Description

Technical Field

[0001] The invention belongs to the technical field of waste gas from protective membranes, and in particular relates to an organic polymer reaction waste gas purification device for producing protective membranes. Background Art

[0002] Protective film is made from polyethylene granules. During production, the film is first blown through a film blowing machine to form a raw film, then coated with glue by a coater. Finally, it is wound, slit, and packaged at the end of the machine, creating the well-known protective film. During the production and preparation of polyethylene raw materials, a large number of additives, such as colorants, antioxidants, anti-blocking agents, UV inhibitors, and lubricants, are added. However, during the hot-melt blowing of polyethylene raw materials, the heat and shearing inside the extruder cause the additives to release low-molecular gases. These volatile gases are harmful to the human body. The odor released during polyethylene hot processing is caused by the release of volatile organic compounds (VOCs). VOCs are a group of chemicals that evaporate easily at room temperature. Some VOCs, such as styrene, ethylbenzene, and formaldehyde, are considered harmful to human health. Furthermore, the heating and melting of additives can easily generate certain harmful gases, which, when directly released into the air, can harm the atmospheric environment. Therefore, large-scale exhaust gas purification equipment is currently required to collect and purify these exhaust gases.

[0003] Waste gas purification mainly refers to the work of treating industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases. Waste gases emitted by industrial production often have harmful effects on the environment and human health. Purification measures should be taken before they are discharged into the atmosphere to make them meet the requirements of waste gas emission standards. This process is called waste gas purification.

[0004] The existing technology for purifying waste gas has the following disadvantages: 1. Existing exhaust gas purification devices usually filter exhaust gas through filters and spraying to reduce dust. After spraying, wastewater containing flue gas is mostly discharged directly. In a certain sense, the flue gas is not just gas, but also dust particles physically. It is solid and can float in the air because of its light weight. When the spray liquid is used to treat the dust in the flue gas, it is not convenient to recycle and reuse the wastewater after subsequent treatment, resulting in unnecessary waste of resources.

[0005] 2. Currently, when filtering and adsorbing dust and harmful substances in exhaust gas, the filter plate needs to be replaced regularly. When reinstalling the filter plate after removal, it is preferred to align the filter plate with the housing mounting hole. When the filter plate is inserted into the housing, it is necessary to keep the filter plate level. When the filter plate is in a higher or lower position, the operator is in an uncomfortable state. It is inconvenient to insert the filter plate into the housing while keeping the filter plate level. The filter plate is very easy to be skewed during the insertion process, and the skewness will make it difficult to insert, which increases the inconvenience of removing and installing the filter plate. Summary of the Invention

[0006] The purpose of the present invention is to provide an organic polymer reaction waste gas purification device for making protective films. Its advantages are that it can replace the inconvenience caused by the skew of the filter plate during manual plug-in installation, bring convenience to the use of the device and the operation of the operator. At the same time, it can extend the service life of the filter plate, reduce the tediousness and inconvenience of frequent replacement of the filter plate, and is different from the existing shutdown operation of replacing the filter plate, so as to reduce the impact on the purification efficiency caused by the shutdown maintenance of the device.

[0007] The above technical purpose of the present invention is achieved through the following technical solutions: an organic polymer reaction waste gas purification device for making protective films, including a housing structure. The housing structure includes a housing. An installation structure is provided inside the housing. The installation structure includes a filtering component and a moving component. The filtering component includes a polymer filter plate, a honeycomb activated carbon filter plate and a filter plate. The moving component includes a screw rod and a first guide rod. The screw rod and the first guide rod are respectively located at both ends of the polymer filter plate, the honeycomb activated carbon filter plate and the filter plate. A cleaning structure is provided at the top of the filter plate. The cleaning structure includes a scraping component and a reciprocating component. The scraping component includes a first rod body. The reciprocating component includes a waterproof motor.

[0008] With the above technical solution, when it is necessary to react and purify the waste gas during the production of the protective film, the intake pipe is connected to the waste gas, and the waste gas will enter the interior of the housing through the intake pipe. The liquid inlet pipe is connected to the external spraying liquid supply equipment capable of treating the waste gas, and then it will be distributed to the spray heads one by one through the pipeline and finally sprayed down. At this time, the waste gas comes into contact with the spraying liquid, and the waste gas initially treated by the spraying liquid will be adsorbed and filtered by the honeycomb activated carbon filter plate and the polymer filter plate in turn as it rises, helping to purify the waste gas. The sprayed spraying liquid will be filtered by the filter plate to filter the spraying liquid adsorbed with impurities such as dust. At this time, when it is necessary to replace and disassemble the honeycomb activated carbon filter plate, the polymer filter plate or the filter plate, the honeycomb activated carbon filter plate, the polymer filter plate or the filter plate can be taken out through the setting of the moving component, and then the operator holds the handle to catch the honeycomb activated carbon filter plate, the polymer filter plate or the filter plate. When it is necessary to install a new honeycomb activated carbon filter plate, a polymer filter plate or a filter plate, take the corresponding handle and the end cover, and through the reverse rotation of the moving component, the installation and insertion of the honeycomb activated carbon filter plate, the polymer filter plate or the filter plate into the housing can be realized. Through this setting, the inconvenience caused by the skew of the filter plate in the manual plug-in installation can be replaced. The operator only needs to horizontally support the filter plate to be installed, and there is no need to achieve plug-in while maintaining horizontal as in the existing installation, because the plug-in process is very likely to be skewed, and this structure brings convenience to the use of the device and the operation of the operator. And during the reaction and purification of the waste gas, when the filter plate is saturated with filtration, the reciprocating component can drive the scraping component to move, so that the scraper scrapes the impurities on the filter plate, and the impurities are driven into the receiving groove through the movement of the scraper, realizing the cleaning of the filter plate. Through this setting, the service life of the filter plate can be increased, the cumbersome and inconvenient frequent replacement of the filter plate can be reduced, and at the same time, the scraping of the scraper can be carried out during the purification process, which is different from the shutdown operation of replacing the filter plate in the existing situation, achieving the reduction of the impact on the purification efficiency caused by the shutdown maintenance of the device.

At this time, through the settings of the first connecting plate 3025, the second connecting plate 3026 and the third rod body 3027, the reciprocating movement of the first rod body 3011 and the cross bar 3012 on the second guide rod 3015 is realized. The fixing block 3028 supports the third rod body 3027.

[0037] Brief description of the usage process: During the reaction purification of waste gas, when the filter plate 2013 becomes saturated with filtration, the operation of the waterproof motor 3021 can drive the rod body two 3022 and the transmission gear one 3023 to rotate. The transmission gear one 3023 will drive the transmission gear two 3024 and the rod body one 3011 to rotate. The rod body one 3011 will drive the connecting plate one 3025 to rotate. At this time, the connecting plate one 3025 will, through the settings of the connecting plate two 3026 and the rod body three 3027, achieve the reciprocating movement of the rod body one 3011 and the cross bar 3012 on the guide rod two 3015. The fixed block 3028 supports the rod body three 3027. The movement of the cross bar 3012 will be guided by the guide rod two 3015. The cross bar 3012 will synchronously drive the scraper 3013 to move. The scraper 3013 scrapes the impurities on the filter plate 2013 and drives the impurities into the receiving groove 3017 through the movement of the scraper 3013, realizing the cleaning of the filter plate 2013, improving the service life of the filter plate 2013, reducing the replacement frequency of the filter plate 2013. At the same time, when the scraper 3013 needs to be replaced, the disassembly of the bolt 3016 can be used to achieve the disassembly and replacement of the mounting plate 3014 and the cross bar 3012. The reciprocating assembly 302 drives the scraping assembly 301 to move, so that the scraper 3013 scrapes the impurities on the filter plate 2013 and drives the impurities into the receiving groove 3017 through the movement of the scraper 3013, realizing the cleaning of the filter plate 2013. Through this setting, the service cycle of the filter plate 2013 can be improved, reducing the cumbersome and inconvenient frequent replacement of the filter plate 2013. At the same time, the scraping operation of the scraper 3013 can be carried out during the purification process, different from the existing shutdown operation of replacing the filter plate 2013, achieving a reduction in the impact on the purification efficiency caused by the shutdown maintenance of the device.
