Description

A spray tower dust mist removal device Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology, specifically a dust removal device for spray towers and water mist. Background Technology

[0002] Spray towers are common industrial waste gas treatment equipment, widely used in flue gas dust removal and gas purification. These devices remove harmful substances through the contact adsorption of dust particles by the spray liquid. For example, a flue gas dust removal and purification device with publication number CN111298559B, published on November 15, 2024, uses multiple absorption spray towers installed in series, along with a foaming mechanism and a spraying mechanism, to effectively adsorb and remove impurities from the flue gas. However, this device still has some limitations in practical applications. Because it uses a traditional foaming adsorption method, the binding efficiency of the spray liquid and dust may be limited in high humidity or high temperature environments, thus affecting the overall dust removal effect. Furthermore, this setup does not incorporate a dynamic adjustment function for the spray liquid, which may lead to water waste or unstable dust removal performance. To optimize these issues, a design with an external water tank is proposed, facilitating maintenance and allowing dust washing to directly enter the water tank, avoiding the need for internal tower cleaning. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model provides a spray tower dust mist removal device. The technical implementation of this utility model is as follows: A spray tower dust mist removal device includes a treatment tower, an external water tank, a flow guiding component, an adjustment mechanism, a spray head assembly, and a filter screen. The treatment tower has one component. A flow guiding component is located at the bottom of the treatment tower and is fixedly connected to the inner wall of the treatment tower. The flow guiding component is arranged at an angle to guide the dust washing liquid to the outside. An external water tank is located on one side of the treatment tower and is connected to the bottom of the treatment tower via a pipe to receive the washing liquid flowing out from the flow guiding component. An adjustment mechanism is located at the top of the treatment tower and is fixedly connected to the inner wall of the treatment tower to dynamically adjust the flow rate of the spray liquid. A spray head assembly is installed inside the treatment tower and is connected to the adjustment mechanism via a hose to achieve uniform distribution of the spray liquid. A filter screen is located at the air inlet of the treatment tower and is embedded in the inner wall of the treatment tower to intercept larger particles.

[0004] Optionally, the flow guiding assembly includes a flow guiding plate and flow guiding channels. The flow guiding plate is fixedly installed on the bottom inner wall of the treatment tower. Multiple flow guiding channels are opened on the surface of the flow guiding plate. The flow guiding channels are arranged along the inclined direction of the flow guiding plate to accelerate the liquid flow.

[0005] Optionally, the regulating mechanism includes a regulating valve, a drive rod, and limit blocks. The regulating valve is installed at the top of the treatment tower. The input end of the regulating valve is connected to the hose of the spray head assembly, and the output end is connected to the water supply pipe of the treatment tower. A drive rod is installed in the middle of the regulating valve. The drive rod passes through the housing of the regulating valve and extends to the outside to manually or automatically control the valve opening. Limit blocks are installed at both ends of the drive rod to limit the movement range of the drive rod.

[0006] Optionally, it also includes a distributor and nozzles. Each nozzle in the spray head assembly is equipped with a distributor. The input end of the distributor is connected to a hose, and the output end is connected to multiple nozzles to distribute the spray liquid evenly to each nozzle. The outlet end of the nozzle is tapered to increase the diffusion area of ​​the spray liquid.

[0007] Optionally, it also includes a detection module and a feedback unit. The detection module is installed on the side wall of the treatment tower. The sensor probe of the detection module extends into the interior of the treatment tower to monitor the flow rate of the spray liquid and the dust concentration in real time. The output end of the detection module is connected to the feedback unit, which is installed outside the treatment tower to adjust the working state of the regulating mechanism according to the detection results.

[0008] Optionally, it also includes a cleaning brush and a drive shaft. The cleaning brush is provided on the inner side of the filter screen, and the bristles of the cleaning brush are in contact with the surface of the filter screen. A drive shaft is provided in the middle of the cleaning brush. The drive shaft 15 passes through the side wall of the treatment tower and is connected to an external motor to drive the cleaning brush to rotate and remove the dust accumulated on the filter screen.

[0009] Optionally, a sedimentation chamber and an overflow pipe are provided inside the external water tank. The sedimentation chamber is located at the bottom of the external water tank and is used to collect solid particles in the washing liquid. One end of the overflow pipe is connected to the sedimentation chamber, and the other end extends to the outside of the external water tank to drain excess liquid.

[0010] Optionally, multiple baffles are provided on the inner wall of the treatment tower, and the baffles are distributed in a stepped manner to prolong the residence time of flue gas in the treatment tower; the surface of the baffles is coated with a hydrophobic coating to reduce liquid residue.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] This utility model provides a dust removal device for a spray tower using water mist, the structure and operating principle of which are described in detail with reference to Figures 1 to 3. As shown in Figure 1, the device includes a treatment tower 1, an external water tank 2, an adjustment mechanism 4, a spray head assembly 5, a filter screen 6, and a motor 9.

[0023] Implementation Case 1

[0024] In this embodiment, the treatment tower 1 is the core component of the entire device, and its internal space is used to accommodate the mixing process of dust and spray liquid. A flow guiding assembly 3 is installed at the bottom of the treatment tower 1, the specific structure of which is shown in Figure 2. The flow guiding assembly 3 includes a guide plate 7 and flow channels 8. The guide plate 7 is fixedly installed on the inner wall of the bottom of the treatment tower 1, and multiple flow channels 8 are formed on its surface. These flow channels 8 are arranged along the inclined direction of the guide plate 7, allowing the washing liquid to flow rapidly. This arrangement ensures that the washing liquid can flow smoothly into the external water tank 2, avoiding the cumbersome operation of frequently cleaning the bottom of the tower in traditional setups.

[0025] The external water tank 2 is connected to the bottom of the treatment tower 1 via a pipe and is used to receive the washing liquid flowing out from the guide assembly 3. As shown in Figure 1, the external water tank 2 is located on one side of the treatment tower 1, and it has a sedimentation chamber and an overflow pipe inside. The sedimentation chamber is located at the bottom of the external water tank 2 and is used to collect solid particles in the washing liquid, while one end of the overflow pipe is connected to the sedimentation chamber and the other end extends to the outside of the external water tank 2 to drain excess liquid. This configuration not only optimizes the recycling of the washing liquid but also reduces maintenance costs.

[0026] Therefore, an adjustment mechanism 4 is installed at the top of the treatment tower 1, as shown in the figure. The adjustment mechanism 4 includes an adjustment valve 10, a drive rod 11, and limit blocks 12. The input end of the adjustment valve 10 is connected to the hose of the spray head assembly 5, and the output end is connected to the water supply pipe of the treatment tower 1. A drive rod 11 is installed in the middle of the adjustment valve 10, which passes through the housing of the adjustment valve 10 and extends to the outside, for manual or automatic control of the valve opening. Limit blocks 12 are installed at both ends of the drive rod 11 to limit the range of movement of the drive rod 11. By setting up the adjustment mechanism 4, the flow rate of the spray liquid can be dynamically adjusted to adapt to the dust removal requirements under different working conditions.

[0027] With this configuration, the spray head assembly 5 is installed inside the treatment tower 1, as shown in Figure 4. The spray head assembly 5 is connected to the regulating mechanism 4 via a flexible hose. Each spray head is equipped with a distributor 13, the input end of which is connected to the flexible hose, and the output end of which is connected to multiple nozzles 14. The outlet end of the nozzles 14 is tapered to increase the diffusion area of ​​the spray liquid. The combined use of the distributor 13 and the nozzles 14 ensures that the spray liquid can uniformly cover the internal space of the treatment tower 1, improving the contact efficiency between the spray liquid and dust particles.

[0028] It should also be noted that a filter screen 6 is installed at the air inlet of the treatment tower 1. The filter screen 6 is embedded in the inner wall of the treatment tower 1 to intercept larger particles. A cleaning brush 16 is installed inside the filter screen 6, with the bristles of the cleaning brush 16 in contact with the surface of the filter screen 6. A drive shaft 15 is installed in the middle of the cleaning brush 16, which passes through the side wall of the treatment tower 1 and is connected to an external motor 9 to drive the cleaning brush 16 to rotate and remove the dust accumulated on the filter screen 6. This design effectively solves the problem of the filter screen 6 easily becoming clogged after long-term use.

[0029] In addition, multiple layers of baffles are installed on the inner wall of treatment tower 1, arranged in a stepped pattern, to extend the residence time of flue gas within the tower. The surfaces of the baffles are coated with a hydrophobic coating to reduce liquid residue. This arrangement further improves the contact time and efficiency between dust and the spray liquid.

[0030] To monitor the flow rate of the spray liquid and the dust concentration in real time, a detection module is installed on the side wall of the treatment tower 1, with the sensor probe of the detection module extending into the interior of the treatment tower 1. The output of the detection module is connected to a feedback unit, which is installed outside the treatment tower 1 and is used to adjust the working state of the regulating mechanism 4 based on the detection results. This setup ensures that the device can dynamically adjust its operating parameters according to actual working conditions.

[0031] During actual operation, dust-laden gas enters through the inlet of treatment tower 1 and first passes through filter screen 6 to intercept larger particles. Subsequently, the gas comes into full contact with the spray liquid ejected from the spray head assembly 5 inside treatment tower 1, and the dust is captured by the spray liquid to form a washing liquid. The washing liquid flows along the guide plate 7 and the guide channel 8 of the flow guiding assembly 3 into the external water tank 2, where solid particles are deposited in the sedimentation chamber, and excess liquid is discharged through the overflow pipe. During operation, the regulating mechanism 4 dynamically adjusts the flow rate of the spray liquid based on feedback signals from the detection module to ensure optimal dust removal efficiency. Simultaneously, the cleaning brush 16, driven by the drive shaft 15, periodically removes dust accumulated on the filter screen 6, ensuring long-term stable operation of the equipment.

[0032] Through the coordinated operation of the above-mentioned components, this utility model achieves efficient and stable dust treatment function, while significantly reducing water waste and maintenance costs.

[0033] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.

[0034] First, when dust-laden gas enters the inlet of the treatment tower 1, it first passes through the filter screen 6. The filter screen 6 is embedded in the inner wall of the treatment tower 1 to intercept larger particles. A cleaning brush 16 is installed on the inner side of the filter screen 6, with its bristles in close contact with the surface of the filter screen 6. The cleaning brush 16 is connected to an external motor via a drive shaft 15. When the dust accumulation on the surface of the filter screen 6 reaches a certain thickness, the external motor 9 drives the drive shaft 15 to rotate, causing the cleaning brush 16 to remove the accumulated dust from the filter screen 6. This design effectively solves the problem of poor gas flow caused by filter screen clogging in traditional spray towers. Regular cleaning of the accumulated dust ensures the long-term efficient operation of the filter screen 6 and maintains the uniformity of gas entering the treatment tower 1.

[0035] Subsequently, the gas enters the interior of the treatment tower 1 and comes into full contact with the spray liquid ejected from the spray head assembly 5. The spray head assembly 5 is installed inside the treatment tower 1, and its structure is shown in the figure. Each spray head is equipped with a distributor 13, the input end of which is connected to a hose, and the output end is connected to multiple nozzles 14. The outlet end of the nozzles 14 is tapered to increase the diffusion area of ​​the spray liquid. The combined use of the distributor 13 and the nozzles 14 ensures that the spray liquid can uniformly cover the interior space of the treatment tower 1. This configuration significantly improves the contact efficiency between the spray liquid and dust particles, thereby enhancing the dust removal effect. In addition, the flow rate of the spray liquid is dynamically adjusted by the regulating mechanism 4. As shown in the figure, the regulating mechanism 4 includes a regulating valve 10, a drive rod 11, and a limit block 12. The input end of the regulating valve 10 is connected to the hose of the spray head assembly 5, and the output end is connected to the water supply pipe of the treatment tower 1. The drive rod 11 passes through the housing of the regulating valve 10 and extends to the outside, for manual or automatic control of the valve opening. Limit block 12 restricts the movement range of drive rod 11, ensuring that the opening of regulating valve 10 is always within a reasonable range. The flow rate of spray liquid and dust concentration are monitored in real time by the detection module, and the data is fed back to the feedback unit. The feedback unit adjusts the working state of regulating mechanism 4 according to the detection results, thereby achieving precise control of spray liquid flow rate.

[0036] Multiple layers of baffles are installed on the inner wall of treatment tower 1, arranged in a stepped pattern to extend the residence time of flue gas within the tower. The surfaces of the baffles are coated with a hydrophobic coating to reduce liquid residue. This arrangement further improves the contact time and efficiency between dust and the spray liquid. Guided by the baffles, the flue gas flows along a stepped path, increasing its contact opportunities with the spray liquid and thus enhancing the dust removal effect.

[0037] Next, the sprayed liquid captures dust to form a washing liquid, which flows into the external water tank 2 along the flow guiding assembly 3. As shown in the figure, the flow guiding assembly 3 includes a flow guiding plate 7 and flow channels 8. The flow guiding plate 7 is fixedly installed on the bottom inner wall of the treatment tower 1, and multiple flow channels 8 are formed on its surface. These flow channels 8 are arranged along the inclined direction of the flow guiding plate 7, allowing the washing liquid to flow quickly. This design ensures that the washing liquid can flow smoothly into the external water tank 2, avoiding the cumbersome operation of frequently cleaning the bottom of the tower in traditional settings.

[0038] An external water tank 2 is connected to the bottom of the treatment tower 1 via a pipe and is used to receive the washing liquid flowing out from the guide assembly 3. As shown in Figure 1, the external water tank 2 is located on one side of the treatment tower 1, and its interior is equipped with a sedimentation chamber and an overflow pipe. Solid particles in the washing liquid are deposited in the sedimentation chamber, and excess liquid is discharged through the overflow pipe. The sedimentation chamber not only optimizes the recycling of the washing liquid but also reduces maintenance costs. The introduction of the external water tank 2 avoids the cumbersome operation of cleaning inside the tower required in traditional setups, significantly improving the maintenance efficiency of the equipment.

[0039] During actual operation, all components work together to ensure the efficient and stable operation of the device. For example, when the detection module detects that the dust concentration is too high, the feedback unit will adjust the working state of the regulating mechanism 4 according to the detection results, increasing the flow rate of the spray liquid to improve the dust removal effect. At the same time, the cleaning brush 16, driven by the drive shaft 15, periodically removes the dust accumulated on the filter screen 6, ensuring the long-term stable operation of the equipment.

[0040] Through the detailed explanation of the above steps, it can be seen that this utility model achieves a highly efficient and stable dust treatment function through the coordinated work of various components, while significantly reducing water waste and maintenance costs. The above description is merely a preferred embodiment of this utility model and is not intended to limit it. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
