Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization tower equipment, and in particular to an integrated desulfurization tower for a thermal power plant with a regulating component. Background Art

[0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. A spray assembly is set on the top of the desulfurization tower to make the desulfurizer and flue gas contact and react. This reaction method often does not have enough contact area, resulting in incomplete absorption of sulfur dioxide in the flue gas. In the past, by increasing the height of the tower, the residence time of the flue gas in the tower can be increased, thereby providing more reaction time and opportunities for the harmful substances in the flue gas to contact and react more fully with the desulfurizer. However, increasing the height means that more materials are needed and the construction difficulty is higher. In addition, a tower that is too high may lead to uneven airflow distribution, and uneven distribution of the spray layer will reduce the desulfurization efficiency. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The slurry at the bottom of the desulfurization tower body is extracted by three sets of liquid pumps and transported to the spray head by the spray pipe to spray the flue gas. The sprayed slurry will absorb the sulfur dioxide in the flue gas to achieve the purpose of desulfurization. After the sprayed slurry flows into the bottom of the desulfurization tower body, it is filtered through the filter net to obtain the filtered slurry, which is circulated and extracted for spraying. The flue gas after spraying passes through the demister on the upper side to remove the limestone slurry that may be entrained in the flue gas, ensuring that the discharged gas is clean and free of residue.

[0015] 2. When the flue gas initially enters the inner desulfurization pipe, the upper rotating shaft will drive the connected gear disc to rotate through the use of a double-shaft motor, thereby driving several groups of meshing bevel gears to rotate the movable shaft and the fan head in the supporting shaft sleeve, generating an inclined upward airflow to blow the flue gas upward, and the lower rotating shaft and the rotating head of the double-shaft motor are fixed, so that the conical cap, movable pipe, connecting sleeve and internal structure rotate along the rotating head, and several groups of fan heads are driven by the rotation, so that the flue gas blown upward forms a spiral rising state, thereby enhancing the contact effect between the flue gas and the slurry and improving the desulfurization efficiency.

[0016] 3. The spirally rising flue gas is guided to the position between the inner desulfurization pipe and the desulfurization tower body through the flow port and the guide plate. Since the driven groups of fan heads make the gas in the inner desulfurization pipe flow upward, suction is generated at the position below the inner desulfurization pipe, so that the flue gas between the inner desulfurization pipe and the desulfurization tower body enters the inner desulfurization pipe again, and cooperates with the spraying assembly to carry out secondary desulfurization. If the amount of flue gas entering the smoke inlet pipe is large, the speed of several groups of movable pipes is accelerated by adjusting the dual-axis motor to make the spiral rising centrifugal force greater, and more flue gas enters the inner desulfurization pipe and the desulfurization tower body to circulate and complete the secondary desulfurization work. The flue gas moves along the spiral line. Compared with linear motion, the flue gas needs a longer distance to move from the entrance to the exit of the desulfurization tower, which can reduce unnecessary height increase. Through the use of dual-axis motors and hydraulic cylinders, the scraper can be driven to scrape off the slurry on the inner wall. At the same time, the baffle rises to block the flow port position and switch to single-tube operation to meet different needs.

[0017] 4. When the flue gas enters from the lower side of the inner desulfurization pipe, the slurry filtered by the filter screen is extracted through the liquid pump and the suction pipe, and input into the inside of the water inlet ring through the branch pipe. Several groups of atomizing nozzles will form a circular water mist layer to perform the initial desulfurization work on the flue gas entering from the lower side of the inner desulfurization pipe, thereby improving the secondary desulfurization effect. By adding slurry to the inside of the desulfurization tower body, the floating ring and the sleeve ring can float, and the sleeve ring can shield several groups of atomizing nozzles. When the spraying assembly is not in use, it can protect it to avoid blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-Figure 8An embodiment of the present invention is as follows: an integrated desulfurization tower for a thermal power plant with a control component, comprising a mounting frame 1, a platform 2 is fixedly arranged on the upper side of the mounting frame 1, a desulfurization tower body 3 is fixedly arranged inside the mounting frame 1 and the platform 2, a circulation mechanism 4 is arranged inside the desulfurization tower body 3, a spraying assembly 5 is arranged at the bottom of the inner side of the desulfurization tower body 3, the circulation mechanism 4 comprises a smoke inlet pipe 41 fixedly arranged on one side of the desulfurization tower body 3, an inner desulfurization pipe 42 is fixedly arranged at one end of the smoke inlet pipe 41 inside the desulfurization tower body 3, and the inner desulfurization A plurality of groups of rods 43 are fixedly provided at the upper end of the tube 42, a guide plate 44 is fixedly provided at the upper end of the plurality of groups of rods 43, a limiting flow plate 45 is fixedly provided on the inner side of the guide plate 44, a flow port 46 is provided between the plurality of groups of rods 43, a baffle plate 47 is movably provided at a position near the limiting flow plate 45 on the inner side of the inner desulfurization tube 42, four groups of scraping strips 48 are fixedly provided at the lower end of the baffle plate 47, a Y-shaped strip 49 is fixedly provided at the lower side of the scraping strips 48, and a regulating component 410 is provided at a position near the four groups of Y-shaped strips 49 on the lower side of the inner desulfurization tube 42.

[0031] The spirally rising flue gas is guided to the position between the inner desulfurization pipe 42 and the desulfurization tower body 3 through the flow port 46 and the guide plate 44. Since the driven groups of fan heads 41010 make the gas in the inner desulfurization pipe 42 flow upward, suction is generated at the position below the inner desulfurization pipe 42, so that the flue gas between the inner desulfurization pipe 42 and the desulfurization tower body 3 enters the inner desulfurization pipe 42 again, and cooperates with the spraying assembly 5 to perform secondary desulfurization. If the amount of flue gas entering the smoke inlet pipe 41 is large, the speed of the groups of movable pipes 4102 is driven by adjusting the dual-axis motor 4106. The speed is accelerated, so that the centrifugal force of the spiral rise is greater, and more flue gas enters the inner desulfurization pipe 42 and circulates between the desulfurization tower body 3 to complete the secondary desulfurization work. The flue gas moves along the spiral line. Compared with the linear motion, the flue gas needs a longer distance to move from the entrance to the exit of the desulfurization tower, which can reduce unnecessary height increase. Through the use of the dual-axis motor 4106 and the hydraulic cylinder 4105, the scraper 48 can be driven to scrape off the slurry on the inner wall. At the same time, the baffle 47 rises to block the position of the flow port 46, switching to single-tube operation to meet different needs.

[0033] Several groups of supporting shaft sleeves 4103 are inclined, the connecting sleeve 4104 and the movable tube 4102 are an integrated structure, the telescopic rod of the hydraulic cylinder 4105 passes through the interior of the conical cap 4101, the toothed disc 4107 and several groups of bevel gears 4109 are meshed, and several groups of fan heads 41010 are evenly distributed in a circle.

[0034] When the flue gas initially enters the inner desulfurization pipe 42, the upper rotating shaft will drive the connected toothed disc 4107 to rotate through the use of the dual-axis motor 4106, thereby driving several groups of meshing bevel gears 4109 to rotate the movable shaft 4108 and the fan head 41010 in the supporting shaft sleeve 4103, thereby generating an inclined upward airflow to blow the flue gas upward, and the lower rotating shaft of the dual-axis motor 4106 and the rotating head 510 are fixed, so that the conical cap 4101, the movable pipe 4102, the connecting sleeve 4104 and the internal structure rotate along the rotating head 510, and several groups of fan heads 41010 are driven by rotation, so that the flue gas blown upward forms a spiral rising state, thereby enhancing the contact effect between the flue gas and the slurry and improving the desulfurization efficiency.

[0036] The bottom of the filter screen 52 is fixedly connected to the desulfurization tower body 3, and the suction pipe 55 passes through the lower side of the fixed pipe 51 to the cavity between the fixed pipe 51 and the filter screen 52. Several groups of atomizing nozzles 58 are evenly distributed in a circular shape on the water inlet ring 57. The branch pipe 59 is connected to the inside of the water inlet ring 57. The rotating head 510 is rotatably set on the inner side of the connecting sleeve 4104, and the ring 512 is fitted on the upper end of the limiting ring 511.

[0037] When the flue gas enters from the lower side of the inner desulfurization pipe 42, the slurry filtered by the filter net 52 is extracted by the liquid pump 54 and the suction pipe 55, and input into the inside of the water inlet ring 57 through the branch pipe 59. Several groups of atomizing nozzles 58 will form a circular water mist layer to perform primary desulfurization on the flue gas entering from the lower side of the inner desulfurization pipe 42, thereby improving the secondary desulfurization effect. By adding slurry to the inside of the desulfurization tower body 3, the floating ring 513 and the sleeve ring 512 can float, and the sleeve ring 512 can shield several groups of atomizing nozzles 58. When the spray assembly 5 is not in use, it can be protected to avoid blockage.

[0038] Two groups of filling pipes 6 are fixedly arranged on the front side of the desulfurization tower body 3, an air outlet pipe 7 is fixedly arranged on the upper end of the desulfurization tower body 3, three groups of liquid pumping pumps 8 are fixedly arranged on the upper end of one side of the platform 2, liquid pumping pipes 9 are fixedly arranged at the water inlet ends of the three groups of liquid pumping pumps 8, spray pipes 10 are fixedly arranged at the water outlet ends of the three groups of liquid pumping pumps 8, spray heads 11 are fixedly arranged on the inner side of the desulfurization tower body 3 at one end of the upper side of the three groups of spray pipes 10, and a demister 12 is fixedly arranged at a position above the spray head 11 inside the desulfurization tower body 3.

[0039] The filling pipe 6 and the air outlet pipe 7 are both connected to the inside of the desulfurization tower body 3. The liquid extraction pipe 9 passes through the lower side of the desulfurization tower body 3 to the position between the fixed pipe 51 and the filter screen 52. The spray pipe 10 passes through the upper side of the desulfurization tower body 3. The spray head 11 is fixedly installed on the desulfurization tower body 3.

[0040] The slurry (limestone slurry) at the bottom of the desulfurization tower body 3 is extracted by three sets of liquid pumps 8 and transported to the spray head 11 by the spray pipe 10 for spraying the flue gas. The sprayed slurry will absorb sulfur dioxide in the flue gas to achieve the purpose of desulfurization. After the sprayed slurry flows into the bottom of the desulfurization tower body 3, it is filtered through the filter screen 52 to obtain the filtered slurry, which is circulated and extracted for spraying. The flue gas after spraying passes through the demister 12 on the upper side to remove the limestone slurry that may be entrained in the flue gas, ensuring that the discharged gas is clean and free of residue.

[0041] Working principle: During operation, the slurry (limestone slurry) at the bottom of the desulfurization tower body 3 is extracted through three sets of liquid pumps 28, and transported to the spray head 11 through the spray pipe 10 to spray the flue gas. The sprayed slurry will absorb sulfur dioxide in the flue gas to achieve the purpose of desulfurization. After the sprayed slurry flows into the bottom of the desulfurization tower body 3, it is filtered through the filter screen 52 to obtain the filtered slurry for circulation extraction for spraying. The flue gas after spraying passes through the upper demister 12 to remove the limestone slurry that may be entrained in the flue gas, ensuring that the discharged gas is clean and free of residue; and when the flue gas initially enters the inner desulfurization pipe 42, through the use of the dual-axis motor 4106, the upper rotating shaft will drive the connected gear disc 4107 to rotate, thereby driving several meshing settings The bevel gear 4109 makes the movable shaft 4108 and the fan head 41010 rotate in the support sleeve 4103, generating an oblique upward airflow to blow the flue gas upward, and the lower rotating shaft of the double-axis motor 4106 and the rotating head 510 are fixedly arranged, so that the conical cap 4101, the movable tube 4102, the connecting sleeve 4104 and the internal structure rotate along the rotating head 510, and several groups of fan heads 41010 are driven by the rotation, so that the flue gas blown upward forms a spiral rising state, thereby enhancing the contact effect between the flue gas and the slurry and improving the desulfurization efficiency; in addition, the spirally rising flue gas part is guided to the position between the inner desulfurization pipe 42 and the desulfurization tower body 3 through the flow port 46 and the guide plate 44, and the inner desulfurization pipe 42 is formed by the driven several groups of fan heads 41010. The gas in the desulfurization pipe 42 flows upward, which creates suction below the inner desulfurization pipe 42, causing the flue gas between the inner desulfurization pipe 42 and the desulfurization tower body 3 to re-enter the inner desulfurization pipe 42, and cooperate with the spray assembly 5 to perform secondary desulfurization. If the amount of flue gas entering the smoke inlet pipe 41 is large, the speed of several groups of movable pipes 4102 is accelerated by adjusting the dual-axis motor 4106, so that the centrifugal force of the spiral rise is greater, and more flue gas enters the inner desulfurization pipe 42 and the desulfurization tower body 3 to circulate and complete the secondary desulfurization. The flue gas moves along the spiral line. Compared with linear motion, the flue gas needs a longer distance to move from the entrance to the exit of the desulfurization tower, which can reduce unnecessary height increase. By using the dual-axis motor 4106 and the hydraulic cylinder 4105, The scraper 48 is driven to scrape off the slurry on the inner wall, and at the same time, the baffle plate 47 rises to block the position of the flow port 46, switching to single-tube operation to provide different needs; finally, when the flue gas enters from the lower side of the inner desulfurization pipe 42, the slurry filtered by the filter screen 52 is extracted by the liquid pump 54 and the suction pipe 55, and is input into the inside of the water inlet ring 57 through the branch pipe 59. Several groups of atomizing nozzles 58 will form a circular water mist layer to perform initial desulfurization on the flue gas entering from the lower side of the inner desulfurization pipe 42, thereby improving the secondary desulfurization effect. By adding slurry to the inside of the desulfurization tower body 3, the floating ring 513 and the sleeve ring 512 can float, and the sleeve ring 512 can block several groups of atomizing nozzles 58. When the spray assembly 5 is not in use, it can be protected to avoid blockage.

[0042] The desulfurization tower body 3, hydraulic cylinder 4105, dual-axis motor 4106, liquid pump 1 54, atomizing nozzle 58, floating ring 513, liquid pump 2 8, spray head 11, and demister 12 in the present invention belong to the common structural knowledge in this field, and their working principles are already well-known technologies, and the models are selected according to actual use, so they will not be explained in detail.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
