Description

Technical Field

[0001] The utility model belongs to the field of waste gas emission treatment, and particularly relates to a waste gas concentration monitoring device for waste gas emission treatment. Background Technique

[0002] Industrial waste gas refers to the general term of various pollutant-containing gases discharged into the air during fuel combustion and production processes in enterprise factory areas. These waste gases enter the human body through different respiratory tracts. Some directly cause harm, and some have an accumulation effect, which will more seriously harm human health. Therefore, when treating waste gas emissions, it is necessary to use a special waste liquid concentration monitor to detect the content of harmful parts in the discharged waste gas to ensure that the waste gas emissions meet the standards.

[0003] Chinese Utility Model Patent CN219871234U discloses a waste gas concentration monitoring and alarming device, including a main body box. A fixed box is welded to the lower surface of the main body box. A fixed groove is arranged on the inner surface of the fixed box. A fixed sleeve is welded to the inner surface of the fixed groove. A fixed block is welded to the outer surface of the wall plate. The outer surface of the fixed block is fitted into the inner surface of the fixed sleeve. A positioning card slot is arranged on the inner surface of the fixed block. A positioning card block is fitted into the inner surface of the positioning card slot. For the waste gas concentration monitoring and alarming device of the utility model, by rotating the adjusting block, the threaded rod is driven to rotate. Utilizing the threaded connection between the outer surface of the threaded rod and the inner surface of the threaded sleeve, and at the same time, utilizing the sliding connection between the outer surface of the positioning slide rod and the inner surface of the sliding sleeve, the sliding plate is driven to slide left and right, so that the outer surface of the positioning card block is fitted into the positioning card slot, thereby fixing the position of the fixed block, and thus facilitating the installation and disassembly of the main body box.

[0004] The above design can quickly and stably install and disassemble the main body box of the equipment through the cooperation of multiple components, which speeds up the overall working efficiency during equipment maintenance. However, during use, due to long-term use of the waste gas content detector, a large amount of waste gas residues will exist inside the pipeline. These residues will pollute the waste gas itself when the subsequent waste gas enters, resulting in an increase in the overall harmful substance content of the waste gas and affecting the accuracy of the detection data of the subsequent detector itself and the normal use of the components themselves.

However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments. The present utility model provides the following embodiments.

[0029] As shown by Figure 1 , Figure 2 and Figure 3 , an exhaust gas concentration monitoring device for exhaust gas emission treatment includes an outer box body 1, a gas supply pipe 2, a mating pipe 3, and a concentration detector 4. A gas supply pipe 2 is fixedly installed on one side inside the outer box body 1. A mating pipe 3 is arranged inside the outer box body 1. A concentration detector 4 is fixedly installed on the inner wall of the outer box body 1. The mating pipe 3 is fixedly connected to the concentration detector 4. A cleaning mechanism 5 is fixedly installed inside the outer box body 1. The cleaning mechanism 5 includes a protective shell 51, a suction pipe 52, a pump body 53, a connecting pipe 54, a first control valve 55, and a second control valve 56. A protective shell 51 is fixedly installed at the bottom end inside the outer box body 1. The pump body 53 is fixedly installed inside the protective shell 51. A suction pipe 52 is fixedly installed at the output end of the pump body 53. The connecting pipe 54 is fixedly installed at the output end of the pump body 53. A first control valve 55 is arranged outside the connecting pipe 54. A second control valve 56 is arranged outside the mating pipe 3. A filtering mechanism 6 is fixedly installed between the gas supply pipe 2 and the mating pipe 3. An input mechanism 7 is arranged and installed on the side of the gas supply pipe 2.

[0030] In use, through the use of the input mechanism 7, the air supply pipe 2 is connected to the waste gas input pipe. Then, the waste gas is input into the inner part of the outer box body 1 through the air supply pipe 2. Through the use of the filtering mechanism 6, the particulate impurities in the waste gas are preliminarily filtered to prevent the impurities from remaining in the pipe, affecting the cleanliness inside the pipe and causing deviation in the detection data of the subsequent concentration detector 4 itself. Then, through the use of the concentration detector 4, the preliminarily filtered waste gas is detected to check the content of harmful gases in the waste gas. When it is necessary to clean the pipes inside the equipment, through the use of the cleaning mechanism 5, the pump body 53 can be automatically started, and the prepared cleaning agent is input into the mating pipe 3 through the suction pipe 52 and the communicating pipe 54 to wash the impurities remaining on the inner wall of the mating pipe 3. Moreover, through the cooperation of the mating pipe 3 and the second control valve 56, the cleaning agent is conveyed into the filtering mechanism 6 to wash the inside of the filtering mechanism 6 as well, making the overall detection pipeline cleaner and ensuring the accuracy of the detection data of the subsequent concentration detector 4 itself.

[0031] As shown by the attached Figure 4 In this embodiment, as shown, the top end of the communicating pipe 54 is communicated with the mating pipe 3, which is convenient for the cleaning agent conveyed inside the communicating pipe 54 to enter the mating pipe 3 and wash the impurities remaining inside the mating pipe 3 during use.

[0032] As shown by the attached Figure 4 In this embodiment, as shown, the mating pipe 3 is integrally in a Z shape, which extends the path of waste gas transmission during use, can effectively reduce the probability of impurities entering the concentration detector 4, and prevent the concentration detector 4 itself from being contaminated.

[0033] As shown by the attached Figure 5 In this embodiment, as shown, the filtering mechanism 6 includes an outer shell 61, a filter element 62, a third control valve 63, a waste water discharge pipe 64, and a top cover 65. An outer shell 61 is fixedly installed between the air supply pipe 2 and the mating pipe 3. The filter element 62 is arranged inside the outer shell 61. The waste water discharge pipe 64 is fixedly installed at the bottom end of the outer shell 61. A third control valve 63 is arranged outside the waste water discharge pipe 64. A top cover 65 is arranged at the top end of the outer shell 61.

[0034] During use, by installing the air supply pipe 2 and the mating pipe 3 on both sides of the outer shell 61 respectively, and then through the use of the air supply pipe 2, the waste gas is input into the outer shell 61. Under the filtration of the filter element 62, the particulate impurities in the waste gas are screened, and then other gases are continuously conveyed through the mating pipe 3, which is convenient for the subsequent concentration detector 4 to detect. The presence of the third control valve 63 and the waste water discharge pipe 64 can quickly discharge the cleaning agent input by the pump body 53.

[0035] As shown by the attached Figure 5As shown, in this embodiment, a threaded end is fixedly installed at the top end of the outer housing 61, and a meshing groove is provided inside the top cover 65, which facilitates the quick connection and disassembly of the outer housing 61 and the top cover 65 during use and makes it more convenient to replace the filter element 62 inside the outer housing 61.

[0036] As shown by the appendix Figure 6 As shown, in this embodiment, the input mechanism 7 includes a mounting block 71, an exhaust gas delivery pipe 72, a connection end 73, and a connection groove 74. The mounting block 71 is fixedly installed on the side of the air delivery pipe 2. The exhaust gas delivery pipe 72 is arranged on the side of the mounting block 71. The connection end 73 is fixedly installed on the side of the exhaust gas delivery pipe 72. A connection groove 74 is provided inside the mounting block 71, and the connection groove 74 is threadedly connected to the connection end 73.

[0037] During use, by placing the exhaust gas delivery pipe 72 on the side of the mounting block 71 and then through the cooperation of the connection end 73 and the connection groove 74, the connection between the exhaust gas delivery pipe 72 and the mounting block 71 is completed, enabling the exhaust gas to stably enter the subsequent components through the air delivery pipe 2, facilitating the use and monitoring of the subsequent components.

[0038] As shown by the appendix Figure 6 As shown, in this embodiment, rotating blocks are symmetrically and fixedly installed on the outer wall of the exhaust gas delivery pipe 72. During use, when rotating the exhaust gas delivery pipe 72, the user's hand can use the rotating blocks as a support, facilitating the subsequent quick rotation of the exhaust gas delivery pipe 72.

[0039] As shown by the appendix Figure 1 As shown, in this embodiment, a controller is provided inside the outer box 1 on the side of the concentration detector 4, and the controller is electrically connected to the concentration detector 4. During use, through the use of the controller, the overall circuit of the device is controlled to ensure the opening and closing of multiple groups of valves and the operation of the concentration detector 4 itself.
