Plasma high temperature carbon conversion gas film reactor

Abstract

The invention relates to a plasma high temperature carbon conversion gas film reactor which comprises the following parts which are connected according to the following sequence: an upper flange, an outer cylinder, a temperature measuring element, an air inlet flange, an air inlet pipe, a lower flange, a water-cooled cylinder wall, an inner cylinder wall, an air inlet and a baffle plate, wherein the upper flange, the outer cylinder, the inner cylinder wall and the lower flange form a cavity, the rest parts are sequentially connected with the cavity, the angle of the inner wall of the reactor is designed according to the divergence angle of an airflow formed by mixing plasma and lysate, a series of small holes are punched on the specific diameter and the specific height of a side wall and used for introducing a protective gas, and meanwhile, a water-cooled side wall is arranged at a proper height, thereby preventing the side wall from being ablated due to excess temperature, greatly reducing the damage of the high-temperature gas to the reactor, avoiding a serious coking condition of the side wall, effectively keeping the temperature and enabling the reactor to stably operate for along time.

Description

technical field [0001] The invention relates to a carbon conversion reaction device in a high-temperature environment, in particular to a plasma high-temperature carbon conversion gas film reactor. Background technique [0002] In recent years, with the continuous development of plasma physics, plasma technology has been widely used in materials, energy, information, chemical industry, physics, medicine and other fields. The chemical activity and high enthalpy of plasma make many traditional methods impossible to achieve. It became possible, which led to a series of process innovations and technological advancements, coal cracking or gasification coal is one of them, and the process of using plasma cracking coal to produce acetylene has also been reported in large numbers in the literature: Shang Shuyong, Yin Yongxiang, Li Juan, He Fangfang, Dai Xiaoyan. Thermal plasma pyrolysis of natural gas and coal to acetylene ethylene [J]. Chemical Journal, 2004, (08)). The method desc...
