1.1 When casting objects, a demoulding machine is required, and the formula of the demoulding machine is usually composed of cork powder, waste oil, and bone glue.

1.2 The casting process generates a certain temperature, the exhaust gas contains oil mist, and the dust is easily adhered to the pipeline wall. Dry filter material dust collectors cannot be used.

1.3 The casting process of certain parts generates sparks, which can cause the oil and viscous substances on the ventilation duct wall to catch fire and cause a fire.

1.4 In order to eliminate oil stains on the ventilation ducts, they will actively ignite and burn off the oil and dust adhering to the ventilation ducts every period of time.

1.5 Electrostatic precipitators have a good adsorption and purification effect on oil mist, but the bonded dust can wrap around the anode and cathode electrodes, making it difficult to clean them clearly. Occasional arcing can cause a fire.

1.6 Considering numerous complex situations, the most ideal dust removal method in the industry is to use a wet dust collector.

1.7 The wet dust collector is equipped with a scum salvage filter and a chain scraper to scrape out the oil sludge that has settled at the bottom of the water tank.

1.8 A combination of wet dust collector and activated carbon filter can also be added, mainly to solve the VOCS gas contained in the exhaust gas.Of course, plate and frame bag filters and HEPA filters can also be added to improve the final purification efficiency of exhaust gas.
