[0030] Example 1

[0031] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a cleaning structure, which includes a carrying unit 100, the carrying unit 100 includes a tower body 101, a transmission assembly 102 arranged in the tower body 101 and a dust collector 103 installed on the top of the tower body 101, and the tower body 101 is connected to the transmission assembly 102; the desulfurization unit 200 includes an adjusting assembly 201 rotating in the transmission assembly 102 and a cleaning assembly 202 fixedly installed on the adjusting assembly 201.

[0032] When in use, the flue gas can be wet desulfurized through the tower body 101. Through the cooperation between the transmission component 102 and the tower body 101, the slurry in the tower body 101 can drive the transmission component 102 to operate, thereby driving the adjustment component 201 and the cleaning component 202 to rotate. And through the setting of the adjustment component 201, the rotation speed of the adjustment component 201 and the cleaning component 202 can be controlled to achieve turbulence of the flue gas.

[0033] Example 2

[0034] Reference Figures 2 to 6 , which is the second embodiment of the present invention, is different from the first embodiment in that: it also includes two forced reflux pumps 101a fixedly connected to the bottom of the tower body 101 and communicating therewith, and three-dividing pipes 101c fixedly connected above the two forced reflux pumps 101a, one end of which penetrates the tower body 101 and is embedded in the interior of the tower body 101.

[0035] Furthermore, one end of the three-branch pipe 101 c located in the tower body 101 is U-shaped, and the transmission assembly 102 is fixedly installed on the U-shaped end of the three-branch pipe 101 c.

[0036] The two forced reflux pumps 101a are in a state of one standby and one in operation. When the operating forced reflux pump 101a is damaged, the standby forced reflux pump 101a is opened in time to ensure the operation of the device and avoid affecting the desulfurization efficiency. The slurry at the bottom of the tower body 101 can be transported to the top of the tower body 101 through the three-branch pipe 101c, and sprayed down through the desulfurization unit 200 to desulfurize the flue gas introduced through the input pipe 101b.

[0037] Through the U-shaped setting at one end of the three-part pipe 101c, it can be connected to the first mounting cylinder 102a and the second mounting cylinder 102d respectively, and the first mounting cylinder 102a and the second mounting cylinder 102d are located on the same central axis, and the rotation of the transmission component 102 can be controlled to ensure the normal operation of the device.

[0038] Specifically, the transmission assembly 102 includes a first mounting tube 102a fixed to the upper part of the U-shaped end of the three-part pipe 101c, a rotating shaft 102b rotating through the center of the first mounting tube 102a, and a fan blade 102c fixed to the rotating shaft 102b and located in the outer circle of the middle part of the first mounting tube 102a. The first mounting tube 102a is connected to the three-part pipe 101c.

[0039] The arrangement of the rotating shaft 102b and the fan blades 102c in the first mounting tube 102a is such that when the slurry flows in the three-dividing pipe 101c, the flow of the slurry can push the fan blades 102c, thereby driving the rotating shaft 102b to rotate, and further driving the desulfurization unit 200 to rotate. The arrangement of the rotating shaft 102b and the fan blades 102c does not affect the flow of the slurry. In addition, the rotating connection between the rotating shaft 102b and the first mounting tube 102a is connected by sealed bearings to prevent slurry from leaking.

[0040] Specifically, the lower part of the U-shaped end of the three-part pipe 101c is fixedly connected to the second mounting tube 102d, the second mounting tube 102d is connected to the three-part pipe 101c, the upper and lower ends of the second mounting tube 102d are both provided with 101e, and the first mounting tube 102a and the second mounting tube 102d are on the same central axis.

[0041] The setting of the second mounting cylinder 102d can provide support for the adjustment component 201. The first mounting cylinder 102a and the second mounting cylinder 102d are on the same central axis, which can ensure that the rotating shaft 102b is connected to the center of the third mounting cylinder 201a, so that when the rotating shaft 102b rotates, it drives the adjustment component 201 to rotate. The U-shaped setting of the three-part pipe 101c not only improves the supporting strength of the desulfurization unit 200, but also can achieve multiple coordination with the desulfurization unit 200 to realize the rotation of the desulfurization unit 200 and the speed control of the desulfurization unit 200.

[0042] Specifically, the adjustment assembly 201 includes a third mounting tube 201a arranged coaxially with the second mounting tube 102d, two sealed bearings 201b fixed to the outer rings at both ends of the third mounting tube 201a, and a first through groove 201c and a second through groove 201d opened on the third mounting tube 201a. The third mounting tube 201a rotates on the inner ring of the second mounting tube 102d, the two sealed bearings 201b are respectively adapted to the two placement grooves 102e, and the top of the third mounting tube 201a is fixed to the bottom end of the rotating shaft 102b.

[0043] Furthermore, the first through groove 201c and the second through groove 201d are both located between the two sealed bearings 201b, and the width of the first through groove 201c is wider than the width of the second through groove 201d, and the third mounting tube 201a is connected to the three-branch 101c through the first through groove 201c and the second through groove 201d.

[0044] Furthermore, a fixing plate 201e is fixedly connected to the bottom of the third mounting tube 201a, and a water delivery rod 201f is fixedly mounted on the outer ring of the fixing plate 201e.

[0045] The rotational cooperation between the third mounting cylinder 201a and the inner ring of the second mounting cylinder 102d can ensure that the third mounting cylinder 201a is driven to rotate when the rotating shaft 102b rotates, and the cooperation between the two sealing bearings 201b and the placement groove 102e can seal the third mounting cylinder 201a and the second mounting cylinder 102d to prevent slurry leakage, which causes the pressure in the three-branch pipe 101c to decrease, resulting in too little slurry being sprayed out or the distance being too close, thereby reducing the desulfurization efficiency. The number of water delivery rods 201f and cleaning components 202 can be set according to actual usage to ensure the desulfurization efficiency of the flue gas.

[0046] The opening of the second through groove 201d and the first through groove 201c enables the slurry to flow smoothly from the three-dividing pipe 101c into the third mounting cylinder 201a, and enter the internal cavity of the scraper 202a through the fixed plate 201e and the water delivery rod 201f. The difference in size between the second through groove 201d and the first through groove 201c can change the flow rate of the slurry entering the third mounting cylinder 201a, and thereby change the flow rate of the slurry in the three-dividing pipe 101c.

[0047] When the first through groove 201c corresponds to the outlet of the three-branch pipe 101c, the slurry flow rate is faster, which drives the rotating shaft 102b to rotate faster, thereby making the rotation speed of the third mounting cylinder 201a faster. When the third mounting cylinder 201a rotates, it will also drive the water delivery rod 201f and the cleaning component 202 to rotate. When the water delivery rod 201f and the cleaning component 202 rotate, the slurry sprayed can be spread over a wider range, thereby improving the desulfurization efficiency. On the other hand, when rotating, the flue gas can be disturbed, so that the flue gas rises with the rotation of the cleaning component 202, which can increase the turbulence of the flue gas and improve the mixing between gas and liquid, thereby improving the mass transfer efficiency and desulfurization effect. In addition, when the cleaning component 202 rotates, it will change the flow field distribution of the flue gas in the tower, which may cause the flue gas to be more evenly distributed and reduce the situation of excessive local concentration.

[0048] When the second through slot 201d rotates to correspond to the three-dividing pipe 101c, the flow rate of the slurry will slow down due to the smaller size of the second through slot 201d. When the slurry flow rate slows down, the thrust on the fan blade 102c will also slow down. At this time, the rotation speed of the rotating shaft 102b and the adjusting component 201 will also slow down accordingly. At this time, since the flue gas is still rotating rapidly, the slowdown in the rotation speed of the rotating shaft 102b and the adjusting component 201 will disturb the flow of the flue gas. When the adjusting component 201 rotates at different speeds, it helps to distribute the slurry and flue gas more evenly, avoiding local oversaturation or drying. By changing the rotation speed, the dead zone of the flue gas flow in the tower body 101 can be reduced, and the utilization rate of the entire tower body 101 can be improved, thereby improving the desulfurization efficiency of the flue gas.

[0049] Specifically, the cleaning component 202 includes a scraper 202a arranged at one end of the water supply rod 201f, and the scraper 202a is fixedly connected to a mounting sleeve 202b on the side close to the water supply rod 201f. The mounting sleeve 202b is fixedly sleeved on one end of the water supply rod 201f. A groove 202c is provided on the side of the scraper 202a close to the water supply rod 201f, and a baffle 202d is provided in the groove 202c. The upper and lower ends of the baffle 202d are fixedly connected to a fixing rod 202e, and the fixing rod 202e is rotatably engaged with the groove 202c; the inner ring of the scraper 202a is provided with a nozzle 202f and a fin 202g, and the nozzle 202f is connected to the cavity in the scraper 202a.

[0050] When the scraper 202a follows the rotation of the adjustment component 201, it can scrape the inner wall of the tower body 101 to ensure the cleanliness of the inner wall of the tower body 101. Through the setting of the baffle 202d, when the scraper 202a follows the third installation cylinder 201a to rotate faster, the baffle 202d will be in the groove 202c, and the scraper 202a will clean the inner wall of the tower body 101 normally. When the speed of the scraper 202a slows down, due to inertia and the impact of the rapid rotation of the flue gas, since the side of the baffle 202d away from the scraper 202a is chamfered, there is a certain gap between the baffle 202d and the side wall of the groove 202c. At this time, the baffle 202d will rotate around the fixing rod 202e rotates, and the baffle 202d and the groove 202c change from horizontal to vertical, which will block the rotation of the flue gas and make the flue gas rotation chaotic, so that the flue gas can be more evenly distributed in the tower body 101, which can further improve the efficiency of flue gas desulfurization. When the rotation speed of the scraper 202a becomes faster again, the baffle 202d will re-enter the groove 202c, and repeat in sequence to ensure the desulfurization efficiency of the flue gas. Through the setting of the fin 202g, when the scraper 202a rotates, it can also drive the flue gas to circulate upward, and because the scraper 202f rotates fast and slow, it can also extend the smoke dwelling time, which can improve the desulfurization efficiency of the flue gas.

[0051] The scraper 202a can be fixed on the water delivery rod 201f through the installation sleeve 202b, and the slurry can be smoothly transported to the cavity of the scraper 202a and sprayed out through the nozzle 202f. The number of nozzles 202f here can be adjusted according to actual conditions, and the direction of the water flow sprayed by the nozzle 202f is toward the center of the tower body 101, and the sprayed slurry presents a vertical fan shape. The setting of multiple nozzles 202f can ensure the desulfurization efficiency of the flue gas, and the nozzle 202f sprays toward the center without blocking the movement of the scraper 202a.

[0052] During use, when the device is running, the flue gas enters the tower body 101 through the input pipe 101b, and the slurry at the bottom of the tower body 101 is transported to the top of the tower body 101 through the three-dividing pipe 101c by opening a forced reflux pump 101a. When the slurry flows in the three-dividing pipe 101c, it can drive the rotating shaft 102b to rotate through the fan blade 102c, and the rotation of the rotating shaft 102b drives the third mounting cylinder 201a to rotate. The slurry will enter the third mounting cylinder 201a through the first through groove 201c and the second through groove 201d, and be sprayed out from the nozzle 201g through the transmission of the fixed plate 201e and the water delivery rod 201f, contact with the flue gas, and desulfurize the flue gas.

[0053] Example 3

[0054] Reference Figures 1 to 7, which is the third embodiment of the present invention, and is based on the previous two embodiments. This embodiment provides a wet desulfurization two-stage tower energy-saving method, which includes an energy-saving unit 300, and the energy-saving unit 300 includes a primary tower 301, a forced cyclone 302 and a ditch 303. The three-branch pipe 101c in the carrying unit 100 is externally connected to a first pipe that is connected to the primary tower 301 and the forced cyclone 302 respectively, and a first valve is provided on the first pipe. The three-branch pipe 101c in the carrying unit 100 is externally connected to a second pipe that is connected to the ditch, and a second valve is provided on the second pipe. A density meter and a pH meter are provided on the second pipe.

[0055] During use, the parameters of the slurry can be measured by the setting of the density meter and the pH meter to ensure the desulfurization efficiency of the flue gas. The height of the slurry in the tower body 101 is 8m from the ground, and the density meter and the pH meter are 3m from the ground. The second pipeline is connected to the ditch, and the liquid self-circulation can be achieved according to the liquid level difference between the two. When the forced reflux pump 101a is stopped, the slurry parameters can be detected to reduce energy consumption.

[0056] In summary, when the device is running, the smoke enters the tower body 101 through the input pipe 101b, and the slurry at the bottom of the tower body 101 is transported to the top of the tower body 101 through the three-branch pipe 101c by opening a forced reflux pump 101a. When the slurry flows in the three-branch pipe 101c, the fan blade 102c can drive the rotating shaft 102b to rotate, and the rotation of the rotating shaft 102b drives the third installation cylinder 201a to rotate, and the slurry will pass through the first through groove 201 c and the second through groove 201d enter the third installation cylinder 201a, and are sprayed out from the nozzle 201g through the transmission of the fixed plate 201e and the water delivery rod 201f, contacting the flue gas and desulfurizing the flue gas. After the flue gas passes through the dust collector 103, the particles entrained in the flue gas after desulfurization can be collected, and through the setting of the second pipeline, the density meter, pH meter and the liquid level difference of the slurry can be self-circulated to the ditch to ensure the detection of slurry parameters and the efficiency of desulfurization.
