[0003] The existing waste gas mixed treatment device adopts the process of collecting waste gas, then mixing and treating the collected waste gas, filtering or purifying the harmful substances contained in the waste gas, and then discharging it.

These liquids remain in the pipeline without treatment, which will cause the reduction of the waste gas purification effect over time.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] When the existing waste gas mixing treatment device removes VOCs in the waste gas by the condensation method, by reducing the temperature of the waste gas, the VOCs are condensed into a liquid state, thereby realizing the separation from the waste gas. These liquids remain in the pipeline without treatment, which will cause the consequence of reducing the waste gas purification effect over time.

[0021] In view of this, the present utility model provides an exhaust gas mixing treatment device. Through the cooperation among the circulating condensing pipe, the cylinder and the scraper, when the exhaust gas enters the inside of the condensing box, by injecting cold water into the water inlet pipe, the cold water circulates in the circulating condensing pipe, which can reduce the temperature inside the condensing box, thereby reducing the temperature of the exhaust gas, condensing the harmful substances in the exhaust gas into liquid, and thus realizing the separation from the exhaust gas. For the condensed liquid, by pulling the plugboard, and then starting the cylinder, the cylinder drives the scraper, and the scraper can push the liquid at the bottom of the inner wall of the condensing box into the water collecting tank, and then it is discharged through the drain pipe.

[0022] Through the personnel in this field, the components in this case are connected in sequence. For the specific connection and operation sequence, the following working principle should be referred to. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] Example 1: As Figures 1-4 can be seen, an exhaust gas mixing treatment device includes a ventilation pipe 1. A plurality of air inlets 3 are opened at the top of the ventilation pipe 1. One end of the ventilation pipe 1 is communicated with a dust removal box 5. The other end of the dust removal box 5 is communicated with a condensing box 8. The bottom of the condensing box 8 is communicated with a water collecting tank 20. A plugboard 18 is inserted into the inner wall of the water collecting tank 20. The plugboard 18 extends to the front of the water collecting tank 20. By pulling out the plugboard 18, the liquid condensed under the action of the scraper 17 can be collected into the water collecting tank 20. The bottom of the water collecting tank 20 is communicated with a drain pipe 19. A purification device is arranged inside the condensing box 8. The purification device includes a mounting rod 6, a fan 7, a water inlet pipe 9, a circulating condensing pipe 10, a cylinder 16 and a scraper 17. The mounting rod 6 is fixedly connected to the inner wall of the condensing box 8. Two fans 7 are installed on one side of the mounting rod 6. The exhaust gas flows into the adsorption box 12 under the action of the two fans 7. A circulating condensing pipe 10 is arranged on the side of the fan 7 away from the mounting rod 6. One end of the circulating condensing pipe 10 is communicated with the water inlet pipe 9. The top of the water inlet pipe 9 penetrates through the top of the condensing box 8. The other end of the circulating condensing pipe 10 penetrates through the top of the condensing box 8. A cylinder 16 is arranged below the circulating condensing pipe 10. The cylinder 16 is fixedly connected to the inner wall of the condensing box 8. The output end of the cylinder 16 is fixedly connected to the scraper 17;

[0024] In the specific implementation process, it is particularly pointed out that when the exhaust gas enters the inside of the condensing box 8, by injecting cold water into the water inlet pipe 9, the cold water circulates in the circulating condensing pipe 10, which can reduce the temperature inside the condensing box 8, thereby reducing the temperature of the exhaust gas, condensing the harmful substances in the exhaust gas into liquid, and thus realizing the separation from the exhaust gas. For the condensed liquid, by pulling the plugboard 18, and then starting the cylinder 16, the cylinder 16 drives the scraper 17, and the scraper 17 can push the liquid at the bottom of the inner wall of the condensing box 8 into the water collecting tank 20, and then it is discharged through the drain pipe 19;

[0025] Furthermore, a wind tube 2 is installed on the inner wall side of the ventilation pipe 1 away from the fan 7. The inner wall of the ventilation pipe 1 is rotatably connected to a baffle 23 through a pin shaft. One side of the outer wall of the baffle 23 abuts against a stopper 24, and the outer wall of the stopper 24 is fixedly connected to the inner wall of the ventilation pipe 1. The other side of the outer wall of the baffle 23 abuts against a torsion spring 4, and the outer wall of the torsion spring 4 is fixedly connected to the inner wall of the ventilation pipe 1;

[0026] In the specific implementation process, it is particularly worth noting that when the waste gas is discharged into the interior of the ventilation pipe 1 through a plurality of air inlets 3, and then the wind tube 2 is started, the waste gas advances in the direction of the baffle 23 under the action of the wind tube 2. The waste gas squeezes the baffle 23, and the baffle 23 squeezes the torsion spring 4. The baffle 23 will rotate under the action of the torsion spring 4, and the waste gas passes through the opening generated by the rotation of the baffle 23 and flows into the interior of the dust removal box 5. Under the action of the stopper 24, the waste gas that has passed through the baffle 23 will not flow back, playing a role in preventing backflow;

[0027] Furthermore, two clamping blocks 22 are fixedly connected to the inner wall of the dust removal box 5. A dust removal filter bag 21 is inserted between the two clamping blocks 22 that are close to each other. The dust removal filter bag 21 can filter the particles in the waste gas. The front surface of the dust removal box 5 is rotatably connected to a cover body 25 through a pin shaft;

[0028] In the specific implementation process, it is particularly worth noting that the waste gas passes through the baffle 23 under the action of the wind tube 2, and then the waste gas enters the interior of the dust removal box 5. The waste gas can be filtered for the particles in the waste gas through the dust removal filter bag 21. By virtue of the insertion relationship between the dust removal filter bag 21 and the clamping block 22, the cover body 25 can be opened to replace the dust removal filter bag 21;

[0029] Specifically, when using this waste gas mixing treatment device, when the waste gas is discharged into the interior of the ventilation pipe 1 through multiple air inlets 3, the air cylinder 2 is then started. Under the action of the air cylinder 2, the waste gas advances towards the baffle 23. The waste gas squeezes the baffle 23, and the baffle 23 squeezes the torsion spring 4. The baffle 23 will rotate under the action of the torsion spring 4. The waste gas passes through the opening generated by the rotation of the baffle 23 and flows into the interior of the dust removal box 5. Under the action of the stop block 24, the waste gas that has passed through the baffle 23 will not flow back, playing a role in preventing backflow. The waste gas passes through the baffle 23 under the action of the air cylinder 2, and then the waste gas enters the interior of the dust removal box 5. The waste gas passes through the dust removal filter bag 21, and the particles in the waste gas can be filtered. Due to the plug-in connection between the dust removal filter bag 21 and the clamping block 22, the cover 25 can be opened to replace the dust removal filter bag 21. When the waste gas enters the interior of the condensation box 8, by injecting cold water into the water inlet pipe 9, the cold water circulates in the circulating condensation pipe 10, which can reduce the temperature inside the condensation box 8, thereby reducing the temperature of the waste gas, causing the harmful substances in the waste gas to condense into a liquid, thus realizing the separation from the waste gas. The condensed liquid is pushed into the water collection box 20 by pulling the insertion plate 18 and then starting the air cylinder 16. The air cylinder 16 drives the scraper 17, and the scraper 17 can push the liquid at the bottom of the inner wall of the condensation box 8 into the water collection box 20 and then discharge it through the drain pipe 19.

[0030] Embodiment 2: As Figures 1-4 It can be seen that one side of the outer wall of the condensation box 8 is connected to a connecting pipe 11. The other end of the connecting pipe 11 is provided with an electric valve 15. The other end of the electric valve 15 is connected to an adsorption box 12. The model of the electric valve 15 is not specifically limited here;

[0031] In the specific implementation process, it is particularly noted that after the waste gas is subjected to condensation treatment, the electric valve 15 is opened, and the waste gas flows into the interior of the adsorption box 12 under the action of the fan 7;

[0032] Furthermore, an activated carbon adsorption layer 14 is fixedly connected to the inner wall of the adsorption box 12, and an exhaust pipe 13 is connected to the top of the adsorption box 12;

[0033] In the specific implementation process, it is particularly noted that after the waste gas has been subjected to filtration and condensation treatment, most of the impurities have been removed. Then the waste gas flows into the interior of the adsorption box 12 and passes through the activated carbon adsorption layer 14 to adsorb the remaining impurities in the waste gas, and thus the gas meeting the emission standards can be obtained;

[0034] Specifically, on the basis of the above-mentioned first embodiment, after the waste gas is condensed, the electric valve 15 is opened, and the waste gas flows into the adsorption box 12 under the action of the fan 7. After passing through the filtration and condensation treatment, most of the impurities in the waste gas have been removed. Then the waste gas flows into the adsorption box 12 and passes through the activated carbon adsorption layer 14 to adsorb the remaining impurities in the waste gas, and the gas meeting the emission standards can be obtained.
