Description

Technical Field

[0001] The invention relates to the technical field of waste gas purification, and in particular to a waste gas purification device for a boiler. Background Art

[0002] The spray tower is an environmentally friendly equipment used for industrial waste gas treatment. It is mainly used to remove particulate matter and some soluble gaseous pollutants in the gas. Its working principle is based on the contact and reaction between the liquid and the waste gas in the tower. The waste gas enters from the bottom of the tower, and the liquid is sprayed downward from the top of the tower. The two are in countercurrent contact. With the assistance of the filler, the contact area is greatly increased, so that the impurities in the waste gas adhere to the surface of the filler, thereby improving the absorption and purification efficiency of the impurities in the waste gas.

[0003] During the waste gas purification process of the existing spray tower, the packing inside is in a static state. When the waste gas passes through the packing, the impurities in the waste gas adhere to the surface of the packing. As the waste gas purification work continues, the impurities in the waste gas gradually accumulate on the surface of the packing, causing the air flow channel on the packing to be blocked by the accumulated impurities, resulting in poor gas circulation, and gradually reducing the purification effect and efficiency of the waste gas.

[0004] Furthermore, since the packing in the existing spray tower is arranged in multiple layers, when the exhaust gas enters the spray tower, most of the impurities in the exhaust gas come into contact with the lower packing and adhere to its surface, and the upper packing can only absorb a small part of the impurities in the exhaust gas, resulting in low utilization rate of the upper packing.

[0035] Furthermore, in order to enhance the guiding and collecting effect of the interception plate 401 on impurities, the interception plate 401 is arranged to be inclined toward the recovery pipe 402 side.

[0036] A rotating plate 1003 is rotatably connected to the spray tower 1 .

[0037] The present invention drives the filler inside the purifier 2 to rotate during the process of purifying the exhaust gas, and uses the sprayed solution to flush and clean the filler, thereby solving the problem that the filler at the bottom is blocked by impurities in the exhaust gas due to the filler being in a static state inside the spray tower 1, resulting in reduced gas circulation effect. The specific process is as follows:

[0038] When purifying the exhaust gas generated in the boiler, firstly control the circulating water tank 201 to transfer the purified solution to the upper spray pipe 202 and the lower spray pipe 203, and then the upper spray pipe 202 and the lower spray pipe 203 spray downward on the outer ring surface and the inner ring surface of the purifier 2 respectively, and then control the motor 101 to drive the first gear 102 to rotate, and make the inner gear ring 103 drive the purifier 2 to rotate clockwise in the spray tower 1 based on the view from the front to the back, so that the filler in each filling cavity 2001 rotates together with the purifier 2, and then the exhaust gas generated in the boiler is transferred to the spray tower 1 through the air inlet 1001. After entering the spray tower 1, the exhaust gas first contacts with the filler in the filling cavity 2001 at the lower part of the purifier 2 in the rotating state. The filler has a porous structure, so that the path of the exhaust gas becomes longer and the speed slows down when passing through the filler. The impurities in the exhaust gas are fully in contact with the solution sprayed from the lower spray pipe 203, and then separated from the exhaust gas and adhered to the filler, thereby performing preliminary purification on the exhaust gas. As the exhaust gas continues to move upward, when the exhaust gas contacts the lower side of the guide plate 4, the exhaust gas is guided to the filling cavity 2001 in the purifier 2 on the side where the two guide plates 4 are separated through the guide plate 4, so that the exhaust gas flows upward along the filling cavity 2001 on the side where the two guide plates 4 are separated and passes through the through holes on each partition plate 3 in turn. At the same time, the exhaust gas is purified by the solution sprayed from the upper spray pipe 202, so that the exhaust gas is fully in contact with the filler in each filling cavity 2001, thereby enhancing the purification effect on the exhaust gas.

[0039] As the purifier 2 rotates, the fillers in each filling cavity 2001 rotate in turn and pass under the lower spray pipe 203 to contact the exhaust gas that has just entered the spray tower 1. As the purifier 2 continues to rotate, the fillers on the outer annular surface of the purifier 2 are flushed and cleaned by the solution sprayed from the upper spray pipe 202 when passing through the upper spray pipe 202, and the fillers on the inner annular surface of the purifier 2 are flushed and cleaned by the solution sprayed from the lower spray pipe 203 when passing through the lower spray pipe 203, so as to prevent impurities in the exhaust gas. Continuous accumulation on the filler prevents the filler from being blocked by the accumulated impurities, ensures smooth flow of gas through the purifier 2, and improves the purification effect of the boiler exhaust gas. At the same time, the filler is driven to rotate by the purifier 2, so that all the fillers can adsorb the exhaust gas just entering the spray tower 1, thereby improving the utilization rate of the filler. The sprayed solution contacts the filler in the purifier 2 and flows to the lower part of the spray tower 1, and is then sucked into the circulating water tank 201 for filtration and purification, and then sprayed from the upper spray pipe 202 and the lower spray pipe 203, so that the solution circulates to spray the exhaust gas.

[0040] When the purifier 2 rotates to purify the boiler exhaust gas, the purifier 2 drives the partition 3 to rotate clockwise. When the partition 3 rotates to contact the guide rod 301, the protrusion 3001 is supported by the guide rod 301. As the purifier 2 drives the partition 3 to continue to rotate clockwise, Figure 4 As shown, the partition 3 gradually slides toward the outside of the purifier 2 under the guidance of the guide rod 301, and at the same time, the elastic rope 302 is stretched to connect the filling chamber 2001 with the reserved chamber 2002. As the partition 3 continues to slide toward the outside of the purifier 2, the gap at the connection between the filling chamber 2001 and the reserved chamber 2002 gradually increases, and the filler in the filling chamber 2001 gradually enters the reserved chamber 2002 through the gap opened by the partition 3. In this process, the high-pressure solution sprayed by the high-pressure pipe 303 flushes the surface of the filler in the transfer process, deeply cleans the filler, reduces impurities adhering to the surface of the filler, enhances the capture effect of the filler surface on impurities in the exhaust gas, further improves the purification effect of the boiler exhaust gas, and prolongs the service life of the filler, which is conducive to prolonging the service life of the filler. Compared with the method of gradually opening the partition 3 to gradually increase the gap between the filling chamber 2001 and the reserved chamber 2002, if the partition 3 is directly opened to the maximum extent, the filler in the filling chamber 2001 will pile up and enter the reserved chamber 2002, so that the flushing and cleaning effect of the high-pressure solution sprayed by the high-pressure pipe 303 on the filler will be reduced. In this way, the filler is transferred by gradually opening the partition 3, and the filling chamber 2001 after the filler is discharged is transformed into a new reserved chamber 2002, ready to transfer the filler in the next filling chamber 2001. When the partition 3 passes through the guide rod 301 as the purifier 2 rotates, the partition 3 is reset under the elastic force of the elastic rope 302 to re-separate the filler in the purifier 2.

[0041] When the high-pressure pipe 303 deeply cleans the filler entering the reserved cavity 2002 from the filling cavity 2001, the impurities flushed from the filler pass through the filter screen on the inner ring surface of the purifier 2 and fall onto the interception plate 401. The interception plate 401 intercepts the impurities flushed down and discharges the impurities along the interception plate 401 through the recovery pipe 402 to the impurity collection device, preventing the impurities from falling directly to the lower part of the inner ring surface of the purifier 2, and preventing the filler at the lower part of the purifier 2 from being adhered to by the impurities flushed down, thereby ensuring the adsorption and purification effect of the filler rotated to the lower part of the purifier 2 on the impurities in the exhaust gas. After passing through the purifier 2, the exhaust gas continues to flow upward and enters the subsequent exhaust gas purification process through the exhaust port 1002 for deep purification.

[0042] When it is necessary to replace the packing inside the purifier 2, stop pumping exhaust gas into the spray tower 1, then the staff turns open the rotating plate 1003, removes the filter on the outer ring surface of the purifier 2, pours out the packing for replacement, and realizes convenient replacement of the packing. After the replacement is completed, reinstall the filter on the outer ring surface of the purifier 2, and turn and close the rotating plate 1003, and the exhaust gas evolution work can be resumed.

[0043] Embodiment 2: Based on embodiment 1, Figure 3-Figure 6As shown, it also includes a second gear 501 and a cleaning rod 502; the cleaning rod 502 is rotatably connected in the spray tower 1; the cleaning rod 502 is located on the inner ring surface of the purifier 2; a plurality of bristles 50201 are arranged on the cleaning rod 502; the second gear 501 is fixedly connected to the cleaning rod 502; the second gear 501 is meshed with the inner gear ring 103.

[0044] The cleaning rod 502 is provided with two protrusions 50202 in a circular array.

[0045] During the process of the filler entering the reserved cavity 2002 from the filling cavity 2001, the filler is flushed by the high-pressure pipe 303, so that the impurities on the filler pass through the filter on the inner ring surface of the purifier 2 and fall onto the interception plate 401 for collection. In this process, some impurities adhere to the filter on the inner ring surface of the purifier 2, causing the impurities to accumulate on the filter, affecting the purification effect of the purifier 2 on the exhaust gas. At this time, the second gear 501 is driven clockwise by the inner gear ring 103 to rotate counterclockwise, so that the second gear 501 drives the cleaning rod 502 to rotate counterclockwise, and the filter on the inner ring surface of the purifier 2 is brushed and cleaned by the bristles 50201 on the cleaning rod 502, so that the brushed impurities fall onto the interception plate 401 for collection, thereby reducing the impurities adhering to the filter on the inner ring surface of the purifier 2. The impurities on the inner ring surface of the purifier 2 are removed, which enhances the circulation effect of the airflow, and the impurities adhered to the outer ring surface filter of the purifier 2 are directly rinsed and cleaned through the upper spray pipe 202 and the high-pressure pipe 303. When using the bristles 50201 for cleaning, the bristles 50201 are inserted into the filter screen on the inner ring surface of the purifier 2 to move the filler in the filling cavity 2001 into the reserved cavity 2002. At the same time, the protrusion 50202 is driven by the cleaning rod 502 to intermittently collide with the filter screen on the inner ring surface of the purifier 2, and the filler in the filling cavity 2001 is vibrated to loosen, which facilitates the transfer of the filler in the filling cavity 2001 to the reserved cavity 2002, prevents the filler from being stuck in the filling cavity 2001, ensures the deep cleaning effect of the filler, and further improves the purification effect of the filler on the boiler exhaust gas.

The temperature in the heating furnace is controlled to be 850℃;

[0049] 3. Compressed sulfur dioxide gas (purity 99%) is fed into the air preheater together with compressed air through a gas cylinder. The flow rate and ventilation time of sulfur dioxide gas are adjusted by using a flow meter to control the molar ratio of Ca / S in the reactor to be 1.0, 1.5, 2.0, 2.5, and 3.0 respectively;
