Technical Field
The utility model belongs to spraying trade exhaust-gas treatment field relates to a carpenter paint spraying table side is aired exhaust and is added coating cloud separator.
Background
With the development of national economy, the paint spraying process becomes an important link in the surface treatment process of products in the furniture industry. Because the paint contains a certain amount of organic solvent as a dispersion medium, the organic solvent is volatilized to form organic waste gas in the paint spraying process, and atomized paint particles which do not reach the surface of an object in the spraying process are dispersed along with air flow to form paint mist, so that the generated paint spraying waste gas exists in two states of the paint mist and the organic waste gas.
The purification treatment of the waste gas that sprays paint should consider the separation of coating cloud and organic waste gas at first to guarantee follow-up waste gas purification treatment effect that sprays paint, make the enterprise can realize waste gas discharge to reach standard in process of production. The ministry of environmental protection of China clearly points out in technical specifications of industrial organic waste gas treatment projects released and implemented, and when the content of particulate matters in waste gas before entering a purification treatment device is higher than a limit value, pretreatment is carried out by adopting modes such as filtration or washing.
However, the treatment effect of the paint spraying waste gas generated in the existing spraying industry is not ideal, and the fundamental reason is that enterprises lack effective means to separate solid substances (resin, toner, curing agent and the like) in the generated paint mist from organic waste gas, so that an exhaust pipeline is blocked, and a series of problems such as low efficiency of a circulating system, failure of the surface of active carbon wrapped by paint, poisoning of a catalyst in a catalytic device and the like are caused.
The Chinese invention patent (CN209696486U) discloses a filter device for treating paint mist waste gas, which comprises a filter main body and a shell for accommodating the filter main body, wherein a first primary filter layer, a second primary filter layer, a middle filter layer and a high-efficiency filter layer are sequentially arranged in the filter main body along the direction from an air inlet to an air outlet, the first primary filter layer is paint mist felt, two ends of the first primary filter layer are respectively wound on a first rotating shaft and a second rotating shaft, the first rotating shaft and the second rotating shaft are fixed on the filter main body, a motor is further arranged in the filter main body, and the motor is connected with the first rotating shaft or the second rotating shaft. But the manufacturing method is complex, the filter layer needs to be replaced for many times in the long-term treatment process, and the operation cost is high.
The invention patent (CN109954352A) discloses a paint mist waste gas purifier, which comprises an overflow groove, a flashing plate, a water tank, a filter plate, a filter guiding grid and a water baffle plate, wherein the overflow groove is arranged in the middle of the purifier, liquid flowing from the filter guiding grid is collected and flows to the water tank along the flashing plate, the overflow groove is directly connected with the flashing plate, the filter plate comprises a vertical filter plate and a transverse filter plate, the vertical filter plate is arranged in the water tank, the transverse filter plate is arranged on the surface of the rear part of the water tank, the filter guiding grid and the water baffle plate are arranged on the upper part of the purifier, the filter guiding grid comprises a front filter grid and a rear filter guiding grid, a channel between the transverse filter plate and the front filter grid is a gas-water stirring channel, the water baffle plate comprises a transverse water baffle plate and an inclined water baffle plate, the filter guiding grid and the water baffle plate are sealed in a gas collection tank, and the top. But the manufacturing method is complex, paint slag is difficult to clean, and the using condition has certain limitation.
The Chinese invention patent (publication No. ZL201620062077.6) discloses a device for treating paint mist waste gas by a spraying method, which enables the paint mist waste gas to be fully mixed with a generated umbrella-shaped rotating water curtain under the action of spray water sprayed at high speed when the paint mist waste gas passes through a paint mist purification device, so that the paint mist originally suspended in the gas collides with each other and is rapidly increased in weight, and finally the aim of separating the paint mist from the waste gas is achieved. The treatment effect is better, but the paint mist airflow needs to be pulled upwards, and the energy consumption is higher.
The invention aims to design a woodworking paint spraying table side air exhaust and paint mist separation device which has high separation efficiency, lower operation and maintenance cost, is convenient for cleaning paint slag, and has low energy consumption and low pollutant emission.
