Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown in the figure, an embodiment of this application discloses a spray booth exhaust gas treatment device, including a spray booth 1. One side of the spray booth 1 is a paint spraying chamber, and the other side of the spray booth 1 is provided with a water curtain filtration mechanism. The water curtain filtration mechanism includes a water curtain plate 2. The side of the water curtain plate 2 away from the paint spraying chamber forms a purification chamber. Multiple baffles 3 are arranged alternately from top to bottom in the purification chamber. The multiple baffles 3 are arranged obliquely downwards. It also includes a water tank assembly 4 that provides water flow to the water curtain plate 2 and the baffles 3. A wastewater tank 5 is provided below the water curtain plate 2 and the baffles 3. It also includes a wastewater filtration system 6 connected between the wastewater tank 5 and the water tank assembly 4. It also includes an air self-circulation system 7. The air inlet of the air self-circulation system 7 is connected to the purification chamber, and the air outlet of the air self-circulation system 7 is connected to the paint spraying chamber.

[0026] In operation, exhaust gas is generated in the spray booth and passes through a water curtain filtration mechanism. In this mechanism, the exhaust gas first comes into contact with the water curtain on the water curtain plate 2. Through the initial purification effect of the water curtain, some pollutants in the exhaust gas are absorbed by the water. Subsequently, the exhaust gas enters the purification chamber, where multiple staggered baffles 3 form multiple water curtains. The exhaust gas entering the purification chamber sequentially comes into contact with these multiple water curtains for purification. After purification, the exhaust gas enters the air self-circulation system 7 through its air inlet. The air self-circulation system 7 is equipped with a circulating fan that re-sends the purified air into the spray booth, forming a circulation. This not only improves the purification efficiency of the exhaust gas but also saves energy. Simultaneously, the water tank assembly 4 provides a stable water flow to the water curtain plate 2 and baffles 3, and the wastewater tank 5 collects the wastewater flowing down from the water curtain plate 2 and baffles 3. After treatment by the wastewater filtration system 6, suspended solids, grease, and other pollutants are removed, allowing the wastewater to meet recycling standards. The wastewater filtration system 6 and the water tank assembly 4 are connected by an inlet pipe 9 to achieve water recycling.

[0027] This invention effectively reduces the use of water scrubbing towers by employing a water curtain filtration mechanism and an air self-circulation system 7, thereby lowering long-term operating costs. Simultaneously, the device has a compact structure and relatively small size, reducing the potential risk of damage to the factory roof structure and minimizing additional maintenance and repair costs. By setting multiple staggered baffles 3, the contact area between exhaust gas and water flow is increased, improving the purification effect of the exhaust gas. Furthermore, the downward-sloping baffles 3 facilitate the downward flow of water to form a water curtain.

[0028] In this embodiment, the water tank assembly 4 includes a water tank body 41, and a water outlet 42 is provided on one side of the water tank body 41. A water flow regulating device is provided at the water outlet 42.

[0029] Specifically, the water flow regulating device can take many forms. The water flow regulating device in this application includes an regulating plate 43 installed at the outlet 42. The regulating plate 43 is detachably and adjustablely connected to the water tank body 41. When the position of the regulating plate 43 is moved, the size of the outlet 42 can be changed.

[0030] In practical applications, staff can adjust the position of the regulating plate 43 by loosening bolts and other fasteners to change the size of the outlet 42, thereby adjusting the density and flow rate of the water curtain. This design not only improves the flexibility of the device but also makes the waste gas treatment effect more controllable and stable.

[0031] In this embodiment, an overflow port 44 is provided on the side of the water tank body 41, and the height of the overflow port 44 is higher than that of the water outlet 42.

[0032] Specifically, when the water level inside the water tank body 41 exceeds the height of the overflow port 44, the excess water will flow out from the overflow port 44, thereby preventing the water tank body 41 from being overfilled and overflowing, and ensuring the safe operation of the device.

[0033] The above design not only improves the safety of the device but also effectively prevents equipment damage or water waste caused by excessively high water levels. At the same time, the overflow port 44 allows staff to easily observe the water level inside the tank body 41, enabling timely replenishment or drainage operations and ensuring the stable operation of the device.

[0034] In this embodiment, the plurality of baffles 3 are staggered on the side walls of the water curtain plate 2 and the spray booth 1. One end of the baffle 3 is rotatably connected to the side wall of the water curtain plate 2 or the spray booth 1. The baffle 3 also includes a support rod 8 located below the baffle 3. One end of the support rod 8 is rotatably connected to the side wall of the water curtain plate 2 and the spray booth 1, and the other end of the support rod 8 is rotatably connected to the middle of the baffle 3.

[0035] Specifically, it needs to be explained that after the support rod 8 is adjusted to the correct position, the support rod 8 is fastened to the water curtain plate 2 or the side wall of the spray booth 1 by fasteners.

[0036] Specifically, the rotatable connection between the baffle 3 and the support rod 8 allows the angle and position of the baffle 3 to be flexibly adjusted according to actual needs. This design not only enhances the adaptability and flexibility of the device but also helps optimize the purification effect of the exhaust gas. For example, when the pollutant content in the exhaust gas is high, the contact time and contact area between the exhaust gas and the water flow can be increased by adjusting the angle and position of the baffle 3, thereby improving the purification efficiency.

[0037] Furthermore, the rotating connection design facilitates maintenance and cleaning of the device. Workers can easily disassemble and reinstall baffle 3 to thoroughly clean and inspect the interior of the device, ensuring it remains in good working order for extended periods. This design also reduces the difficulty and cost of maintenance and cleaning, improving the device's economy and practicality.

[0038] In this embodiment, the wastewater filtration system 6 and the water tank assembly 4 are connected by an inlet pipe 9, and a valve is provided on the inlet pipe 9.

[0039] Specifically, the valve can be used to control the opening and closing of the inlet pipe 9, thereby achieving flexible control over the water intake of the wastewater filtration system 6. In practical applications, operators can open or close the valve in a timely manner according to the wastewater treatment needs and the water level of the water tank component 4, to ensure the normal operation of the wastewater filtration system 6 and the rational use of water resources. This design not only improves the automation level of the device but also helps to save water resources and reduce operating costs.

[0040] In this embodiment, a fresh air supply system 10 is also included, the air outlet of which is connected to the paint spraying chamber.

[0041] Specifically, the fresh air supply system 10 provides fresh air to the spray booth, ensuring air circulation and freshness. The system is equipped with a fresh air fan and air filter, which introduces fresh outside air into the spray booth while filtering out dust, bacteria, and other harmful substances, ensuring the air quality meets the requirements for painting operations. This not only improves painting quality but also provides employees with a more comfortable and healthier working environment. Furthermore, the fresh air supply system 10 helps balance the air pressure within the spray booth, preventing exhaust gas leakage and further ensuring the effectiveness of exhaust gas treatment.

[0042] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
