[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1

[0018] Reference Figure 1-4A test coke oven flue filter environmental protection device comprises a box body 1, a negative pressure fan 2 is connected to the top of the box body 1, a filtering mechanism is installed in the box body 1, a connecting block 3 is connected to the bottom of the box body 1, a connecting channel 4 is arranged in the connecting block 3, the outer side of the top of the connecting block 3 is arranged in an inclined shape, a plurality of supporting columns 5 are connected to the outer side of the top of the connecting block 3, a cap 6 is installed in the middle of the top of the plurality of supporting columns 5, the vertical projection of the cap 6 covers the connecting channel 4, a sealing plate 12 is installed on the box body 1, the filtering mechanism comprises a first filter plate 7 and a second filter plate 8 which are sequentially installed in the box body 1 from top to bottom, there is a gap between the first filter plate 7 and the second filter plate 8, two second filter plates 8 are arranged between them, the two second filter plates 8 are arranged obliquely, and the inclined tops of the two second filter plates 8 are both facing the negative pressure fan 2.

[0019] Combined with Figure 2-4 It can be seen that there is a gap between the several support columns 5 and the connecting channel 4, and the cap 6 is cone-shaped. Combined with the inclined setting of the two second filter plates 8, the dust and oil dripping from the top between the two second filter plates 8 will be blocked by the cap 6, and the oil and dust will fall into the box body 1 along the cap 6, so that there will not be too much oil in the connecting channel 4.

[0020] The setting of the negative pressure fan 2 can speed up the air flow inside the box 1, so that the smoke can pass through the two second filter plates 8 and the first filter plate 7 faster, thereby speeding up the speed of the device filtering the smoke, thereby reducing the probability of smoke clogging; the two second filter plates 8 are both ceramic filter plates, so that the corrosion resistance of the second filter plates 8 is better, thereby extending the service life of the two second filter plates 8; the first filter plate 7 is mainly used to adsorb impurities in the gas in the filtered smoke, so that the first filter plate 7 can set the filtering part as an activated carbon filter element.

[0021] By connecting this device with the experimental coke oven flue, the flue gas of the experimental coke oven flue will reach the inside of the box body 1 through the connecting channel 4, and then the flue gas will pass through the two second filter plates 8 and the first filter plate 7 in sequence, and then be discharged through the negative pressure fan 2. When the flue gas passes through the two second filter plates 8, the oil and dust in the flue gas will stay at the bottom of the two second filter plates 8. Combined with the two second filter plates 8 being set in an inclined shape, the oil and dust in the second filter plates 8 will fall along the direction of the two second filter plates 8, thereby reducing the probability of oil and dust reaching the cap 6, thereby reducing the probability of oil and dust entering the flue; the cap 6 set in combination is a pointed cone, and combined with the inclined setting of the two second filter plates 8, the dust and oil dripping from the top between the two second filter plates 8 will be blocked by the cap 6, and the oil and dust will fall into the box body 1 along the cap 6, so that there will not be too much oil in the connecting channel 4.

[0022] Example 2

[0023] Based on Example 1, optimization is performed. Figure 1-4 A connecting pipe 10 is provided on one side of the box body 1, and a scale line 11 is provided on the connecting pipe 10. The height of the scale line 11 is aligned with the top of the connecting block 3. A baffle 9 is installed on the box body 1 on one side of the connecting block 3. The height of the baffle 9 is higher than the height of the top of the connecting block 3, so that after the sealing plate 12 is removed, the dirt in the box body 1 will not leak out directly.

[0024] After adding water inside the box 1, the connecting pipe 10 is connected to the inside of the box 1, and the water inside the box 1 will display its height through the connecting pipe 10, so that the connecting pipe 10 can observe the accumulation of dust and oil in the box 1, thereby facilitating maintenance personnel to clean and maintain the device.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
