Furniture spray painting dust and paint mist treatment equipment

Furniture factories will generate paint spraying exhaust gas and dust exhaust gas generated by carpenters during the operation of push table saws, vertical milling tables, sanding machines, planers, drills, and polishing tables. These exhaust gases can cause air pollution and harm workers, so exhaust gas treatment in furniture factories is essential. So, what are the exhaust gas treatment plans for furniture factories? Next, Yuan and the editor will introduce dust and exhaust gas treatment solutions to you.

1. Filtering principle: Dust containing gas enters through the air inlet, and when passing through the ash hopper, some large particles of dust in the gas are separated by inertia and gravity, and directly fall into the bottom of the ash hopper. The dusty gas enters the filter bag filtration area of the middle box after passing through the ash hopper. The gas passes through the filter bag, and the dust is trapped on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag opening and is then discharged through the air outlet.

2. Dust cleaning principle: As the filtration time prolongs, the dust layer on the filter bag continues to accumulate, and the resistance of the dust removal equipment continues to rise. When the equipment resistance rises to the set value, the dust cleaning device begins to clean the dust.

Firstly, a compartment lift valve is closed to cut off the filtered airflow, and then the electromagnetic pulse valve is opened. Compressed air rapidly expands in the upper box in a very short time, flowing into the filter bag, causing the filter bag to expand and deform, generating vibration. Under the action of reverse airflow flushing, the dust attached to the outer surface of the filter bag is stripped off and falls into the ash hopper.

After the dust cleaning is completed, the electromagnetic pulse valve closes, the lift valve opens, and the chamber returns to the filtering state. The cleaning process is carried out sequentially in each room, starting from the cleaning of each room and ending with a cleaning cycle.

3. Dust collection: The dust intercepted by filtration and dust cleaning work falls into the ash hopper and is then discharged through the ash hopper mouth. Suitable exhaust gas treatment equipment can be planned, designed, and customized according to manufacturers in different industries, achieving one factory, one solution, which can effectively help enterprises economically and reasonably carry out environmental protection and safety protection work.
