A kind of activated carbon fiber low temperature pre-oxidation equipment

Abstract

The invention discloses an activated carbon fiber low-temperature pre-oxygenation device, which belongs to the technical field of carbon fiber manufacturing and includes a carbonization bin, a carbon fiber bundle, and a gas transportation pipeline. The gas transportation pipeline includes a gas transportation pipe and a waste gas transportation pipe. Pipe and waste gas transport pipe, the side of the gas transport pipe close to the gas transport pipe is provided with a hot blower, and the waste gas transport pipe passes through the gas transport pipe. The movement direction of the carbon fiber bundles in the present invention is opposite to the flow direction of the air in the carbonization chamber. A carbonization chamber and a hot air fan are provided to realize multi-temperature pre-oxygenation treatment, which saves manufacturing costs while rationally utilizing energy. Part of it passes through the gas transportation pipe, and the blown cold air will exchange heat with the exhausted exhaust gas during the flow process, which makes reasonable use of energy. The exhaust gas discharge pipe passes through the hot water tank and is connected to the exhaust gas treatment chamber. The waste heat of the exhausted exhaust gas is given to the The water temperature in the hot water tank is heated, and the energy is used rationally.

Description

technical field [0001] The invention relates to low-temperature pre-oxygenation equipment, in particular to low-temperature pre-oxygenation equipment for activated carbon fibers, which belongs to the technical field of carbon fiber processing. Background technique [0002] In recent years, under the promotion of relevant national ministries and commissions, my country's carbon fiber industry has made major breakthroughs in industrialization and large-scale development. With the momentum of accelerated development, carbon fiber industry clusters mainly in Shandong, Jiangsu and Jilin have been initially formed, and a number of carbon fiber production backbone enterprises and a group of carbon fiber composite materials and product enterprises have been cultivated. According to statistics, from 2010 to 2016 During the year, my country's carbon fiber production capacity increased from 6,445 tons to 23,810 tons, an increase of nearly four times. At present, all carbon fibers produce...

Problems solved by technology

[0003] The carbon fiber manufacturing process requires low temperature in the ocean, low temperature pre-oxidation requires extremely high temperature, and requires several greenhouses with gradually increasing temperature. The existing high temperature carbonization device has poor heat preservation effect and serious energy consumption, resulting in a great waste of resources.
