Description

Paint residue treatment system

This work is about the technical field of wastewater treatment, especially about a paint residue treatment system used in dust-free paint rooms of Class 100 or Class 10,000.

As the awareness of environmental protection gradually rises, most factories now prohibit the direct discharge of wastewater and waste gas generated in the production process. This is because the harmful substances in wastewater and waste gas will cause environmental pollution and endanger the health of organisms that come into contact with wastewater and waste gas. Therefore, most factories need to further purify wastewater and waste gas through wastewater and waste gas treatment equipment before they can be discharged, which can reduce the damage to the environment after wastewater and waste gas are discharged.

It is generally used in painting production lines, such as automobile, container, construction machinery, 3C products and other painting production lines. It is mainly used to wash the air in the spray booth working area with water through the action of the water pump during the painting operation to reduce the content of paint mist and solvent in the air to ensure the health and safety of workers and the quality of the product. The circulating water for painting contains paint mist, which contains a large amount of paint. In the existing technology, relevant fillers are generally added to make the paint mist form paint residue, and then the paint residue in the water is condensed and suspended to facilitate scraping or scraping. However, this method of adding relevant fillers also has the problem of consuming fillers, and may also extend other environmental problems.

Please refer to Figure 1 and Figure 2 together. Figure 1 is a schematic diagram of the structure of the paint residue treatment system of this invention. Figure 2 is a schematic diagram of the structure of the recovery device of the paint residue treatment system of this invention. The paint residue treatment system 2 of this invention is applied to the dust-free positive pressure painting process of Class 100 and Class 10,000, to treat the paint mist and paint residue by gasification and mixing, and the water used can be recycled.

As shown in the figure, the paint residue treatment system 2 of the present invention is applied to a painting room 1. The painting room 1 includes a receiving room 3, an aeration room 4 and a recovery device 5.

The receiving chamber 3 is connected to the painting chamber 1. The receiving chamber 3 has a wastewater space 31 for receiving the objects to be processed from the painting chamber 1. Furthermore, the bottom of the wastewater space 31 is preferably arranged to be gradually tilted from high to low in the direction from the painting chamber 1 to the sump 51. In addition, a cleaning room 11 may be provided on one side of the painting chamber 1, and the cleaning room 11 may have a cleaning door for relevant personnel to enter. The cleaning room 11 is located above part of the receiving chamber 3; that is, one end of the receiving chamber 3 is connected to the painting chamber 1, and the top of part of the receiving chamber 3 is connected to the cleaning room 11, and the cleaning room 11 is connected to the painting chamber 1.

The waterfall chamber 4 is arranged above a part of the receiving chamber 3 and on a part of the side thereof; that is, the wastewater space 31 and the side of the receiving chamber 3 have waterfall chambers 4 arranged in parallel. The waterfall chamber 4 has a plurality of waterfall baffles 41 inside, and the plurality of waterfall baffles 41 are arranged obliquely from top to bottom. Preferably, the plurality of waterfall baffles 41 are arranged in series. The waterfall baffles 41 can preferably be water baffles (sheets).

The bottom of the blast chamber 4 is connected to the wastewater space 31, and the side is connected to the receiving chamber 3. The top of the blast chamber 4 is provided with an exhaust fan 42, and the bottom of the blast chamber 4 on the side opposite to the coating room 1 is provided with a paint residue liquid outlet 43. In other words, the top of the blast chamber 4 is provided with an exhaust fan 42, and the bottom is provided with an opening connected to the wastewater space 31 and a paint residue liquid outlet 43. Preferably, the bottom of the blast chamber 4 is provided with an opening connected to the wastewater space 31 on the side close to the cleaning room 11, and the paint residue liquid outlet 43 on the side away from the cleaning room 11. It is worth mentioning that the exhaust fan 42 may be provided with a first guide member, which is a plate body inclined downward from the cleaning room 11 to the direction away from the cleaning room 11; in addition, a second guide member may be provided at the opening of the waterfall chamber 4 connected to the wastewater space 31, one end of the second guide member is connected to the bottom of the wastewater space 31 or near the bottom, and is inclined upward from the cleaning room 11 to the direction away from the cleaning room 11 and then connected to an arc plate body.

By setting up the waterfall chamber 4, the high-speed airflow gasification effect is utilized. When the paint spray or dust air passes through the plurality of waterfall baffles 41 arranged in a sawtooth shape at high speed and enters the gasification mixing chamber to make a circular motion and generate centrifugal force, the spray and dust collide with the gasification mixing chamber and enter the water. The water droplets containing the spray and dust will be separated by the dewatering plate, and the clean air will be discharged by the exhaust fan 42. Therefore, the invention prevents the paint particles flying out of the workpiece from diffusing to the outside and polluting the environment through gasification mixing. In addition, the plurality of waterfall baffles 41 arranged in a saw-tooth shape can also collect pollutants such as paint particles through the liquid to the subsequent recovery device 5, thereby facilitating the corresponding treatment of pollutants such as paint particles.

It is worth mentioning that the upper part of the waterfall chamber 4 has an exhaust water-blocking space 44, and the plurality of waterfall baffles 41 are arranged below the exhaust water-blocking space 44. The space below the exhaust water-blocking space 44 in the waterfall chamber 4 gradually decreases in width from the coating room 1 to the water collecting tank 51. Preferably, the waterfall chamber 4 can be a vertical wall on the side far from the cleaning room 11, and an inclined wall on the side adjacent to the cleaning room 11, so that the recovered slag liquid treated by the plurality of waterfall baffles 41 is properly guided to the paint slag liquid water inlet 43, and then drained to the subsequent recovery device 5 through the first guide member.

The recovery device 5 is disposed at one side of the receiving chamber 3 and the waterfall chamber 4 and opposite to the coating chamber 1. Specifically, the recovery device 5 has a water collecting tank 51, which is connected to the paint residue liquid water inlet 43 to receive the recovered residue liquid after the material to be treated is treated by the plurality of waterfall baffles 41.

Thereby, the recovered residue liquid will be accommodated in the water collecting tank 51, and the paint residue in the recovered residue liquid will float on the liquid surface, thereby separating the paint residue and the liquid, and then recycling the liquid to the painting room 1 or adsorbing paint particles for processing.

In addition, the recovery device 5 includes a balancing water tank 53, which is located on the side of the water collecting tank body 51 opposite to the waterfall chamber 4, and a balancing water tank connecting pipe 54 is provided between the water collecting tank body 51 and the balancing water tank 53; wherein, the balancing water tank connecting pipe 54 can be provided, for example, near the top of the water collecting tank body 51 and the balancing water tank 53; the setting of the balancing water tank 53 can balance the water level, so that the waterfall is optimized, and then the paint residue particles are suspended to absorb paint particles, etc. By the way, the recovery device 5 can be provided with one or more vacuum motors to adjust the relevant liquid level balance, etc.; and a water replenishment area for replenishing circulating water.

The water collecting tank 51 has a reflux port 52, which is connected to the wastewater space 31 of the receiving chamber 3. The receiving chamber 3 is provided with a vortex reflux drive unit 32, which is located at the connection between the wastewater space 31 and the reflux port 52. With these configurations, the liquid can be recycled or the paint particles can be adsorbed in the wastewater space 31.

It is worth mentioning that the exhaust port 11 is connected to the inside of the blast chamber 4 in an airtight manner. The paint residue treatment system 2 includes an air supply pressure equalization unit 6, which is disposed above the painting chamber 1 and supplies air to the inside of the painting chamber 1. In this way, paint mist and paint residue can be treated efficiently.

The paint residue treatment system of the invention utilizes the high-speed airflow gasification effect of the waterfall chamber. When the paint spray or dust air passes through the multiple waterfall baffles 41 arranged in a sawtooth shape at high speed and enters the gasification mixing chamber to make circular motion and generate centrifugal force, the spray and dust collide with the gasification mixing chamber and enter the water. The water droplets containing the spray and dust will be separated by the dewatering plate, and the clean air will be discharged by the exhaust fan 42. Furthermore, the water level can be balanced by setting a balance water tank, so that the waterfall can be optimized, thereby allowing the paint residue particles to suspend and absorb paint particles, etc.

The above is for illustrative purposes only and is not intended to be limiting. Any equivalent modifications or changes made to the invention without departing from the spirit and scope of the invention shall be included in the scope of the patent application attached hereto.
