Continuous carbon powder production system

Abstract

The invention relates to a continuous carbon powder production system comprising a gasifier, a spray tower, a cooling tower group, a carbonization machine, a feeding machine and a discharging machine. A gas outlet of the gasifier is communicated with a gas inlet of the spray tower, a gas outlet of the spray tower is communicated with a gas inlet of the cooling tower group, and a gas outlet of the cooling tower group is communicated with a gas inlet of a burner of the carbonization machine; the feeding machine corresponds to a feeding port of the carbonization machine, the discharging machine corresponds to a discharge port of the carbonization machine, and an exhaust port of the carbonization machine is connected with the gas inlet of the spray tower through a gas return pipe. In the continuous carbon powder production system, the gasifier produces combustible gas which is used as the heat source of carbonization, then flue gas produced during carbonization of the carbonization machine is sprayed, cooled and purified and subsequently conveyed to the carbonization machine for secondary combustion, the process is repeated, and the heat generated by the system is utilized to burn the gas so that the effects of energy saving and environment protection are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of carbon powder production equipment, and in particular relates to a continuous carbon powder production system. Background technique: [0002] Charcoal powder is a charcoal powder made from crop stalks and forestry residues. Today, charcoal powder is used in many fields such as industry, agriculture, medicine, and households. Charcoal powder can be used for metallurgy, medicine, and soil improvement. It can be used in households to absorb formaldehyde to remove harmful gases, dehumidify, and deodorize. [0003] At present, the production process of charcoal powder is mainly to add straw and forestry residues into the carbonization machine 5, heat and dry them, and then carbonize them to form charcoal powder. However, the heating energy used in the production of existing charcoal powder is generally conventional energy. , when heating, drying and carbonizing straw and forestry residues, it will be accom...

Problems solved by technology

[0003] At present, the production process of charcoal powder is mainly to add straw and forestry residues into the carbonization machine 5, heat and dry them, and then carbonize them to form charcoal powder. The heating energy used in the production of some charcoal powder is generally conventional energy. When heating, drying and carbonizing straw and forestry residues, there will be a lot of smoke, which also contains a lot of heat and energy. Gas that can undergo secondary combustion, but the existing charcoal powder production process directly discharges the flue gas to the atmosphere, causing a lot of energy waste and also polluting the atmosphere
