Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to a waste gas treatment device for adhesive production. Background Technology

[0002] Adhesives are substances with good bonding properties, which connect objects through surface adhesion and cohesion. The production process of adhesives generates a large amount of waste gas, which, if directly released into the air, will pollute the environment. Therefore, the waste gas generally needs to be treated before being released.

[0003] Chinese utility model patent CN217340789U discloses an environmentally friendly waste gas treatment device for adhesive production, including a frame with a treatment chamber for holding a reaction liquid on the frame. The treatment chamber is connected to an inlet pipe for introducing waste gas and an outlet pipe for discharging gas. The treatment chamber is equipped with an atomizing spray assembly, which includes an atomizing nozzle. The atomizing nozzle is connected to the reaction liquid through an inlet pipe. When treating the waste gas, the waste gas is introduced into the treatment chamber through the inlet pipe, and the reaction liquid is sprayed out from the atomizing nozzle to react with the harmful substances in the waste gas. After the reaction, the reaction liquid falls back into the treatment chamber, and the treated waste gas is discharged out from the outlet pipe.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: During operation, when the exhaust gas flow rate is too high, the reaction liquid sprayed from the atomizing nozzle will be entrained by the high-speed airflow and cannot fall back into the treatment chamber. It will either be directly discharged from the exhaust pipe or reach subsequent treatment steps. Direct discharge will impact the external environment, while reaching subsequent treatment steps may interfere with the normal operation of subsequent processes. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a waste gas treatment device for adhesive production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste gas treatment device for adhesive production, comprising a conveying pipe and a treatment tank for containing treatment liquid, an input pipe vertically arranged on the top of the treatment tank, an air inlet opened at the bottom of one side wall of the treatment tank, one end of the conveying pipe connected to the air inlet and the other end connected to the lower end of the input pipe, a plurality of staggered baffles arranged inside the treatment tank, an air outlet opened on the top of the treatment tank, an air outlet pipe arranged inside the air outlet, an air pump arranged on the air outlet pipe, a rotating shaft vertically rotatably arranged inside the treatment tank, the upper end of the rotating shaft passing through the treatment tank, the conveying pipe placed inside the input pipe and provided with a mounting column, a plurality of fan blades arranged circumferentially at intervals on the mounting column, and a stirring rod arranged on the shaft between two adjacent baffles of the rotating shaft.

[0007] By adopting the above technical solution, a delivery pipe, baffles, an air pump, and a rotating shaft are installed. The air pump draws air from the treatment chamber, creating negative pressure, which forces the waste gas into the treatment chamber through the input pipe and delivery pipe, ensuring full contact with the treatment liquid for treatment. As the waste gas rises in the treatment liquid, it is impeded by several baffles, extending the contact time with the liquid and ensuring treatment effectiveness. Simultaneously, as the waste gas passes through the input pipe, it blows the fan blades, driving the mounting column and rotating shaft to rotate, which in turn rotates several stirring rods to agitate the treatment liquid in the treatment chamber, increasing its fluidity and enhancing the gas-liquid mixing effect, thus improving the waste gas treatment efficiency. The treatment liquid is not carried away by the airflow to the outlet pipe, preventing it from reaching the outside environment and impacting subsequent steps.

[0008] Furthermore, the width of the baffle is the same as the internal width of the processing box, and its length is less than the internal length of the processing box.

[0009] Furthermore, the baffle is arranged at an angle, with one side of the baffle along its length connected to the inner wall of the processing box, and the side of the baffle connected to the inner wall of the processing box along its length being lower than the opposite side.

[0010] By adopting the above technical solution, the baffle is arranged at an angle, and after the exhaust gas comes into contact with the bottom surface of the baffle, it rises from the bottom side of the baffle to the top side.

[0011] Furthermore, a dispersion mesh is horizontally arranged on the upper side of the baffle.

[0012] By adopting the above technical solution and setting up a dispersing screen, the airflow is dispersed by the dispersing screen during its upward process, resulting in better contact with the treatment liquid.

[0013] Furthermore, the processing box is equipped with a dispersion tube, which is connected to the conveying tube. Several exhaust ports are horizontally spaced on the dispersion tube, and an exhaust mesh plate is installed in each exhaust port.

[0014] By adopting the above technical solution, a dispersion pipe, an exhaust port, and an exhaust screen are installed to disperse the waste gas entering the treatment box.

[0015] Furthermore, three blocking mesh plates are vertically spaced on the upper side inside the processing box.

[0016] By adopting the above technical solution and setting up a baffle plate, when the exhaust gas passes through the treatment liquid, some of the treatment liquid will splash up. The baffle plate blocks the splashed treatment liquid, preventing the treatment liquid from splashing into the gas pipe.

[0017] Furthermore, the stirring rod is provided with several stirring bars at horizontal intervals.

[0018] By adopting the above technical solution, several stirring rods are horizontally spaced on the stirring rod to further enhance the gas-liquid mixing effect.

[0019] In summary, this utility model has the following beneficial effects: In this application, a conveying pipe, baffles, an air pump, and a rotating shaft are provided. The air pump draws air from the treatment chamber, creating a negative pressure, allowing the waste gas to enter the treatment chamber sequentially through the input pipe and the conveying pipe, ensuring full contact with the treatment liquid for treatment. As the waste gas rises in the treatment liquid, it is impeded by several baffles, extending the contact time with the treatment liquid and ensuring the treatment effect. Simultaneously, as the waste gas passes through the input pipe, it blows the fan blades, driving the mounting column and rotating shaft to rotate, which in turn drives several stirring rods to stir the treatment liquid in the treatment chamber, increasing the fluidity of the treatment liquid and thus enhancing the gas-liquid mixing effect and improving the waste gas treatment efficiency. The treatment liquid will not be carried away by the airflow to the outlet pipe, preventing the treatment liquid from reaching the outside environment and affecting subsequent steps.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-6 As shown in the embodiment of this application, a waste gas treatment device for adhesive production is disclosed, including a conveying pipe 10, a treatment box 20, an input pipe 21, and a rotating shaft 40. The treatment box 20 is used to contain the treatment liquid. A support frame is provided on the top of the input pipe 21, and the input pipe 21 is vertically mounted on the support frame. An air inlet is opened at the bottom of one side wall of the treatment box 20. One end of the conveying pipe 10 is connected to the air inlet, and the other end is connected to the lower end of the input pipe 21. Several staggered baffles 30 are provided inside the treatment box 20. An air outlet is opened at the top of the treatment box 20, and an air outlet pipe 22 is provided inside the air outlet. An air pump 23 is provided on the air outlet pipe 22. The air pump 23 draws air from the treatment box 20 to form a negative pressure, so that the waste gas enters the treatment box 20 sequentially through the input pipe 21 and the conveying pipe 10, and fully contacts the treatment liquid for treatment. During the process of the waste gas rising in the treatment liquid, it is blocked by several baffles 30, which prolongs the contact time with the treatment liquid and ensures the treatment effect. A vertically rotating shaft 40 is installed inside the treatment chamber 20. The upper end of the shaft 40 passes through the treatment chamber 20 and the conveying pipe 10, and is placed inside the input pipe 21, where a mounting column 41 is installed. Several fan blades 42 are spaced circumferentially on the mounting column 41. Stirring rods 43 are installed on the shaft of the rotating shaft 40 between two adjacent baffles 30. When exhaust gas passes through the input pipe 21, it blows the fan blades 42, driving the mounting column 41 and the rotating shaft 40 to rotate. This, in turn, causes the stirring rods 43 to rotate, stirring the treatment liquid inside the treatment chamber 20, increasing the fluidity of the treatment liquid, thereby enhancing the gas-liquid mixing effect and improving the exhaust gas treatment efficiency. The treatment liquid will not be carried away by the airflow to the outlet pipe 22, preventing it from reaching the outside environment and affecting subsequent steps.

[0029] Specifically, a dispersion pipe 11 is installed inside the treatment box 20, which is connected to the conveying pipe 10. Several exhaust ports 12 are horizontally spaced on the dispersion pipe 11, and exhaust mesh plates 13 are installed inside the exhaust ports 12 to disperse the waste gas entering the treatment box 20. Several stirring rods 44 are horizontally spaced on the stirring rod 43 to further enhance the gas-liquid mixing effect.

[0030] In its configuration, the width of the baffle 30 is the same as the internal width of the treatment box 20, while its length is less than the internal length of the treatment box 20. The baffle 30 is arranged at an angle, with one side of the baffle 30 along its length connected to the inner wall of the treatment box 20, and the side of the baffle 30 connected to the inner wall of the treatment box 20 along its length being lower than the opposite side. Both sides of the baffle 30 along its width are connected to the inner wall of the treatment box 20. After the exhaust gas contacts the bottom surface of the baffle 30, it rises under the guidance of the baffle 30. A dispersion mesh plate 31 is horizontally arranged on the upper side of the baffle 30. One side of the dispersion mesh plate 31 is connected to the baffle 30, and the other three sides are connected to the inner wall of the treatment box 20. During the upward flow of the air, the dispersion mesh plate 31 disperses the airflow, resulting in better contact with the treatment liquid.

[0031] In the specific configuration, three baffle plates 24 are vertically spaced at intervals on the upper side inside the treatment tank 20. When the exhaust gas passes through the treatment liquid, some of the treatment liquid will splash up. The baffle plates 30 block the splashed treatment liquid to prevent it from splashing into the exhaust pipe 22. Both the baffle plates 30 and the baffle plates 24 have through holes corresponding to the rotating shaft 40, and the through holes are rotatably connected to the rotating shaft 40.

[0032] A first through-hole is provided at the bottom of one side wall of the treatment tank 20, and a second through-hole is provided on the lower side of the corresponding baffle 30. The first and second through-holes are connected by a drain pipe, which is equipped with a drain valve. When the treatment solution in the treatment tank 20 needs to be replaced, the drain valve is opened, and the treatment solution flows through the first and second through-holes into the drain pipe and is discharged. Residual treatment solution on the baffle 30 can also be discharged through the second through-hole. A third through-hole is provided on the side wall of the treatment tank 20, and a water pipe is installed in the third through-hole. The water pipe is equipped with a water inlet valve. By opening the water inlet valve, treatment solution can be added into the treatment tank 20 through the water pipe.

[0033] The operating principle of the waste gas treatment device for adhesive production in this embodiment is as follows: The vacuum pump 23 is activated to extract air from the treatment tank 20, creating a negative pressure. This allows the waste gas to sequentially enter the treatment tank 20 through the input pipe 21, delivery pipe 10, dispersion pipe 11, and exhaust screen 13, ensuring full contact with the treatment liquid for processing. As the waste gas rises in the treatment liquid, it is impeded by several baffles 30 and dispersion screens 31, extending the contact time with the treatment liquid and ensuring the treatment effect. When the waste gas passes through the input pipe 21, it actuates the fan blades 42, driving the mounting column 41 and rotating shaft 40 to rotate. This, in turn, drives several stirring rods 43 and stirring bars 44 to rotate, stirring the treatment liquid in the treatment tank 20, increasing its fluidity, thereby enhancing the gas-liquid mixing effect and improving the waste gas treatment efficiency. Finally, the waste gas is discharged from the exhaust pipe 22.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
