Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically to an absorption device for acid mist in electrolytic cells. Background Technology

[0002] An electrolytic cell is a device used for electrolytic reactions. When electrolyzing a cathode plate, the cathode plate is usually immersed in an electrolytic cell containing high-temperature liquid. The high-temperature immersion is used to remove residual sulfuric acid adhering to the surface of the cathode plate.

[0003] However, in some processing environments, especially in winter, the temperature difference between the high-temperature liquid inside the electrolytic cell and the external environment can easily lead to the generation of water vapor in the workshop. This water vapor is an acidic gas, which can damage the workshop environment and the health of the workers inside. Therefore, workers need to wear masks in the workshop to reduce the harm of acidic gases to their bodies.

[0004] Although wearing masks can reduce the harm of acidic gases to the body, it is difficult to avoid a small amount of acidic gases still affecting the staff. Moreover, with the increase in working hours, there will still be serious environmental pollution and health hazards to the staff. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an absorption device for acid mist in electrolytic cells, so as to solve the technical problem in the background art that acidic gases can cause serious environmental pollution and harm the health of workers.

[0006] The present invention provides an absorption device for acid mist in an electrolytic cell, comprising multiple absorption boxes for burying underground, multiple suction hoods for placing on the ground, a fan, and a transmission pipe.

[0007] The multiple absorption boxes have different sizes and are interconnected. One absorption box is connected to the transmission pipe, and another absorption box is connected to the output end of the fan. The output end of the fan is used to connect to the recycling system.

[0008] The plurality of suction hoods are arranged along the length of the transmission pipe, and each suction hood is connected to the transmission pipe so that the fan outputs suction medium, thereby allowing external airflow to enter the absorption box through each suction hood and the transmission pipe.

[0009] Furthermore, the absorption device also includes multiple valves;

[0010] The transmission tube includes a main body and a plurality of sub-tubes that are interconnected with the main body. The main body is connected to an absorption box, and the plurality of sub-tubes are respectively connected to a plurality of air intake hoods.

[0011] Each of the valves is located on each of the sub-pipe bodies.

[0012] Furthermore, each of the aforementioned air intake hoods is connected to a plurality of the aforementioned sub-tubes.

[0013] Furthermore, multiple sub-tubes are spaced apart along the length of the air intake hood.

[0014] Furthermore, multiple air intake hoods are symmetrically arranged on opposite sides of the main body.

[0015] Furthermore, the size of the communication area between the main body and the absorption box is larger than the size of the two end areas of the main body, so as to form a buffer area on the main body.

[0016] Furthermore, the absorption device includes a first absorption chamber, a second absorption chamber, and a third absorption chamber that are interconnected.

[0017] Furthermore, the second absorption chamber is disposed between the first absorption chamber and the third absorption chamber.

[0018] Furthermore, the size of the first absorption box is larger than the size of the second absorption box, and the size of the third absorption box is larger than the size of the first absorption box.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the absorption device for acid mist in electrolytic cells provided by this utility model, the arrangement of multiple absorption chambers, multiple suction hoods, fans, and transmission pipes allows for the treatment of acidic gases. The fans generate suction, which is then transmitted through the multiple absorption chambers and transmission pipes. Each suction hood generates suction, drawing acidic gases from multiple locations within the workshop through the corresponding suction hood into the transmission pipe and then into the absorption chamber. The varying sizes of the multiple absorption chambers ensure sufficient residence time for the acidic gases within each chamber. Finally, the fans output the acidic gases to the recovery and treatment system, thus completing the treatment of the acidic gases and solving the technical problems of severe environmental pollution and harm to worker health caused by acidic gases in existing technologies.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figure 1 The image shows an absorption device for acid mist from an electrolytic cell according to one embodiment of the present invention. It includes multiple absorption boxes for burying underground, multiple suction hoods 1 for placing on the ground, a fan 9, and a transmission pipe. It should be noted that in this embodiment, the absorption device is specifically installed in a workshop with an electrolytic cell. When the electrolytic cell is running, the temperature difference between the high-temperature liquid inside the electrolytic cell and the external environment can easily cause water vapor to be generated in the workshop. Moreover, the generated water vapor is an acidic gas, which can damage the workshop environment and the health of the workers in the workshop.

[0027] In this embodiment, the multiple absorption boxes are of different sizes and are interconnected. One absorption box is connected to the transmission pipe, and another absorption box is connected to the output end of the fan 9. The output end of the fan 9 is used to connect to the recycling system.

[0028] Multiple suction hoods 1 are arranged along the length of the transmission pipe, and each suction hood 1 is connected to the transmission pipe so that the fan 9 outputs the suction medium, so that the external airflow enters the absorption box through each suction hood 1 and the transmission pipe respectively.

[0029] To avoid environmental pollution caused by acidic gases in the workshop and to reduce the harm to workers' health caused by acidic gases, in this embodiment, a fan 9 is used to generate suction. Through multiple absorption chambers and transmission pipes, each suction hood 1 can generate suction, thereby drawing acidic gases from multiple locations in the workshop into the transmission pipes via the corresponding suction hood 1 and into the absorption chambers. By using multiple absorption chambers of different sizes, the residence time of acidic gases in multiple absorption chambers can be guaranteed. Finally, the fan 9 outputs the acidic gases to the recycling and treatment system, thereby completing the treatment of acidic gases and solving the technical problems of acidic gases causing serious environmental pollution and harming workers' health in the prior art.

[0030] It should be noted that the recovery and treatment system is a system used to treat acidic gases, which is conventional prior art in this field, and therefore will not be described in detail here.

[0031] To further understand this case, in this example, there can be three absorption boxes, specifically the first absorption box 6, the second absorption box 7, and the third absorption box 8 that are interconnected. It should be noted that the number of absorption boxes is not limited to three; other numbers of absorption boxes may also be included. No particular limitation is made here. Furthermore, the absorption boxes are existing technology and can be waste gas absorption boxes.

[0032] Specifically, the second absorption box 7 is located between the first absorption box 6 and the third absorption box 8, and the size of the first absorption box 6 is larger than the size of the second absorption box 7, and the size of the third absorption box 8 is larger than the size of the first absorption box 6. In some preferred embodiments, the size of the first absorption box 6 can be 1500*1500*2000, the size of the second absorption box 7 can be 1500*1500*1000, and the size of the third absorption box 8 can be 1500*1500*3000.

[0033] In addition, to further improve the practicality of the absorption device in this embodiment, the absorption device also includes multiple valves 3, and the transmission pipe includes a main body 2 and multiple sub-pipes 4 that are interconnected with the main body 2. The main body 2 is connected to an absorption box, and the multiple sub-pipes 4 are respectively connected to multiple suction hoods 1. Each valve 3 is respectively provided on each sub-pipe 4.

[0034] Specifically, each suction hood 1 is connected to multiple sub-pipes 4, and the multiple sub-pipes 4 are spaced apart along the length of the suction hood 1. Through the arrangement of multiple sub-pipes 4 and valves 3, the suction volume of each suction hood 1 can be controlled. In some practical cases, a PLC controller can be arranged to control each valve 3, so that the fan 9 can output the corresponding power according to the concentration of acidic gas in the workshop, and then control each valve 3 separately, so as to ensure the economy of the absorption device during use while absorbing acidic gas.

[0035] In addition, multiple suction hoods 1 are symmetrically arranged on opposite sides of the main body 2, and the size of the communication area between the main body 2 and an absorption box is larger than the size of the two ends of the main body 2, so as to form a buffer area 5 on the main body 2.

[0036] In summary, the absorption device for acid mist in an electrolytic cell according to one embodiment of this invention has at least the following advantages compared with existing methods for treating acidic gases:

[0037] In the absorption device for acid mist in electrolytic cells provided by this utility model, the arrangement of multiple absorption chambers, multiple suction hoods 1, fans 9, and transmission pipes enables the treatment of acidic gases. The fans 9 generate suction, which is then transmitted through the multiple absorption chambers and transmission pipes. Each suction hood 1 generates suction, drawing acidic gases from multiple locations within the workshop through the corresponding suction hood 1 into the transmission pipe and then into the absorption chamber. The different sizes of the multiple absorption chambers ensure sufficient residence time for the acidic gases within them. Finally, the fans 9 output the acidic gases to the recovery and treatment system, thus completing the treatment of the acidic gases and solving the technical problems of severe environmental pollution and harm to worker health caused by acidic gases in existing technologies.
