Description

Technical Field

[0001] This application belongs to the field of combustion furnace technology, and in particular relates to a waste carbonization combustion furnace. Background Technology

[0002] In recent years, with the improvement of people's living standards, the amount of urban domestic waste generated has increased rapidly, resulting in a huge accumulation of waste over the years. Landfilling is the usual method of disposal, causing significant land degradation. Incineration can achieve the most effective treatment of domestic waste while minimizing land use.

[0003] However, existing small-scale waste carbonization incinerators cannot fully utilize the heat energy generated by waste combustion during the carbonization process. Moreover, the drying, carbonization, and combustion processes of waste are not very complete, which can easily lead to incomplete carbonization of waste in the subsequent process. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a waste carbonization incinerator that can improve the utilization rate of heat energy generated by waste combustion and enhance the full carbonization of waste by drying it before combustion.

[0005] This application provides a waste carbonization incineration furnace, comprising: The combustion chamber has a cylindrical combustion space; The burner is tangentially fed into the combustion chamber. The waste input mechanism includes an input cylinder and a first screw conveyor assembly. The first screw conveyor assembly is installed at one end of the input cylinder, and the other end of the input cylinder is connected to the top of the combustion chamber. The input cylinder is installed on a bearing seat and is driven to rotate by a drive device. The heat exchange mechanism includes a first spiral tube, a second spiral tube, a pump body, and a heat exchange cylinder. The first spiral tube is wound around the inner wall of the combustion chamber, the heat exchange cylinder is sleeved on the input cylinder, the second spiral tube is spirally distributed on the inner wall of the heat exchange cylinder, and the heat exchange cylinder is filled with a heat-conducting liquid. A connecting sleeve is movably connected between the first screw conveyor assembly and the input cylinder, and the connecting sleeve is provided with a first outlet.

[0006] The burner operates to carbonize and burn waste in the combustion chamber. The cylindrical combustion space and tangential input of the burner improve efficiency. Waste is transported to the combustion chamber via a waste input mechanism and then pushed into the input cylinder by a first screw conveyor assembly. The first screw conveyor assembly consists of a cylinder, screw, and motor, and is connected to a hoist for easy lifting of waste from lower levels. Heat generated in the combustion chamber is transferred to the input cylinder via a heat exchange mechanism to heat and dry the waste, improving the carbonization effect upon entering the combustion chamber. A first spiral tube, a second spiral tube, and a pump are connected to a water tank. The pump circulates the heat transfer medium (water or oil) in the heat exchange mechanism, and the heat is then transferred through the first spiral tube. The heat exchanger absorbs heat from the combustion chamber. When the heat transfer medium flows into the second spiral tube, it releases heat and conducts it to the heat transfer liquid in the heat exchange cylinder. The heat transfer liquid improves the heat transfer efficiency from the second spiral tube to the input cylinder. The heat exchange cylinder is fixed by a bracket. The input cylinder and the heat exchange cylinder are connected in a movable and sealed manner. The input cylinder is movably mounted on a bearing seat to ensure the stability of the input cylinder when it rotates. The drive device that drives the input cylinder is driven by a motor and is transmitted through a gear structure, sprocket, chain structure, belt, or pulley structure to make the input cylinder rotate, which facilitates the turning of the garbage and improves the drying efficiency of the garbage. The connecting sleeve is movably connected between the input cylinder and the first screw conveyor assembly through a bearing. After the moisture in the garbage is evaporated in the input cylinder, it is discharged through the first outlet.

[0007] A valve plate controls the passage of waste between the input cylinder and the combustion chamber.

[0008] Furthermore, the input cylinder includes: The spiral blade is placed on the inner wall of the input cylinder.

[0009] Spiral blades are distributed on the inner wall of the cylinder. The cross-section of the spiral blades is rectangular, triangular, or T-shaped. When the input cylinder rotates, the spiral blades can push the garbage to move slowly and uniformly from one end of the input cylinder to the other end.

[0010] Furthermore, the combustion chamber includes: A blower, connected to the combustion chamber, is used to supply air.

[0011] Air is introduced into the combustion chamber by a blower to provide oxygen for waste combustion and improve waste combustion efficiency.

[0012] Furthermore, the combustion chamber also includes: The bosses are placed on the inner wall of the combustion chamber and are evenly distributed around the axis of the combustion chamber; The injection port is located on the protrusion and is connected to the blower.

[0013] The boss is set on the inner wall of the combustion chamber and is integrally connected to the combustion chamber. The boss facilitates the setting of the injection holes, which are connected to the blower. The direction of the injection is in the direction of the air vortex flow in the combustion chamber, which further improves the combustion efficiency in the combustion chamber.

[0014] Furthermore, the boss includes: The guide surface is placed on the boss and is opposite to the injection hole.

[0015] The guide surface is made of conical or arc surface to make the air flow more smoothly and ensure the stability of air flow in the combustion chamber.

[0016] Furthermore, it also includes: The second screw conveyor assembly is installed at the bottom of the combustion chamber.

[0017] The second screw conveyor assembly consists of a cylinder, a screw, and a motor. The second screw conveyor assembly can discharge the carbonized residue at the bottom of the combustion chamber, which facilitates the continuous operation of the combustion chamber.

[0018] Furthermore, the second screw conveyor assembly includes: The third spiral tube is wound around the second screw conveyor assembly, and the third spiral tube is connected to the first spiral tube, the second spiral tube, and the pump body.

[0019] The third spiral tube is wound around the second screw conveyor assembly and connected to the heat exchange mechanism. The heat transfer medium from the water tank is transported by the pump body and flows sequentially through the third spiral tube, the first spiral tube, and the second spiral tube before being introduced back into the water tank, further improving the heat utilization rate of the combustion residue on the second screw assembly.

[0020] Furthermore, it also includes: The exhaust pipe is connected to the combustion chamber and the connecting sleeve.

[0021] The top of the combustion chamber and the first outlet of the connecting sleeve are connected to the exhaust pipe for emission, pressure stabilization, etc. The exhaust pipe is connected to dust collectors, activated carbon and other dust removal and adsorption structures to ensure that the air discharged from the exhaust pipe meets emission standards.

[0022] The beneficial effects of this application are: 1. The waste is transported to the combustion chamber through the waste input mechanism, and pushed into the input cylinder by the first screw conveyor assembly.

[0023] 2. The heat generated in the combustion chamber is transferred to the input cylinder through the heat exchange mechanism to heat and dry the garbage inside the input cylinder, thereby improving the combustion and carbonization effect of the garbage after it enters the combustion chamber.

[0024] 3. Heat is transferred to the input cylinder, which rotates to facilitate the turning of the waste and improve the drying efficiency. Attached Figure Description
