Abstract
An effective energy conservation apparatus apply to producing carbon fiber through heating gas to make it used circulated, it relates to the art of carbon fiber manufacture. Its characteristic is that there is piping for gas recycling in the rectangle or round box, one side of the box is connected to a gas purifier whose other side is connected to the air outlet of the equipment for carbon fiber production, and the other side of the box is joined to the air inlet of the equipment for carbon production. The implementing way is that the waste gas with high quantity of heat discharged by equipment becomes useful gas through gas purifier, and then the useful gas is transported into the equipment again, so it realizes the recycling use of gas. This can save heat of gas, promote economic returns and protect the environment.
Description
Technical field the present invention relates to carbon fiber and makes the field, a kind ofly produces the heated air that carbon fiber uses and recycles efficient energy-saving device.
The manufacturing of background technology carbon fiber is the multidisciplinary intersection of technology, complexity not only, also has many details technical problems to settle one by one in the production that realizes industrialization.If carbon fiber or pre-oxidized fibers are implemented to industrialization from the laboratory, should just step the first step.The heat treated of specialty fibers such as carbon fiber and pre-oxidized fibers all needs a large amount of electric power energy consumption, and wherein the gas circulation that must use has also been taken away a large amount of heats.A large amount of energy resource consumptions has not only increased product cost, and has caused not right a large amount of energy wastes.So solve the too high and unnecessary a large amount of energy waste of cost in the carbon fiber industrialization, be the problem that we constantly explore, study.
Summary of the invention the purpose of this invention is to provide a kind ofly to be produced the heated air that carbon fiber uses and recycles efficient energy-saving device, mainly includes casing, outer case, internal box, outer case heat-insulation layer, gas circulation pipeline, gas purifier, clarifier heat-insulation layer, casing inlet pipe connection road, the casing connecting pipe of giving vent to anger and forms; Its casing is rectangle or circle, be by outer case, internal box and heat-insulation layer are formed, in outer case, be set with internal box, be provided with heat-insulation layer in the isolation slit between internal box and outer case, load heatproof in the heat-insulation layer, insulation material, be provided with the gas circulation pipeline in the casing, casing one side is provided with casing and connects the casing admission line that is connected, the casing admission line other end is connected with gas purifier is through, gas purification body one side is connected with the inlet pipe connection road is through, gas purifier is wrapped with heatproof, the heat-insulation layer of insulation, the inlet pipe connection road is connected with carbon fiber production equipment gas outlet, the casing opposite side is provided with the casing that is connected with the casing connecting pipe of giving vent to anger, and the casing connecting pipe of giving vent to anger is connected with carbon fiber production equipment air inlet.Casing, circulating line, admission line, inlet pipe connection road, the connecting pipe of giving vent to anger all adopt high-class stainless steel or heatproof, resistant material to make, and the model that gas purifier selects for use turnover tolerance to be complementary is with it purchased.
The high heat waste gas body of discharging through the gas outlet in the carbon fiber production equipment, enter in the gas purifier along the inlet pipe connection road that connects gas purifier, high heat waste gas body is after gas purifier purifies, change into and can be used for the gas that the carbon fiber production equipment uses, and enter in the casing along admission line, gas is through circulating line, the casing connecting pipe of giving vent to anger, the carbon fiber production equipment air inlet that connects to connecting with it and in the access arrangement, thus the waste gas body that produces in the carbon fiber production equipment formed, change into available gas through the gas purifier purification, be delivered into and be produced as the waste gas body in the equipment again, after purifying, gas purifier changes into the cyclic process of gas more again.
The gas of producing the required usefulness of carbon fiber equipment must could use after purifying, remove the assorted dirt that is unfavorable for producing carbon fiber in the air.The carbon fiber manufacturing technique requirent; Not only the air of access arrangement must remove assorted dirt through purification and also will be heated into different high-temperature gases.According to traditional gas using method be air is delivered into equipment after, heat just can be assigned in the equipment and use, become waste gas after gas is employed and be discharged from outside the equipment.All needing to consume a large amount of electric energy heating treatment process no matter produce carbon fiber, pre-oxidized fibers or specialty fibers etc., is that the different process according to different fibers adopts different temperatures, the heating of gradient hot blast, oxidation furnaces equally also needs design temperature, gradient-heated in processing procedure.
In whole process procedure, will not have the whole emptyings of hot blast of assorted dirt for the needs that guarantee the product oxygen uptake and have a design temperature.Only with the hot blast of institute's emptying by efficient energy-saving device load senior filtration, burning processing device continues to reuse in the equipment of sending back to, the required oxygen of product replenishes the supply from blast heater, the heat in the equipment can not drained like this, the effective temperature in the eternal maintenance equipment continues to use.Heater in the equipment startup heating function that just can stop consumes a large amount of electric energy and contaminated environment like this.
Principle of the present invention be with a large amount of hot blasts of institute's emptying by heat exchanger load senior filtration, burning processing device reclaims, and continues to reuse in the equipment of sending back to, and efficient temperature is controlled within the scope of application all the time, be unlikely to leak and waste energy.The required new fresh oxygen of product can be satisfied the demand from blast heater.
The scope of application of the present invention is the scope that is useful for the required gas heat treated of production equipment such as carbon fiber, pre-oxidized fibers, specialty fibers.
Advantage is to keep the gas temperature that heated and energy-efficient more than 50%; Reduce product cost, increase economic efficiency; Environmental protection, the gas that will not have assorted dirt drain in the air and contaminated environment.
