Description

Technical Field

[0001] The invention relates to the technical field of combustion furnaces, in particular to a high-efficiency kiln smoke combustion furnace. Background Art

[0002] A combustion furnace is a device that burns combustible materials to obtain heat. It generally generates heat by burning sugarcane leaves, firewood, straw and other combustibles to heat the air, and uses the heated air to heat other objects. Combustion furnaces have been widely used in the production and manufacturing fields of industry and agriculture.

[0003] The air inlet holes of traditional combustion furnaces are usually located close to the center of the combustion chamber. During the combustion and carbonization process, outside air enters the combustion chamber through the air inlet holes and cannot be fully burned. Instead, it carries unburned smoke with it and is discharged through the flame holes, reducing the combustion efficiency of the fuel inside the combustion chamber and increasing fuel loss. Therefore, we have made improvements to this problem and proposed a high-efficiency kiln smoke combustion furnace. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] The present invention provides a high-efficiency kiln smoke combustion furnace, comprising a furnace shell, wherein one side of the furnace shell is fixedly connected to a wall body 1, and the other side of the furnace shell is fixedly connected to a wall body 2, a feed port is provided at the center end of one side of the wall body 1, and a flame through hole is provided at the center end of the wall body 2 away from the feed port, a plurality of air inlet holes are equidistantly provided on one side of the furnace shell, a combustion chamber is provided inside the furnace shell, a flame is provided inside the combustion chamber, and a drying device is provided inside the flame.

[0006] As a preferred technical solution of the present invention, both sides of the top of the inner wall of the furnace shell are arc-shaped structures, the interiors of the multiple air inlet holes are all connected with the interior of the combustion chamber, and the multiple air inlet holes are rectangular structures.

[0007] As a preferred technical solution of the present invention, the width and height of the feed port are both greater than the width and height of the roaring through hole, and the bottom of the feed port is connected to one side of the bottom of the wall.

[0008] As an optimal technical solution of the present invention, the roar is a polyhedron structure with arc-shaped top sides and a rectangular bottom. The roar is arranged on one side of the interior of the combustion chamber, and one side of the roar is fixedly connected to one side of the second inner wall of the wall.

[0009] As a preferred technical solution of the present invention, a through hole is opened inside the roarer, the inside of the through hole is connected to the inside of the roarer through hole, and the outer wall of the drying equipment is seamlessly fixedly connected to the inner wall of the through hole.

[0010] As a preferred technical solution of the present invention, the length of the roar is greater than the distance between one side of the air inlet and one side of the second inner wall of the wall, and one side of the roar extends to the central end inside the combustion chamber.

[0011] The beneficial effects of the present invention are:

[0012] 1. This high-efficiency kiln smoke combustion furnace has a roar that is longer than the distance between one side of the air inlet and one side of the second inner wall of the wall, and one side of the roar extends to the center end of the combustion chamber. When outside air enters the combustion chamber through the air inlet, since the through hole on the inner side of the roar is located at the center of the combustion chamber, the outside air bypasses the outer wall of the roar and finally reaches the center end of the combustion chamber, so that the air stays in the combustion chamber for a longer time, so that the air is fully burned and carbonized along with the fuel in the combustion chamber, and finally the drying equipment is directly heated by the through hole of the roar. This avoids the situation in which the traditional air inlet is close to the through hole of the roar, so that during the combustion process, the air stays in the combustion chamber for a shorter time, and the fuel and air are not fully burned, but the drying equipment is directly heated by the roar, thereby improving the efficiency of full combustion and carbonization of the fuel and reducing fuel loss.

[0013] 2. This high-efficiency kiln smoke combustion furnace, through the seamless fixed connection between the outer wall of the drying equipment and the inner wall of the through hole, can reduce the temperature drop caused by the long-distance transportation of high-temperature flue gas, improve the heat conduction efficiency of high-temperature flue gas, thereby making full use of the high-temperature flue gas generated by combustion and carbonization, and achieving zero emission to the external environment, which is green and environmentally friendly;

[0014] 3. This type of high-efficiency kiln smoke combustion furnace has arc-shaped inner walls on both sides of the top of the furnace shell, which facilitates the gathering of high-temperature flue gas inside the combustion chamber during the combustion process, thereby increasing the combustion temperature inside the combustion chamber, facilitating full combustion of the fuel, and improving combustion efficiency. The interior of the furnace is connected to the interior of the combustion chamber through multiple air inlet holes, which facilitates the air entering through the air inlet holes to smoothly enter the combustion chamber, facilitating full combustion of the fuel.

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-4 As shown, the present invention is a high-efficiency kiln smoke combustion furnace, including a furnace shell 1, one side of the furnace shell 1 is fixedly connected to a wall 2, the other side of the furnace shell 1 is fixedly connected to a wall 2 3, a feed port 4 is provided at the center end of one side of the wall 1 2, a flame through hole 5 is provided at the center end of the wall 2 3 away from the feed port 4, a plurality of air inlet holes 6 are equidistantly provided on one side of the furnace shell 1, a combustion chamber 7 is provided inside the furnace shell 1, a flame 8 is provided inside the combustion chamber 7, and a drying device is provided inside the flame 8.

[0023] Among them, the top of the inner wall of the furnace shell 1 has an arc-shaped structure on both sides, and the interior of multiple air inlet holes 6 are all connected with the interior of the combustion chamber 7, and multiple air inlet holes 6 are rectangular structures. The top of the inner wall of the furnace shell 1 has an arc-shaped structure on both sides, which makes it convenient for high-temperature flue gas to gather inside the combustion chamber 7 during the combustion process, thereby increasing the combustion temperature inside the combustion chamber 7, facilitating full combustion of the fuel, and improving combustion efficiency. The interior of multiple air inlet holes 6 are all connected with the interior of the combustion chamber 7, so that the air entering through the air inlet holes 6 can smoothly enter the interior of the combustion chamber 7, facilitating full combustion of the fuel.

[0024] Among them, the width and height of the feed port 4 are both larger than the width and height of the roar through hole 5, and the bottom of the feed port 4 is connected to one side of the bottom of the wall 2. The feed port 4 is opened to facilitate the addition of fuel into the furnace shell 1 for combustion through the feed port 4, and serves as a slag discharge port to facilitate the discharge of fuel waste residue after combustion and carbonization.

[0025] Among them, the roar of fire 8 is a polyhedron structure with arc-shaped top sides and a rectangular bottom. The roar of fire 8 is arranged on one side of the interior of the combustion chamber 7, and one side of the roar of fire 8 is fixedly connected to one side of the inner wall of the wall 2 3. Through the arrangement of the roar of fire 8, the high-temperature flue gas generated by the combustion of fuel is conveniently discharged through the roar of fire 8. In addition, the roar of fire 8 is a polyhedron structure with arc-shaped top sides and a rectangular bottom. When the high-temperature flue gas generated by the combustion of fuel passes through the interior of the roar of fire 8, it is affected by the change in the shape of the top of the roar of fire 8, thereby accelerating the flow rate of the high-temperature flue gas inside the roar of fire 8, facilitating the rapid circulation of the high-temperature flue gas, and thereby realizing the rapid heating of the heated items and reducing the heat dissipation during the transmission process.

[0026] Among them, a through hole is opened inside the roarer 8, and the inside of the through hole is connected with the inside of the roarer through hole 5. The outer wall of the drying equipment is seamlessly fixedly connected to the inner wall of the through hole. By seamlessly fixing the outer wall of the drying equipment and the inner wall of the through hole, the temperature drop caused by long-distance transportation of high-temperature flue gas can be reduced, and the heat conduction efficiency of high-temperature flue gas can be improved, thereby making full use of the high-temperature flue gas generated by combustion and carbonization, and achieving zero emissions to the external environment, which is green and environmentally friendly.

[0027] The outer wall of the fire roar 8 is provided with a hole, and the outer wall of the fire roar 8 is provided with a hole. The hole is provided on the inner wall of the fire roar 8 and the hole is provided with a hole. The hole is provided on the inner wall of the fire roar 8 and the hole is provided with a hole.

The hole is provided with a hole.

[0028] Working principle: When working, first add the fuel to be burned through the feed port 4 and ignite it inside the combustion chamber 7. At this time, the outside air enters the combustion chamber 7 through the air inlet 6. Since the length of the roar 8 is greater than the distance between one side of the air inlet 6 and the inner wall of the wall 2 3, and one side of the roar 8 extends to the center end of the combustion chamber 7, when the outside air enters the combustion chamber 7 through the air inlet 6, since the through hole on the inner side of the roar 8 is located in the center of the combustion chamber 7, the outside air bypasses the outer wall of the roar 8 and finally reaches the center end of the combustion chamber 7, so that the air stays in the combustion chamber 7 for a longer time, so that the air is fully burned and carbonized with the fuel inside the combustion chamber 7, and finally the through hole of the roar 8 directly heats the drying equipment, avoiding the traditional air inlet 6 being far away from the through hole of the roar 8 One side is closer, and during the combustion process, the air stays in the combustion chamber 7 for a shorter time, and the fuel and air have not been fully burned, so the drying equipment is directly heated through the flame roar 8, which improves the efficiency of full combustion and carbonization of the fuel and reduces fuel loss. During the combustion process, since the top of the inner wall of the furnace shell 1 on both sides is arc-shaped, it is convenient for the high-temperature flue gas to gather inside the combustion chamber 7 during the combustion process, thereby increasing the combustion temperature inside the combustion chamber 7, facilitating full combustion of the fuel, and improving combustion efficiency. When the high-temperature flue gas passes through the flame roar 8, the shape of the top of the flame roar 8 changes, which accelerates the flow rate of the high-temperature flue gas inside the flame roar 8, facilitating the rapid circulation of the high-temperature flue gas. The feed port 4 facilitates the addition of fuel to the furnace shell 1 for combustion, and finally acts as a slag discharge port to facilitate the discharge of fuel waste after combustion.
