Abstract

The invention relates to a new method and a new technique for performing flue gas desulfurization and decarburization, which are widely suitable for recovering sulfur dioxide (SO2)-containing and carbon dioxide (CO2)-containing acidic gases, such as power plant flue gas (boiler flue gas), gas-making blowing gas recovering flue gas, coke-oven gas, oil refinery tail gas and the like. By the method and the technique, the SO2 and the CO2 are recycled completely; the environmental pollution problem of the SO2 and the CO2 is solved; and products produced by the method and the technique bring huge economic benefit. The technique fills the technical blank that the flue gas can be desulfurized, but cannot be decarburized, and huge economic benefit is not generated at home and abroad. In the method and the technique, a flue gas heat recovery part, a cooling and dedusting part, a gas pressing absorption part, a reaction kettle, a separator, a decomposer and a recovery system are provided. The method and the technique are characterized in that: the SO2 and the CO2 are removed at the same time; and high-purity magnesium carbonate (MgCO3), magnesium oxide (MgO) or sodium carbonate (NaCO3) and the like are produced. The environmental pollution problem of the SO2 and the CO2 is solved fundamentally.

Description

The new method of flue gas desulfurization, decarburization, new technology
Technical field:
The present invention extensively is adapted to power-plant flue gas (boiler smoke), producing gas blower reclaims flue gas, oven gas, refinery tail-gas etc. and contains SO 2, CO 2The gas of sour gas reclaim.The present technique technical maturity reclaims SO 2, CO 2Thoroughly, not only solved SO 2, CO 2Also can bring huge economic benefit to the pollution of environment and the product of production.Present technique has been filled up both at home and abroad the technological gap that can not decarburization also can not produce great economic benefit to flue gas desulfurization.
Background technology
Present stage flue gas desulfurization is to utilize the desulfurization at normal-pressure technology, can only remove the SO in the flue gas 2, to causing the CO of greenhouse effects 2Gas does not remove substantially, more can not produce new product, so can not produce economic benefit for enterprise, causes a large amount of CO 2Gas is discharged in the air, has promoted the generation of greenhouse effects, makes global warming, and pestilence is walked crosswise, and survives in living to people and has caused grave danger, has brought serious crisis for the survival and development of enterprise.
Summary of the invention
The present invention adopts series of process technology such as flue gas energy recovery, cooling and dedusting, gas pressurized absorption, reactor, separator, decomposer and recovery system that flue gas is handled, and absorbs the SO in the flue gas simultaneously 2, CO 2Gas generates the MgCO of new high product purity 3Or Na 2CO 3Deng, fundamentally solved SO 2, CO 2Pollution to environment.
Technology of the present invention is the drawback according to a present stage flue gas desulfurization not decarburization of desulfurization, thereby new method, the new technology that flue gas is handled invented in research.Its technology is: utilize superconductor technology that the heat energy in the flue gas is reclaimed heating air blast air, reduce boiler coal consumption, behind cooling and dedusting, gas pressurizeed removes SO 2, CO 2, generate new product MgCO by chemical reaction 3, MgO or Na 2CO 3Deng.
Owing to adopt foregoing invention technology, with present stage the flue gas desulfurization technique technology compare, have the following advantages:
1, removing SO 2In the time of gas, can also remove CO 2Gas is stopped flue gas environment is polluted.
2, produce new product, can bring abundant economic benefit, thoroughly solved the present stage flue gas desulfurization technique and only invested the drawback of not having repayment to enterprise.
3, owing to employing pressurizing absorption technology, the business equipment reduced investment, good absorbing effect is to the SO in the flue gas 2, CO 2Gas has carried out radical cure completely, has fundamentally solved this difficult problem of flue gas environmental pollution.
The specific embodiment:
Boiler smoke utilizes the superconduction heat transfer technology, and the air blast air is heated, and has reduced boiler coal consumption, and gas through after the cooling and dedusting pressurization, removes SO more simultaneously 2, CO 2Discharge behind the gas.Absorption liquid enters the reactor reaction, forms product.
