Description

Technical Field

[0001] The present application relates to the technical field of decomposition furnaces, and in particular to a decomposition furnace feeding device. Background Art

[0002] The decomposition furnace is a device that disperses and suspends raw material powder in the air flow, allowing the fuel combustion and calcium carbonate decomposition process to occur in a very short time. It is a high-efficiency direct combustion chamber solid-gas phase heat exchange device.

[0003] In recent years, the coordinated disposal of solid waste and alternative fuels have been widely used in the cement industry. Using alternative fuels to replace part of the coal can effectively reduce the emission of carbon dioxide and other harmful substances, help protect the environment, and at the same time reduce part of the fuel costs and reduce carbon emissions.

[0004] At present, when alternative fuels are fed into the decomposition furnace, due to the single feeding point, the dispersion of the alternative fuels after entering the decomposition furnace is low, which affects the combustion efficiency of the alternative fuels, makes the addition amount of the alternative fuels low, and increases energy consumption. Summary of the invention

[0005] The purpose of the embodiment of the present application is to provide a decomposition furnace feeding device to ensure that the alternative fuel is evenly dispersed after entering the interior of the decomposition furnace, increase the amount of alternative fuel added, and reduce energy consumption.

[0006] The present application provides a decomposition furnace feeding device, which adopts the following technical solutions:

[0007] A decomposition furnace feeding device comprises a spreading box, which is arranged on the decomposition furnace. The spreading box is arranged to tilt downward at one end close to the decomposition furnace, a spreading plate is arranged at the lower end of the interior of the spreading box, and a plurality of guide plates are arranged on the spreading plate, and the distance between two adjacent guide plates close to the side of the spreading box is smaller than the distance between the two adjacent guide plates away from the side of the spreading box.

[0008] Preferably, the angle between the spreading plate and the horizontal line is 4° to 6°.

[0009] Preferably, the end of the guide plate away from the spreading plate is a conical structure.

[0010] Preferably, a plurality of grooves are provided on the spreading plate, and the grooves are located between two adjacent guide plates.

[0011] Preferably, the material spreading box is provided with a material poking hole.

[0012] Preferably, the spreading plate is made of heat-resistant steel.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] The present application adds a spreading plate inside the spreading box, and the alternative fuel enters the spreading box and falls on the spreading plate, and the alternative fuel collides with the spreading plate, thereby achieving dispersion of the alternative fuel.

[0015] By arranging a plurality of guide plates on the spreading plate, the alternative fuel will slide along the area between two adjacent guide plates after falling on the spreading plate, thereby improving the dispersion effect of the alternative fuel.

[0016] Since two adjacent guide plates extend in an eight-shaped shape from the side close to the material spreading box to the side away from the material spreading box, the opening angle is increased, so that the alternative fuel can have better contact with the material inside the decomposition furnace, thereby improving the combustion efficiency of the alternative fuel and the addition amount of the alternative fuel, reducing energy consumption and improving economic benefits.

[0030] Example

[0031] like Figure 1-4 As shown, the decomposition furnace feeding device described in the embodiment of the present application includes a spreading box 1, which is arranged on the decomposition furnace 2, and the end of the spreading box 1 close to the decomposition furnace 2 is inclined downward, and a spreading plate 3 is arranged at the lower end of the interior of the spreading box 1, and a plurality of guide plates 4 are arranged on the spreading plate 3, and the distance between two adjacent guide plates close to the side of the spreading box 1 is smaller than the distance between the two adjacent guide plates 4 away from the side of the spreading box 1.

[0032] After the alternative fuel enters the spreading box 1, it falls on the spreading plate 3. The alternative fuel collides with the spreading plate 3, thereby achieving dispersion of the alternative fuel. After falling on the spreading plate 3, the alternative fuel will slide along the area between the two adjacent guide plates 4, thereby improving the dispersion effect of the alternative fuel. Since the two adjacent guide plates 4 expand in an eight-shaped shape from the side close to the spreading box 1 to the side of the two adjacent guide plates 4 away from the spreading box 1, the opening angle is increased, so that the alternative fuel can have better contact with the material inside the decomposition furnace 2, thereby improving the combustion efficiency of the alternative fuel and the amount of alternative fuel added, reducing energy consumption and improving economic benefits.

[0033] In this embodiment, the angle between the spreading plate 3 and the horizontal line is 4° to 6°. In a specific implementation, the angle between the spreading plate 3 and the horizontal line is 5°.

[0034] In this embodiment, the end of the guide plate 4 away from the spreading plate 3 is a conical structure. When the alternative fuel collides with the end of the spreading plate 3 away from the spreading plate 3, due to the small contact area, a large stress will be generated at the time of contact, thereby improving the dispersion of the alternative fuel and avoiding the accumulation of alternative fuel on the upper end of the spreading plate 3.

[0035] In this embodiment, a plurality of grooves 5 are provided on the spreading plate 3, and the grooves 5 are located between two adjacent guide plates 4, thereby increasing the height difference between the alternative fuel and the spreading plate 3, improving the interaction force between the alternative fuel and the spreading plate 3, and improving the dispersion degree of the alternative fuel, so that the alternative fuel can better contact with the material inside the decomposition furnace 2.

[0036] In this embodiment, the material spreading box 1 is provided with a material poking hole 6, and the material poking hole 6 is used to clean the crust.

[0037] In this embodiment, the spreading plate 3 is made of heat-resistant steel. The heat-resistant steel has oxidation resistance, sufficient high-temperature strength and good heat resistance under high temperature conditions.

[0038] The working principle of a decomposition furnace feeding device according to the embodiment of the present application:

[0039] After the alternative fuel enters the spreading box 1, it falls on the spreading plate 3. The alternative fuel collides with the spreading plate 3, thereby achieving dispersion of the alternative fuel. After falling on the spreading plate 3, the alternative fuel will slide along the area between the two adjacent guide plates 4, thereby improving the dispersion effect of the alternative fuel. Since the two adjacent guide plates 4 expand in an eight-shaped shape from the side close to the spreading box 1 to the side of the two adjacent guide plates 4 away from the spreading box 1, the opening angle is increased, so that the alternative fuel can have better contact with the material inside the decomposition furnace 2, thereby improving the combustion efficiency of the alternative fuel and the amount of alternative fuel added, reducing energy consumption and improving economic benefits.

[0040] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
