[0014] A method for using a skid-mounted modular blended super activated carbon desulfurization acid-making system, the method comprising the following steps:

[0015] When multiple desulfurization units are disassembled, a pry bar is inserted into the top groove on the card plate. During the squeezing process of the pry bar, the card plate can be driven to slide in the operating hole in the baffle. The card plate drives the slide plate to slide in the slideway and squeezes the spring until the card plate is separated from the operating hole. Then, the card plate is pushed obliquely by the pry bar, and the end of the pry bar is limited by the top groove so that the pry bar will not slip off the card plate. The card plate pushes the column and the desulfurization unit to rotate through the slide plate until the column is separated from the baffle. The locking state of the desulfurization unit can be released. The lower desulfurization unit can be lifted by hoisting equipment or lifting equipment to separate the connecting tube at the bottom of the desulfurization unit from the wind tube. The desulfurization unit can be removed. The same operation can be performed when disassembling other desulfurization units.

[0016] When assembling the desulfurization unit, the current desulfurization unit is mounted on the lower desulfurization unit so that the support frame on the lower desulfurization unit overlaps with the bottom of the upper desulfurization unit, and the connecting tube is inserted into the inside of the wind tube, and the baffle ring outside the connecting tube overlaps with the top of the wind tube. At this time, multiple columns at the bottom of the upper desulfurization unit overlap with the guide wheel on the lower desulfurization unit. By pushing the upper desulfurization unit to rotate, the desulfurization unit drives the skid-mounted assembly to deflect through the columns. The card plate in the skid-mounted assembly will contact the baffle plate in the side baffle assembly during the rotation process. Because the side of the card plate close to the side baffle assembly is provided with an inclined groove, the inclined groove will make the card plate approach the column after being pressed until the card plate fits the inner wall of the baffle plate;

[0017] When the column contacts the limit stop bar during rotation, it stops rotating, which plays a role in limiting the column and the card plate. At this time, the position of the card plate corresponds to the operating hole on the baffle plate. The slide plate is squeezed by the elastic force of the two springs in the slideway, so that the slide plate drives the card plate to be stuck in the operating hole. The position of the column can be locked by limiting the card plate through the operating hole, thereby completing the installation of the desulfurization unit. The same operation can be performed when installing other desulfurization units, thereby achieving the purpose of modular assembly of multiple desulfurization units;

[0018] During the desulfurization and acid production work, the sulfur-containing flue gas enters the lowest desulfurization unit through the air inlet base, and the flue gas will pass through the super activated carbon desulfurization packing layer in the desulfurization unit, so that the sulfur dioxide in the flue gas is absorbed by the super activated carbon desulfurization packing layer, and sulfur trioxide is generated under the catalytic oxidation of the super activated carbon desulfurization packing layer and oxygen in the flue gas, and then reacts with water vapor from the flue gas to generate sulfuric acid, which is adsorbed on the inner surface of the super activated carbon desulfurization packing layer. As the desulfurization reaction continues, the amount of sulfuric acid accumulated in the super activated carbon desulfurization packing layer continues to increase, and the active sites for sulfur dioxide adsorption and catalytic conversion are gradually occupied, the desulfurization performance continues to decrease, and the super activated carbon desulfurization packing layer is regenerated. After cutting off the flue gas from the air inlet base, the flue gas will not enter the desulfurization unit, the return valve pipe is opened, the spray connecting valve pipe is connected, and the super activated carbon desulfurization packing layer is treated with a graded water washing regeneration process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, when assembling the desulfurization unit, the current desulfurization unit is mounted on the lower desulfurization unit, so that the support frame on the lower desulfurization unit overlaps with the bottom of the upper desulfurization unit, and the connecting tube is plugged into the wind tube. By pushing the upper desulfurization unit to rotate, the desulfurization unit drives the skid-mounted assembly to deflect through the column. The card plate in the skid-mounted assembly will contact the baffle in the side baffle assembly during the rotation process. Because the side of the card plate close to the side baffle assembly is provided with an inclined groove, the inclined groove will make the card plate approach the column after being pressed until the card plate fits with the inner wall of the baffle. During the rotation of the column, the card plate and the limit When the baffle comes into contact, it stops rotating, which serves to limit the column and the card plate. At this time, the position of the card plate corresponds to the position of the operating hole on the baffle plate. The elastic force of the two springs in the slideway squeezes the slide plate, so that the slide plate drives the card plate to be inserted into the operating hole. The position of the column can be locked by limiting the card plate through the operating hole, thereby completing the installation of the desulfurization unit. The same operation can be performed when installing other desulfurization units. Therefore, the purpose of modular assembly of multiple desulfurization units can be achieved, and the use of traditional integrated desulfurization towers for desulfurization and acid production is abandoned, so as to facilitate the stacking and maintenance of desulfurization units.

[0021] 2. In the present invention, a pry bar is inserted into the top groove on the card plate, and the card plate can be driven to slide in the operating hole in the baffle during the squeezing of the pry bar. The card plate drives the slide plate to slide in the slideway and squeezes the spring until the card plate is separated from the operating hole. Secondly, the card plate is pushed obliquely by the pry bar, and the end of the pry bar is limited by the top groove to prevent the pry bar from slipping off the card plate. The card plate pushes the column and the desulfurization unit to rotate through the slide plate until the column is separated from the baffle, and the locking state of the desulfurization unit can be released. The desulfurization unit can be lifted by a hoisting device or a lifting device to separate the connecting tube at the bottom of the desulfurization unit from the wind tube, and the desulfurization unit can be removed, which is convenient for independent maintenance or replacement of the desulfurization unit, reducing the use cost, alleviating the workload and improving the convenience of operation.

A wind tube 4 is installed on the top of the desulfurization unit 1, and a connecting tube 5 is installed on the bottom of the desulfurization unit 1. The connecting tube 5 and the wind tube 4 are mutually clamped. A baffle ring 6 is fixedly connected to the outside of the connecting tube 5, and the bottom of the baffle ring 6 overlaps with the top of the wind tube 4. Because the connecting tube 5 will be inserted into the inside of the wind tube 4, the baffle ring 6 outside the connecting tube 5 overlaps with the top of the wind tube 4, which plays a role in limiting the connecting tube 5 and the wind tube 4. Because a sealing gasket is provided at the bottom of the baffle 901, it plays a role in sealing and connecting the connecting tube 5 and the wind tube 4;

[0032] A support frame 7 is installed on the desulfurization unit 1, the top of the support frame 7 overlaps the bottom of the desulfurization unit 1, the support frame 7 is annular in design, and a number of through holes 8 are equidistantly provided outside the support frame 7. The arrangement of the through holes 8 facilitates operation on the top of the desulfurization unit 1, and the support frame 7 supports the desulfurization unit 1 above, thereby reducing the risk of operation;

[0033] A plurality of side baffle assemblies 9 are provided on the outside of the support frame 7. The bottom of the side baffle assemblies 9 is fixed on the desulfurization unit 1. The side baffle assemblies 9 include a baffle 901. An operation hole 903 is provided on the baffle 901. The part of the skid-mounted assembly 12 that passes through the slideway 11 is clamped in the operation hole 903. The inner wall of the baffle 901 is fixedly connected with a limit baffle bar 902. One side of the limit baffle bar 902 overlaps with one side of the column 10. The bottom of the baffle 901 is fixed to the top of the desulfurization unit 1. When the column 10 contacts the limit baffle bar 902 during rotation, the column 10 stops rotating, thereby limiting the column 10 and the clamping plate 122.

[0034] The bottom of the desulfurization unit 1 is equidistantly fixedly connected with a plurality of columns 10, the columns 10 are located inside the side block assembly 9, an annular groove 13 is provided on the desulfurization unit 1, the annular groove 13 is located between the support frame 7 and the side block assembly 9, a plurality of leak holes 14 are provided at the bottom of the annular groove 13, a plurality of guide wheels 15 are installed in the annular groove 13, the bottom of the column 10 overlaps with the guide wheel 15, because the guide wheel 15 is provided, the plurality of columns 10 at the bottom of the upper desulfurization unit 1 overlaps with the guide wheel 15 on the lower desulfurization unit 1, thereby reducing the friction generated when the desulfurization unit 1 rotates, and improving the rotation flexibility of the desulfurization unit 1;

[0035] A slideway 11 is provided in one of the columns 10, and a skid assembly 12 is installed in the slideway 11. The skid assembly 12 includes a slide plate 121, which is slidably connected in the slideway 11. A clamping plate 122 is fixedly connected to one side of the slide plate 121. The clamping plate 122 penetrates the slideway 11 and is clamped in the operating hole 903. Two springs 123 are fixedly connected to one side of the slide plate 121 away from the clamping plate 122. The other end of the spring 123 is fixedly connected to the inner wall of the slideway 11. The slide plate 121 is squeezed by the elastic force of the spring 123, so that the slide plate 121 drives the clamping plate 122 to be clamped in the operating hole 903. The clamping plate 122 is limited by the operating hole 903 to facilitate locking the position of the column 10.

[0036] An inclined groove 125 is provided on one side of the card plate 122, and a top groove 124 is provided on the outer side of the card plate 122. The pry bar pushes the card plate 122 obliquely, and the end of the pry bar is limited by the top groove 124 to prevent the pry bar from slipping off the card plate 122, so that the card plate 122 pushes the column 10 and the desulfurization unit 1 to rotate through the slide plate 121.

[0037] The portion of the skid assembly 12 that passes through the slideway 11 is clamped in the side stop assembly 9 , and the outer wall of the column 10 overlaps the inner wall of the side stop assembly 9 .

[0038] The method of using the skid-mounted modular blended super activated carbon desulfurization acid system includes the following steps:

[0039] When multiple desulfurization units 1 are disassembled, a pry bar is inserted into the top groove 124 on the card plate 122. During the squeezing process of the pry bar, the card plate 122 can be driven to slide in the operating hole 903 in the baffle 901. The card plate 122 drives the slide plate 121 to slide in the slideway 11 and squeezes the spring 123 until the card plate 122 is separated from the operating hole 903. Then, the card plate 122 is pushed obliquely by the pry bar, and the end of the pry bar is limited by the top groove 124, so that the pry bar will not slip off the card plate 122, so that the card plate 122 pushes the column 10 and the desulfurization unit 1 to rotate through the slide plate 121 until the column 10 is separated from the baffle 901, and the locking state of the desulfurization unit 1 can be released. The lower desulfurization unit 1 is lifted by a hoisting device or a lifting device, so that the connecting tube 5 at the bottom of the desulfurization unit 1 is separated from the wind tube 4, and the desulfurization unit 1 can be removed. The same operation can be performed when disassembling other desulfurization units 1;

[0040] When assembling the desulfurization unit 1, the current desulfurization unit 1 is erected on the lower desulfurization unit 1, so that the support frame 7 on the lower desulfurization unit 1 overlaps with the bottom of the upper desulfurization unit 1, and the connecting tube 5 is inserted into the inside of the wind tube 4, and the retaining ring 6 outside the connecting tube 5 overlaps with the top of the wind tube 4. At this time, the multiple columns 10 at the bottom of the upper desulfurization unit 1 overlap with the guide wheel 15 on the lower desulfurization unit 1, and the desulfurization unit 1 is pushed to rotate, so that the desulfurization unit 1 drives the skid-mounted assembly 12 to deflect through the column 10. The card plate 122 in the skid-mounted assembly 12 will contact the baffle 901 in the side baffle assembly 9 during the rotation process. Because the card plate 122 is close to the side of the side baffle assembly 9. The side of the side baffle assembly 9 is provided with an inclined groove 125. After the inclined groove 125 is pressed, the card plate 122 will be close to the column 10 until the card plate 122 fits the inner wall of the baffle 901;

[0041] When the column 10 contacts the limit stop bar 902 during rotation, it stops rotating, which plays a role in limiting the column 10 and the card plate 122. At this time, the card plate 122 corresponds to the position of the operating hole 903 on the baffle 901. The slide plate 121 is squeezed by the elastic force of the two springs 123 in the slideway 11, so that the slide plate 121 drives the card plate 122 to be stuck in the operating hole 903. The position of the column 10 can be locked by limiting the card plate 122 through the operating hole 903, thereby completing the installation of the desulfurization unit 1. The same operation can be performed when installing other desulfurization units 1, thereby achieving the purpose of modular assembly of multiple desulfurization units 1;

[0042] During the desulfurization and acid production operation, the sulfur-containing flue gas enters the bottom desulfurization unit 1 through the air inlet base 2, and the flue gas passes through the super activated carbon desulfurization packing layer 3 in the desulfurization unit 1, so that the sulfur dioxide in the flue gas is absorbed by the super activated carbon desulfurization packing layer 3, and sulfur trioxide is generated under the catalytic oxidation of the super activated carbon desulfurization packing layer 3 and the oxygen in the flue gas, and then reacts with the water vapor from the flue gas to generate sulfuric acid, which is adsorbed on the inner surface of the super activated carbon desulfurization packing layer 3. As the desulfurization reaction continues, the amount of sulfuric acid accumulated in the super activated carbon desulfurization packing layer 3 continues to increase, the active sites for sulfur dioxide adsorption and catalytic conversion are gradually occupied, the desulfurization performance continues to decrease, and the super activated carbon desulfurization packing layer 3 is regenerated. After the flue gas of the air inlet base 2 is cut off, the flue gas will not enter the desulfurization unit 1, the return liquid valve pipe 18 is opened, the spray connecting valve pipe 17 is connected, and the super activated carbon desulfurization packing layer 3 is treated with a graded water washing regeneration process.

The upper part of the desulfurization unit (1) is limited so that the pry bar will not slip off the card plate (122), and the card plate (122) pushes the column (10) and the desulfurization unit (1) to rotate through the slide plate (121) until the column (10) is separated from the baffle plate (901), and the locking state of the desulfurization unit (1) can be released. The lower desulfurization unit (1) is lifted by a hoisting device or a lifting device, and the connecting tube (5) at the bottom of the desulfurization unit (1) is separated from the wind tube (4), and the desulfurization unit (1) can be removed. The same operation can be performed when removing other desulfurization units (1); When assembling the desulfurization unit (1), the current desulfurization unit (1) is mounted on the lower desulfurization unit (1), so that the support frame (7) on the lower desulfurization unit (1) overlaps with the bottom of the upper desulfurization unit (1), and at the same time, the connecting tube (5) is inserted into the inside of the wind tube (4), and the retaining ring (6) outside the connecting tube (5) overlaps with the top of the wind tube (4). At this time, the multiple columns (10) at the bottom of the upper desulfurization unit (1) overlap with the guide wheel (15) on the lower desulfurization unit (1), and by pushing the upper desulfurization unit (1) rotating, so that the desulfurization unit (1) drives the skid-mounted assembly (12) to deflect through the column (10), and the clamping plate (122) in the skid-mounted assembly (12) will contact the baffle (901) in the side baffle assembly (9) during the rotation process. Because the side of the clamping plate (122) close to the side baffle assembly (9) is provided with an inclined groove (125), the inclined groove (125) will be pressed to make the clamping plate (122) approach the column (10) until the clamping plate (122) and the inner wall of the baffle (901) are in contact; When the column (10) contacts the limit stop bar (902) during rotation, it stops rotating, thus limiting the column (10) and the clamping plate (122). At this time, the clamping plate (122) corresponds to the position of the operating hole (903) on the baffle (901). The slide plate (121) is squeezed by the elastic force of the two springs (123) in the slideway (11), so that the slide plate (121) drives the clamping plate (122) to be clamped into the operating hole (903). The clamping plate (122) is limited through the operating hole (903) to lock the position of the column (10), thereby completing the installation of the desulfurization unit (1). The same operation can be performed when installing other desulfurization units (1), thereby achieving the purpose of modular assembly of multiple desulfurization units (1); When the desulfurization and acid production is in progress, the sulfur-containing flue gas enters the bottom desulfurization unit (1) through the air inlet base (2), and the flue gas passes through the super activated carbon desulfurization packing layer (3) in the desulfurization unit (1), so that the sulfur dioxide in the flue gas is absorbed by the super activated carbon desulfurization packing layer (3), and sulfur trioxide is generated under the catalytic oxidation of the super activated carbon desulfurization packing layer (3) and oxygen in the flue gas, and then reacts with water vapor from the flue gas to generate sulfuric acid, which is adsorbed on the inner surface of the super activated carbon desulfurization packing layer (3). As the sulfur reaction continues, the amount of sulfuric acid accumulated in the super activated carbon desulfurization packing layer (3) continues to increase, the active sites for sulfur dioxide adsorption and catalytic conversion are gradually occupied, the desulfurization performance continues to decrease, and the super activated carbon desulfurization packing layer (3) is regenerated. After the flue gas of the air intake base (2) is cut off, the flue gas will not enter the desulfurization unit (1), the return liquid valve pipe (18) is opened, the spray connecting valve pipe (17) is connected, and the super activated carbon desulfurization packing layer (3) is treated by a graded water washing regeneration process.
