Description

Technical Field

[0001] This utility model relates to the field of spray painting exhaust gas technology, specifically a spray painting exhaust gas cyclone separator and collection tank. Background Technology

[0002] Painting is essential in industrial production processes such as container manufacturing, automobile manufacturing, furniture manufacturing, and machinery manufacturing. This painting process requires the use of large quantities of organic solvents (such as thinner), which are emitted as waste gas. Currently, large-scale manufacturing industries both domestically and internationally generally treat painting waste gas using methods such as incineration and concentrated catalytic combustion. Incineration is extremely expensive to operate and consumes large amounts of fuel, making it unaffordable for many companies. Furthermore, the solvents cannot be recovered, and the resources cannot be reused.

[0003] Currently, other industries in China have adopted recycling methods to treat organic waste gas. However, the organic waste gas generated during the painting process is characterized by large volume, low concentration of volatile organic compounds, and high concentration of paint mist dust. Existing recycling and treatment technologies have the following drawbacks when applied to this type of waste gas: the airflow capacity is reduced after the filter becomes clogged, the air resistance increases, and the operating cost is increased; this waste gas contains a large number of particulate dust particles, which can easily enter the pores of the adsorbent, causing the adsorbent pores to become clogged and the adsorbent to quickly become ineffective.

[0004] To address this issue, the present invention provides a spraying waste gas cyclone separator and collection tank, which solves the aforementioned problems through a separation component and a conveying component. Utility Model Content

[0020] Furthermore, the conveying assembly 5 includes a connecting pipe 51, which is fixed to the top of the separation hopper 31.

[0022] Example 2: Please see Figure 1-2 This embodiment provides a technical solution based on embodiment one: the ventilation component 7 includes a support member 71, which is fixed to the top of the base plate 1 and near the right end. A servo motor 72 is fixedly connected to the top of the support member 71, and a rotating shaft 73 is fixedly installed at the output end of the servo motor 72.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] During operation, the exhaust gas first enters the separation component 3 through the air supply pipe 32. When the separation component 3 is working, the airflow enters the main body of the separation bucket 31 tangentially from the inlet of the separation bucket 31, forming a high-speed rotating vortex inside. The heavier powder particles are thrown towards the inner wall under the action of centrifugal force and spiral down along the inner wall to the bottom collection box 34. The air with residual ultrafine particles after separation is discharged from the conveying component 5. When the conveying component 5 is working, the air with residual ultrafine particles enters the cyclone 54 axially and generates strong rotation under the action of the guide component. It moves downward in a spiral shape along the air inlet pipe 61. The denser dust particles are thrown towards the wall under the action of centrifugal force and fall down along the air inlet pipe 61 under the action of gravity and are discharged from the bottom. The rotating airflow contracts and flows towards the center in the air inlet pipe 61, forming a secondary vortex upward and being sent to the liquid storage tank 4. The liquid storage tank 4 stores water through the liquid inlet pipe 9. The exhaust gas and water flow mix and adsorb, so that the paint mist and water are fully mixed and settled, resulting in high treatment efficiency. The ventilation component 7 works synchronously. The PLC controller starts the servo motor 72, which drives the blade 75 to rotate through the rotating shaft 73. This causes the air inside the liquid storage tank 4 to be discharged from the exhaust pipe 8 after passing through the connecting component 6. When passing through the air inlet pipe 61, it passes through the filter layer 64, which is an activated carbon layer. The porous structure of the activated carbon is used to adsorb VOCs in the exhaust gas. After saturation, the connecting component 6 needs to be regenerated or replaced. By controlling the air supply of the ventilation component 7, the residence time of the exhaust gas in the connecting component 6 can reach the adsorption time of the activated carbon layer.
