Description

Technical Field

[0001] The utility model relates to the scope of a waste gas treatment device, in particular to a waste gas treatment device for a glue coating process. Background Art

[0002] Gluing process is widely used in modern industrial production, but it is also accompanied by the emission of glue waste gas. Gluing waste gas contains a large amount of organic solvents, volatile organic compounds and other harmful substances, which will have serious impacts on the environment and human health. Therefore, effective treatment of glue waste gas has become an urgent need.

[0003] The traditional process of treating waste gas from gluing is to first cool the high-temperature waste gas to below the dew point through a condenser tube device, so that the water vapor in the waste gas condenses into liquid water, reducing the evaporation loss during the water washing process. The condensed waste gas is then washed with water, which is the process of exchanging waste gas with high-pressure water mist spray. During the water washing process, the particles in the waste gas collide and collide with the water mist, and the particles are moistened by the water mist and attached to the surface of the water droplets. In addition, the solubility and surface tension of water also help to dissolve the harmful gas components adsorbed in the waste gas into the water.

[0004] However, it is difficult for traditional condensing tubes to fully contact and cool down the high-temperature exhaust gas during condensation, resulting in a certain room for improvement in the condensation effect. In addition, the exhaust gas after condensation needs to be sprayed in a larger spray tank. Due to the large volume of the spray tank, it takes a long time for the exhaust gas and water mist to fully merge, and the fusion effect needs to be improved. In view of this, we propose a glue coating processing exhaust gas treatment device to solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to provide a waste gas treatment device for gluing processing to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gluing processing waste gas treatment device, comprising an outer shell, one side of the outer shell is fixedly connected to an air pump, the air inlet end of the air pump is fixedly connected to an air inlet pipe, the air outlet end of the air pump is fixedly connected to an air supply pipe, one end of the air supply pipe is fixedly connected to a bubble tube, a plurality of air holes are equidistantly provided on the inner wall of the bubble tube, the other side of the outer shell is fixedly connected to a water pump, the liquid outlet end of the water pump is fixedly connected to a liquid supply pipe, the liquid inlet end of the water pump is fixedly connected to a liquid supply pipe, and the bottom of the liquid supply pipe is fixedly connected to a high-pressure nozzle.

[0007] Preferably, the bottom end of the outer wall of the air pipe and the bottom end of the outer wall of the liquid infusion tube are both provided with a mixing chamber, and the inner walls at both ends of the mixing chamber are respectively connected with the bottom end of the outer wall of the liquid infusion tube and the bottom of the outer wall of the air pipe, a driving motor is fixedly connected to the middle position of the top of the outer shell, and a rotating shaft is fixedly connected to the output end of the driving motor.

[0008] Preferably, a plurality of diversion pipes are fixedly connected to the bottom of the mixing bin at equal distances, and the inner wall of each diversion pipe is connected to the inner wall of the mixing bin.

[0009] Preferably, a stirring paddle is fixedly connected to the outer wall of the rotating shaft, and a water injection pipe is fixedly connected to the top of one side of the outer shell.

[0010] Preferably, a drain pipe is fixedly connected to the bottom end of one side of the outer shell, and an exhaust port is fixedly connected to the top end of the other side of the outer shell.

[0011] Preferably, a switch panel is fixedly connected to one side, and an air pump switch, a water pump switch, and a drive motor switch are provided on one side of the switch panel, and the air pump is electrically connected to an external power supply through the air pump switch, the water pump is electrically connected to the water pump switch, and the drive motor is electrically connected to the external power supply through the drive motor switch.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The exhaust gas enters the mixing chamber through the air pipe, and then the exhaust gas is dispersed inside the mixing chamber through the dense pores on the bubble tube. At the same time, the water pump, the liquid inlet pipe and the liquid inlet pipe will pump the filtered water inside the outer shell to the position of the high-pressure nozzle in the mixing chamber. When the water in the high-pressure nozzle is sprayed out, it will collide with the bubble tube and the glue-coated waste gas flowing out from it in the mixing chamber. When the exhaust gas passes through the bubble tube and the pores on its surface, it is screened into many tiny bubbles due to encountering water. The bubbles and water mist generated by the impact of the high-speed water flow, together with the glue-coated waste gas screened into tiny bubbles, make the exhaust gas and water fill the mixing chamber. Compared with the traditional condensation method, the above method can not only quickly cool down the exhaust gas, but also fully fuse and filter most of the particles in the exhaust gas while cooling it down, and then discharge the exhaust gas in the mixing chamber to the inside of the outer shell through multiple shunt pipes at the bottom of the mixing chamber, and then this part of the exhaust gas will enter the filtered water inside the outer shell to achieve the purpose of cooling and filtering again through fusion with the filtered water, and finally be discharged through the exhaust port for the next step of treatment. The above method not only effectively improves the efficiency and effect of exhaust gas condensation and spraying, but also is smaller in size and saves more space than the traditional spray tank;

[0014] 2. A driving motor is provided on the top of the outer shell, which drives the rotating shaft and the stirring paddle to stir the water inside the outer shell. Sufficient stirring is conducive to the fusion of filtered water and exhaust gas, further improving the use effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-4 As shown, the utility model proposes a waste gas treatment device for glue coating processing, comprising an outer shell 1, an air pump 2 is fixedly connected to one side of the outer shell 1, an air inlet end of the air pump 2 is fixedly connected to an air inlet pipe 3, an air outlet end of the air pump 2 is fixedly connected to an air delivery pipe 4, one end of the air delivery pipe 4 is fixedly connected to a bubble tube 5, a plurality of air holes 6 are equidistantly provided on the inner wall of the bubble tube 5, when the waste gas passes through the bubble tube 5 and the air holes 6 on its surface, it is screened into many small bubbles due to encountering water, a water pump 7 is fixedly connected to the other side of the outer shell 1, a liquid outlet end of the water pump 7 is fixedly connected to a liquid delivery pipe 8, a liquid inlet end of the water pump 7 is fixedly connected to a liquid delivery pipe 9, and a high-pressure nozzle 10 is fixedly connected to the bottom of the liquid delivery pipe 8;

[0022] like Figure 2As shown, the bottom ends of the outer walls of the gas delivery pipe 4 and the liquid delivery pipe 8 are both sleeved with a mixing chamber 11, and a driving motor 12 is fixedly connected to the middle position of the top of the outer shell 1, and the driving motor 12 drives the rotating shaft 13 and the stirring paddle 15 to stir the water inside the outer shell 1. Sufficient stirring is conducive to the fusion of filtered water and exhaust gas, and the output end of the driving motor 12 is fixedly connected to the rotating shaft 13, and the outer wall of the rotating shaft 13 is fixedly connected to the stirring paddle 15. The top end of one side of the outer shell 1 is fixedly connected to a water injection pipe 16, the bottom end of one side of the outer shell 1 is fixedly connected to a drain pipe 17, and the top end of the other side of the outer shell 1 is fixedly connected to an exhaust port 18;

[0024] The working principle of the utility model is as follows: when the device is in use, the air pump 2, the water pump 7 and the driving motor 12 are first connected to an external power supply, and then the waste gas generated by the gluing process is introduced into the interior of the outer shell 1 through the air pump 2 and the air inlet pipe 3, and the waste gas is allowed to enter the interior of the mixing chamber 11 through the air delivery pipe 4, and then the waste gas will be dispersed in the interior of the mixing chamber 11 through the dense pores 6 on the bubble tube 5. At the same time, the water pump 7, the liquid inlet pipe 9 and the liquid delivery pipe 8 will pump the filtered water inside the outer shell 1 to the position of the high-pressure nozzle 10 in the mixing chamber 11.
