DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application is described clearly and completely below. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the scope of protection of the present application.

[0029] Reference Figures 1 to 6 The present application provides an unorganized waste gas absorption treatment system, comprising:

[0030] The air suction cover body 100 is arranged above the unorganized waste gas generating device 200, and the top of the air suction cover body 100 is communicated with the first waste gas pipe 101. In addition, the air suction cover body 100 can be erected above the unorganized waste gas generating device through a fixing frame, and the unorganized waste gas generating device 200 can be a reaction kettle, a distillation system, a separation device, a feeding device, etc., which is determined according to the actual situation, and the present application does not make specific limitation here.

[0031] The second waste gas pipe 300 is communicated with the end of the first waste gas pipe 101 away from the air suction cover body 100 through the first flange 400, and the other end of the second waste gas pipe 300 is communicated with the waste gas main pipe 500, and the air blower 501 is arranged on the waste gas main pipe 500. When the air blower 501 is started, the unorganized waste gas generated by the unorganized waste gas generating device 200 enters the waste gas main pipe 500 through the air suction cover body 100, the first waste gas pipe 101 and the second waste gas pipe 300, and is collected and treated in the waste gas main pipe 500, thereby reducing the dispersion of the unorganized waste gas.

[0032] The first exhaust treatment layer 600 is arranged in one end of the second exhaust pipe 300 close to the first exhaust pipe 101 and used for adsorbing harmful substances in the unorganized exhaust gas; wherein, one end of the second exhaust pipe 300 is communicated with the end of the first exhaust pipe 101 away from the air inlet cover body 100 through the first flange 400, which facilitates the installation, replacement and the like of the first exhaust treatment layer 600 arranged in the second exhaust pipe 300.

[0033] The pressure sensor 700 is arranged in the second exhaust pipe 300 and above the first exhaust treatment layer 600. According to the pressure value of the unorganized exhaust gas in the second exhaust pipe 300 detected by the pressure sensor 700, the air volume of the induced draft fan 501 is adjusted; for example, if the pressure value of the unorganized exhaust gas in the second exhaust pipe 300 detected by the pressure sensor 700 is large, the air volume of the induced draft fan 501 is increased, and if the pressure value of the unorganized exhaust gas in the second exhaust pipe 300 detected by the pressure sensor 700 is small, the air volume of the induced draft fan 501 is decreased. In the actual drug production process, a control device is arranged, and the pressure sensor 700 and the induced draft fan 501 are electrically connected with the control device, that is, the pressure sensor 700 transmits the detected pressure signal to the control device, and the air volume of the induced draft fan 501 is adjusted by the control device. In addition, the specifications and models of the pressure sensor 700 and the induced draft fan 501 can be set according to actual needs, and the present application does not make specific limitation thereto.

[0034] The application provides a non-organized waste gas absorption treatment system, wherein the induced draft fan 501 on the waste gas main pipe 500 is opened, non-organized waste gas generated by the non-organized waste gas generating device 200 enters the first waste gas pipe 101 and the second waste gas pipe 300 in sequence from the air inlet of the air inlet cover body 100 arranged above the non-organized waste gas generating device 200, and the volatile organic compounds (VOCs) and other harmful substances in the non-organized waste gas are treated by the first waste gas treatment layer 600 in the second waste gas pipe 300, so that the volatile organic compounds (VOCs) and other harmful substances in the non-organized waste gas stay in the first waste gas treatment layer 600, and the treated non-organized waste gas enters the waste gas main pipe 500 and is discharged through the waste gas main pipe 500. The waste gas main pipe 500 is arranged to facilitate the centralized treatment and discharge of the non-organized waste gas generated by each device in the pharmaceutical production workshop, thereby improving the treatment and discharge efficiency of the non-organized waste gas generated in the pharmaceutical production process. In addition, the first waste gas treatment layer 600 is arranged in one end of the second waste gas pipe 300 close to the first waste gas pipe 101, and the first waste gas pipe 101 is connected with the second waste gas pipe 300 through the first flange 400, so that the first waste gas treatment layer 600 in the second waste gas pipe 300 can be replaced and cleaned, and the pressure of the non-organized waste gas treated by the first waste gas treatment layer 600 and entering the second waste gas pipe 300 can be detected in real time through the pressure sensor 700, so that the wind power of the induced draft fan 501 can be adjusted in time according to the value of the pressure sensor 700, or the first waste gas treatment layer 600 can be replaced and cleaned, thereby improving the convenience of the non-organized waste gas treatment process and ensuring the treatment efficiency of the non-organized waste gas.

[0035] In some embodiments, with reference to Figure 1 , the first branch pipe 800 is communicated with the first waste gas pipe 101, one end of the first branch pipe 800 away from the first waste gas pipe 101 is communicated with the second branch pipe 901 through the second flange 900, one end of the second branch pipe 901 away from the first branch pipe 800 is communicated with the second waste gas pipe 300, and the second waste gas treatment layer 9011 is arranged in one end of the second waste gas pipe 300 close to the first branch pipe 800; wherein, in the process of treating the non-organized waste gas, the first branch pipe 800 and the second branch pipe 901 can simultaneously with the first waste gas pipe 101 discharge the non-organized waste gas in the air inlet cover body 100 to the waste gas main pipe 500 through the second waste gas pipe 300, thereby improving the treatment efficiency of the non-organized waste gas. In addition, the arrangement of the first branch pipe 800 and the second branch pipe 901 enables the non-organized waste gas entering the air inlet cover body 100 to enter the second waste gas pipe 300 and the waste gas main pipe 500 in sequence through the first branch pipe 800 and the second branch pipe 901 when the first waste gas treatment layer 600 in the first waste gas pipe 101 is replaced, thereby ensuring the continuity of the treatment of the non-organized waste gas generated by the non-organized waste gas generating device 200.

[0036] The first exhaust pipe 101 is provided with a first valve 1011 between one end thereof communicating with the second exhaust pipe 300 and the first branch pipe 800, the second exhaust pipe 300 is provided with a second valve 301 between one end thereof communicating with the first exhaust pipe 101 and the second branch pipe 901, and the first branch pipe 800 and the second branch pipe 901 are respectively provided with a third valve 801 and a fourth valve 9012.

[0037] In the actual treatment process of the unorganized exhaust gas, the first valve 1011, the second valve 301, the third valve 801 and the fourth valve 9012 are opened, so that the unorganized exhaust gas entering the air inlet cover body 100 sequentially enters the second exhaust pipe 300 and the exhaust gas main pipe 500 through the first exhaust pipe 101 and the first branch pipe 800 and the second branch pipe 901, that is, the unorganized exhaust gas entering the air inlet cover body 100 is discharged through two pipelines at the same time, thereby improving the treatment efficiency of the unorganized exhaust gas. In addition, when it is necessary to replace and clean the first exhaust treatment layer 600, the first valve 1011 and the second valve 301 are closed, so that the unorganized exhaust gas entering the air inlet cover body 100 sequentially enters the second exhaust pipe 300 and the exhaust gas main pipe 500 through the first branch pipe 800 and the second branch pipe 901. When it is necessary to replace and clean the second exhaust treatment layer 9011, the third valve 801 and the fourth valve 9012 are closed, so that the unorganized exhaust gas entering the air inlet cover body 100 sequentially enters the second exhaust pipe 300 and the exhaust gas main pipe 500 through the first exhaust pipe 101. Thus, the continuity of the unorganized exhaust gas treatment process of the unorganized exhaust gas generating device 200 is ensured.

[0038] In some embodiments, with reference to Figure 1 The first valve 1011 in the present application is arranged on the pipe body of the first exhaust pipe 101 close to the first branch pipe 800, and the second valve 301 is arranged on the pipe body of the second exhaust pipe 300 close to the second branch pipe 901.

[0039] In the above embodiment, the arrangement positions of the first valve 1011 and the second valve 301 ensure that when the first exhaust treatment layer 600 is replaced, the unorganized exhaust gas in the air inlet cover body 100 enters the second exhaust pipe 300 and the exhaust gas main pipe 500 through the first branch pipe 800 and the second branch pipe 901 as much as possible, and does not overflow into the pipe body of the first exhaust pipe 101 between the first branch pipe 800 and the second exhaust pipe 300 and the pipe body of the second exhaust pipe 300 between the second branch pipe 901 and the first exhaust pipe 101, so that the unorganized exhaust gas in the air inlet cover body 100 enters the second exhaust pipe 300 and the exhaust gas main pipe 500 through the first branch pipe 800 and the second branch pipe 901 as much as possible, thereby improving the treatment efficiency of the unorganized exhaust gas.

[0040] In some embodiments, with reference to Figure 1The third valve 801 in the application is arranged on the pipe body of the first branch pipe 800 close to the first exhaust pipe 101, and the fourth valve 9012 is arranged on the pipe body of the second branch pipe 901 close to the second exhaust pipe 300.

[0041] In the above embodiment, the arrangement positions of the third valve 801 and the fourth valve 9012 ensure that when the second exhaust treatment layer 8011 is replaced, the unorganized exhaust gas in the air suction cover body 100 can enter the second exhaust pipe 300 and the exhaust main pipe 500 in sequence through the first exhaust pipe 101 as much as possible, and will not overflow into the first branch pipe 800 and the second branch pipe 901, so that the unorganized exhaust gas in the air suction cover body 100 can enter the second exhaust pipe 300 and the exhaust main pipe 500 in sequence through the first exhaust pipe 101 as much as possible, and the treatment efficiency of the unorganized exhaust gas is improved.

[0042] In some embodiments, referring to Figure 3 、 Figure 4 and Figure 5 , the first exhaust treatment layer 600 in the application includes a hollow porous mesh plate 601 and an activated carbon layer 602; specifically, the porous mesh plate 601 is arranged in one end of the second exhaust pipe 300 close to the first exhaust pipe 101, and the outer peripheral wall thereof is in sliding connection with the inner peripheral wall of the second exhaust pipe 300, and the activated carbon layer 602 is embedded in the porous mesh plate 601.

[0043] The structure of the second exhaust treatment layer 9011 is the same as that of the first exhaust treatment layer 600.

[0044] In the above embodiment, the volatile organic compounds (VOCs) and other harmful substances in the unorganized exhaust gas are adsorbed by the activated carbon layers in the first exhaust treatment layer 600 and the second exhaust treatment layer 9011, so as to remove the volatile organic compounds (VOCs) and other harmful substances in the material exhaust gas, thereby reducing the content of harmful substances in the unorganized exhaust gas entering the exhaust main pipe 500, and reducing the pressure of subsequent treatment of the unorganized exhaust gas entering the exhaust main pipe 500. In addition, the outer peripheral side of the porous mesh plate 601 is provided with a first sliding block / first sliding groove, and the inner peripheral side of the second exhaust pipe 300 and the first branch pipe 800 is provided with a first sliding groove / first sliding block corresponding to the porous mesh plate 601, and the sliding connection of the porous mesh plate 601 with the second exhaust pipe 300 and the first branch pipe 800 is realized by the cooperation of the first sliding block and the first sliding groove. The above-mentioned mode is only one possible implementation mode of the sliding connection of the porous mesh plate 601 with the second exhaust pipe 300 and the first branch pipe 800, and the specific sliding connection mode of the porous mesh plate 601 with the second exhaust pipe 300 and the first branch pipe 800 can be set according to actual needs, and the application does not make specific limitation thereon.

[0045] In some embodiments, referring to Figure 2The air inlet of the air inlet cover body 100 in the application is sequentially provided with a plurality of filter screen plates 102 with diameters decreasing from bottom to top, and the outer circumferential side of each filter screen plate 102 is in sliding connection with the inner circumferential wall of the air inlet cover body 100. The number of the filter screen plates 102 can be set according to actual needs, and the application does not make specific limitations thereon. In addition, the outer circumferential side of the filter screen plate 102 is provided with a second sliding block / second sliding groove, and the inner circumferential side of the air inlet cover body 100 is provided with a second sliding groove / second sliding block corresponding to the filter screen plate 102, and the sliding connection between the filter screen plate 102 and the air inlet cover body 100 is realized through the cooperation of the second sliding block and the second sliding groove. The above-mentioned mode is only one possible implementation mode of the sliding connection between the filter screen plate 102 and the air inlet cover body 100, and the specific sliding connection mode between the filter screen plate 102 and the air inlet cover body 100 can be set according to actual needs, and the application does not make specific limitations thereon.

[0046] In the above-mentioned embodiments, the filter screen plates 102 with diameters decreasing from bottom to top are arranged in the air inlet cover body 100 to realize the purpose of filtering the solid impurities entering the air inlet cover body 100, thereby avoiding the solid impurities entering the air inlet cover body 100 and the blockage of the pipeline by the solid impurities. The sliding connection between each filter screen plate 102 and the air inlet cover body 100 facilitates the installation and disassembly of the filter screen plate 102, thereby improving the convenience of cleaning the filter screen plate 102.

[0047] In some embodiments, referring to Figure 1 and Figure 2 The diameter of the air inlet cover body 100 in the application gradually decreases from bottom to top. Since the diameter of the air inlet cover body 100 is large at the bottom and small at the top, the unorganized waste gas of the unorganized waste gas generating device 200 can be quickly sucked into the air inlet cover body 100, and the unorganized waste gas is quickly gathered above the air inlet cover body 100 after entering the air inlet cover body 100, thereby improving the efficiency of the diffusion of the unorganized waste gas to the upper part of the air inlet cover body 100. The specific size of the air inlet cover body 100 can be set according to actual needs, and therefore the application does not make specific limitations thereon.

[0048] Finally, it should be noted that the above-mentioned embodiments are only used to illustrate the technical solutions of the application, but not to limit them. Although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent replacements for part or all of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application.
