The utility model has the advantages that:
1. the device has the advantages of small purification resistance, long service life, convenient disassembly and easy maintenance, can adjust the optimal purification efficiency according to the working environment and the smoke concentration, improves the purification effect and efficiency of the smoke, and has low energy consumption.
2. Be equipped with the adjusting bolt of adjustment degree of compressing tightly on the adjusting pressure pole, can adjust the degree of compressing tightly of filter screen through control adjusting bolt, and then carry out filtration efficiency's regulation, make adjusting pressure pole push down the frame when rotatory adjusting bolt, when pressing the frame and pushing down the filter screen, the clearance between the three-layer filter screen diminishes, and the ventilation resistance between the filter screen strengthens, and corresponding adhesion efficiency strengthens, and filtration efficiency improves. When the adjusting bolt is rotated to be loosened, the opposite is true. Can be reasonably adjusted according to the working environment and the smoke concentration, and improves the purification effect and efficiency of the smoke.
3. And the left sides of the independent units at odd positions are communicated with the air inlet static pressure chamber, and the right sides of the independent units at even positions are communicated with the air exhaust static pressure chamber. The structural design can effectively ensure that the flue gas enters the smoke and dust filter chamber from the air inlet static pressure chamber and then enters the exhaust static pressure chamber from the smoke and dust filter chamber and then is discharged, and the flue gas can be completely purified by the oil screen filter, thereby ensuring the effective purification effect.
4. The filter screen is formed by superposing three layers of oil immersion corrugated stainless steel filter screens. This kind of structural design can be so that smoke and dust in the flue gas and fine particle are broken up by the filter screen after by the effectual adhesion of the machine oil on the filter screen and catch, purifying effect is good.
