[0002] Polyurethane, short for polyurethane, is a high-molecular-weight material with excellent mechanical properties and extremely high plasticity, formed by the condensation reaction of polyols and polyisocyanates. Its synthesis can be traced back to 1937, when hexamethylene diisocyanate and butanediol were used as raw materials to first synthesize linear polyurethane resins. The main classifications of polyurethane include polyether, polyester, polyimide, and polyurea types, which can be used to make polyurethane plastics (mainly foamed plastics), polyurethane fibers (known as spandex in China), polyurethane rubber, and elastomers.

[0003] The existing treatment methods for waste gas generated during polyurethane production are not perfect, and most of them rely on manual treatment, which consumes too much labor costs and the cleaning process is relatively complicated. Therefore, a waste gas treatment device for polyurethane prepolymer is proposed. Utility Model Content

[0016] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] A polyurethane prepolymer waste gas treatment device, such as Figure 1 , Figure 2 , Figure 5 As shown, it includes: The outer casing 1 has a motor 9 installed at its bottom. The motor 9 is electrically connected to the power supply module. An air inlet 11 is located on the lower part of the side wall of the outer casing and is connected to the outer casing 1. An air outlet 20 is located on the upper part of the side wall of the outer casing 1 and is connected to the outer casing 1. Support shaft 17 is installed inside the housing 1. One end of support shaft 17 is connected to the output end of motor 9. Activated carbon filter plates 18 are installed on support shaft 17 from top to bottom. Activated carbon filter plates 18 are quarter-circular in shape.

[0019] In a specific embodiment of this utility model, waste gas can enter the device for treatment through the air inlet 11. Since the gas flows upward, the air outlet 20 is located at the top. When the gas enters the device, the motor 9 drives the support shaft 17 to rotate, thereby causing the activated carbon filter plate 18 to rotate, which increases the gas flow path and prolongs the gas residence time in the device, thus better treating the waste gas. The activated carbon filter plate 18 can also adsorb substances such as carbon dioxide in the waste gas. Finally, the treated gas flows out from the air outlet 20, achieving the effect of treating waste gas.

[0020] To solve the problem of how to treat waste gas within the device, such as Figure 1 , Figure 2 As shown, it includes an atomizing sprayer 19, a water pipe 8, and a water pump 7. The atomizing sprayer 19 is installed inside the housing 1 and is electrically connected to the power supply module. The water pipe 8 is installed above the atomizing sprayer 19 and is connected to the atomizing sprayer 19. The output end of the water pump 7 is connected to the water pipe 8.

[0021] In a specific embodiment of this utility model, when the water pump 7 is turned on, water and reaction liquid can be simultaneously pumped into the water pipe 8, and then atomized into water mist by the atomizing sprayer 19, which can better react with the waste gas to treat the waste gas, thus achieving the effect of waste gas treatment in the device.

[0022] To solve the problem of how to add reactants and water, such as Figure 1 , Figure 2 As shown, it includes: Water pipe 24 is installed on the side wall of the outer casing 1 and is connected to the outer casing 1. Water pipe 24 is also connected to the input end of the water pump 7. Feeding box 5 is installed above water pipe 24 and is connected to water pipe 24. Cover 6 is detachably installed on the top of feeding box 5. Electric control valve 12 is installed on feeding box 5 and is electrically connected to power supply module.

[0023] In a specific embodiment of this utility model, the cover 6 can be opened to add clean water into the feeding tank 5, and then the electric control valve 12 can be opened to allow the clean water to flow to the bottom of the outer shell 1. When a certain amount is reached, the electric control valve 12 can be closed, and then the reaction slurry can be added into the feeding tank 5. Finally, the cover 6 of the device can be closed. When the water pump 7 is started, the electric control valve 12 can be opened at the same time, so that the clean water and the reaction slurry are simultaneously pumped into the water pipe 8, achieving the effect of adding reactants and clean water.

[0024] To address how to handle the water-insoluble substances produced by the reaction, such as... Figure 2 , Figure 4 , Figure 6As shown, it includes a filter plate 21, a push plate 15, and a discharge trough 16. The filter plate 21 is installed inside the outer casing 1, the push plate 15 is installed on the support shaft 17, the push plate 15 is in contact with the top of the filter plate 21, and the discharge trough 16 is opened on the upper part of the outer casing 1.

[0025] In a specific embodiment of this utility model, when a water-insoluble reactant falls to the top of the filter plate 21, in order to prevent it from clogging the filter plate 21, the push plate 15 will also rotate with the rotation of the support shaft 17, pushing the water-insoluble reactant to the discharge trough 16, thus achieving the effect of processing water-insoluble substances.

[0026] To solve the problem of how to handle substances that are poorly soluble in water, such as Figure 1 , Figure 6 As shown, it includes a discharge port 22, a piston 23, and a waste treatment box 4. The waste treatment box 4 is installed on the side wall of the outer shell 1. The waste treatment box 4 is connected to the outer shell 1 through a discharge channel 16. The discharge port 22 is opened on the waste treatment box 4. The piston 23 is detachably installed on the discharge port 22. The interior of the waste treatment box 4 is designed with a slope.

[0027] In a specific embodiment of this utility model, when a substance that is difficult to dissolve in water is pushed from the discharge trough 16 into the waste treatment box 4, because the interior of the waste treatment box 4 is designed with a slope, the waste will slide to the discharge port, open the piston 23, and allow the waste to flow out for processing, thus achieving the effect of processing waste.

[0028] To address the question of how to treat wastewater after treating exhaust gas, such as... Figure 3 As shown, it includes a threaded groove 13, a threaded block 14, and a drain outlet 10. The drain outlet 10 is located at the bottom of the outer casing 1, the threaded groove 13 is located on the inner wall of the drain outlet 10, and the threaded block 14 is threadedly connected to the threaded groove 13.

[0029] In a specific embodiment of this utility model, after the exhaust gas is treated, the wastewater produced will fall through the filter plate 21 of the device to the bottom of the inner wall of the outer shell 1, and then by rotating the threaded block 14, the wastewater will flow out from the drain outlet 10, thus achieving the effect of drainage.

[0030] To solve the problem of how to operate and support the device, such as Figure 1-6 As shown, it includes a control panel 2 and a support column 3. The control panel 2 is installed on the side wall of the outer shell 1. The support column 3 is fixed to the bottom of the outer shell 1, the waste disposal box 4, and the water pump 7. The control module is installed inside the control panel 2. The control module is electrically connected to the power supply module and to the water pump 7, the motor 9, the electric control valve 12, and the atomizing sprayer 19.

[0031] In a specific embodiment of this utility model, the operation of the device can be operated by operating the control panel 2, and the support column 3 can support the device.

[0032] Working Principle: Due to the electrical connection between the control module and the water pump 7, motor 9, electric control valve 12, and atomizing sprayer 19, first open the cover 6 and add clean water to the feeding tank 5. Then, open the electric control valve 12 via the control panel 2, allowing clean water to flow into the bottom inner side of the outer casing 1. When the clean water reaches a certain amount, close the electric control valve 12. Next, add the reaction slurry to the feeding tank 5 and close the cover 6. While venting the exhaust gas, simultaneously open the water pump 7, motor 9, electric control valve 12, and atomizing sprayer 19 via the control panel 2. Gas enters through the inlet 11. The motor 9 drives the support shaft 17 to rotate, causing the push plate 15 and activated carbon filter plate 18 to rotate. The gas undergoes preliminary filtration through the filter plate 21 and flows upwards. Due to the rotation of the activated carbon filter plate 18, the gas flow path increases, allowing the gas to stay in the device for a longer period, resulting in a more complete reaction. Simultaneously, the water pump 7 pumps clean water and the reaction slurry... The slurry is pumped to water pipe 8 and then atomized and sprayed out by atomizing sprayer 19, allowing the atomized reactants to better contact and react with the waste gas. The treated waste gas is discharged from outlet 20. The water-insoluble substances generated by the reaction fall on the filter plate 21 inside the device. To prevent them from clogging the filter plate 21, motor 8 also drives push plate 15 to push the water-insoluble substances into waste treatment box 4. Because the interior of waste treatment box 4 is designed with a slope, it flows better to outlet 22 for easy processing. The mist water that does not react with the waste gas inside the device falls to the bottom of the inner side of the outer shell 1 through filter plate 21 and is then pumped away by water pump 7 through water pipe 24 for reuse and to save resources. When the waste gas is completely treated, the device is turned off by operating control panel 2 and the drain outlet 10 is opened by rotating threaded block 14 to discharge the wastewater generated during the treatment, achieving the effect of treating polyurethane prepolymer waste gas.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
