Description

Technical Field

[0001] This utility model relates to the field of gasification equipment extraction, specifically to an extraction device for gasifier maintenance. Background Technology

[0002] When the gasification unit is under maintenance, residual H2S, CO, N2, water vapor, etc., will remain in the gasifier, scrubbing tower, cyclone separator, etc. after shutdown. When maintenance work such as removing the burner of the gasifier is carried out, the toxic gases and water vapor in the gasifier will spread rapidly, which will lead to the risk of poisoning, suffocation and burns to the maintenance personnel.

[0003] Based on this, Chinese Patent (Announcement No.: CN221279221U) discloses a gas extraction device for a gasification equipment. This device combines the output ends of several gasification devices and connects them to an extractor. The extractor uses a low-pressure steam generator to apply negative pressure to rapidly extract gas from the gasification devices and transfers the extracted gas to a separator for removal. This effectively ensures that during maintenance of the gasifier, toxic gases and water vapor are quickly extracted through the extractor, guaranteeing that no hot gas, residual syngas, N2, etc., escape from the gasifier during maintenance. This reduces the risk to on-site personnel, prevents burns and suffocation, and protects personnel safety.

[0004] The above solution uses the combined use of an extractor and a steam generator to extract air from the gasification equipment for easier maintenance. However, the steam generator has a high steam usage cost and requires the use of an extractor, making the operation cumbersome and economically inefficient. Utility Model Content

[0010] A control valve, installed on the negative pressure pipeline via a sealing flange, is used to open or close the connection between the exhaust fan and the negative pressure pipeline. As a preferred embodiment, the exhaust fan is detachably installed at one end of the negative pressure pipeline.

[0011] The beneficial effects are: since the exhaust fan and the negative pressure pipeline can be detached and installed, the exhaust fan can be adapted to be installed on the negative pressure pipeline of different gasification equipment, thereby completing the exhaust work of different gasification equipment, which is convenient to operate and can save resources.

[0012] As one of the preferred technical solutions, the exhaust fan is connected to a power supply.

[0017] The beneficial effects are: by setting up casters, the transportation and movement of the exhaust fan are made more convenient, thus facilitating the connection of the exhaust fan to the negative pressure pipelines of different gasification equipment.

[0018] As one of the preferred technical solutions, the support frame is provided with a height adjustment component connected to the exhaust fan.

[0019] As one of the preferred technical solutions, the height adjustment component includes:

[0035] Example 1

[0036] In the existing technology, the output end of the gasification device 1 is connected to an extractor. The extractor uses a low-pressure steam generator to create negative pressure and rapidly extract the gas from several gasification devices 1. This allows the toxic gases and water vapor from the gasifier to be quickly extracted during maintenance. However, the cost of using steam is high, and it needs to be used in conjunction with an extractor, making the operation cumbersome and economically inefficient.

[0037] This embodiment provides a suction device for maintenance of gasification equipment, applied to gasification equipment 1, such as... Figure 1 As shown, it includes:

[0038] Negative pressure pipeline 2 is connected to the output end of gasification equipment 1; wherein, gasification equipment 1 is a gasifier or boiler.

[0039] An exhaust fan 3 is installed at one end outside the negative pressure pipe 2; specifically, the exhaust fan 3 is connected to the power supply 5, so that the exhaust fan 3 is directly powered for operation. Furthermore, the exhaust fan 3 is a blower or an electric fan.

[0040] Control valve 4 is installed on negative pressure pipeline 2 via a sealing flange and is used to open or close the connection between the exhaust fan 3 and negative pressure pipeline 2.

[0041] The specific working process is as follows: When the gasification equipment 1 needs maintenance, open the control valve 4 and connect the exhaust fan 3 directly to the output end of the gasification equipment 1. At this time, the exhaust fan 3 is turned on to generate negative pressure for rapid extraction, ensuring that no hot gas, residual syngas, N2, etc. escape from the gasifier during the maintenance process, reducing the risk of on-site personnel operation, avoiding burns and suffocation, and protecting personnel safety.

[0042] This embodiment replaces the low-pressure steam generator and extractor with an exhaust fan 3. It is understood that a low-pressure steam generator refers to a steam generator whose outlet steam pressure is within a specific range. The equipment contains heating elements, such as electric heaters or burners, which heat the water to a certain temperature when activated. Steam is generated by heating liquid water to a boiling point, and this process consumes a large amount of energy, regardless of whether coal, natural gas, biomass, or electricity is used as the energy source. In industry, large amounts of coal are often burned to generate steam, which significantly increases operating costs and reduces economic efficiency.

[0043] The exhaust fan 3, being directly connected to electricity, can efficiently utilize electrical energy or other forms of energy for operation. Therefore, using the exhaust fan 3 can improve economic efficiency and reduce carbon emissions. In addition, simply aligning the exhaust fan 3 with the negative pressure pipe 2 allows for rapid extraction of energy from the gasification equipment 1, resulting in high working efficiency.

[0044] Example 2

[0045] Based on Embodiment 1, this embodiment provides an extraction device for maintenance of gasification equipment, wherein a support frame 6 is provided at the bottom of the extraction fan 3. The support frame 6 provides a certain height for the extraction fan 3, thereby enabling the extraction fan 3 to be better aligned with the negative pressure pipeline 2 for extraction.

[0046] Furthermore, the exhaust fan 3 can be detachably installed at one end of the negative pressure pipe 2.

[0047] In the existing technology, different gasifiers are placed in different locations. In order to save resources, the output ends of several gasification devices 1 are combined and then connected to the extractor and low-pressure steam generator. At this time, several gasification devices 1 can only be maintained at the same time. However, in actual industrial production, it is impossible to stop all gasification devices 1 for maintenance. This will cause a conflict between the maintenance and operation of gasification devices 1.

[0048] Based on this, the proposed solution replaces the gasification equipment 1 with an exhaust fan 3. The specific effects are as follows: During maintenance, the exhaust fan 3 draws heat from the gasification equipment 1, ensuring that no hot residual syngas or N2 escapes from the gasifier during maintenance. During operation, the control valve 4 closes, disconnecting the exhaust fan 3 from the gasification equipment 1. At this time, the exhaust fan 3 can be removed and used on other gasification equipment 1 requiring maintenance. On the one hand, the exhaust fan 3 can be used independently to maintain the gasification equipment 1; on the other hand, the exhaust fan 3 can be removed to adapt to different gasification equipment 1, improving the utilization rate of the exhaust fan 3 and saving resources.

[0049] Further optimization involves providing casters 7 at the bottom of the support frame 6. The casters 7 facilitate the transportation and movement of the exhaust fan 3, enabling it to be moved and connected to the negative pressure pipelines 2 of different gasification devices 1.

[0050] Further optimization involves installing a height adjustment component 8 on the support frame 6, connected to the exhaust fan 3. Specifically, since different gasification devices 1 are located in different positions, the pulled-out negative pressure pipe 2 may be at different heights. To facilitate the alignment of the exhaust fan 3, the height adjustment component 8 is installed to adjust the position of the exhaust fan 3, ultimately ensuring...

[0051] Furthermore, the height adjustment component 8 includes:

[0052] The lifting plate 81 is connected to the exhaust fan 3 and is slidably arranged on the support frame 6; the support frame 6 includes two vertically placed support rods, and the lifting plate 81 is slidably arranged between the two support rods, so that the two support rods can guide and position the lifting plate 81, and at the same time ensure the smooth lifting and lowering of the lifting plate 81.

[0053] The telescopic part 82 is mounted on the support frame 6 and connected to the bottom of the lifting plate 81, and is used to drive the lifting plate 81 to move up and down. A placement platform is provided between the two support rods for placing the telescopic part 82.

[0054] Specifically, the working process of height adjustment component 8 is as follows:

[0055] When the telescopic part 82 is activated, it moves the lifting plate 81 upward smoothly, thereby moving the exhaust fan 3 upward. At this time, the exhaust fan 3 rises.

[0056] When the telescopic part 82 is activated and retracted, the telescopic part 82 drives the lifting plate 81 to move smoothly downward, thereby driving the exhaust fan 3 to move downward. At this time, the exhaust fan 3 descends.

[0057] Specifically, the telescopic part 82 includes one of an electric telescopic rod, a hydraulic rod, or a cylinder. The telescopic part 82 is automatically driven, thereby making the height adjustment of the exhaust fan 3 more convenient and efficient.

[0058] In the description of this document, some terms may be used to indicate not only orientation or positional relationship, but also other meanings. For example, the term "above" may also be used in some cases to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0059] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
