Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology, specifically a waste gas treatment device for bamboo and wood furniture coating. Background Technology

[0002] In the coating process of bamboo and wood furniture, exhaust gas treatment is a crucial step in ensuring environmental protection and occupational health. However, most coating exhaust gas treatment equipment currently on the market is designed for coating exhaust gases from metal or industrial parts, and its processes and structures are difficult to fully adapt to the complex characteristics of high concentrations of volatile organic compounds, particulate matter, and special odor substances in the coating exhaust gases from bamboo and wood furniture. This limitation leads to low treatment efficiency, high energy consumption, and difficulty in meeting stringent environmental emission standards in some scenarios.

[0003] For example, Chinese invention patent (publication number: CN114082267B) discloses an integrated equipment for treating volatile organic waste gas from painting and spraying, published on April 15, 2022. This equipment pre-treats the paint spraying waste gas using a venturi dust collector, a cyclone dust collector, and a bag filter, effectively removing fine paint mist particles and thus improving the efficiency and lifespan of the subsequent zeolite adsorption material. However, this equipment is mainly designed for paint spraying waste gas from metal workpieces, and its effectiveness in treating high-concentration volatile organic compounds and complex particulate matter generated during the painting process of bamboo and wood furniture is limited. Furthermore, its overall structure is relatively complex, resulting in high maintenance costs.

[0004] For example, Chinese invention patent (publication number: CN114570196B) discloses a system for treating organic waste gas from metal coating, published on September 27, 2024. This system employs components such as a liquid storage tank, a gas generating mechanism, a catalytic reaction unit, an exhaust pipe, and a circulating pump to achieve efficient treatment of organic waste gas through catalytic reaction. Although this design is easy to maintain, it primarily targets the organic components in metal coating waste gas and lacks sufficient comprehensive treatment capacity for mixed waste gas from bamboo and wood furniture coating processes, thus lacking optimized design tailored to the characteristics of waste gas from bamboo and wood furniture coating.

[0005] The aforementioned problems indicate that existing coating exhaust gas treatment equipment has certain limitations in dealing with exhaust gas from bamboo and wood furniture coating. Therefore, this utility model proposes a device specifically for treating exhaust gas from bamboo and wood furniture coating, to provide a more efficient, energy-saving solution that meets the coating needs of bamboo and wood furniture.

The adsorption purification module includes an activated carbon filter and an exhaust pressure boosting unit. The activated carbon filter is located at the inlet of the adsorption purification module, and the exhaust pressure boosting unit is located at the outlet of the adsorption purification module.

[0008] As a preferred technical solution of this application, the cyclone separation assembly includes a cyclone cylinder and guide vanes. The inner wall of the cyclone cylinder is provided with arc-shaped guide vanes along the axial direction. The outer side of the guide vanes is welded and fixed to the inner wall of the cyclone cylinder, and the inner side of the guide vanes forms a spiral airflow channel. The bottom of the cyclone cylinder is provided with a particle collection chamber, which is sealed to the bottom of the cyclone cylinder by a threaded connection.

[0009] As a preferred technical solution of this application, the electrostatic collection assembly includes a high-voltage electrode plate and a grounding electrode plate. The high-voltage electrode plate and the grounding electrode plate are arranged alternately and fixed on an insulating support. The insulating support is installed on the inner wall of the pretreatment module housing by bolts. The high-voltage electrode plate is connected to an external power source by wires.

[0010] As a preferred technical solution of this application, the honeycomb catalyst carrier of the catalyst bed is made of a ceramic substrate, the surface of the ceramic substrate is coated with a noble metal catalyst layer, the noble metal catalyst layer is attached to the surface of the ceramic substrate by a spraying process, and the honeycomb catalyst carrier is fixed in the catalyst bed by a slot.

[0011] As a preferred technical solution of this application, the heating unit includes a heating wire and a heat insulation layer. The heating wire is wound around the outside of the heat-conducting plate, and the heat insulation layer is wrapped around the outside of the heating wire. The heat-conducting plate is fixed to the outer wall of the catalytic bed by screws.

[0012] As a preferred technical solution of this application, the activated carbon filter element includes a filter element shell and a filling layer. The filter element shell has a cylindrical structure with sealing rings at both ends. The filling layer is composed of porous activated carbon particles, which are fixed inside the filter element shell by a sieve.

[0013] As a preferred technical solution of this application, the exhaust booster unit includes a turbo fan and a motor.

The air inlet of the turbo fan is connected to the inner cavity of the adsorption purification module, and the air outlet of the turbo fan is connected to the exhaust pipe.

[0020] In summary, this utility model solves the problems of low efficiency, high energy consumption, and difficulty in meeting environmental emission standards when treating exhaust gas from bamboo and wood furniture coating by the synergistic effect of a multi-stage treatment structure. At the same time, the overall structural design is reasonable and the maintenance cost is low, which has significant practicality and promotional value. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a waste gas treatment device for bamboo and wood furniture coating, the overall structure of which is as follows: Figure 1 As shown, the system includes an exhaust gas inlet pipe 1, a pretreatment module 2, a catalytic decomposition module 3, and an adsorption purification module 4. The exhaust gas inlet pipe 1 is connected to the input end of the pretreatment module 2 via a flange. The output end of the pretreatment module 2 is connected to the catalytic decomposition module 3 via a pipe, and the output end of the catalytic decomposition module 3 is connected to the adsorption purification module 4 via a pipe. The entire system adopts a multi-stage treatment structure, with exhaust gas being transported step-by-step between modules via pipelines, ensuring that the exhaust gas is fully treated in each module.

[0031] Pretreatment module 2 is the first treatment stage after the exhaust gas enters the equipment. Its internal structure is as follows: Figure 2 As shown, the system includes a cyclone separation assembly 5 and an electrostatic collection assembly 6. The cyclone separation assembly 5 is located at the front end of the pretreatment module 2 and mainly consists of a cyclone cylinder and guide vanes 12. The inner wall of the cyclone cylinder has arc-shaped guide vanes 12 arranged axially. The outer side of the guide vanes 12 is welded and fixed to the inner wall of the cyclone cylinder, forming a spiral airflow channel on the inner side. When exhaust gas enters the cyclone separation assembly 5 from the exhaust gas inlet pipe 1, the guide vanes 12 guide the exhaust gas to form a spiral airflow. Particulate matter in the exhaust gas is thrown to the inner wall of the cyclone cylinder under centrifugal force and finally falls into the particle collection chamber 11. The particle collection chamber 11 is sealed to the bottom of the cyclone cylinder via a threaded connection, facilitating periodic cleaning of the collected particles. The electrostatic collection assembly 6 is located at the rear end of the cyclone separation assembly 5. The electrostatic collection assembly 6 includes a high-voltage electrode plate 13 and a grounding electrode plate 14, which are alternately arranged and fixed to the inner wall of the pretreatment module 2 housing via an insulating bracket. The high-voltage electrode plate 13 is connected to an external power source via a wire. Under the action of the high-voltage electric field, the tiny particulate matter in the exhaust gas is further captured, thereby improving the particulate matter removal efficiency.

[0032] After passing through pretreatment module 2, the exhaust gas enters catalytic decomposition module 3 via pipeline. The structure of catalytic decomposition module 3 is as follows: Figure 3As shown, the system includes a catalytic bed 7 and a heating unit 8. The catalytic bed 7 contains a honeycomb catalyst carrier 15, which is made of a ceramic substrate and coated with a precious metal catalyst layer. The precious metal catalyst layer is attached to the surface of the ceramic substrate by a spraying process, and the honeycomb catalyst carrier 15 is fixed inside the catalytic bed 7 by slots. The heating unit 8 is arranged around the outside of the catalytic bed 7 and includes heating wires and an insulation layer. The heating wires are wound around the outside of a heat-conducting plate, and the insulation layer is wrapped around the outside of the heating wires. The heat-conducting plate is fixed to the outer wall of the catalytic bed 7 by screws. The heating unit 8 transfers heat to the inside of the catalytic bed 7 through the heat-conducting plate, allowing the exhaust gas to react with the precious metal catalyst at a suitable temperature, converting volatile organic compounds into carbon dioxide and water vapor. To ensure the stability of the catalytic decomposition process, a temperature sensor 18 is installed in the connecting pipe between the pretreatment module 2 and the catalytic decomposition module 3. The temperature sensor 18 is fixed to the inner wall of the pipe by a threaded connection, and its signal output terminal is connected to the control circuit of the heating unit 8 for real-time monitoring of the exhaust gas temperature and adjustment of the operating status of the heating unit 8.

[0033] The waste gas treated by the catalytic decomposition module 3 enters the adsorption purification module 4 through a pipeline. The structure of the adsorption purification module 4 is as follows: Figure 4 As shown, the system includes an activated carbon filter element 9 and an exhaust booster unit 10. The activated carbon filter element 9 is located at the inlet of the adsorption purification module 4, and its structure includes a filter element shell and a filling layer. The filter element shell has a cylindrical structure with sealing rings at both ends. The filling layer consists of porous activated carbon particles, which are fixed inside the filter element shell by a screen. After the exhaust gas enters the adsorption purification module 4, residual pollutants are adsorbed by the activated carbon particles, thereby further purifying the exhaust gas. The exhaust booster unit 10 is located at the outlet of the adsorption purification module 4 and includes a turbine fan 16 and a motor. The blades of the turbine fan 16 are fixed to the motor output shaft via a coupling, and the motor is fixedly connected inside the adsorption purification module 4. The air inlet of the turbine fan 16 communicates with the inner cavity of the adsorption purification module 4, and the air outlet is connected to the exhaust pipe. Through boosting, the purified gas is quickly discharged from the equipment, ensuring the smoothness of the exhaust process. The top of the housing of the adsorption purification module 4 is equipped with a pressure balancing valve 17. The pressure balancing valve 17 is installed on the top of the housing by means of a threaded connection. Its valve core is connected to the inner cavity of the housing by a spring. It is used to adjust the pressure inside the adsorption purification module 4 to avoid the adsorption effect being affected by excessively high or low pressure.

[0034] In actual operation, the exhaust gas first enters the pretreatment module 2 through the exhaust gas inlet pipe 1. The cyclone separation component 5 uses the spiral airflow formed by the guide vanes 12 to throw the particulate matter into the particle collection chamber 11. Then, the exhaust gas enters the electrostatic capture component 6, where the electric field generated by the high-voltage electrode plate 13 and the grounding electrode plate 14 further removes the fine particulate matter. The pretreated exhaust gas enters the catalytic decomposition module 3 through a pipeline. At the suitable temperature provided by the heating unit 8, the volatile organic compounds in the exhaust gas react with the precious metal catalyst in the catalytic bed 7, converting them into harmless carbon dioxide and water vapor. The catalytically decomposed exhaust gas enters the adsorption purification module 4, where the activated carbon filter 9 adsorbs the residual pollutants. The turbine fan 16 uses a pressurizing effect to quickly discharge the purified gas from the equipment, completing the entire exhaust gas treatment process.

[0035] This utility model, through the design and arrangement of the above-described structure, achieves efficient treatment of exhaust gas from bamboo and wood furniture coating, meeting the requirements of environmental protection emission standards. Simultaneously, the overall structural design is reasonable, resulting in low maintenance costs. To enable those skilled in the art to more fully understand and implement this utility model, the following supplementary explanation of its implementation principle is provided in conjunction with specific application scenarios.

[0036] In the process of treating exhaust gas from bamboo and wood furniture coating, the exhaust gas generated during the coating operation is first introduced into the pretreatment module 2 through the exhaust gas inlet pipe 1. After the exhaust gas enters the cyclone separator 5, the guide vanes 12 guide the exhaust gas to form a spiral airflow. Due to centrifugal force, particulate matter is thrown to the inner wall of the cyclone cylinder and slides down the inner wall into the particle collection chamber 11. At this time, the removal of particulate matter mainly relies on the design features of the cyclone separator 5, that is, the spiral airflow formed by the guide vanes 12 can effectively enhance the separation efficiency between particulate matter and airflow. The particle collection chamber 11 is sealed to the bottom of the cyclone cylinder by a threaded connection, which facilitates the periodic cleaning of the collected particulate matter and ensures the long-term stable operation of the equipment.

[0037] Subsequently, the exhaust gas enters the electrostatic precipitator 6. The high-voltage electric field formed between the high-voltage electrode plate 13 and the grounded electrode plate 14 exerts an electric force on the tiny particulate matter in the exhaust gas, further capturing it. The high-voltage electrode plate 13 is connected to an external power source via wires, and the generated electric field strength is sufficient to overcome the Brownian motion of the particulate matter, thereby achieving efficient capture. In this step, the design of the electrostatic precipitator 6 not only improves the particulate matter removal efficiency but also provides a relatively clean exhaust gas environment for the subsequent catalytic decomposition process, reducing the risk of catalyst poisoning.

[0038] The pretreated waste gas is transported to the catalytic decomposition module 3 via pipeline. During this process, the temperature sensor 18 monitors the waste gas temperature in real time and transmits the signal to the control circuit of the heating unit 8. The heating unit 8 adjusts the working state of the heating wire according to the signal fed back by the temperature sensor 18 to ensure that the waste gas reaches a suitable reaction temperature when it enters the catalytic bed 7. The honeycomb catalyst carrier 15 inside the catalytic bed 7 is made of ceramic substrate, and the noble metal catalyst layer coated on its surface is attached by a spraying process, exhibiting high catalytic activity and stability. The volatile organic compounds in the waste gas undergo an oxidation reaction under the action of the noble metal catalyst, converting into carbon dioxide and water vapor. The honeycomb structure design increases the contact area between the waste gas and the catalyst, significantly improving the catalytic decomposition efficiency while reducing energy consumption.

[0039] The exhaust gas after catalytic decomposition enters the adsorption purification module 4, where the activated carbon filter element 9 adsorbs residual pollutants. The filling layer of the activated carbon filter element 9 is composed of porous activated carbon particles, which are fixed inside the filter element shell by a sieve. These particles have a large specific surface area and abundant pore structure, which can effectively adsorb trace pollutants in the exhaust gas. The pressure balancing valve 17 in the adsorption purification module 4 is connected to the inner cavity of the shell by a spring, which can dynamically adjust the pressure in the module to avoid a decrease in adsorption efficiency due to excessive pressure or an impact on exhaust smoothness due to excessively low pressure. The turbine fan 16 in the exhaust booster unit 10 is driven by a motor to quickly discharge the purified gas from the equipment, ensuring that the entire exhaust process is efficient and stable.

[0040] In the above steps, the synergistic effect between the modules achieves efficient treatment of exhaust gas from bamboo and wood furniture coating. The staged design of the cyclone separation component 5 and the electrostatic capture component 6 significantly improves the removal efficiency of particulate matter; the cooperation between the catalytic bed 7 and the heating unit 8 ensures the efficient decomposition of volatile organic compounds; and the design of the activated carbon filter element 9 and the exhaust pressure boosting unit 10 further enhances the purification effect and emission efficiency of the exhaust gas. Through this multi-stage treatment structure design, this invention not only meets the requirements of environmental emission standards but also significantly reduces the operating energy consumption and maintenance costs of the equipment.

[0041] In summary, this utility model, through its reasonable structural design and scientific operating principle, solves the problems of low efficiency, high energy consumption, and difficulty in meeting environmental protection requirements in the treatment of exhaust gas from bamboo and wood furniture coating. It has high practicality and promotional value.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
