Description

Technical Field

[0001] This invention relates to the field of boiler combustion exhaust gas desulfurization technology, and in particular to a boiler desulfurization device. Background Technology

[0002] A common boiler desulfurization device is the limestone-gypsum desulfurization device, also known as a wet desulfurization device. This device removes SO2 from the flue gas by injecting limestone slurry into the flue gas, causing SO2 in the flue gas to react with CaCO3 in the limestone to form gypsum (CaSO4·2H2O).

[0003] However, during use, the effluent device of wet desulfurization is still in a state of large water flow when there is less waste gas, making it difficult to limit the water output according to the amount of waste gas, which will result in waste of water resources. In addition, the water flow is generally in a relatively fixed direction, resulting in low desulfurization efficiency. Summary of the Invention

It includes a housing component 100, including a housing assembly 101, which is a container for containing waste gas for desulfurization, and a water spraying assembly 102 disposed on the housing assembly 101. The water spraying assembly 102 is located at the top inside the housing assembly 101 and is suitable for wet desulfurization.

[0034] The water inlet component 200 includes a water control component 201 disposed on the receiving component 101, the water control component 201 being used to adapt to the corresponding water pressure and to match the corresponding water outlet, and a flow guide component 202 disposed on the water control component 201, the flow guide component 202 being used to guide the water evenly.

[0035] The air intake component 300 includes an air control component 301 disposed on the housing component 101, the air control component 301 being used to control the size of the airflow so as to adapt it to the corresponding air outlet, and a guide component 302 disposed on the air control component 301, the guide component 302 being used to achieve the effect of uniformly distributing the airflow at the outlet.

[0036] The linkage component 400 includes an elastic component 401 disposed on the receiving component 101, the elastic component 401 having the function of progressively increasing elastic force, and a rotating component 402 disposed on the elastic component 401, the rotating component 402 being used to trigger the elastic component 401, the elastic component 401 being able to strengthen its elasticity after the rotating component 402 rotates a certain angle, and also includes a connecting rod assembly 403 disposed on the rotating component 402, the connecting rod assembly 403 having one set of driving and one set of locking, its function being to convert pressure into driving force, combined with the progressively increasing elasticity of the elastic component 401, so that it can achieve a limiting function at a limited angle.

[0037] Specifically, the housing component 101 includes a housing 101a, and a water inlet pipe 101b, an air inlet pipe 101c, a drain pipe 101d, and a tilted box 101e disposed on the housing 101a. The water inlet pipe 101b is fixed to the top of the housing 101a. The air inlet pipe 101c is fixed to the side of the housing 101a and extends into the housing 101a below the water inlet pipe 101b. The drain pipe 101d is fixed to the center of the recess at the bottom of the housing 101a to prevent water pressure from remaining inside the housing 101a during drainage. The tilted box 101e is fixed to the side of the housing 101a opposite to the air inlet pipe 101c. The tilted box 101e is tilted upwards to allow water to enter its interior. It also includes an air outlet pipe 101f disposed on the tilted box 101e. The air outlet pipe 101f is fixed to one end of the outer side of the tilted box 101e.

[0038] Furthermore, the water shower assembly 102 includes a conical perforated plate 102a disposed on the housing 101a, the conical perforated plate 102a rotating at the top of the inner wall of the housing 101a, forming a water storage space on the inner wall at the top of the housing 101a, and a guide plate 102b disposed on the conical perforated plate 102a. Four guide plates 102b are provided, which can be combined to form a cone shape and fixed to the top of the conical perforated plate 102a. The guide plate 102b also includes a pusher... The guide plate 102b has a thrust surface 102c and holes 102d. The top of the guide plate 102b has a thrust surface 102c, which is an inclined surface and slopes counterclockwise from low to high. When the water flows from the bottom surface to the top surface, it has a thrust, which allows the guide plate 102b to drive the conical orifice plate 102a to rotate. The thrust surface 102c also has several holes 102d, which are adapted to and symmetrical with the holes on the conical orifice plate 102a.

[0039] It also includes a limiting tube 102e provided on the conical perforated plate 102a. The conical perforated plate 102a has an opening in the center, and the limiting tube 102e rotates in the opening. The limiting tube 102e is only open at the top. The internal space of the limiting tube 102e can prevent the water control component 201 from detaching from the water inlet pipe. It also includes a groove 102f provided on the limiting tube 102e and a groove 102f provided at the bottom of the limiting tube 102e. It also includes a slider 102g provided on the groove 102f. The slider 102g slides inside the groove 102f, and its bottom is fixed to the connecting rod assembly 403.

[0040] Furthermore, the water control assembly 201 includes a first water plug 201a disposed on the water inlet pipe 101b, the first water plug 201a being located at the inlet of the water inlet pipe 101b to provide a sealing effect, and a connecting rod 201b disposed on the first water plug 201a, the connecting rod 201b being fixed to the top of the first water plug 201a. It also includes a second water plug 201c and a third water plug 201e disposed on the connecting rod 201b, the second water plug 201c being fixed to the middle of the connecting rod 201b, and the third water plug 201e being fixed to the top of the connecting rod 201b. The connecting rod 201b enables the three water plugs to move synchronously. It also includes a second water plug 201c with a first oblique hole 201d. The surface of the second water plug 201c has multiple first oblique holes 201d, which are opened from top to bottom in a counterclockwise direction. It also includes a third water plug 201e with a second oblique hole 201f. The surface of the third water plug 201e has multiple second oblique holes 201f, which have a larger diameter than the first oblique holes 201d and are opened in the same direction as the first oblique holes 201d.

[0041] Furthermore, the flow guiding assembly 202 includes a circular tube 202a, which is positioned at the adjacent locations of the first water plug 201a, the second water plug 201c, and the third water plug 201e, and has water outlet grooves 202b on its surface. The circular tube 202a also includes a flow guiding ring 202c and an inclined plate 202d on its surface. Two flow guiding rings 202c are included, with their outer walls positioned at the bottom of the inner wall of the circular tube 202a, and the inner wall of the circular tube 202a corresponding to the water outlet grooves 202b. b is fixed with inclined plates 202d at adjacent locations. The inclined plates 202d are provided with a force-bearing surface 202e and a flow-guiding surface 202f. The upward counterclockwise inclined surface of the inclined plate 202d is the force-bearing surface 202e, and the downward counterclockwise inclined surface of the inclined plate 202d is the flow-guiding surface 202f. The force-bearing surface 202e can drive the inclined plate 202d after the water flow impacts it. The flow-guiding surface 202f is used to guide the water flow outward so that it can be discharged from the outlet channel 202b. It also has a certain throwing force so that the water has a certain arc after being thrown out.

[0042] The guide ring 202c is connected to the first water plug 201a and the second water plug 201c respectively, and the bottom of the guide ring 202c is fixed to the top of the first water plug 201a and the top of the second water plug 201c respectively.

[0043] In use, firstly, the inlet pipe 101b is connected to a water source. When the water source is turned on, water is introduced into the inlet pipe 101b. After the water enters, it is guided downwards through the second oblique hole 201f on the surface of the third water plug 201e. A portion of the water pressure is squeezed onto the surface of the third water plug 201e, giving it a downward force. Since part of the water is inside the inlet pipe 101b, the downward-flowing water is guided downwards through the first oblique hole 201d of the second water plug 201c and impacts the first water plug 201a, causing its water control component 201 to move downwards. This movement depends on the water pressure. When the second water plug 201c blocks the inlet of the inlet pipe 101b, the first water plug 201a can drive the linkage component 400 to trigger a first-level elastic force and limit. Under higher water pressure, the linkage component 400 can trigger a second-level elastic force and limit function, allowing the water to flow out through the larger second oblique hole 201d at the second water plug 201c. At the inlet of the water inlet pipe 101b, the water flow is guided out from the first inclined hole 201d of the second water plug 201c. The water flow can be guided by the inclination angle of the first inclined hole 201d to the force-bearing surface 202e of the inclined plate 202d, so that the circular pipe 202a connected to the inclined plate 202d can rotate. During the rotation, the guide surface 202f and the guide ring 202c of the inclined plate 202d can drive the water source to be guided, so that the water flow is thrown out from the outlet tank 202b and discharged. The water flow has a certain arc and downward angle, so the water source that is thrown out can exert force evenly on the guide surface 102c of the guide plate 102b, thereby giving the conical orifice plate 102a connected to the guide plate 102b a rotational force. During this process, the water source can be guided downward through the holes 102d and the conical orifice plate 102a. The water source that is guided downward flows out from several holes 102d and has a rotational force, so the gas inside the box 101a can be evenly diluted.

[0044] In summary, it can achieve good mixing of water and exhaust gas under various water pressure conditions, resulting in better dilution.

[0045] Example 2, refer to Figures 1-11This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an air intake component 300 for a boiler desulfurization device, solving the problem of unevenly guiding exhaust gas after it enters the container. It includes an air control assembly 301 comprising a first air plug 301a disposed on an air intake pipe 101c, the first air plug 301a being located at the inlet of the air intake pipe 101c, and a round rod 301b and a conical block 301c disposed on the first air plug 301a. The round rod 301b is fixed to the bottom of the first air plug 301a, and its conical block 301c is fixed to the bottom of the first air plug 301a corresponding to the outer wall of the round rod 301b. It also includes a second air plug 301d and a third air plug 301f disposed on the round rod 301b. The second air plug 301d is fixed to the middle of the round rod 301b, and the third air plug 301f... 1f is fixed to the bottom of the round rod 301b, and also includes a second air plug 301d with an inclined small hole 301e. The surface of the second air plug 301d has multiple inclined small holes 301e, which are opened clockwise from top to bottom. It also includes a third air plug 301f with an inclined large hole 301g. The surface of the third air plug 301f has multiple inclined large holes 301g, which are opened in the same direction as the inclined small holes 301e. It also includes a conical disk 301h on the second air plug 301d. The conical disk 301h is fixed to the bottom of the second air plug 301d. Because the center of the conical disk 301h has a hole, it can guide the airflow to the inclined small hole 301e when not in this stage. The side of the conical disk 301h is inclined, so it has the function of guiding wind force.

[0046] Specifically, the guide assembly 302 includes two connecting rings 302a on the round rod 301b, which are respectively rotatable on the outer wall of the round rod 301b at locations adjacent to the first air plug 301a, the second air plug 301d, and the third air plug 301f. It also includes multiple fan blades 302b on the connecting rings 302a, which are fixed to the outer wall of the connecting rings 302a. The fan blades 302b also include a driving surface 302c and a guiding surface 302d. The bottom inclined surface of the fan blade 302b is the driving surface 302c, and the top inclined surface is the guiding surface 302d. The angle of the driving surface 302c is adapted to the inclination angles of the inclined small hole 301e and the inclined large hole 301g. The guiding surface 302d can cooperate with the conical block 301c or the conical disk 301h to uniformly guide the airflow into the housing 101a.

[0047] The rest of the structure is the same as in Example 1.

[0048] In use, firstly, exhaust gas is introduced into the intake pipe 101c. When the second water plug 201c is at the inlet of the water pipe 101b, its linkage component 400 can drive the intake component 300 to move upward, so that the second air plug 301d is at the inlet of the intake pipe 101c. During this operation, the exhaust gas can be guided upward through the inclined large hole 301g on the surface of the third air plug 301f. Therefore, part of it is currently inside the intake pipe 101c, so the gas can only be guided through the middle of the conical disk 301h to the inclined small hole 301e on the surface of the second air plug 301d. The inclined small hole 301e can guide the airflow to the corresponding fan blade 302b driving surface 302c through its own inclination, so that it drives the fan blade 302b to drive the connecting ring 302a to rotate. When the fan blade 302b rotates, the guiding surface 302d can guide the exhaust gas upward to the conical block 301c, so that the exhaust gas is evenly distributed inside the housing 101a and guided upward, thus fully cooperating with the water spray component 102. When the third water plug 201e is at the inlet of the water pipe 101b, its linkage component 400 can drive the air intake component 300 to move upward again, so that the third air plug 301f is at the inlet of the air pipe 101c. During this operation, the exhaust gas can be directly guided through the inclined large hole 301g to the corresponding fan blade 302b drive surface 302c, so that the fan blade 302b drives the connecting ring 302a to rotate. When the fan blade 302b rotates, the guide surface 302d can guide the exhaust gas upward to the conical disk 301h. This process can also evenly fill the exhaust gas inside the housing 101a, but with an increase in airflow compared to the previous stage.

[0049] In summary, the water inlet component 200 ensures more uniform contact between water and exhaust gas, thereby increasing its desulfurization efficiency.

[0050] Example 3, referring to Figures 1-11This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a linkage component 400 for the boiler desulfurization device, solving the problem of linkage between the water inlet component 200 and the air inlet component 300. It includes the boiler desulfurization device described in the previous embodiment, comprising an elastic component 401 including a fixed seat 401a mounted on a housing 101a. Two fixed seats 401a are fixed to both sides of the inner wall of the housing 101a, located at the center of the opposite end of the first air plug 301a and the slider 102g. The fixed seat 401a is formed by a fixed disc and a fixed rod, with the fixed disc fixed to the housing 101a. A force-bearing shell 401b is mounted on the fixed seat 401a, fixing a coil spring 401c and a delay coil spring 401d. The opening of the force-bearing shell 401b fits against the surface of the fixed disc of the fixed seat 401a, and its inner wall rotates with the fixed rod of the fixed seat 401a. Next, one end of the fixed coil spring 401c is fixed to the outer wall of the fixing rod of the fixing seat 401a, and one end of the fixed coil spring 401c is fixed to the inner wall of the force-bearing shell 401b. One end of the delayed coil spring 401d is fixed to the outer wall of the fixing rod of the fixing seat 401a, corresponding to one side of the fixed coil spring 401c. It also includes a delay groove 401e on the delayed coil spring 401d. The delayed groove 401e is opened on the outer surface of the delayed coil spring 401d. The delayed groove 401e rotates in a ring around the fixing rod of the fixing seat 401a with a 60-degree angle. It also includes a pull block 401f provided on the delayed groove 401e. The pull block 401f is limited inside the delayed groove 401e. One end of the pull block 401f is fixed to the inner wall of the force-bearing shell 401b. The outer ends of the fixed coil spring 401c and the delayed coil spring 401d rotate in a ring around the fixing rod of the fixing seat 401a with a 60-degree angle difference.

[0051] Specifically, the rotating assembly 402 includes a shaft 402a mounted on a force-bearing shell 401b, with both ends of the shaft 402a fixed to the center of one opposite end of the force-bearing shell 401b, and a disc 402b mounted on the shaft 402a, with the disc 402b fixed to the middle of the shaft 402a. It also includes a pressure rod 402c and a pull rod 402d mounted on the disc 402b.

[0052] Furthermore, the linkage assembly 403 includes a driving member 403a disposed on the pressure rod 402c, the driving member 403a being fixed to one outer end of the pressure rod 402c, and a limiting member 403b disposed on the pull rod 402d, the limiting member 403b being fixed to one outer end of the pull rod 402d. It also includes a shaped rod 403c disposed on the driving member 403a and the limiting member 403b, with the shaped rod 403c fixed to opposite ends of both the driving member 403a and the limiting member 403b. The top of the shaped rod 403c located on the driving member 403a... The bottom of the shaped rod 403c on the limiting member 403b is fixed to the bottom of the first air plug 301a. It also includes a limiting surface 403d on the shaped rod 403c. The two shaped rods 403c have a limiting surface 403d at one end of the shaft 402a. After the rotating assembly 402 rotates by 120 degrees, the connecting rod assembly 403 rotates accordingly, thereby driving the limiting surface 403d of the two shaped rods 403c to contact the shaft 402a, thereby forming a limit.

[0053] The driving component 403a includes a driving housing 403a-1, a fixed connection between the top of the driving housing 403a-1 and the corresponding irregular rod 403c, and a sliding groove 403a-2 provided on the driving housing 403a-1. The sliding groove 403a-2 is opened at one end of the driving housing 403a-1 located on the disk 402b. It also includes a driving rod 403a-3 provided on the sliding groove 403a-2, and the driving rod 403a-3 slides inside the sliding groove 403a-2.

[0055] The limiting component 403b includes a limiting shell 403b-1, with a fixed connection between the bottom end of the limiting shell 403b-1 and a corresponding irregular rod 403c. The limiting shell 403b-1 has a groove 403b-2, a first limiting groove 403b-3, and a second limiting groove 403b-4. The limiting shell 403b-1 has a groove 403b-2 at one end of the disc 402b, a first limiting groove 403b-3 on one side of the groove 403b-2, and a second limiting groove 403b-4 on the other side. The device includes a locking rod 403b-5 disposed on a groove 403b-2, which slides inside the groove 403b-2. It also includes a spring 403b-6, a ball bearing 403b-7, and a hollow rod 403b-8 disposed on the locking rod 403b-5. The ball bearing 403b-7 rotates inside the first limiting groove 403b-3. The spring 403b-6 is fixed on the other side of the locking rod 403b-5. The hollow rod 403b-8 slides on the outer wall of the locking rod 403b-5 on one side of the spring 403b-6.

[0056] Hollow rod 403b-8 and tie rod 402d are connected, and the outer wall of hollow rod 403b-8 is fixed to one end of the outer side of tie rod 402d.

[0057] The rest of the structure is the same as in Example 2.

[0058] In use, when the second water plug 201c moves downward to the inlet of the water pipe 101b, it can drive the connecting rod 201b to move downward. The connecting rod 201b drives the first water plug 201a to move downward. The first water plug 201a drives the slider 102g to move downward. The slider 102g drives the irregular rod 403c on the driving member 403a to move downward. The irregular rod 403c drives the driving housing 403a-1 to move downward. The driving rod 403a-3 inside the slide groove 403a-2 also moves downward. During the movement, the driving rod 403a-3 can slide in the slide groove 403a-2. The driving rod 403a-3 can drive the pressure rod 402c to move downward. The pressure rod 402c can drive the disc 402b to rotate 60 degrees. The disc 402b drives the pull rod 402d to rotate upwards by sixty degrees. Since the pull rod 402d is inside the groove 403b-2, it can drive the limiting shell 403b-1 to move upwards. The locking rod 403b-5, located inside the limiting shell 403b-1, moves upwards accordingly. During this process, the ball 403b-7 disengages from the first limiting groove 403b-3 and compresses the spring 403b-6. When it moves to the second limiting groove 403b-4, the rebound force of the spring 403b-6 causes the ball 403b-7 to engage in the second limiting groove 403b-4. The movement of the limiting shell 403b-1 also drives the connected irregular rod 403c to move upwards. This irregular rod 403c can drive the first air plug 301a to move upwards. A first air plug 301a drives a round rod 301b to move upwards. The round rod 301b then drives a second air plug 301d to move to the inlet of the air inlet pipe 101c, thus mates with its water inlet component 200. When the third water plug 201e moves to the inlet of the water inlet pipe 101b, the above steps re-mate the water inlet component 200 and the air inlet component 300. This is mainly achieved by the rotating component 402 rotating another 60-degree angle. The driving component operates as described above, but the limiting component 403b causes its ball bearing 403b-7 to re-engage in the first limiting groove 403b-3 during movement, thus providing a limiting function. At the same time, the limiting surfaces 403d of the two irregular rods 403c contact the shaft 402a, forming a limiting effect and preventing the rotating component 402 from continuing to rotate. In the overall process, when the shaft 402a rotates by 60 degrees, it will drive the fixed force-bearing shell 401b to rotate. The force-bearing shell 401b is constrained by the fixed coil spring 401c, so the fixed coil spring 401c can apply the rebound force to the force-bearing shell 401b. At the same time, the force-bearing shell 401b drives the pull block 401f to move to the other end of the delay groove 401e. When the shaft 402a rotates by 60 degrees again, the shaft 402a drives the force-bearing shell 401b to rotate again. At this time, the force-bearing shell 401b will not only drive the fixed coil spring 401c to coil, but also drive the pull block 401f to move, so that the pull block 401f drives the delay coil spring 401d to coil. At this time, the force-bearing shell 401b has the rebound force of two coil springs, thus adapting to the water pressure, limiting and resetting functions of the above structure.

[0059] In summary, this allows the water inlet component 200 and the air inlet component 300 to operate synchronously, and features step-by-step limit switches and step-by-step pressure settings, enabling them to operate in a compatible manner.
