Description

[0002] Semi-dry method is a flue gas desulfurization and other pollutant treatment technology between wet method and dry method. The rotary atomizer atomizes the absorbent slurry (usually lime slurry, etc.) by high-speed rotation to form a large number of tiny and uniform droplets. These droplets are sprayed into the flue gas containing acidic pollutants such as sulfur dioxide. The droplets and flue gas are fully contacted and mixed, and the absorbent reacts chemically with sulfur dioxide to remove sulfur dioxide from the flue gas. At the same time, part of the water evaporates rapidly in the high-temperature flue gas environment, so that the final product is dry or semi-dry.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 8 The present invention provides a technical solution for a semi-dry desulfurization rotary atomizer:

[0040] A rotary atomizer for semi-dry desulfurization, comprising a support plate 1, a material storage barrel 2 and an external rod 9. By setting the external rod 9, the atomizer can be fixedly installed at a specified position. The external rod 9 and the material storage barrel 2 are fixedly installed together. A power mechanism 3 for providing power is arranged on the support plate 1. The power mechanism 3 includes a servo motor 31 fixedly connected to the top of the support plate 1.

[0041] A connection mechanism 4 for guiding the absorbent slurry into the storage barrel 2 is installed between the support plate 1 and the storage barrel 2. The connection mechanism 4 includes a conduit 42 that is rotatably connected to the inside of the support plate 1. A connection plate 41 is fixedly connected to the top of the conduit 42. A feed pipe 44 is coaxially arranged below the conduit 42. The conduit 42 and the feed pipe 44 are connected through a crown gear 33. The conduit 42 and the feed pipe 44 are connected through a bellows 43. The servo motor 31 and the connection plate 41 are connected through a gear set 32.

[0042] An anti-blocking mechanism 7 for preventing blockage is provided on the outside of the storage barrel 2. The anti-blocking mechanism 7 includes an atomizing upper plate 72 fixedly connected to the outside of the storage barrel 2, a partition 75 fixedly connected to the bottom of the atomizing upper plate 72, an atomizing lower plate 71 fixedly connected to the bottom of the partition 75, an opening and closing door 74 rotatably connected between the atomizing lower plate 71 and the atomizing upper plate 72, and the opening and closing door 74 is fixedly connected to a pinion gear 73 after penetrating the atomizing upper plate 72 through a rotating shaft;

[0043] A spray mechanism 6 is provided on the top of the atomizing upper disk 72. The spray mechanism 6 includes a spray gear 61 rotatably connected to the top of the atomizing upper disk 72. A spray groove 63 is provided inside the spray gear 61. A spray valve 62 is fixedly connected to the top of the spray gear 61. The spray valve 62 is connected to the spray groove 63. The spray groove 63 is connected to the external anti-corrosion coating through a pipeline.

[0044] The connecting plate 41 is fixedly connected to the support plate 1 through the fixing rod 5 , the outer side of the crown gear 33 is fixedly connected to the connecting plate 10 , the bottom of the connecting plate 10 is fixedly connected to the telescopic rod 11 , the telescopic rod 11 is fixedly connected to the spraying gear 61 , and the spraying gear 61 is meshed with the pinion 73 .

[0045] During operation, when in use, by starting the servo motor 31, the servo motor 31 drives the anti-blocking mechanism 7 to rotate through the gear set 32, the connecting plate 41, the conduit 42, the crown gear 33 and the storage barrel 2. After the anti-blocking mechanism 7 rotates, it will synchronously drive the atomizing lower plate 71 and the atomizing upper plate 72 to rotate. When the atomizing lower plate 71 and the atomizing upper plate 72 rotate, the absorbent slurry inside them will be quickly atomized and rotated out. The atomized absorbent slurry rotated out will contact the sulfur-containing flue gas, thereby chemically reacting with the sulfur in the sulfur-containing flue gas, and then absorbing the sulfur in the sulfur-containing flue gas.

[0046] As an embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the top of the connecting disk 41 is rotatably connected to a guide tube 12 for guiding external absorbent slurry into the storage barrel 2, the bellows 43 is arranged inside the crown gear 33, a feed groove is opened inside the feed pipe 44, and a distribution ball 45 is fixedly connected to the bottom of the feed pipe 44.

[0047] During operation, when the equipment is running, firstly, with the help of the guide pipe 12 and the connecting mechanism 4, the external absorbent slurry is introduced into the storage barrel 2 and the anti-blocking mechanism 7. After the absorbent slurry enters the connecting mechanism 4, it will flow through the connecting plate 41, the conduit 42 and the bellows 43 in sequence, and finally reach the feed pipe 44. In the feed pipe 44, the absorbent slurry will directly contact the distributor ball 45. After the diversion effect of the distributor ball 45, the absorbent slurry will enter the storage barrel 2 through the feed groove on the feed pipe 44. The presence of the distributor ball 45 can effectively prevent the absorbent slurry from gathering at the bottom of the feed pipe 44 or the bottom of the storage barrel 2.

[0048] As an embodiment of the present invention, Figure 3 , Figure 4 and Figure 7 As shown, a jet mechanism 8 for use with the anti-clogging mechanism 7 is installed on the top of the atomizing lower plate 71, and the jet mechanism 8 includes a support frame 82 fixedly connected to the top of the atomizing lower plate 71, a placement groove is opened inside the support frame 82, a sealing block 83 is slidably connected inside the placement groove, a spring 84 is fixedly connected to the bottom of the sealing block 83, an air bag 86 is fixedly installed inside the placement groove, a one-way valve 85 is provided at the air inlet of the air bag 86, and a blowing valve 87 passing through the support frame 82 is provided at the air outlet of the air bag 86, a pipeline connected to the external air is fixedly connected inside the support frame 82, a connecting rod 81 is fixedly connected to the bottom of the feed pipe 44, and the connecting rod 81 and the sealing block 83 are fixedly connected.

[0049] After the atomizer has been running for a period of time, the atomizing lower plate 71 and the atomizing upper plate 72 may be blocked due to factors such as excessive absorbent slurry concentration, coarse particles, or impurities that are not fully dissolved. At this time, the servo motor 31 is first controlled to reverse at a low speed. After the servo motor 31 reverses at a low speed, it will drive the crown gear 33 to reverse through the connecting plate 41 and the conduit 42. When the crown gear 33 reverses, the gear piece on its top will maintain a normal rotation state. At this time, the top gear piece cannot drive the bottom gear piece to rotate, but will cause the bottom gear piece to move up and down, thereby causing the feed pipe 44 to move up and down. At the same time, when the top gear piece rotates, it will drive the spray gear 61 to rotate through the connecting plate 10 and the telescopic rod 11. After the spray gear 61 rotates, it will drive the small gear meshing with the outside. When the gear 73 rotates, the rotation of the pinion 73 will drive the opening and closing door 74 connected to the bottom thereof to rotate. After the opening and closing door 74 rotates, it can open the opening between the atomizing lower plate 71 and the atomizing upper plate 72, and can also break up or directly discharge the lumps of materials accumulated at the discharge port. In addition, during the up and down movement of the feed pipe 44, the connecting rod 81 and the sealing block 83 at the bottom will be synchronously driven to move up and down together. After the up and down movement of the sealing block 83, the gas inside the placement groove will be introduced into the air bag 86 through the one-way valve 85. When the gas in the air bag 86 reaches a certain pressure, it will be quickly discharged through the blowing valve 87. The discharged gas can cooperate with the rotation of the opening and closing door 74, which can not only blow out the solid particles inside the atomizing lower plate 71 and the atomizing upper plate 72, but also blow out the lumps that are broken up by the opening and closing door 74 and are difficult to discharge.

[0050] As an embodiment of the present invention, Figure 5 and Figure 6 As shown, an elastic plate 66 is fixedly connected to the inner wall of the spraying slot 63 , a push plate 64 is fixedly connected to the outer side of the elastic plate 66 , and a connecting cloth 65 is fixedly connected between the push plates 64 .

[0051] During operation, after running for a period of time, the reverse rotation speed of the servo motor 31 is increased. At this time, the storage speed of the gas in the airbag 86 is accelerated, and the rotation speed of the opening and closing door 74 is also increased, so as to more effectively remove the solid particles inside the atomizing lower plate 71 and the atomizing upper plate 72. At the same time, as the speed of the servo motor 31 increases, the speed of the spraying gear 61 also increases synchronously. After the speed of the spraying gear 61 increases, the centrifugal force on the push plate 64 increases. Under the action of the increased centrifugal force, the push plate 64 will drag the elastic plate 66 outward. Since a connecting cloth 65 is provided between the push plates 64, the push plates 64 can move the spraying slot 63 when they move outward. The anti-corrosion paint inside is compressed, and when the pressure reaches a specific value, the anti-corrosion paint will be sprayed out through the spray valve 62 (the pressure setting of the spray valve 62 is a prior art and is common knowledge for those skilled in the art), and the sprayed anti-corrosion paint will cover the outer surface of the atomizer, and with the help of the vibration force generated by the crown gear 33, the anti-corrosion paint can be more evenly covered on the rated outer surface of the atomizer. In addition, when the anti-corrosion paint is not sprayed out from the spray valve 62, the vibration force generated by the crown gear 33 will cause the anti-corrosion coating on the surface of the atomizer to fall off quickly, so that the anti-corrosion paint sprayed next time can better adhere to the outer surface of the atomizer.

[0052] Working principle: When working, the external absorbent slurry is first introduced into the storage barrel 2 and the anti-blocking mechanism 7 through the guide pipe 12 and the connecting mechanism 4. The absorbent slurry entering the connecting mechanism 4 will first pass through the connecting plate 41, the guide tube 42 and the corrugated tube 43 to enter the feed pipe 44. The absorbent slurry entering the feed pipe 44 will directly touch the dividing ball 45. After the absorbent slurry is diverted by the dividing ball 45, it will enter the storage barrel 2 through the feeding groove on the feed pipe 44. The dividing ball 45 can prevent the absorbent slurry from gathering at the bottom of the feed pipe 44 or the bottom of the storage barrel 2.

[0053] When in use, the servo motor 31 is started. After the servo motor 31 is started, the anti-blocking mechanism 7 is driven to rotate through the gear set 32, the connecting plate 41, the conduit 42, the crown gear 33 and the storage barrel 2. After the anti-blocking mechanism 7 rotates, it will synchronously drive the atomizing lower plate 71 and the atomizing upper plate 72 to rotate. When the atomizing lower plate 71 and the atomizing upper plate 72 rotate, the absorbent slurry inside them will be quickly atomized and rotated out. The atomized absorbent slurry rotated out will contact the sulfur-containing flue gas, thereby chemically reacting with the sulfur in the sulfur-containing flue gas, and then absorbing the sulfur in the sulfur-containing flue gas.

[0054] After the atomizer has been used for a period of time, the atomizing lower plate 71 and the atomizing upper plate 72 may be blocked due to excessive concentration of the absorbent slurry, too coarse particles, or impurities that are not fully dissolved. At this time, the servo motor 31 is first controlled to reverse at a low speed. After the servo motor 31 reverses at a low speed, it will drive the crown gear 33 to reverse through the connecting plate 41 and the conduit 42. After the crown gear 33 reverses, the gear piece on its top will rotate normally. At this time, the top gear piece cannot drive the bottom gear piece to rotate but drives the bottom gear piece to move up and down. Therefore, the bottom gear piece will drive the feed pipe 44 to move up and down. When the top gear piece rotates, it will drive the spray gear 61 to rotate through the connecting plate 10 and the telescopic rod 11. After the spray gear 61 rotates, it will drive the outer meshing small gear 73 to rotate When the pinion 73 rotates, it will drive the opening and closing door 74 connected to the bottom to rotate. After the opening and closing door 74 rotates, it can open the opening between the atomizing lower plate 71 and the atomizing upper plate 72, and can also break up or directly discharge the accumulated material lumps at the discharge port. At the same time, the up and down movement of the feed pipe 44 will synchronously drive the connecting rod 81 and the sealing block 83 at the bottom to move up and down. After the sealing block 83 moves up and down, the gas inside the placement groove will be introduced into the air bag 86 through the one-way valve 85. When the gas in the air bag 86 reaches a certain pressure, it will be quickly depressurized and discharged through the blowing valve 87. The discharged gas can cooperate with the rotation of the opening and closing door 74, not only to blow out the solid particles inside the atomizing lower plate 71 and the atomizing upper plate 72, but also to blow out the lumps that are broken up by the opening and closing door 74 and are difficult to discharge;

[0055] After a period of time, the speed of the servo motor 31 in the reverse direction is increased. At this time, the gas in the airbag 86 is stored faster, and the rotation speed of the opening and closing door 74 is also accelerated, so as to better remove the solid particles inside the atomizing lower plate 71 and the atomizing upper plate 72. At the same time, the speed of the servo motor 31 is increased, and the speed of the spraying gear 61 is also increased synchronously. The increase in the speed of the spraying gear 61 will increase the centrifugal force of the push plate 64. When the centrifugal force of the push plate 64 increases, it will drag the elastic plate 66 outward. Since the connecting cloth 65 is provided between the push plates 64, the push plates 64 can be moved outward. The anti-corrosion paint inside the spray tank 63 is compressed. When the pressure reaches a certain value, the anti-corrosion paint will be sprayed out through the spray valve 62. The anti-corrosion paint that has not been sprayed out through the spray valve 62 will cover the outer surface of the atomizer, and the vibration force generated by the crown gear 33 will make the anti-corrosion paint more evenly cover the rated outer surface of the atomizer. At the same time, in the process when the anti-corrosion paint is not sprayed out from the spray valve 62, the vibration force generated by the crown gear 33 will make the anti-corrosion coating on the surface of the atomizer fall off quickly, thereby facilitating the anti-corrosion paint sprayed next time to better adhere to the outer surface of the atomizer.

[0056] It should be noted that the anti-corrosion coating is a protective coating made of wax materials (such as paraffin, microcrystalline wax, etc.). It uses the hydrophobic, moisture-proof and isolation properties of the wax itself to achieve corrosion protection. After the wax is coated on the outside of the atomizer, it will fill the tiny pores on the metal surface to form a dense protective film, which prevents corrosive substances from penetrating into the metal matrix, thereby protecting the atomizer from corrosion. The adhesion between the wax coating and the metal surface is not very strong. When appropriate vibration is used, such as using special vibration equipment to generate low-frequency, high-amplitude vibration waves transmitted to the surface of the atomizer, the wax coating can gradually peel off from the surface under the action of vibration, making it easier to re-spray later. Because the atomizer rotates at high speed when working, after the atomizer has been working for a period of time, the anti-corrosion coating on its surface will cause friction with the flue gas, causing part of the anti-corrosion coating to fall off.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
