Description

Technical Field

[0001] This invention relates to the field of desulfurization and dust removal technology, and in particular to an integrated online desulfurization and dust removal device for a solid waste pyrolysis furnace. Background Technology

[0002] With the acceleration of industrialization, the amount of solid waste generated is increasing, and pyrolysis technology is widely used because it can achieve volume reduction, resource recovery and harmlessness.

[0003] However, the pyrolysis process produces high-temperature flue gas containing sulfides and dust, which, if directly emitted, will pollute the environment and harm health.

[0004] Existing external desulfurization and dust removal equipment has prominent problems: high-temperature flue gas loses heat significantly during pipeline transportation, leading to a decrease in desulfurization efficiency; pipelines are prone to corrosion; the equipment occupies a large space, has low integration, and increases costs; the amount of desulfurizing agent sprayed cannot be dynamically adjusted according to the sulfide concentration, which easily leads to waste or insufficient desulfurization; the spraying device is prone to clogging, requiring frequent shutdowns for cleaning; and the dust collector has a limited filtration area, resulting in poor dust removal effect.

[0010] Preferably, shrink hoods are fixedly installed at the upper and lower ends of the collector and at the outer edge of the air outlet. A triangular shell is fixedly installed inside the collector, and a barrier sponge is installed inside the triangular shell.

[0011] Preferably, filter plates are slidably installed at both ends of the rectangular frame and into the interior, a water tank is fixedly installed at the lower end of the rectangular frame, a water pump is fixedly installed at the rear end of the water tank, and a delivery pipe is fixedly installed at the end of the water pump away from the water tank.

[0012] Preferably, a spraying disc is fixedly installed at the end of the delivery pipe away from the water pump. The spraying disc is fixedly installed inside the protective shell. A symmetrical first sliding groove is formed on the lower circumferential surface inside the protective shell. A slider is slidably installed inside the first sliding groove.

[0013] Preferably, a support ring is fixedly installed at the lower end of the cleaning plate, the support ring is fixedly installed on the inner circumferential surface of the protective shell, a threaded rod is rotatably installed at the center thread of the cleaning plate, a triangular sealing rod is fixedly installed at the upper end of the threaded rod, and the triangular sealing rod is rotatably installed inside the protective shell and located between the upper and lower diverter plates.

[0014] Preferably, a gear ring is fixedly installed on the outer side of the triangular sealing rod. The gear ring is located inside the connecting ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a built-in online desulfurization and dust removal device. The core components are integrated inside the decomposition furnace, realizing the integrated synergy of desulfurization, dust removal and pyrolysis reaction. The built-in structure eliminates long-distance flue gas pipelines, reduces heat loss, maintains desulfurization temperature, and improves desulfurization efficiency. At the same time, the structure is compact, occupies a small area, reduces costs, reduces leakage risk, and improves safety and reliability. It solves the problems of large heat loss, large footprint, and easy corrosion and leakage of pipelines in external equipment.

[0016] 2. This invention uses a servo motor to drive a gear ring to control the opening and closing of the through holes in the diverter plate, dynamically adjusting the amount of desulfurizing agent sprayed according to the sulfur concentration in the flue gas. This achieves precise on-demand application, avoiding resource waste or insufficient desulfurization. The dust collector uses a self-rotating gear that meshes with the tooth grooves on the inner wall of the protective shell. As the gear ring rotates, it synchronously stretches and compresses up and down, ensuring that the filter surface comes into full contact with the flue gas, improving the dust removal effect, ensuring that the exhaust gas meets standards, and solving the problems of uncontrollable desulfurizing agent dosage and incomplete dust removal coverage in traditional equipment.

The synergistic design of multi-stage filtration, multi-layer desulfurization, and recycling allows the flue gas to undergo multiple processes such as coarse filtration, fine filtration, chemical desulfurization, liquid film desulfurization, and dust removal, forming a complete purification chain, improving the efficiency of tail gas treatment, and solving the problems of independent processes, lack of coordination, and unsatisfactory results in existing technologies.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 13 The present invention provides a technical solution: A built-in online desulfurization and dust removal device for solid waste pyrolysis treatment furnace includes two outer shells 1. A decomposition furnace 101 is rotatably installed inside the two outer shells 1 at their far ends. Support frames are fixedly installed on the outer sides of the two far ends to support the outer shells 1. A drive motor 102 is fixedly installed inside the two support frames. Drive wheels 104 with a concave structure in the middle are rotatably installed at both the front and rear ends of the upper part of the two support frames. Finally, a V-shaped drive belt 103 is rotatably installed on the output shaft of the drive motor 102 and the circumferential surface of the drive wheels 104. The drive wheels 104 are in contact with the outer circumferential surface of the adjacent end of the decomposition furnace 101. Figure 3 As shown.

[0023] The two decomposition furnaces 101 are located at opposite ends of each other, serving as feed inlets. The materials to be deheated are transported into the decomposition furnace 101 via an external conveying device.

[0024] Then, during use, the drive motor 102 starts and drives the drive wheel 104 to rotate through the V-shaped drive belt 103, which in turn drives the decomposition furnace 101 to rotate at a set speed. The material is heated evenly inside the decomposition furnace 101 as it rotates, and a pyrolysis reaction occurs, producing flue gas containing sulfides and dust.

[0025] The flue gas enters the interior of the subsequent collector 2 through the end of the decomposition furnace 101.

[0026] It should be noted that heaters 105 are fixedly installed at the front ends of the left and right outer shells 1, and a conveying pipe is fixedly installed between the middle of the heater 105 and the adjacent outer shell 1 for transferring the heat inside the heater 105 to the interior of the decomposition furnace 101, such as... Figure 1 As shown.

[0027] Therefore, during use, the high-temperature heat generated by the heater 105 is continuously transported to the inside of the decomposition furnace 101 through the conveying pipeline, providing a stable and uniform heat source for the pyrolysis reaction of the material and ensuring that the pyrolysis process proceeds efficiently.

[0028] The collector 2 has air inlets 201 at both ends and inside. Each air inlet 201 is fixedly installed with a barrier net 202. It should be noted that the barrier net 202 is made of a special material, preferably a composite material of high temperature and corrosion resistant stainless steel and ceramic fiber. Its surface is treated with an anti-oxidation coating, which can withstand the long-term corrosion of high temperature and sulfides in flue gas, and effectively avoid material aging or damage.

[0029] The pore diameter of the barrier mesh 202 is controlled between 0.5-1mm, which can effectively intercept larger dust particles in the flue gas while ensuring smooth flue gas passage and preventing excessive internal pressure in the collector 2. Simultaneously, the high mechanical strength of the composite material ensures structural stability and resistance to deformation under long-term airflow impact, guaranteeing a consistently reliable dust interception effect and providing a cleaner flue gas environment for subsequent desulfurization processes.

[0030] A discharge port 203 is provided on the left side and inside the collector 2. A sealing block 204 is slidably installed inside the discharge port 203. Figure 6 As shown, during subsequent use, fine waste residue is generated after the water source and flue gas mix during desulfurization, thus requiring discharge. A triangular outer shell 213 is fixedly installed inside the collector 2, and a retaining sponge 214 is nested inside the triangular outer shell 213. Figure 6 and Figure 7 As shown.

[0031] Therefore, during use, the fine waste residue carried by the flue gas will be blocked when it flows through the triangular shell 213 and then roll down along the path of the triangular shell 213, so as to prevent it from entering the subsequent desulfurization process with the flue gas and causing equipment blockage or desulfurizing agent failure.

[0032] At this time, the operator can slide the sealing block 204 along the slide rail of the discharge port 203, so that the collected waste residue is discharged from the discharge port 203 under the action of gravity. The edge of the sealing block 204 is embedded with a high temperature resistant fluororubber sealing strip, which fits tightly with the inner wall of the discharge port 203. In the non-slag discharge state, it can completely block the leakage of flue gas and ensure the stability of the internal pressure of the collector 2.

[0033] In addition, the inclined design of the triangular shell 213 helps the waste residue to gather towards the discharge port 203, improving the slag discharge efficiency.

[0034] It should be noted that the main function of the barrier sponge 214 is to collect and filter the desulfurizing agent and to prevent flue gas from flowing out through the two lower outlets 205.

[0035] The collector 2 has symmetrical air outlets 205 at both its upper and lower ends and inside. A shrink hood 206 is fixedly installed at the outer edge of each air outlet 205. A rectangular frame 207 is fixedly installed at the end of each of the two adjacent shrink hoods 206 furthest from the collector 2. Filter plates 208 are slidably installed at both ends and inside the two rectangular frames 207. Figure 6 As shown.

[0036] Therefore, during use, the flue gas enters the shrink hood 206 through the two upper air outlets 205. The conical structure of the shrink hood 206 can guide the flue gas to flow evenly to the filter plate 208 in the rectangular frame 207. The filter plate 208 is filled with a composite desulfurizing agent of modified activated carbon and calcium hydroxide, which can efficiently adsorb sulfides in the flue gas and further intercept residual fine dust particles.

[0037] When the filter plate 208 becomes saturated with adsorption, the operator can pull out the filter plate 208 along the slide rail of the rectangular frame 207 for replacement or regeneration. The operation is convenient and does not affect the continuous operation of the equipment.

[0038] In addition, the shrink hood 206 is made of high-temperature resistant silicone material, which can adapt to slight vibrations during equipment operation, prevent air leakage at the connection, and ensure the sealing of flue gas treatment. Meanwhile, the side of the rectangular frame 207 is equipped with a transparent observation window, which allows operators to observe the usage status of the filter plate 208 in real time, perform timely maintenance and replacement, and ensure long-term stable operation of the equipment.

[0039] A water tank 209 is fixedly installed at the lower end of the lower rectangular frame 207. A water pump 210 is fixedly installed at one end of the water tank 209. A delivery pipe 211 is fixedly installed at the end of the water pump 210 away from the water tank 209. A spraying disc 212 is fixedly installed at the upper end of the delivery pipe 211. The spraying disc 212 is located inside the subsequent protective shell 215. It should be noted that the interior of the spraying disc 212 is a hollow structure for storing water, and through holes are formed in a ring array from the upper end face to the interior. A hydrophobic diaphragm is fixedly installed inside the through holes to allow flue gas to pass through without allowing the desulfurizing agent to flow out. Figure 9 As shown.

[0040] Therefore, during use, after the water pump 210 is started, the alkaline desulfurization absorbent stored in the water tank 209 is pumped into the cavity of the spray plate 212 through the delivery pipe 211. Since the spray plate 212 is equipped with a hydrophobic diaphragm in the through hole, the absorbent will form a uniform and stable liquid film on the surface of the diaphragm, which will not leak out and will allow the flue gas to pass through smoothly.

[0041] When the flue gas, after preliminary desulfurization and dust removal by the filter plate 208, enters the protective shell 215, it will come into full contact with the liquid subsequently sprayed by the spray plate 212. The residual sulfides in the flue gas will undergo a chemical reaction with the absorbent liquid, further reducing the concentration of pollutants.

[0042] Meanwhile, the subsequent liquid film can also cool the flue gas to a certain extent, reducing the heat load on subsequent equipment. The bottom of the water tank 209 is equipped with a drain valve, which operators can open periodically to discharge the waste liquid after absorbing pollutants and replenish fresh absorbent liquid to ensure the continuous and efficient operation of the spraying system.

[0043] In addition, the installation position of the spray plate 212 is compatible with the internal structure of the protective shell 215 to avoid short circuit of flue gas, ensure the contact time between flue gas and liquid film, and improve the overall desulfurization efficiency.

[0044] Secondly, the sprayed desulfurizing agent can re-enter the water tank 209 after being filtered by the subsequent filter plate 208 and blocked by the secondary blocking and filtration of the blocking sponge 214.

[0045] A connecting ring 216 is fixedly installed on the lower outer side of the protective shell 215. Servo motors 217 are evenly fixedly mounted in a ring array on the upper end face of the connecting ring 216. The output shaft of the servo motor 217 extends into the interior of the connecting ring 216 and is fixedly mounted with a drive gear 218. A gear ring 219 is rotatably mounted inside the connecting ring 216. The gear ring 219 and the drive gear 218 mesh with each other. Figure 11 As shown.

[0046] A triangular sealing rod 220 is fixedly installed on the inner circumferential surface of the gear ring 219. Diverter plates 3 are fixedly installed at both ends of the triangular sealing rod 220, located inside the protective shell 215. Figure 10 As shown, the upper and lower ends of the diverter plate 3 are evenly arranged with through holes in a ring array to allow flue gas to pass through.

[0047] Then, the triangular sealing rod 220 can individually seal the three rows of through holes to prevent the desulfurizing agent from passing through, and is used for spraying and passing the desulfurizing agent according to the degree of operation.

[0048] Secondly, a water spray pipe 301 is fixedly installed on the lower end face of the lower flow plate 3 and at the edge of each through hole. The desulfurizing agent can enter the interior of the water spray pipe 301 through the through hole and then be sprayed out through the fine holes on the surface to mix with the flue gas.

[0049] Then, a threaded rod 302 is fixedly installed on the lower end face of the triangular sealing rod 220 and through the lower diverter plate 3. A cleaning plate 303 is rotatably installed on the circumferential surface of the threaded rod 302. A support ring 403 is fixedly installed on the lower inner circumferential surface of the protective shell 215. The upper end face of the support ring 403 and the lower end face of the cleaning plate 303 are in contact.

[0050] Two sliders 304 are fixedly installed on the circumferential surface of the cleaning plate 303, and a first groove 401 is provided on the inner circumferential surface of the protective shell 215, and the sliders 304 are slidably installed inside the first groove 401.

[0051] Therefore, during use, the cleaning plate 303 can move up and down under the action of the threaded rod 302, and then clean the surface of the water spray pipe 301 to avoid clogging.

[0052] Therefore, in actual operation, the flue gas is discharged from the solid waste pyrolysis furnace and enters the protective shell 215.

[0053] At this time, the system can start the servo motor 217 based on the real-time monitored flue gas sulfur concentration data, and drive the gear ring 219 to rotate through the drive gear 218, so that the triangular sealing rod 220 is adjusted to the corresponding angle. If the sulfur content is high, the triangular sealing rod 220 reduces the number of sealing through holes to allow more desulfurizing agent to pass through; if the sulfur content is low, the number of sealing holes is increased to accurately control the amount of desulfurizing agent used and avoid resource waste.

[0054] The desulfurizing agent flows into the spray pipe 301 of the lower diversion plate 3 through the unsealed through hole. It is sprayed out in a uniform mist through the fine holes on the surface of the spray pipe 301, and mixes fully with the rising flue gas to carry out a desulfurization chemical reaction, effectively removing sulfides from the flue gas.

[0055] As the operation progresses, reaction residues or impurities easily adhere to the surface of the water spray pipe 301. At this time, the servo motor 217 starts again, and the gear ring 219 drives the triangular sealing rod 220 to rotate. Simultaneously, the threaded rod 302 rotates synchronously. Under the guidance and constraint of the slider 304 and the first sliding groove 401, the cleaning plate 303 moves smoothly up and down along the water spray pipe 301, scraping away the blockages on its surface and ensuring that the fine holes are always unobstructed. This design, which integrates desulfurization regulation and self-cleaning functions, not only ensures the stability of desulfurization efficiency but also reduces the frequency of manual cleaning and maintenance, significantly improving the continuous operation capability of the equipment and adapting to the dynamically changing flue gas treatment needs during solid waste pyrolysis.

[0056] Secondly, the upper end face of the upper diverter plate 3 and the lower end face of the spray disc 212 are in close contact.

[0057] Then, symmetrical toothed grooves 402 are provided on the upper inner circumferential surface of the protective shell 215, and a dust collector 501 is provided inside the protective shell 215. The lower outer side of the dust collector 501 and the inside of the protective shell 215 are slidably connected by a groove. Then, a symmetrical self-rotating gear 502 is rotatably installed on the upper end of the dust collector 501. The self-rotating gear 502 and the adjacent toothed grooves 402 mesh with each other, as shown in the figure.

[0058] Therefore, during operation, when the servo motor 217 drives the gear ring 219, the dust collector 501, under the meshing action of the self-rotating gear 502 and the tooth groove 402, drives the dust collector 501 to perform up-and-down stretching and compression operations, so that the filter surface of the dust collector 501 can come into contact with the rising flue gas in all directions and without dead angles, and efficiently capture dust particles in the flue gas.

[0059] This significantly improves dust removal efficiency, ensuring that the flue gas after desulfurization is further purified and meets the environmental protection standards for tail gas emissions from solid waste pyrolysis furnaces.

[0060] Meanwhile, the sliding connection design of dust collector 501 facilitates subsequent disassembly and maintenance, further enhancing the practicality of the equipment, ensuring the fullness of the desulfurization reaction, and enabling the desulfurization and dust removal processes to form a complete synergistic treatment system, significantly improving the overall exhaust gas treatment efficiency.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
