Description

Technical Field

[0001] This utility model relates to the field of slurry dewatering technology, specifically to a desulfurization slurry dewatering system for thermal power plants. Background Technology

[0002] With the increasing emphasis placed on environmental protection by the state, higher requirements are being placed on the reliable operation of desulfurization systems in thermal power plants. The desulfurization slurry dewatering system is a crucial component of the overall desulfurization system, playing a vital role in its normal operation. In lime-gypsum desulfurization systems, the quality of the slurry is critical to the safe and stable operation of the entire system, affecting equipment lifespan, desulfurization efficiency, and the quality of byproducts. In particular, many power plants lack sufficient understanding of the impact of chloride ions in the slurry on the desulfurization system, resulting in a high failure rate for the entire system.

[0003] Wastewater needs to be treated during the desulfurization slurry dewatering process in thermal power plants. However, when it is necessary to clean the filtered impurities after the common desulfurization slurry dewatering wastewater treatment equipment in thermal power plants filters them, it is often necessary to manually clean the inside of the filter equipment. However, the space inside the filter equipment is relatively small, which makes it inconvenient to carry out cleaning and reduces the convenience of operation. Utility Model Content

[0015] 1. The desulfurization slurry dewatering system of this thermal power plant, through the set moving mechanism, allows the support arm to move the filter screen out of the wastewater tank. At the same time, the slider can slide and limit its movement on the inner wall of the fixed tank.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 6 A desulfurization slurry dewatering system for thermal power plants includes a support column 1, a wastewater tank 2 fixedly connected to the top of the support column 1, a support frame 3 fixedly connected to the top of the wastewater tank 2, a steam-water separator 4 fixedly connected to the inner side of the support frame 3, a moving mechanism 5 inside the wastewater tank 2, and a reinforcing mechanism 6 outside the wastewater tank 2.

[0030] The moving mechanism 5 includes a fixed arm 51, which is fixedly connected to the back of the wastewater tank 2. A motor 52 is fixedly connected to the inner side of the fixed arm 51. A threaded rod 53 is fixedly connected to the output end of the motor 52. A synchronization component 54 is provided on the outer wall of the threaded rod 53. A threaded rod 55 is provided inside the synchronization component 54. Threaded blocks 56 are threadedly connected to the outer walls of both the threaded rod 53 and the threaded rod 55. A support arm 57 is fixedly connected to the bottom of the threaded block 56. A filter screen 59 is fixedly connected to the bottom of the support arm 57. A slider 501 is fixedly connected to the bottom of the filter screen 59. A limit shaft 58 is fixedly connected to the inner wall of the wastewater tank 2. A fixing groove 503 is fixedly connected inside the wastewater tank 2. A sealing plate 502 is fixedly connected to the front of the filter screen 59.

[0031] Furthermore, the threaded block 56 has a sliding hole inside, and the threaded block 56 is slidably connected to the outer wall of the limiting shaft 58 through the sliding hole, so that the threaded block 56 can be stably slidably limited on the outer wall of the limiting shaft 58.

[0032] Furthermore, the back of the wastewater tank 2 is provided with rotating holes that match threaded rod 1 53 and threaded rod 2 55 respectively. Threaded rod 1 53 and threaded rod 2 55 pass through the corresponding rotating holes and rotate, providing stable support for threaded rod 1 53 and threaded rod 2 55.

[0033] Furthermore, the slider 501 is slidably connected to the inner wall of the fixing groove 503, and the slider 501 is fixedly connected to the back of the sealing plate 502 to provide stable support for the filter screen 59.

[0034] Furthermore, the sealing plate 502 is movably connected to the front of the wastewater tank 2, and the threaded rod 53 is connected to the threaded rod 55 through the synchronization component 54 to achieve stable transmission.

[0035] Example 2

[0036] See Figures 1 to 6 Furthermore, based on Embodiment 1, the reinforcement mechanism 6 further includes a right-angle plate 61, which is fixedly connected to the outside of the wastewater tank 2. A threaded rod 62 is rotatably connected inside the right-angle plate 61. A threaded plate 63 is threadedly connected to the outer wall of the threaded rod 62. A retaining pin 64 is fixedly connected inside the threaded plate 63. A connecting plate 65 is fixedly connected to the outside of the sealing plate 502, which facilitates ensuring the stability of the reinforcement of the sealing plate 502.

[0037] Furthermore, the connecting plate 65 has a locking hole inside, and the locking shaft 64 is movably connected to the inner wall of the locking hole, so that the locking shaft 64 can be inserted into the inner wall of the locking hole to limit the connecting plate 65.

[0038] Furthermore, the threaded rod 62 is rotatably connected to the outside of the wastewater tank 2, and a handwheel is fixedly connected to one end of the threaded rod 62. The threaded plate 63 is slidably connected to the outer wall of the right-angle plate 61, so that the threaded plate 63 can drive the locking shaft 64 to move stably.

[0039] In actual operation, when this device is used, the vacuum belt dehydrator is first connected to the steam-water separator 4. The waste liquid generated by the vacuum belt dehydrator can be discharged into the steam-water separator 4 to remove the gas. The treated wastewater can be discharged into the wastewater tank 2. When the wastewater enters the wastewater tank 2, the impurities will be filtered onto the top of the filter screen 59. The wastewater will be discharged downwards and then discharged through the drain pipe on the left side of the support column 1, thereby achieving the purpose of filtration.

[0040] When it is necessary to clean the impurities filtered at the top of the filter screen 59, the handwheel can be turned to rotate the threaded rod 62. Since the threaded rod 62 and the threaded plate 63 are threadedly connected, and the threaded plate 63 can slide and limit on the outside of the right-angle plate 61, the rotational motion of the threaded rod 62 is converted into the linear motion of the threaded plate 63. The threaded plate 63 can drive the retaining shaft 64 to move out of the inside of the connecting plate 65, thereby removing the limit on the connecting plate 65 and facilitating further cleaning operations. At the same time, with the mutual reinforcement of the retaining shaft 64 and the connecting plate 65, the stability of the limit on the filter screen 59 can be ensured, so that it will not move out of the inside of the wastewater tank 2 during the filtration process.

[0041] After the limiting position on the connecting plate 65 is removed, the motor 52 can be started. The output end of the motor 52 can drive the threaded rod 53 to rotate. The threaded rod 53 can drive the threaded rod 55 to rotate through the transmission of the synchronous component 54. Since the threaded rod 55 and the threaded rod 53 are respectively threadedly connected to two threaded blocks 56, and the threaded blocks 56 slide and limit on the outer wall of the limiting shaft 58, the threaded blocks 56 will drive the support arm 57 to move. The support arm 57 can drive the filter screen 59 to move out of the wastewater tank 2. At the same time, the slider 501 can slide and limit on the inner wall of the fixed groove 503. When the filter screen 59 moves out of the wastewater tank 2, the impurities filtered by the filter screen 59 can be cleaned. When it is necessary to clean the filtered impurities, it is not necessary to manually go into the filter equipment for cleaning, which facilitates cleaning and enhances the convenience of operation.
