Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment, and more specifically to a water flow dust removal cyclone cabinet. Background Technology

[0002] With the increasing demand for waste gas and dust treatment in industrial production processes, water-cooled cyclone dust collectors, as a highly efficient purification device, have gradually become a research hotspot in related fields. However, existing water curtain dust collectors or similar equipment still have some shortcomings in structural design and functional implementation, affecting their purification efficiency, energy consumption, and ease of maintenance.

[0003] A search revealed a vortex double-curtain water curtain cabinet with publication number CN104588249B, published on September 2, 2022. This patent achieves a high paint mist removal effect and reduces consumable usage and operating costs by incorporating a vortex plate, upper water tank, guide plate, and water vapor separation plate. However, in this technical solution, the contact area between the water flow and dust particles is limited, and the swirling effect of the airflow inside the water curtain cabinet is weak, resulting in low dust adsorption efficiency. Furthermore, the device has a complex structure; while the water vapor separation plate improves the separation effect, it also increases manufacturing costs and maintenance difficulty.

[0004] A search revealed a dual-inlet water vortex water curtain cabinet with publication number CN106140545B, published on April 30, 2019. This patent improves paint mist purification efficiency and facilitates paint residue cleaning by incorporating dual air inlets, a gas-liquid separation chamber, and multi-stage baffles. However, while the dual air inlet design improves airflow distribution, the intensity of the vortex effect is still insufficient, making it difficult to effectively capture fine particles. Furthermore, while the multi-stage baffles enhance filtration, they can easily lead to clogging, increasing cleaning frequency and maintenance workload.

[0005] The above problems indicate that existing water curtain cabinets or similar equipment still have certain shortcomings in terms of cyclone effect, water flow and dust contact area, fine particle capture efficiency, and ease of equipment maintenance. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a water flow dust removal cyclone cabinet that can solve problems such as poor cyclone effect, small dust contact area, low fine particle capture efficiency, high energy consumption, and inconvenient maintenance of existing equipment. By optimizing the structure and water circulation design, the purification efficiency and stability are improved, and the cost is reduced.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A water-flow dust removal cyclone cabinet includes a cabinet body with a dust inlet and an air outlet. The cabinet body contains a dust removal chamber and a water curtain structure. The dust removal chamber includes two independent water curtain chambers and an air outlet chamber. The water curtain chambers are connected to the dust inlet, and the air outlet chambers are connected to the air outlet. A plurality of cyclone cylinders are provided between the water curtain chambers and the air outlet chambers, and the cyclone cylinders connect the water curtain chambers and the air outlet chambers. Each cyclone cylinder contains an impeller for generating vortices.

[0009] Furthermore, the impeller is located at the bottom of the cyclone cylinder, and the top of the cylinder is also provided with a baffle plate for sealing the cylinder port. A cone is provided between the baffle plate and the impeller. One end of the cone with a small opening is connected to the impeller, and one end of the cone with a large opening is connected to the baffle plate. The diameter of the large opening of the cone is smaller than the diameter of the baffle plate. The baffle plate is provided with a number of through holes distributed in a ring. A water nozzle is provided above the cyclone cylinder.

[0010] Furthermore, the water nozzle is vertically oriented towards the center of the barrier plate, and the water nozzle can extend and retract in the vertical direction to adjust the spray range of the water nozzle.

[0011] Furthermore, the bottom of the cabinet is provided with a water storage tank, and a return port communicating with the water curtain cavity is provided on one side of the water storage tank. At least one barrier net is provided in the water storage tank, which divides the water storage tank into several filter tanks. A water pump is provided in the filter tank away from the return port. The water pump is connected to the water nozzle and the water curtain structure through a return pipe.

[0012] Furthermore, at least one set of spray heads is provided below the impeller component, and the spray heads can rotate in the vertical direction to adjust the spray angle of the spray heads.

[0013] Furthermore, the water curtain structure includes a first arc-shaped plate located below the spray head.

[0014] Furthermore, the water curtain structure also includes a second arc-shaped plate, the side of the cabinet is the water curtain surface, the second arc-shaped plate is located below the first arc-shaped plate, the inner arc surface of the second arc-shaped plate faces the outside of the cabinet, and a gap is provided between the second arc-shaped plate and the water curtain surface to form a dust inlet, and the water level at the bottom of the cabinet is at least flush with the bottom of the dust inlet.

[0015] The beneficial effects of this utility model are as follows: by optimizing the cabinet structure, cyclone cylinder design, control system and spraying system, the contact area between water flow and dust and the cyclone effect are significantly improved, the capture efficiency of fine particles is enhanced, the water curtain chamber and the air outlet chamber inside the cabinet are connected through the cyclone cylinder, and the dust adsorption effect is enhanced by the vortex generated by the impeller. The optimized design of the water storage tank and the filtration system realizes the recycling of water resources and reduces resource waste.

[0016] In addition, through specific structural design and parameter adjustment mechanism, the shortcomings of existing equipment in terms of purification efficiency, energy consumption and maintenance convenience have been solved.

[0021] Existing water curtain cabinets or similar equipment still have certain shortcomings in terms of cyclone effect, water-dust contact area, fine particle capture efficiency, and ease of maintenance. Figure 1 and Figure 2 As shown, this utility model provides a water flow dust removal cyclone cabinet, the specific implementation of which is as follows: the cabinet body 1 is the main structure of the overall equipment, with a box-type design, and has multiple functional areas inside, including a water curtain chamber 4, an air outlet chamber 5 and a water storage tank 13. The dust inlet 2 is located on the side of the cabinet body 1 and is used to introduce dust-laden gas; the air outlet 3 is located on the top of the cabinet body 1 and is used to discharge the purified gas. The water curtain chamber 4 is connected to the dust inlet 2, and the air outlet chamber 5 is connected to the air outlet 3. The two are connected by several cyclone cylinders 7. The cyclone cylinders 7 are equipped with impeller components 8, which are used to generate vortices to enhance the contact area between dust and water, thereby improving the purification efficiency.

[0022] The specific structure of the cyclone cylinder 7 is as follows: Figure 2As shown, a baffle plate 9 is provided on the top of the device. The baffle plate 9 is connected to the impeller 8 through a cone 10. The small opening end of the cone 10 is connected to the impeller 8, and the large opening end is connected to the baffle plate 9, forming a gradually expanding structure to optimize the airflow distribution. The baffle plate 9 is provided with several through holes 11 arranged in a ring to allow gas to pass through and form a vortex, further enhancing the cyclone effect. A water nozzle 12 is provided above the cyclone cylinder 7. The water nozzle 12 is vertically oriented towards the center of the baffle plate 9 and can extend and retract in the vertical direction to adjust the spray range. By adjusting the height of the water nozzle 12, precise control of the spray range can be achieved.

[0023] The bottom of the cabinet 1 is equipped with a water storage tank 13. A return port is provided on one side of the water storage tank 13, which is connected to the water curtain cavity 4 to realize the recycling of water resources. At least one barrier net 14 is provided in the water storage tank 13 to divide the water storage tank 13 into multiple filter tanks to prevent impurities from clogging. A water pump 15 is provided in the filter tank away from the return port. The water pump 15 is connected to the water outlet nozzle 12 and the water curtain structure through the return pipe to ensure the stable operation of the water circulation system. A water level sensor is provided in the filter tank to monitor the water level. When the water level in the filter tank near the return port is higher than the water level in the filter tank away from the return port, it is determined that the barrier net 14 is blocked and a cleaning command is triggered.

[0024] The controller is integrated into cabinet 1 and includes a data acquisition module, a data comparison module, and a parameter adjustment module. The data acquisition module collects the water volume value collected at the air outlet 3 over a certain period of time through a liquid level sensor. At the same time, it acquires the distance between the bottom of the water nozzle 12 and the center of the baffle plate 9, the water pressure value of the water nozzle 12, and the suction pressure of the suction structure. Since dust particles will adhere water to the surface of the particles after contact with water vapor, thereby reducing the water vapor at the air outlet, if the water vapor increases and the water volume increases, it indicates that the adsorption effect is not good. Therefore, the data comparison module compares the collected water volume value with a preset threshold range. If the water volume value is outside the preset threshold range, an adjustment command is output; otherwise, a normal command is output. The parameter adjustment module controls the water volume of the water curtain structure or the air outlet speed of the air outlet 3 according to the adjustment command, and adjusts any one or more of the following parameter values: distance value, water pressure value, or suction pressure.

[0025] The controller also includes a parameter calculation module, which calculates the spraying range based on the distance value, water pressure value, and suction air pressure. The parameter calculation module combines the difference with the correction range corresponding to the preset matching table index, calculates and adjusts the relevant parameter values ​​based on the correction range and the spraying range, thereby achieving precise control of the spraying system.

[0026] Specifically, the formula for calculating the spraying range can be designed as follows: Where d is the distance between the bottom of the water nozzle and the center of the baffle plate, P is the water pressure of the water nozzle, F is the suction pressure of the suction structure, R is the spraying range, and k1, k2, and k3 are the inherent coefficients of the equipment (calibrated experimentally). The core of the parameter calculation module is to calculate the coverage area (represented by radius R) sprayed on the baffle plate by using distance, water pressure, and air pressure. The effect of water pressure and distance on the spraying range is reflected in the following parameters: higher water pressure results in greater initial droplet velocity and a wider diffusion range; greater distance leads to longer droplet fall time and a larger horizontal diffusion radius. k²·F reflects the enhancing effect of suction wind pressure on the spraying range; higher wind pressure results in stronger water droplet carrying capacity and a wider coverage area. The correction term is used to balance excessive diffusion under extreme conditions (such as low water pressure or long distance). When the water pressure is too low or the distance is too far, the water droplet kinetic energy is insufficient, and excessive diffusion will lead to uneven spraying. This term limits ineffective diffusion.

[0027] When the parameter adjustment module needs to adjust the parameters based on the water volume difference (ΔQ = measured water volume - preset threshold), combined with the correction range (ΔR) in the preset matching table, the target spray radius is R' = R + ΔR. At this time, it is necessary to reverse-calculate the adjusted parameters (d', P', F') to satisfy: If R' needs to be increased (e.g., if the measured water volume is below the threshold, the spraying range needs to be expanded to enhance dust removal), d and F can be fixed, and the water pressure adjusted.

[0028]

[0029] In this invention, the parameter adjustment module can dynamically adjust the water flow rate of the water curtain structure or the air outlet velocity based on the adjustment instructions output by the data comparison module. When the water volume collected at the air outlet exceeds the preset threshold range, it indicates that the contact effect between the water flow and dust in the current dust removal process may be poor (e.g., excessive water leading to resource waste, or insufficient water leading to incomplete dust removal). By adjusting the relevant parameters in a timely manner, it can ensure that the water flow and dust-laden gas are in full contact, improve dust adsorption efficiency, and ensure that the equipment is always in a highly efficient dust removal state. In addition, based on the results of the parameter calculation module, the difference between the water volume and the preset threshold can be used to index the corresponding correction range in the preset matching table, thereby adjusting parameters such as the distance between the water nozzle and the center of the baffle plate, the water pressure, or the suction air pressure. This precise control allows the spraying range to match the actual dust removal needs, avoiding the errors and lags of manual adjustment, realizing intelligent operation of the equipment, and improving control accuracy and stability.

[0030] At least one set of spray heads 16 is provided below the impeller component 8. The spray heads 16 can rotate in the vertical direction to adjust the spray angle and further optimize the water flow coverage. The water curtain structure includes a first arc plate 17 and a second arc plate 18. The first arc plate 17 is located below the spray heads 16 and guides the water flow to form a water curtain. The second arc plate 18 is located below the first arc plate 17, with its inner arc surface facing the outside of the cabinet 1. It forms a dust inlet 2 with the water curtain surface, ensuring that the water level is flush with the bottom of the dust inlet 2. The design of the second arc plate 18 allows the dust-laden gas to fully contact the water curtain when it enters the water curtain cavity 4, thereby improving the dust adsorption efficiency.

[0031] In actual operation, dust-laden gas enters the water curtain chamber 4 through the dust inlet 2. After passing through the water curtain structure formed by the first arc plate 17 and the second arc plate 18, the dust particles in the gas are initially adsorbed. Subsequently, the gas enters the cyclone cylinder 7, where it forms a vortex under the action of the impeller 8, further increasing the contact area between the dust and water. The vortex gas enters the air outlet chamber 5 through the through hole 11 on the baffle plate 9 and is finally discharged from the air outlet 3. During this process, the water nozzle 12 continuously sprays water onto the baffle plate 9, forming a water curtain to further capture any unadsorbed dust particles.

[0032] When the water level sensor in the filter tank detects that the water level in the filter tank near the return port is higher than the water level in the filter tank far from the return port, the controller determines that the barrier screen 14 is blocked and triggers a cleaning command. At this time, the parameter adjustment module will reduce the distance and water pressure between the water nozzle 12 and the barrier plate 9 to avoid equipment failure due to blockage.

[0033] This utility model's water-flow dust removal cyclone cabinet is suitable for dust treatment needs in various industrial scenarios. For example, in the furniture manufacturing industry, painting operations generate a large amount of paint mist and dust. Using this utility model's cyclone cabinet can effectively capture these fine particles and improve workshop air quality. In the metal processing industry, cutting and grinding processes generate a large amount of metal dust. This utility model can significantly improve dust adsorption efficiency and reduce environmental pollution by optimizing the cyclone effect and water flow coverage. In addition, the water storage tank 13 and filtration system design of this utility model realize the recycling of water resources, reduce operating costs, and meet the requirements of green production.

[0034] In summary, this utility model significantly improves the contact area and cyclone effect between water flow and dust by optimizing the cabinet structure, cyclone cylinder design, control system, and spraying system, thereby enhancing the capture efficiency of fine particles. The water curtain chamber 4 and the air outlet chamber 5 inside the cabinet 1 are connected through the cyclone cylinder 7, and the vortex generated by the impeller component 8 enhances the dust adsorption effect. At the same time, the intelligent design of the controller enables dynamic adjustment of operating parameters, reducing energy consumption and maintenance costs. The optimized design of the water storage tank 13 and the filtration system realizes the recycling of water resources and reduces resource waste. The flexible adjustment function of the spraying system further improves the adaptability and stability of the equipment, enabling the equipment to maintain a highly efficient and stable purification effect in actual operation.
