Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbonization equipment technology, specifically to a carbonization pyrolysis device. Background Technology
[0002] Carbonization, also known as dry distillation, carbonization, or coking, refers to the reaction process of heating and decomposing solid or organic matter under air-isolated conditions, or a method of heating solid substances to produce liquid or gaseous products (usually turning them into solids).
[0003] In the carbonization furnaces of related technologies, the fire burns in a fixed heating chamber at the bottom of the furnace, while the material inside remains stationary. Heat needs to be slowly transferred to all the material, resulting in a slow and uneven process. To solve this problem, a drum-type carbonization furnace has been introduced to the market. By feeding the material into the front feed port of the carbonization drum, the material can be evenly contacted with the fire at the bottom, thus enabling the material to be fully carbonized.
[0004] However, existing heating chambers all rely on burners to supply heat energy to heat the bottom of the carbonization furnace. This results in significant deficiencies in heat utilization efficiency and environmental performance, as it fails to fully utilize the heat energy during combustion, leading to some heat energy being emitted without being fully utilized, thus causing energy waste and emission problems. To address these issues, a carbonization pyrolysis device is proposed. Utility Model Content
[0005] In view of this, the present invention provides a carbonization pyrolysis device. The present invention uses an induced draft fan to transport most of the lost heat energy to the distribution valve through the return gas pipeline and the exhaust gas pipeline. Then, the distribution valve is connected to the combustion chamber through the circulation pipeline, so that the returned hot gas is supplied to the combustion chamber for secondary utilization. In this way, the heat energy in the combustion chamber can be fully utilized, reducing heat loss and energy waste.
[0006] To solve the above-mentioned technical problems, this utility model provides a carbonization pyrolysis device, including a heating chamber sealed on the surface of the main body of the carbonization furnace, a combustion chamber connected to the front end of the heating chamber, a tail gas pipe at the end of the carbonization furnace, a burner connected to the front end of the combustion chamber, the heating chamber including a cylinder on the surface of the carbonization furnace, a heating chamber connected to the bottom of the cylinder, multiple ventilation pipes in the heating chamber, the ventilation pipes connected to the cylinder, a pair of return gas pipes connected to the top of the cylinder, an induced draft fan at the outlet end of the return gas pipes, a circulation pipe at the outlet end of the induced draft fan, and the circulation pipe connected to the combustion chamber.
[0007] The combustion chamber includes an inner combustion cylinder connected to the air outlet of the burner. The inner combustion cylinder is used to supply the heat energy generated by the burner into the combustion chamber. The outer surface of the inner combustion cylinder is sealed with a combustion chamber, which is used to supply heat energy to the burner nozzle. The combustion chamber is rectangular. The air outlet of the combustion chamber is equipped with a burner nozzle, which is used to collect the heat energy and discharge it into the combustion tube. The burner nozzle is hollow and trapezoidal. The air outlet of the burner nozzle is equipped with a combustion tube, which is used to supply the heat energy in the combustion chamber into the heating chamber. The combustion tube is connected to the heating chamber.
[0008] A circulation port is provided at the top front end of the combustion chamber. The circulation port is used to return the heat energy used in the heating chamber to the combustion chamber. The circulation port is connected to the air outlet of the circulation pipe.
[0009] A distribution valve is installed on the circulation pipeline. The distribution valve is used to distribute the fluid to different equipment. The distribution valve is also used to guide the heat energy in the exhaust gas pipeline and return gas pipeline into the circulation pipeline. One of the air inlets of the distribution valve is connected to the exhaust end of the induced draft fan, and the other air inlet of the distribution valve is connected to the exhaust gas pipeline.
[0010] A first electric valve is installed between the distribution valve and the outlet end of the exhaust pipe. The first electric valve is used to control the opening and closing of the distribution valve and the exhaust pipe. The first electric valve is fixed on the exhaust pipe. A second electric valve is installed on each return pipe. The second electric valve is used to control the opening and closing of the distribution valve and the return pipe.
[0011] A spiral baffle is provided in the middle of the inner combustion cylinder. The spiral baffle is used to smoothly transport the hot air in the circulation pipe to the combustion chamber. One side of the spiral baffle is connected to the outer wall of the inner combustion cylinder, and the other side of the spiral baffle is connected to the inner wall of the combustion chamber. An air distribution plate is provided on the side of the combustion chamber near the burner. The air distribution plate is used to regulate and balance the hot air in the combustion chamber. The air distribution plate is connected to the inner wall of the combustion chamber.
[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0013] 1. The combustion chamber is heated by a burner, and the heat energy is then transferred to the heating chamber. The heat energy is then introduced into the cylinder through the ventilation pipes inside the chamber, which in turn heats the furnace body. When the induced draft fan is started, most of the lost heat energy is transported to the distribution valve through the return gas pipe and the exhaust gas pipe. Then, the distribution valve is connected to the combustion chamber through the circulation pipe, and the returned hot gas is supplied back into the combustion chamber for secondary use. This fully utilizes the heat energy in the combustion chamber and reduces heat loss and energy waste.
[0014] 2. The first electric valve is used to control the opening and closing of the distribution valve and the exhaust gas pipeline, and the second electric valve is used to control the opening and closing of the distribution valve and the return gas pipeline.
