Description
One, technical field
The present invention relates to coal chemical technology, especially, relate to coal dust gas and carry.
Two, background technology
Coal gasification is the cleaning and efficient tap and the gordian technique of utilizing of coal.Air flow bed pressurized gasification is the New type coal parallel type gasification technology growing up nearest decades, vaporized chemical and coal dust or coal slurry enter vaporizing chamber through nozzle, pyrolysis, burning and the gasification reaction of coal almost carry out simultaneously, high temperature has guaranteed high efficiency gasification, and the mineral matter in coal leaves gasification furnace after becoming slag.Compared with other gasification technologies, pressurized entrained-bed gasification temperature is high, processing capacity large, gas effective constituent is high, gasification efficiency is high, is the current developing direction of one of state-of-the-art Coal Gasification Technology, future coal synthesis type gasification technology in the world.
Pressurized entrained-bed vapor pressure is higher, and dry coal powder pressure gasifying adopts high pressure nitrogen or CO
2dry powder is close manages defeatedly mutually, enters gasification furnace by gasification nozzle, has that coal adaptability is wide, consumption of raw materials is low, efficiency of carbon con version is high, cold gas efficiency is high, and gasification furnace structure is with technical advantages such as slag anti-slag, life-span are long.Under gasification furnace conditioned disjunction coal same case, than coal water slurry gasification technology joint oxygen 16～21%, economize on coal 2～4%, effectively gas composition is high 6～10 percentage points.But manage mutually defeated fine breeze because excess pressure is close and can cause that powder flowing characteristic changes, thereby cause difficulty of transportation, affect device smooth operation, therefore dry powder pressurized gasification can only be not more than 4.0Mpa at present, and pressure is higher, gasification furnace stable operation difficulty is larger; In addition manage mutually defeatedly due to high densification, need to be dried coal dust moisture and be less than 1%, need larger energy consumption for drying; Synthesis gas also needs to continue compression pressurization and could be used for downstream synthesis technique in addition.Be pressed into from height, dry powder pressurized gasification system energy consumption is higher than water coal slurry pressure gasification.
For a difficult problem that solves pressurization of dry pulverized coal and carry continuously, first Texaco company has created coal water slurry gasification technique.With the comparison of dry pulverized coal feeding manner, the sharpest edges that coal water slurry charging has are to be easy to pressurization, and the operating pressure grade of commercialization device generally, between 2.6～8.5MPa, is convenient to meet multiple downstream process gaseous tension demand.High-pressure gasified can be not only that the downstream processes such as methyl alcohol, acetic acid are saved intermediate compression operation, has also reduced energy consumption; Feed coal transportation, slurrying, to be pumped into furnace system simpler than dried coal powder pressurized gasification, safety and easily control, reduced investment; Gasification furnace structure is simple, is lining of fire brick, easily manufactured, cost is low.But the evaporation of nearly 40% water need to absorb a large amount of heat in coal water slurry, thereby cold gas efficiency is reduced, oxygen consumption, coal consumption are increased; Coal-water fluid concentration has requirement to the paste-forming properties of coal, and the ash content in coal and ash fusibility are had to strict demand, and these requirements have caused the Application Range of coal to narrow, particularly for the too low faulty coal of calorific value, and coal water slurry charging poor effect; Gasification furnace fire brick is shorter service life, is generally 1～2 year; Gasifier nozzle is shorter service life.
Therefore water coal slurry pressure gasification and dry coal powder pressure gasifying respectively have superiority, and have half share.If but solved a coal dust high-pressure delivery difficult problem, coal dust liquid water content requires to relax, vapor pressure is further enhanced, dry coal powder pressure gasifying will have more advantage so, significantly reduce the energy consumption of synthetic briquette gasification, increasing the competitive power of Coal Chemical Industry, is also that Coal Gasification Technology is obtained one of hope that great-leap-forward breaks through and focus.
The spiral pump of carrying for powder pressing at present, have that working stability, sealing property are strong, easy and simple to handle, the advantage such as reduced investment, system are reliable, the granular materials such as cement, coal dust, petroleum coke powder, raw meal powder, breeze are widely used in, especially be not afraid of in the air-transport system of pressing materials, but due to the gap of helicallobe and delivery pipe, the highest operating pressure is not more than 0.6MPa.Therefore develop high pressure resistant, low energy consumption, powder conveying pump simple to operate, reliable, reduced investment is one of current coal gas fluidized bed gasification difficult problem urgently to be resolved hurrily.
Three, summary of the invention
Object of the present invention is exactly in order to overcome defect that existing powder conveying pump technology exists and not enough and a kind of powder high-pressure delivery pump is provided, there is the advantages such as high pressure resistant, simple in structure, reliable, energy consumption and investment be low, can meet type coal gasification technology is combined in branch of industry requirement to high-efficiency large.
