In the present invention, pyrolysis and vaporization with a sulfurized bed can obtain coal gas which is free of contaminants such as coal tar and converted by coal. The pyrolysis bed can be used to vaporize semi-finished coke products and burn them sufficiently. The effect of the present invention is that the vaporization rate of coal is high, and contaminants such as coal tar are not formed in the process of vaporization, and applied to various types of large, medium and small vaporization devices, and the amount of gas generated within a unit time There is a large range of adjustment.
Description
本発明は、石炭でガスを形成する多重気化装置に関し、具体的に、循環硫化ベッドと熱分解ベッドにより硫化熱分解気化を順にする気化炉に関するものであり、石炭の気化に用いられ、石炭気化装置の分野に属する。 The present invention relates to a multi-gasification apparatus for forming gas with coal, and more particularly, to a vaporization furnace for performing sulfidation pyrolysis vaporization sequentially by a circulating sulfidation bed and a pyrolysis bed, which is used for vaporization of coal, Belongs to the field of equipment.
工業の経済の迅速な発展に伴い、石炭は工業の生産の過程において熱を獲得する原料としてなければならない原料である。しかしながら、石炭を直接に燃焼させることにより環境の汚染が発生するので、最近、政府は石炭を直接に燃やすことを禁止する色々な規定を発布した。石炭を石炭ガスに変換させ、きれいであり汚染がない石炭ガスを燃焼させることにより熱を獲得するために、人々は石炭を石炭ガスに変換させる色々な気化炉を設計した。例えば、石炭ガスを生成するため固定ベッド気化炉、循環硫化ベッド気化炉などの気化炉を発明したことにより、石炭の燃焼による環境の汚染を低減することができる。従来の色々な気化炉を研究してみると、各気化炉は色々な欠点を有している。例えば、固定ベッド気化炉は、石炭の変換率と熱の効率が高い利点を有しているが、石炭ガス中に大量のコールタール等の汚染物が含まれている欠点を有している。循環硫化ベッド気化炉はコールタール等の汚染物が含まれていない石炭ガスを製造することができるが、石炭の熱使用率が低く、炭殻に大量のコークス半製品が含まれているので、コークス半製品が含まれている炭殻を所定の場所に運んで再び燃焼させる必要がある。例えば発電所に運んで発電の原料として用いることができる。それにより石炭の使用率が低下し、運輸、人工などによるコストが増加する。したがって、人々は、石炭を石炭ガスに変換させる効率を向上させるとともにきれいな石炭ガスを獲得することができる新しい石炭ガス生成装置を提供することを望んでいる。 With the rapid development of the industrial economy, coal is a raw material that must be used as a raw material to gain heat in the industrial production process. However, as burning coal directly causes environmental pollution, the government has recently issued various provisions prohibiting direct burning of coal. In order to convert heat to coal gas and gain heat by burning clean and uncontaminated coal gas, people have designed various vaporization furnaces that convert coal to coal gas. For example, by devising a vaporization furnace such as a fixed bed vaporization furnace or a circulating sulfurized bed vaporization furnace to generate coal gas, environmental pollution due to coal combustion can be reduced. When studying various conventional vaporization furnaces, each vaporization furnace has various drawbacks. For example, fixed bed vaporization furnaces have the advantage of high coal conversion and heat efficiency, but have the disadvantage that coal gas contains large amounts of contaminants such as coal tar. The circulating sulfurized bed vaporization furnace can produce coal gas free of contaminants such as coal tar, but the heat utilization rate of coal is low, and the coal shell contains a large amount of semi-finished coke products. It is necessary to carry the carbon shells containing coke semi-finished products to a predetermined place and burn them again. For example, it can be carried to a power plant and used as a raw material for power generation. As a result, the rate of use of coal decreases, and costs for transportation and man-hours increase. Thus, people want to provide a new coal gas generator that can improve the efficiency of converting coal to coal gas and obtain clean coal gas.
本発明の目的は、循環硫化ベッドと熱分解ベッドの組合せにより気化をする方法を提供し、循環硫化ベッドと熱分解ベッドの組合せによって燃焼気化をすることにより、石炭の変換率を向上させ、石炭ガス中の主要な汚染物を除去することにある。 The object of the present invention is to provide a method of vaporization by combination of circulating sulfurization bed and pyrolysis bed, and by improving combustion conversion rate by combination of circulating sulfurization bed and pyrolysis bed to improve the conversion rate of coal, coal It is about removing the major pollutants in the gas.
