Abstract
The invention discloses an industrial molded coal and a manufacture process thereof, which uses soft coal with high moisture and high volatilization as raw material, coking coal, sodium humic acid and clay as caking agents. The method comprises the following steps: iron is removed from the raw material soft coal, and the raw material soft coal is crushed with the crushed particle less than or equal to 3mm; solid caking agents clay and coking coal are added to the crushed soft coal, and the liquid caking agent sodium humic acid is added to the crushed soft coal to be stirred and mixed; a storage stack is retted for aging for more than 24 hours; the aged coal is subjected to a secondary stirring; the aged coal is shaped at the pressure 10-30MPa; and the shaped coal is dried at a temperature lower than 90 DEG C to manufacture the molded coal. The industrial molded coal can be used for a fixed layer pressure coal gasification furnace.
Description
Technical field
The present invention relates to a kind of moulded coal, especially a kind of industrial shaping coal and production technique thereof.
Background technology
At present, social economy is in develop rapidly, the consumption of lump coal is increasing, along with the mechanical mining of coal is increasing, natural lump coal yield falls sharply, and the imbalance between supply and demand of lump coal becomes increasingly conspicuous, and price day by day goes up, the same place of production, the price of mixed coal of equal in quality (ungarbled raw coal) and lump coal differs more than 100 yuan.The existing large-scale Coal Gasification Technology of China has: shell Coal Gasification Technology, coal water slurry gasification technology and immovable bed pressing gas technology.Because the immovable bed pressing gasization must be made raw material with lump coal, this has just restricted immovable bed pressing gas The Application of Technology.The formed coal for gasification that China is present all is an immovable bed normal pressure gas stove moulded coal, does not also have immovable bed pressing gas stove moulded coal; And the feed coal that adopts all is hard coal, and the lower bituminous coal of market value also of no use is as the moulded coal raw material, production immovable bed pressing gas stove moulded coal.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of pattern production greatly, cheaply, be the industrial shaping coal and the production technique thereof of raw material with the bituminous coal of high moisture content and high-volatile.
For achieving the above object, the present invention has adopted following technical scheme:
