Description

Technical Field

[0001] This utility model relates to the field of hydrogen peroxide concentrate tank spray cooling technology, specifically a spray device for cooling hydrogen peroxide concentrate tank, reducing blockage and quickly clearing blockages. Background Technology

[0002] With the rapid development of industry and the continuous expansion of urban areas, the environment on which we depend for survival is suffering from increasingly serious pollution. In particular, the waste gas generated by industries such as metallurgy, chemical industry, and mining has potential hazards. In order to ensure that the exhaust gas meets emission standards, it is necessary to carry out exhaust gas desulfurization. The conventional and relatively clean exhaust gas desulfurization process is hydrogen peroxide desulfurization. Hydrogen peroxide reacts with SO2 to produce H2SO4. H2SO4 is recycled into the system without generating additional pollutants. As the key raw material for hydrogen peroxide desulfurization, the safe storage of hydrogen peroxide concentrate is extremely important. Every summer, when the ambient temperature is >35℃, the concentrate tank needs to be sprayed with water to cool it down in order to ensure that the hydrogen peroxide does not decompose.

[0003] However, the current water supply for the factory's sprinkler system relies on the sprinkler pits. After long-term operation, the sprinkler pipes are prone to blockage due to the accumulation of impurities in the water. This not only significantly reduces the cooling effect of the sprinklers but can also cause the pipes to shut off and stop spraying water, directly threatening the safety of the hydrogen peroxide concentrate storage. More importantly, because hydrogen peroxide is a strong oxidizer and can easily cause danger when exposed to open flames or high temperatures, it is impossible to use open flames to cut and clean the impurities from the blocked sprinkler pipes. This greatly increases the difficulty of maintaining the sprinkler pipes and significantly reduces the ease of use and maintenance efficiency of the sprinkler system. Summary of the Invention

[0004] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide a spray device for cooling down hydrogen peroxide concentrate tanks, reducing blockages, and quickly clearing blockages.

[0005] The specific solution of this utility model is: a spray device for cooling, reducing blockage, and quickly clearing hydrogen peroxide concentrate tanks, including a spray pit and a concentrate tank. The spray pit is connected to a main pipe, and the other end of the main pipe is connected to a spray structure. The spray structure includes four branch pipes connected to the main pipe, and the other ends of the four branch pipes are connected to spray pipes. Spray nozzles are opened on the surface of the spray pipes. Cleaning structures are installed at both ends of the spray pipes. The cleaning structure includes fixed blocks installed on both sides. The fixed blocks are rotatably connected to connectors. The other end of the connectors is connected to a sealing cap. Cleaning ports are opened at both ends of the spray pipes and communicate with their interiors. The cleaning ports match the sealing caps. Steps are provided on the inner sidewalls of the cleaning ports. A sealing gasket is provided at one end of the step. A fixing structure is installed on the sealing caps.

[0006] According to the above technical solution, by setting up an easily openable cleaning structure and optimizing the spray layout, the hydrogen peroxide concentrate tank is effectively cooled down, while the spray pipe blockage is reduced and can be quickly cleared, thus improving the safety and ease of maintenance of the device.

[0007] Furthermore, the fixing structure includes a fixing member connected to the sealing cover, which is fixed to the spray pipe by bolts.

[0008] According to the above technical solution, the sealing cover is reliably fixed and easily disassembled by bolting the fastener to the spray pipe, ensuring the sealing performance of the cleaning port and the convenience of the cleaning operation.

[0009] Furthermore, the bottom ends of the four spray pipes are connected to a connecting pipe, which allows the four spray pipes to be interconnected.

[0010] According to the above technical solution, the four spray pipes are interconnected by connecting pipes, which balances the water pressure and flow rate of each pipe, improves the uniformity of spray cooling, and reduces the risk of local blockage.

[0011] Furthermore, the four spray pipes are arranged in a rectangular shape.

[0012] According to the above technical solution, four spray pipes are arranged in a rectangular pattern to ensure uniform spray cooling and improve the overall cooling effect of the tank.

[0013] Furthermore, the spray nozzle is in a straight line shape, which further reduces the risk of clogging.

[0014] According to the above technical solution, the straight spray nozzle design can effectively reduce the accumulation of impurities, further reduce the risk of spray pipe blockage, and ensure smooth spraying.

[0015] Compared with the prior art, this utility model has the following advantages: First, the spray device for cooling, reducing blockage, and quickly clearing the hydrogen peroxide stock solution tank uses a rectangular spray pipe with connecting pipes to achieve balanced water flow and full coverage of the tank. It efficiently cools the tank during high summer temperatures, slows down hydrogen peroxide decomposition, and ensures the safety of stock solution storage. Second, the straight spray nozzle reduces impurity accumulation and prevents blockage, and the cleaning structure at both ends allows for convenient clearing of blockages without open flames, improving the safety and efficiency of blockage clearing. Third, the bolt fixing facilitates the maintenance of the sealing cap, and the connecting pipe reduces local water stagnation and pipe blockage, solving the pain points of traditional systems, reducing maintenance costs, and ensuring a stable supply of stock solution for the hydrogen peroxide desulfurization process.

[0023] See Figure 1-6 This embodiment is a spray device for cooling, reducing blockage, and quickly clearing hydrogen peroxide stock solution tanks. It consists of a spray pit 1 and a stock solution tank 2. The spray pit 1 is connected to a main pipe 3, and the other end of the main pipe 3 is connected to a spray structure. The spray structure includes four branch pipes 4 connected to the main pipe 3. The other end of the four branch pipes 4 is connected to a spray pipe 5. The surface of the spray pipe 5 has spray nozzles 6. Both ends of the spray pipe 5 are equipped with cleaning structures. The cleaning structure includes fixing blocks 7 installed on both sides. The fixing blocks 7 are rotatably connected to connectors 8. The other end of the connectors 8 is connected to a sealing cap 9. Both ends of the spray pipe 5 have cleaning ports 10 that communicate with their interiors. The cleaning ports 10 match the sealing caps 9. The inner wall of the cleaning port 10 has a step 11. One end of the step 11 has a sealing gasket 12. The sealing cap 9 is equipped with a fixing structure.

[0024] Furthermore, the fixing structure includes a fixing member 13 connected to the sealing cover 9. The fixing member 13 is fixed to the spray pipe 5 by bolts 14. Screw holes can be opened on the outer walls of the fixing member 13 and the spray pipe 5, and finally fixed by bolts 14.

[0025] Furthermore, the bottom ends of the four spray pipes 5 are connected to a connecting pipe 15, which allows the four spray pipes 5 to be interconnected.

[0026] Furthermore, the four spray pipes 5 are arranged in a rectangular shape, which further improves the cooling effect.

[0027] Furthermore, the spray nozzle 6 is in a straight line shape, which further reduces the risk of clogging.

[0028] The working principle of this embodiment is as follows: The spray pit 1 serves as the water supply source, delivering cooling water to the main pipe 3. The main pipe 3 then distributes the water flow to four branch pipes 4 connected to it. The four branch pipes 4 correspondingly guide the cooling water into four spray pipes 5 arranged in a rectangular pattern. Simultaneously, the bottom ends of the four spray pipes 5 are interconnected via connecting pipes 15, which balances the water pressure and flow rate within each spray pipe 5, preventing localized water stagnation. Subsequently, the cooling water passes through the straight-line spray nozzles 6 on the surface of the spray pipes 5, utilizing the heat absorption from water evaporation to cool the tank, delaying the decomposition of hydrogen peroxide inside the tank and ensuring the safety of the original solution storage. Due to the opening shape of the straight-line spray nozzles 6, the accumulation of impurities in the water is reduced, lowering the risk of clogging of the spray pipes 5. When the spray pipes 5 become clogged after long-term use, the sealing cap 9 can be removed to secure them. The bolt 14 connecting the fixing part 13 and the spray pipe 5 (the fixing part 13 and the outer wall of the spray pipe 5 have pre-set screw holes) opens the sealing cover 9 by rotating the connector 8 around the fixing block 7, exposing the cleaning ports 10 at both ends of the spray pipe 5 that communicate with the inside (the sealing gasket 12 on the inner step 11 of the cleaning port 10 can ensure the sealing of daily use). The staff cleans the impurities inside the spray pipe 5 through the cleaning port 10. After cleaning, the sealing cover 9 can be closed by reversing the operation. No open flame is required throughout the process, achieving safe and fast unblocking.
