Description

Technical Field

[0001] The present invention belongs to the technical field of chemical waste gas purification, and specifically relates to a waste gas treatment device for plastic production. Background Art

[0002] Plastic generally uses various chemical plastic raw materials such as polyethylene and polypropylene. A large amount of harmful gases will be generated during the production process of plastic woven bags. If directly discharged, it will cause environmental pollution. Before discharging the waste gas, purification treatment is required to reduce environmental pollution. When the generated waste gas is discharged, most of it is adsorbed by high-efficiency activated carbon to remove harmful substances in the waste gas, thereby purifying the waste gas.

[0003] A patent with the publication number CN116920568B discloses a waste gas treatment device for plastic woven bag production, including a conveying mechanism, a purification mechanism installed on the conveying mechanism, a protection mechanism installed on the purification mechanism, a clamping mechanism installed on the purification mechanism, a locking mechanism installed on the purification mechanism, a sealing mechanism installed on the purification mechanism, and a filtering mechanism installed at the bottom of the conveying mechanism; through the installation of multiple purification mechanisms and the conveying mechanism, it is beneficial for waste gas purification treatment. Through the control of the protection mechanism by the purification mechanism, it is beneficial to prevent a large amount of waste gas from escaping when replacing the adsorption material. Through the clamping mechanism, it is convenient to disassemble and assemble the adsorption material. Through the locking mechanism, the purification mechanism is firmly installed. Through the locking mechanism driving the sealing mechanism to work, it is beneficial to seal between the purification mechanism and the conveying mechanism. Through the filtering mechanism, it is beneficial to preliminarily filter the conveying mechanism and facilitate subsequent cleaning.

[0004] Currently, in the existing technology, high-efficiency activated carbon is used to adsorb harmful substances in plastic waste gas during the purification process. However, the waste gas has a certain temperature and large particulate impurities during production. When the continuously flowing waste gas passes through one end of the high-efficiency activated carbon, the inlet of the high-efficiency activated carbon will be blocked. At this time, employees need to stop the equipment and replace the current high-efficiency activated carbon. Stopping the equipment to replace the high-efficiency activated carbon also wastes a lot of time, and the filtering time of each piece of high-efficiency activated carbon is relatively short, and the problem of being unable to increase the waste gas filtering time.

[0017] The beneficial effects of the present invention are as follows: 1. For the plastic production waste gas treatment equipment of the present invention, when the waste gas passes through the first air hole, it will quickly pass through the activated carbon cylinder, and the high-efficiency activated carbon inside the activated carbon cylinder is used to purify the waste gas. After one activated carbon cylinder works for two hours, the motor is used to rotate the rotating disk, and the activated carbon cylinder at one side edge position of the first air hole is replaced, so that the new activated carbon cylinder is re-docked at the outlet of the first air hole, and then multiple activated carbon cylinders are continuously docked at the inlet of the first air hole, so that the waste gas can always maintain the best purification effect; 2.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0022] As Figures 1 to 3 、 Figure 6 - Figure 9 shown, a waste gas treatment device for plastic production in an embodiment of the present invention includes a first support frame 11 and a waste gas treatment box 12 fixedly installed on the outer surface of the top of the first support frame 11. An activated carbon purification box 15 is detachably installed on the inner wall surface of the waste gas treatment box 12. A first baffle 154 is fixedly installed on the inner wall surface of the activated carbon purification box 15. A first air hole 155 is opened at the top edge position of the first baffle 154. A motor 156 is fixedly installed on one side surface of the activated carbon purification box 15. The output end of the motor 156 extends to the inner wall surface of the activated carbon purification box 15. A rotating disk 157 is fixedly installed on the outer surface of the output end of the motor 156. A plurality of activated carbon cylinders 158 are arranged inside the rotating disk 157. High-efficiency activated carbon is filled inside the activated carbon cylinders 158. A third support frame a1 is fixedly installed on one side surface of the first baffle 154. The second baffle a4 is movably overlapped on the inner wall surfaces on both sides of the activated carbon cylinder 158.

[0023] When the waste gas passes through the first air hole 155, it will quickly pass through the activated carbon cylinder 158, and the high-efficiency activated carbon inside the activated carbon cylinder 158 is used to purify the waste gas. After an activated carbon cylinder 158 works for two hours, the motor 156 is used to rotate the rotating disk 157, and the activated carbon cylinder 158 at the edge position on one side of the first air hole 155 is replaced, so that the new activated carbon cylinder 158 is re-docked at the outlet of the first air hole 155. Then, multiple activated carbon cylinders 158 are continuously docked at the inlet of the first air hole 155, so that the waste gas can always maintain the best purification effect, avoiding the situation that there is only one piece of traditional high-efficiency activated carbon. As a result, due to the accumulation of impurity particles on the surface of the input end of the high-efficiency activated carbon during long-term filtration and purification, the high-efficiency activated carbon will be blocked, resulting in the subsequent waste gas being unable to effectively pass through the high-efficiency activated carbon.

[0024] As Figure 8 - Figure 9 shown, a gauze a6 is provided at the middle position of the second baffle a4, air holes a5 are opened on the outer surface of the second baffle a4, and a hydraulic pump a2 is fixedly connected to the output end of the third support frame a1; When the waste gas flows, the hydraulic pump a2 on the outer surface of the third support frame a1 is extended and the output end of the hydraulic pump a2 is lapped on the outer surface of the second baffle a4. As the hydraulic pump a2 extends continuously, the high-efficiency activated carbon is slightly compressed, so that the gaps between the loose high-efficiency activated carbons can be made tighter, increasing the close and sufficient contact between the waste gas and the high-efficiency activated carbon. Utilizing the highly developed pore structure and huge specific surface area on the surface of the activated carbon, it can adsorb volatile organic compounds in the plastic waste gas and adsorb the organic molecules in the waste gas into the pores of the activated carbon, thus achieving the effect of purifying the plastic waste gas.

[0025] As Figure 7 - Figure 8 shown, the output end of the activated carbon purification box 15 is movably lapped on the outer surface of the first baffle 154, the outer surface of the rotating disk 157 is movably lapped on the outer surface of the first baffle 154, and two air pipes 151 are fixedly installed on both side surfaces of the activated carbon purification box 15 and at the top edge position. One-way valves two 152 are fixedly installed on the inner wall surfaces of the two groups of air pipes 151.

[0026] The one-way valve two 152 inside the air pipe 151 is used to conduct one-way drainage of the input waste gas, effectively control the amount of waste gas flowing each time, and utilize the cavity between multiple first baffles 154 to conduct segmented aggregation of the waste gas, and conduct segmented filtration and purification treatment on the waste gas after segmented aggregation under the drainage of the gas.

[0027] As Figure 1 - Figure 4 and Figure 6- Figure 7 As shown, a power unit is fixedly connected to the top surface of the support frame 11 and located at the edge position of one side, and the power unit includes a support frame 2 14, and a sealing box 13 is fixedly installed on the top surface of the exhaust gas treatment box 12; two groups of hydraulic rods 141 are fixedly installed on the bottom surface of the support frame 2 14, and an exhaust gas suction tank 142 and a cleaning tank 144 are fixedly installed on the top surface of the support frame 1 1, respectively, and a lower pressure plate 147 movably overlapped on the inner wall surface of the exhaust gas suction tank 142 and the cleaning tank 144 is fixedly installed on the output end of the two groups of hydraulic rods 141, and two groups of circulation pipes 143 are fixedly installed on the two side surfaces of the exhaust gas suction tank 142 and located at the top edge position, and the inner wall surface of the circulation pipe 143 is fixedly installed There is a one-way valve 146, the other end of the circulation pipe 143 is connected to the output end of a group of air pipes 151, and a circulation water pipe 145 is fixedly installed on the two side surfaces of the cleaning tank 144 and at the bottom edge position, and the other end of the circulation water pipe 145 extends to the inner wall of the exhaust gas treatment box 12, and the interior of the cleaning tank 144 is filled with clean water; a wastewater return device 112 is fixedly installed on the bottom surface of the support frame 11, and an air guide pipe 111 is fixedly connected to the output end of the wastewater return device 112, and a double-hole fork is provided at one end of the air guide pipe 111, and the two ends of the double-hole fork extend to the inner wall of the exhaust gas extraction tank 142 and the exhaust gas treatment box 12 respectively, and a water hole 153 is opened on the bottom surface of the activated carbon purification box 15.

[0028] After the exhaust gas is purified, the one-way valve 146 inside the circulation pipe 143 is closed, and the clean water inside the cleaning tank 144 is poured into the exhaust gas treatment box 12 through the circulation water pipe 145, and the clean water fills half of the space inside the activated carbon purification box 15. As the liquid is continuously filled, the clean water will penetrate into the activated carbon purification box 15 through the water hole 153. When the water source can completely soak the high-efficiency activated carbon, the motor 156 is used to rotate the rotating disk 157 and the activated carbon cylinder 158. At this time, the fluffy high-efficiency activated carbon will be turned over, rubbed, and squeezed with the rotation of the activated carbon cylinder 158, and some impurity particles adhering to the outer surface of the high-efficiency activated carbon will be cleaned off during the turning process; Under the continuous up and down squeezing of the lower pressure plate 147, the water source inside the waste gas treatment box 12 will continuously be flushed inside the waste gas treatment box 12 and the activated carbon purification box 15. With each extraction of the water source, the impurities inside the fluffy and efficient activated carbon will be extracted under the guidance of the water source. After the water source is extracted, the rotating disk 157 is rotated at high speed by the motor 156 to discharge the residual water source inside the efficient activated carbon, and then the residual sewage in the air guide pipe 111 is extracted and filtered through the wastewater return device 112, and the filtered water source is re-directed into the interior of the cleaning tank 144 through the circulating water pipe 145 for secondary utilization.

[0029] like Figure 1 , Figure 3 - Figure 5 , Figure 8 - Figure 9 As shown, a condensation box 131 is fixedly installed on the inner wall of the sealed box 13, a condensation pipe 135 is fixedly installed on the upper and lower inner wall surfaces of the condensation box 131, the bottom end of the condensation pipe 135 extends to the top inner wall of the exhaust gas treatment box 12, a jet strip 134 is fixedly installed on the top of the condensation pipe 135, a condensation air pipe 132 is fixedly installed on the two side surfaces of the condensation box 131, the other end of the condensation air pipe 132 is fixedly installed with a coolant tank 133 arranged on the top surface of the exhaust gas treatment box 12, and an aluminum tube a3 is fixedly installed on the inner wall of the activated carbon tube 158.

[0030] In conjunction with the coolant tank 133, the coolant is injected into the internal circulation of the condenser box 131, and the coolant will rapidly cool down the surface of the condenser tube 135. At this time, the air inside the aluminum tube a3 is circulating, and the air will penetrate the inner wall of the condenser tube 135. The rising air will retain a certain heat source. Due to the temperature difference, the hot air and the low-temperature cold air inside the condenser tube 135 will quickly interact in temperature, thereby achieving the effect of rapidly cooling the air.

[0031] like Figure 1 - Figure 3 As shown, a lap support plate 123 is fixedly installed on the inner wall of the exhaust gas treatment box 12, and the activated carbon purification box 15 is positioned on the inner wall of the lap support plate 123. A filter plate 121 arranged on an edge position of one side of the lap support plate 123 is fixedly connected to the inner wall of the exhaust gas treatment box 12, and the outer surface of the jet strip 134 is movably overlapped on the top surface of the filter plate 121. An exhaust gas inlet 122 is provided on one side surface of the exhaust gas treatment box 12 and at an edge position of one side of the filter plate 121.

[0032] Cooperate with the waste gas input port 122 to inject the plastic waste gas after production into the waste gas treatment box 12, and make the high-temperature waste gas accumulate preferentially in the waste gas treatment box 12, and cooperate with the filter plate 121 on the inner wall of the waste gas treatment box 12 to filter the plastic waste gas. With the flow of gas, the high-temperature waste gas is injected into the activated carbon purification box 15, and the plastic waste gas is continuously filtered and purified by the high-efficiency activated carbon inside the activated carbon purification box 15, and the purified waste gas is discharged in one direction, so as to achieve the effect of injecting and discharging the purified plastic waste gas.

[0033] Working principle: cooperate with the waste gas input port 122 to inject the plastic waste gas after production into the waste gas treatment box 12, and make the high-temperature waste gas accumulate in the waste gas treatment box 12 first, and cooperate with the filter plate 121 on the inner wall of the waste gas treatment box 12 to filter the plastic waste gas. With the flow of gas, the high-temperature waste gas is injected into the activated carbon purification box 15, and the plastic waste gas is continuously filtered and purified by the high-efficiency activated carbon inside the activated carbon purification box 15. Then, the one-way valve 146 on the inner wall of the circulation pipe 143 is used to discharge the purified waste gas in one direction, so as to achieve the effect of injecting and discharging the purified plastic waste gas; When the waste gas flows, the pore 155 on the outer surface of the baffle 154 guides the waste gas into the inside of the activated carbon cylinder 158, and at the same time, the hydraulic pump a2 on the outer surface of the support frame a1 is extended and the output end of the hydraulic pump a2 is overlapped on the outer surface of the baffle a4. As the hydraulic pump a2 continues to extend, the high-efficiency activated carbon inside the activated carbon cylinder 158 is slightly compressed, so that the gap between the loose high-efficiency activated carbon can be more compact, and the waste gas and the high-efficiency activated carbon can be closely and fully contacted together. The highly developed pore structure and huge specific surface area of the activated carbon surface can be used to adsorb volatile organic compounds in the plastic waste gas, and adsorb organic molecules in the waste gas into the pores of the activated carbon, thereby achieving the effect of purifying the plastic waste gas; After the exhaust gas passes through the air hole 155, it will quickly pass through the activated carbon cartridge 158, and the exhaust gas will be purified by the high-efficiency activated carbon inside the activated carbon cartridge 158. After one activated carbon cartridge 158 works for two hours, the motor 156 is used to rotate the rotating disk 157, and the activated carbon cartridge 158 on the edge of one side of the air hole 155 is replaced, so that the new activated carbon cartridge 158 is re-connected to the outlet of the air hole 155, and then multiple activated carbon cartridges 158 are continuously connected to the inlet of the air hole 155, so that the exhaust gas can always maintain the effect of the best purification degree, avoiding the traditional high-efficiency activated carbon with only one piece, so that the high-efficiency activated carbon will be blocked on the input end surface due to the accumulation of impurity particles under long-term filtration and purification, so that the subsequent exhaust gas cannot effectively pass through the high-efficiency activated carbon; After the exhaust gas is extracted, the residual heat inside the plastic exhaust gas will remain inside the high-efficiency activated carbon, and through the heat-conducting material characteristics of the aluminum cylinder tube a3, the residual heat inside the high-efficiency activated carbon is transferred to the inside of the aluminum cylinder tube a3, and the hydraulic rod 141 is used to move the lower pressing plate 147 up and down. When the lower pressing plate 147 moves upward inside the exhaust gas extraction tank 142, air pressure will be generated inside the exhaust gas extraction tank 142 and at the bottom of the lower pressing plate 147, and the gas inside the exhaust gas treatment box 12 is extracted downward through the air duct 111. As the air passes through the aluminum cylinder tube a3, the residual heat inside the aluminum cylinder tube a3 is absorbed and discharged, and under the continuous heat absorption of the aluminum cylinder tube a3, the residual heat inside the high-efficiency activated carbon is continuously dissipated; Cooperate with the coolant tank 133 to circulate and pour the coolant into the inside of the condensation box 131. The coolant will rapidly cool the surface of the condensation pipe 135. At this time, when the air inside the aluminum cylinder tube a3 circulates, when the air passes through the inner side wall surface of the condensation pipe 135, the rising air will have a certain heat source. Under the temperature difference, the hot air and the low-temperature cold air inside the condensation pipe 135 will quickly exchange temperatures, thereby rapidly cooling the air; And under the high-pressure discharge of the lower pressing plate 147, a part of the cold air will be quickly discharged by the jet strip 134. The discharged gas will accumulate on the outer surface of the filter plate 121. Using the inclined surface of the filter plate 121 and under the impact of the jet strip 134, the impurity particles on the surface are washed down, and the excess cold air will initially cool the hot exhaust gas inside the exhaust gas treatment box 12, reducing the temperature of the hot exhaust gas; After the exhaust gas is purified, cooperate with the output end of the hydraulic pump a2 to retract, and make the high-efficiency activated carbon inside the activated carbon cylinder 158 elastically extrude the surface of the baffle plate a4 under the extrusion of gravity, and make the high-efficiency activated carbon inside the activated carbon cylinder 158 in a fluffy state. Cooperate with the one-way valve 146 inside the circulation pipe 143 to close, and pour the clear water inside the cleaning tank 144 into the inside of the exhaust gas treatment box 12 through the circulation water pipe 145, and make the clear water fill half of the space inside the activated carbon purification box 15. As the liquid is continuously filled, the clear water will penetrate into the inside of the activated carbon purification box 15 through the water holes 153. When the water source can completely immerse the high-efficiency activated carbon, cooperate with the motor 156 to rotate the rotating disk 157 and the activated carbon cylinder 158. At this time, the fluffy high-efficiency activated carbon will be turned over, rubbed, and extruded as the activated carbon cylinder 158 rotates, and some of the adhered impurity particles on the outer surface of the high-efficiency activated carbon will be washed down during the rotation; Under the continuous up-and-down extrusion of the lower pressing plate 147, the water source inside the waste gas treatment box 12 will continuously flush inside the waste gas treatment box 12 and the activated carbon purification box 15. With each extraction of the water source, the water source will extract the impurities inside the fluffy high-efficiency activated carbon under the guidance of the water source. After the water source is extracted, the motor 156 is used to rotate the rotating disk 157 at a high speed to discharge the residual water source inside the high-efficiency activated carbon, and then the waste water reflux device 112 extracts and filters the residual sewage inside the air duct 111, and the filtered water source is re-introduced into the inside of the cleaning tank 144 through the circulating water pipe 145 for secondary utilization.
