Working process of the present invention is as follows:
Complete assembly is made up of Coking and Gas stove main furnace body and heat exchange, separator two parts.Can adapt to most of coals; Also can adapt to gas (charcoal) and change biomass, as wood, bamboo, cotton stalk, rice husk etc., full-automatic intelligent environmental friendly clean fuel gas system gas and multi-joint-production apparatus such as rubbish rod.Can in a covering device, produce charcoal, system gas, reclaim by-product in the gas purification process, the generating of waste heat system steam steam supply turbine.Realize Poly-generation and recycle.
When coal coking and system gas:
Coal enters the storage bin of this device at first by automatical feeding system, and the storage bin capacity of this device is enough big, upward expires material and can move more than 6 hours at least.Requirement to feeding system has just reduced like this.Behind the material loading,, control in real time advancing inventory by having the inlet amount controller of delicate metering device.The foundation of control is mainly from the thing position detecting sensor that is contained in this bottom of device.When sensor detecting to signal, behind the central processing unit analytical data, affirmation is fed in raw material after need adding inventory.In material enters stove, at first enter into the destructive distillation layer, because destructive distillation layer temperature be not too high, coal is separated out volatilization during this period and is graded behind the material, enters zone of oxidation again.Under the high temperature of zone of oxidation, material is cleaved, generates CO
2, and then be reduced into CO on zone of oxidation top, mix with the hydrocarbons of golf calorific value in the low temperature volatile matter of separating out in the destructive distillation layer again, produced generator gas.
In this process, because vaporized chemical is not normal temperature air but is replaced by the high temperature air more than 350 ℃ that the interchanger recovery waste heat produces, this has just accelerated gasification rate, materials such as its phenol that has enough surpluses allow once to generate in the gasification, naphthalene, the tar zone of oxidation of flowing through is once more handled, make that the combustion gas that generates is cleaner, can reach the requirement of delivering to the oil engine generating.If be used for burning boiler, boiler tail is not adorned desulfurization and dedusting also can reach the geographic emission request of two classes.
The combustion gas of Chan Shenging in this way, the every mark side of dustiness is less than 50 milligrams, and the every mark side of tar content is less than 10 milligrams, and the every mark side of sulfide hydrogen all is better than present national standard less than 40 milligrams.
This device of the present invention, the gasification rate of coal in stove is controlled.After coal enters furnace chamber, the time along with gasification, slowly move down, crossfade into coke.Coke has arrived the coke layer of bottom, because perfect measuring instrument is arranged, can directly not discharged out of the furnace.Have only to be checked measure the requirement that has reached coke really after, just can lead to and discharge out of the furnace.At this moment the coke that discharges out of the furnace, carbon content all reach design requirements.
Because above-mentioned accurate temperature control has been arranged, can prevent effectively that the coal grain from tie quarrel in gasification, so just relaxed restriction widely to coal.Except that few several coals, almost can select for use any coal to carry out coking and gasifying electricity generation.
During gasified bio-matter:
Material enters the storage bin 1 of this device at first by automatical feeding system, and the storage bin capacity of this device is enough big, upward expires material and can move more than 3 hours at least.Requirement to feeding system has just reduced like this.Behind the material loading,, control in real time advancing inventory by having the inlet amount controller of delicate metering device.The foundation of control is mainly from the thing position detecting sensor that is contained in this bottom of device.When sensor detecting to signal, behind the central processing unit analytical data, affirmation is fed in raw material after need adding the amount of material.In material enters stove, at first enter into the destructive distillation layer, because destructive distillation layer temperature be not too high, separate out volatilization during this period and grading behind the material, enter zone of oxidation again.Under the high temperature of zone of oxidation, material is cleaved, generates CO
2, and then be reduced into CO on zone of oxidation top, mixing, produced the combustion gas of biomass generation stove with the hydrocarbons of golf calorific value in the low temperature volatile matter of separating out in the destructive distillation layer.In this process, material directly comes out to become the destructive distillation charcoal to coking chamber.
In this process, because vaporized chemical is not normal temperature air but is replaced by the high temperature air more than 350 ℃ that the interchanger recovery waste heat produces, this has just accelerated gasification rate, and materials such as its phenol that has enough surpluses allow once to generate in the gasification, naphthalene, tar are handled once more.Make that the combustion gas that generates is cleaner, can reach the requirement of directly delivering to fuel engine power generation.
The fuel gas temperature of coming out of the stove is very high, must cooling.The present invention adopts the mode of stepped control temperature, is implemented in the process of cooling strictness and controls temperature well, adopts the mode of condensation rapidly that phlegma is sorted out recovery categorizedly.Vinegar liquid after the recovery and tar be can not go here and there assorted.
The biological fuel gas of Chan Shenging in this way, the every mark side of dustiness is less than 30 milligrams, and the every mark side of tar content is less than 10 milligrams, and the every mark side of sulfide hydrogen has reached present national standard fully less than 40 milligrams.Deliver to occupy domestic gas and generate electricity and to meet the demands fully.
This apparatus features is not only energy-conservation but also environmental protection, is the direction that meets energy-saving and emission-reduction that current country advocates.And owing to adopted comprehensive utilization, economic benefit will have several times to improve.
This device is special environmental protection in gas-making process; Except that generator tail gas and noise, almost zero release zero is polluted.When gas (charcoal) is changed biomass, can in a covering device, produce charcoal, system gas, reclaim by-product in the gas purification process, the generating of waste heat system steam steam supply turbine.Realize Poly-generation and recycle.
This device is furnished with perfect gas ingredients and analyzes on-line monitoring means and intelligence control system, can analyze fast thousands of times than artificial laboratory, and be successive.These data are made accurate judgement by computer, in time adjust operating mode, make efficiency higher, reduce discharging better.
When the recovery combustion gas was generated electricity, the total system of this device did not need gas-holder, has economized cost and has economized the place that takies yet.Because the function of these characteristics has been arranged, the response speed of total system is exceedingly fast, when adjusting, load can get caught up in the variation of load fully, and make total system pressure highly stable.
The total system of this device only needs the technician on duty, need not the operator.
