Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and particularly to a device for recycling waste gas and waste water of a rotary sulfur granulator. Background Art

[0002] Sulfur is a by-product produced by the oil and gas and coal chemical industries. Its initial form is high-temperature liquid, which is not conducive to storage and transportation. Therefore, the liquid sulfur must be cooled, solidified, granulated and formed into a solid form for easy storage, transportation and use.

[0003] At present, the sulfur forming equipment adopted by sulfur recovery enterprises is mainly a rotary sulfur granulator. Although the existing rotary sulfur granulator is equipped with a dust collector, a large amount of waste gas containing water vapor, a small amount of dust, sulfur dioxide and hydrogen sulfide is still discharged into the atmosphere, resulting in a pungent smell around the sulfur recovery production device, and the environment is polluted to a certain extent, affecting the environmental improvement and compliance of sulfur recovery enterprises. In addition, when the existing dust collector collects wet dust, the wet dust is easily adhered to the inner wall of the dehumidifier, which is not conducive to subsequent collection. Therefore, a device for recycling waste gas and waste water of a rotary sulfur granulator is proposed. Summary of the Invention

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a device for recycling waste gas and waste water of a rotary drum sulfur granulator, including a cooling water tank 1, a high-pressure water pump 2, a rotary drum sulfur granulator main body 3, a cyclone dust collector 4, an induced draft fan 5, a condenser 6 and a plurality of pipelines 7. The cooling water tank 1, the high-pressure water pump 2, the rotary drum sulfur granulator main body 3, the cyclone dust collector 4, the induced draft fan 5 and the condenser 6 are connected by a plurality of pipelines 7. The cyclone dust collector 4 includes an air inlet pipe 41 and an air outlet pipe 42. An annular plate 43 is fixedly installed in the cyclone dust collector 4. A self-cleaning delay mechanism 45 is rotatably installed on the top of the annular plate 43. A heating plate 44 is fixedly installed at the bottom of the air outlet pipe 42. The dust-containing waste gas enters the self-cleaning delay mechanism 45 through the air inlet pipe 41 and is heated and dehumidified by the heating plate 44, and the waste gas is discharged through the air outlet pipe 42, and the dry dust falls into the bottom collection cavity of the cyclone dust collector 4.

[0019] The self-cleaning delay mechanism 45 includes a filter plate 452 rotatably sleeved on the air outlet pipe 42. At the bottom of the filter plate 452, there are two elastically helical plates 457 distributed symmetrically about the center. At the ends of the two elastically helical plates 457 far from the center of the circle, fixing rods 454 are fixedly installed. The top and bottom of the elastically helical plate 457 are slidably connected to the filter plate 452 and the annular plate 43 respectively. The tops of the two fixing rods 454 are fixedly connected to the bottom of the filter plate 452. At the ends of the two elastically helical plates 457 close to the center of the circle, second inclined deflector plates 458 are fixedly installed. The self-cleaning delay mechanism 45 further includes a sleeve 455 fixedly sleeved on the air outlet pipe 42, and two first inclined deflector plates 456 are fixedly installed on the side surface of the sleeve 455.

[0020] Furthermore, the two elastically helical plates 457 are not only distributed symmetrically about the center, but also arranged staggeredly. By forming two spiral channels, the time for the dust-containing waste gas to flow through the self-cleaning delay mechanism 45 can be prolonged, so that it can be fully heated. As Figure 6 shown, when the two elastically helical plates 457 rotate clockwise, the two second inclined deflector plates 458 will respectively hook on the corresponding first inclined deflector plates 456. And since the ends of the elastically helical plates 457 far from the center of the circle are fixedly connected to the fixing rods 454, when the positions of the second inclined deflector plates 458 remain unchanged, as the elastically helical plates 457 continue to rotate clockwise, the elastically helical plates 457 will be wound up. When the elastically helical plates 457 are wound up to a certain extent, the ends of the elastically helical plates 457 close to the center of the circle will generate a relatively large pulling force on the second inclined deflector plates 458, prompting them to separate from the first inclined deflector plates 456.

[0021] A conical cover 453 is fixedly installed on the top of the filter plate 452. The conical cover 453 is rotatably sleeved on the air outlet pipe 42. A transfer chamber 451 is formed between the filter plate 452 and the conical cover 453. An exhaust hole 421 communicating with the transfer chamber 451 is opened on the air outlet pipe 42.

[0022] A conical pipe 47 is fixedly installed in the air outlet pipe 42. The bottom end of the conical pipe 47 is located below the exhaust hole 421, and the top end of the conical pipe 47 is located above the exhaust hole 421.

[0023] Furthermore, when there is an upward flowing air current in the air outlet pipe 42, through the cooperation of the conical pipe 47, a negative pressure state will be created inside the transfer chamber 451 through the exhaust hole 421.

[0024] The cyclone dust collector 4 further includes a driving mechanism 46. The driving mechanism 46 includes a gear ring 462 rotatably sleeved on the air outlet pipe 42. The gear ring 462 and the conical cover 453 are fixedly connected through a plurality of connecting rods 464 distributed in a circumferential array. A gear 463 is meshed with the gear ring 462. The driving mechanism 46 further includes a motor 461 fixedly installed on the top of the cyclone dust collector 4. The output shaft of the motor 461 rotatably extends into the cyclone dust collector 4 and is fixedly connected with the gear 463.

[0025] Further, start the motor 461 to drive the gear 463 to rotate. The gear 463 then drives the gear ring 462 to rotate. The gear ring 462 then drives the conical cover 453 to rotate through a plurality of connecting rods 464. The rotation of the conical cover 453 will cause the entire self-cleaning delay mechanism 45 to rotate.

[0026] The induced draft fan 5 is provided with an air inlet end 51 and an air outlet end 52. The condenser 6 is provided with an air inlet end 61. The rotary drum sulfur granulator main body 3 is provided with an air outlet 33. The air inlet end 51 and the air outlet pipe 42 are connected through a pipeline 7. The air outlet end 52 and the air inlet end 61 are connected through a pipeline 7. The air inlet pipe 41 and the air outlet 33 are connected through a pipeline 7.

[0027] The rotary drum sulfur granulator main body 3 is further provided with an air inlet 32 and a discharge port 31. The condenser 6 is further provided with an exhaust end 62. The air inlet 32 and the exhaust end 62 are connected through a pipeline 7.

[0028] The cooling water tank 1 is provided with a water inlet 11 and a water outlet 12. The high-pressure water pump 2 is provided with a water inlet end 21 and a water outlet end 22. The condenser 6 is provided with a liquid inlet 63, a liquid discharge port 64 and a liquid outlet 65. The water inlet 11 and the liquid outlet 65 are connected through a pipeline 7. The water outlet 12 and the water outlet end 22 are connected through a pipeline 7. The water inlet end 21 and the rotary drum sulfur granulator main body 3 are connected through a pipeline 7.

[0029] The condenser 6 contains a plurality of heat exchange thin tubes distributed in an array. The plurality of heat exchange thin tubes share the same liquid inlet 63 and liquid discharge port 64. Heat exchange fins are arranged on the heat exchange thin tubes. The outer side of the condenser 6 is wrapped with a heat insulation layer.

[0030] First, open the liquid inlet 63 on the condenser 6 and connect it to the chilled water system of the utility engineering; make chilled water with a temperature of 4 - 5 °C and a flow rate of 20 - 50 cubic meters per hour enter the tube side of the condenser 6. To ensure the heat exchange effect, the chilled water must enter from the bottom and exit from the top; Start the induced draft fan 5 to make the air circulate in the entire pneumatic conveying pipeline, start the high-pressure water pump 2 to spray cooling water into the main body 3 of the rotating drum sulfur granulator that has been started, and at the same time spray liquid sulfur into the main body 3 of the rotating drum sulfur granulator. The liquid sulfur is double-cooled by the circulating cold air and cooling water in the main body 3 of the rotating drum sulfur granulator, and is quickly solidified into spherical particles and discharged from the product outlet 31; Since the sulfur solidification temperature is about 118 °C, latent heat is released during solidification to vaporize the cooling water into water vapor. At the same time, the circulating cold air driven by the induced draft fan 5 is also in full contact with the liquid sulfur when passing through the inside of the main body 3 of the rotating drum sulfur granulator and is heated to about 80 °C. It entrains fine sulfur dust and mixes with the vaporized water vapor, and a small amount of sulfur dioxide and hydrogen sulfide contained in the liquid sulfur are released due to solidification, forming waste gas containing water vapor, sulfur dust, and a small amount of sulfur dioxide and hydrogen sulfide; It is drawn out from the air outlet 33 of the main body 3 of the rotating drum sulfur granulator by the induced draft fan 5, enters the cyclone dust collector 4 to remove dust, and then is sent into the condenser 6 by the induced draft fan 5; The form usually adopted by the condenser 6 is a finned tube heat exchanger. The finned radiator is one of the most widely used heat exchange equipment in gas-liquid heat exchangers. It achieves the purpose of strengthening heat transfer by installing fins on ordinary base tubes. The heat exchange fine tubes can be made of steel tubes, stainless steel tubes, copper tubes, etc. The heat exchange fins can also be made of steel strips, stainless steel strips, copper strips, aluminum strips, etc. The heat exchange fins are mainly used to increase the contact area between air and the heat exchange fine tubes. When chilled water is passed through the heat exchange fine tubes, it becomes an air condenser. Its principle is: when the hot air containing moisture at about 80 °C enters the air cooler, it immediately contacts the heat exchange fine tubes passing through chilled water and the air temperature is reduced to about 20 °C through heat exchange. At this time, as the temperature of the moist air drops and is lower than the dew point temperature, part of the water vapor in the air condenses into liquid water and flows down the tube wall to the lower water receiving tank of the heat exchanger to collect; finally, it is discharged from the liquid outlet 65 of the condenser and flows into the cooling water tank 1, and finally the high-pressure water pump 2 conveys the recycled water to the main body 3 of the rotating drum sulfur granulator again for liquid sulfur cooling, achieving the purpose of zero wastewater discharge; The air dehumidified and cooled by the condenser 6 is re-conveyed to the air inlet 32 of the main body 3 of the rotating drum sulfur granulator and enters the inside of the main body 3 of the rotating drum sulfur granulator again to participate in the liquid sulfur cooling, forming a recycling of waste gas. During the sulfur granulation production process, no waste gas is discharged into the atmosphere, achieving the purpose of reducing the odor at the sulfur recovery device site and improving the surrounding environment of the production device.

[0031] In this embodiment: The dusty waste gas enters the cyclone dust collector 4 through the air inlet pipe 41. During the process that the dusty waste gas flows through the spiral channel formed by the two elastic spiral plates 457, it will be dried by the heat generated by the heating plate 44. The moisture generated by drying will pass through the filter plate 452 and enter the transfer chamber 451. Then, the moisture in the transfer chamber 451 will enter the air outlet pipe 42 through the exhaust holes 421 and be discharged away through the air outlet pipe 42. The dried waste gas passes through the center of the annular plate 43 and flows through the cyclone dust collector 4 for a period of time, and then enters the inside of the air outlet pipe 42 through the bottom port of the air outlet pipe 42 and is finally discharged from the top port of the air outlet pipe 42. As Figures 3 - 6 shown, during the process that the dusty waste gas flows through the two elastic spiral plates 457, start the driving mechanism 46 to drive the conical cover 453 to rotate clockwise. The conical cover 453 then drives the filter plate 452 and the two elastic spiral plates 457 to rotate clockwise. During the clockwise rotation of the two elastic spiral plates 457, they can sweep across the top of the annular plate 43, so as to scrape off some dust adhered to the top of the annular plate 43 due to dehydration. And during the clockwise rotation of the two elastic spiral plates 457, when the two second inclined deflectors 458 pass through the corresponding first inclined deflectors 456 respectively, the second inclined deflector 458 and the first inclined deflector 456 will be in brief abutting and fixing. Then, as the elastic spiral plate 457 continues to rotate clockwise, the elastic spiral plate 457 will be wound up. During the winding-up process of the elastic spiral plate 457, the top of the elastic spiral plate 457 will sweep across the bottom of the filter plate 452, so as to scrape off some dust adhered to the bottom of the filter plate 452 due to dehydration. When the elastic spiral plate 457 is wound up to a certain extent, the end of the elastic spiral plate 457 close to the center of the circle will generate a greater pulling force on the second inclined deflector 458, causing the second inclined deflector 458 to separate from the first inclined deflector 456. During the separation process of the second inclined deflector 458 and the first inclined deflector 456, the contracted elastic spiral plate 457 will quickly rebound and reset. During this process, the rebounding and resetting elastic spiral plate 457 can shake off some dust adhered to itself due to dehydration.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
