Description

Technical Field

[0001] This utility model relates to the field of industrial gas treatment technology, specifically to an efficient dust removal and humidification device for industrial gases. Background Technology

[0002] During industrial production, a large amount of industrial gases containing dust, particulate matter, and harmful impurities are generated. If these gases are directly emitted, they will not only cause serious environmental pollution but may also harm human health. Therefore, dust removal and purification of industrial gases is an indispensable part of industrial production. At the same time, some industrial scenarios (such as chemical, metallurgical, and building materials industries) have specific requirements for the humidity of the treated gases. Dry gases may cause secondary dust, equipment wear, or affect subsequent processes, so humidification is required after dust removal.

[0003] Currently, existing industrial gas treatment devices have certain limitations in dust removal efficiency and humidification effect. For example, some dust removal devices have limited contact area between the filter material and the gas, resulting in insufficient dust interception and low dust removal efficiency. Moreover, filter material replacement and maintenance are complicated, increasing labor costs and downtime. In addition, some dust removal devices have insufficient deep purification capabilities and are difficult to effectively adsorb fine impurities and odors in the gas.

[0004] According to the patent application published on the Internet, an industrial gas high-efficiency dust removal and humidification device (authorization announcement number: CN215939464U) is described as including "box body, fixed plate" etc., to achieve dust removal and humidification.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This industrial gas high-efficiency dust removal and humidification device uses a housing and fixed plate to achieve dust removal and humidification. During use, the device removes dust through activated carbon adsorption cotton and filter screens. However, these two sets of filtration equipment cannot be disassembled, which affects the filtration effect over a long period of use. Furthermore, the direct spraying of water for humidification during filtration further impairs the adsorption effect of the activated carbon adsorption cotton due to the humid gas, increasing the rate of clogging. Therefore, this device needs to be improved. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: an industrial gas high-efficiency dust removal and humidification device, comprising a processing box, a sealing cover slidably connected to the top of the processing box, an air inlet pipe fixedly connected to the top of the sealing cover, a fixed shaft threadedly connected inside the sealing cover, a dust removal mechanism inside the processing box, a humidification mechanism on the right side of the processing box, and a load-bearing frame fixedly connected to the inner side of the processing box.

[0009] The dust removal mechanism includes a support frame, which is disposed on the top of a load-bearing frame. A fixed frame is fixedly connected to the inner side of the support frame. A filter basket is slidably connected inside the fixed frame. A filter bag is slidably connected inside the filter basket. An activated carbon frame is slidably connected inside the fixed frame. A first limiting shaft is threadedly connected inside the activated carbon frame. A limiting plate is disposed on the top of the fixed frame. A fixing ring is fixedly connected to the bottom of the limiting plate. The fixing ring is disposed on the top of the filter bag. A second limiting shaft is threadedly connected inside the limiting plate.

[0010] Preferably, the fixing shaft extends through the top of the processing box, the first limiting shaft extends through the inside of the fixing frame, and the second limiting shaft extends through the top of the fixing frame. This allows the fixing shaft to ensure the stability of the sealing cover, and the first limiting shaft to ensure the stability of the activated carbon frame.

[0011] Preferably, the bottom of the support frame is in contact with the top of the load-bearing frame, and both the support frame and the fixed frame are slidably connected inside the processing box, so that the stability of the support frame and the fixed frame can be ensured by the load-bearing frame.

[0012] Preferably, the activated carbon frame is located at the bottom of the filter basket, and a feeding port is provided at the top of the activated carbon frame. The feeding port is circular. The bottom of the limiting plate is in contact with the top of the treatment box, and the bottom of the fixing ring is in contact with the top of the filter bag. This allows the filter basket and filter bag to be fixed by the fixing ring without affecting the air intake effect.

[0013] Preferably, the filter basket and filter bag are provided in four sets and symmetrically distributed inside the fixed frame, which facilitates the improvement of filtration efficiency.

[0014] Preferably, the humidification mechanism includes a fixed platform, which is fixedly connected to the right side of the treatment box. A humidification box is fixedly connected to the right side of the fixed platform. A fan is fixedly connected to the top of the fixed platform. A water tank is fixedly connected to the left side of the top of the fixed platform. A delivery pipe is fixedly connected to the right side of the water tank. A water storage device is fixedly connected to the bottom of the right end of the delivery pipe. A nozzle is fixedly connected to the bottom of the water storage device. A water pump is fixedly connected to the periphery of the delivery pipe. The water pump is fixedly connected to the top of the fixed platform.

[0015] Preferably, the right side of the fan is fixedly connected to the left side of the humidification box, and the water tank is fixedly connected to the top of the humidification box, so that the dust-removed gas can be transported into the humidification box by the fan.

[0016] Compared with the prior art, this utility model provides an industrial gas high-efficiency dust removal and humidification device, which has the following beneficial effects:

[0017] 1. This high-efficiency dust removal and humidification device for industrial gases, through its dust removal mechanism, features four sets of filter baskets and filter bags symmetrically distributed within a fixed frame when industrial gases require dust removal. This multi-set layout significantly increases the contact area between the gas and the filter material, enabling more effective interception of dust particles in the industrial gas and improving dust removal efficiency. Simultaneously, the activated carbon frame at the bottom of the filter basket can be easily replenished with activated carbon through a circular feeding port at the top. Utilizing the strong adsorption properties of activated carbon, it deeply purifies the gas that has undergone preliminary filtration by the filter bags, effectively adsorbing fine impurities and odors, thus significantly improving the cleanliness of the treated gas. The filter basket, filter bags, and fixed frame are slidably connected, and the activated carbon frame is also slidably connected within the fixed frame. Combined with the threaded connection of the first and second limiting shafts, the disassembly and installation of each filter component are extremely simple. When the filter bag needs replacement due to excessive dust adsorption, or when the activated carbon becomes saturated and needs replacement, simply unscrew the corresponding limiting shaft to easily remove the filter basket, filter bag, or activated carbon frame. No complex tools are required, significantly shortening maintenance time and reducing labor costs.

[0018] 2. This industrial gas high-efficiency dust removal and humidification device, through its humidification mechanism, allows the fan to smoothly introduce the dust-treated gas into the humidification box. The water storage tank is connected to the water tank through a delivery pipe, which can continuously supply water to the nozzles. The nozzles can evenly spray or atomize the water, allowing the gas and water vapor to fully contact each other, achieving high-efficiency humidification. The integrated design of dust removal and humidification allows industrial gases to complete two key treatment processes in the same device, eliminating the need for additional separate equipment, saving space and costs, while ensuring the continuity and efficiency of the treatment process.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-7This utility model provides a technical solution: an industrial gas high-efficiency dust removal and humidification device, including a treatment box 1, a sealing cover 2 slidably connected to the top of the treatment box 1, an air inlet pipe 3 fixedly connected to the top of the sealing cover 2, a fixed shaft 4 threadedly connected inside the sealing cover 2, a dust removal mechanism 5 inside the treatment box 1, a humidification mechanism 6 on the right side of the treatment box 1, and a load-bearing frame 7 fixedly connected to the inner side of the treatment box 1.

[0033] The dust removal mechanism 5 includes a support frame 51, which is located on top of the load-bearing frame 7. A fixed frame 52 is fixedly connected to the inner side of the support frame 51. A filter basket 56 is slidably connected inside the fixed frame 52. A filter bag 57 is slidably connected inside the filter basket 56. An activated carbon frame 53 is slidably connected inside the fixed frame 52. A first limiting shaft 55 is threadedly connected inside the activated carbon frame 53. A limiting plate 54 is provided at the top of the fixed frame 52. A fixing ring 58 is fixedly connected to the bottom of the limiting plate 54. The fixing ring 58 is located at the top of the filter bag 57. A second limiting shaft 59 is threadedly connected inside the limiting plate 54.

[0034] The fixed shaft 4 passes through the top of the processing box 1, the first limiting shaft 55 passes through the inside of the fixed frame 52, and the second limiting shaft 59 passes through the top of the fixed frame 52. This allows the fixed shaft 4 to ensure the stability of the sealing cover 2, and the first limiting shaft 55 to ensure the stability of the activated carbon frame 53.

[0035] The bottom of the support frame 51 is in contact with the top of the load-bearing frame 7. Both the support frame 51 and the fixed frame 52 are slidably connected inside the processing box 1, so that the load-bearing frame 7 can ensure the stability of the support frame 51 and the fixed frame 52.

[0036] The activated carbon frame 53 is located at the bottom of the filter basket 56, and the top of the activated carbon frame 53 has a feeding port, which is circular. The bottom of the limiting plate 54 is in contact with the top of the treatment box 1, and the bottom of the fixing ring 58 is in contact with the top of the filter bag 57. This allows the filter basket 56 and the filter bag 57 to be fixed by the fixing ring 58 without affecting the air intake effect.

[0037] There are four sets of filter baskets 56 and filter bags 57, which are symmetrically distributed inside the fixed frame 52 to improve filtration efficiency.

[0038] Example 2

[0039] Please see Figure 1-7Furthermore, based on Embodiment 1, the humidification mechanism 6 further includes a fixed platform 61, which is fixedly connected to the right side of the processing box 1. A humidification box 62 is fixedly connected to the right side of the fixed platform 61. A fan 64 is fixedly connected to the top of the fixed platform 61. A water tank 65 is fixedly connected to the left side of the top of the fixed platform 61. A conveying pipe 67 is fixedly connected to the right side of the water tank 65. A water storage device 63 is fixedly connected to the bottom of the right end of the conveying pipe 67. A nozzle 68 is fixedly connected to the bottom of the water storage device 63. A water pump 66 is fixedly connected to the periphery of the conveying pipe 67. The water pump 66 is fixedly connected to the top of the fixed platform 61.

[0040] The fan 64 is fixedly connected to the left side of the humidification box 62 on the right side, and the water tank 63 is fixedly connected to the top of the humidification box 62, so that the dust-removed gas can be transported into the humidification box 62 by the fan 64.

[0041] In actual operation, when this device is used to remove dust from industrial gases, firstly, the filter basket 56 is slidably connected to the inside of the fixed frame 52, and the filter bag 57 is slidably connected to the inside of the filter basket 56. When the installation is completed, the bottom of the limiting plate 54 can be in contact with the top of the fixed frame 52, and the bottom of the fixing ring 58 can be in contact with the top of the filter bag 57. At the same time, the limiting plate 54 is fixed by the second limiting shaft 59, which can make the filter basket 56 and the filter bag 57 stable inside the fixed frame 52 without affecting the air intake effect. Activated carbon is added into the activated carbon frame 53 through the feeding port at the top of the activated carbon frame 53, and the activated carbon frame 53 is slidably connected to the inside of the fixed frame 52. The activated carbon frame 53 is fixed by the first limiting shaft 55.

[0042] At this point, the fixed frame 52 can drive the support frame 51 to slide and connect inside the fixed frame 52, so that the bottom of the support frame 51 and the top of the load-bearing frame 7 come into contact with each other. At the same time, the sealing cover 2 is slidably connected to the top of the processing box 1. The sealing cover 2 and the processing box 1 are fixed together by the fixed shaft 4. The external gas pipeline is connected to the air inlet pipe 3, so that the gas that needs to be dusted and humidified can be transported into the processing box 1.

[0043] When the gas enters the treatment chamber 1 and passes through the fixed frame 52 into the filter bag 57 and filter basket 56, the filter basket 56 and filter bag 57 are set in four groups and symmetrically distributed inside the fixed frame 52. This multi-group layout greatly increases the contact area between the gas and the filter material, which can more fully intercept dust particles in the industrial gas and improve dust removal efficiency. The gas after dust removal will move downwards. The activated carbon frame 53 located at the bottom of the filter basket 56 uses the strong adsorption of activated carbon to deeply purify the gas that has been initially filtered by the filter bag 57, effectively adsorbing fine impurities and odors, and greatly improving the cleanliness of the treated gas.

[0044] When the fan 64 is started, it smoothly introduces the dust-treated gas into the humidification box 62. The water pump 66 transports the water in the water tank 65 to the water storage tank 63 through the delivery pipe 67, which continuously supplies water to the nozzle 68. The nozzle 68 can spray or atomize the water evenly, so that the gas and water vapor can fully contact each other and achieve efficient humidification. The integrated design of dust removal and humidification allows industrial gas to complete two key treatment processes in the same device without the need for additional separate equipment, saving space and cost, while ensuring the continuity and efficiency of the treatment process. The gas after dust removal and humidification will be discharged through the right side of the humidification box 62.

[0045] The filter basket 56, filter bag 57, and fixed frame 52 are slidably connected. The activated carbon frame 53 is also slidably connected to the fixed frame 52. With the threaded connection of the first limiting shaft 55 and the second limiting shaft 59, the disassembly and installation of each filter component is extremely simple. When the filter bag 57 needs to be replaced due to excessive dust adsorption, or when the activated carbon needs to be replaced due to saturation, simply unscrew the corresponding limiting shaft to easily pull out the filter basket 56, filter bag 57, or activated carbon frame 53. No complicated tools are required, which greatly shortens maintenance time and reduces labor costs. When it is necessary to clean the filter basket 56 and filter bag 57, or add activated carbon to the activated carbon frame 53, simply reverse the above steps.

[0046] The fixed frame 52 in this case has a through-type internal design, which facilitates the flow of gas. Moreover, the design of this case can perform dust removal and humidification work on industrial gases generated in the fields of chemical industry, metallurgy, and building materials.
