Green continuous carbonization device for producing carbon fibers

Abstract

The invention discloses a green continuous carbonization device for producing carbon fibers, which comprises an annular cylinder with a combustion chamber, an outer box and a bottom plate, a base is symmetrically and fixedly arranged between the outer box and the bottom plate, an air inlet pipe is inserted in the outer side wall of the outer box in a penetrating manner, and a connecting pipe is fixedly arranged on the part, in the outer box, of the air inlet pipe. The side wall of the outer box is fixedly connected with a layering plate in a sealed mode, the layering plate divides the inner space of the outer box into a treatment space and a liquid storage space, the end, away from the air inlet pipe, of the connecting pipe is fixedly connected with the layering plate, the layering plate is communicated with the connecting pipe and provided with an air inlet hole, and the air inlet hole is communicated with the liquid storage space. A heat dissipation and dust removal structure is connected in the liquid storage space, and an anti-blocking structure is arranged in the treatment space. The heat exchanger has the advantages that the heat exchanger effectively and fully exchanges heat with liquid water, so that when gas is exhausted through the gas outlet pipe, the external environment temperature cannot be influenced, and a good processing environment is guaranteed for processing workers.

technical field [0001] The invention relates to the technical field of carbon fiber carbonization, in particular to a green continuous carbonization device for producing carbon fiber. Background technique [0002] Carbon fiber is a new type of non-metallic material with a series of excellent properties such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, creep resistance, low thermal expansion, high electrical and thermal conductivity, self-lubricating, etc. Softness, knitting, and weaving are widely used in cutting-edge fields such as aerospace, national defense and military, as well as civil industries such as advanced textiles, sporting goods, and medical equipment. [0003] In the prior art, high-modulus carbon fibers are obtained by graphitizing fibers in an inert atmosphere at 2000-3000° C.

Problems solved by technology

[0003] In the prior art, the fibers are graphitized in an inert atmosphere at 2000-3000°C to obtain high-modulus carbon fibers. Therefore, in the continuous carbonization process, high-temperature combustion is required, and harmful smoke and dust need to be discharged, which is easy to pollute the environment. , after retrieval, the Chinese Authorized Patent Publication No. CN108950741B discloses a continuous carbonization device for producing carbon fibers, and its structure includes a continuous carbonization furnace, a thermometer, a hook, a furnace cover, a handle, a foot, and an electric control box; the continuous carbonization furnace consists of a furnace Body, power mechanism, gas circulation mechanism, smoke treatment chamber, smoke exhaust mechanism, gas delivery pipe, high temperature combustion chamber, liquid discharge mechanism, liquid delivery mechanism, liquid one-way delivery pipeline, liquid recovery room, the present invention adopts power mechanism to drive The smoke exhaust mechanism enters the soot in the high-temperature combustion chamber into the soot treatment room, and drives the liquid one-way delivery pipeline to inject the water in the liquid recovery room into the soot treatment room through the liquid delivery mechanism. After analysis, this prior art can solve the problem of absorbing harmful soot However, in actual use, its internal structure is complex and requires multiple pulleys for linkage and coordination. On the one hand, it is troublesome to assemble, and on the other hand, it causes large energy loss during the transmission process, which is not conducive to environmental protection. At the same time, during use , because the high-temperature combustion chamber and the gas circulation structure are in the same equipment during the high-temperature carbonization process, when the gas is processed after combustion, it cannot ensure that the temperature is in a normal state when the gas is discharged, so that the temperature of the external environment will increase after the high-temperature gas is discharged. , which is not conducive to processing workers to perform processing operations. Based on this, the present invention designs a green continuous carbonization device for producing carbon fibers
