Abstract

[0002] Industrial silicon smelting flue gas refers to the high-temperature flue gas emitted by industrial silicon furnaces (usually submerged arc furnaces), which is referred to as industrial silicon furnace flue gas here. Since the flue gas from industrial silicon furnaces has high temperature, high dust content (mainly microsilicon powder) and contains harmful substances such as sulfur dioxide and nitrogen oxides, the flue gas from industrial silicon furnaces needs to be discharged after waste heat recovery, dust removal (for example, dust removal by flue gas filter dust collector), desulfurization (for example, desulfurization by dry desulfurization device) and denitrification (for example, denitrification by SCR denitrification reactor).
[0003] At present, the industrial silicon production field still generally uses traditional bag dust collectors as flue gas filtration dust collectors to purify the flue gas of industrial silicon furnaces after cooling. Since the bag filter element in the bag dust collector has weak high temperature resistance, low strength and poor thermal shock resistance, and the temperature fluctuation of the flue gas discharged during the operation of the industrial silicon furnace is relatively large, it is easy to cause the bag filter element to rupture.

[0046] The first filter plate 15 , the second filter plate 16 , the third filter plate 17 and the fourth filter plate 18 are all elastically slidably and sealingly connected with inner plates 23 .
[0047] The upper end of the inner plate 23 inside the first filter plate 15 protrudes above the first filter plate 15, and the upper end of the inner plate 23 inside the second filter plate 16 is tightly against the lower end of the first filter plate 15. The upper end of the inner plate 23 inside the third filter plate 17 is tightly against the lower end of the second filter plate 16. The upper end of the inner plate 23 inside the fourth filter plate 18 is tightly against the lower end of the third filter plate 17.

The filter holes 22 of the fourth filter plate 18 are connected with the through holes 24 of the inner plate 23 inside it.
[0048] After the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 are rotated to enclose a sealed rectangular channel, the filter holes 22 of the first filter plate 15 are misaligned with the through holes 24 of the inner plate 23 thereof, the filter holes 22 of the second filter plate 16 are misaligned with the through holes 24 of the inner plate 23 thereof, the filter holes 22 of the third filter plate 17 are misaligned with the through holes 24 of the inner plate 23 thereof, and the filter holes 22 of the fourth filter plate 18 are misaligned with the through holes 24 of the inner plate 23 thereof.
[0049] An elastic rubber layer is fixed to one end of the fourth filter plate 18 away from the third filter plate 17 .
[0050] Specifically, the inner plate 23 in the first filter hole 22 is connected to the first filter plate 15 through a spring 25, the inner plate 23 in the second filter hole 22 is connected to the second filter plate 16 through a spring 25, the inner plate 23 in the third filter hole 22 is connected to the third filter plate 17 through a spring 25, and the inner plate 23 in the fourth filter hole 22 is connected to the fourth filter plate 18 through a spring 25.
[0051] During operation, treatment liquid is added into the box body 1, and the fan 6 is started. The exhaust gas enters the box body 1 through the inlet pipe 2. The exhaust gas entering the box body 1 is washed by the treatment liquid and then enters the treatment box 7 through the connecting pipe 4. The exhaust gas entering the treatment box 7 is filtered by the filter element and then discharged through the outlet pipe 35.
[0052] After the waste gas is washed with the treatment liquid, the impurities in the waste gas will float on the surface of the treatment liquid.
[0053] After the exhaust gas treatment is completed, the motor 8 is started, and the motor 8 drives the screw 9 to rotate, and the rotation of the screw 9 causes the slider 10 to move downward. Figure 3 As shown, the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 are in a vertical state.
[0054] After the slider 10 moves to the lower end of the slide cavity 34 , the first filter plate 15 , the second filter plate 16 , the third filter plate 17 and the fourth filter plate 18 are located below the liquid level of the treatment liquid in the box 1 .
[0055] The first telescopic rod 13 is started to retract the first telescopic rod 13, the second rotating block 14 approaches the first rotating block 12, and the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 rotate upward. When the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 are in a horizontal state in the box body 1, the impurities floating on the surface of the treatment liquid in the box body 1 are located above the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18. At this time, the elastic rubber layer on the fourth filter plate 18 is in sealing contact with the left side wall of the box body 1.
[0056] Then the motor 8 is started, and the motor 8 drives the screw 9 to rotate in the opposite direction to make the slider 10 rise, and the slider 10 drives the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 to rise. When the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 move to above the liquid surface of the treatment liquid in the box body 1, the impurities floating on the liquid surface of the treatment liquid are located above the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18.
[0057] like Figure 8 As shown, when the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 are in a horizontal state in the housing 1, the slider 10 is pressed against the inner plate 23 in the first filter plate 15, the first filter plate 15 is pressed against the inner plate 23 in the second filter plate 16, the third filter plate 17 is pressed against the inner plate 23 in the fourth filter plate 18, the spring 25 connected to the inner plate 23 is compressed, the filter hole 22 of the first filter plate 15 is communicated with the through hole 24 of the inner plate 23 inside thereof, the filter hole 22 of the second filter plate 16 is communicated with the through hole 24 of the inner plate 23 inside thereof, the filter hole 22 of the third filter plate 17 is communicated with the through hole 24 of the inner plate 23 inside thereof, and the filter hole 22 of the fourth filter plate 18 is communicated with the through hole 24 of the inner plate 23 inside thereof. After the first filter plate 15 , the second filter plate 16 , the third filter plate 17 and the fourth filter plate 18 move to above the level of the treated liquid in the housing 1 , the treated liquid containing impurities can pass through the filter holes 22 and the through holes 24 .
[0058] When the lower surface of the first filter plate 15 is flush with the top surface of the slide plate 28, the first telescopic rod 13 is activated to extend the first telescopic rod 13. When the first telescopic rod 13 is extended, the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 rotate downward. At the same time, the second telescopic rod 20 is activated to extend the second telescopic rod 20. When the second telescopic rod 20 is extended, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 rotate.
[0059] like Figure 5 As shown, when the first filter plate 15, the second filter plate 16, the third filter plate 17 and the fourth filter plate 18 are combined to form a rectangular channel, the rectangular channel is connected to the two rectangular holes, and the impurities are located inside the rectangular channel.
[0060] After the first filter plate 15 , the second filter plate 16 , the third filter plate 17 and the fourth filter plate 18 are combined to form a rectangular channel, the inner plate 23 loses its obstruction. Under the elastic force of the spring 25 , the inner plate 23 slides and causes the filter hole 22 to be misaligned with the through hole 24 .
[0061] Then start the water pump 27, which pumps external water into the water inlet channel 26. When the water pressure in the water inlet channel 26 increases, it will push the slide plate 28 into the rectangular channel and move the slide plate 28 toward the baffle 30. During the movement of the slide plate 28 toward the baffle 30, impurities in the rectangular channel can be scraped off.
[0062] When the slide plate 28 approaches the baffle plate 30, the magnet 29 on the slide plate 28 and the magnet 29 on the baffle plate 30 repel each other, and the slide plate 28 can generate thrust on the baffle plate 30 during subsequent movement. Subsequently, the slide plate 28 can drive the baffle plate 30 and the polished rod 31 to move and deform the tension spring 33 to store force. When the outlet of the drainage channel 32 is connected to the space between the baffle plate 30 and the slide plate 28, impurities are discharged through the outlet of the drainage channel 32.
[0063] When the slide plate 28 passes over the outlet of the drainage channel 32 , the water in the rectangular channel can be discharged through the outlet of the drainage channel 32 , thereby flushing the inner wall of the rectangular channel.
[0064] Keep water continuously injected into the rectangular channel to achieve continuous flushing of the inner wall of the rectangular channel.
[0065] After the rectangular channel inner wall is flushed, stop water filling in the rectangular channel. Under the promotion of the tension spring 33, the baffle plate 30 is restored.
[0066] Then the water pump 27 is started to pump out the water in the rectangular channel and the water inlet channel 26 . During the process of pumping out the water in the rectangular channel and the water inlet channel 26 , the slide plate 28 gradually slides to the initial position.
[0067] Then the second telescopic rod 20 is started to retract.
