Description

Technical Field

[0001] The present invention relates to the field of boiler flue gas treatment, and in particular to an industrial boiler flue gas intelligent treatment device and method based on solar energy. Background Art

[0002] The smoke and sulfur dioxide emitted by industrial boilers are one of the biggest sources of atmospheric pollution. Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, SO2, N2, O2, CO, CO2 hydrocarbons and nitrogen oxides, and the smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is a complex pollution of multiple poisons. The harm of smoke to the human body is related to the size of the particles. Most of the harm to the human body is caused by floating dust with a diameter of less than 10 microns, especially 1-2.5 microns. The current status of the industry is that steam boilers burn coal to produce a large amount of sulfur dioxide waste gas and smoke, and alumina production processes produce a large amount of alkaline Bayer red mud. In the prior art, the treatment of sulfur dioxide flue gas usually uses a desulfurizer to purify the sulfide therein.

[0003] At present, the flue gas treatment device has the following defects during use: 1. The flue gas is directly introduced into the static desulfurizer through a smoke inlet and cannot be in uniform contact with the desulfurizer, which can easily affect the speed of sulfide purification in the flue gas; 2. After the sulfide and desulfurizer react and are purified, a large amount of calcium sulfate precipitate will be produced. If it is not cleaned and recycled in time, it will not only easily cause scaling on the inner wall of the treatment box, but also the calcium sulfate precipitate cannot be recycled, which can easily cause waste of resources. Summary of the invention

[0004] The purpose of the present invention is to address the problems that the existing flue gas treatment devices cannot make the flue gas and desulfurizer contact evenly, affecting the flue gas treatment speed, and the calcium sulfate precipitate generated by the flue gas treatment cannot be cleaned and recovered, which not only easily adheres to the inner wall of the treatment box but also causes waste of resources.

[0018] The present invention also discloses a method for using a solar-powered industrial boiler flue gas intelligent treatment device, comprising the following steps:

[0019] S1: Add desulfurizer to the treatment box, and then evenly pass the flue gas into the treatment box through the smoke inlet assembly. The harmful sulfides in the flue gas are purified by the desulfurizer. At this time, the cylinder is started to drive the extraction frame to move up and down through the piston rod. The upward moving extraction frame will rotate and tilt through the cooperation of the baffle and the top rod, and the desulfurizer mixed with the flue gas can be lifted and poured out, thereby increasing the contact strength between the desulfurizer and the flue gas and purifying the flue gas thoroughly.

[0020] S2: When the extraction frame moves up and down, the wire rope will pull the winding wheel and the transmission rod to rotate back and forth, and the transmission rod will drive the stirring rod and the spoiler to rotate through the first pulley to stir the flue gas in the treatment box, so that the flue gas can further contact with the desulfurizer evenly and be purified and filtered;

[0021] S3: When the stirring rod rotates, it will also drive the rotating rod to rotate back and forth through the second pulley, and the rotating rod will drive the blocking plate to rotate back and forth to intermittently block the smoke exhaust pipe, so that the purified flue gas can be discharged intermittently, thereby increasing the retention time of the flue gas inside the treatment box, making it easier for the desulfurizer to completely purify the harmful substances in the flue gas;

[0022] S4: After the flue gas is purified and desulfurized, calcium sulfate precipitate will be produced. At this time, the waste liquid in the treatment box is discharged, and the sealing plate is pulled out to open the discharge port. The calcium sulfate precipitate will roll down to the elastic pad inside the drying box through the guide plate. At this time, the pulling mechanism is started to continuously pull the elastic pad through the pull rope to bounce the calcium sulfate precipitate, so that the calcium sulfate precipitate can be taken out for use after drying;

[0023] S5: starting the second motor to drive the rotating tube and the clapper to rotate and break up the calcium sulfate precipitate that bounces up, and cooperating with the blower structure to blow air into the drying box, so that the broken calcium sulfate precipitate is evenly contacted with the air, thereby increasing the drying speed of the calcium sulfate precipitate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] After the desulfurizer is added into the treatment box, the flue gas can be evenly passed into various positions inside the desulfurizer through the set extraction frame. The set cylinder can drive the extraction frame to move up and down, and cooperate with the baffle and the top rod to make the upward moving extraction frame flip to both sides, so that the desulfurizer can be extracted and then poured out, so that the desulfurizer is always in a flowing state, increasing the contact strength between the flue gas and the desulfurizer, which is convenient for the desulfurizer to thoroughly purify the harmful sulfides in the flue gas.

[0026] When the extraction frame moves up and down, it can also rotate back and forth by pulling the transmission rod through the suspension rope. The first pulley can drive the stirring rod and the spoiler to rotate, so that the flue gas inside the treatment box can be stirred, which further facilitates the thorough reaction of the flue gas and the desulfurizer. Moreover, when the stirring rod rotates, it can also drive the rotating rod and the sealing plate to rotate back and forth through the second pulley, so that the smoke exhaust pipe can be intermittently blocked, thereby increasing the residence time of the flue gas in the treatment box, and further facilitating the desulfurizer to purify the sulfide in the flue gas thoroughly.

[0027] Because calcium sulfate precipitate will be produced after the sulfide in the flue gas is purified by the desulfurizer, the waste liquid in the treatment box is discharged at this time, so that the calcium sulfate precipitate rolls through the guide plate to the elastic pad in the drying box. At this time, the pull rope can be pulled by the pulling mechanism, so that the elastic pad can continuously bounce the calcium sulfate precipitate. At the same time, the hair dryer mechanism can blow air onto the bounced calcium sulfate precipitate, which is convenient for quickly drying the calcium sulfate precipitate, so that the calcium sulfate precipitate can be recycled, which can not only avoid scaling of the inner wall of the treatment box, but also save resources.

DETAILED DESCRIPTION

[0040] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0041] like Figures 1 to 5As shown, this embodiment proposes an intelligent treatment device and method for industrial boiler flue gas based on solar energy, comprising a treatment box 1 and a drying box 2 arranged on the side wall of the treatment box 1, characterized in that a guide plate 101 of a tilting mechanism is provided on the inner bottom wall of the treatment box 1, and a discharge port connected to the drying box 2 is provided on the inner wall of the treatment box 1, and a sealing plate 103 is slidably provided on the inner wall of the discharge port, and also comprises a mixing mechanism, a flipping assembly and a smoke inlet assembly, the mixing mechanism comprises a cylinder 3 arranged at the bottom of the treatment box 1, a piston rod 301 arranged at the output end of the cylinder 3, and an extraction frame 4 rotatably arranged on the top of the piston rod 301, the flipping assembly comprises a box body 201 arranged at the bottom of the drying box 2, an elastic pad 6 arranged on the inner wall of the drying box 2, a pull rod 7 slidingly arranged on the inner bottom wall of the drying box 2 through the box body 201, a pull rope 701 arranged between the pull rod 7 and the elastic pad 6, and a pulling mechanism arranged inside the box body 201, and the smoke inlet assembly is arranged between the treatment box 1 and the extraction frame 4, and is used to evenly discharge the smoke into various positions inside the treatment box 1;

[0042] Add desulfurizer into the treatment box 1, and then evenly pass the flue gas into the treatment box 1 through the smoke inlet component, and purify the harmful sulfides in the flue gas through the desulfurizer. At this time, start the cylinder 3 to drive the extraction frame 4 to move up and down through the piston rod 301, which can not only extract the desulfurizer up and down but also stir the desulfurizer, thereby increasing the contact strength between the desulfurizer and the flue gas and purifying the flue gas thoroughly; and after the flue gas is purified and desulfurized, calcium sulfate precipitate will be produced. At this time, the waste liquid in the treatment box 1 is discharged, and the sealing plate 103 is pulled out to open the discharge port. The calcium sulfate precipitate will roll onto the elastic pad 6 inside the drying box 2 through the guide plate 101. At this time, start the pulling mechanism to continuously pull the elastic pad 6 through the pull rope 701 to bounce the calcium sulfate precipitate, so that the water stains on the calcium sulfate precipitate can be dried and taken out for recycling.

[0043] like Figure 5 , Figure 6 and Fig. 9 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a connecting plate 5 is provided on the top of the piston rod 301, two sets of extraction frames 4 are rotatably arranged on both sides of the connecting plate 5 through a rotating shaft, a baffle 401 is provided on the side wall of the extraction frame 4, and a top rod 402 matched with the baffle 401 is provided on the inner wall of the processing box 1, and a fixing plate 501 is provided on both sides of the bottom of the connecting plate 5, and a first spring 502 is connected between the fixing plate 501 and the bottom of the extraction frame 4;

[0044] When the cylinder 3 works and drives the connecting plate 5 to move upward through the piston rod 301, it can drive the extraction frame 4 to move upward to lift the desulfurizer. The extraction frame 4 will lift part of the desulfurizer, and when the baffle 401 is against the top rod 402, the extraction frame 4 will continue to move upward, it will be blocked by the top rod 402 and flip downward to squeeze the first spring 502. At this time, the desulfurizer in the extraction frame 4 will be poured out and collide with the desulfurizer at the bottom of the treatment box 1, and then the cylinder 3 drives the connecting plate 5 and the extraction frame 4 to move downward through the piston rod 301. The force of the first spring 502 is released and drives the extraction frame 4 to flip upward to reset. The desulfurizer can be continuously lifted and then poured down in a cycle, so that the desulfurizer can be kept in a flowing state, which further facilitates the desulfurizer to purify the sulfide in the flue gas more quickly and thoroughly.

[0045] like Figure 1 , Figure 3 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a heat-insulating cavity is opened in the inner wall of the processing box 1, and the smoke inlet assembly includes a smoke inlet pipe 13 arranged on the outer wall of the processing box 1 and connected to the heat-insulating cavity, and an air pipe 403 arranged between the inner wall of the processing box 1 and the extraction frame 4, wherein a cavity is arranged inside the extraction frame 4, and evenly distributed smoke exhaust holes are arranged on the lower surface of the extraction frame 4;

[0046] The flue gas is first discharged into the insulation chamber through the smoke inlet pipe 13. The insulation chamber can insulate the interior of the treatment 1, thereby increasing the processing speed of the sulfidizing agent on the flue gas. The flue gas passing through the insulation chamber will then pass through the air pipe 403 into the cavity inside the extraction frame 4, and finally be discharged into the desulfurizer from the smoke exhaust hole at the bottom of the extraction frame 4, thereby enabling the flue gas to evenly pass into various positions inside the desulfurizer, making it easier for the desulfurizer to quickly and thoroughly purify the sulfides in the flue gas.

[0047] like Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a spoiler assembly is provided inside the processing box 1, and the spoiler assembly includes a stirring rod 9 rotatably arranged on the inner walls of both sides of the processing box 1, a spoiler plate 901 arranged on the rod wall of the stirring rod 9, and a rotating member arranged on the rod wall of the stirring rod 9;

[0048] The rotating member includes a transmission rod 10 rotatably arranged on the inner wall of the processing box 1, a winding wheel 1001 arranged on the rod wall of the transmission rod 10, a hanging rope 1002 arranged between the winding wheel 1001 and the connecting plate 5, a first pulley 1003 arranged between the transmission rod 10 and the stirring rod 9, and a second spring 1004 serially connected to the rod wall of the transmission rod 10;

[0049] When the connecting plate 5 moves downward, it will pull the winding wheel 1001 and the transmission rod 10 through the suspension rope 1002 to rotate and twist the second spring 1004. When the connecting plate 5 moves upward, the suspension rope 1002 will be loosened. At this time, the second spring 1004 will drive the transmission rod 10 to reverse and reset. The transmission rod 10 will drive the stirring rod 9 and the spoiler 901 to reciprocate through the first pulley 1003. The flue gas in the treatment box 1 can be stirred through the spoiler 901, so that the flue gas and the desulfurizer can contact more evenly, thereby facilitating further thorough purification of the flue gas.

[0050] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a smoke exhaust assembly is further provided on the top of the processing box 1, and the smoke exhaust assembly includes a smoke exhaust pipe 102 arranged on the top of the processing box 1, a rotating rod 11 rotatably arranged on the side wall of the smoke exhaust pipe 102, a blocking plate 1101 arranged on the rod wall inside the smoke exhaust pipe 102, and a second pulley 12 that is transmission-arranged between one end of the stirring rod 9 located outside the processing box 1 and the rotating rod 11;

[0051] When the stirring rod 9 reciprocates, it will also drive the rotating rod 11 to reciprocate through the second pulley 12. The rotating rod 11 will intermittently block the smoke exhaust pipe 102 through the blocking plate 1101, allowing the smoke to be discharged intermittently, thereby increasing the residence time of the smoke in the treatment box 1, and further facilitating the thorough purification of sulfides in the smoke.

[0052] like Figure 5 and Figure 7 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the pulling mechanism includes a first motor 8 arranged on the inner wall of the box body 201, a cam 801 arranged on the output end of the first motor 8, a roller 702 rotatably arranged on one end of the pull rod 7 located inside the box body 201 and in contact with the cam 801, and a third spring 703 serially connected to the rod wall of the pull rod 7 located inside the box body 201;

[0053] Starting the first motor 8 can drive its output cam 801 to rotate until the small end contacts the roller 702, which will squeeze the pull rod 7 to move upward and compress the third spring 703. When the cam 801 rotates to the large end contacting the roller 702, the force on the third spring 703 is released, which will drive the pull rod 7 to move downward and reset. Therefore, the pull rod 7 will pull the elastic pad 6 up and down through the pull rope 701, so that the elastic pad 6 can continuously bounce and bounce up the calcium sulfate precipitate on its surface, so as to facilitate the drying of the calcium sulfate precipitate.

[0054] like Figure 3 , Figure 4 , Figure 8 and Fig.10As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a flapping mechanism is provided inside the drying box 2, and the flapping mechanism includes a second motor 14 arranged on the outer wall of the drying box 2, a rotating tube 1401 connected to the output end of the second motor 14, and a plurality of flappers 1402 arranged on the rotating tube 1401, wherein a cavity connected to the rotating tube 1401 is provided inside the flapper 1402, and air outlet holes evenly distributed are opened on the surface of the flapper 1402, and a blower mechanism connected to the rotating tube 1401 is also provided on the top of the drying box 2;

[0055] The air blowing mechanism comprises a fan 16 arranged on the top of the drying box 2, a rotating sleeve 15 rotatably connected to the outside of the rotating tube 1401, and a connecting tube 1601 connected between the output end of the fan 16 and the rotating sleeve 15, wherein a connecting groove is arranged inside the rotating sleeve 15, an air inlet hole is arranged on the outer wall of the rotating tube 1401 located inside the connecting groove, a box door is arranged on the side wall of the drying box 2, and an air outlet pipe is also arranged on the side wall of the drying box 2 near the bottom;

[0056] When the elastic pad 6 continuously bounces the calcium sulfate precipitate, the second motor 14 can be started to drive the rotating tube 1401 to rotate. The rotating tube 1401 will then drive each group of clappers 1402 to rotate and slap the bounced calcium sulfate precipitate, so as to further shake off the water stains on the calcium sulfate precipitate. The fan 16 can also be started to discharge the wind through the connecting tube 1601 to the connecting groove in the rotating sleeve 15, and then continue to enter the cavity in the clapper 1402 through the air inlet hole on the rotating tube 1401, and then blow out from the air outlet hole on the surface of the clapper 1402, so as to evenly blow the wind onto the calcium sulfate precipitate that collides with the clapper 1402, so as to further dry the moist calcium sulfate precipitate. Finally, the box door is opened to take out the dried calcium sulfate precipitate for recycling.

[0057] The present invention also discloses a method for using a solar-powered industrial boiler flue gas intelligent treatment device, comprising the following steps:

[0058] S1: Add desulfurizer to the treatment box 1, and then evenly pass the flue gas into the treatment box 1 through the smoke inlet assembly, and purify the harmful sulfides in the flue gas through the desulfurizer. At this time, the cylinder 3 is started to work to drive the extraction frame 4 to move up and down through the piston rod 301. The upward moving extraction frame 4 will rotate and tilt through the cooperation of the baffle 401 and the top rod 402, and can lift and pour out the desulfurizer mixed with the flue gas, thereby increasing the contact strength between the desulfurizer and the flue gas and purifying the flue gas thoroughly;

[0059] S2: When the extraction frame 4 moves up and down, the wire reel 1001 and the transmission rod 10 are pulled to rotate back and forth through the suspension rope 1002, and the transmission rod 10 drives the stirring rod 9 and the spoiler 901 to rotate through the first pulley 1003 to stir the flue gas in the treatment box 1, so that the flue gas can further contact the desulfurizer evenly and be purified and filtered;

[0060] S3: When the stirring rod 9 rotates, it will also drive the rotating rod 11 to rotate back and forth through the second pulley 12, and the rotating rod 11 will drive the blocking plate 1101 to rotate back and forth to intermittently block the smoke exhaust pipe 102, so that the purified flue gas is intermittently discharged, thereby increasing the retention time of the flue gas inside the treatment box 1, so that the desulfurizer can completely purify the harmful substances in the flue gas;

[0061] S4: After the flue gas is purified and desulfurized, calcium sulfate precipitate will be produced. At this time, the waste liquid in the treatment box 1 is discharged, and the sealing plate 103 is pulled out to open the discharge port. The calcium sulfate precipitate will roll onto the elastic pad 6 inside the drying box 2 through the guide plate 101. At this time, the pulling mechanism is started to continuously pull the elastic pad 6 through the pull rope 701 to bounce the calcium sulfate precipitate, so that the calcium sulfate precipitate can be taken out for use after drying;

[0062] S5: Start the second motor 14 to drive the rotating tube 1401 and the clapper 1402 to rotate and break up the calcium sulfate precipitate that bounces up, and cooperate with the wind blown into the drying box 2 by the blower structure to make the broken calcium sulfate precipitate contact with the wind evenly, thereby improving the drying speed of the calcium sulfate precipitate.

6. A method for using a solar-based intelligent treatment device for industrial boiler flue gas according to any one of claims 1 to 5, characterized in that: The following steps are involved: S1: adding a desulfurizing agent to the treatment box (1), and then evenly passing the flue gas into the treatment box (1) through the smoke inlet assembly, and purifying the harmful sulfides in the flue gas through the desulfurizing agent. At this time, the cylinder (3) is started to work, and the extraction frame (4) is driven to move up and down through the piston rod (301). The upwardly moving extraction frame (4) will rotate and tilt through the cooperation of the baffle (401) and the top rod (402), so that the desulfurizing agent mixed with the flue gas can be lifted and poured out, thereby increasing the contact strength between the desulfurizing agent and the flue gas, and thoroughly purifying the flue gas; S2: When the extraction frame (4) moves up and down, the wire reel (1001) and the transmission rod (10) are pulled by the suspension rope (1002) to rotate back and forth, and the transmission rod (10) drives the stirring rod (9) and the spoiler (901) to rotate through the first pulley (1003) to stir the flue gas in the treatment box (1), so that the flue gas can further contact the desulfurization agent evenly and be purified and filtered; S3: When the stirring rod (9) rotates, it also drives the rotating rod (11) to rotate back and forth through the second pulley (12), and the rotating rod (11) drives the blocking plate (1101) to rotate back and forth to intermittently block the smoke exhaust pipe (102), so that the purified flue gas is discharged intermittently, thereby increasing the retention time of the flue gas inside the treatment box (1), making it easier for the desulfurizer to completely purify harmful substances in the flue gas; S4: After the flue gas is purified and desulfurized, calcium sulfate precipitate is produced. At this time, the waste liquid in the treatment box (1) is discharged, the sealing plate (103) is pulled out, and the discharge port is opened. The calcium sulfate precipitate rolls onto the elastic pad (6) inside the drying box (2) through the guide plate (101). At this time, the pulling mechanism is started to continuously pull the elastic pad (6) through the pull rope (701) to bounce the calcium sulfate precipitate, so that the calcium sulfate precipitate can be taken out for use after drying; S5: starting the second motor (14) to drive the rotating tube (1401) and the clapper (1402) to rotate and break up the calcium sulfate precipitate that bounces up, and cooperating with the blower structure to blow air into the drying box (2) so that the broken calcium sulfate precipitate is evenly contacted with the air, thereby increasing the drying speed of the calcium sulfate precipitate.
