Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment device for processing acidic gases. Background Technology

[0002] In industrial production sectors such as chemical, metallurgical, power, and metal processing industries, the emission of waste gases containing acidic gases, such as sulfur dioxide, hydrogen chloride, and nitrogen oxides, is a common environmental governance challenge. If these acidic gases are directly released into the atmosphere, they will not only exacerbate regional environmental problems such as acid rain and smog, and cause continuous damage to soil, water bodies, and vegetation, but also cause irreversible health damage to the respiratory system, skin, and mucous membranes of people in the surrounding areas. Therefore, efficient purification and treatment of acidic gases has become an indispensable key link in industrial production.

[0003] Most devices rely on a single purification process, making it difficult to simultaneously and efficiently treat dust, particulate matter, and acidic gases in the exhaust gas. If spraying is performed first, dust in the exhaust gas can easily clog the spray nozzles, resulting in uneven distribution of the chemical solution and incomplete neutralization of acidic gases. If only filtration is performed, gaseous acidic components cannot be removed, and the purification effect is far from meeting environmental emission standards.

[0004] According to the description of a waste gas treatment device published on the patent website (authorization announcement number: CN219308213U), the waste gas treatment device includes "fan, waste gas treatment device" etc., to achieve the treatment work.

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

[0006] This waste gas treatment device uses a fan and other components to perform the treatment. However, it only filters the waste gas through a filter screen, which cannot filter out the gaseous pollutants, dissolved pollutants, and reactive pollutants that make up a large proportion of the waste gas. This results in incomplete purification and affects the treatment effect. Therefore, this device needs to be improved. Utility Model Content

[0007] The purpose of this invention is to provide a waste gas treatment device for processing acidic gases, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device for processing acidic gases, comprising a base, a treatment mechanism on the top of the base, a sealing mechanism on the top of the treatment mechanism, and a support platform fixedly connected to the right side of the top of the base;

[0009] The processing mechanism includes a sealed box, which is fixedly connected to the top left side of the base. An air inlet pipe is fixedly connected to the top left side of the sealed box. An installation base is fixedly connected to the inside of the sealed box. A filter basket is fixedly connected inside the installation base. A filter bag is slidably connected inside the filter basket. A fan is fixedly connected to the bottom right side of the sealed box. A connecting pipe is fixedly connected to the top of the fan. A spray tower is fixedly connected to the right side of the connecting pipe. A spray head is fixedly connected to the top of the spray tower. A diversion pipe is fixedly connected to the outside of the spray head. A delivery pipe is fixedly connected to the bottom of the diversion pipe. A liquid storage tank is fixedly connected to the left side of the bottom end of the delivery pipe. A water pump is fixedly connected to the outside of the delivery pipe. A connector is fixedly connected to the rear side of the liquid storage tank.

[0010] Preferably, the top of the outer periphery of the filter bag is in contact with the top of the mounting base and the filter basket, and the fan is fixedly connected to the top of the base, which facilitates the preliminary filtration of exhaust gas through the filter bag.

[0011] Preferably, the spray tower is fixedly connected to the inside of the support platform, and a waste discharge pipe is fixedly connected to the bottom of the spray tower to facilitate the stability of the spray tower through the support platform.

[0012] Preferably, the inner side of the nozzle is inclined to the bottom, and there are four sets of nozzles symmetrically distributed inside the diversion pipe, which facilitates the spraying of treatment liquid through the nozzles to further treat the exhaust gas.

[0013] Preferably, the water pump and the storage tank are fixedly connected to the top of the base to facilitate the transportation of the treatment liquid by the water pump.

[0014] Preferably, the sealing mechanism includes a sealing cover, which is threaded to the top of the outer periphery of the sealing box. A connecting rod is fixedly connected to the top of the inner side of the sealing cover, and a limiting plate is fixedly connected to the bottom of the connecting rod. The limiting plate is located on the top of the filter bag.

[0015] Preferably, the connecting rod and the limiting plate are slidably connected to the inside of the sealing box, and the bottom of the limiting plate is in contact with the top of the filter bag, which facilitates sealing the top of the sealing box through the sealing cover and ensures the stability of the filter bag.

[0016] Compared with the prior art, this utility model provides a waste gas treatment device for processing acidic gases, which has the following beneficial effects:

[0017] 1. This waste gas treatment device for processing acidic gases, through its set treatment mechanism, connects an external waste gas discharge pipe to an inlet pipe when waste gas needs to be treated during the processing of acidic gases. Simultaneously, based on the composition of the waste gas, an external treatment liquid delivery pipe connects to a connector to deliver the corresponding neutralizing agent or acidic absorbent to the storage tank. When the waste gas enters the sealed box, the filter bags inside the sealed box can first intercept dust, particulate matter, and other impurities in the waste gas, preventing impurities from clogging the nozzles or affecting the reaction of the liquid in the subsequent spraying stage. Subsequently, the fan transports the pre-filtered waste gas to the spray tower through the connecting pipe. Multiple sets of inclined nozzles in the spray tower form a uniform spray area through a diversion pipe, allowing the acidic gas to fully contact the neutralizing liquid delivered in the storage tank, efficiently neutralizing the acidic components in the gas. Compared with a single treatment method, this significantly improves the thoroughness of waste gas purification. The treated waste gas is discharged through the top of the spray tower.

[0018] 2. This waste gas treatment device for processing acidic gases, through a sealing mechanism, allows the sealing cover to be threaded onto the outer top of the sealing box during use, thereby driving the connecting rod and the limiting plate to slide inside the sealing box. Once the sealing cover is installed, the bottom of the limiting plate can contact the top of the filter bag, ensuring the stability of the filter bag. After opening the sealing cover, the filter bag in the filter basket can be directly removed, facilitating regular replacement or cleaning of the filter bag without disassembling complex parts.

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

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: a waste gas treatment device for processing acidic gases, including a base 1, a treatment mechanism 2 is provided on the top of the base 1, a sealing mechanism 3 is provided on the top of the treatment mechanism 2, and a load-bearing platform 4 is fixedly connected to the right side of the top of the base 1.

[0033] The processing unit 2 includes a sealed box 21, which is fixedly connected to the top left side of the base 1. An air inlet pipe 22 is fixedly connected to the top left side of the sealed box 21. An installation base 26 is fixedly connected to the inside of the sealed box 21. A filter basket 27 is fixedly connected inside the installation base 26. A filter bag 28 is slidably connected inside the filter basket 27. A fan 23 is fixedly connected to the bottom right side of the sealed box 21. A connecting pipe 24 is fixedly connected to the top of the fan 23. A spray tower 25 is fixedly connected to the right side of the connecting pipe 24. A nozzle 291 is fixedly connected to the top of the spray tower 25. A diversion pipe 292 is fixedly connected to the outside of the nozzle 291. A delivery pipe 293 is fixedly connected to the bottom of the diversion pipe 292. A liquid storage tank 295 is fixedly connected to the left side of the bottom of the delivery pipe 293. A water pump 294 is fixedly connected to the outside of the delivery pipe 293. A connector 296 is fixedly connected to the rear side of the liquid storage tank 295.

[0034] The top of the outer periphery of the filter bag 28 is in contact with the top of the mounting base 26 and the top of the filter basket 27. The fan 23 is fixedly connected to the top of the base 1, which facilitates the preliminary filtration of exhaust gas through the filter bag 28.

[0035] The spray tower 25 is fixedly connected to the inside of the support platform 4, and the bottom of the spray tower 25 is fixedly connected to the waste discharge pipe 29, which facilitates the stability of the spray tower 25 through the support platform 4.

[0036] The nozzle 291 is inclined to the bottom on the inside. There are four sets of nozzles 291, which are symmetrically distributed on the inside of the diversion pipe 292, so as to facilitate the spraying of treatment liquid through the nozzles 291 for further treatment of the exhaust gas.

[0037] The water pump 294 and the liquid storage tank 295 are fixedly connected to the top of the base 1, so as to facilitate the transportation of the treatment liquid through the water pump 294.

[0038] Example 2

[0039] Please see Figure 1-7 Furthermore, based on Embodiment 1, the sealing mechanism 3 includes a sealing cover 31, which is threaded to the top of the outer periphery of the sealing box 21. A connecting rod 32 is fixedly connected to the top of the inner side of the sealing cover 31, and a limiting plate 33 is fixedly connected to the bottom of the connecting rod 32. The limiting plate 33 is located on the top of the filter bag 28.

[0040] The connecting rod 32 and the limiting plate 33 are slidably connected to the inside of the sealing box 21, and the bottom of the limiting plate 33 is in contact with the top of the filter bag 28, so that the top of the sealing box 21 can be sealed by the sealing cover 31, while ensuring the stability of the filter bag 28.

[0041] In actual operation, when this device is used, and when the waste gas needs to be treated during the processing of acidic gases, firstly, the filter bag 28 is slidably connected to the filter basket 27 for installation, and the sealing cover 31 is threaded to the top periphery of the sealing box 21, and the connecting rod 32 and the limiting plate 33 are driven to slide in the sealing box 21. After the sealing cover 31 is installed, the bottom of the limiting plate 33 can contact the top of the filter bag 28 to ensure the stability of the filter bag 28.

[0042] The exhaust gas is connected to the inlet pipe 22 via an external exhaust pipe. At the same time, according to the composition of the exhaust gas, the corresponding neutralizing agent or acidic absorbent is delivered to the storage tank 295 via an external treatment liquid delivery pipe 293 and a connector 296. When the exhaust gas enters the sealed box 21, the filter bag 28 in the sealed box 21 can first intercept dust, particulate matter and other impurities in the exhaust gas to prevent the nozzles 291 from being blocked or the reaction of the liquid from being affected by impurities in the subsequent spraying process. Then, the fan 23 delivers the pre-filtered exhaust gas to the spray tower 25 through the connecting pipe 24.

[0043] Pump 294 transports the treatment liquid in storage tank 295 to distribution pipe 292 through delivery pipe 293, and sprays it out through nozzle 291. Multiple sets of inclined nozzles 291 in spray tower 25 form a uniform spray area, so that acidic gas can fully contact the neutralizing liquid transported in storage tank 295, and efficiently neutralize the acidic components in the gas. Compared with a single treatment method, the thoroughness of waste gas purification is greatly improved. The treated waste gas will be discharged through the top of spray tower 25.

[0044] By connecting the external wastewater collection pipe to the waste discharge pipe 29, the waste liquid generated by the spraying can be recycled and treated. The staff needs to replace or clean the filter bag 28 regularly. When the filter bag 28 needs to be cleaned or replaced, the filter bag 28 in the filter basket 27 can be taken out directly after opening the sealing cover 31, which is convenient for regular replacement or cleaning of the filter bag 28 without disassembling complicated parts.

[0045] In this application, the fan 23 and the water pump 294 need to be connected to the same PLC controller near the device to ensure coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.
