Description

Technical Field

[0001] This utility model relates to the field of PVC sheet processing technology, and in particular to a waste gas treatment device for PVC sheet processing. Background Technology

[0002] During the processing of PVC sheets, high-temperature waste gas is generated. This waste gas usually has a strong pungent odor and its main components include solvent volatiles and other harmful gases. If this waste gas is discharged directly without treatment, it will harm the environment and human health. Therefore, a waste gas treatment device for PVC sheet processing is used.

[0003] To address this, patent CN215276507U discloses a high-temperature waste gas treatment device for PVC sheet processing, comprising a water tank, a filter box fixedly installed on the top of the water tank, and an aluminum box inside the water tank. The top of the aluminum box is fixedly installed on the top of the water tank, and the bottom of the aluminum box is fixedly installed on the bottom of the water tank. Multiple heat-conducting plates are fixedly installed on the outside of the water tank, and multiple heat-conducting fins are fixedly installed on each of the multiple heat-conducting plates. The top of the aluminum box is connected to the inside of the filter box, and the bottom of the filter box is filled with bamboo charcoal. The beneficial effects of this utility model are: this waste gas treatment device has a simple structure and is easy to use. The negative pressure generated by the fan rotation can accelerate the flow rate of the waste gas. Combined with the heat-conducting fins, the contact area with water is increased, heat dissipation is accelerated, and the working efficiency of waste gas treatment is further improved. At the same time, the above structure enables the exhaust seat to automatically exhaust, avoiding the problem of needing manual timed exhaust and saving labor.

[0004] Although the high-temperature waste gas treatment device mentioned above accelerates heat dissipation and further improves the efficiency of waste gas treatment, its low efficiency is due to the inconvenience of fixing it and replacing the activated carbon adsorption net regularly. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas treatment device for PVC sheet processing, which solves the problem that existing waste gas treatment devices for PVC sheet processing are inconvenient to fix.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste gas treatment device for PVC sheet processing, including a filter box and a sewage pipe;

[0007] A drain pipe is fixed to one side of the bottom of the filter box, and a box body is fixed to the other side of the bottom of the filter box. A filter screen is installed inside the box body. An air inlet pipe is fixed to the outer wall of the filter box above the drain pipe. A spray structure is provided on one side of the filter box.

[0008] The top of the filter box is provided with a fixing structure, which includes a support base, a reserved groove, a fixing frame and an activated carbon adsorption net. The support base is fixed to both sides inside the filter box. The reserved groove is evenly opened inside the support base. The fixed frame is provided inside the reserved groove. The activated carbon adsorption net is provided inside the fixing frame. A sealing door is provided on one side of the top of the filter box.

[0009] The top of the filter box is fixed with an exhaust hood, and the top of the exhaust hood is fixed with a protective structure.

[0010] When using this device, the fixed structure facilitates the replacement of the activated carbon adsorption mesh, thereby improving the working efficiency of the PVC sheet processing waste gas treatment device; the protective structure facilitates protection, thereby improving the ease of use; and the spray structure facilitates spraying, thereby improving the applicability of the PVC sheet processing waste gas treatment device.

[0011] Preferably, the protective structure includes an exhaust pipe, a cover, a protective net, and a handle. The exhaust pipe is fixed to the top of the exhaust hood. A cover is fitted onto the outer side of one end of the exhaust pipe. A protective net is provided on one side of the cover. Handles are fixed to both ends of one side of the cover. An external thread is provided on the outer side of one end of the exhaust pipe, and an internal thread is provided on the inside of the cover. The cover is rotated to the outside of the exhaust pipe using the handle.

[0012] Preferably, the outer side of one end of the exhaust pipe has external threads, and the inside of the cover has internal threads. The protective mesh prevents impurities from entering the filter box. By rotating the cover with the handle, the cover and exhaust pipe can be separated, facilitating cleaning of the protective mesh.

[0013] Preferably, the spray structure includes a water tank, an inlet pipe, a delivery pump, a return pipe, a first diverter seat, a delivery pipe, a second diverter seat, and atomizing nozzles. The water tank is located on one side of the filter box. An inlet pipe is fixed to one side of the top of the water tank. A delivery pump is installed at the bottom of the water tank. A delivery pipe is fixed to the output end of the delivery pump. A return pipe is fixed to one side of the bottom of the water tank. Second diverter seats are fixed to both sides inside the filter box. Atomizing nozzles are evenly fixed to one side of each second diverter seat. First diverter seats are fixed to the outer wall of the filter box at one end of each second diverter seat.

[0014] Preferably, the end of the return pipe furthest from the water tank is connected to one side of the tank body, and the end of the delivery pipe furthest from the delivery pump is connected to one side of the first diverter seat. Under the action of the delivery pump, water from inside the water tank enters the interior of the first diverter seat through the delivery pipe, and water from the first diverter seat enters the interior of the second diverter seat and is then sprayed out through the atomizing nozzle. This allows harmful substances such as particulate matter and dust in the exhaust gas to be captured and settled by the water mist, effectively removing solid pollutants from the exhaust gas while also having a cooling effect.

[0015] Preferably, one end of the second diverter is connected to one side of the first diverter, and the atomizing nozzles are evenly distributed on one side of the second diverter. Water at a higher level inside the filter box enters the box and is filtered through a filter screen. The filtered water returns to the inside of the water tank through a return pipe, thus saving water resources. Wastewater at a lower level inside the filter box is discharged through a drain pipe.

[0016] Preferably, the fixed frame and the support base form a sliding structure through a pre-reserved groove, with one side of the fixed frame contacting one side of the sealing door panel. Opening the sealing door panel allows the fixed frame to be moved into the filter box. Pushing the fixed frame further moves it into the pre-reserved groove. Closing the sealing door panel brings one side of the sealing door panel into contact with one side of the fixed frame. The sealing door panel's limiting action prevents displacement of the fixed frame. Under the action of the activated carbon adsorption mesh, harmful gas molecules in the exhaust gas are effectively adsorbed. After treatment by the atomizing nozzle, residual organic matter is further removed.

[0017] The present invention provides a waste gas treatment device for PVC sheet processing, the advantages of which are:

[0018] By setting a fixed structure, opening the sealing door, moving the fixed frame into the filter box, pushing the fixed frame into the reserved slot, and closing the sealing door so that one side of the sealing door contacts one side of the fixed frame, the fixed frame is prevented from shifting under the limiting action of the sealing door. Under the action of the activated carbon adsorption net, harmful gas molecules in the exhaust gas can be effectively adsorbed. After being treated by the atomizing nozzle, residual organic matter is further removed. This device realizes the function of easy replacement of activated carbon adsorption net, thereby improving the working efficiency of the exhaust gas treatment device for PVC board processing.

[0019] By setting up a protective structure, an external thread is opened on the outside of one end of the exhaust pipe, and an internal thread is opened on the inside of the cover. By rotating the cover to the outside of the exhaust pipe with the handle, impurities are prevented from entering the filter box under the action of the protective net. By rotating the cover with the handle, the cover and the exhaust pipe are separated from each other, making it convenient to clean the protective net. This realizes the protective function of the device, thereby improving the convenience of using the waste gas treatment device for PVC board processing.

[0020] By incorporating a spray structure, water from the tank is pumped through a delivery pipe into the first diversion seat by a pumping unit. The water from the first diversion seat then enters the second diversion seat and is sprayed out through atomizing nozzles. This process captures and settles particulate matter, dust, and other harmful substances in the exhaust gas, effectively removing solid pollutants and providing a cooling effect. This facilitates the spraying process and improves the applicability of the exhaust gas treatment device for PVC board processing. Attached Figure Description
