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 fibre oxidation oven.
Background technology
The main raw material(s) of producing carbon fiber is polyacrylonitrile fibril, undressed precursor is combustible material, be easy at normal temperatures burning, therefore 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 object of carbon, oxygen element enrichment and fiber sizing conventionally.
And existing carbon fibre oxidation oven is wrapped in a furnace chamber when carbon oxide fiber tow, if having a place to catch fire in the process of oxidation, whole carbon fibre tow also can blaze up.
Summary of the invention
The object of the invention is to solve the problems of the prior art, a kind of fire prevention layering of carbon fibre oxidation oven is provided.
Technical scheme of the present invention is: a kind of fire prevention layering of carbon fibre oxidation oven, body of heater top at oxidation furnace is provided with supply air duct and return airway, at described supply air duct, place is provided with fire nozzle, and a side of fire nozzle is provided with heater, is provided with some Ceng Si road in described furnace chamber.
Described supply air duct and return airway communicate with described silk road.
The both sides in described silk road are provided with stove end deflector roll.
The present invention is divided into some Ceng Si road by oxidation furnace, and every layer of carbon fibre tow is in independent Si Daonei operation, if there is combustion phenomena, 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 water, reaches the object of rapid fire extinguishing.
Accompanying drawing explanation
Fig. 1 is the front view of carbon fibre oxidation oven of the present invention
Fig. 2 is the top view of carbon fibre oxidation oven of the present invention.
The specific embodiment
For technological means, technical characterictic, goal of the invention and the technique effect that the present invention is realized is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As depicted in figs. 1 and 2, a kind of fire prevention layering of carbon fibre oxidation oven, two ends, top at the body of heater 1 of oxidation furnace are respectively arranged with supply air duct 2 and return airway 3, at described supply air duct, 2 places are provided with fire nozzle 4, a side at fire nozzle 4 is provided with heater 5, in the interior setting of furnace chamber 6 road 7 that haves three layers, supply air duct 2 and return airway 3 Yu Si roads 7 communicate.
As Fig. 1, the both sides in Si road 7 are provided with stove end deflector roll 8,81, and carbon fibre tow 9 enters from the left end silk road of furnace chamber 6 the stove end deflector roll 8 that then silk walks around right-hand member, enters 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 Ceng Si roads by oxidation furnace, and every layer of carbon fibre tow, in independent Si Daonei operation, if there is combustion phenomena, 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 water, reaches the object of rapid fire extinguishing.
Be only preferred embodiment of the present invention in sum, be not used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application the scope of the claims change and modify, all should belong to technology category of the present invention.
