Vertical carbonization device for automatic tar removal for carbon fiber production

Abstract

A vertical type carbonization device capable of automatically cleaning tar for carbon fiber production belongs to the field of carbon fiber production equipment. One side of a heating inner chamber is provided with a heating chamber, a driving roll is arranged in the heating inner chamber, a driven roll is arranged in the heating chamber, an absorption band takes the driving roll and the driven roll as the two ends to form a crawler structure, the absorption band goes through the joint position between the heating inner chamber and the heating chamber, and is in a cyclic motion; the gas outlet of the heating chamber is in a through connection with ultrasonic gas tar purification equipment through a gas recycling pipe line. The heating inner chambers of vertical type or inclined vertical type carbonization equipment both have circulation space which is beneficial for exhaustion of gas tar and occupation of tar-free gas, thus the gas tar generated during the production process will not be trapped in the heating area of the chamber to affect the product quality, and the protective gas and heat for production will not lose basically.

Description

Technical field [0001] The invention relates to a vertical carbonization device for automatically removing tar for carbon fiber production, which belongs to the field of carbon fiber production equipment. Background technique [0002] In the carbonization process of carbon fiber production, carbonization equipment is one of the core technologies and an important factor in the continuous production of carbon fiber and product quality. During the carbonization process, the large amount of tar gas generated will cause the carbon fiber to be burned or the hardening strength is low, which affects continuous production and causes the problem of low productivity. The main reason is that the equipment cannot meet the technical problem of tar gas removal required by the production process. The traditional horizontal carbonization equipment for carbon fiber production in China is basically difficult to completely change the technical problem of tar being completely removed. In the traditio...

Problems solved by technology

During the carbonization process, a large amount of tar gas will cause the carbon fiber to be burned or the hardened strength will be low, which will affect the continuous production and lead to the problem of low production capacity

The main reason is that the equipment cannot meet the technical problem of tar gas removal required by the production process. The traditional horizontal carbonization equipment for carbon fiber production in my country is basically difficult to completely change the technical problem of tar being completely removed. In the traditional horizontal heating zone indoor No matter what method is used to remove tar gas, it is impossible to completely protect the products in production. To remove a large amount of gas tar generated in production, the only way to remove the gas tar is to add air to supplement it. As a result, a large amount of protective gas and heat used for production are taken away, causing oxygen to enter the equipment room and a great waste, directly affecting normal production
