Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology for coke oven charging, and more specifically, to a novel smokeless coal charging guide sleeve. Background Technology

[0002] In the coking process, the coal charging stage is one of the main sources of smoke and dust emissions. The smoke and dust generated during this process pollutes the surrounding atmosphere. Therefore, smokeless treatment of the coal charging stage has become a core focus of environmental protection in the coking industry. According to relevant industry statistics, the emission of smoke and harmful substances during the coal charging process accounts for 70% of the total pollutant emissions from coke ovens. These include highly carcinogenic substances such as benzene-soluble compounds and benzo[a]pyrene. If effective collection and treatment measures are not taken, their fugitive emissions will cause serious pollution to the surrounding air environment.

[0003] Currently, the core technology of existing coal charging guide sleeves for coal charging cars involves the coordinated use of a smokeless coal charging guide sleeve and a single-hole pressure adjustable system for coke ovens. This utilizes single-hole carbonization chamber pressure regulation technology to stabilize the pressure inside the carbonization chamber, thereby ensuring no smoke or dust escapes during the coal charging process and solving the problem of smoke and dust overflow during the charging stage to some extent. However, the existing smokeless coal charging guide sleeves still have significant technical drawbacks: after the coal charging operation is completed, when the guide sleeve is raised from the coke oven charging hole, some smoke and dust remain inside the guide sleeve. This residual smoke and dust will rapidly diffuse into the atmosphere during the lifting process, forming fugitive emissions; the coke oven operates at high temperatures, and after a certain period of use, the oven hole will experience displacement deviations, including horizontal and vertical deviations around the oven hole, as well as changes in the position of the oven hole itself (oven deformation), leading to smoke and dust overflow. With increasingly stringent national environmental protection standards, especially the continuous upgrading of control over fugitive emissions from the coking industry, the problem of smoke and dust overflow during the guide sleeve lifting stage can no longer meet current environmental protection requirements, becoming a key technical bottleneck restricting the realization of smokeless coal loading throughout the entire process.

[0004] Therefore, developing a coal charging guide sleeve that can simultaneously achieve smokeless coal charging and collect residual dust during the guide sleeve lifting stage has become a pressing technical challenge for the coking industry. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This utility model provides a novel smokeless coal charging guide sleeve, which is suitable for the whole process of coal charging car to coke oven carbonization chamber for dust control. It can realize smokeless dust overflow during the coal charging and guide sleeve lifting stages, effectively improve the environmental protection compliance level of coking production, and meet the environmental protection management requirements of the industry.

[0028] This utility model organically integrates the dust collection system with the smokeless coal loading guide sleeve, achieving zero smoke and dust overflow throughout the coal loading process and the guide sleeve lifting stage, meeting increasingly stringent environmental protection control requirements. At the same time, it has the characteristics of simple structure and strong adaptability, and can be directly applied to the transformation and upgrading of existing coal loading cars, reducing the equipment upgrade costs for enterprises.

[0029] This utility model discloses a novel smokeless coal charging guide sleeve, which mainly includes a fixed guide sleeve 1, an upper guide sleeve 2, a corrugated pipe 3, a lower guide sleeve 4, a sealed guide sleeve 5, a lower guide sleeve drive mechanism 6, a dust collection hood 7, and a dust collection pipe 8.

[0030] The upper part of the fixed guide sleeve 1 is fixedly connected to the screw feeder 9 (existing equipment) of the coal loading car, and its position remains unchanged during coal loading operations. The upper guide sleeve 2 is fitted over the fixed guide sleeve 1, and the upper outer wall of the fixed guide sleeve 1 and the upper outer wall of the upper guide sleeve 2 are respectively fixedly installed with a first flange and a second flange.

[0031] The upper part of the bellows 3 is connected to the first flange of the fixed guide sleeve 1, and the lower part is connected to the second flange of the upper guide sleeve 2. The bellows 3 seals the dynamic gap between the fixed guide sleeve 1 and the upper guide sleeve 2 to prevent smoke. When the upper guide sleeve 2 descends, the extension of the bellows 3 can provide an upward reaction force for the upper guide sleeve 2. A spherical sealing ring 21 is installed at the lower end of the upper guide sleeve 2.

[0032] The lower guide sleeve 4 is installed concentrically with the upper guide sleeve 2 and is located below the upper guide sleeve 2. A conical sealing ring 41 is installed above the lower guide sleeve 4. The conical sealing ring 41 has a conical cavity inside, which gradually narrows from bottom to top. The spherical sealing ring 21 is a sphere, which is placed inside the conical cavity.

[0033] The sealing guide sleeve 5 is installed at the lower part of the lower guide sleeve 4 and mainly includes a dust collection hood 51, a blade seal 52, and a coal outlet 53. A third flange is fixedly installed at the lower part of the lower guide sleeve 4, and a fourth flange is fixedly installed at the upper part of the coal outlet 53. The third flange and the fourth flange are sealed and fixedly connected. Support frames are fixedly installed on both sides of the outer wall of the fourth flange, and the two support frames are fixedly connected to the dust collection hood 51, which is a cylindrical structure. The blade seal 52 includes an elastic cylindrical web (approximately 1.5-2 mm thick). A fifth flange is installed on the outer wall of the coal outlet 53, and a sixth flange is installed on the inner wall of the web. The fifth flange and the sixth flange are detachably sealed and fixedly connected. When the coal outlet 53 moves downward and inserts into the furnace hole 11 a certain distance, the blade seal 52 moves downward to contact the perimeter of the furnace hole 11. This not only seals the gap between the sealing guide sleeve 5 and the perimeter of the furnace hole 11, preventing dust from escaping, but also increases the sealing force through the elasticity of the web. Since the blade seal 52 is a vulnerable part, it cannot be welded to the coal inlet 53. Welding would easily deform the blade seal 52. Therefore, the blade seal 52 is detachably connected to the coal inlet 53 for replacement when needed. The purpose of the dust collection hood 51 in this invention is that after the coal inlet 53 moves downwards and inserts into the furnace hole 11 a certain distance, because there is existing equipment on both sides above the furnace hole 11, a safe working space needs to be left for the existing equipment. Therefore, the dust collection hood 7 cannot contact the furnace hole 11. Figure 1 and Figure 2 It can be seen that there is a gap between the dust collection hood 7 and the top of the furnace hole 11. To prevent smoke and dust from flowing out of this gap, a dust collection hood 51 is installed to block this gap. The adjustable pressure system of the single hole of the coke oven can create a slight negative pressure inside the coke oven. The coke oven itself has a dust removal function. The gap between the furnace hole 11 and the coal inlet 53 can be sealed by the blade seal 52, and the smoke and dust will not overflow from the gap. However, when the coke oven has been working for a certain period of time and the furnace hole has a displacement deviation, the blade seal 52 and the area around the furnace hole 11 cannot be completely sealed, and a gap will exist. A small amount of smoke and dust will overflow from the gap. The smoke and dust can be collected by the blocking of the dust collection hood 51, the dust collection hood 7, the dust collection pipe 8 and the ground dust removal station.

[0034] The upper part of the dust collection hood 7 is sealed and fixedly installed on the second flange of the upper guide sleeve 2, while the lower part is suspended. The bellows 3 and the dust collection hood 7 together can completely cover the upper guide sleeve 2, the lower guide sleeve 4, and the sealing guide sleeve 5. A safety space is left between the bottom of the dust collection hood 7 and the furnace hole 11. When the dust collection hood 51 moves to the bottom (the coal outlet 53 moves downward and inserts into the furnace hole 11 a certain distance), the outer wall of the dust collection hood 51 contacts the inner wall of the dust collection hood 7.

[0035] The lower guide sleeve drive mechanism 6 includes a track frame 61, an oil cylinder 62, a moving trolley 63 and a lifting arm 64. The oil cylinder 62 is vertically arranged and equipped with a built-in displacement sensor (model: LH-M-RR40-M0800-2), which can intelligently detect the stroke that the piston rod of each coking chamber should extend and memorize it. The track frame 61 is vertically hung under the steel structure 10 (existing equipment). The upper part of the oil cylinder 62 is fixedly installed on the steel structure 10, and the lower output end is connected to the moving trolley 63. One end of the lifting arm 64 is horizontally fixedly installed on the moving trolley 63, and the other end is connected to the lower guide sleeve 4; a vertical through hole is opened on one side of the dust collection outer cover 7 away from the dust collection pipe 8, and the lifting arm 64 passes through the through hole and can move up and down in the through hole; it should be noted that when the present utility model is in use, the ground dust removal station connected to the dust collection pipe 8 is always started to generate negative pressure suction, and the soot will not overflow from the through hole. The moving trolley 63 is arranged in the track frame 61 and can move in the track frame 61 through rollers under the traction of the oil cylinder 62. The moving trolley 63 can be a rectangular frame, and there are two rollers on each of the upper and lower sides of the frame. The track frame 61 can adopt a channel steel structure, and two vertical sliding grooves are opened on the track frame 61, and the upper and lower rollers are respectively slidably connected in the two vertical sliding grooves. It should be noted that the hydraulic drive structures such as the hydraulic oil tank, hydraulic pump, and hydraulic pipeline supporting the oil cylinder 62 are all conventional configurations and will not be elaborated here.

[0036] The dust collection pipe 8 is fixed under the steel structure 10 and includes a main dust collection pipe 81, a first regulating valve 82, a first flue 83, a second regulating valve 84 and a second flue 85. The outer wall of the dust collection outer cover 7 is provided with a first suction port 71 and a second suction port 72 (the first suction port 71 and the second suction port 72 can be welded to the outer wall of the dust collection outer cover 7) that are connected to its interior. The first suction port 71 is connected to the first flue 83 through a flange, and the first regulating valve 82 is arranged inside the first flue 83 and can adjust the flow rate; the second suction port 72 is connected to the second flue 85 through a flange, and the second regulating valve 84 is arranged inside the second flue 85 and can also adjust the flow rate; adjusting the flow rate is mainly to balance the suction of the two flues. The main dust collection pipe 81 adopts a tee design and is respectively connected to the first flue 83, the second flue 85, and the ground dust removal station (existing equipment). Through the negative pressure of the ground dust removal station, the first flue 83 and the second flue 85 form suction, and then suck the coal charging soot. Since the dust collection pipe 8 as a whole will also move with the dust collection outer cover 7, a corrugated pipe is provided on the connecting pipeline between the main dust collection pipe 81 and the ground dust removal station. The corrugated pipe is hermetically connected to the main dust collection pipe 81, and the corrugated pipe has a telescopic function, so as to realize the movement of the dust collection pipe 8, and the corrugated pipe can meet the displacement deviation requirements.

[0037] The working principle of the present utility model: As Figure 1As shown, the coal charging car travels to the coal-to-chemicals chamber, with the coal inlet 53 concentric with the furnace hole 11. The novel smokeless coal charging guide sleeve of this invention begins operation. The piston rod of the hydraulic cylinder 62 extends, pushing the moving trolley 63 vertically downward within the track frame 61. The lifting arm 64 moves downward with the moving trolley 63, driving the lower guide sleeve 4, which in turn drives the sealing guide sleeve 5 downward. The hydraulic cylinder 62, equipped with a built-in displacement sensor, stops operating when the required stroke is reached. At this point, the coal inlet 53 is inserted a certain distance into the furnace hole 11 to prevent coal dust from spilling out. The blade seal 52 is pressed tightly around the furnace hole 11, sealing it to prevent smoke and dust from overflowing. The smoke and dust collection hood 51 is lowered into place and engages with the dust collection cover 7 to collect smoke and dust emanating from the bottom of the blade seal 52. The upper guide sleeve 2 and the lower guide sleeve 4 are tightly joined together by a spherical sealing ring 21 and a conical sealing ring 41 using the reaction force of the bellows 3 to form a spherical-conical seal. The conical sealing ring 41 has a conical cavity inside (the upper opening is smaller than the lower opening). The spherical sealing ring 21 is located inside the conical cavity, below the upper opening. When the lower guide sleeve 4 moves downward, under the reaction force of the bellows 3, the inner wall of the conical cavity of the conical sealing ring 41 and the outer circumference of the spherical sealing ring 21 are tightly fitted, thus achieving a spherical-conical seal. After the spherical sealing ring 21 and the conical sealing ring 41 are tightly fitted, the lower guide sleeve 4 continues to move downward (until the coal outlet 53 moves downward and inserts into the furnace hole 11 a certain distance), which will bring the upper guide sleeve 2 downward with it. The bellows 3 continues to stretch, giving the upper guide sleeve 2 an upward reaction force, making the seal tighter. By setting the bellows 3, it can adapt to coke oven holes 11 of different heights. The distance the upper guide sleeve 2 moves downward is the stretching length of the bellows 3. The distance the upper guide sleeve 2 moves is not too large, so the distance the dust collection hood 7 moves is also not large. When the lower guide sleeve 4 is lifted upward, the bellows 3 regains its elasticity, and moves the upper guide sleeve 2 upward to reset. The outer wall of the fixed guide sleeve 1 is conical, and the conical slope will limit the upward movement of the upper guide sleeve 2. The upper guide sleeve 2 will reset to its initial position before it moved.

[0038] When the ground station fan starts, a negative pressure is created inside the main dust collection duct 81, drawing dust through flue 1 83 and flue 2 85. Upon receiving the fan start signal, the coal loading process begins immediately. Coal enters the carbonization chamber through the fixed guide sleeve 1, upper guide sleeve 2, lower guide sleeve 4, and sealing guide sleeve 5. Under normal operation, the upper guide sleeve 2 and lower guide sleeve 4, as well as the blade seal 52 and furnace hole 11, maintain a good seal, preventing dust from escaping. However, if the furnace top is uneven or the displacement deviation is too large, poor sealing will cause smoke to escape. The emitted dust will be collected by the dust collection hood 7 and then, with the help of the negative pressure generated by the ground dust removal station, will enter the dust collection duct 8 through suction port 1 71 and suction port 72, respectively, and be drawn to the ground dust removal station for processing.

[0039] After coal loading is completed, the piston rod of hydraulic cylinder 62 retracts, pulling the moving trolley 63 vertically upward within the track frame 61. The lifting arm 64 moves upward with the moving trolley 63, driving the lower guide sleeve 4, which in turn drives the sealing guide sleeve 5 upward. Hydraulic cylinder 62, equipped with a built-in displacement sensor, stops moving when the set stroke is reached. During this process, residual dust in the lower guide sleeve 4 and upper guide sleeve 2 will escape from between them and below the sealing guide sleeve 5. This dust will also be collected by the dust collection hood 7 and then, with the help of the negative pressure generated by the ground dust removal station, will enter the dust collection pipe 8 through suction port 1 71 and suction port 2 72 respectively, and be drawn to the ground dust removal station for processing. After the dust removal is completed, the ground dust removal station stops, the work ends, and the next work cycle begins.

[0040] The dust collection hood of this utility model can collect the smoke and dust emanating from the sealed guide sleeve; the dust collection hood can collect the smoke and dust emanating between the upper and lower guide sleeves; the dust collection hood can collect the smoke and dust overflowing when the guide sleeve is lifted; the dust collection hood, together with the dust collection pipe and the ground dust removal station, can achieve smokeless coal loading throughout the entire process; the dust collection hood is equipped with a No. 1 suction port and a No. 2 suction port, which can simultaneously suck up dust and achieve high dust removal efficiency; both the No. 1 and No. 2 flues are equipped with regulating valves to balance the suction force of the two flues.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein. Such 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 this utility model.
