Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, and in particular to a gasifier emission dust collector. Background Technology

[0002] A gasifier converts solid or liquid fuel into combustible gas, which is then mixed with air and burned to achieve heating. Compared to traditional oil-fired furnaces, gasifiers have higher combustion efficiency, saving energy and reducing environmental pollution. Although gasifiers are more environmentally friendly than other furnaces, they still produce smoke and dust during combustion, which needs to be removed before being discharged. However, existing gasifier dust removal devices are mostly bag filters, which only release high-pressure gas through nozzles at the top of the bag filter for dust removal. While this achieves a dust removal effect, the nozzles are located at the top, and the filter bags hang below, requiring a certain amount of time to achieve the desired cleaning effect, resulting in limited cleaning efficiency. Therefore, this application proposes a gasifier dust collector that can achieve highly efficient dust removal. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a gasifier emission dust collector. The technical solution it provides includes a dust collector cylinder, characterized in that: an emission pipe is fixedly connected to the upper end of the dust collector cylinder; an inlet pipe is fixedly connected to the lower side wall of the dust collector cylinder; a closed ring is coaxially fixedly connected to the inner wall of the dust collector cylinder; the upper end of a perforated support is coaxially fixedly connected to the closed ring; mounting brackets are fixedly connected to the upper and lower ends of the perforated support; and a dust collector bag with an open upper end is coaxially arranged on the inner wall of the dust collector cylinder. The outer side wall of the dust collector bag is connected to the perforated support. The bracket is fixedly abutted, and the lower side wall of the dust collector bag is fixedly abutted against the mounting bracket located on the lower side. A lifting device is provided between the two mounting brackets. The lifting device drives a lifting rod. The lifting rod is fixedly connected to an annular tube arranged coaxially with the dust collector cylinder. The annular tube is fixedly connected to a plurality of nozzles evenly distributed around its axis and facing the dust collector bag. An air inlet pipe is fixedly connected to the upper end of the annular tube. A duct is fixedly connected to the upper part of the dust collector cylinder. The outlet end of the duct is fixedly connected to the inlet end of a metal hose. The outlet end of the metal hose is fixedly connected to the inlet end of the air inlet pipe.

[0004] Preferably, the lifting device includes a reciprocating screw that is rotatably connected to the opposite ends of the two mounting brackets. The opposite ends of the two mounting brackets are fixedly connected to two vertical shafts that are symmetrically arranged about the reciprocating screw. The middle part of the lifting rod is fixedly connected to a threaded sleeve that is threadedly connected to the reciprocating screw. The two ends of the lifting rod are respectively fixedly connected to sliding sleeves that correspond one-to-one with the vertical rods and are slidably connected. The upper mounting bracket is fixedly connected to a motor for driving the reciprocating screw.

[0005] Preferably, a dust discharge pipe is coaxially fixedly connected to the lower end of the dust collector, and a dust discharge valve is installed on the dust discharge pipe.

[0006] Preferably, an upward-directing fan is installed at the bottom of the discharge pipe. The beneficial effects of this utility model are: In use, the flue gas discharged from the gasification furnace is introduced into the dust collector through the flue gas inlet pipe. The flue gas entering the dust collector is moved upwards by the fan. During this upward movement, particulate matter such as dust contained in the flue gas is blocked by the dust collector bags, thus removing the particulate matter. The flue gas, after being cleaned by the dust collector bags, can be discharged through the exhaust pipe. When it is necessary to clean the dust collector bags, the motor of the lifting device is started, and then high-pressure gas is introduced into the duct. The high-pressure gas then enters the annular pipe through the metal hose and the inlet pipe, and is released from the nozzles on the annular pipe. Under the action of the lifting device, the annular pipe reciprocates along the axis of the dust collector bags, and the high-pressure gas released from the nozzles can blow the dust collector bags from top to bottom, thus efficiently completing the dust collector bag cleaning operation. This application has a simple structure, is easy to use, and is highly practical. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: During use, the flue gas discharged from the gasification furnace is introduced into the dust collector 1 through the flue gas inlet pipe 3. The flue gas entering the dust collector 1 moves upward under the action of the fan 21. During this upward movement, particulate matter such as dust contained in the flue gas is blocked by the dust collector bag 7, thus removing the particulate matter. The flue gas that has been cleaned by the dust collector bag 7 can then be discharged through the discharge pipe 2. When it is necessary to clean the dust collector bag 7, the motor 22 of the lifting device 8 is started, and then high-pressure gas is introduced into the input conduit 13. The high-pressure gas then sequentially enters the annular pipe 10 through the metal hose 14 and the inlet pipe 12, and is released from the nozzle 11 on the annular pipe 10. Under the action of the lifting device 8, the annular pipe 10 reciprocates along the axis of the dust collector bag 7, and the high-pressure gas released from the nozzle 11 can blow the dust collector bag 7 from top to bottom, thus efficiently completing the dust cleaning operation of the dust collector bag 7.

[0017] In Example 2, based on Example 1, specifically, in use, the conduit 13 can be connected to an external compressed gas storage device to deliver high-pressure gas to the conduit 13 and to purge the dust collector bag 7 with the high-pressure gas. This application will not describe the specific structure of the external compressed gas storage device.

[0018] During operation, the fan 21 is activated to guide the flue gas upwards and release it from the discharge pipe 2. During dust removal, the flue gas generated by the gasification furnace is introduced into the dust collector 1 through the inlet pipe 3. Particulate matter such as dust in the flue gas is blocked by the dust collector bags 7, thus achieving dust removal. The gas, after passing through the dust collector bags 7, is discharged from the discharge pipe 2 under the guidance of the fan 21. The dust collector bags 7 in this application have an open top and sealed bottom structure, fixed by the perforated bracket 5 and the mounting bracket 6. The sealing ring 4 is fixedly installed on the upper end of the dust collector bags 7, thereby forming a certain closed structure at the bottom of the dust collector 1, ensuring that the flue gas can only flow upwards through the dust collector bags 7, thus ensuring the dust removal effect.

[0019] When the dust collector bag 7 needs to be cleaned after a certain period of use, the dust discharge valve 20 is opened so that the dust blown by the nozzle 11 can fall downwards and be discharged through the dust discharge pipe 19. Then, the external compressed gas storage device is connected to the conduit 13 and the motor 22 of the lifting device 8 is started. The start of the motor 22 of the lifting device 8 will drive the reciprocating screw 15 between the two mounting brackets 6 to rotate. The rotation of the reciprocating screw 15 will drive the lifting rod 9 through the screw sleeve 17. The lifting rod 9 is restricted by the cooperation between the sliding sleeve 18 and the vertical shaft 16. Therefore, under the drive of the reciprocating screw 15, the lifting rod 9 will move back and forth along the vertical shaft 16. As a result, the annular pipe 10 fixedly connected to the lifting rod 9 will move back and forth vertically in sync. Thus, the nozzle 11 on the annular pipe 10 can blow the dust collector bag 7 as it moves back and forth.
