Abstract
The utility model discloses a tar removal device of a carbide furnace for carbon fiber production, belonging to the field of carbon fiber production equipment. A tar removal device is arranged above a hearth; the tar removal device consists of an adsorption band and a gas purifying circulation device, wherein the adsorption band is composed of mutually connected chains or laths; certain gaps are formed between the laths to form an adsorption band with gaps; the gas purifying circulation device comprises a gas extraction hood, a gas extraction pump, a gas purifying structure and a gas feed port; the gas extraction hood is arranged above the adsorption band and connected with an inlet of the gas purifying structure through a pipeline; an outlet of the gas purifying structure is connected with a gas feed port formed in the hearth through a pipeline. By arranging the adsorption band and the gas extraction system in the hearth, the tar can be effectively adsorbed and does not drop easily; meanwhile, the adsorption band with accumulated tar can be transferred out of the furnace for cleaning, thus continuous production of carbon fiber is not influenced, and the tar drop and consequent breakage of the carbon fiber are avoided.
Description
Technical field
The utility model relates to carbon fiber and produces the tar removal device with carbide furnace, and it belongs to carbon fibre producing facility field.
Background technology
Producing carbon fiber equipment its carbonizing apparatus in carbonisation is one of core technology, be related to the serialization production of carbon fiber and the key factor of product quality, in producing the process of carbon fiber, when carbon fiber material carries out carbonization treatment under the temperature conditions of 300-600 ℃, produce a large amount of tar, after being attached to the tar assembly on hearth wall, can be shed to again just on the filament of carbonization treatment, therefore due at high temperature easily burning of tar, in the high temperature cabonization processing meeting of postorder, cause fracture of wire because of the burning of tar.The carbonizing apparatus of China's traditional mode of production carbon fiber is difficult to thoroughly change the technical barrier that tar is thoroughly removed substantially; no matter adopt any removing tar gas mode; all cannot intactly protect the product in production; and a large amount of gas tar that removing produces in producing; also only have employing to take gas tar away adds air to supplement simultaneously; and when taking tar away, also caused in a large number for the production of protective gas and heat be pumped; caused in canyon and entered oxygen and waste greatly, directly affected normal production or therefore can not produce.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon fiber to produce the tar removal device with carbide furnace, and it can effectively prevent coming off of tar and remove tar, thereby has realized the continuous production of carbon fiber.
The purpose of this utility model is such realization: carbide furnace comprises burner hearth, furnace lining, heat-insulation layer, heater, is provided with tar removal device above burner hearth, and tar removal device is comprised of gas purification circular device and adsorption band; Gas purification circular device comprises draft hood, aspiration pump, gas purification structure, air supply opening; Draft hood is placed in adsorption band top, and draft hood is connected with the entrance of gas purification structure by pipeline, and the outlet of gas purification structure is connected with the air supply opening being located on burner hearth by pipeline; Adsorption band is to consist of interconnective chain or lath, forms and is with apertured adsorption band; Adsorption band is packaged type, and adsorption band two ends are outside furnace lining extends to stove; Furnace lining opening adopts nitrogen or inert gas sealing protection.Described draft hood is unsettled above adsorption band, and the cover mouth of draft hood is towards adsorption band, and covers the adsorption band in burner hearth, and the cover mouth of draft hood and the gap of adsorption band are 1-5cm.The thickness of described adsorption band is 7-14mm, and the chain or the gap between lath that form adsorption band are 1-1.4 mm.Described gas purification structure is sealing type cistern, and entrance is positioned at water tank bottom, and outlet is positioned at water tank upper, and the gas that aspiration pump extracts enters water tank by entrance, after water cooling purifies, from outlet, is delivered in burner hearth.
Feature of the present utility model is: adsorption band and extract system are set in burner hearth, tar adsorption and difficult drop-off effectively, simultaneously can also have the adsorption band of tar to shift out stove place to clean by accumulating, neither can affect the continuous production of carbon fiber, there will not be again tar to come off and cause the disconnection of carbon fiber, so this carbide furnace can be produced the carbon fiber wire of all size.
