It improves the application performance of amino paint, giving the paint good fluidity and spreadability, making it easier to apply. It also helps to adjust the drying speed and gloss of the paint. Volatile gases are generated during the production of amino paint thinner, which need to be treated.

[0003] For example, Chinese patent CN220817766U discloses a volatile organic gas treatment device, which includes a shell with connecting pipes at both ends, a treatment space inside the shell, and a combustion device inside the treatment space; wherein, the combustion device includes a wind duct, a tungsten rod is arranged in the middle of the wind duct, and a combustion space is arranged between the tungsten rod and the wind duct; one end of the tungsten rod is connected to a heating wire.

[0004] While the aforementioned patents have solved the problem of traditional catalytic combustion requiring catalysts through combustion, for volatile gases produced in the production of amino paint thinners, if they contain complex organic compounds, strict control of temperature and combustion conditions is required during the combustion process to ensure complete combustion, which increases the complexity of the operation.

Therefore, this invention proposes an environmentally friendly treatment device for volatile gases in the production process of amino paint thinner.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly treatment device for volatile gases during the production of amino paint thinner, comprising a base, a treatment mechanism on the top of the base, the treatment mechanism including a condenser, a treatment box and an adsorption plate, the bottom of the condenser being fixedly connected to the base, the outlet of the condenser being fixedly connected to a gas-liquid separator, the bottom of the gas-liquid separator being fixedly connected to the base, one end of the gas-liquid separator being fixedly connected to a connecting pipe, one end of the connecting pipe being fixedly connected to the treatment box, the bottom of the treatment box being fixedly connected to the base, a support frame being slidably connected inside the treatment box, one side of the support frame engaging with the adsorption plate, a sealing strip overlapping the top of the support frame, a sealing cover engaging with the bottom of the sealing strip, the bottom of the sealing cover engaging with the treatment box, and a heating plate being inserted through the inside of the sealing cover, the bottom of the heating plate engaging with the inner wall of the treatment box.

Detailed Implementation

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: An environmentally friendly treatment device for volatile gases generated during the production of amino paint thinner includes a base 6. A treatment mechanism is installed on top of the base 6, comprising a condenser 8, a treatment chamber 9, and an adsorption plate 12. The bottom of the condenser 8 is fixedly connected to the base 6, and a gas-liquid separator 21 is fixedly connected to the outlet of the condenser 8. The bottom of the gas-liquid separator 21 is fixedly connected to the base 6, and a connecting pipe 18 is fixedly connected to one end of the gas-liquid separator 21. One end of the connecting pipe 18 is fixedly connected to the treatment chamber 9, and the bottom of the treatment chamber 9 is fixedly connected to the base 6. A support frame 19 is slidably connected inside the treatment chamber 9, and one side of the support frame 19 is connected to the adsorption plate 12. The auxiliary plate 12 is engaged, the top of the support frame 19 is connected to the sealing strip 11, the bottom of the sealing strip 11 is engaged with the sealing cover 10, the bottom of the sealing cover 10 is engaged with the processing box 9, and a heating plate 16 is inserted through the inside of the sealing cover 10. The bottom of the heating plate 16 is engaged with the inner wall of the processing box 9. The bottom of the processing box 9 is fixedly connected to the motor 15, the top of the output shaft of the motor 15 is fixedly connected to the lead screw 13, the top of the lead screw 13 is rotatably connected to the sealing cover 10, and the lead screw 13 is connected to the connector 14 by thread. One side of the connector 14 is fixedly connected to the support frame 19, and the support frame 19 and the sealing cover 10 are slidably connected.

[0024] The base 6 can be used to support and reinforce the bottom of the condenser 8. The gas discharged from the condenser 8 can be separated into gas and liquid by the gas-liquid separator 21. The separated gas can be sent into the treatment box 9 through the connecting pipe 18. The heating temperature of the heating plate 16 can be controlled by an external controller. The gas can be heated when it passes through the small through holes on the heating plate 16, thereby realizing the temperature regulation of the gas. The adsorption plate 12 can adsorb and remove the residual harmful substances in the gas, thus completing the gas treatment. The motor 15 can drive the lead screw 13 to rotate. The lead screw 13 is connected to the connecting piece 14 by a thread, which can drive the connecting piece 14 to move along the lead screw 13. Through the two symmetrically arranged lead screws 13 and the motor 15, the support frame 19 can be driven to rise and fall smoothly inside the treatment box 9, thereby removing the support frame 19 from the treatment box 9, which is convenient for the disassembly and replacement of the adsorption plate 12. The sealing strip 11 can seal and protect the top of the sealing cover 10, reducing gas leakage when the treatment box 9 is in use.

[0025] Example 2: Figures 1-3 As shown, a guide pipe 17 is fixedly connected to one side of the treatment box 9, an axial flow fan 5 is fixedly connected to one end of the guide pipe 17, a diversion pipe 4 is fixedly connected to one side of the axial flow fan 5, a detection box 3 is fixedly connected to one end of the diversion pipe 4, the bottom of the detection box 3 is fixedly connected to the base 6, a gas sensor 2 is fixedly connected to the top of the detection box 3, the bottom of the gas sensor 2 penetrates the top side wall of the detection box 3, and a discharge pipe 1 is connected to one side of the detection box 3 through a valve. A flow meter 7 is fixedly connected to the inlet of the condenser 8, and an exhaust gas pipe 20 is fixedly connected to one end of the flow meter 7.

[0026] The guide pipe 17 guides the gas discharged from the treatment box 9. The axial flow fan 5 accelerates the flow of gas between the guide pipe 17 and the diversion pipe 4. The treated gas is sent into the detection box 3 through the diversion pipe 4. The gas sensor 2 detects the composition and content of the gas. By comparing the detection results with the predetermined values, it can be determined whether the current gas treatment is qualified. The qualified gas is discharged through the discharge pipe 1. The flow meter 7 detects the flow rate of the gas flowing into the condenser 8, which facilitates the adjustment of the gas flow rate using external control equipment.

[0027] The operating method and working principle of this device are as follows: First, the volatile gases generated during the production of amino paint thinner are sent into the waste gas pipe 20. The flow rate of the gas is detected by the flow meter 7. The detected gas enters the condenser 8, where it exchanges heat with a cooling medium such as cold water, cold air, or refrigerant, and the temperature gradually decreases. When the temperature drops to the dew point temperature of the corresponding substances, substances such as alcohols, esters, ketones, and aromatics will condense into liquids one after another. These liquids are separated by the gas-liquid separator 21 and then enter the treatment tank 9 through the connecting pipe 18. After being heated by the heating plate 16, the liquid is adsorbed by the activated carbon on the adsorption plate 12. The treated gas enters the guide pipe 17 and the drainage pipe 4, and then enters the detection box 3 to be detected by the gas sensor 2. After passing the detection, the valve between the discharge pipe 1 and the detection box 3 can be opened to discharge the gas. When it is necessary to replace the adsorption plate 12, the sealing strip 11 can be removed from the top of the sealing cover 10. The motor 15 is started by using an external controller. The top of the two lead screws 13 is equipped with a synchronous belt, which can realize the synchronous rotation of the two lead screws 13. The connecting piece 14 and the support frame 19 move smoothly upward inside the treatment box 9, exposing the support frame 19 and the adsorption plate 12. At this time, the adsorption plate 12 can be removed from the support frame 19 for replacement.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
