating water tank 2 through a water extraction pipe 301, and the outlet of the circulating water pump 3 is connected to the inner cavity at the upper end of the tower body 1 through a water delivery pipe 302. That is, the circulating water pump 3 draws water from the circulating water tank 2 and delivers it to the upper end of the tower body 1 for spraying and falling, which is then concentrated into the bottom cylinder 101 at the lowest end of the tower body 1 and the circulating water tank 2, thereby improving the utilization rate of water resources and reducing desulfurization costs. A maintenance door 201 is installed on one side of the maintenance port at the upper end of the circulating water tank 2. After the maintenance door 201 is opened, it is convenient for construction personnel to enter the bottom cylinder 101 and the circulating water tank 2 for maintenance.

[0022] It should be added that a filter is fixedly installed inside the bottom cylinder 101 to filter impurities in the circulating water, removing solid particles, suspended matter, and other impurities to prevent their accumulation in the system, which could affect the washing effect and normal operation of the equipment. This improves the cleanliness of the circulating water and extends the service life of the equipment. The circulating water tank 2 is equipped with a feeding machine for adding desulfurizing agents and other chemicals to the circulating water. According to the desulfurization requirements, an appropriate amount of desulfurizing agent is added precisely to enhance the desulfurization capacity of the washing water and ensure the desulfurization effect. At the same time, some corrosion inhibitors can also be added to prevent equipment corrosion. The circulating water tank 2 is also equipped with sensors for detecting pH value, sulfur content, and turbidity parameters to adjust the dosage and control the quality of the circulating water in a timely manner, ensuring stable system operation.

[0023] In this embodiment, an integrated cylindrical geomembrane 202 is detachably and fitted into the interconnected circulating water tank 2 and the inner cavity of the bottom cylinder 101. The integrated cylindrical geomembrane 202 is made of polyethylene virgin resin, and its main function is to prevent liquid leakage. The impermeability of the integrated cylindrical geomembrane 202 prevents the inner wall of the circulating water tank 2 and the bottom cylinder 101 from directly contacting the circulating water, effectively preventing the growth and accumulation of various types of dirt on the inner wall of the circulating water tank 2 and the bottom cylinder 101. Whether it is impurities, sediments, or scale that may be generated due to long-term use, they can all be successfully blocked by the geomembrane. In this way, not only is the generation of dirt greatly reduced, but the cleaning of the circulating water tank 2 also becomes easier and more convenient.

[0024] When the circulating water tank 2 needs to be cleaned, due to the presence of the integrated cylindrical geomembrane 202, dirt will not stubbornly adhere to the inner wall of the circulating water tank 2. Simply rinse with an appropriate amount of detergent and water to quickly restore the circulating water tank 2 and the inner wall of the bottom cylinder 101 to a clean and tidy state, providing a strong guarantee for the continuous and efficient operation of the circulating water tank 2.

[0025] In this embodiment, the opening edge of the integrated cylindrical geomembrane 202 is sealed with a plastic band 204. The plastic band 204 is mainly used to enhance the mechanical strength of the opening edge of the integrated cylindrical geomembrane 202. The lower inner cavity of the bottom cylinder 101 and the circulating water tank 2 are provided with a water-blocking groove 206 that expands with each other. The plastic band 204 is fitted and installed on the top of the water-blocking groove 206. The water-blocking groove 206 mainly covers the plastic band 204, which can effectively prevent water falling from the upper end of the tower body 1 from flowing into the space between the integrated cylindrical geomembrane 202 and the inner wall of the bottom cylinder 101.

[0026] In this embodiment, the lower end of the integrated cylindrical geomembrane 202 is provided with a first circular hole 203, and the lower end of the circulating water tank 2 is provided with a second circular hole 205 that corresponds to and communicates with the first circular hole 203. A sealing tube 4 is embedded in the first circular hole 203 and the second circular hole 205. A sealing ring 401 is coaxially fixedly connected to the first end of the sealing tube 4. A sealing gasket 403 is attached to the inner end face of the sealing ring 401. An external thread 402 is provided on the outer periphery of the end of the sealing tube 4. 2. A nut 404 is threaded onto the end of the sealing tube 4. A sealing gasket 403 is located inside the integrated cylindrical geomembrane 202. The nut 404 is located outside the circulating water tank 2. By tightening the nut 404 onto the external thread 402 at the end of the sealing tube 4, the sealing tube 4 can be sealed and connected to the first round hole 203 at the lower end of the integrated cylindrical geomembrane 202. A second round hole 205 is fixedly connected to the external thread 402 at the end of the sealing tube 4, and the end of the sealing tube 4 is fixedly connected to the pumping pipe 301.

[0027] In this embodiment, a gravity-type snap-fit ​​structure is provided between the plastic belt ring 204 and the circulating water tank 2. The gravity-type snap-fit ​​structure is mainly composed of several mutually interlocking positioning posts 208 and positioning holes 207. Several positioning posts 208 are fixedly installed on the periphery of the plastic belt ring 204, and several positioning holes 207 are respectively connected to the periphery of the top of the water baffle 206. A barb 209 is protruding upward from the end of the positioning post 208, and a slot 210 corresponding to the barb 209 is also provided above the end of the positioning hole 207.

[0028] It should be noted that, in its unloaded natural state, the height of the integrated cylindrical geomembrane 202 is slightly lower than the depth of the water-retaining groove 206 in the circulating water tank 2. The integrated cylindrical geomembrane 202 utilizes its ability to slightly stretch and deform. After water is filled into the integrated cylindrical geomembrane 202, its weight increases, which pulls down the plastic belt ring 204. The downward pull of gravity on the plastic belt ring 204 will then press against the positioning post 208 on the outer ring. Figure 3 Rotating from point A as the fulcrum, the barb 209 at the end of the positioning post 208 is engaged in the slot 210. This increases the downward pulling force on the plastic band 204, making the barb 209 and the slot 210 more tightly and stably connected. When the plastic band 204 needs to be removed, the water in the integrated cylindrical geomembrane 202 needs to be drained first to reduce its weight. Then, the plastic band 204 is lifted up, and the barb 209 at the end of the positioning post 208 is pressed down, allowing the positioning post 208 to be pulled out. The water in the integrated cylindrical geomembrane 202 can also automatically push the integrated cylindrical geomembrane 202 outward to fit the bottom cylinder 101 and the inner wall of the circulating water tank 2.

[0029] This utility model discloses a desulfurization washing tower washing water recycling device. Water is drawn from the circulating water tank 2 by the circulating water pump 3 and transported to the upper part of the tower body 1 for spraying. Then, the water falls into the bottom cylinder 101 and the circulating water tank 2 to form a cycle. This design greatly improves the utilization rate of water resources and reduces the waste of water resources. At the same time, since water resources are reused, the water cost in the desulfurization process is reduced, thereby reducing the overall desulfurization cost.

[0030] The integrated cylindrical geomembrane 202, made of virgin polyethylene resin, is impermeable and prevents direct contact between the inner walls of the circulating water tank 2 and the bottom cylinder 101 and the circulating water. This successfully blocks impurities, sediments, and scale from growing and accumulating on the tank walls, greatly reducing scale buildup and preventing corrosion of the inner walls of the circulating water tank 2 and the bottom cylinder 101 by washing water. When cleaning the circulating water tank 2 and the bottom cylinder 101 is required, the integrated cylindrical geomembrane 202 prevents dirt from stubbornly adhering to the inner walls. A simple rinse with a suitable amount of detergent and water is all that's needed to quickly restore the inner walls of the circulating water tank 2 and the bottom cylinder 101 to a clean state, reducing cleaning difficulty and cost and providing a strong guarantee for the continuous and efficient operation of the circulating water tank 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
