Abstract
The invention relates to a method for recycling the waste gas generated by burning hydrocarbon fuel and water/steam, which comprises that collecting the waste gas in the heater, reducing the temperature under 30Deg. C, pressurizing and feeding into heater, adding water/steam at 100-150Deg. C into the heater and feeding some hydrocarbon fuel to form the mixed fuel, collecting the waste gas generated by burning the mixed fuel, reducing the temperature via the heat exchanger, pressurizing and feeding into the heater, adding water/steam and fuel into the heater to form the mixed fuel, circulating aforementioned processes. The mixed fuel comprises 100m<3> waste gas, 20-25L water/steam, 0.3-0.88L hydrocarbon fuel, and the waste gas comprises 55-65% H2 and 25-32% CO2. The invention can use 1-3% feeding hydrocarbon fuel to reduce the energy consumption and pollution.
Description
Technical field
The waste gas that the present invention relates to a kind of hydrocarbon fuel and water or water vapour burning generation reclaims the method that the back recycle burning utilizes.Be applicable to that the waste gas circulation that gas engine, internal combustion engine, boiler, heating furnace etc. are made the heater of the energy with hydrocarbon fuel utilizes again.
Background technology
Before the present invention made, heaters such as traditional gas engine, internal combustion engine, boiler, heating furnace all were to make fuel with hydrocarbon fuel, produced great amount of heat through the burning of bubbling air in heater, also will produce a large amount of flue gases simultaneously.This method fuel consumption is many, and the flue gas of generation directly enters atmosphere, contaminated environment.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the method that the waste gas recovery back recycle burning that provides a kind of hydrocarbon fuel that can the waste gas recovery back recycle burning that combustion of hydrocarbon fuel produces be utilized and water or water vapour burning to produce utilizes.
The objective of the invention is to realize like this: the waste gas that a kind of hydrocarbon fuel and water or water vapour burning produce reclaims the method that the back recycle burning utilizes; Behind its gas sampling, be cooled to below 30 ℃ through heat exchanger, and then pressurization feeds heater hydrocarbon fuel in the heater and water or water vapour burning generation; The water or the water vapour that in heater, feed 100 ℃-150 ℃ simultaneously again constitute fuel combination with additional a spot of hydrocarbon fuel; After the waste gas that produces behind the mixed fuel firing regathers, through the heat exchanger cooling, feed heater more again; In the pressurized, heated device, feed water or water vapour and postcombustion again and constitute fuel combination; So recycle of---, is reclaimed the purpose that the back recycle burning utilizes with the waste gas that reaches hydrocarbon fuel and water or water vapour burning generation.In the said fuel combination, the proportioning of each component is: waste gas 100m
3, water or water vapour 20L-25L replenish hydrocarbon fuel 0.3L-0.88L, H in the waste gas
2Account for 55%-65%, CO
2Account for 25%-32%.
The present invention adopts a spot of additional hydrocarbon fuel, with the H in the waste gas
2Constitute fuel combination with water or the water vapour of atomizing, renewable, to invest for a short time, energy consumption is low, can eliminate environmental pollution.After tested, the present invention can be than the energy-conservation 95%-98% of traditional method, and useless flue gas discharges 90-95% less, can reduce energy resource consumption and environmental pollution widely.
The specific embodiment
The waste gas that the present invention relates to a kind of hydrocarbon fuel and water or water vapour burning generation reclaims the method that the back recycle burning utilizes, and behind its gas sampling with hydrocarbon fuel in the heater and water or water vapour burning generation, is cooled to below 30 ℃ through heat exchanger; And then pressurization (≤6mpa) feed heater; The water or the water vapour that in heater, feed 100 ℃-150 ℃ simultaneously again constitute fuel combination with additional a spot of hydrocarbon fuel, after the waste gas that produces behind the mixed fuel firing regathers, again through the heat exchanger cooling; Pressurization feeds heater again; In heater, feed water or water vapour and postcombustion again and constitute fuel combination,---, so recycle; In the said fuel combination, the proportioning of each component is: waste gas 100m
3, water or water vapour 20L-25L replenish hydrocarbon fuel 0.3L-0.88L, H in the waste gas
2Account for 55%-65%, CO
2Account for 25%-32%.
