The arrows in the drawings of the specification of the present application represent the flow direction of gas, liquid, mixture, etc.
The principle of this application does: when waste gas containing paint mist enters an air inlet and then enters the main shell, because a fan is positioned at the rear end of the equipment, the pressure of an outlet in the main shell is smaller than the pressure of the inlet and is influenced by pressure difference, liquid such as water enters a gas-liquid contact mechanism positioned below, gas and paint slag are pumped into the gas-liquid contact mechanism together and flow upwards along the wall body of the gas-liquid contact mechanism, namely S bends, the gas and the liquid are mixed together in the gas-liquid contact mechanism, a designed pore channel can influence the change of flow velocity, the gas-liquid mixture is in a boiling state, finally, the gas-liquid contact mechanism is discharged from the topmost end, the liquid falls into a liquid slag channel below under the action of gravity, and the paint slag floats on the water surface and is discharged from a paint slag discharge port; the air upwards passes through the water mist removal baffle plate and then enters the fan to be discharged, the water mist is intercepted by the water mist removal baffle plate, the 45-degree angle of the baffle plate is arranged in the clamping groove above the outlet of the extrusion explosion mechanism, and the access door is only required to be opened and taken out when the air mist removal baffle plate needs to be replaced.
The inlet end water level and the play water end water level pass through water level adjustment mechanism and adjust in this application, and water level adjustment mechanism is promptly: the water level regulator consists of a flashboard and a spiral lifting mechanism, and when the water level is higher than the flashboard, the height of the flashboard can be overflowed and discharged to determine the filtering efficiency, and the water level regulator can be adjusted as required.
In the application, the coating waste gas can reach 99% purification efficiency by using an RTO incineration process for treatment, so that the treatment is the first choice for treating the coating waste gas at the present stage, however, an RTO heat accumulator is easily blocked by paint particles, immeasurable danger and loss can occur in severe cases, a spray purifier is required to be added at the front end for intercepting by an additional primary-secondary high-efficiency filter, because the purification efficiency of the spray purifier is very low, the paint particles cannot be fully mixed with water of a spray tower due to the atomization of a spray gun, and the particles cannot be efficiently intercepted, so that the primary-secondary high-efficiency filter is frequently replaced, and the primary-secondary high-efficiency filter needs to be replaced for 24 hours basically, a gas-liquid contact mechanism is adopted in the application, namely, the solid particles in the paint-containing waste gas are subjected to solid-gas extrusion explosion by using a throat extrusion explosion principle, so that the particles and the liquid are fully mixed, the interception efficiency is increased and can reach 99%, particulate matters are fully intercepted, so that the service life of the high-efficiency filter in the junior middle school is prolonged to 168 hours to 336 hours; therefore, the filtering efficiency is effectively improved.
The prior spraying technology has the following defects: the spray tower is internally provided with fillers for forced gas-liquid mixing, however, paint particles are very viscous, the surfaces of the fillers are easily pasted, and the fillers cannot be cleaned in the later period. The utility model provides an do not use any filler in this application, after the gas-liquid left the throat, gas outgoing, the lacquer sediment is stayed in liquid, and crowded department of exploding wind speed is very high, has the scouring effect, can not cause the jam, does not have any consumptive material, more can not appear unable clearance and lead to the unable risk that uses of system, so solved how to make the lacquer sediment change exhaust technical problem.
The existing Venturi filter can achieve 95% of filtration and can realize high-efficiency filtration, but the height of a water layer is limited to be 2-5mm on a flat plate with the length of tens of meters, the requirement on manufacturing is very high, and the realization is difficult; in the application, the S bay and the like are used for extruding and exploding the water vapor, the water level adjusting devices with overflow are arranged at the inlet and the outlet, the water level is self-balanced, and the requirement on the water level is not high, so that the problem that the equipment is easy to manufacture is solved.
The application has the following main beneficial effects: higher purification efficiency, lower maintenance cost, easier discharge of paint slag, simpler equipment, easier manufacture and lower cost.
The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be construed as limiting the present invention. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
