Technical Field

[0001] The invention relates to the field of solid waste treatment equipment, and in particular to a plasma gasification furnace with a gas turbulence device disposed therein. Background Art

[0002] Due to the high degree of urbanization and increased population density in modern society, the amount of urban and rural domestic garbage and various non-domestic garbage is increasing day by day, and the current methods and capabilities for garbage disposal are relatively backward, resulting in bottleneck problems such as garbage siege, water and soil pollution, and environmental pollution that seriously affect the quality of modern life of urban and rural people. Against this background, plasma gasification furnace gasification solid waste technology came into being. Compared with other existing garbage disposal methods, plasma gasification furnace gasification solid waste has the following significant advantages: 1. Reduction of solid waste; 2. Harmless treatment of solid waste; 3. Resource utilization of solid waste.

[0003] However, due to the design defects of the existing plasma gasifier, the airflow field and temperature field distribution in the gasifier cavity during the gasification process is unreasonable, resulting in high heat energy loss during the gasification process, causing the overall economic efficiency of the plasma gasifier gasification project to be low, and the promotion and application of plasma gasifier gasification technology is restricted and affected. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a plasma gasifier with a built-in gas turbulence device, which can not only effectively improve the distribution rationality of the airflow field and temperature field in the furnace chamber, but also significantly improve the overall gasification process and economic efficiency of the plasma gasifier.

[0005] The present invention discloses a plasma gasifier with a gas turbulence device, comprising a cylindrical plasma gasifier furnace wall, wherein the inner area surrounded by the plasma gasifier furnace wall is a plasma gasifier furnace cavity, wherein a plurality of gas turbulence devices are arranged in the plasma gasifier furnace cavity, and the gas turbulence devices are fixedly connected to the plasma gasifier furnace wall.

[0006] Preferably, the flow disturbance devices are evenly distributed along the circumference of the plasma gasification furnace wall, and the distribution circle where the flow disturbance devices are located is concentric with the circle where the cross section of the plasma gasification furnace wall is located.

[0007] Preferably, the turbulence devices are arranged at the same height on the furnace wall of the plasma gasification furnace.

[0008] Preferably, the spoiler devices are all long strip-shaped reinforcing ribs, the cross-section of the reinforcing ribs is semicircular, and the reinforcing ribs are connected to the furnace wall of the plasma gasification furnace in a smooth transition.

[0012] Alternatively, preferably, the reinforcing ribs are all arranged in a spiral shape along the axial direction of the plasma gasification furnace wall.

[0013] The present invention has a simple structure. By arranging a gas turbulence device in the plasma gasification furnace chamber, the air flow field and temperature field distribution inside the plasma gasification furnace are improved, the uniformity of furnace charge combustion is improved, the gasification process time is reduced, the furnace charge utilization rate is improved, and the heat energy loss in the gasification process is reduced. The gasification effect of the plasma gasification furnace is improved as a whole, the difficulty and cost of furnace body design and manufacturing are reduced, and the maintenance cost in the production process is reduced, thereby ultimately achieving the economic goal of energy saving and consumption reduction, which is conducive to the promotion and application of plasma gasification furnace gasification technology.

[0019] The present invention discloses a plasma gasifier with a built-in gas turbulence device, comprising a cylindrical plasma gasifier furnace wall 1, wherein the inner area enclosed by the plasma gasifier furnace wall 1 is a plasma gasifier furnace chamber 2, wherein a plurality of gas turbulence devices are arranged in the plasma gasifier furnace chamber 2, and the gas turbulence devices are fixedly connected to the plasma gasifier furnace wall 1.

[0020] The flow disturbance devices are evenly distributed along the circumference of the plasma gasification furnace wall 1 , and the distribution circle where the flow disturbance devices are located is concentric with the circle where the cross section of the plasma gasification furnace wall 1 is located.

[0021] The turbulence device is arranged at the same height on the furnace wall 1 of the plasma gasification furnace.

[0022] The flow-turbulating devices are all long strip-shaped reinforcing ribs 3 , the cross section of the reinforcing ribs 3 is semicircular, and the reinforcing ribs 3 are connected to the furnace wall 1 of the plasma gasification furnace in a smooth transition.

[0023] The radius of the cross section of the upper portion of the reinforcing rib 3 is greater than the radius of the cross section of the lower portion of the reinforcing rib 3 .

[0024] There are four reinforcing ribs 3. In one embodiment, the reinforcing ribs 3 are all arranged along the axial direction of the plasma gasification furnace wall 1. In another embodiment, the reinforcing ribs 3 are all arranged in a spiral shape along the axial direction of the plasma gasification furnace wall 1.

[0025] During the gasification process of the plasma gasifier, the charge is fed into the furnace chamber 2 of the plasma gasifier through the feed port at the top of the plasma gasifier through the feed mechanism, and descends under the gravity of the charge itself; during this descent, due to the oblique upward blowing force of the high-temperature muzzle evenly distributed around the furnace chamber 2 of the plasma gasifier, an air flow vortex is formed, and the charge is blown to the surroundings of the furnace chamber 2 of the plasma gasifier and concentrated on the surface of the furnace wall 1 of the plasma gasifier, resulting in uneven distribution of charge in the center and surroundings of the furnace chamber 2 of the plasma gasifier, so that the combustion of the charge during the gasification process is uneven. The present invention uses a gas turbulence device evenly distributed on the furnace wall 1 of the plasma gasifier to push the charge in the cyclonic vortex from the surroundings of the furnace chamber into the center of the furnace chamber again, and circulates back and forth, so that the charge burns evenly and the effect of the gasification process is improved.
