Energy-saving carbonization furnace and use method thereof

Abstract

The invention belongs to the technical field of carbonization furnaces, and particularly relates to an energy-saving carbonization furnace which comprises a carbonization furnace assembly, a pressurizing assembly and a storage assembly, wherein the carbonization furnace assembly is connected with the pressurizing assembly through a pipeline, and the pressurizing assembly is connected with the storage assembly through a pipeline. According to the carbonization furnace, liquefaction of the combustible gas is achieved; a flow control structure is arranged, so that liquefaction of different gases under different pressure intensities can be distinguished conveniently, and separate storage is facilitated; the storage assembly is divided into three different storage areas used for storing three different liquefied combustible gases, and thus fuel adding in the drying stage of the carbonization furnace is avoided. The invention further provides a using method of the energy-saving carbonization furnace, the operation is convenient and simple and easy to understand, an operator can master the energy-saving carbonization furnace skillfully through simple training, the operation is simple, each step can work independently, and the operability of the carbonization furnace is improved.

Description

technical field [0001] The invention belongs to the technical field of carbonization furnaces, and in particular relates to an energy-saving carbonization furnace and a using method thereof. Background technique [0002] During the production process of carbon fiber, the thermal decomposition reaction of pre-oxidized fiber occurs in the low-temperature carbonization furnace, and a large amount of waste gas, tar and carbon powder are produced. As the production time goes by, the waste gas enters the incinerator under the action of the exhaust fan for incineration. , However, under the action of tar, carbon powder will gather on the inner wall of the low temperature carbonization furnace, especially the top of the furnace to form deposits. After this part of the deposit reaches a certain thickness, on the one hand, it will affect the uniformity of the original temperature field in the furnace; on the other hand, if it falls off, it will adhere to the surface of the running tow...

Problems solved by technology

[0007] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an energy-saving carbonization furnace, which is used to solve the time-consuming and labor-intensive assembly and maintenance of the prior art, low efficiency, unstable connection, and low structural strength; When the furnace is working, the gas generated is not only supplied to the carbonization furnace for heating, but also a large amount of gas is wasted and volatilized directly into the air, which will cause the workers in the factory to lack oxygen; the carbonization furnace needs to add fuel to the carbonization furnace before carbonization. The materials are dried, the steps are cumbersome, not energy-saving, etc. The present invention also provides a method for using an energy-saving carbonization furnace, which is easy to operate, simple and easy to understand, and the operator can master it after simple training; the operation Simple, each step can also work independently, improving the operability of the present invention
