Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas condensation, in particular to a toluene reduction extraction machine tail gas condensation device. Background Art

[0002] Toluene reduction extractor is a kind of industrial equipment, which is a machine used to handle and process toluene in industrial production.

[0003] During the use of the toluene reduction extractor, the material containing toluene needs to be placed inside the toluene reduction extractor, and then the toluene reduction extractor is started. At this time, as the toluene reduction extractor is started, toluene is emitted from the material. When toluene is emitted, the emitted exhaust gas needs to be treated to achieve environmental protection.

[0004] After long-term use and observation of the existing toluene reduction extraction machine, it was found that after toluene was processed inside the toluene reduction extraction machine, the exhaust gas directly discharged was too hot. After these exhaust gases were discharged and condensed by the condensation system of the toluene reduction extraction machine, there was still a situation where the exhaust gas was not completely condensed. If it was discharged directly, it would cause waste of toluene and pollution to the environment.

[0005] To this end, the utility model provides a toluene reduction extraction machine tail gas condensation device. Utility Model Content

Through the above structure, the ring and the support rods can cooperate with the Jisang water pipe to be fixed in a specified position, thereby reducing the shaking of the water pipe as the water pump is started, which may cause it to fall off.

[0009] Preferably, the top of the processing barrel is connected to a second air outlet pipe; the end of the second air outlet pipe is connected to an air storage bag. Through the above structure, the excess gas processed inside the processing barrel can be uniformly collected and processed, reducing the discharge of waste gas into the air and the occurrence of environmental pollution caused by it.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4As shown, a toluene reduction extraction machine tail gas condensation device described in an embodiment of the utility model comprises an extraction machine body 1; the side wall of the extraction machine body 1 is connected to a first air outlet pipe 12; the end of the first air outlet pipe 12 is connected to a treatment barrel 13; the inner side wall of the treatment barrel 13 is fixedly connected to a condensation pipe 17; the condensation pipe 17 is arranged around the inner side wall of the treatment barrel 13; the side wall of the treatment barrel 13 is fixedly connected to a support plate 14; the top of the support plate 14 is fixedly connected to a water tank 15; the side wall of the water tank 15 is connected to A water pipe 16 is connected; the end of the water pipe 16 extends to the interior of the processing barrel 13. When working, the extractor body 1 is started to perform preliminary processing on toluene. At this time, the tail gas generated by the processing of toluene will enter the interior of the processing barrel 13 through the first outlet pipe 12. At this time, the condenser 17 inside the processing barrel 13 is started. With the start of the condenser 17, the temperature inside the processing barrel 13 will drop rapidly. At this time, the tail gas inside the processing barrel 13 will also contact with the cold air and then be condensed. At the same time, through the inner part of the water tank 15 The cooling liquid is filled in the water tank 15, and the water pump inside the support plate 14 is started synchronously. As the water pump is started, the cooling liquid inside the water tank 15 will fill the inside of the water pipe 16. At this time, the cooling liquid continues to flow along the contour of the water pipe 16 until it flows to the end of the water pipe 16. At this time, the cooling liquid will be sprayed into the inside of the treatment barrel 13 synchronously with the end of the water pipe 16. At this time, as the cooling liquid is sprayed, the cooling liquid will contact the surface of the condenser tube 17. At this time, the contact between the refrigerated condenser tube 17 and the cooling liquid will make the surface temperature of the condenser tube 17 lower. Through the above structure, the condenser tube 17 and the cooling liquid can work together to quickly reduce the temperature inside the treatment barrel 13. At the same time, the exhaust gas generated by the internal operation of the extractor body 1 can be introduced into the interior of the treatment barrel 13 through the first exhaust pipe 12, thereby achieving the purpose of condensing the exhaust gas generated by the operation of the extractor body 1, reducing the pollution to the environment caused by the exhaust gas being directly discharged into the air. At the same time, by treating the exhaust gas by the condensation method, the heat contained in the exhaust gas can be recovered and reused, further increasing the utilization rate of resources.

[0024] like Figure 1 and Figure 2As shown, a collar 2 is fixedly connected to the middle of the water pipe 16; two support rods 21 are fixedly connected to the side walls of the collar 2; the two support rods 21 are symmetrically arranged, and the ends are fixedly connected to the side walls of the processing barrel 13. During operation, the cooling liquid is continuously sprayed to the inside of the processing barrel 13 through the water pipe 16, so that the surface of the condenser 17 can be continuously in contact with the cooling liquid, so that the inside of the processing barrel 13 is always in a low temperature state. As time goes by, the water pipe 16 will shake to a certain extent as the water pump is continuously started. At this time, as the shaking continues, the water pipe 16 will fall off over time. At this time, the collar 2 is installed in the middle of the water pipe 16, and then the collar 2 and the side walls of the processing barrel 13 are connected together through two support rods 21, so that the water pipe 16 can be supported. Through the above structure, the collar 2 and the support rods 21 can cooperate with the water pipe 16 to be fixed at a specified position, thereby reducing the shaking of the water pipe 16 as the water pump is started, thereby reducing the situation where the water pipe 16 falls off.

[0025] like Figure 1 and Figure 2 As shown, the top of the processing barrel 13 is connected to a second air outlet pipe 3; the end of the second air outlet pipe 3 is connected to an air storage bag 31. During operation, after the exhaust gas is condensed inside the processing barrel 13, the second air outlet pipe 3 can be connected to a designated position, i.e., the top of the processing barrel 13. At this time, with the installation of the second air outlet pipe 3, the air storage bag 31 is also in a designated position with the installation of the second air outlet pipe 3. At this time, the gas inside the processing barrel 13 will enter the interior of the air storage bag 31 through the second air outlet pipe 3. At this time, with the change in the size of the air storage bag 31, the amount of gas stored in the air storage bag 31 can be directly observed. When the gas inside the processing barrel 13 enters the interior of the air storage bag 31, the second air outlet pipe 3 can be pulled out. Through the above structure, the excess gas that has been processed inside the processing barrel 13 can be uniformly collected and processed, reducing the discharge of waste gas into the air, causing environmental pollution.

[0026] like Figure 2 As shown, the inner wall of the processing barrel 13 is fixed with a plurality of fixing parts 4; the plurality of fixing parts 4 are equidistantly distributed on the inner wall of the processing barrel 13, and the condenser 17 is fixed inside the plurality of fixing parts 4. When working, in order to cool down the inside of the processing barrel 13, the condenser 17 needs to be placed inside the processing barrel 13. At this time, a plurality of fixing parts 4 are installed inside the processing barrel 13, and at the same time, the condenser 17 is inserted into the inside of the fixing part 4 to fix the condenser 17. Through the above structure, the condenser 17 can be fixed, which reduces the condenser 17 working inside the processing barrel 13 for a long time, and reduces the possibility of the condenser 17 falling off and causing damage to the condenser 17.

[0027] like Figure 2 and Figure 3 As shown, a plurality of fins 5 are fixedly connected to the middle of the condenser tube 17; the plurality of fins 5 are equidistantly distributed on the surface of the condenser tube 17 and are arranged opposite to each other. When working, by installing a plurality of fins 5 in the middle of the condenser tube 17 and starting the fins 5 at the same time, the operation of the plurality of fins 5 can further reduce the temperature of the surface of the condenser tube 17, thereby making the contact temperature of the exhaust gas entering the interior of the treatment barrel 13 lower. Through the above structure, the exhaust gas can be condensed faster.

[0028] like Figure 3 As shown, a filter plate 6 is fixedly connected to the top of the processing barrel 13; the filter plate 6 is located at the connection point between the first exhaust pipe 12 and the processing barrel 13. During operation, when the exhaust gas enters the interior of the processing barrel 13 from the extractor body 1, the exhaust gas will first contact the filter plate 6. At this time, the exhaust gas in contact with the filter plate 6 will perform preliminary filtration on the exhaust gas entering the interior of the processing barrel 13, thereby reducing the exhaust gas entering the interior of the processing barrel 13, carrying more impurities and dust. Through the above structure, the blockage caused by excessive accumulation of impurities and dust in the processing barrel 13 can be reduced.

[0029] like Figure 2 As shown, the fixing member 4 and the fin 5 are staggered. With the above structure, the situation where the fixing member 4 blocks the fin 5 and thus affects the operation of the fin 5 can be reduced.

[0030] During operation, the extractor body 1 is started to perform preliminary processing on toluene. At this time, the exhaust gas generated by the processing of toluene will enter the interior of the processing barrel 13 through the first exhaust pipe 12. At this time, the condenser 17 inside the processing barrel 13 is started. With the start of the condenser 17, the temperature inside the processing barrel 13 will drop rapidly. At this time, the exhaust gas inside the processing barrel 13 will also come into contact with the cold air and then be condensed. At the same time, by filling the inside of the water tank 15 with coolant, the water pump inside the support plate 14 is started synchronously. With the start of the water pump, the coolant inside the water tank 15 will be filled into the inside of the water pipe 16. At this time, the coolant continues to flow along the contour of the water pipe 16 until it flows to the end of the water pipe 16. At this time, the coolant will be synchronously with the water The end of the tube 16 is sprayed into the interior of the treatment barrel 13. At this time, as the coolant is sprayed, the coolant will contact the surface of the condenser tube 17. At this time, the contact between the refrigerated condenser tube 17 and the coolant will make the surface temperature of the condenser tube 17 lower. Continuously spraying the coolant into the interior of the treatment barrel 13 through the water pipe 16 can make the surface of the condenser tube 17 constantly contact with the coolant, so that the interior of the treatment barrel 13 is always in a low temperature state. As time goes by, the water pipe 16 will shake to a certain extent as the water pump is continuously started. At this time, as the shaking continues, the water pipe 16 will fall off over time. At this time, a ring 2 is installed in the middle of the water pipe 16, and then the ring 2 and the treatment barrel 13 are connected through two support rods 21. The side walls are connected together, so that the water pipe 16 can be supported. When the exhaust gas is condensed inside the treatment barrel 13, the second air outlet pipe 3 can be connected to the specified position, that is, the top of the treatment barrel 13. At this time, with the installation of the second air outlet pipe 3, the air storage bag 31 is also in the specified position with the installation of the second air outlet pipe 3. At this time, the gas inside the treatment barrel 13 will enter the interior of the air storage bag 31 through the second air outlet pipe 3. At this time, as the size of the air storage bag 31 changes, the amount of gas stored in the air storage bag 31 can be directly observed. When the gas inside the treatment barrel 13 enters the interior of the air storage bag 31, the second air outlet pipe 3 can be pulled out to achieve cooling of the inside of the treatment barrel 13. It is necessary to place the condenser 17 at the treatment barrel 13. The interior of the treatment barrel 13 is then fixed by installing multiple fixings 4 inside the treatment barrel 13, and at the same time, the condenser 17 is inserted into the fixings 4 to fix the condenser 17. Multiple fins 5 are installed in the middle of the condenser 17, and the fins 5 are started at the same time. The operation of the multiple fins 5 can further reduce the temperature of the surface of the condenser 17, thereby making the exhaust gas entering the treatment barrel 13 contact with a lower temperature. When the exhaust gas enters the interior of the treatment barrel 13 from the extractor body 1, the exhaust gas will first contact the filter plate 6. At this time, the exhaust gas in contact with the filter plate 6 will perform preliminary filtration on the exhaust gas entering the treatment barrel 13, thereby reducing the exhaust gas entering the treatment barrel 13 and carrying more impurities and dust.
