[0002] With the rapid development of industry and technology in recent years, the disadvantages brought by rapid development have gradually emerged. Among them, the more serious problems are resource problems and environmental problems. In order to reduce the environmental problems caused by pollution, the country has begun to vigorously promote green environmental protection, energy conservation and emission reduction. After that, photovoltaic power generation has gradually emerged. However, in the process of manufacturing photovoltaic glass, it is inevitable to produce organic waste gas containing silicon vosc. Organic waste gas is a highly volatile organic matter that will seriously endanger humans and the environment. Therefore, the vosc waste gas needs to be treated before it can be discharged. However, in the process of treatment, the concentrated discharge of waste gas will cause a large amount of waste gas to be discharged without complete contact with the treatment liquid, resulting in the treatment effect is not obvious. Utility Model Content

[0003] The utility model aims to provide a treatment device for silicon-containing VOCs waste gas from photovoltaic glass, so as to solve the problem in the above background technology that the gas is too concentrated and cannot be completely contacted with the treatment liquid, resulting in unclear treatment effect.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a treatment device for silicon-containing VOCs waste gas from photovoltaic glass, comprising a treatment box, an air inlet is installed through the outer surface of the treatment box, and an exhaust port is installed through the outer surface of the treatment box at one end away from the treatment box, a liquid storage box is fixedly installed on the side surface of the treatment box, and an observation window is inlaid on the outer surface of the liquid storage box at one side away from the treatment box, a pull-out plate is slidably installed on the side surface of the treatment box, and a sealing rubber gasket is arranged between the pull-out plate and the treatment box, and the treatment box and the pull-out plate are fixed by bolts, and a rotating sliding mechanism is arranged between the liquid storage box and the treatment box, and the adsorption solution stored in the liquid storage box is sprayed out by the rotating sliding mechanism so that the solution can be more fully in contact with the waste gas.

[0005] Preferably, the rotating and sliding mechanism includes: a driving motor, the driving motor is fixedly mounted on the outer surface of the liquid storage box, and a cam is fixedly mounted on the output shaft of the driving motor, and a groove is opened inside the cam, a pump housing is fixedly mounted inside the liquid storage box, and a piston is slidably mounted inside the pump housing, and the piston and the pump housing are connected by sliding friction, one end of the piston passes through the outer surface of the liquid storage box, and the piston at one end outside the liquid storage box is engaged with the groove of the cam, and the cam and the piston are slidably connected, and a one-way valve is fixedly mounted on the input and output ends of the pump housing.

[0006] By adopting the above technical scheme, the cam is driven to rotate by the rotation of the driving motor, so that the cam drives the piston to slide up and down inside the pump housing, and when the cam drives the piston to rise, the treatment liquid inside the liquid storage tank is sucked into the interior of the pump housing. Then, the cam drives the piston to descend so that the treatment liquid is pressed out of the pump housing, enters the atomizing spray disc and is sprayed into the interior of the treatment box, so that the gas to be treated in the treatment box can fully contact with the atomized treatment liquid, thereby improving the efficiency of treatment and absorption.

[0007] Preferably, the bottom of the liquid storage box is designed to be inclined, and the lowest side of the liquid storage box is away from the injection port of the liquid storage box, and the lowest point of the liquid storage box is the input end installation point of the pump casing, and the bottom of the processing box is designed to be symmetrically inclined, and a drain port is provided on one side of the processing box close to the air inlet, and the drain port of the processing box is located at the lowest point.

[0008] By adopting the above technical solution, through the inclined design of the bottom of the liquid storage tank, after the treatment liquid is injected, the treatment liquid will always flow to the lowest point of the liquid storage tank, so that the input end of the pump housing can always absorb the treatment liquid, and at the same time, the remaining amount of treatment liquid can be timely observed through the observation window on the side of the liquid storage tank, and the inclined design of the bottom of the processing tank can make the treatment liquid after treatment and adsorption be discharged from the processing tank along the inclined surface.

[0009] Preferably, a section of the air inlet located inside the processing box is designed to be inclined, and a gas dispersion plate is fixedly installed at one end of the air inlet, and the gas dispersion plate faces the direction of the liquid storage box.

[0010] By adopting the above technical solution, the waste gas sent into the processing box can be more dispersed through the gas dispersion plate, so that the atomized processing liquid can contact with the waste gas more fully.

[0011] Preferably, a transmission mechanism is provided between the liquid storage box and the driving motor, and the atomized treatment liquid can be sprayed more evenly inside the treatment box through the transmission mechanism.

[0012] By adopting the above technical solution, the atomizing spray disc inside the processing box can be rotated to increase the spray range of the processing liquid.

[0013] Preferably, the transmission mechanism includes: a second pulley, the second pulley is fixedly mounted on the outer surface of the output shaft of the driving motor, and the second pulley is located between the cam and the driving motor, the outer surface of the liquid storage box is penetrated by the output end of the pump casing, and the output end of the pump casing is rotatably mounted with an atomizing spray disc, and one end of the atomizing spray disc penetrates the side surface of the processing box, the processing box and the atomizing spray disc are rotationally frictionally connected, and the outer surface of the atomizing spray disc is fixedly mounted with a first pulley, and a belt is arranged between the first pulley and the second pulley.

[0014] By adopting the above technical scheme, the second pulley is driven to rotate by the rotation of the driving motor, so that the belt drives the first pulley to rotate. At the same time, the diameter difference between the first pulley and the second pulley can reduce the rotation speed of the atomizing spray disc, so that the treatment liquid sprayed by the atomizing spray disc after atomization can be sprayed farther, and the treatment liquid can be sprayed while the atomizing spray disc rotates.

[0015] Preferably, a sliding baffle plate is fixedly installed at one end of the processing box away from the air inlet, and the sliding baffle plate is respectively provided with openings, a supporting frame is fixedly installed on the side surface of the pull-out plate, and the side surface of the supporting frame is in contact with the side surface of the sliding baffle plate, and a filter adsorption plate is slidably installed inside the supporting frame, and the filter adsorption plate is in contact with the outer surfaces of both sides of the processing box.

[0016] By adopting the above technical solution, the time for the treated exhaust gas to pass can be extended by designing the sliding baffle plate, and the exhaust gas can be filtered again by the filter adsorption sheet in the supporting frame, so that the harmful substances in the exhaust gas passing through can reach lower standards.

[0017] Compared with the prior art, the beneficial effects of the utility model are: the device for treating silicon-containing VOCs waste gas from photovoltaic glass:

[0018] 1. The waste gas to be treated is discharged into the treatment box through the air inlet, and then the cam is driven to rotate by the rotation of the driving motor, and the piston engaged with the cam is pulled to slide inside the pump housing. With the one-way valve, when the piston is pulled up by the cam, the treatment liquid is sucked into the pump housing, and then the piston is pressed down by the cam, so that the treatment liquid is discharged from the pump housing and sprayed into the treatment box through the atomization of the atomizing spray disc, so as to increase the contact area between the treatment liquid and the waste gas and improve the treatment effect of the waste gas;

[0019] 2. When the cam rotates, the second pulley will rotate along with it, and the first pulley will rotate along with it through the belt, so that the atomizing spray disc rotates, so that the atomizing spray disc can spray the atomized treatment liquid in a large area in the treatment box. The diameter difference between the second pulley and the first pulley can reduce the rotation speed of the atomizing spray disc, so that the atomizing spray disc will not rotate too fast and fail to spray the atomized treatment liquid farther, so that the atomizing spray disc automatically absorbs the treatment liquid while rotating;

[0020] 3. After the gas is adsorbed by the treatment liquid, it will pass through the sliding barrier plates, so that the gas cannot be discharged directly and quickly from the treatment box. Through the inserted carrying frame, the gas can only pass through the filter adsorption sheet inside the carrying frame. At the same time, the pull-out plate can be pulled out, and the carrying frame can be taken out of the treatment box. The filter adsorption sheet in the carrying frame can be replaced. The gas can be filtered again through the filter adsorption sheet to reduce the harmful substances mixed in the gas, so that the content of harmful substances in the treated gas is lower.

[0030] When the exhaust gas needs to be treated, the exhaust gas can be discharged into the interior of the treatment box 1 through the air inlet 2, and then the drive motor 5 is started. The rotation of the drive motor 5 drives the cam 7 to rotate, so that the cam 7 drives the piston 12 to slide up and down inside the pump housing 13. In conjunction with the one-way valve 14, the piston 12 sucks the treatment liquid into the pump housing 13 when it rises, and pushes the treatment liquid out of the pump housing 13 as the piston 12 descends, so that the pushed treatment liquid is sprayed out from the atomizing spray disc 11, so that the contact area between the exhaust gas and the treatment liquid becomes larger, thereby improving the adsorption efficiency of the treatment liquid.

[0036] The rotation of the driving motor 5 can make the second pulley 8 rotate together, and the rotation of the second pulley 8 can make the belt 10 drive the first pulley 9 to rotate, so that the atomizing spray disc 11 can rotate, and the atomized treatment liquid sprayed by the atomizing spray disc 11 can be evenly dispersed in the treatment box 1. The diameter difference between the second pulley 8 and the first pulley 9 can reduce the rotation speed of the atomizing spray disc 11, so that the sprayed atomized liquid can be sprayed farther, and the atomizing spray disc 11 can rotate and spray the atomized treatment liquid at the same time.

[0037] A sliding baffle plate 17 is fixedly installed at one end of the processing box 1 away from the air inlet 2, and the sliding baffle plate 17 is respectively provided with openings, a supporting frame 16 is fixedly installed on the side surface of the pull-out plate 15, and the side surface of the supporting frame 16 is in contact with the side surface of the sliding baffle plate 17, and a filter adsorption sheet 18 is slidably installed inside the supporting frame 16, and the filter adsorption sheet 18 is in contact with the outer surfaces of both sides of the processing box 1.

[0038] After the gas is adsorbed by the treatment liquid, the exhaust gas will pass through the sliding baffle plate 17 and move horizontally inside the treatment box 1 to extend the time for the gas to pass through. At the same time, the supporting frame 16 inserted into the sliding baffle plate 17 can fix the filter adsorption sheet 18 between the sliding baffle plates 17. At the same time, the supporting frame 16 can be pulled out through the pull-out plate 15 to replace the filter adsorption sheet 18, so that the treated gas can be filtered again through the filter adsorption sheet 18, and the harmful impurities in the gas can be filtered again, so that the harmful substances discharged through the exhaust port 3 can be less, and the gas can be treated more cleanly.
