Description
Technical field
The utility model design coal gasification apparatus field is specially a kind of coal water slurry water wall vapourizing furnace.
Background technology
The resource situation of China energy has determined us to be unable to do without coal, but in the coal utilization process, because method is improper or technology is not advanced, has produced the serious environmental pollution.Along with fast development of national economy, more and more higher to improving energy transformation efficiency and requirement on environmental protection, press for and develop clean coal technology, coal resources are carried out rationally and effectively utilization, improve whole energy transformation efficiency, reduce pollution to environment.Developing large-scale, high effect cleaning Coal Gasification Technology is to solve the task of top priority that China energy is rationalized problem.Adopt advanced gasification technology to greatly develop Coal Chemical Industry and related industries, both can reduce the pollution to environment, also can enlarge the coal scope, raw material can be used the bituminous coal for replacing anthracite, has good social benefit and economic benefit, is the important method of dealing with problems.The cleaning of coal and efficient utilization are the great technical tasks in current China energy and environment protection field, also are one of gordian techniquies of Chinese national economy sustainable development.
Coal Gasification Technology is the main path that primary energy source is converted into clean secondary energy, and its product is fuel gas (coal gas), synthetic gas, reducing gas, hydrogen, carbon monoxide.The coal gasification technology has obtained using widely in the production of combined cycle (IGCC) power generation assembly, synthetic ammonia and synthesizing methanol industry, producing acetic acid by carbonylation method and acid anhydrides industry, sponge iron, the fields such as preparation of pure carbon monoxide, and effective utilization of the various energy that produces of how will gasifying is the key that reduces device running cost.At present, in the technology that adopts air flow bed to gasify, representationally mainly contain two kinds: adopting coal water slurry is that the vapourizing furnace of raw material has Texaco (Texaco), and its deslagging mode is liquid wet method deslagging; The employing dried coal powder is that the vapourizing furnace of raw material has shell (Shell), and its deslagging mode is a slag tap, and the deslagging mode of these two kinds of air flow bed is all fool proof, stable, but all has defective.These two kinds of technology are all grasped abroad in major company's hand, if adopt these technology just must the expensive patent royalty of payment; Texaco (Texaco) device coal-water slurry nozzle is in the vapourizing furnace high-temperature zone and is subjected to the abrasion of coal grain, be generally work-ing life about 40 days, lining of fire brick is adopted in the combustion chamber, if chamber temperature is too high, firebrick loss is very fast, so can only the low coal of ash fusion point; Shell (Shell) investment is very big, and it adopts the dry powder charging, measures inaccurate, combustion chamber furnace temperature fluctuation is big, has caused threat for the water wall life-span, and its high-temperature synthesis gas adopts complicated energy recycle device, requirement to equipment is very high, and the long-term operation rate is low, and year working rate is also low.The present situation of my company is at present: the existing coal gasification apparatus that uses, the system gas of employing static bed gas making.The problem that exists is, raw material uses local anthracite block coal and coke, and its efficient is low, it is big to pollute, and the transportation difficulty, the price height.But not slag-slag two-stage gasifier must burn trucking costs high Shenmu County coal or Huating coal.
Summary of the invention
The utility model provides a kind of coal water slurry water wall vapourizing furnace for the easy loss of body of heater that solves existing various vapourizing furnaces and exist, the inferior problem of inefficiency.
The utility model is realized by following technical scheme; a kind of coal water slurry water wall vapourizing furnace; comprise that top has import; the bottom has the housing of outlet; in housing, be provided with the combustion chamber and the shock chamber that have water wall; top, combustion chamber is the burner mouth; the bottom, combustion chamber connects the shock chamber; the porose dividing plate of perisporium arranged outside at combustion chamber and shock chamber's connecting portion; be provided with the import of protection gas on housing top, be provided with the secondary oxygen feeder on the combustion chamber, the position of position, the shock chamber correspondence on housing is provided with syngas outlet; the side of lower housing portion is provided with the ink outlet, lock hopper recirculated water inlet.
Coal water slurry water wall vapourizing furnace under the utility model can adopt the coal water slurry charging to get mode, measures the problem of being forbidden to cause furnace temperature fluctuation thereby solved charging; Water wall is adopted in the combustion chamber, removes expensive refractory brick, can burn the coal of high ash melting point, and the shock chamber adopts water wall and water-bath cooling, has simplified the complicated energy recycle device of shell (Shell).
Compare with existing apparatus: it adopts lining of fire brick non-slag-slag two-stage gasifier, can not burn high-ash-fusion coal, and the water wall structure that the utility model has used shell (Shell) to be adopted, coal water slurry water wall vapourizing furnace coal is applied widely, can burn high-ash-fusion coal, and energy consumption is lower, can effectively reduce production costs, and has effectively saved the energy; Used its classification oxygen supply of non-slag-slag two-stage gasifier, solved Texaco (Texaco) device burner shortage in work-ing life point, adopt its coal water slurry charging of non-slag-slag two-stage gasifier, solved the inaccurate problem of shell (Shell) charging metering; Coal water slurry water wall vapourizing furnace combustion volume increases, and prolongs carbon in the combustion chamber residence time, has improved the transformation efficiency of carbon, can make that carbon content reduces greatly in the slag; Adopted non-slag-its chilling process of slag two-stage gasifier; Make it into water wall recovered energy, can the by-product middle pressure steam, can avoid high-temperature synthesis gas directly to cool off, the problem that energy wastage is bigger is for system has saved a large amount of energy.Comprehensive, device described in the utility model can burn local high-ash-fusion coal, realizes the feed coal localization, has energy-efficient, environmental protection, the big advantage of single stove gas forming amount, is the novel vapourizing furnace of large industrialized.
