Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a water distributor for waste gas treatment. Background Technology

[0002] Current waste gas treatment typically relies on spraying and water distribution equipment in spray towers. The spraying device evenly sprays liquid into the waste gas, and the harmful substances in the waste gas are absorbed or dissolved by the liquid through gas-liquid contact. This method is widely used in many industries.

[0003] Existing water distribution structures for removing exhaust gas using a single spray method have limited contact time between the exhaust gas and water as the exhaust gas passes through the spray zone, resulting in insufficient removal efficiency of particulate matter and pollutants. Therefore, a water distributor for exhaust gas treatment is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a water distributor for waste gas treatment, which provides a water distribution mechanism with good particulate matter removal effect and high pollutant removal effect for spraying equipment such as spray towers used for waste gas treatment. This allows the waste gas to be filtered by the water mist falling from the spray, while also being filtered by the spray liquid temporarily stored in the gas filtration mechanism, which greatly increases the filtration effect of the waste gas.

[0005] The technical solution adopted by this utility model to solve its technical problem is a water distributor for waste gas treatment, including a spraying mechanism and a filter mechanism for temporarily storing the water falling from the spraying mechanism, wherein the filter mechanism is located at the bottom of the spraying mechanism.

[0006] The spraying mechanism includes a spiral water pipe and a nozzle. At least one set of nozzles is provided and is installed along the bottom of the spiral water pipe at equal intervals with threads, and the spiral water pipe is connected to the water inlet end of the nozzle.

[0007] By adopting the above technical solution, a water distribution mechanism with good particulate matter removal effect and high pollutant removal effect is provided for spraying equipment such as spray towers for waste gas treatment through the components composed of spraying mechanism and air filtration mechanism. This allows the waste gas to be filtered by the water mist falling from the spray and also by the spray liquid temporarily stored in the air filtration mechanism, which greatly increases the filtration effect of waste gas.

[0008] Specifically, the spiral water pipe is connected to support arms at equal intervals around its outer periphery, and a water inlet pipe is inserted into one of the support arms, with the drain end of the water inlet pipe connected to the spiral water pipe.

[0009] By adopting the above technical solution and setting up the support arm, it is possible for personnel to weld and connect it to the inner wall of the spray tower, so that the spiral water pipe can be supported inside the spray tower.

[0010] Specifically, the air filtration mechanism includes a support plate, a partition component, and an overflow sleeve. The partition component is disposed on the inner circumference of the support plate, the overflow sleeve is connected to the center of the support plate, and a drain pipe communicating with the overflow sleeve is connected to the bottom center of the support plate.

[0011] The overflow sleeve has overflow ports at equal intervals on its top outer periphery.

[0012] By adopting the above technical solution, the water sprayed by the spraying mechanism is temporarily stored through the air filtration mechanism, forming a simple water storage tank inside the air filtration mechanism. This allows the exhaust gas to come into contact with the stored water during its passage, forming the first stage of filtration. Excess water inside the air filtration mechanism will be discharged through the overflow port of the overflow sleeve.

[0013] Specifically, the separating component includes an annular sleeve, an annular plate, and a chassis. The annular sleeve has a cavity on its inner wall, the annular plate is inserted into the cavity, and the chassis is welded to the bottom of the annular sleeve. A sealing ring is provided between the chassis and the annular plate.

[0014] By adopting the above technical solution, the spray water is temporarily stored in the water storage area formed between the partition component and the overflow sleeve.

[0015] Specifically, the support plate and the chassis are provided with corresponding air inlets on the bottom outer periphery, the annular sleeve is provided with an exhaust port on the bottom inner periphery, and the annular plate is provided with air inlets at equal intervals on the top for gas to pass through, and the height of the air inlets is higher than the height of the overflow port.

[0016] The beneficial effects of this utility model are as follows: The assembly consisting of a spray mechanism and a filtration mechanism provides a water distribution mechanism with excellent particulate matter removal and high pollutant removal efficiency for spray towers and other spraying equipment used for waste gas treatment. This allows the waste gas to be filtered by the water mist falling from the spray, while also being filtered by the spray liquid temporarily stored in the filtration mechanism, greatly increasing the filtration effect. The combination of the annular sleeve, annular plate, and chassis forms a complex airflow channel. The waste gas first enters the cavity inside the annular sleeve, and then enters the water storage area inside the separator component through the air vents on the annular plate. This not only increases the contact area and time between the waste gas and water, but also improves the removal efficiency. This solves the problem of insufficient particulate matter and pollutant removal efficiency in existing single-spray waste gas removal water distribution structures, where the contact time between the waste gas and water is limited during the passage of the spray area.

Detailed Implementation

[0023] 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.

[0024] like Figure 1-4 As shown, the present invention provides a water distributor for waste gas treatment, which includes a spraying mechanism and a filter mechanism for temporarily storing the water falling from the spraying mechanism. The filter mechanism is located at the bottom of the spraying mechanism.

[0025] The spraying mechanism includes a spiral water pipe 4 and a nozzle 5. At least one set of nozzles 5 are provided and are installed along the bottom of the spiral water pipe 4 at equal intervals with threads, and the spiral water pipe 4 is connected to the water inlet end of the nozzle 5.

[0026] During use, the spraying mechanism and the air filtration mechanism provide a water distribution mechanism for spraying equipment such as spray towers used for waste gas treatment, which has a good particulate matter removal effect and a high pollutant removal effect. This allows the waste gas to be filtered by the water mist falling from the spray, while also being filtered by the spray liquid temporarily stored in the air filtration mechanism, which greatly increases the filtration effect of the waste gas.

[0027] The present invention also includes that the spiral water pipe 4 is connected to support arms 6 at equal intervals on its outer periphery, wherein a water inlet pipe 7 is inserted into one set of support arms 6, and the drain end of the water inlet pipe 7 is connected to the spiral water pipe 4.

[0028] When in use, the support arm 6 helps personnel to weld it to the inner wall of the spray tower, so that the spiral water pipe 4 is supported inside the spray tower.

[0029] The present invention also includes that the air filtration mechanism includes a support plate 1, a dividing component 2 and an overflow sleeve 3. The dividing component 2 is disposed on the inner periphery of the support plate 1, the overflow sleeve 3 is connected to the center of the support plate 1, and a drain pipe 12 communicating with the overflow sleeve 3 is connected to the bottom center of the support plate 1.

[0030] The overflow sleeve 3 has overflow ports 31 at equal intervals on the outer periphery of its top.

[0031] When in use, the air filtration mechanism temporarily stores the water sprayed by the spray mechanism, forming a simple water storage tank inside the air filtration mechanism. This allows the exhaust gas to come into contact with the stored water as it passes through, forming the first stage of filtration. Excess water inside the air filtration mechanism will be discharged through the overflow port 31 of the overflow sleeve 3.

[0032] The present invention also includes that the separating component 2 includes an annular sleeve 26, an annular plate 21 and a base 28. The inner wall of the annular sleeve 26 is provided with a cavity 27, the annular plate 21 is inserted into the cavity 27, the base 28 is welded to the bottom of the annular sleeve 26, and a sealing ring is provided between the base 28 and the annular plate 21.

[0033] During use, the water storage area formed between the separator 2 and the overflow sleeve 3 is used to temporarily store the spray water.

[0034] The present invention also includes that the support plate 1 and the chassis 28 are provided with corresponding air inlets 11 on the outer periphery of the bottom, the annular sleeve 26 is provided with an exhaust port 25 on the bottom of the inner periphery, and the annular plate 21 is provided with air inlets 24 at equal intervals on the top for gas to pass through, and the height of the air inlets 24 is higher than the height of the overflow port 31.

[0035] When in use, the exhaust gas discharged from the bottom of the spray tower will enter the cavity 27 through the air inlet 11. The annular plate 21 separates the inner and outer sides of the cavity 27, so that the gas passes through the air inlet 24 of the annular plate 21 and then enters the water storage area inside the partition component 2 through the exhaust port 25. After contacting the water in the water storage area, it is discharged upward.

[0036] In use, the outer periphery of the support plate 1 and the support arm 6 are welded or bolted to the spray tower or spray equipment for purifying the waste gas. The water supply pipe for supplying liquid to the spray equipment is connected to the inlet pipe 7. After the water source enters the spiral water pipe 4, it is sprayed out by the nozzle 5 at the bottom of the spiral water pipe 4. During the spraying, the water storage area formed between the separation component 2 and the overflow sleeve 3 in the air filtration mechanism temporarily stores the spray water, forming a simple water storage tank in the air filtration mechanism. After the waste gas is discharged at the bottom of the spray equipment, the waste gas will enter the cavity 27 through the air inlet 11. The annular plate 21 separates the inner and outer sides of the cavity 27, so that the gas passes through the air outlet 24 of the annular plate 21 and then enters the water storage area inside the separation component 2 through the exhaust outlet 25. After contacting the water in the water storage area, it is discharged upward and then sprayed out by the water from the nozzle 5 for secondary spray purification treatment. In this way, the waste gas and the purified water source are fully contacted and purified, which improves the efficiency of removing pollutants from the waste gas.
