Description

Technical Field

[0001] The utility model relates to the technical field of smoke treatment, in particular to a desulfurization device containing a turbulator. Background Art

[0002] The desulfurization device with turbulator is an environmental protection equipment that uses the principle of forced turbulence to improve the desulfurization efficiency. In this device, the turbulator is a key component and equipment, and its main function is to promote the full mixing between the desulfurizer and the sulfur-containing gas to improve the mass transfer efficiency, shorten the reaction time, and thus improve the desulfurization efficiency.

[0003] A desulfurization device containing a turbulator is disclosed in Chinese patent publication No. CN214075948U. The desulfurization device containing a turbulator can increase the contact area and contact time between the slurry and the exhaust gas through the turbulator, increase gas-liquid mass transfer, and improve the desulfurization effect.

[0004] However, compared with the existing technologies in related fields, the design of the turbulator determines the turbulence intensity in the tower. Appropriate turbulence can increase the gas-liquid contact area, promote the mixing of desulfurizer and flue gas, and improve the mass transfer efficiency. If the turbulence intensity is too low, the mixing is insufficient and the desulfurization efficiency will decrease; if the turbulence intensity is too high, it may cause excessive fragmentation of desulfurizer droplets, increase energy consumption, and may cause desulfurizer loss, high flue gas system resistance and high power consumption, and even the system resistance is too large, making it difficult to select the induced draft fan.

[0025] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0026] like Figures 1 to 7 As shown, a desulfurization device containing a turbulator comprises a desulfurization tower 1, wherein a plurality of turbulence mechanisms 2 are arranged inside the desulfurization tower 1, a demister 101 is arranged near the top of the desulfurization tower 1, the turbulence mechanism 2 comprises a bracket 201, a plurality of turbulence separation tubes 202 are fixedly installed inside the bracket 201, and a spray mechanism 3 is arranged above the plurality of turbulence mechanisms 2 on the desulfurization tower 1; a cyclone 4, a venturi confluence assembly 5, a packing layer 6 and a grid baffle 7 are arranged inside the turbulence separation tubes 202 in sequence from bottom to top, and the spray mechanism 3 is used to distribute the desulfurizer inside the plurality of turbulence separation tubes 202; the venturi confluence assembly 5 comprises an upper tube 501 and a lower tube 502, a hose 503 is fixedly arranged between the upper tube 501 and the lower tube 502, A flow detection component 8 is axially slidably provided inside the lower tube 502, and a plurality of adjustment components 9 for controlling the deformation of the hose 503 are provided on the outer surface of the lower tube 502. The flow detection component 8 is connected with the adjustment component 9 through the transmission component 10. When the pressure of the rising air flow is small, the flow detection component 8 slides axially downward, and then the adjustment component 9 is controlled by the transmission component 10 to squeeze the hose 503, so that the inner diameter of the middle position of the hose 503 becomes smaller, thereby allowing the gas to gather and accelerate the flow. When the rising gas pressure is large, the flow detection component 8 slides axially upward, and then the adjustment component 9 is controlled by the transmission component 10 to gradually loosen the constraint on the hose 503, so that the inner diameter of the middle position of the hose 503 becomes larger, thereby ensuring the flow speed of the gas. Figure 2 As shown, the spray mechanism 3 includes a water supply pipe 301, and the water supply pipe 301 is located at the center of the plurality of turbulent separation pipes 202, and a spray pipe 302 is fixedly provided. An air outlet pipe is provided at the top of the desulfurization tower 1, and an air inlet pipe is provided near the bottom of the outer surface of the desulfurization tower 1, as shown in FIG. Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, during operation, the flue gas enters the desulfurization tower 1 through the air inlet pipe of the desulfurization tower 1, and first sprays the desulfurizer into the multiple turbulent separation tubes 202 through the spray mechanism 3, and then the flue gas rises and enters the multiple turbulent separation tubes 202 of the lowest turbulent mechanism 2. When the flue gas enters the turbulent separation tube 202, the cyclone 4 causes the flue gas to swirl, and the flue gas passing through the cyclone 4 will enter the Venturi confluence component 5. Turbulence will be formed when the flue gas passes through the Venturi confluence component 5, so that the flue gas passing through the turbulent flow can be fully mixed with the desulfurizer sprayed by the spray mechanism 3. At this time, the flue gas will gradually pass through the packing layer 6 and the grid baffle 7, and then enter the other turbulent mechanisms 2, which effectively promotes the mixing of the desulfurizer and the flue gas and improves the mass transfer efficiency. After that, the gas after desulfurization will separate the moisture inside through the demister 101, and then be discharged through the outlet pipe of the desulfurization tower 1.

[0027] like Figures 4 to 7 As shown, the flow detection component 8 includes an annular member 801 slidably arranged inside the lower tube 502, and a chamfered surface 802 is provided at the bottom of the annular member 801, and the inclined surface faces the center of the lower tube 502; the adjustment component 9 includes an adjustment block 901 fixedly connected to the hose 503, and a support rod 902 is fixedly provided on the side of the adjustment block 901 away from the hose 503; the transmission component 10 includes a fixed frame 1001 fixedly mounted on the outer surface of the lower tube 502, and a movable rod 1002 is rotatably arranged inside the fixed frame 1001, and the end of the movable rod 1002 away from the fixed frame 1001 is hinged to the end of the support rod 902, and the end of the movable rod 1002 close to the fixed frame 1001 is fixedly provided with a gear 1003, and the outer surface of the gear 1003 is meshed with a tooth The rack 1004 is arranged between the gear 1003 and the lower tube 502, and the rack 1004 is connected to the ring member 801 through the connecting block 1005; the lower tube 502 is provided with movable grooves 5021 at positions corresponding to the plurality of connecting blocks 1005. When the ring member 801 drives the rack 1004 to slide downward through the connecting block 1005, the gear 1003 is meshed with the rack 1004, so that the gear 1003 controls the movable rod 1002 to swing toward one side of the lower tube 502. When the ring member 801 drives the rack 1004 to slide upward through the connecting block 1005, the gear 1003 is meshed with the rack 1004, so that the gear 1003 drives the movable rod 1002 to swing toward the side away from the lower tube 502.

[0028] like Figures 4 to 7As shown in the figure, when the rising gas pressure is large, the annular member 801 slides axially upward, and then the annular member 801 drives the rack 1004 to slide upward through the connecting block 1005. The rack 1004 is meshed with the gear 1003, so that the gear 1003 drives the movable rod 1002 to swing to the side away from the lower tube 502. At this time, the support rod 902 gradually loosens the constraint on the hose 503 through the adjusting block 901, so that the inner diameter of the middle position of the hose 503 becomes larger, thereby ensuring the flow of gas. When the pressure of the rising air flow is small, the annular member 801 slides axially downward, and then the annular member 801 drives the rack 1004 to slide downward through the connecting block 1005. The rack 1004 is meshed with the gear 1003, so that the gear 1003 drives the movable rod 1002 to swing to one side of the lower tube 502. At this time, the support rod 902 gradually squeezes the hose 503 through the adjusting block 901, so that the inner diameter of the middle part of the hose 503 becomes smaller, thereby allowing the gas to gather and accelerate the flow.

[0029] To sum up: the inner diameter of the middle part of the hose 503 can be adaptively adjusted according to the rising pressure of the gas to ensure the flow velocity and turbulence intensity of the gas, so that the gas can be fully mixed with the desulfurizer, improve the mass transfer efficiency, and avoid the loss of desulfurizer, high resistance of the flue gas system and high power consumption.

[0030] The desulfurization tower 1, the demister 101, the spray mechanism 3, the cyclone 4, the packing layer 6 and the grid baffle 7 described in the present application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0031] The working process is as follows:

[0032] S1. When working, Figures 1 to 3 As shown, the flue gas enters the desulfurization tower 1 through the air inlet pipe of the desulfurization tower 1, and first sprays the desulfurizer into the multiple turbulent separation tubes 202 through the spray mechanism 3, and then the flue gas rises and enters the multiple turbulent separation tubes 202 of the lowest turbulent mechanism 2;

[0033] S2, such as Figure 2 , Figure 3 and Figure 5 As shown, when the flue gas enters the turbulent separation tube 202, the cyclone 4 causes the flue gas to swirl, and the flue gas passing through the cyclone 4 enters the venturi converging assembly 5;

[0034] S3, such as Figures 4 to 7As shown, when the rising gas pressure is large, the annular member 801 slides axially upward, and then the annular member 801 drives the rack 1004 to slide upward through the connecting block 1005. The rack 1004 is meshed with the gear 1003, so that the gear 1003 drives the movable rod 1002 to swing to the side away from the lower tube 502. At this time, the support rod 902 gradually loosens the constraint on the hose 503 through the adjusting block 901, so that the inner diameter of the middle position of the hose 503 becomes larger, thereby ensuring the flow speed of the gas;

[0035] S4, such as Figures 4 to 7 As shown, when the pressure of the rising air flow is small, the annular member 801 slides axially downward, and then the annular member 801 drives the rack 1004 to slide downward through the connecting block 1005. The rack 1004 is meshed with the gear 1003, so that the gear 1003 drives the movable rod 1002 to swing to one side of the lower tube 502. At this time, the support rod 902 gradually squeezes the hose 503 through the adjusting block 901, so that the inner diameter of the middle position of the hose 503 becomes smaller, so that the gas gathers and accelerates the flow;

[0036] S5, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, when the flue gas passes through the Venturi converging assembly 5, turbulence will be formed, so that the flue gas after turbulence can be fully mixed with the desulfurizer sprayed by the spray mechanism 3. At this time, the flue gas will gradually pass through the packing layer 6 and the grid baffle 7, and then enter the other turbulent flow mechanisms 2, which effectively promotes the mixing of the desulfurizer and the flue gas and improves the mass transfer efficiency. After that, the gas after desulfurization will separate the moisture inside through the demister 101 and then be discharged through the outlet pipe of the desulfurization tower 1;

[0037] S6. In summary, the inner diameter of the middle part of the hose 503 can be adaptively adjusted according to the rising pressure of the gas to ensure the flow velocity and turbulence intensity of the gas, so that the gas can be fully mixed with the desulfurizer, improve the mass transfer efficiency, and avoid the problems of desulfurizer loss, high flue gas system resistance and high power consumption.
