Description

Technical Field

[0001] The utility model belongs to the technical field related to the high-efficiency dust cleaning device for ash hopper gasification plates, and particularly relates to a high-efficiency dust cleaning device for ash hopper gasification plates. Background Technique

[0002] The high-efficiency dust cleaning device for ash hopper gasification plates is a dust cleaning technology for industrial equipment. Through a specially designed gasification plate and high-pressure air flow system, it can effectively remove dust and deposits inside equipment such as boilers and heat exchangers. This device can automatically control the dust cleaning process and monitor the equipment status in real time, thereby improving the thermal efficiency, reducing the maintenance cost, and extending the service life of the equipment.

[0003] In the current ash hopper dust cleaning system of pulse bag filters, a bin wall vibrator is usually used for dust cleaning. The main disadvantages include that it may generate noise and is not applicable to all materials. Due to the existence of vibration, the bin wall vibrator may generate a certain amount of noise during operation and some measures need to be taken for noise reduction. In addition, due to the different characteristics of materials, the bin wall vibrator may not have an obvious improvement effect on the fluidity of some materials, which means it may not be applicable to all types of materials and a suitable treatment method needs to be selected. Due to the structure of the electric vibrator itself, its service life is much shorter than that of ordinary motors, which may cause the electric vibrator to burn out, resulting in losses, affecting production and triggering accidents. Therefore, a new type of high-efficiency ash hopper gasification plate dust cleaning system is needed to solve the problems currently faced. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-efficiency dust cleaning device for ash hopper gasification plates to solve the problems mentioned in the above background technique. In the current ash hopper dust cleaning system of pulse bag filters, a bin wall vibrator is usually used for dust cleaning. The main disadvantages include that it may generate noise and is not applicable to all materials. Due to the existence of vibration, the bin wall vibrator may generate a certain amount of noise during operation and some measures need to be taken for noise reduction. In addition, due to the different characteristics of materials, the bin wall vibrator may not have an obvious improvement effect on the fluidity of some materials, which means it may not be applicable to all types of materials and a suitable treatment method needs to be selected. Due to the structure of the electric vibrator itself, its service life is much shorter than that of ordinary motors, which may cause the electric vibrator to burn out, resulting in losses, affecting production and triggering accidents. Therefore, a new type of high-efficiency ash hopper gasification plate dust cleaning system is needed to solve the problems currently faced.

[0005] To achieve the above object, the utility model provides the following technical solution: a high-efficiency dust cleaning device for a hopper gasification plate, which includes a storage hopper. A silicon carbide gasification plate is installed at the outer wall position of the storage hopper. A gas source pipeline is connected to the right end position of the silicon carbide gasification plate. An electric heater is installed at the lower end position of the gas source pipeline. A connecting pipeline is installed at the upper right side position of the electric heater. A Roots blower is installed at the other end position of the connecting pipeline. An air inlet is provided at the upper end position of the Roots blower. Through the insertion hole at the upper end position, a protective housing is installed at the upper end position of the air inlet.

[0008] Preferably, the electric heater sends the heated compressed air into the gas source pipeline.

[0009] Preferably, the gas source pipeline transports the gas source to the silicon carbide gasification plate.

[0013] Compared with the prior art, the utility model provides a high-efficiency dust cleaning device for a hopper gasification plate, which has the following beneficial effects:

[0014] 1. The high-efficiency hopper gasification plate cleaning system of this device is mainly composed of silicon carbide gasification plate, air source pipeline, electric heater, Roots blower, etc. When working, the Roots blower sends the compressed air heated by the electric heater into the air source pipeline, and then sends it to the gasification plate through the air source pipeline. The bottom pipe of the gasification plate device is introduced, and the air enters the material layer evenly through the gasification plate, so that the material in the hopper is loose and fully fluidized, thereby avoiding the arch and bridging phenomenon of the material in the hopper, increasing the fluidity of the material, and ensuring the continuous, stable and safe operation of the production. The air permeable layer material of the gasification device is made of silicon carbide, which has sufficient strength and good air permeability, ensuring its effectiveness and durability. In this way, the gasification plate not only solves the problem of material fluidity, but also helps the smooth progress of the cleaning process, avoids the accumulation of dust, and improves work efficiency.

[0015] 2. The gasification plate is used at the bottom of the ash bin and ash hopper of coal-fired power plants. Heating air passing through the gasification plate can fully fluidize the dry ash and ensure smooth ash unloading. The gasification device's air permeable layer material is made of silicon carbide, and the shell is a steel structure. The gasification plate made of silicon carbide has sufficient strength, a smooth surface, and good air permeability. The gasification plate has good air permeability and wear resistance. The galvanized surface of the tank body is pickled. The tank body is formed in one step and adopts a compression molding process. The box body and the joints are guaranteed to be airtight and have a beautiful appearance. Adjustments are made before assembling the shape to eliminate all welding deformations and internal stresses, to ensure that the bottom surface and the flange joint are smooth and straight, anti-oxidation and not easy to rust. The gasification plate and the box shell are assembled with high-temperature resistant sealing glue.

[0016] 3. This device is equipped with dustproof cotton at the air inlet of the Roots blower. When the air inlet adsorbs gas, the gas will enter the air inlet through the dustproof cotton, which can prevent dust and impurities from entering the internal position of the Roots blower and causing damage to the Roots blower. When disassembling, manually pull the protective shell upwards to make the expansion rubber plug detach from the insertion hole, and then remove the dustproof cotton for cleaning.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] The utility model provides an efficient ash cleaning device for a hopper gasification plate as shown in Figures 1-3 Figure 9, which includes a bin hopper 5. A silicon carbide gasification plate 1 is installed at the outer wall position of the bin hopper 5. A gas source pipeline 2 is connected to the right end position of the silicon carbide gasification plate 1. An electric heater 3 is installed at the lower end position of the gas source pipeline 2. A connecting pipeline 6 is installed at the upper right position of the electric heater 3. A Roots blower 4 is installed at the other end position of the connecting pipeline 6. An air inlet 8 is arranged at the upper end position of the Roots blower 4. The air inlet 8 is installed with a protective housing 9 through an insertion hole 12 at the upper end position. The expansion rubber plugs 11 fixed at the lower left and right positions of the protective housing 9 are inserted into the insertion hole 12. A dust-proof cotton 10 is arranged at the inner side position of the protective housing 9.

[0023] The efficient ash cleaning system for the hopper gasification plate mainly consists of a silicon carbide gasification plate 1, a gas source pipeline 2, an electric heater 3, a Roots blower 4, etc. During operation, the Roots blower 4 sends the compressed air heated by the electric heater 3 into the gas source pipeline 2, and then through the gas source pipeline 2 into the gasification plate again, which is introduced through the bottom connecting pipe of the gasification plate device and evenly enters the material layer through the gasification plate, making the materials in the bin hopper 5 in a loose state and fully fluidized, thereby avoiding the phenomena of arching and bridging of the materials in the bin hopper 5, increasing the fluidity of the materials, and ensuring the continuous, stable and safe operation of production.

[0024] As shown in Figure 1 Figure 9, the Roots blower 4 is supported by a support table body 7 at the lower end position. The Roots blower 4 conveys the gas to the inner position of the electric heater 3 through the connecting pipeline 6. The electric heater 3 sends the heated compressed air into the gas source pipeline 2. The gas source pipeline 2 conveys the gas source to the silicon carbide gasification plate 1. The Roots blower 4 is communicated with the connecting pipeline 6 through the air outlet at the left end position. When the Roots blower 4 blows air, the air inlet 8 sucks the surrounding gas source into the inner position. The dust-proof cotton 10 can prevent the dust and impurities in the gas from being sucked into the inner position of the Roots blower 4.

[0025] The ash cleaning of the gasification plate is mainly applied to dust removal equipment. By heating or other means, the accumulated ash is gasified, so as to achieve the purpose of ash cleaning. This method is suitable for dealing with the accumulated ash that is difficult to directly remove, and realizes the ash cleaning effect by changing the physical state of the accumulated ash. The ash cleaning of the gasification plate is usually used to deal with the accumulated ash with large viscosity or difficult to remove by simple mechanical means. Its advantage is that it can effectively deal with the difficult-to-remove accumulated ash and improve the operation efficiency and cleanliness of the equipment.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
