Detailed description of the preferred embodiments
A waste gas pretreatment filter device comprises a shell 1, a primary filter chamber 17, a secondary filter chamber 19, a settling chamber 18, a partition plate 11 and other main components. The shell 1 is provided with a support leg 2, an air inlet 3, an exhaust port 4, a sewage draining outlet 5, an access door 8, a filter element replacing door 7, a mounting lifting lug 10 and a pressure relief opening 9. A multi-stage baffle 12 is arranged in a first-stage filter chamber 17, two layers of baffle plates 16 and three layers of filter screens 13 are arranged in a second-stage filter chamber 19, the baffle plates 16 are fixed in the second-stage filter chamber 19 through clamping grooves 15, and the filter screens 13 are fixed in the second-stage filter chamber 19 through U-shaped clamping grooves 14.
The waste gas filtering device is a device without power source, waste gas enters the air inlet 3 of the filtering device through a pipeline under the power of negative pressure or positive pressure of a fan, the waste gas moves forwards continuously, larger particle dust in the waste gas can be intercepted by the baffle 12 in the first-stage filtering chamber 17, the waste gas moves forwards continuously, the intercepted larger particle particles can fall into the settling chamber 18, the waste gas enters the baffle plate 16 when passing through the second-stage filtering chamber 19, and the baffle plate 16 can effectively intercept impurities such as smaller particles, oil mist, water vapor and the like in the waste gas under the action of airflow force. The exhaust gas continues to move forward, and when passing through the wire mesh filter element 13, the wire mesh filter element 13 further intercepts smaller particles, oil mist and water vapor in the exhaust gas, and the exhaust gas is discharged into the exhaust gas purification equipment through the exhaust port 4. Less particulate matters, oil mist and water vapor intercepted by the screen filter element 13 are gathered to generate oil stain and water and other sediments which can be settled in the settling chamber 18 under the action of gravity, the bottom of the settling chamber 18 is provided with the drain outlet 5, the drain outlet 5 can be matched with the installation valve, and the sediments in the settling chamber 18 are discharged out of the filter through the drain outlet 5.
One or two baffles 16 in the exhaust gas pretreatment filtering device can be selectively installed according to the working condition of the exhaust gas, two or three screen filter elements 14 can be selectively installed, and the other baffles 16 and screen filter elements 13 which are not installed are used as spare parts.
After the waste gas pretreatment filtering device is used for a certain time, particulate matters and oil stains can be remained in the baffle plate 16, the screen filter element 13 and the settling chamber, as long as the filter element replacing door 7 is opened, the baffle plate 16 and the screen filter element 13 in the secondary filtering chamber 19 are drawn out through the clamping groove 15 and the U-shaped clamping groove 13, the baffle plate 16 and the screen filter element 13 are washed by water, the filter element replacing door is closed after the filter element is completely washed and inserted into the secondary filtering chamber 19 through the clamping groove 15 and the U-shaped clamping groove 13.
