During the soot blowing operation, due to the poor sealing of the capture device, under the positive pressure generated by the soot blowing compressed air, only a small part of the oxide scale and other impurities in the steel pipe can be smoothly removed by the dust removal system, and most of the dust-containing airflow will directly splash into the workshop environment at the dust outlet end of the steel pipe, causing serious pollution to the workshop environment. On the other hand, the oxide scale has the physical characteristics of high density, high specific gravity and strong abrasion, and the small part removed by the dust removal system is often prone to sedimentation and accumulation in the dust removal pipeline. With the passage of time, the sedimentation and accumulation become more and more serious, and the production line has to be temporarily stopped for maintenance of the dust removal system. Frequent maintenance not only greatly increases the labor intensity of workers, but also seriously disrupts the normal production order, resulting in low production efficiency and high production cost. Therefore, it is particularly important to design a steel pipe finishing production line soot blowing dust removal system to solve the above technical problems. UTILITY MODEL CONTENTS

[0018] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the utility model is not limited to the specific embodiment of the following disclosure.
[0019] The utility model provides a kind of steel pipe finishing production line soot blowing dust removal system, including fixed bracket 1, dust removal pipeline 101 is installed in the fixed bracket 1, the right side of dust removal pipeline 101 is connected with trapping dust suction hood 3 by telescopic device 2, telescopic trapping dust suction hood 3 has good adaptability, can be adapted to different pipe diameter, different length specifications steel pipe 302, the effective sealing of steel pipe 302 ash outlet end end is carried out, avoid the dust removal efficiency of dust removal system due to sealing not strictly and reduce, prevent the phenomenon of iron oxide skin splashing and flying occurs, the right side of trapping dust suction hood 3 is equipped with detachable sealing interface 301, the right end of detachable sealing interface 301 is flexibly sealed with the finished steel pipe 302 of finishing production line, the left end of dust removal pipeline 101 is equipped with cyclone dust collector 4, the top of cyclone dust collector 4 is equipped with dust removal pipeline 401, the right end of dust removal pipeline 401 is connected with dust removal branch pipe 402, the tail end of dust removal branch pipe 402 is equipped with secondary dust raising trapping cover 5, the right end of dust removal pipeline 401 is connected with high efficiency filter cartridge dust collector 6, the left side of filter cartridge dust removal is equipped with wind motor 7, the right end of wind motor 7 is connected between the high efficiency filter cartridge dust collector 6 by auxiliary pipe 701, the bottom of trapping dust suction hood 3, cyclone dust collector 4 and high efficiency filter cartridge dust collector 6 is connected with mobile dust car 8, dust removal pipeline 401 and dust removal branch pipe 402 are all equipped with electric valve 9, the left end of wind motor 7 is connected with exhaust cylinder 702,
[0020] In actual use, the connection part of the dust collection hood 3 and the steel pipe 302 adopts a detachable soft sealing interface. In order to meet the diversity of the production requirements of the pipe diameter of the steel pipe 302, a plurality of different specifications of soft sealing interfaces are provided to ensure that the end of the steel pipe 302 can be effectively sealed during the blowing operation. The dust collection hood 3 adopts a telescopic structure, which can meet the effective sealing requirements of the end of the steel pipe 302 with different length specifications. The telescopic function is realized by a hydraulic transmission mode, which can achieve telescopic operation with different strokes. Before the blowing operation, the corresponding specification of the soft sealing interface is replaced according to the pipe diameter specification of the steel pipe 302 in the production plan. At the same time, according to the length specification of the steel pipe 302 in the production plan, the stroke of the telescopic mechanism is set through the control system, so that the dust collection hood 3 can closely fit the end of the steel pipe 302 to achieve good sealing. In addition, the dust collection hood 3 is divided into two parts in structure. The upper half is a flow equalization and pressure release section, and the lower half is a primary settling bin. During the blowing operation, the high-pressure dust-containing gas flow containing compressed air and iron oxide scale impurities enters the flow equalization and pressure release section, and due to the sudden drop in flow velocity, the pressure is rapidly released. The large particles of iron oxide scale impurities naturally settle to the primary settling bin under the action of gravity, which not only realizes the preliminary separation of large particles of dust and gas, but also avoids the wear of the telescopic sealing part by large particles. The dust-containing gas after pressure release and flow stabilization enters the cyclone dust collector 4 through the dust removal pipeline 101 under the negative pressure of the dust removal system for secondary settling treatment. The large particles of dust naturally settled in the primary settling bin are periodically discharged from the mobile dust discharge vehicle 8 arranged at the bottom of the primary settling bin. A secondary dust raising capture hood 5 is arranged above the dust collection hood 3. The shape of the capture hood is designed to maximize the coverage of the area where dust raising may occur at the end of the steel pipe 302 during the blowing operation. The secondary dust raising capture hood 5 and the dust collection hood 3 form a multi-dimensional three-dimensional capture combination, which effectively avoids the occurrence of positive pressure dust raising accidents of the end of the steel pipe 302 during the blowing operation due to the excessive pressure of the compressed air. The dust-containing gas after the first settling treatment by the dust collection hood 3 enters the cyclone dust collector 4 through the dust removal pipeline 101. The dust-containing gas flow enters the cyclone dust collector 4 in a high-speed rotating state. In this process, the iron oxide scale particles are thrown to the dust collector wall under the action of centrifugal force, and then fall along the wall to the mobile dust discharge vehicle 8 at the bottom of the cyclone dust collector 4. After two-stage settling treatment, the possibility of large particle dust settling in the dust removal pipeline 101 is effectively eliminated. The gas flow after the treatment of the cyclone dust collector 4 still contains some fine dust particles. These gases then enter the high-efficiency filter cartridge dust collector 6 for further filtration treatment to ensure that the particulate matter concentration of the discharged gas meets the environmental protection policy standards. Through the joint use of the primary settling bin of the dust collection hood 3, the cyclone dust collector 4 and the high-efficiency filter cartridge dust collector 6, the advantages of existing multi-stage dust removal technology are fully utilized.The combination avoids the deposition and accumulation of large particle dust in the dust removal pipeline 101, guarantees the safe and stable operation of the dust removal system, and realizes the step-by-step fine filtration from large particles to small particles, ensures that the particulate matter emission concentration of the dust removal system reaches a higher environmental protection policy standard. Compared with the conventional steel pipe 302 processing dust treatment mode, the telescopic dust collection and suction cover 3 in the utility model has good adaptability, can be adapted to steel pipes 302 of different diameters and different length specifications, effectively seals the dust outlet end of the steel pipe 302, avoids the reduction of the dust removal efficiency of the dust removal system due to the poor sealing, avoids the phenomenon of iron oxide skin splashing and flying, the setting of the secondary dust collection cover 5 builds a multi-dimensional three-dimensional collection mode, can timely and effectively capture the positive pressure dust in the dust outlet end of the steel pipe 302 caused by the over-high compressed air pressure in the blowing and dusting operation process, and further improves the dust removal efficiency of the dust removal system.
[0021] Embodiment 1
[0022] As shown in Figs. 1-2 the secondary dust collection cover 5 is located above the detachable sealing interface 301, the fixed frame 1 is also provided with a hydraulic drive device 10, the output end of the hydraulic drive device 10 is connected with the dust collection and suction cover 3,
[0023] The effect of the whole embodiment 1 is that, in use, the dust collection and suction cover 3 is driven by the hydraulic drive device 10 to realize the transverse displacement in cooperation with the movable dust discharging vehicle 8, and the versatility of the overall structure is improved.
[0024] Working principle: the connecting part of the capture dust hood and the steel pipe adopts a detachable soft sealing interface. The steel pipe diameter production demand is diverse, and various specifications of soft sealing interfaces are provided to ensure that the dust outlet end of the steel pipe of various diameters can be effectively sealed during the blowing operation. The capture dust hood adopts a telescopic structure, which can meet the effective sealing requirements of the dust outlet end of the steel pipe of different length specifications. The telescopic function is realized through hydraulic transmission, and different stroke telescopic operations can be achieved. Before the blowing operation, the corresponding specification of the soft sealing interface is replaced according to the pipe diameter specification of the steel pipe in the production plan. At the same time, according to the length specification of the steel pipe in the production plan, the stroke of the telescopic mechanism is set through the control system, so that the capture dust hood can tightly fit the dust outlet end of the steel pipe to achieve good sealing. In addition, the capture dust hood is divided into two parts in structure, the upper half is a flow equalization pressure release section, and the lower half is a primary settling bin. During the blowing operation, the high-pressure dust-containing gas flow containing compressed air, oxide scale and other impurities enters the flow equalization pressure release section, and due to the sudden drop in flow rate, the pressure is quickly released. The large particles of oxide scale impurities naturally settle to the primary settling bin under the action of gravity, not only realizing the preliminary separation of large particles of dust and gas, but also avoiding the wear of the telescopic adjustment sealing part by large particles. The dust-containing gas after pressure release and flow stabilization enters the cyclone dust collector through the dust removal pipeline under the negative pressure of the dust removal system for secondary settling treatment. The large particles of dust naturally settled in the primary settling bin are periodically discharged by the mobile dust unloading car arranged at the bottom of the primary settling bin. A secondary dust raising capture hood is arranged above the capture dust hood, which is designed to cover the area where dust raising may occur at the dust outlet end of the steel pipe during the blowing operation to the greatest extent. The secondary dust raising capture hood and the capture dust hood form a multi-dimensional three-dimensional capture combination, which effectively avoids the occurrence of positive pressure dust raising accidents at the dust outlet end of the steel pipe due to the excessive working pressure of compressed air during the blowing operation. The dust-containing gas after the primary settling treatment by the capture dust hood enters the cyclone dust collector through the dust removal pipeline. The dust-containing gas flow enters the cyclone dust collector and moves at a high speed. In this process, the oxide scale particles are thrown to the wall of the dust collector under the action of centrifugal force, and then fall along the wall to the mobile dust unloading car at the bottom of the cyclone dust collector hopper. After two-stage settling treatment, the possibility of large particle dust settling in the dust removal pipeline is effectively eliminated. The gas flow treated by the cyclone dust collector still contains some fine dust particles, which are then introduced into the high-efficiency filter cartridge dust collector for further filtration treatment to ensure that the particulate matter concentration of the discharged gas meets the environmental protection policy standard.
