Description

Technical Field

[0001] This utility model relates to the field of decomposition furnace equipment, and specifically discloses a device for dispersing alternative fuels into the furnace. Background Technology

[0002] Before being fed into the furnace, alternative fuels need to pass through conveying equipment such as belt conveyors and screw conveyors. To reduce air leakage in the decomposition furnace system, most alternative fuel conveying equipment directly connected to the decomposition furnace equipment is selected from well-sealed conveying equipment such as screw conveyors. During the conveying process, alternative fuels, especially lightweight alternative fuels such as waste fuels, are squeezed and compressed by the conveying equipment, causing them to become entangled, adhere, and agglomerate, forming large and heavy particles. After the material enters the furnace, it cannot be dispersed in a timely and effective manner, resulting in prolonged fuel time in the furnace, incomplete combustion, uneven heat release, and sometimes even collapse of the decomposition furnace due to excessively large particles. This leads to unstable thermal regimes, unsatisfactory coal saving and carbon reduction effects, rapid scaling growth in the cone-shaped feed pipe, and many other adverse effects, restricting the high-quality operation of the decomposition furnace.

[0003] Application number CN202410662476.5 discloses a pure textile alternative fuel dispersing device, including a supporting component, comprising a supporting assembly and a driving assembly disposed on the supporting assembly; a dispersing component, comprising a dispersing component disposed on the supporting assembly and a collecting component disposed on the dispersing component; and a cutting component, comprising a receiving cavity disposed within the dispersing component, a cutting component disposed within the receiving cavity, a limiting component disposed on the cutting component, a pushing component disposed within the receiving cavity, and a resetting component disposed on the pushing component. This invention, by setting dispersing blades with diameters decreasing from large to small, allows waste pure textile to automatically slide along the dispersing blades towards the collecting rod, ultimately winding around the collecting rod. This effectively collects the winding waste pure textile, preventing it from affecting the rotation of the drive shaft, and eliminating the need for machine shutdown for cleaning.

[0004] The above scheme is too complicated. The decomposition furnace has a simple structure and does not require complicated feeding equipment. At the same time, the alternative fuel only needs to be initially broken up and does not need to be too dispersed. The equipment is too expensive and is not suitable for the decomposition furnace. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a device for dispersing alternative fuels into the furnace, so as to solve the technical problem of excessive volume when alternative fuels are fed into the furnace.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for dispersing alternative fuel in a decomposition furnace includes a dispersing unit, a high-pressure air supply unit, and a vibration generating unit, all mounted on the furnace. The dispersing unit comprises a dispersing layer composed of several dispersing rods, each hollow and with exhaust holes on the upper side of the portion of the rod located inside the furnace. The high-pressure air supply unit includes a high-pressure blower and a high-pressure air duct connected to the dispersing rods. The vibration generating unit includes a vibration generator connected to the dispersing rods. This design incorporates a dispersing layer composed of dispersing rods. When alternative fuel falls onto the dispersing rods under its own weight, it disintegrates, achieving initial dispersal. The exhaust holes on the dispersing rods allow high-pressure air to be supplied, blowing up any remaining alternative fuel on the rods and preventing accumulation.

[0008] Optionally, the dispersing layers are arranged in a fan shape, with the dispersing rods of adjacent layers arranged alternately. Using this design, the upper and lower layers of dispersing rods can intercept the vast majority of the alternative fuel, ensuring a high dispersing rate, while the fan shape ensures sufficient dispersing coverage.

[0009] Optionally, the spacing between the same layer of dispersing rods is 150-300mm, and the spacing between upper and lower dispersing layers is 300-800mm, with the lower layer of dispersing rods being longer than the upper layer. This design ensures reasonable spacing, and the longer lower layer of dispersing rods is more conducive to dispersing all the alternative fuel.

[0010] Optionally, the disintegrating bar is hollow inside, and an air inlet is provided on the upper side of one end outside the decomposition furnace, and the high-pressure air pipe is connected to the air inlet.

[0011] Optionally, the outer end of the disintegrating bar has a communication port. The vibration generator includes a transmission bar and a vibration block. The vibration block is located at one end of the disintegrating bar inside the decomposition furnace. One end of the transmission bar is connected to the vibration block, and the other end is connected to the vibration generator. In this design, the transmission bar is provided on the vibration generator, which drives the vibration block to vibrate. The vibration block then drives the disintegrating bar to vibrate. Compared to directly applying vibration to the disintegrating bar, the indirect transmission method has less impact on the decomposition furnace.

[0012] Optionally, a heat-insulating gasket can be inserted into the communication port. This can insulate against heat loss and prevent heat leakage, which could cause temperature changes in the decomposition furnace.

[0013] Optionally, the dispersing rod is elastic and tilted downwards at 5-15°. With this design, when the alternative fuel falls onto the dispersing rod, the rod will move downwards a short distance before bouncing back up, thus propelling the alternative fuel towards the center of the decomposition furnace and preventing its accumulation.

[0014] Optionally, the outer end of the dispersing bar is wrapped with heat-insulating cloth.

[0015] The working principle and beneficial effects of this solution are as follows:

[0016] This solution has a very simple structure, allowing for the modification and installation of existing decomposition furnaces. The modification and installation process is simple, convenient, and cost-effective. The solution utilizes disintegrating rods. The substitute fuel falls onto the disintegrating rods under its own weight, thus dispersing it. If fuel accumulates, a high-pressure blower is activated, injecting high-pressure air into the disintegrating rods and expelling it through exhaust vents. This high-pressure air blows the accumulated substitute fuel off. If fuel adheres to the disintegrating rods, a vibration generator is activated. The vibration generator, via a transmission bar and vibrating blocks, drives the disintegrating rods to vibrate, shaking off the adhering fuel.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0021] The following detailed description illustrates the specific implementation method:

[0022] Example

[0023] An alternative fuel feeding and dispersing device, such as Figure 1 , Figure 2 As shown, it includes a dispersing unit, a high-pressure air supply unit, and a vibration generating unit installed on the decomposition furnace 1.

[0024] The dispersing unit comprises two dispersing layers arranged in a fan shape. Each dispersing layer consists of several dispersing rods 5, with adjacent layers staggered. The spacing between dispersing rods 5 within the same layer is 150-300 mm, and the spacing between upper and lower layers is 300-800 mm. The lower layer's dispersing rods 5 are longer than the upper layer's. During installation, holes are first drilled in the decomposition furnace 1, and then the dispersing rods 5 are fixed to the decomposition furnace 1 using high-temperature resistant sealing material and fixing iron plates.

[0025] The dispersing bar 5 is made of steel and is elastic, with a hollow interior. Several vent holes 6 are provided on the upper right side of the dispersing bar 5, and an air inlet 7 is provided on the upper left side of the dispersing bar 5. A connecting opening is provided on the left side of the dispersing bar 5, into which a heat-insulating gasket 9 can be inserted. The heat-insulating gasket 9 has holes for the transmission bar 4 to pass through. The dispersing bar 5 is inclined downwards at 5-15°. Heat-insulating cloth is wrapped around the outer end of the dispersing bar 5.

[0026] The high-pressure air supply unit includes a high-pressure blower 3 and a high-pressure air duct 8, which is connected to the air inlet 7 of the dispersing bar 5.

[0027] The vibration generating unit includes a vibration generator 2, which includes a transmission bar 4 and a vibration block 10. The vibration block 10 is located at the right end of the disintegrating bar. One end of the transmission bar 4 passes through the communication port and is connected to the vibration block 10 inside the disintegrating bar 5. The other end of the transmission bar 4 is connected to the vibration generator 2.

[0028] In practice:

[0029] In this embodiment, after the alternative fuel enters the decomposition furnace 1, it falls onto the dispersing rods 5 under the influence of gravity. The alternative fuel collides with the dispersing rods 5 and disperses before falling back into the decomposition furnace 1 for combustion. Simultaneously, the dispersing rods 5 are elastic, allowing them to propel the alternative fuel towards the center of the decomposition furnace 1. The double-layered dispersing rods 5 improve the coverage area and dispersing effect.

[0030] Alternative fuel may become stuck between the disintegrating bars 5. Therefore, the high-pressure blower 3 and vibration generator 2 need to be activated intermittently during feeding. When the high-pressure blower 3 is activated, high-speed airflow enters each disintegrating bar 5 through the high-pressure duct 8, preventing the alternative fuel from falling onto the bars 5 by blowing upwards. When the vibration generator 2 is activated, it drives the transmission bar 4 to vibrate, which in turn drives the vibrating block 10 to vibrate, which in turn drives the ends of the disintegrating bars 5 to vibrate, dislodging any stuck fuel. In this embodiment, the heat insulation pads 9 and heat insulation cloth are used to prevent heat loss from the decomposition furnace 1.

[0031] In this embodiment, the vibrating bar is made of flexible steel, and the output end of the vibration generator 2 is connected to the vibrating bar. The outer diameter of the vibrating block 10 is smaller than the inner diameter of the dispersing bar 5, that is, the size of the vibrating block 10 is smaller than that of the dispersing bar 5. When not in use, the vibrating block 10 can be pulled out a certain distance to avoid heat transfer, and when in use, it is inserted back into the deepest part of the dispersing bar 5. If it is relatively convenient to move the vibration generator 2, the vibration generator 2 can also be directly connected to the dispersing bar 5, resulting in a better vibration effect.

[0032] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
