Abstract
The carbon dioxide sex change device that coal furnace burns without discharge cycle, it is a kind of smokeless for coal furnace, by fume collection process, after carbon dioxide sex change in flue gas is become carbon monoxide, it is energy-conservation that the circulation of feeding burner hearth is burnt again, reduce discharging, environmental protecting device, in the process of usual coal furnace burning, a large amount of stack gas emissions can be produced, mainly contain in this stack gas emissions, carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxide, the materials such as nitrogen, first these stack gas emissions are collected, pass through desulfurization, denitration, after getting nitrogen, the mist of carbon monoxide and carbon dioxide, be pressed into carbon dioxide sex change device together---in charcoal bed reactor, carry out carbon dioxide at a warm condition in the reduction reaction of coal plastid: CO
2+ C=2CO, by reduction reaction, makes carbon dioxide reduction sex change be carbon monoxide, by these CO gas, sends into burner hearth circulation and burns.
Description
Technical field
The present invention is a kind of smokeless for coal furnace, by fume collection process, after carbon dioxide sex change in flue gas is become carbon monoxide, send into that burner hearth circulation burns again energy-conservation, reduce discharging, environmental protection, carbon dioxide sex change device that coal furnace burns without discharge cycle.
Background technology
Current China economy be in steadily, developing period fast, the development of the field such as industry, agricultural, national defence, science and technology is swift and violent.But under the large good prerequisite of this fast development, also there is a large amount of environmental protection problems and using energy source problem.How to realize the protection of environment and the Appropriate application of the energy, carry out energy-conservation, reduce discharging, the national policy of environmental protection is the vital task of pendulum in face of us.A large amount of consumption that since consistent, the economic development of China mainly relies on the energy have come, and wherein with regard to coal-burning boiler, various Industrial Boiler, life heating boiler, everywhere all, a large amount of consumes the coal resources of China to thermal power generation boiler etc.Numerous coal furnaces makes a large amount of emissions pollute air ambient, and haze is walked crosswise, and brings certain impact and harm to the development of country and the life of the people.
Summary of the invention
In order to solve the problem, the application provides a kind of, the carbon dioxide sex change device that coal furnace burns without discharge cycle.In the process of usual coal furnace oxidizing fire, be bound to produce a large amount of stack gas emissions, mainly contain in this stack gas emissions, carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxide, the materials such as nitrogen, stack gas emissions when coal oxidation first burns by we, by exhaust opening, place collects, and then introduces in desulfurization treating apparatus with pipeline and carries out desulfurization, introduce to get in nitre treating apparatus again and carry out getting nitre, take out nitrogen more afterwards.At this moment stack gas emissions by desulfurization, get nitre, get nitrogen after, just substantially only remaining carbon monoxide, and carbon dioxide, we are pressed into crucial carbon dioxide sex change device together these two kinds of mists---in charcoal bed reactor, carry out carbon dioxide at a warm condition in the reduction reaction of coal plastid, carbon dioxide in coal plastid by after reduction reaction, make carbon dioxide reduction sex change be carbon monoxide and:
cO 2 + C=2COreaction.Due to the highest price state that carbon dioxide has been carbon, non-oxidation possibility, so can only be reduced to 0 or lower valency, 0 valence state is then carbon simple substance, needs to introduce reducing agent coal.Carbon dioxide sex change device---charcoal bed reactor, it is the appearance body that there is multi-layer stacking reducing agent coal medium a kind of inside, carbon dioxide is passed into this charcoal bed reactor to be held in body, and the coal of inner multi-layer stacking reducing agent carries out reduction reaction, generates carbon monoxide:
cO 2 + C=2CO,this mist together with the part CO gas of originally just press-in, after necessarily than the air arranged and steam mixing, is sent into burner hearth, is constantly carried out the process of circulating combustion as generation fuel by this CO gas by the lump.So just the flue gas discharged in coal furnace combustion process, what all turn waste into wealth is utilized, and solves the problem of environmental pollution of toxic emission, in turn saves the consumption of coal resources.

Detailed description of the invention
Fig. 1
,in be the carbon dioxide sex change device that coal furnace burns without discharge cycle, each link flow process, first in coal furnace hopper (1), coal is added, coal is allowed to burn in the burner hearth (2) of coal furnace, at this moment coal burning can produce a large amount of stack gas emissions discharges, collect to enter in desulfurization treating apparatus (3) through pipeline (13) and carry out desulfurization, enter to get in nitre treating apparatus (4) through pipeline (13) more afterwards and carry out getting nitre, enter to get in nitrogen device (5) through pipeline (13) again after getting nitre and take out nitrogen.At this moment stack gas emissions by desulfurization, get nitre, get nitrogen after, just substantially only remaining carbon monoxide, and carbon dioxide, we are pressed into crucial carbon dioxide sex change device through pipeline (13) together these two kinds of mists---in charcoal bed reactor (6), carry out carbon dioxide at a warm condition in the reduction reaction of coal plastid, carbon dioxide in coal plastid by after reduction reaction, make carbon dioxide reduction sex change be carbon monoxide and:
cO 2 + C=2COreaction.By this CO gas and, the part CO gas of original just press-in together, after supercharging device (7) supercharging of pipeline (13), through air mixing place (8), after necessarily mixing than the air mixing of row and the steam of steam mixing place (9), this mist is sent in the lump in burner hearth (2), constantly carry out the process of circulating combustion as generation fuel.Fig. 2, middle carbon dioxide sex change device---charcoal bed reactor (6), it is a kind of appearance body, there is gas feed (10) one end holding body, the other end holding body has gas vent (11), there is the appearance storehouse (12) of multi-layer stacking reducing agent coal medium inside, and carbon dioxide, from import (10), is passed into this charcoal bed reactor and holds in the appearance storehouse (12) of body (6), carry out reduction reaction with the coal of inner multi-layer stacking reducing agent, sex change generates carbon monoxide:
cO 2 + C=2COdischarge from outlet (11), enter the local process of pipeline (13).
