Abstract
The utility model relates to a high-temperature carbide furnace with a deoxidization system, which belongs to the field of carbon fiber production equipment. The utility model is provided with a high-temperature carbide furnace; the inlet of the high-temperature carbide furnace is connected with the outlet of the deoxidization system by a flange; the upper end of the shell of the deoxidization system is provided with a waste gas discharge port; the left end of the upper side and the left end of the lower side of the deoxidization system are provided with nitrogen inlets; the cavity of the deoxidization system is provided with an infrared heater; the inlet of the deoxidization system is provided with a rotating roller. When the high-temperature carbide furnace works, the content of oxygen-containing gas molecule which is brought into a hearth by the fiber is reduced to be less than the 5 percent of the original, which effectively reduces the dew point of the inlet temperature area of the high-temperature furnace, basically eliminates the corrosion of the muffle furnace in the inlet temperature area of the high-temperature furnace and integrally prolongs the service life of the high-temperature furnace.
Description
Technical field
The utility model is a kind of carbon fiber production equipment, particularly a kind of high temperature carbonization furnace with pre-deaerating plant.
Background technology
As everyone knows, during carbon fiber is produced, be used for nucleus equipment--the high temperature carbonization furnace of fiber high temperature carbonization, under 900-2500 ℃ temperature, carbon fiber heat-treated, finish the last conversion and the typing of fibre structure.Belong to a kind of of Muffle furnace on its structure, a rectangle or circular seal chamber are arranged, make with extraordinary graphite material.Because fiber after low-temperature carbonization, enters the high temperature cabonization stokehold, (about 0.5-4min) is exposed in the air for some time, thereby can absorb some airborne H
2O, CO
2Deng the oxygen-containing gas molecule, and the fiber of operation has certain speed, though also be provided with the sealing gland of labyrinth type or other form, but fibre bundle carry suction-operated with fiber self secretly, still many oxygen-containing gas molecules can be brought in the stove, thereby be corroded the not body of heater of porch of burner hearth horse, particularly corrode the heater element of making by special material, compare with the heater element of the same race of other warm area, shorten service life greatly.The general labyrinth type or the sealing gland of other form only can be removed the oxygen-containing gas molecule of carrying secretly in the fibre bundle, and powerless to the oxygen-containing gas molecule of fibrous inside absorption.
Summary of the invention
In order to solve the deficiency of above-mentioned existing equipment technology, the utility model provides a kind of mitigate corrosion, the extraordinary high temperature furnace that increases the service life.
The utility model adopts following technical solution: be provided with high temperature carbonization furnace, the inlet of high temperature carbonization furnace links to each other with the outlet of deaerating plant through flange, deaerating plant housing upper end has Waste gas outlet, the left end of deaerating plant upside and downside has a nitrogen and feeds the hole, in the cavity of deaerating plant infrared heater is installed, the deaerating plant arrival end is provided with the rotation roller.
The beneficial effects of the utility model are: the burden that has alleviated high temperature furnace inlet air seal set greatly, effectively reduced the dew point of high temperature furnace inlet warm area, the oxygen-containing gas molecule is eliminated substantially to the corrosion of high temperature furnace inlet warm area Muffle furnace body, the heater element made by special material of this warm area has prolonged 48% service life simultaneously, has prolonged the service life of high temperature furnace on the whole greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. nitrogen feed the hole among the figure, 2. infrared heater, 3. Waste gas outlet, 4. flange, 5. high temperature carbonization furnace, 6. nitrogen feeding hole, 7. rotation roller.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1, the inlet of high temperature carbonization furnace 5 links to each other with the outlet of deaerating plant through flange 4, deaerating plant housing upper end has Waste gas outlet 3, the left end of deaerating plant upside and downside has nitrogen and feeds hole 6 and nitrogen feeding hole 1, infrared heater 2 is installed in the cavity of deaerating plant, and the deaerating plant arrival end is provided with and rotates roller 7.After fiber enters pre-deaerating plant, be heated to 100 ℃-300 ℃, simultaneously, feed high pure nitrogen or the helium that multichannel heats from the device upper and lower respectively, with the H of fibre bundle and fibrous inside discharge against the fiber approach axis by infrared ray
2O, CO
2Deng oxygen-containing gas molecule (particularly the oxygen-containing gas molecule of fibrous inside absorption does not heat and can't remove), take away from Waste gas outlet and this device fiber entry, thereby alleviated the enter the mouth burden of air seal set of high temperature furnace greatly.
Have the extraordinary high temperature carbonization furnace of the pre-deaerating plant of the fiber degree of depth, bringing oxygen-containing gas molecule in the burner hearth into by fiber in running reduces to original below 5%, effectively reduced the dew point of high temperature furnace inlet warm area, corrosion to high temperature furnace inlet warm area Muffle furnace body is eliminated substantially, the heater element that this warm area is made by special material has prolonged 48% service life, has prolonged the service life of high temperature furnace on the whole greatly.The pre-deaerating plant volume of the degree of depth is little, simple in structure simultaneously, is easy to make, and is easy to maintenance.
