Description
What the present invention relates to is a kind ofly to do raw material with Wingdale, and coal is made the shaft furnace formula carbonic acid gas producer of fuel.
At present, the production method of the carbon dioxide in the kiln gas that the extraction mechanize shaft furnace production lime that the production of carbonic acid gas is both at home and abroad adopted produces, the carbon dioxide content in the kiln gas is at 35-42%, and content is lower.Because shaft furnace up-down structure basically identical, the coal charge multifuel combustion ventilates up and down, thereby impurity and harmful substance contents are very high in the carbon dioxide gas that produces.The mechanize shaft furnace is given the very bad control of wind in operation, give wind many in the kiln gas carbonic acid gas ratio reduce, temperature is too high, causes the big or dross of purification amount.In kiln gas, extract carbonic acid gas, need huge equipment for purifying, a large amount of alkali, various medicaments, hot gas etc., cost is quite high.The carbon dioxide gas purity of Ti Quing is not high in this way, and quality is difficult to guarantee.A kind of high-pureness carbon dioxide producer---electrothermic type carbon-dioxide generator.Be to do flue by silicon carbide, nichrome wire is equipped with in the flue outside, energising heats up, when being warmed up to 350-400 ℃, ore shuts fire door, after opening purging valve and bleeding off the not high carbon dioxide of purity, shut purging valve, producer begins works better, the carbon dioxide gas of producing with this stove adsorbs purification through cleaner, and purity can reach 99.5-99.9%.But, can not do raw material with Wingdale because this producer maximum operating temperature can only reach 950 ℃, thereby can only use the higher low-temperature decomposition raw material of cost.Current consumption is big, and output is little, under the relatively nervous situation of China's electric power, is unsuitable for big industrial production, and economic benefit is also undesirable.
Purpose of the present invention is exactly to design a kind of novel carbonic acid gas producer, this stove had both absorbed the mechanize shaft furnace and had done raw material with Wingdale, coal is done the big industrial characteristics of fuel, having absorbed the electrothermic type carbon-dioxide generator again heats outside flue, the ore of heating source and heating separately, can obtain the characteristics of high-pureness carbon dioxide, traditional firing mode is come a thoroughly change.
Carbonic acid gas producer of the present invention be by be positioned at body of heater top and bottom into and out of batch can, the preheating section on top, the calcining section at middle part, the vexed grey chamber and the cooling room of bottom, the combustion chamber of body of heater outside and the monitoring CO
2Concentration, the electrical control system of control furnace temperature is formed.
The preheating section that is positioned at upper of furnace body has a preheating flue that is positioned at waste heat burner hearth center of being made by 3Cr13Ni7Si2 high temperature steel, the preheating flue can worked below 700 ℃, for heat conductivility that improves the preheating flue and the erosion resistance that improves steel plate, scribble the high-temperature infrared wire material in the both sides of preheating flue, the effect of preheating flue is the Wingdale ore that is used in the waste heat heating input stove of calcining section.Because entering the waste heat of preheating section, the calcining section can reach 600 ℃-800 ℃, only do not absorb by the ore that enters the preheating flue, thereby be equipped with the jet flow water cooler in the outside of waste heat burner hearth, this jet flow water cooler is a cylinder that is equipped with numerous aperture on barrel, be divided into three sections outsides that are trapped among the waste heat burner hearth, when freezing air when the blast inlet of preheating section bottom enters water cooler, utilize the high flow rate of freezing air that heat is taken away, the warm air that heats is by to enter the combustion chamber combustion-supporting with the anastomosing hot-blast outlet in combustion chamber.The skin of jet flow water cooler is to accompany perlitic thermal insulation layer in the middle of the two-layered steel plates.
Be positioned at calcining Duan Youyi the calcining flue of being made by 1Cr25Ni20Si2 high temperature steel at body of heater middle part, the calcining flue places the center of high-temperature burner hearth, and is connected with the preheating flue.In order to improve radiation capacity and the corrosion resistance and the tear resistance of calcining flue, both side surface at the calcining flue scribbles the high-temperature infrared wire material, when the ore that is heated to 700 ℃ in the preheating flue enters the calcining flue, high heat by high-temperature burner hearth is Wingdale reheat to 800 ℃-1100 ℃, and at this moment ore begins to resolve into CaCO
3And CO
2Temperature in the high-temperature burner hearth is mounted on the thermopair and the outer electric heating control table of body of heater of this section and controls, the air door umformer of electrothermal meter and gas blower links together and controls the size of air output, makes the temperature in the high-temperature burner hearth be controlled at the optimum temps that ore decomposes all the time.The thermal insulation layer of forming with lagging material that is built into by refractory brick at the skin of high-temperature burner hearth.
Bottom in the calcining section, the top of cooling room is a vexed grey chamber, 800 ℃ material under the calcining section keeps temperature to continue to decompose at this, when material is reduced to indissoluble temperature, enter water cooler, water cooler is made up of many cooling tubes, and being inserted in needs in the middle of the refrigerative lime, by the high pressure cold wind that enters in the pipe heat is taken away, heated freezing air enters combustion chamber hot blast passage and carries out secondary to mend wind combustion-supporting by being contained in outlet this chamber and that communicate with combustion chamber hot blast passage.
The combustion chamber is positioned at the body of heater outside, on the workplatform of calcining section lower end, communicated with a calcining section high-temperature burner hearth by hot-air channel, the combustion chamber is provided with from the heating duct of preheating section with from the secondary secondary air channel of cooling section, coal is sent into calcining section burner hearth after the combustion chamber is combustion-supporting by hot blast.Build by laying bricks or stones with ordinary red brick this outside, combustion chamber, and liner is built into refractory brick, is provided with two thermopairs in the combustion chamber, and the temperature and the hot-air channel mouth temperature of monitoring combustion chamber are with the temperature of control calcining section high-temperature burner hearth.
Be provided with a charging stock tank at the top of body of heater, a feeding gate is arranged at the top of jar, a bell is arranged at the bottom, when material loading in stove, the bell of closing the batch can bottom earlier guarantees the absolute sealing of flue, after material is filled it up with, feeding gate is closed, the air of outside can not be sneaked into, open bell, ore flows in the flue.
Be positioned at the discharge tank of furnace bottom, also be provided with two doors, the discharge door of the feeding gate on batch can top and batch can bottom at the two ends up and down of jar.When wanting discharging, close discharge door earlier, open feeding gate, allow the lime stream batch can that overfills, close feeding gate then, open discharge door.
CO
2Enter next process by the air outlet that is placed on cooling room.
This carbonic acid gas producer is provided with an electric control system, comprises an electric control platform, an electric heating control table and a CO
2Monitor.Can measure controlled temperature, coal consumption, ore amount, kiln gas free air delivery, drop temperature, carbonic acid gas free air delivery at any time, to air quantity etc.
Carbonic acid gas producer of the present invention, carbon dioxide content adds purification up to 95-99% with anti-method of purification in the furnace gas, carbon dioxide purity can reach 99.5-99.99%, the easily control of heating can make to form the big area high temperature section in the burner hearth and do not make the raw material burning, dross.Its main products Wingdale and magnesium oxide purity height, output height, full scale production are realized control automatically.
