Abstract
The invention discloses fireproof layers of a carbon fiber oxidation furnace. There is provided with an air supply channel and an air return channel at the top of the oxidation furnace body, wherein the air supply channel has a firefighting nozzle which is equipped with a heater on one side. The furnace chamber is equipped with several layers of fiber passages inside. The oxidation furnace is divided into several layers of fiber passages in this invention, and each layer of carbon fiber bundles runs in a separate fiber passage, so that the fibers in other layers of fiber channels will not be affected in case of combustion, and the fire water, after opening, will be blown into the fiber passages by a fan to achieve the purpose of rapid fire extinguishing.
Description
Technical field
The present invention relates to a kind of oxidation furnace, relate in particular to a kind of fire prevention layering of carbon fiber oxidation furnace.
Background technology
The main raw material(s) of producing carbon fiber is a polyacrylonitrile fibril; Undressed precursor is a combustible material; Be easy to burning at normal temperatures; So precursor must be introduced into oxidation furnace and carries out pre-oxidation treatment before high temperature cabonization, pre-oxidation treatment is the process of an oxidation, dehydrogenation, denitrogenation, cyclisation, and this process reaches the purpose of carbon, oxygen element enrichment and fiber typing usually.
And existing carbon fiber oxidation furnace is wrapped in when the carbon oxide fiber tow in the furnace chamber, if there is a place to catch fire, then whole carbon fibre tow also can blaze up in the process of oxidation.
Summary of the invention
The objective of the invention is to solve the problems of the prior art, a kind of fire prevention layering of carbon fiber oxidation furnace is provided.
Technical scheme of the present invention is: a kind of fire prevention layering of carbon fiber oxidation furnace; Body of heater top at oxidation furnace is provided with supply air duct and return airway; The place is provided with fire nozzle at said supply air duct, and a side of fire nozzle is equipped with heater, is provided with several layers silk road in the said furnace chamber.
Said supply air duct and return airway communicate with said silk road.
The both sides in said silk road are provided with stove end deflector roll.
The present invention is divided into several layers silk road with oxidation furnace, and every layer of carbon fibre tow is in independent Si Daonei operation, if combustion phenomena takes place; Can not bring disaster to the silk in remainder layer silk road; And fire water is after opening, and blower fan can blow into Si Daonei to water, reaches the purpose of rapid fire extinguishing.
Description of drawings
Fig. 1 is the front view of carbon fiber oxidation furnace of the present invention
Fig. 2 is the vertical view of carbon fiber oxidation furnace of the present invention.
The specific embodiment
Understand for technological means, technical characterictic, goal of the invention and the technique effect that the present invention is realized is easy to understand,, further set forth the present invention below in conjunction with concrete diagram.
As depicted in figs. 1 and 2; A kind of fire prevention layering of carbon fiber oxidation furnace; Be respectively arranged with supply air duct 2 and return airway 3 at the two ends, top of the body of heater 1 of oxidation furnace, 2 places are provided with fire nozzle 4 at said supply air duct, in a side of fire nozzle 4 heater 5 are installed; The road 7 that haves three layers is set in furnace chamber 6, and supply air duct 2 communicates with silk road 7 with return airway 3.
Like Fig. 1, be provided with stove end deflector roll 8,81 in the both sides in silk road 7, carbon fibre tow 9 is gone into the stove end deflector roll 8 that silk is walked around right-hand member then from the left end silk road of furnace chamber 6, get into the Si Daonei of last layer, walks around the stove end deflector roll 81 of left end, from the right-hand member wire vent of furnace chamber 6.
The present invention is divided into 3 layers of silk road with oxidation furnace, and every layer of carbon fibre tow if combustion phenomena takes place, can not bring disaster to the silk in remainder layer silk road in independent Si Daonei operation, and fire water is after opening, and blower fan can blow into Si Daonei to water, reaches the purpose of rapid fire extinguishing.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should belong to technological category of the present invention.
