Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and more particularly to a water flow dust removal cyclone cabinet. Background Art

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

[0003] After searching, a vortex double-curtain water curtain cabinet with a publication number of CN104588249B was disclosed, and the publication date was September 2, 2022. This patent achieves a higher paint mist removal effect by setting structures such as vortex plates, upper water troughs, guide plates and water vapor separation plates, and reduces the use of consumables and reduces operating costs. However, in this technical solution, the contact area between the water flow and the dust particles is limited, and the swirl effect of the airflow inside the water curtain cabinet is weak, resulting in low dust adsorption efficiency. In addition, the structure of the equipment is complex. Although the setting of the water vapor separation plate improves the separation effect, it increases the manufacturing cost and maintenance difficulty.

[0004] After searching, a double-inlet water-cyclone water curtain cabinet with a publication number of CN106140545B was disclosed on April 30, 2019. This patent improves the paint mist purification efficiency and facilitates the cleaning of paint residue by setting up double air inlets, a gas-liquid separation chamber and a multi-stage barrier baffle. However, in this technical solution, although the double air inlet design improves the airflow distribution, the intensity of the cyclonic effect is still insufficient, making it difficult to effectively capture fine particles. At the same time, although the setting of the multi-stage barrier baffle enhances the filtering effect, it is also prone to clogging problems, increasing the cleaning frequency and maintenance workload.

[0005] The above problems indicate that existing water curtain cabinets or similar equipment still have certain deficiencies in terms of cyclone effect, water flow and dust contact area, fine particle capture efficiency and equipment maintenance convenience. Summary of the Invention

DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0032] Existing water curtain cabinets or similar equipment still have certain deficiencies in cyclone effect, water flow and dust contact area, fine particle capture efficiency and equipment maintenance convenience. Figure 1 and Figure 2 As shown, the present invention provides a water dust removal cyclone cabinet, and its specific implementation method is as follows: the cabinet body 1 is the main structure of the overall equipment, which is 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 for introducing dust-laden gas; the air outlet 3 is located on the top of the cabinet body 1 for discharging purified gas, the water curtain chamber 4 is communicated with the dust inlet 2, and the air outlet chamber 5 is communicated with the air outlet 3, and the two are connected through several cyclone cylinders 7. The cyclone cylinder 7 is provided with an impeller 8 for generating vortexes to increase the contact area between dust and water, thereby improving the purification efficiency.

[0033] The specific structure of the cyclone cylinder 7 is as follows Figure 2As shown, a baffle plate 9 is provided on the top, and the baffle plate 9 is connected to the impeller part 8 through a cone 10. The small opening end of the cone 10 is connected to the impeller part 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 a number of through holes 11 distributed in an annular manner, allowing gas to pass through and form vortices, further enhancing the cyclone effect. A water outlet nozzle 12 is provided above the cyclone cylinder 7, and the water outlet nozzle 12 is vertically toward the center of the baffle plate 9 and can be extended and retracted in the vertical direction to adjust the water spray range. By adjusting the height of the water outlet nozzle 12, precise control of the spray range can be achieved.

[0034] A water storage tank 13 is provided at the bottom of the cabinet 1, and a reflux port is provided on one side of the water storage tank 13, which is communicated with the water curtain chamber 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 clogging by impurities. A water pump component 15 is provided in the filter tank away from the reflux port. The water pump component 15 is connected to the water outlet nozzle 12 and the water curtain structure through a reflux pipe to ensure the stable operation of the water circulation system. A water level sensor is provided in the filter tank for monitoring the water level. When the water level of the filter tank close to the reflux port is higher than the water level of the filter tank away from the reflux port, it is determined that the barrier net 14 is blocked and a cleaning instruction is triggered.

[0035] The controller is integrated into the cabinet 1 and includes a data acquisition module, a data comparison module, and a parameter adjustment module. The data acquisition module uses a liquid level sensor to collect the water volume value collected at the air outlet 3 over a certain period of time. At the same time, it obtains the current distance value between the bottom of the water outlet nozzle 12 and the center of the baffle 9, the water pressure value of the water outlet nozzle 12, and the suction pressure of the suction structure. Since dust particles will adhere to the surface of the particles after contact with water vapor, the water vapor at the air outlet will be reduced. If the water vapor increases and the water output increases, it means that the adsorption effect is poor. Therefore, the data comparison module compares the collected water volume value with the preset threshold range. If the water volume value is outside the preset threshold range, it outputs an adjustment instruction; otherwise, it outputs a normal instruction. The parameter adjustment module controls the water output of the water curtain structure or the air outlet rate of the air outlet 3 according to the adjustment instruction, and adjusts any one or more parameter values ​​of the distance value, water pressure value, or suction pressure.

[0036] The controller also includes a parameter calculation module for calculating the spraying range based on the distance value, water pressure value and suction wind pressure. The parameter calculation module combines the difference value 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.

[0037] Specifically, the spray range calculation formula can be designed as: Among them, d is the distance between the bottom of the water nozzle and the center of the baffle, P is the water pressure of the water nozzle, F is the suction pressure of the suction structure, R is the spraying range, k1, k2, k3 are the inherent coefficients of the equipment (calibrated through experiments), and the core of the parameter calculation module is to calculate the coverage range of the spray on the baffle (expressed as radius R) based on distance, water pressure, and wind pressure. It reflects the influence of water pressure and distance on the basic range of spraying. The higher the water pressure, the greater the initial velocity of water droplets and the wider the diffusion range. The farther the distance, the longer the water droplets fall and the larger the horizontal diffusion radius. k2·F reflects the enhancement effect of suction wind pressure on the spraying range. The greater the wind pressure, the stronger the airflow carries the water droplets and the wider the coverage. This reflects the correction item used to balance extreme working conditions (such as low water pressure and excessive diffusion over long distances). When the water pressure is too low or the distance is too far, the kinetic energy of the water droplets is insufficient and excessive diffusion will lead to uneven spraying. This item is used to limit ineffective diffusion.

[0038] When the parameter adjustment module needs to adjust 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 spraying radius is R' = R + ΔR. At this time, the adjusted parameters (d', P', F') need to be reversed to meet the following requirements: If you need to increase R' (if the measured water volume is lower than the threshold, you need to expand the spraying range to enhance dust removal), you can fix d and F and adjust the water pressure

[0039]

[0040] The parameter adjustment module in the present invention can dynamically adjust the water output of the water curtain structure or the air outlet rate of the air outlet according to the adjustment instructions output by the data comparison module. When the water volume value collected at the air outlet exceeds the preset threshold range, it indicates that the contact effect between the water flow and the dust in the current dust removal process may be poor (such as excessive water volume resulting in waste of resources, or insufficient water volume resulting in incomplete dust removal). By timely adjusting the relevant parameters, it can ensure that the water flow is fully in contact with the dust-laden gas, improve the dust adsorption efficiency, and ensure that the equipment is always in an efficient dust removal state. In addition, combined with the results of the parameter calculation module, the corresponding correction range can be indexed in the preset matching table according to the difference between the water volume value and the preset threshold, and then adjust the distance value between the water outlet nozzle and the center of the baffle plate, the water pressure value or the suction wind pressure and other parameters. This precise control can match the spraying range with the actual dust removal needs, avoid the errors and lags of manual adjustment, realize the intelligent operation of the equipment, and improve the control accuracy and stability.

[0041] At least one group of spray heads 16 is provided below the impeller member 8. The spray heads 16 can rotate in the vertical direction to adjust the spraying angle, further optimizing the water flow coverage range; the water curtain structure includes a first curved plate 17 and a second curved plate 18. The first curved plate 17 is located below the spray head 16 to guide the water flow to form a water curtain; the second curved plate 18 is located below the first curved plate 17, with its inner curved surface facing the outside of the cabinet 1, forming a dust inlet 2 between the inner curved surface and the water curtain surface, ensuring that the water level is flush with the bottom of the dust inlet 2; the design of the second curved plate 18 enables the dust-laden gas to fully contact the water curtain when entering the water curtain chamber 4, thereby improving the dust adsorption efficiency.

[0042] During actual operation, dust-laden gas enters the water curtain chamber 4 from the dust inlet 2. After passing through the water curtain structure formed by the first curved plate 17 and the second curved plate 18, the dust particles in the gas are initially adsorbed. Subsequently, the gas enters the cyclone barrel 7, where a vortex is formed under the action of the impeller 8, further increasing the contact area between the dust and the water. The vortexed 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 unadsorbed dust particles.

[0043] When the water level sensor in the filter tank detects that the water level of the filter tank near the return port is higher than the water level of the filter tank far away from the return port, the controller determines that the barrier net 14 is blocked and triggers a cleaning instruction. At this time, the parameter adjustment module will reduce the distance value and water pressure value between the water outlet nozzle 12 and the barrier plate 9 to avoid equipment failure due to blockage.

[0044] The water dust removal cyclone cabinet of the present invention is suitable for dust treatment needs in various industrial scenarios; for example, in the furniture manufacturing industry, paint spraying operations will generate a large amount of paint mist and dust. The use of the cyclone cabinet of the present invention can effectively capture these fine particles and improve the air quality in the workshop. In the metal processing industry, the cutting and grinding processes will generate a large amount of metal dust. The present invention can significantly improve the 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 the present invention realize the recycling of water resources, reduce operating costs, and meet the requirements of green production.

[0045] To sum up, the present invention significantly improves the contact area between water flow and dust and the cyclone effect by optimizing the cabinet structure, cyclone cylinder design, control system and spraying system, and enhances the capture efficiency of fine particles. The water curtain chamber 4 in the cabinet 1 is connected to the air outlet chamber 5 through the cyclone cylinder 7, and the vortex generated by the impeller 8 is used to enhance the dust adsorption effect. At the same time, the intelligent design of the controller realizes the dynamic adjustment of the operating parameters, reduces energy consumption and maintenance costs, and the optimized design of the water 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, so that the equipment can maintain an efficient and stable purification effect during actual operation.
