Description

Technical Field

[0001] The present invention relates to the technical field of dust collectors, and particularly to a desulfurization dust collector with good energy-saving effect and its using method. Background Technique

[0002] For flue gas containing sulfur dioxide, it is mostly necessary to use a desulfurization dust collector for desulfurization treatment before discharge. However, most of the existing desulfurization dust collectors use calcium carbonate in limestone slurry to oxidize with sulfur dioxide and oxygen in the flue gas to produce calcium sulfate during use. And through the setting of limestone slurry, after the flue gas passes through the limestone slurry, some dust in the flue gas will come into contact with the limestone slurry, which is easy to block the filter screen or the air outlet pipe, and there are certain defects.

[0003] The defects existing in the existing desulfurization dust collectors are:

[0004] 1. Patent document CN217725052U discloses a desulfurization dust collector for metal wire mesh processing, including a desulfurization dust collector main body. A connecting pipe is connected to the outside of the desulfurization dust collector main body. A limiting mechanism is arranged on the outside of the desulfurization dust collector main body. A fixing pipe is installed on the outside of the desulfurization dust collector main body. One end of the fixing pipe is connected to a desulfurization chamber, and a supporting mechanism is arranged at the bottom of the fixing pipe; this device is provided with a limiting mechanism, which can ensure that the anti-slip pad firmly fits on the outside of the connecting pipe, and the anti-slip pad strengthens the limit on the outside of the connecting pipe, playing an auxiliary reinforcement role, and avoiding the problems that the connecting pipe is easy to deform and may affect the normal progress of desulfurization and dust removal; this device is provided with a supporting mechanism, which can ensure the stable supporting structure of the supporting sleeve, improve the support at the bottom of the fixing pipe, ensure the firm connection structure of the fixing pipe, and avoid the situation that the connection part of the fixing pipe is easy to loosen. However, the desulfurization dust collector in the above-mentioned published document mainly considers how to improve the connection stability of the fixing pipe, and does not consider that the existing desulfurization dust collectors are not convenient to disassemble and assemble during use, which is not conducive to dealing with the products during pipeline blockage and desulfurization treatment of flue gas, and has poor flexibility;

[0005] 2. Patent document CN216630384U discloses a wet flue gas desulfurization and dust removal device, which includes a supporting bottom plate. Four corners at the lower end of the supporting bottom plate are fixedly connected with universal wheels. A humidifying device is fixedly connected to the left part of the upper end of the supporting bottom plate. An air inlet pipe penetrates and is connected to the left end of the humidifying device. A mixing device is fixedly connected to the middle part of the upper end of the supporting bottom plate, and a pipe penetrates and connects between the mixing device and the humidifying device. A filter box is penetratively connected to the right part of the outer surface of the mixing device through a pipe. A heating module penetrates and is connected to the upper end of the filter box. The lower part of the right end of the heating module is penetratively connected to a fan through a pipe. An exhaust pipe penetrates and is connected to the right part of the outer surface of the fan. For the wet flue gas desulfurization and dust removal device of the present utility model, by setting the humidifying device and the mixing device, the whole wet flue gas desulfurization and dust removal device has high dust removal efficiency, good desulfurization effect and high stability, and is suitable for use in the process of flue gas desulfurization and dust removal. However, the desulfurization and dust removal device in the above-mentioned published document mainly considers how to improve the dust removal efficiency, and does not consider that the existing desulfurization and dust removal device is prone to pipeline blockage during use, and the practicability is poor;

[0006] 3. Patent document CN214261362U is specifically a multi-functional desulfurization and dust removal device, which includes an outer wall, a negative pressure chamber and a water tank. A dust storage cabin is fixed at the lower end of the outer wall. A dust discharge port is opened at the lowermost end of the dust storage cabin. Supporting legs are fixedly connected to the lower surface of the outer wall. A water tank is fixed at the lower end of the supporting legs. An alkaline solution is filled in the water tank. A water discharge pipe is fixedly connected to the left side of the water tank. The upper end of the water discharge pipe passes through the outer wall and is fixedly connected to a liquid storage cabin. A condensing pipe is arranged at the lower end inside the liquid storage cabin. The upper end of the left side of the condensing pipe is connected to a buffer spiral pipe. The present utility model has a circulating water use structure, which can reuse water and achieve the effect of water conservation. At the same time, a dust removal and desulfurization separation structure is set to solve the problem that the existing equipment treats dust and waste gas together, making the treated water mixed with a lot of impurities and difficult to reuse. However, the desulfurization and dust removal device in the above-mentioned published document mainly considers to simultaneously treat dust and waste gas by setting a circulating water use structure to achieve the purpose of water conservation, and does not consider that the existing desulfurization and dust removal device has poor energy-saving effect and high energy consumption during use;

[0007] 4. Patent document CN217725130U discloses a desulfurization dust collector, which includes a dust removal box filled with desulfurization liquid, an inlet pipe and an outlet pipe connected to the dust removal box. A box body is rotatably connected to the bottom inside the dust removal box, and air permeable holes are evenly distributed on the box body. A communicating pipe is vertically connected to the center of the upper side of the box body, and one end of the inlet pipe passes through the communicating pipe and is arranged inside the box body. The advantages of this utility model are as follows: This device passes the sulfur-containing waste gas into the box body, and then rotates the box body so that the sulfur-containing waste gas is discharged from the air permeable holes on the box body and fully mixed with the desulfurization liquid to fully desulfurize the waste gas. However, the desulfurization dust collector in the above-mentioned disclosed document mainly considers how to fully desulfurize the waste gas, and does not consider that the existing desulfurization dust collector does not have a circulating filtration device during use, resulting in low flue gas treatment efficiency.

The upper support plate is located below the lower connecting pipe.

[0022] Preferably, the usage method of this desulfurization dust collector is as follows:

[0023] S1. Before using this desulfurization dust collector, first insert the first filter mesh into the top of the air injection pipe as required, and fix the first filter mesh in the storage frame by the engagement of the first placement plate and the baffle. Then pour an appropriate amount of prepared limestone slurry into the storage frame. Through the setting of the first one-way valve, it can prevent the limestone slurry from flowing into the interior of the connection box;

[0024] S2. When using the main body of the desulfurization and dust removal device, first, pass flue gas into the main body of the desulfurization and dust removal device through the flue gas inlet pipe, and open the first electronic valve, so that the air inlet pipe can transport air into the connection box and spray it out through the spray pipe, so that the input air can gush out in the limestone slurry. At the same time, the passed-in flue gas will gush out from the limestone slurry;

[0025] S3. After the flue gas undergoes desulfurization treatment, it will successively pass through the activated carbon filter plate, three groups of high-efficiency filters two with different pore sizes, and the porous fiber block to continue secondary filtration, so as to reduce the proportion of dust and other harmful gases in the flue gas. Then, adsorb fine particles through the anode plate;

[0026] S4. During the desulfurization and dust removal process, regularly start the water pump, so that the water extraction pipe can extract the water in the water storage tank, and transport the water into the internal part of the booster pump through the water delivery hose for pressurization. Finally, transport the water into the internal part of the connecting pipe through the water delivery steel pipe, and finally spray the water on the surfaces of the anode plate and the high-efficiency filter two through the spray nozzles and atomizing nozzles on the surfaces of the two groups of water storage pipes.

[0027] Preferably, in the step S1, the following steps are further included:

[0028] S11. Then, insert the storage frame into the inside of the notch one, so that the insertion rod can be engaged with the jack, and make the sealing gasket fit with the surface of the main body of the desulfurization and dust removal device through the engagement of the insertion block and the slot, so that the sealing gasket can seal the connection between the notch one and the storage frame, and connect the air inlet pipe to an external air compressor;

[0029] In the step S2, the following steps are further included:

[0030] S21. During this process, sulfur dioxide in the flue gas will contact calcium carbonate in the limestone slurry and oxygen in the sprayed air to produce an oxidation reaction, generating calcium sulfate. When the calcium sulfate reaches a certain saturation, it will crystallize to form gypsum dihydrate. Through the settings of the first mesh plate and the first filter plate, the probability of blockage of the spray pipe can be reduced to a certain extent;

[0031] In the step S3, the following steps are further included:

[0032] S31. During this process, regularly start the electric heating plate, and then start the purge fan, so that the first delivery pipe can transport air into the inside of the heating box, and after passing through the electric heating plate, blow the heat to the porous ceramic regenerator, and finally transport it into the main body of the desulfurization and dust removal device through the second delivery pipe, so that the fed heating gas can be mixed with the filtered flue gas, and discharged into the inside of the first connection box through the slot holes, and transported into the second connection box through the smoke delivery pipe;

[0033] When using the heating box in the step S31, the following steps are further included:

[0034] S311. The purging blower blows hot air through the porous ceramic regenerator into the interior of the desulfurization dust collector main body, enabling the porous ceramic regenerator to store heat. When the electric heating plate is turned off, the purging blower can still blow hot air into the desulfurization dust collector main body, thus playing an energy-saving role to a certain extent and reducing resource consumption.

[0035] S32. During the process of the purified flue gas moving in the flue gas delivery pipe, a gas detector on the storage mesh frame is used to analyze and detect whether the purified flue gas meets the emission standards. If the detection is qualified, the second electronic valve opens, and at this time, the flue gas will be discharged through the exhaust pipe. Otherwise, the exhaust fan in the storage box starts, and then the flue gas in the second connection box can be pumped out through the first exhaust pipe, and the flue gas is pumped into the interior of the flue gas purification box through the second exhaust pipe. The sulfur dioxide and dust in the flue gas are filtered through the molecular sieve and the first high-efficiency filter screen, which can improve the efficiency of flue gas purification treatment to a certain extent.

[0036] In the step S4, the following steps are further included:

[0037] S41. At the same time, the ultrasonic transducer at the bottom of the support plate is started, and then the activated carbon filter plate, the second high-efficiency filter screen, and the porous fiber block can be driven to vibrate by the ultrasonic transducer, so that the dust adhering to the surfaces of the activated carbon filter plate, the second high-efficiency filter screen, and the porous fiber block can be shaken off, improving the cleaning efficiency, and further improving the efficiency and quality of subsequent flue gas purification to a certain extent.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. The present invention is equipped with a base, a desulfurization dust collector main body, a storage frame, a sealing gasket, a flue gas inlet pipe, a connection box, and an air inlet pipe. Before using the desulfurization dust collector, first pour limestone slurry into the storage frame and insert the storage frame into the notch. Then, through the engagement of the insertion rod and the insertion hole, the insertion block is engaged with the insertion slot. Then, the sealing gasket can be used to improve the sealing performance of the connection between the storage frame and the first notch. Then, the first electronic valve can be opened, and air is conveyed into the connection box through the air inlet pipe. Then, the flue gas can be conveyed into the interior of the desulfurization dust collector main body through the flue gas inlet pipe. At this time, the flue gas moves upward through the limestone slurry. At this time, the sulfur dioxide in the flue gas reacts with calcium carbonate in the slurry and the air ejected from the air injection pipe to generate calcium sulfate. When the calcium sulfate reaches a certain saturation, it crystallizes to form gypsum dihydrate. The detachable connection between the storage frame and the desulfurization dust collector main body facilitates the subsequent treatment of gypsum dihydrate and limestone slurry.

[0040] 2. The present invention is equipped with a jet pipe, a check valve I, a storage plate I, a mesh plate I, and a first filter mesh plate. Through the setting of the check valve I, the limestone slurry in the storage box can be intercepted outside the jet pipe. And through the settings of the mesh plate I and the first filter mesh plate, the gypsum dihydrate generated during the flue gas treatment process can be intercepted to a certain extent, thereby reducing the probability of the jet pipe being blocked by gypsum dihydrate, and further ensuring that the incoming flue gas can fully react oxidatively with the limestone slurry and air.

[0041] 3. The present invention is equipped with a storage plate II, a purge fan, a heating box, a delivery pipe II, a check valve II, a porous ceramic heat storage body, and an electric heating plate. When the flue gas enters the desulfurization and dust removal device main body and passes through layers of filtration, the purge fan and the electric heating plate are started, and the outside air is drawn into the interior of the heating box through the delivery pipe I. The drawn air can bring heat to the porous ceramic heat storage body after passing through the electric heating plate and is delivered to the interior of the desulfurization and dust removal device main body through the delivery pipe II, so that the blown hot air can heat-treat the purified flue gas and is discharged into the interior of the connection box I through the slot holes.

[0042] 4. The present invention is equipped with a connection box I, a flue gas delivery pipe, a connection box II, an exhaust pipe, a suction pipe I, a suction pipe II, a flue gas purification box, and a gas detector. After the flue gas enters the connection box I, it will enter the interior of the connection box II through the flue gas delivery pipe. During this process, the gas detector on the storage mesh frame will constantly detect whether the flue gas meets the emission standards. When it is detected that there is a large amount of sulfur dioxide in the flue gas, at this time, the exhaust fan is started, and then the flue gas can be drawn into the interior of the storage box through the suction pipe I, and the flue gas is transported into the interior of the flue gas purification box through the suction pipe II, and the sulfur dioxide and dust in the flue gas are filtered again through the molecular sieve and the high-efficiency filter mesh I. Otherwise, the single valve II is opened, and the flue gas in the connection box II will be discharged through the exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS

A smoke inlet pipe 10 penetrates through the inner part of the storage frame 6 and is installed on the outer surface of the sealing gasket 7. An air inlet pipe 12 is installed on the outer surface of the sealing gasket 7. One end of the air inlet pipe 12 penetrates through the inner part of the storage frame 6 and is connected to the top of the connection box 11. An electronic valve 1 is installed on the outer surface of the air inlet pipe 12. The insertion holes 4 are located on both sides of the notch 3. The two groups of slots 5 are respectively located above and below the notch 3. The insertion rods 9 are fitted with the insertion holes 4. The insertion blocks 8 are fitted with the slots 5. The size of the sealing gasket 7 is larger than that of the storage frame 6. The inner surface of the sealing gasket 7 is attached to the outer surface of the desulfurization dust collector main body 2. A baffle 16 is installed on the inner surface of the storage frame 6. A first placement plate 17 is placed on the top of the baffle 16 in an embedded manner. A notch 18 is penetrated through the top of the first placement plate 17. A first filter net 19 is installed on the inner surface of the first placement plate 17. Uniformly arranged air injection pipes 14 are installed on the top of the connection box 11. One-way valves 15 are installed inside both the smoke inlet pipe 10 and the air injection pipes 14. A first filter plate 20 is installed on the top of the air injection pipes 14 in an embedded manner. The baffle 16 is located below the smoke inlet pipe 10.

Then, the flue gas can be transported into the desulfurization dust collector main body 2 through the flue gas inlet pipe 10, and sulfur dioxide in the flue gas can react with oxygen in the air and calcium carbonate in the limestone slurry to produce an oxidation reaction. Then calcium sulfate can be generated, and when calcium sulfate is saturated to a certain extent, it crystallizes to form gypsum dihydrate and falls on the first wire mesh plate 19 and the first filter mesh plate 20. Through the setting of the first wire mesh plate 19 and the first filter mesh plate 20, the probability of blockage of the air spraying pipe 14 can be reduced to a certain extent. And through the detachable connection between the storage box 6 and the desulfurization dust collector main body 2, it is convenient for the subsequent treatment of gypsum dihydrate and limestone slurry.

[0058] Please refer to Figure 6 As shown in, an embodiment provided by the present invention: a desulfurization dust collector with good energy-saving effect, including a second placing plate 21 and an electric heating plate 28. The second placing plate 21 is installed on the outer surface of the desulfurization dust collector main body 2, and the second placing plate 21 is located above the side of the first notch 3. A purging blower 22 is installed on the top of the second placing plate 21. A heating box 24 is placed on the top of the second placing plate 21. The output end of the purging blower 22 is installed with a first conveying pipe 23. The front of the heating box 24 is installed with a second conveying pipe 25, and one end of the second conveying pipe 25 extends into the desulfurization dust collector main body 2. A check valve II 26 is installed inside the second conveying pipe 25. The inner wall of the heating box 24 is installed with an electric heating plate 28 and two groups of porous ceramic heat storage bodies 27 arranged front and back. The heating box 24 is located in front of the purging blower 22. One end of the first conveying pipe 23 is connected to the back of the heating box 24. The porous ceramic heat storage body 27 is located in front of the electric heating plate 28.

[0059] Further, after the flue gas is filtered in the main body 2 of the desulfurization dust collector, the electric heating plate 28 in the heating box 24 is started, and the purging fan 22 is started, so that the purging fan 22 can draw the outside air into the interior of the heating box 24 through the first conveying pipe 23. After the drawn air passes through the electric heating plate 28, the heat generated by the electric heating plate 28 can be blown into the interior of the porous ceramic heat storage body 27, and the heat is conveyed into the interior of the main body 2 of the desulfurization dust collector through the second conveying pipe 25, achieving the purpose of heating the flue gas. Through the setting of the check valve II 26, the flue gas in the main body 2 of the desulfurization dust collector will not enter the interior of the heating box 24. Under the action of the porous ceramic heat storage body 27, heat can be adsorbed, so that when the electric heating plate 28 is subsequently turned off, the purging fan 22 can still blow the heat into the interior of the main body 2 of the desulfurization dust collector to heat the flue gas, which can play an energy-saving role to a certain extent and improve the practicability of the main body 2 of the desulfurization dust collector.

[0060] Please refer to Figure 5 and Figure 8 As shown in [Figures] and [Figures], an embodiment provided by the present invention is: a desulfurization dust collector with good energy-saving effect, including a first connection box 29 and a first high-efficiency filter screen 41. A slot hole is provided through the top of the main body 2 of the desulfurization dust collector. The first connection box 29 is installed on the top of the main body 2 of the desulfurization dust collector, and the first connection box 29 is located outside the slot hole. A smoke delivery pipe 30 is installed on the outer surface of the first connection box 29. One end of the smoke delivery pipe 30 is installed with a second connection box 31. A support rod 32 is installed at the bottom of the second connection box 31. The bottom end of the support rod 32 is connected to the top of the second placement plate 21. The support rod 32 is located behind the purging fan 22. A smoke exhaust pipe 33 is installed at the top of the second connection box 31. An electronic valve II is installed on the outer surface of the smoke exhaust pipe 33. A flue gas purification box 37 is installed on the top of the first connection box 29. A molecular sieve 40 and a first high-efficiency filter screen 41 are installed on the inner wall of the flue gas purification box 37, and the first high-efficiency filter screen 41 is located above the molecular sieve 40. A storage box 34 is installed on the top of the smoke delivery pipe 30. An air extractor is installed inside the storage box 34. A first air extraction pipe 35 is installed on the back of the storage box 34. A check valve III is installed inside the first air extraction pipe 35.

Gas detectors 39 are installed on the front of both groups of placement mesh frames 38, and the gas detectors 39, the electronic valve II and the air extractor are electrically connected.

[0061] Further, when using the main body 2 of the desulfurization dust collector, after the flue gas is filtered and purified, it will enter the interior of the first connection box 29 through the slot holes, and the gas detector 39 on the storage net frame 38 is used to detect the flue gas at the inlet and outlet of the smoke delivery pipe 30. When it is detected that there is still a large amount of sulfur dioxide in the flue gas, the exhaust fan in the storage box 34 starts at this time. Then, the flue gas in the second connection box 31 can be pumped into the storage box 34 through the first suction pipe 35, and is transported into the interior of the flue gas purification box 37 through the second suction pipe 36, and the sulfur dioxide and dust in the pumped flue gas are filtered and adsorbed by the molecular sieve 40 and the first high-efficiency filter screen 41, and finally discharged. On the contrary, the second electronic valve opens, and then the flue gas in the second connection box 31 will be discharged through the exhaust pipe 33, which can improve the effect of flue gas treatment to a certain extent.

[0062] Please refer to Figure 7, an embodiment provided by the present invention: a desulfurization dust collector with good energy-saving effect, including an activated carbon filter plate 42 and an ultrasonic transducer 58. The inner wall of the desulfurization dust collector main body 2 is installed with an activated carbon filter plate 42, and the activated carbon filter plate 42 is located above the notch one 3. The inner wall of the desulfurization dust collector main body 2 is installed with three groups of high-efficiency filter meshes two 43 arranged at equal intervals, and the pore diameters of the three groups of high-efficiency filter meshes two 43 increase sequentially from top to bottom. The high-efficiency filter mesh two 43 is located above the activated carbon filter plate 42. The inner wall of the desulfurization dust collector main body 2 is installed with a porous fiber block 44, and the porous fiber block 44 is located above the high-efficiency filter mesh two 43. An anode plate 48 is installed inside the desulfurization dust collector main body 2. A connecting pipe 49 is installed on the inner surface of the desulfurization dust collector main body 2 in an up-and-down arrangement. Water storage pipes 45 are installed on one side surface of the two connecting pipes 49, and one end of the water storage pipe 45 is connected to the inner wall of the desulfurization dust collector main body 2. The anode plate 48 is located in the middle of the two water storage pipes 45. Uniformly arranged spray nozzles 46 are installed on the outer surface of the upper water storage pipe 45. Atomizing nozzles 47 are installed on the outer surface of the lower water storage pipe 45, and the atomizing nozzles 47 are located above the porous fiber block 44. A water storage tank 50 is installed on the top of the base 1. A water inlet 56 is provided through the top of the water storage tank 50. A water pump 51 and a booster pump 52 are installed on the top of the base 1 in a front-and-back arrangement, and the booster pump 52 is located in the middle of the desulfurization dust collector main body 2 and the water pump 51. The water pump 51 is located in the middle of the booster pump 52 and the water storage tank 50. The output ends of the two water pumps 51 are both installed with water suction pipes 53, and one end of the water suction pipe 53 extends into the interior of the water storage tank 50. The output ends of the two water pumps 51 are both installed with water delivery hoses 54, and one end of the water delivery hose 54 is connected to the input end of the booster pump 52. The output ends of the two booster pumps 52 are both installed with water delivery steel pipes 55, and one end of the water delivery steel pipe 55 penetrates through the interior of the desulfurization dust collector main body 2 and is connected to the other side surface of the connecting pipe 49. The two water delivery steel pipes 55 are respectively located above and below the placing plate two 21. The delivery pipe two 25 is located in the middle of the upper connecting pipe 49 and the anode plate 48. Uniformly arranged support plates 57 are installed on the inner wall of the desulfurization dust collector main body 2. An ultrasonic transducer 58 is installed at the bottom of the support plate 57. The support plates 57, the activated carbon filter plate 42, the high-efficiency filter mesh two 43, and the porous fiber block 44 are distributed at intervals. The bottom of the ultrasonic transducer 58 is in contact with the tops of the activated carbon filter plate 42, the high-efficiency filter mesh two 43, and the porous fiber block 44. The upper support plate 57 is located below the lower connecting pipe 49.

[0063] Further, after the flue gas enters the interior of the desulfurization and dust removal main body 2 through the smoke inlet pipe 10, the desulfurization treatment is first completed through an oxidation reaction. Then, the activated carbon filter plate 42 adsorbs the dust in the passing flue gas. The flue gas after the primary adsorption and filtration passes through three groups of high-efficiency filter meshes II 43 with different pore sizes for secondary filtration, and then the porous fiber block 44 conducts a third filtration on the dust in the flue gas. Finally, after the fourth dust adsorption by the anode plate 48, it is heated and discharged into the interior of the connection box I 29. During the treatment of the flue gas, the water pump 51 is regularly started as needed. Then, the water in the water storage tank 50 can be pumped out through the water extraction pipe 53, transported into the interior of the booster pump 52 through the water delivery hose 54, and finally transported into the interior of the connection pipe 49 through the water delivery steel pipe 55, so that the spray nozzles 46 and atomizing nozzles 47 on the surfaces of the two groups of water storage pipes 45 can spray water on the surfaces of the anode plate 48 and the porous fiber block 44. Then, the dust adhered to the surfaces of the anode plate 48 and the porous fiber block 44 can be cleaned. At the same time, the ultrasonic transducer 58 at the bottom of the support plate 57 is started, and then the dust adhered to the surfaces of the activated carbon filter plate 42, the high-efficiency filter mesh II 43 and the porous fiber block 44 can be shaken off, which can guarantee the treatment quality of the subsequent flue gas to a certain extent and is also beneficial to improving the practicability of the desulfurization and dust removal main body 2.

[0064] Further, the usage method of this desulfurization and dust remover is as follows:

[0065] S1. Before using this desulfurization and dust remover, first insert the first filter plate 20 into the top of the air injection pipe 14 as needed, and fix the filter mesh I 19 in the storage box 6 through the fitting of the storage plate I 17 and the baffle 16. Then, pour an appropriate amount of prepared limestone slurry into the storage box 6. Through the setting of the one-way valve I 15, the limestone slurry can be prevented from flowing into the interior of the connection box 11;

[0066] S2. When using the desulfurization and dust removal main body 2, first pass the flue gas into the desulfurization and dust removal main body 2 through the smoke inlet pipe 10, and open the electronic valve I 13, so that the air inlet pipe 12 can transport air into the connection box 11 and spray it out through the air injection pipe 14, so that the input air can gush out in the limestone slurry. At the same time, the introduced flue gas will gush out from the limestone slurry;

[0067] S3. After the flue gas undergoes desulfurization treatment, it will successively pass through the activated carbon filter plate 42, three groups of high-efficiency filter meshes II 43 with different pore sizes and the porous fiber block 44 to continue secondary filtration, thereby reducing the proportion of dust and other harmful gases in the flue gas. Then, the fine particles are adsorbed by the anode plate 48;

[0068] S4. During the desulfurization and dust removal process, regularly start the water pump 51 so that the water suction pipe 53 can pump out the water in the water storage tank 50, and convey the water into the internal part of the booster pump 52 through the water delivery hose 54 for boosting pressure. Finally, convey the water into the internal part of the connecting pipe 49 through the water delivery steel pipe 55, and finally spray the water on the surfaces of the anode plate 48 and the high-efficiency filter screen II 43 through the spray nozzles 46 and atomizing nozzles 47 on the surfaces of the two groups of water storage pipes 45.

[0069] In step S1, the following steps are further included:

[0070] S11. Then insert the storage frame 6 into the inside of the notch 1 3 so that the insertion rod 9 can be engaged with the insertion hole 4, and make the sealing gasket 7 fit with the surface of the desulfurization dust collector main body 2 through the engagement of the insertion block 8 and the insertion slot 5, so that the sealing gasket 7 can seal the connection between the notch 1 3 and the storage frame 6, and externally connect the air compressor to the air inlet pipe 12.

[0071] In step S2, the following steps are further included:

[0072] S21. During this process, sulfur dioxide in the flue gas will contact calcium carbonate in the limestone slurry and oxygen in the ejected air to produce an oxidation reaction, generating calcium sulfate. When the calcium sulfate reaches a certain saturation degree, it will crystallize to form gypsum dihydrate. Through the settings of the first net plate 19 and the first filter screen plate 20, the probability of blockage of the spray pipe 14 can be reduced to a certain extent.

[0073] In step S3, the following steps are further included:

[0074] S31. During this process, regularly start the electric heating plate 28, and then start the purge blower 22 so that the first delivery pipe 23 can convey air into the inside of the heating box 24, and after passing through the electric heating plate 28, blow the heat to the porous ceramic regenerator 27, and finally convey it into the inside of the desulfurization dust collector main body 2 through the second delivery pipe 25, so that the fed heating gas can be mixed with the filtered flue gas, and be discharged into the inside of the first connection box 29 through the slot holes, and be conveyed into the inside of the second connection box 31 through the smoke delivery pipe 30.

[0075] When using the heating box 24 in step S31, the following steps are further included:

[0076] S311. The purge blower 22 blows hot air into the inside of the desulfurization dust collector main body 2 through the porous ceramic regenerator 27, so that the porous ceramic regenerator 27 can store heat, and when the electric heating plate 28 is turned off, still can blow hot air into the desulfurization dust collector main body 2 through the purge blower 22, thus playing a role in energy conservation to a certain extent and reducing resource consumption.

[0077] In the process of the purified flue gas moving in the smoke delivery pipe 30, the gas detector 39 on the storage net frame 38 is used to analyze and detect whether the purified flue gas meets the emission standards. If the detection is qualified, the second electronic valve is opened, and at this time, the flue gas will be discharged through the exhaust pipe 33. Otherwise, the exhaust fan in the storage box 34 is started, and then the flue gas in the connection box two 31 can be extracted through the first extraction pipe 35, and the flue gas is pumped into the interior of the flue gas purification box 37 through the second extraction pipe 36, and the sulfur dioxide and dust in the flue gas are filtered through the molecular sieve 40 and the first high-efficiency filter screen 41, which can improve the efficiency of flue gas purification treatment to a certain extent;

[0078] In step S4, the following steps are further included:

[0079] S41. At the same time, the ultrasonic transducer 58 at the bottom of the support plate 57 is started, and then the activated carbon filter plate 42, the second high-efficiency filter screen 43 and the porous fiber block 44 can be driven to vibrate by the ultrasonic transducer 58, so that the dust adhered to the surfaces of the activated carbon filter plate 42, the second high-efficiency filter screen 43 and the porous fiber block 44 can be shaken off, improving the cleaning efficiency, and thus improving the efficiency and quality of subsequent flue gas purification to a certain extent.

[0080] Working principle: When using the desulfurization and dust removal device main body 2, first, flue gas is introduced into the desulfurization and dust removal device main body 2 through the smoke inlet pipe 10, and the first electronic valve 13 is opened, so that the air inlet pipe 12 can transport air into the connection box 11. Then, the sulfur dioxide in the flue gas entering the desulfurization and dust removal device main body 2 will contact with calcium carbonate in the limestone slurry and oxygen in the ejected air to generate an oxidation reaction, generating calcium sulfate. Then, the flue gas after desulfurization treatment will successively pass through the activated carbon filter plate 42, the second high-efficiency filter screen 43 and the porous fiber block 44 for secondary filtration, and the fine particles are adsorbed by the anode plate 48. During this process, the electric heating plate 28 is started regularly, and the purging fan 22 is started, so that the first delivery pipe 23 can transport air into the interior of the heating box 24, and under the action of the purging fan 22, the heat generated by the electric heating plate 28 is blown into the porous ceramic regenerator 27, and finally transported into the desulfurization and dust removal device main body 2 through the second delivery pipe 25, so that the introduced heating gas can be mixed with the filtered flue gas and discharged into the interior of the connection box one 29 through the slot holes;

[0081] Then the flue gas will move in the smoke delivery pipe 30, and the gas detector 39 is used to analyze and detect whether the flue gas meets the emission standards. If the detection is qualified, the second electronic valve is opened, and the flue gas will be discharged through the exhaust pipe 33. Otherwise, the exhaust fan is started, and then the flue gas can be pumped into the interior of the flue gas purification box 37 and discharged after being filtered by the molecular sieve 40 and the first high-efficiency filter screen 41;

[0082] Then, the water pump 51 is regularly started, so that the water suction pipe 53 can send the water in the water storage tank 50 into the interior of the booster pump 52, and the pressurized water is transported into the interior of the connecting pipe 49 through the water delivery steel pipe 55. Finally, the water is sprayed on the surfaces of the anode plate 48 and the high-efficiency filter screen II 43 through the spray nozzles 46 and the atomizing nozzles 47, and is matched with the ultrasonic transducer 58 to clean the dust adhering to the surfaces of the activated carbon filter screen plate 42, the high-efficiency filter screen II 43 and the porous fiber block 44, which can provide convenience for the subsequent flue gas filtration work to a certain extent.

Before using the desulfurization dust collector, first insert the first filter plate (20) into the top of the air injection pipe (14) as needed, and fix the first filter plate (19) in the storage box (6) by the fitting of the first storage plate (17) and the baffle plate (16). Then pour an appropriate amount of prepared limestone slurry into the storage box (6). Through the setting of the first one-way valve (15), the limestone slurry can be prevented from flowing into the interior of the connection box (11). S2. When using the desulfurization dust collector main body (2), first introduce flue gas into the desulfurization dust collector main body (2) through the flue gas inlet pipe (10), and open the first electronic valve (13) so that the air inlet pipe (12) can transport air into the connection box (11) and spray it out through the air injection pipe (14), so that the input air can gush out in the limestone slurry. At the same time, the introduced flue gas will gush out from the limestone slurry. S3. After the flue gas undergoes desulfurization treatment, it will successively pass through the activated carbon filter plate (42), three groups of high-efficiency filter screens II (43) with different pore sizes, and the porous fiber block (44) to continue secondary filtration, thereby reducing the proportion of dust and other harmful gases in the flue gas. Then, the fine particles are adsorbed by the anode plate (48). S4. During the desulfurization and dust removal process, regularly start the water pump (51) so that the water extraction pipe (53) can extract the water in the water storage tank (50), and transport the water into the internal part of the booster pump (52) through the water delivery hose (54) for pressurization. Finally, the water is transported into the internal part of the connection pipe (49) through the water delivery steel pipe (55), and finally the water is sprayed on the surfaces of the anode plate (48) and the high-efficiency filter screen II (43) through the spray nozzles (46) and the atomizing nozzles (47) on the surfaces of the two groups of water storage pipes (45).

10. The usage method of a desulfurization dust collector with good energy-saving effect according to claim 9, characterized in that, In the step S1, the following steps are further included: S11. Then insert the storage box (6) into the first notch (3) so that the insertion rod (9) can be fitted with the insertion hole (4), and the sealing gasket (7) is made to fit with the surface of the desulfurization dust collector main body (2) by the fitting of the insertion block (8) and the slot (5), so that the sealing gasket (7) can seal the connection between the first notch (3) and the storage box (6), and connect the air inlet pipe (12) to an air compressor. In the step S2, the following steps are further included: S21. During this process, sulfur dioxide in the flue gas will contact calcium carbonate in the limestone slurry and oxygen in the sprayed air to produce an oxidation reaction, generating calcium sulfate. When the calcium sulfate reaches a certain saturation, it will crystallize to form gypsum dihydrate. Through the setting of the first filter plate (19) and the first filter screen (20), the probability of blockage of the air injection pipe (14) can be reduced to a certain extent. In the step S3, the following steps are further included: S31. During this process, the electric heating plate (28) is started regularly, and then the purging blower (22) is started, so that the first conveying pipe (23) can convey air into the interior of the heating box (24), and after passing through the electric heating plate (28), the heat is blown to the porous ceramic regenerator (27), and finally conveyed into the interior of the desulfurization and dust removal main body (2) through the second conveying pipe (25), so that the fed heating gas can be mixed with the filtered flue gas, and discharged into the interior of the first connection box (29) through the slot holes, and conveyed into the interior of the second connection box (31) through the smoke conveying pipe (30); When using the heating box (24) in step S31, the following steps are further included: S311. The purging blower (22) blows hot air into the interior of the desulfurization and dust removal main body (2) through the porous ceramic regenerator (27), so that the porous ceramic regenerator (27) can store heat, and when the electric heating plate (28) is turned off, hot air can still be blown into the desulfurization and dust removal main body (2) through the purging blower (22), so as to play an energy-saving role to a certain extent and reduce resource consumption; S32. During the movement of the purified flue gas in the smoke conveying pipe (30), the gas detector (39) on the storage net frame (38) is used to analyze and detect whether the purified flue gas meets the emission standard. If the detection is qualified, the second electronic valve opens, and at this time the flue gas will be discharged through the smoke exhaust pipe (33). Otherwise, the exhaust fan in the storage box (34) is started, and then the flue gas in the second connection box (31) can be extracted through the first extraction pipe (35), and the flue gas is pumped into the interior of the flue gas purification box (37) through the second extraction pipe (36), and the sulfur dioxide and dust in the flue gas are filtered through the molecular sieve (40) and the first high-efficiency filter screen (41), which can improve the efficiency of flue gas purification treatment to a certain extent; In step S4, the following steps are further included: S41. At the same time, the ultrasonic transducer (58) at the bottom of the support plate (57) is started, and then the ultrasonic transducer (58) can drive the activated carbon filter plate (42), the second high-efficiency filter screen (43) and the porous fiber block (44) to vibrate, so that the dust adhered to the surfaces of the activated carbon filter plate (42), the second high-efficiency filter screen (43) and the porous fiber block (44) can be shaken off, improving the cleaning efficiency, and further improving the efficiency and quality of subsequent flue gas purification to a certain extent.
