Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device. Background Art

[0002] Exhaust gas treatment equipment primarily refers to environmental protection equipment that utilizes various technologies to reduce harmful components in exhaust gases, thereby purifying the air and protecting the environment. Currently, exhaust gas treatment equipment typically includes independent pretreatment and exhaust devices, used to treat acidic, alkaline, organic, or toxic exhaust gases. However, these exhaust gas treatment systems have a low degree of integration and occupy a large area, which limits their application environments.

[0003] Therefore, how to improve the integration level of exhaust gas treatment equipment to reduce the equipment's footprint has become a difficult problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] The utility model provides an exhaust gas treatment device, which is used to improve the integration level of the exhaust gas treatment device, thereby reducing the floor space occupied by the exhaust gas treatment device.

[0005] The utility model provides an exhaust gas treatment device, comprising a housing, an exhaust gas treatment unit, and an exhaust fan. The exhaust gas treatment unit is located within the housing and divides the housing into a first chamber and a second chamber adjacent to each other, the first chamber and the second chamber being connected via the exhaust gas treatment unit. The housing comprises an air inlet and an air outlet, the air inlet being connected to the first chamber, and the air outlet being connected to the second chamber. The exhaust fan is located in the second chamber, with the exhaust fan's outlet facing the air outlet.

[0006] With the exhaust gas treatment equipment provided by the present invention, since the induced draft fan is directly located within the second chamber, it can avoid the induced draft fan from occupying additional space outside the housing. This improves the integration of the exhaust gas treatment equipment while effectively reducing the floor space of the exhaust gas treatment equipment. Furthermore, since the air outlet of the induced draft fan located in the second chamber faces the air outlet of the housing, during the exhaust gas treatment process, the air pressure in the first chamber can be greater than that in the second chamber, which helps improve gas flow efficiency, thereby effectively improving the efficiency of exhaust gas purification and discharge.

[0007] In one possible implementation of the present invention, since the air inlet of the induced draft fan faces the exhaust gas treatment unit, during the exhaust gas treatment process, the clean gas purified by the exhaust gas treatment unit can directly enter the induced draft fan through the air inlet of the induced draft fan. Furthermore, since the air outlet of the housing is located on the side of the induced draft fan facing away from the exhaust gas treatment unit, and the air outlet of the induced draft fan faces the air outlet, the clean gas blown out of the air outlet of the induced draft fan can be directly discharged to the outside of the housing through the air outlet of the housing. This can effectively shorten the flow path of the clean gas, thereby facilitating improved purification efficiency of the exhaust gas treatment equipment.

[0008] In one possible implementation of the present invention, the exhaust gas treatment equipment includes multiple induced draft fans, and the sum of the projected areas of the air inlets of the multiple induced draft fans on the exhaust gas treatment unit is greater than the projected area of ​​the air inlet of a single induced draft fan on the exhaust gas treatment unit. This allows the multiple induced draft fans to blow clean air, purified by the exhaust gas treatment unit, toward the outlet, effectively improving the flow efficiency of the airflow.

[0009] In one possible implementation of the present invention, the diameter of the induced draft fan's air outlet is larger than the diameter of the air outlet. This effectively reduces the risk of air from outside the enclosure flowing back into the enclosure, and allows the clean air blown out of the induced draft fan's air outlet to directly cover the entire air outlet and be blown out through the outlet. This helps improve the flow efficiency of the clean air to the outside of the enclosure and further enhances the purification efficiency of the equipment.

[0010] In one possible implementation of the present invention, the distance between the air outlets of the induced draft fan is L, and L satisfies the following conditions: 0 mm ≤ L ≤ 1000 mm. This effectively reduces the volume of the box while ensuring airflow efficiency, thereby reducing the equipment's manufacturing cost and footprint.

[0011] In one possible implementation of the present invention, the exhaust gas treatment device further includes a mounting frame, the mounting frame being located in the second chamber and fixedly connected to the side wall of the housing, and the induced draft fan being disposed on the mounting frame. The exhaust gas treatment device provided by the present invention, because the mounting frame is fixedly connected to the side wall of the housing and the induced draft fan is disposed on the mounting frame, facilitates improving the reliability of the connection between the induced draft fan and the housing.

[0012] In one possible implementation of the present invention, the mounting bracket includes a support and a vibration-damping structure. The support is fixedly connected to the side wall of the housing. The vibration-damping structure is located between the support and the induced draft fan, with one side of the vibration-damping structure connected to the support and the other side to the induced draft fan. This prevents a rigid connection between the induced draft fan and the housing, thereby reducing the risk of damage to the induced draft fan due to vibration during transportation or operation of the exhaust gas treatment equipment.

[0013] In one possible implementation of the present invention, the mounting bracket is located between the induced draft fan and the exhaust gas treatment unit, with the support fixedly connected to the side wall of the housing. This satisfies the mounting bracket's requirement to support the induced draft fan along the direction of gravity, and because the exhaust gas treatment device occupies a relatively small area, it can be applied in a wide range of scenarios.

[0014] In one possible implementation of the present invention, the support comprises a fixed portion and a hollow portion, the fixed portion being connected to the side wall of the housing, and the vibration-damping structure being disposed on the fixed portion. Therefore, the support can provide stable support for the induced draft fan while also facilitating airflow through the hollow portion and out of the air outlet, thereby improving the purification efficiency of the device.

[0015] In one possible implementation of the present invention, the mounting bracket is positioned between the fan and the side wall of the housing, with the support fixedly connected to the side wall of the housing on the side facing away from the exhaust fan. This satisfies the mounting bracket's requirement to support the exhaust fan along the direction of gravity, and because the exhaust gas treatment device occupies a relatively small area, it can be applied in a wide range of scenarios.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be understood as being limited to the embodiments described herein. The same figure marks in the figures represent the same or similar structures, and thus their repeated descriptions will be omitted. The words expressing position and direction described in the embodiments of the present invention are all explained using the accompanying drawings as examples, but changes can be made as needed, and the changes made are all included in the scope of protection of the present invention. The drawings of the embodiments of the present invention are only used to illustrate the relative position relationship, and they do not represent the true proportions.

[0021] It should be noted that the following description sets forth specific details to facilitate understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art may make similar generalizations without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] With the continuous development of industrialization, the types and emissions of industrial waste gas are also increasing, generally including acidic waste gas, alkaline waste gas, organic waste gas or toxic waste gas, etc. In order to reduce the pollution level of the above waste gas to the environment, the waste gas needs to be purified by waste gas treatment equipment before it is discharged. Among them, the purification method of waste gas treatment equipment mainly refers to the use of different process technologies to reduce the harmful components in the waste gas to achieve the purpose of protecting the environment and purifying the air. At present, waste gas treatment equipment generally includes independent waste gas pretreatment devices and gas emission devices, etc., for treating acidic waste gas, alkaline waste gas or organic waste gas or toxic waste gas, etc. However, the above-mentioned waste gas treatment equipment has a low degree of integration and occupies a large area, which limits the application of waste gas treatment equipment.

[0023] In view of this, the waste gas treatment equipment provided by the present invention is used to reduce the equipment's footprint by improving its degree of integration. In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the exhaust gas treatment equipment provided by the present invention. It shows the placement of the exhaust gas treatment equipment in actual use. Specifically, the exhaust gas treatment equipment includes a housing 1, an exhaust gas treatment unit 2, and a draft fan 3.

[0025] The exhaust gas treatment unit 2 is located inside the housing 1 , and the exhaust gas treatment unit 2 divides the housing 1 into a first chamber 01 and a second chamber 02 that are adjacent to each other, and the first chamber 01 and the second chamber 02 are communicated through the exhaust gas treatment unit 2 .

[0026] When specifically configuring the housing 1, the housing 1 includes an air inlet 11 and an air outlet 12. The air inlet 11 communicates with the first chamber 01, and the air outlet 12 communicates with the second chamber 02. This allows exhaust gas to enter the first chamber 01 of the housing 1 through the air inlet 11, and then the clean gas obtained after purification by the exhaust gas treatment unit 2 enters the second chamber 02 and is discharged through the air outlet 12.

[0027] As can be seen from the above description, the exhaust gas treatment unit 2 is used to purify the exhaust gas. The present invention does not limit the specific form of the exhaust gas treatment unit 2. For example, Figure 1 As shown, the exhaust gas treatment unit 2 includes a filtrate net 21 and a spraying device 22, wherein the spraying device 22 is close to the first chamber 01 relative to the filtrate net 21, so as to spray the exhaust gas treatment liquid into the exhaust gas so that the exhaust gas and the exhaust gas treatment liquid undergo a chemical reaction, thereby achieving the purpose of purifying the exhaust gas.

[0028] When the spray device 22 is specifically set, continue to refer to Figure 1 The spray device 22 may include a nozzle mounting frame 221 and a plurality of nozzles 222. The nozzle mounting frame 221 is fixedly connected to the side wall of the housing 1. The nozzle mounting frame 221 and the housing 1 may be fixedly connected by welding to improve the reliability of the connection between the nozzle mounting frame 221 and the housing 1. In addition, the plurality of nozzles 222 are arranged in an array, and the openings of the plurality of nozzles 222 are all facing the first chamber 01. In this way, the exhaust gas treatment liquid can be directly sprayed through the nozzles 222 into the exhaust gas in the first chamber 01, thereby improving the purification efficiency of the exhaust gas treatment equipment.

[0029] exist Figure 1 In the illustrated embodiment, the exhaust gas treatment equipment may also include a liquid storage tank 5 for storing the exhaust gas treatment liquid. Specifically, the liquid storage tank 5 is located in the first chamber 01 and is spaced from the spray device 2 along the direction from the second chamber 02 to the first chamber 01, and abuts the inner wall of the housing 1. This further enhances the integration of the exhaust gas treatment equipment. Furthermore, a circulation pump 23 is provided between the liquid storage tank 5 and the nozzle 222 to circulate the exhaust gas treatment liquid between the liquid storage tank 5 and the nozzle 222.

[0030] In addition, when the filtrate net 21 is specifically set up, the edge of the filtrate net 21 is fixedly connected to the side wall of the box body 1, so that the gas after reacting with the sprayed waste gas treatment liquid can pass through the filtrate net 21 to remove the mist mixed in the above-mentioned gas, and the filtered mist can fall directly into the liquid storage tank 5 located in the first chamber 01 along the direction of gravity after continuous condensation, so as to reduce the risk of leakage of the equipment, thereby reducing the risk of environmental pollution.

[0031] In addition, if Figure 2 As shown, the exhaust gas treatment device can also be arranged in a horizontal direction. In the present invention, the exhaust gas treatment device adopting this placement method can be called a horizontal exhaust gas treatment device. In this embodiment, the exhaust gas treatment unit 2 can include two filter screens 24, along the direction from the first chamber 01 to the second chamber 02 (such as Figure 2 The two filters 24 are spaced apart, and the edge of each filter 24 abuts the side wall of the housing 1. Exhaust gas adsorption material is contained between the two filters 24. As the exhaust gas passes through the exhaust gas adsorption material via the first chamber 01, the exhaust gas adsorption material adsorbs dust and other particles in the exhaust gas, thereby purifying the exhaust gas. Alternatively, the exhaust gas adsorption material may be, for example, activated carbon or carbon fiber, to purify the exhaust gas while reducing production costs.

[0032] In addition, a feed port and a discharge port are provided on the side wall of the box body 1. The feed port and the discharge port are opposite to and connected to the space containing the exhaust gas adsorbent material (hereinafter referred to as the filling bin). In this way, new exhaust gas adsorbent material can be added to the filling bin through the feed port, and used exhaust gas adsorbent material in the filling bin can be removed through the discharge port. When setting the discharge port, the discharge port can be placed closer to the ground relative to the feed port to improve the efficiency of removing the exhaust gas adsorbent material.

[0033] With the exhaust gas treatment equipment provided by the present invention, since the induced draft fan 3 is directly disposed within the second chamber 02, it can avoid the induced draft fan 3 from occupying additional space outside the housing 1. This can effectively reduce the floor space of the exhaust gas treatment equipment while improving the integration of the exhaust gas treatment equipment. Furthermore, since the air outlet of the induced draft fan 3 located in the second chamber 02 faces the air outlet 12 of the housing 1, during the exhaust gas treatment process, the air pressure in the first chamber 01 can be greater than the air pressure in the second chamber 02, which is beneficial for improving gas flow efficiency and thus effectively improving exhaust gas purification.

[0034] It is worth mentioning that, in a specific embodiment, continue to refer to Figure 2 Since the air inlet of the induced draft fan 3 faces the exhaust gas treatment unit 2, during the exhaust gas treatment process, the clean gas purified by the exhaust gas treatment unit 2 can directly enter the induced draft fan 3 through the air inlet of the induced draft fan 3. In addition, since the air outlet 12 of the housing 1 is located on the side of the induced draft fan 3 away from the exhaust gas treatment unit 2, and the air outlet of the induced draft fan 3 faces the air outlet 12, the clean gas blown out from the air outlet of the induced draft fan 3 can be directly discharged to the outside of the housing 1 through the air outlet 12 of the housing 1, thereby effectively shortening the flow path of the clean gas, thereby facilitating the improvement of the purification efficiency of the exhaust gas treatment equipment.

[0035] In addition, the diameter D of the air outlet 12 of the box body 1 satisfies φ200mm≤D≤φ1000mm. In practical applications, the diameter D of the air outlet 12 can be adjusted according to actual needs. An exemplary diameter D can be φ300mm or φ800mm.

[0036] In a possible embodiment of the present invention, the diameter of the air outlet of the induced draft fan 3 is larger than the diameter of the air outlet 12, that is, along the direction from the exhaust gas treatment unit 2 to the air outlet 12, the projection of the air outlet of the induced draft fan 3 on the box body 1 can completely cover the air outlet 12 of the box body 1, so as to effectively reduce the reflux of the external gas of the box body 1 back to the inside of the box body 1, while making the clean gas blown out of the air outlet of the induced draft fan 3 directly cover the entire air outlet 12 and be blown out through the air outlet 12, which is conducive to improving the flow efficiency of the clean gas flowing to the outside of the box body 1 and further improving the purification efficiency of the equipment.

[0037] In a specific embodiment, Figure 1 As shown, the exhaust gas treatment equipment can also be provided with a mounting bracket 4, which is located in the second chamber 02 and between the exhaust fan 3 and the exhaust gas treatment unit 2. By fixing the mounting bracket 4 to the side wall of the housing 1 and placing the exhaust fan 3 on the mounting bracket 4, the connection reliability between the exhaust fan 3 and the housing 1 is improved. It is worth mentioning that the setting direction of the exhaust gas treatment equipment can be adjusted according to the use requirements to meet the needs of different application scenarios.

[0038] In addition, continue to refer to Figure 1 The mounting frame 4 may include, but is not limited to, a support 41 and a vibration-damping structure 42. The vibration-damping structure 42 is located between the support 41 and the induced draft fan 3, with one side of the vibration-damping structure 42 connected to the support 41 and the other side connected to the induced draft fan 3. This prevents a rigid connection between the induced draft fan 3 and the housing 1, thereby reducing the risk of damage to the induced draft fan 3 due to vibration during transportation or operation of the exhaust gas treatment equipment.

[0039] When setting the supports, refer to Figure 3 , Figure 3 for Figure 1 The schematic diagram of the partial structure of the exhaust gas treatment equipment provided by the invention is used to show the structure of the support 41 along the Z-axis direction. Specifically, the support 41 includes a fixed portion 411 and a hollow portion 412, wherein the fixed portion 411 can be an annular structure, and the area surrounded by the inner circle of the annular structure is the hollow portion 412. In addition, as Figure 1 As shown, when the exhaust gas treatment device is arranged in the vertical direction, the fixing portion 411 ( Figure 1The side wall of the fixed portion 411 (not shown) is fixedly connected to the side wall of the housing 1. The vibration reduction structure 42 is provided on the side of the fixed portion 411 relative to the exhaust gas treatment unit 2 close to the air outlet 12. The hollow portion 412 is used to provide a flow channel for the clean gas, so that the clean gas can flow directly to the air outlet 12 of the housing 1.

[0040] In the present invention, the distribution ratio of the fixed portion 411 and the hollow portion 412 of the support 41 can be exemplarily 1:2 or 2:3, and at least a portion of the hollow portion 412 is arranged opposite the air inlet of the fan. This improves the flow efficiency of the gas inside the box 1 and the cleaning efficiency of the equipment while meeting the strength requirements of the support 41. It is understood that the distribution of the fixed portion 411 can be adjusted based on factors such as the strength of the fixed portion 411 itself and the weight of the induced draft fan 3.

[0041] When specifically providing the vibration-damping structure 42, the vibration-damping structure 42 can be exemplarily a spring damper, one end of which is connected to the induced draft fan 3 and supports the induced draft fan 3, and the other end of which is connected to the fixing portion 411 of the support 41. In addition, multiple spring dampers can be provided, and the multiple spring dampers are evenly distributed on the fixing portion 411 to support the induced draft fan 3, which is conducive to improving the buffering and vibration reduction effect of the induced draft fan 3 and further improving the connection reliability between the induced draft fan 3 and the housing 1.

[0042] When specifically setting up the induced draft fan 3, one or more induced draft fans 3 can be set up, and multiple induced draft fans 3 are fixedly connected to the mounting frame 4, and the sum of the projected areas of the air inlets of multiple induced draft fans 3 on the exhaust gas treatment unit 2 is greater than the projected area of ​​the air inlet of one induced draft fan 3 on the exhaust gas treatment unit 2. In this way, the clean gas purified by the exhaust gas treatment unit 2 can be directly sucked into the air inlet of the corresponding induced draft fan 3, and blown out toward the air outlet 12 through the air outlet of the induced draft fan 3, thereby effectively improving the flow efficiency of the airflow and improving the purification efficiency of the equipment. It is understandable that one mounting frame 4 can be installed with multiple induced draft fans 3, and each induced draft fan 3 is correspondingly connected to one or more spring shock absorbers. Or in other possible embodiments, multiple induced draft fans 3 are installed on multiple mounting frames 4 in a one-to-one correspondence.

[0043] It should be noted that multiple induced draft fans 3 can be connected in series or in parallel according to the actual application scenario. Specifically, when one induced draft fan 3 cannot meet the required air volume, two or more induced draft fans 3 can be installed in one system and run in parallel to transport the gas together. Exemplarily, induced draft fans 3 of the same model can be used. In addition, when one induced draft fan 3 cannot overcome the wind resistance of the external environment, two or more induced draft fans 3 can be installed in one system and run in series, and the air supply volume of each induced draft fan 3 running in series is equal.

[0044] In addition, the type of the above-mentioned induced draft fan 3 can be selected according to actual needs, and can be, for example, a common type, an anti-corrosion type, an explosion-proof type, or an anti-corrosion and explosion-proof type.

[0045] In a specific embodiment, Figure 2 As shown, when the exhaust gas treatment device is arranged horizontally, the mounting frame 4 is located between the fan and the side wall of the housing 1, and the side of the support 41 facing away from the induced draft fan 3 is fixedly connected to the side wall of the housing 1. This ensures that the mounting frame 4 supports the induced draft fan 3 in the direction of gravity, and because the exhaust gas treatment device occupies a small area, it can be applied in a wide range of scenarios.

[0046] In addition, in the exhaust gas treatment setting provided by the present invention, the distance between the air outlet of the induced draft fan 3 and the air outlet 12 is L, and L satisfies: 0mm≤L≤1000mm. For example, L can be 100mm or 200mm. This can effectively reduce the volume of the box 1 while ensuring the air flow efficiency, and effectively reduce the footprint of the equipment.

[0047] It can be understood that when L=0 mm, the air outlet of the induced draft fan 3 coincides with the air outlet 12 , which can further reduce the volume of the box body 1 and further reduce the floor space occupied by the exhaust gas treatment equipment.

[0048] In summary, in the exhaust gas treatment equipment provided by the present invention, since the induced draft fan 3 is directly disposed in the second chamber 02, it can avoid the induced draft fan 3 from occupying additional space outside the housing 1, and while improving the integration of the exhaust gas treatment equipment, it can also effectively reduce the floor space of the exhaust gas treatment equipment. In addition, since the air outlet of the induced draft fan 3 located in the second chamber 02 is oriented toward the air outlet 12 of the housing 1, during the exhaust gas treatment process, the air pressure in the first chamber 01 can be made greater than the air pressure in the second chamber 02, which is conducive to improving the gas flow efficiency, thereby effectively improving the exhaust gas purification.

[0049] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
