Description
Technical field
The invention belongs to a kind of coke gasification and produce the method and apparatus of coal gas.
Background technology
Crushed coal pressurized-gasification furnace is a kind of fixed bed coal gasifier, owing to requiring low to feed coal, i.e. except heavy caking coal
Outward, remaining coal can gasify, particularly low-order coal and the colm of high ash melting point and Jiao of gasifying.This gasification furnace is by extensively
Be applied to coal synthesis ammonia, methanol, dimethyl ether, synthesis oil and gas natural gas field.But the broken coal of industry park plan at present
The crushed coal pressure gasifying technology used in pressure gasification process is suitable for gasifying and has the coal of dry distilling, drying layer, dry in gasification
Absorbing heat when dry, dry distilling, top of gasification furnace temperature is unlikely to exceed more than gasification furnace material bearing temperature, and coke is anti-in addition
Answer poor activity, as such as the entrained flow bed gasification technologies such as Shell, GSP, space flight stove, water-coal-slurry and fluidized gasification technology are difficult to completely
Reaction (efficiency of carbon con version is low), is not suitable for coke gasification, and in the face of the most lonely coke industry, exploitation coke gasification technology is to compel
The problem of the eyebrows and eyelashes.
At present crushed coal pressure gasifying technique use in dedusting, removing oil operation for Modern Coal-based Chemical technical manual second
Version, fixed bed gasification technological process in 5 introduced in page 424 to 428, all use water washing dedust, removing oil work technique, cause thick
The display loss amount of coal gas, is unfavorable for heat recovery and utilization, also makes that gas liquor circulating load is big, operating cost is high.Patent: coal system
The technique of clean gas and device, the patent No.: the cyclone dust removal of patent use, removing oil disclosed in 201410767710.7, but
Cyclone dust removal structure is undisclosed, raw gas outlet temperature easily occurs tar condensing time low, cause slag-drip opening blocking, be difficult to stable fortune
OK.Patent: Dual tangential circulating flow type cyclone dust remover, the patent No.: make in cyclonic separation disclosed in 01243740.9 and above-mentioned patent
Cyclone dust removal, removing oil there is the same problem.Along with China's rapid industrial development, chemical plant installations is progressively towards high temperature, height
Pressure, the development of large-scale, particularly Coal Gasification Technology require vapor pressure at least more than 40 kilograms, day coal feeding amount reach thousand
Tonne, the fat coal organic C storage adding gasification is fewer and feweri, and colm ratio is stepped up on the contrary, and particularly ash fusion point is more than
The ratio of the coal of more than 1500 degree is stepped up so that gasification gas or the temperature of follow-up waste gas, pressure the most correspondingly improve,
Patent name: a kind of High Temperature High Pressure waste heat boiler, application number: the patent of 201110462710.2 solves high pressure, high temperature problem, but
The heat recovering process that uses of our current fixed bed gasification and equipment: the Modern Coal-based Chemical technical manual second edition, the 424th to
It is all one-level recuperation of heat that page 428 introduce typical fixed bed gasification technological process in 5, produces the steam of a kind of grade, coke gas
Change coal gas thick mouth temperature high, use former flow process not only to cause the wasting of resources, the most also pollute environment.Patent name: pressing gas
With waste heat boiler, application number: the patent of 200510010273.5 is mainly used in solving coal gasification, improves heat recovery efficiency,
But remain one-level recuperation of heat, produce the steam of single-grade, fail fully Waste Heat Recovery to be utilized.
Summary of the invention
The purpose of the present invention is contemplated to overcome the shortcoming and defect in above-mentioned technology, it is provided that a kind of without washing coal gas Aquatic product
Raw, recycling gradable to coal gas waste thermal energy, the coke gasification of the different brackets steam simultaneously produced produces the method for coal gas
And equipment.
The method of the present invention, comprises the steps:
(1) with coke as raw material, through crushed coal pressure gasifying generate pressure be 1.0-8.0MPa, temperature be 500-650 DEG C
Oil-containing dirt raw gas；
(2) cyclone separator that oil-containing dirt raw gas enters in dedusting cyclone separator is separated, oil in coal gas
Dirt is affected with unexpected reduction of speed dual function when leaving inner barrel by centrifugal force, makes oil dirt and portion gas from inner barrel and urceolus
The gap of body returns conic tube and carries out spin separation, and the gas after separation mixes with the oil-containing dirt raw gas entering cyclone separator
And again separate, obtain in every cubic metre of raw gas the content of oil dirt at the raw gas of 1-80mg and oil-containing dirt；
