Description

Technical Field

[0001] The present application relates to the field of waste gas spray towers, and in particular to a cyclone hybrid spray tower. Background Art

[0002] The cyclone hybrid spray tower is a device used to treat industrial waste gas. Its main function is to adsorb harmful substances in the discharged waste gas, thereby purifying the waste gas and protecting the environment and human health. Waste gas purification equipment is widely used in the treatment of industrial waste gas in the chemical, metallurgical, electric power, petroleum, pharmaceutical and other industries.

[0003] In the related technology, such as publication number CN214715531U, a waste gas spray tower includes a tower body 1. The tower body is a cylindrical cavity structure. A demisting layer, a packing layer one, a packing layer two and an air bin are arranged in sequence from top to bottom in the tower body. An air inlet and an air outlet are respectively opened on one side of the air bin and the top of the tower body. The packing layer one and the packing layer two are respectively provided with a material replacement device for replacing the packing in the packing layer one and the packing layer two. A spray device is provided above the packing layer one and the packing layer two for spraying to form water mist. A water supply device is provided next to the tower body for supplying water to the spray device. The waste gas enters from the air inlet and passes through the air bin, the packing layer two, the packing layer one and the demisting layer in sequence. The purified gas is finally discharged from the outlet.

[0004] Regarding the above-mentioned related technologies, there is a defect that the exhaust gas moves in a straight line in the spray tower, so the flow speed of the exhaust gas is fast, and the contact area and contact time between the exhaust gas and the spray water are small, which leads to the poor exhaust gas purification ability of the spray tower. Summary of the invention

[0005] In order to improve the exhaust gas purification capacity of the spray tower, the present application provides a cyclone hybrid spray tower.

[0006] The cyclone hybrid spray tower provided in this application adopts the following technical solution: A cyclone hybrid spray tower, comprising: The processing box is provided with an air inlet and an air outlet, an air flow channel is provided between the air inlet and the air outlet, and the air flow channel is extended in a serpentine shape; The spray components are distributed along the extension direction of the air flow channel.

[0007] By adopting the above technical solution, since the air flow channel is extended in a serpentine shape, the air flow will pass through the air flow channel in a tortuous manner, and the flow velocity of the exhaust gas will be reduced, so the contact area between the exhaust gas and the spray water will be larger, and the contact time between the exhaust gas and the spray water will be longer, which will help to improve the exhaust gas purification capacity of the spray tower. In addition, compared with the method of directly increasing the height of the spray tower, this design method does not need to increase the height of the spray tower while increasing the exhaust gas treatment time, thereby making the spray tower smaller in size for easy assembly and transportation.

[0008] Preferably, the treatment box includes an inlet water washing tank and a water rotary barrel, the upper end of the inlet water washing tank is connected to the air inlet, and the inlet water washing tank is provided with the spray assembly; the upper end of the water rotary barrel is connected to the lower end of the inlet water washing tank, and the cross-sectional area of ​​the water rotary barrel is smaller than the cross-sectional area of ​​the inlet water washing tank, so as to allow the gas to pass through the reduced flow section to produce a Venturi effect.

[0009] By adopting the above technical solution, a large amount of waste gas can be initially washed with water when it enters the inlet water washing tank. When the waste gas enters the water cyclone from the inlet water washing tank, the Venturi effect caused by the reduction of the flow end surface will accelerate the airflow to collide with the spray water. At the same time, the airflow will also flow in a spiral to separate the pollutants from the air, so that the pollutants can better contact with the spray water. Therefore, the waste gas can be more fully washed with water, thereby improving the waste gas purification capacity without increasing the water consumption.

[0010] Preferably, the upper end of the water rotary barrel penetrates the lower wall of the inlet water washing bin, and the part of the water rotary barrel in the inlet water washing bin is threadedly connected with a mounting bolt, and a plurality of the mounting bolts are distributed around the center of the water rotary barrel, and the rod of the mounting bolt abuts against the lower wall of the inlet water washing bin, so as to change the distance between the upper end edge of the water rotary barrel and the lower wall of the inlet water washing bin.

[0011] By adopting the above technical solution, firstly, the upper edge of the water cyclone barrel will be higher than the lower wall of the inlet water washing bin, so the water falling to the lower wall of the inlet water washing bin needs to accumulate to a certain depth before flowing into the water cyclone barrel, so that more water can contact the exhaust gas in the water cyclone barrel, thereby increasing the contact area between the exhaust gas and the spray water; secondly, because the exhaust gas flows in a spiral manner in the water cyclone barrel, the setting method of the mounting bolts can keep the upper end of the water cyclone barrel flat, so that water flows in from different positions of the upper edge of the water cyclone barrel, thereby maintaining the water washing adsorption capacity for the exhaust gas.

[0012] Preferably, an extension plate and a diffuser mesh plate are provided at the lower end of the water rotary barrel, the upper end of the extension plate is connected to the lower end of the water rotary barrel, and the lower end of the extension plate is connected to the diffuser mesh plate, and a plurality of the extension plates are spaced apart around the center of the water rotary barrel to form a ventilation window.

[0013] By adopting the above technical solution, the gas can leave the vertical area where the water cyclone is located from the ventilation window, and the water will pass through the diffuser mesh and be broken up into water mist again, so the exhaust gas will be washed and adsorbed again, thereby maintaining the smoothness of gas passage while improving the exhaust gas purification capacity.

[0014] Preferably, the treatment box also includes a water collecting bin, an outlet water washing bin and a defogger bin, the upper end of the water collecting bin is connected to the lower end of the water rotary barrel; the lower end of the outlet water washing bin is connected to the upper end of the water collecting bin, and the outlet water washing bin is provided with the spray assembly; the lower end of the defogger bin is connected to the upper end of the outlet water washing bin, and the upper end of the defogger bin is connected to the air outlet.

[0015] By adopting the above technical scheme, firstly, the movement path of the gas is U-shaped, so that the air intake and outlet are at the top, but the spray waste water will accumulate at the bottom, so it is convenient to reprocess the spray waste water without affecting the gas flow, and it is also convenient for the external fan equipment to be used in conjunction with the spray tower; secondly, the gas passes through the demisting chamber from bottom to top, and the water mist in the gas can be better removed under the combined action of the bent pipe structure in the demisting chamber and the gravity of the water, so that the gas leaving the spray tower can be drier.

[0016] Preferably, a cyclone tray is provided in the outlet water washing bin, and the blades of the cyclone tray are arranged at an angle to apply a rotational force around the ascending direction to the gas.

[0017] By adopting the above technical solution, due to the setting of the cyclone tray, the exhaust gas will move upward in a spiral after passing through the cyclone tray, so that the pollutants can be better contacted with the spray water, thereby allowing the exhaust gas to be more fully washed.

[0018] Preferably, a water tank box is further included, wherein the water tank box is arranged below the treatment tank, the water tank box is connected to the lower end of the water collection bin, and a circulation component is arranged between the water tank box and the spray component.

[0019] By adopting the above technical solution, the water in the water collection bin can flow into the water tank for accumulation to prevent waste water from blocking the channel between the water rotary barrel and the outlet water washing bin, while cooperating with the circulation component to achieve the purpose of circulating water.

[0020] Preferably, the circulation component is divided into an external circulation part and an internal circulation part. The external circulation part is used to send sewage into an external treatment water tank and return it to the spray component after purification; the internal circulation part connects the water tank and the spray component through a structure combining a pump and a pipeline.

[0021] By adopting the above technical scheme, the internal circulation can maintain the responsiveness of the circulating water of the spray tower, and the external circulation can maintain the cleanliness of the circulating water of the spray tower, thereby reducing the working requirements of the equipment supporting the spray tower while maintaining the purification performance of the spray tower.

[0022] Preferably, the water pool box is provided with a partition plate, an inner overflow bucket, an outer overflow bucket and a filter net, the partition plate is used to divide the water pool box into an outer storage bin and an inner storage bin, the outer storage bin is connected to the water collecting bin, the outer storage bin is connected to the outer circulation part, the inner storage bin is connected to the inner circulation part, and the partition plate is provided with a connecting port; the inner overflow bucket is connected to the partition plate, the inner overflow bucket is connected to the connecting port, and is used to allow sewage to flow from the outer storage bin into the inner storage bin by overflow; the outer overflow bucket is arranged in the outer storage bin, the outer overflow bucket is connected to the outer circulation part, and the overflow height of the outer overflow bucket is greater than the overflow height of the inner overflow bucket; the filter net is arranged in the inner storage bin, and is used to filter the sewage flowing into the inner circulation part.

[0023] By adopting the above technical scheme, when the wastewater enters the external storage bin, the liquid level of the wastewater in the external storage bin will gradually rise. When the liquid level of the wastewater exceeds the height of the internal overflow bucket, the wastewater in the external storage bin will flow into the internal storage bin. The wastewater flowing into the internal storage bin will enter the internal circulation part after passing through the filter to realize internal circulation water use. When the liquid level of the wastewater exceeds the height of the external overflow bucket, the wastewater in the external storage bin will flow into the external circulation part to realize external circulation water use. In summary, the ratio between the internal circulation water use and the external circulation water use can be balanced by the size of the connecting port and the height difference between the external overflow bucket and the internal overflow bucket, thereby improving the performance of the spray tower while simplifying the structural form of the spray tower.

[0024] Preferably, a plurality of support beams are provided between the water pool box and the treatment box, and the plurality of support beams are spaced apart to form a water pool window between the water pool box and the treatment box; the filter screen is arranged at an angle, the lower end of the filter screen is located in the internal storage bin, the upper end of the filter screen is exposed in the water pool window, the filter screen is push-pull mounted on the internal storage bin along its own inclination direction, and the filter screen is arranged in multiple layers stacked in parallel in its own inclination direction.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: Because the airflow channel is set in a serpentine extension, the airflow will pass through the airflow channel in a zigzag flow, and the flow speed of the exhaust gas will be reduced, so the contact area between the exhaust gas and the spray water will be larger, and the contact time between the exhaust gas and the spray water will be longer, which will help to improve the exhaust gas purification capacity of the spray tower. In addition, compared with the method of directly raising the height of the spray tower, this design method increases the exhaust gas treatment time while the height of the spray tower does not need to be raised, so that the volume of the spray tower is smaller, which is convenient for assembly and transportation; When the wastewater enters the external storage bin, the liquid level of the wastewater in the external storage bin will gradually rise. When the liquid level of the wastewater exceeds the height of the internal overflow bucket, the wastewater in the external storage bin will flow into the internal storage bin. The wastewater flowing into the internal storage bin will enter the internal circulation part after passing through the filter to realize internal circulation water use. When the liquid level of the wastewater exceeds the height of the external overflow bucket, the wastewater in the external storage bin will flow into the external circulation part to realize external circulation water use.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a cyclone hybrid spray tower. Figure 1 and Figure 2 The cyclone hybrid spray tower includes a treatment box 1 and a spray assembly 2. The treatment box 1 is provided with an air inlet 11 and an air outlet 12. An air flow channel 13 is provided between the air inlet 11 and the air outlet 12, and the air flow channel 13 is extended in a serpentine shape; the spray assembly 2 is distributed along the extension direction of the air flow channel 13, and the specific distribution number is determined according to the length of the air flow channel 13. In the process of the air flow passing through the air flow channel 13 in a bending flow manner, the flow velocity of the exhaust gas will be reduced, so the contact area between the exhaust gas and the spray water will be larger, and the contact time between the exhaust gas and the spray water will be longer, which will help to improve the exhaust gas purification capacity of the spray tower. In addition, the height of the spray tower does not need to be increased, thereby making the volume of the spray tower smaller, which is convenient for assembly and transportation.

[0035] Reference Figure 1 and Figure 2 In this embodiment, in order to take into account the structural simplicity of the spray tower, the air flow channel 13 has only one bend. In one of the straight parts of the air flow channel 13, the treatment box 1 will include an inlet water washing bin 3 and a water rotary barrel 4. The upper end of the inlet water washing bin 3 is connected to the air inlet 11, and the inlet water washing bin 3 is provided with a spray assembly 2 to play the role of the first water washing adsorption; the water rotary barrel 4 is in a circular tube shape, and the upper end of the water rotary barrel 4 is connected to the lower end of the inlet water washing bin 3. The cross-sectional area of ​​the water rotary barrel 4 is smaller than the cross-sectional area of ​​the inlet water washing bin 3. When the gas passes through the reduced flow section, a Venturi effect will be generated, and then the air flow will accelerate to collide with the spray water. At the same time, the air flow will also spirally flow to separate the pollutants from the air, so that the pollutants can better contact with the spray water, so the exhaust gas can be more fully washed, thereby improving the exhaust gas purification capacity without additional water consumption.

[0036] Reference Figure 2 and Figure 3In order to allow the waste gas to contact with water more fully in the water cyclone 4, the following settings are correspondingly arranged: the upper end of the water cyclone 4 is penetrated by the lower wall of the inlet water washing bin 3, and the upper end edge of the water cyclone 4 is higher than the lower wall of the inlet water washing bin 3. The water on the lower wall of the inlet water washing bin 3 needs to accumulate to a certain depth before flowing into the water cyclone 4, so that more water in the water cyclone 4 can contact with the waste gas to increase the contact area between the waste gas and the spray water. In order to realize the aforementioned connection structure, the water cyclone 4 is located in a part of the spiral of the inlet water washing bin 3. The groove is connected with mounting bolts 41, and multiple mounting bolts 41 are evenly distributed around the center of the water rotary barrel 4. The rod of each mounting bolt 41 abuts against the lower wall of the inlet water washing bin 3. The mounting bolts 41 can be rotated to change the distance between the upper edge of the water rotary barrel 4 and the lower wall of the inlet water washing bin 3, so as to level the upper edge of the water rotary barrel 4. Therefore, water can flow into the water rotary barrel 4 evenly from all sides, so that the exhaust gas moving spirally downward can evenly contact with the spray water, thereby maintaining sufficient water washing of the exhaust gas.

[0037] Reference Figure 2 and Figure 3 After leaving the water cyclone 4, the exhaust gas will enter the bend of the air flow channel 13. In order to maintain the smoothness of the exhaust gas, an extension plate 42 and a diffuser mesh plate 43 are provided at the lower end of the water cyclone 4. The extension plate 42 is in the shape of a long thin plate, and the diffuser mesh plate 43 is in the shape of a cylindrical thin plate. Specifically, the upper end of the extension plate 42 is fixedly connected to the lower end of the water cyclone 4, and the lower end of the extension plate 42 is fixedly connected to the diffuser mesh plate 43. A plurality of extension plates 42 are distributed around the center of the water cyclone 4 at intervals, and a ventilation window 44 is formed between two adjacent extension plates 42. The gas can leave the vertical area where the water cyclone 4 is located from the ventilation window 44, and the water will pass through the diffuser mesh plate 43 and be broken into water mist again, so the exhaust gas will be washed and adsorbed again, thereby maintaining the smoothness of the gas passage while improving the exhaust gas purification capacity.

[0038] Reference Figure 2 , at the bend of the air flow channel 13 and the remaining straight part, the treatment box 1 includes a water collecting bin 5, an outlet water washing bin 6 and a defogger bin 7 in sequence. The upper end of the water collecting bin 5 is connected to the lower end of the water rotary barrel 4, the lower end of the outlet water washing bin 6 is connected to the upper end of the water collecting bin 5, the outlet water washing bin 6 is provided with a spray assembly 2, the lower end of the defogger bin 7 is connected to the upper end of the outlet water washing bin 6, the upper end of the defogger bin 7 is connected to the air outlet 12, and the defogger bin 7 will remove the water mist in the gas through the bent pipeline structure and the gravity of the water. In summary, it can be seen that the airflow moves downward first, then turns, and then moves upward. At the same time, the air intake and outlet are both at the top, and the spray wastewater accumulates at the bottom, so it will not affect the exhaust gas from entering or leaving the spray tower, and it is also convenient for the external fan equipment to be used in conjunction with the spray tower. In addition, the spray wastewater is concentrated at the bottom, which is also convenient for subsequent treatment.

[0039] Reference Figure 2 and Figure 4 In order to make the gas do spiral motion in the part where the exhaust gas moves straight upward, a cyclone tray 61 is provided in the outlet water washing bin 6. The blades of the cyclone tray 61 are inclined to apply a rotational force to the gas around the upward direction. Therefore, the exhaust gas will move upward in a spiral after passing through the cyclone tray 61, so that the pollutants can better contact with the spray water, so that the exhaust gas can be more fully washed. In summary, the gas will spirally move in both straight parts, thereby achieving better purification of the exhaust gas on a shorter gas movement path.

[0040] Reference Figure 1 and Figure 2 Since the exhaust gas will pass through the water collecting tank 5, in order to maintain the smoothness of the exhaust gas, the waste water cannot stay in the water collecting tank 5 for too long, and the spray tower also includes a pool box 8, which is arranged below the treatment tank 1, and the pool box 8 is connected to the lower end of the water collecting tank 5. A circulation component 9 is arranged between the pool box 8 and the spray component 2, wherein in order to consider the responsiveness of the circulating water and the cleanliness of the circulating water, the circulation component 9 is divided into an external circulation part 91 and an internal circulation part 92, and the external circulation part 91 will send the sewage into the external treatment water pool box 8, and send it back to the spray component 2 after purification to realize external circulation water supply, and the internal circulation part 92 will connect the pool box 8 and the spray component 2 through a structure combining a pump and a pipeline to realize internal circulation water supply, thereby maintaining the purification performance of the spray tower while reducing the working requirements of the equipment supporting the spray tower.

[0041] Reference Figure 1 and Figure 5 In order to achieve a corresponding proportion of wastewater flowing into the internal circulation part 92 and the external circulation part 91, the following settings are correspondingly arranged: a partition plate 81, an internal overflow bucket 82, an external overflow bucket 83 and a filter screen 84 are arranged in the water pool box 8, and the partition plate 81 is fixedly connected to the inner wall of the water pool box 8. The partition plate 81 will divide the water pool box 8 into an external storage bin 85 and an internal storage bin 86 distributed on the left and right. The external storage bin 85 is connected to the water collection bin 5. After leaving the water collection bin 5, the wastewater will enter the external storage bin 85. The external storage bin 85 is connected to the external circulation part 91, and the internal storage bin 86 is connected to the internal circulation part 92. The partition plate 81 is provided with a connecting port 811 to allow the wastewater in the external storage bin 85 to enter the internal storage bin 86.

[0042] Reference Figure 1 and Figure 5The inner overflow bucket 82 is connected to the partition plate 81, and the inner overflow bucket 82 is located on the side of the partition plate 81 close to the internal storage bin 86. The inner overflow bucket 82 is connected to the connecting port 811, and the sewage will flow from the external storage bin 85 into the internal storage bin 86 by overflow. The outer overflow bucket 83 is arranged in the external storage bin 85, and the outer overflow bucket 83 is connected to the external circulation part 91. The overflow height of the outer overflow bucket 83 is greater than the overflow height of the inner overflow bucket 82; the filter screen 84 is arranged in the internal storage bin 86, and the waste water will flow into the internal circulation part 92 only after passing through the filter screen 84, so as to properly keep the internal circulation water clean.

[0043] Reference Figure 1 and Figure 5 The specific diversion process of wastewater is as follows. When the wastewater enters the external storage bin 85, the liquid level of the wastewater in the external storage bin 85 will gradually rise. When the liquid level of the wastewater exceeds the height of the internal overflow bucket 82, the wastewater in the external storage bin 85 will flow into the internal storage bin 86. The wastewater flowing into the internal storage bin 86 will enter the internal circulation part 92 again after passing through the filter screen 84 to realize internal circulation water use. When the liquid level of the wastewater exceeds the height of the external overflow bucket 83, the wastewater in the external storage bin 85 will flow into the external circulation part 91 to realize external circulation water use. In summary, the ratio between the internal circulation water use and the external circulation water use can be balanced by the size of the connecting port 811 and the height difference between the external overflow bucket 83 and the internal overflow bucket 82, thereby improving the performance of the spray tower while simplifying the structural form of the spray tower.

[0044] Reference Figure 1 and Figure 5 In order to facilitate the cleaning of the water pool box 8 and the filter screen 84, the following settings are correspondingly arranged: a plurality of support beams 14 are arranged between the water pool box 8 and the treatment box 1, and the plurality of support beams 14 are distributed at intervals, and each support beam 14 is connected to a corner on the upper side of the water pool box 8, so the water pool box 8 is not completely closed, and a water pool window 15 is formed between the water pool box 8 and the treatment box 1, and the filter screen 84 will be installed tilted to increase the filtering area, wherein the lower end of the filter screen 84 is in the internal storage bin 86, and the upper end of the filter screen 84 is exposed in the water pool window 15. Specifically, a filter screen 84 will be equipped with two U-shaped channel steel structure tracks, and the two ends of the filter screen 84 will be slidably embedded in this track respectively, so that the filter screen 84 can be pushed and pulled on the internal storage bin 86 along its own tilt direction. In addition, in order to be able to perform maintenance work synchronously when the spray tower is working, the filter screen 84 is stacked in parallel with its own tilt direction. Multiple layers are arranged.

[0045] In other embodiments, if it is considered whether the filter screen 84 is easy to install and disassemble, the structural form of the pool window 15 also needs to be considered. For example, if the horizontal area of ​​the pool box 8 is larger than the treatment box 1, the filter screen 84 can also be vertically installed in the area where the pool box 8 is not blocked by the treatment box 1 in the vertical direction.

[0046] The implementation principle of a cyclone hybrid spray tower in an embodiment of the present application is as follows: because the airflow channel 13 is arranged to extend in a serpentine shape, the airflow will pass through the airflow channel 13 in a bent flow manner, and the flow velocity of the exhaust gas will be reduced, so the contact area between the exhaust gas and the spray water will be larger, and the contact time between the exhaust gas and the spray water will be longer, which will help to improve the exhaust gas purification capacity of the spray tower. In addition, compared with the method of directly increasing the height of the spray tower, this design method, while increasing the exhaust gas treatment time, does not need to increase the height of the spray tower, thereby making the volume of the spray tower smaller, which is convenient for assembly and transportation.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
