Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment, and in particular to a dust removal device for waste gas treatment. Background Technology

[0002] In industrial production, waste gas treatment is undoubtedly a crucial link in ensuring air quality, maintaining the ecological environment, and protecting human health. However, with the acceleration of industrialization, the problem of fine particulate matter emissions in waste gas is becoming increasingly serious. Like an invisible killer, they are silently eroding our breathing environment, posing a huge threat to air quality, ecological balance, and even human health.

[0003] To address this serious challenge, various traditional waste gas treatment technologies, including baghouse dust collectors, have been implemented, but they prove inadequate when dealing with fine particulate matter that is difficult to capture. In particular, existing water mist dust collection technology, despite attempts to improve dust collection efficiency by enhancing the contact between water mist and waste gas, often encounters problems of insufficient contact and uneven distribution in practice. For example, simple water spray devices struggle to ensure uniform coverage of the entire waste gas flow space, resulting in inconsistent dust collection performance; while complex spray systems are often difficult to scale up due to high energy consumption and cumbersome maintenance. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a waste gas treatment and dust removal device that increases the contact time and area between water mist and waste gas, making the contact between water mist and waste gas more sufficient and uniform, thereby improving the collection and treatment efficiency of fine particulate matter in waste gas.

[0006] To achieve the above objectives, this utility model proposes a waste gas treatment and dust removal device, comprising a water tank, a dust collection box, a spiral plate, and multiple atomizing nozzles.

The bottom surface of the spiral plate is connected to the shell, and the top surface of the spiral plate abuts against the sealing cover. The atomizing nozzles are disposed on the inner bottom surface of the shell, and multiple atomizing nozzles are spirally distributed along the spiral plate. The atomizing nozzles are connected to the water tank.

[0007] The exhaust gas treatment and dust removal device of this utility model increases the contact time and area between water mist and exhaust gas, making the contact between water mist and exhaust gas more sufficient and uniform, thereby improving the collection and treatment efficiency of fine particulate matter in exhaust gas.

[0008] In addition, the exhaust gas treatment and dust removal device proposed in the application may also have the following additional technical features:

[0010] Specifically, the bottom surface of the shell is provided with multiple seepage holes, and the shell and the water tank are connected through the seepage holes.

[0011] Specifically, the spiral plate has a pile layer on both sides.

[0012] Specifically, the housing is further provided with a plurality of guide components, which are distributed in a spiral shape along the spiral plate; the guide components include a hinge shaft, a compression spring and two movable plates; the hinge shaft is mounted on the inner bottom surface of the housing, the two movable plates are hinged to the hinge shaft and are located on the same side of the hinge shaft; the two ends of the compression spring are respectively connected to the opposite surfaces of the two movable plates, and the ends of the two movable plates away from the hinge shaft respectively abut against the spiral plate.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The waste gas treatment and dust removal device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the exhaust gas treatment and dust removal device of this utility model embodiment may include a water tank 10, a dust removal box 20, a spiral plate 30, and a plurality of atomizing nozzles 40.

[0024] Water tank 10 contains water.

[0025] The dust collector 20 is located above the water tank 10, and the dust collector 20 includes a housing 21 and a sealing cover 22.

[0026] The housing 21 is mounted on the water tank 10, and the sealing cover 22 is sealed on the opening on the top surface of the housing 21.

[0027] An air inlet 23 is provided on the side wall of the housing 21, and an air outlet 24 is provided on the top surface of the sealing cover 22.

[0028] It should be noted that the air inlet 23 and the air outlet 24 are connected to the air inlet pipe and the air extraction pipe (not shown in the figure) respectively. The exhaust gas enters the dust collector 20 from the air inlet 23, and the gas after dust removal is discharged from the air outlet 24.

[0029] The spiral plate 30 is spirally arranged inside the housing 21, with the air inlet 23 facing the outer end of the spiral plate 30 and the air outlet 24 facing the inner end of the spiral plate 30, so that the exhaust gas can flow along the spiral plate 30 inside the housing 21 after passing through the air inlet 23, and then be discharged through the air outlet 24.

[0030] The bottom surface of the spiral plate 30 is connected to the inner bottom surface of the housing 21, and the top surface of the spiral plate 30 is in contact with the sealing cover 22.

[0031] It should be noted that the pitch and number of turns of the spiral plate 30 are selected according to the actual situation, and will not be detailed here.

[0032] The atomizing nozzle 40 is disposed on the inner bottom surface of the housing 21, and multiple atomizing nozzles 40 are distributed in a spiral shape along the spiral plate 30.

[0033] The atomizing nozzle 40 is connected to the water tank 10, so that the water inside the water tank 10 can be sprayed into the housing 21 through the atomizing nozzle 40.

[0034] It should be noted that the atomizing nozzles 40 and the spiral plate 30 are staggered. There can be 10, 11, 12, 13, 14 atomizing nozzles 40, etc. The specific number is selected according to actual needs, which will not be detailed here.

[0035] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figure 2 As shown, a water pump 11 is installed inside the water tank 10. The input end of the water pump 11 extends to the bottom of the water tank 10, and the output end of the water pump 11 is connected to a water collection pipe 12.

[0036] It should be noted that the water tank 10 is equipped with a water injection valve and a drain valve. The water injection valve and the drain valve are existing technologies and will not be described in detail here.

[0037] The water collection pipe 12 is a spiral water pipe, and multiple atomizing nozzles 40 pass through the housing 21 and are connected to the water collection pipe 12.

[0038] It should be noted that the water collection pipe 12 is made of rigid material, which makes the atomizing nozzle 40 more stable during the atomization and spraying of water.

[0039] Specifically, during actual operation, relevant personnel inject an appropriate amount of water into the water tank 10 through the water injection valve, check whether the connections of each component are tight, and ensure that there is no leakage; start the water pump 11, so that the water in the water tank 10 is transported to each atomizing nozzle 40 through the water collection pipe 12; at the same time, start the air inlet pipe and the air extraction pipe connected to the air inlet end 23 and the air outlet end 24, so that the exhaust gas begins to enter the dust collection box 20. The exhaust gas enters the dust collection box 20 from the air inlet end 23 and flows along the path of the spiral plate 30. The atomized water sprayed by the atomizing nozzle 40 comes into full contact with the exhaust gas, adsorbing and settling the dust particles in the exhaust gas; the treated clean gas is discharged from the air outlet end 24.

[0040] Using water atomization to treat exhaust gas eliminates the need for chemical agents, reducing the risk of secondary pollution; the atomized water can be recycled, saving water resources; and the exhaust gas, guided by the spiral plate 30, has a longer path, increasing the contact time and area with the atomized water, thereby improving dust removal efficiency.

[0041] Furthermore, in one embodiment of this utility model, such as Figure 3 As shown, the bottom surface of the shell 21 has multiple seepage holes 211, and the shell 21 and the water tank 10 are connected through the seepage holes 211.

[0042] It should be noted that there may be 6, 7, 8, 9, or 10 seepage holes 211, and the specific number can be selected according to actual needs, which will not be detailed here.

[0043] It should be noted that the distribution location and diameter of the seepage holes 211 are selected according to actual needs, and will not be described in detail here.

[0044] Understandably, a certain amount of water will accumulate in the dust collection box 20 over time, but this water will flow back into the water tank 10 through the seepage hole 211 on the bottom surface of the shell 21; the water in the water tank 10 will be drawn out again by the water pump 11 and transported to the atomizing nozzle 40 through the water collection pipe 12 for recycling.

[0045] The water seepage hole 211 allows the water in the dust collector 20 to automatically flow back into the water tank 10, avoiding water waste and improving water utilization. It also prevents the problem of reduced dust removal efficiency caused by excessive water accumulation in the dust collector 20, ensuring the stability and efficiency of the device under different operating conditions. Because water recycling is achieved, the frequency of replacing new water is reduced, thereby reducing operating and maintenance costs.

[0046] In one embodiment of this utility model, such as Figure 5 As shown, the spiral plate 30 has a pile layer 31 on both sides.

[0047] It should be noted that the pile layer 31 is distributed in a spiral shape along the spiral plate 30, and the pile layer 31 can be set on the spiral plate 30 by Velcro.

[0048] Understandably, after the exhaust gas enters the dust collector 20 from the inlet 23, it flows along the path of the spiral plate 30. At this time, the atomized water sprayed by the atomizing nozzle 40 not only comes into direct contact with the exhaust gas, but also wets the fluff layer 31 on both sides of the spiral plate 30. A water film forms on the surface of the wetted fluff layer 31, which enhances its ability to adsorb dust. When the exhaust gas passes through the fluff layer 31, the dust particles in it are adhered to and captured by the water film on the fluff layer 31. Over time, more and more dust accumulates on the fluff layer 31, but due to the replaceability of the fluff layer 31, the dust removal effect can be restored by replacing the fluff layer 31.

[0049] The addition of the fluff layer 31 increases the contact area and adhesion between the exhaust gas and the dust removal medium, thereby improving the dust removal efficiency. The replaceability of the fluff layer 31 allows the equipment to quickly restore the dust removal effect when needed, thus extending the maintenance cycle.

[0050] Furthermore, in one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the housing 21 is also provided with a plurality of guide components 50, and the guide components 50 are distributed in a spiral shape along the spiral plate 30.

[0051] It should be noted that there can be 4, 5, 6, 7, or 8 boot components 50, etc. The specific number is selected according to actual needs, which will not be detailed here.

[0052] The guide assembly 50 includes a hinge shaft 51, a compression spring 53, and two movable plates 52.

[0053] The hinge shaft 51 is vertically mounted on the inner bottom surface of the housing 21, and two movable pieces 52 are hinged to the hinge shaft 51, with the two movable pieces 52 located on the same side of the hinge shaft 51.

[0054] It should be noted that the two movable pieces 52 are hinged to the hinge shaft 51. This hinge method can be referred to as the hinge method of door hinges, which is existing technology and will not be described in detail here.

[0055] It should be noted that after the exhaust gas enters the housing 21, the included angle formed by the two movable plates 52 is in the same direction as the flow direction of the exhaust gas.

[0056] The two ends of the compression spring 53 are respectively connected to the opposite surfaces of the two movable plates 52, and the ends of the two movable plates 52 away from the hinge shaft 51 respectively abut against the spiral plate 30.

[0057] It should be noted that the spring constant of compression spring 53 is selected according to actual needs, which will not be detailed here.

[0058] Understandably, after the exhaust gas enters the housing 21 from the inlet 23, it first encounters the guide component 50. Since the angle formed by the two movable plates 52 is aligned with the flow direction of the exhaust gas after entering the housing 21, the exhaust gas pushes the movable plates 52 to rotate around the hinge shaft 51. Simultaneously, the compression spring 53 provides a certain restoring force, allowing the movable plates 52 to adhere tightly to the spiral plate 30 and maintain a certain angle, thereby guiding the exhaust gas along the shape of the spiral plate 30. During this flow, the exhaust gas comes into full contact with the fluff layer 31 and the atomized water. The fluff layer 31, after being moistened, adsorbs dust, while the atomized water further encapsulates and settles the dust particles. The presence of the guide component 50 not only improves the contact efficiency between the exhaust gas and the dust removal medium but also makes the flow of the exhaust gas more orderly and stable, which is beneficial for improving the dust removal effect.

[0059] The guiding component 50 can guide the exhaust gas to flow along the shape of the spiral plate 30, increasing the contact opportunities and time between the exhaust gas and the fluff layer 31 and the atomized water, thereby improving the dust removal efficiency; through the combined action of the movable plate 52 and the compression spring 53, the guiding component 50 can automatically adapt to the exhaust gas treatment requirements of different flow rates and concentrations, maintaining the stable operation of the equipment.

[0060] In summary, the exhaust gas treatment and dust removal device of this utility model increases the contact time and area between water mist and exhaust gas, making the contact between water mist and exhaust gas more sufficient and uniform, thereby improving the collection and treatment efficiency of fine particulate matter in exhaust gas.
