Description
Technical field
The present invention relates to a kind of novel CO
2Seizure device relates in particular to the liquid oxygen that is complementary with oxygen-enriched combusting zero-emission internal-combustion engine system and solidifies CO
2Device.
Background technique
Require strict day by day today in energy-conservation and environmental protection etc., the energy-conservation and environmental protection research of motor becomes the focus of current research.Oxygen-enriched combusting is one of main mode of energy saving, and oxygen-enriched combusting can make fuel combustion more abundant, eliminates the generation of pollutants such as CH, CO, obtains higher pressure peak, thereby the acting ability of motor is improved.But contain nitrogen in the common air, the coal hydrogen fuel can produce CO
2And NO
xTherefore the problem of pollutant starts with from engine combustion-supporting gas, and the research internal-combustion engine solidifies CO with liquid oxygen
2And having suitable realistic meaning with the combustion-supporting new method of liquid oxygen, the realization of this method can thoroughly solve engine producing CO
2And NO
xThe problem of pollutant.Utility model patent (ZL201020576059.2) has provided a kind of overall plan of the solid carbon zero-emission internal-combustion engine of liquid oxygen, but not to CO
2Seizure device study; Application for a patent for invention (CN201010171423.1) has designed the solid carbon device of a kind of ammonia process, with the CO of chemical raw material recovery boiler generation
2, but can not be to the CO of engine exhaust
2Catch.The present invention is for the CO that catches in the exhaust gases of internal combustion engines
2Device has carried out system research.
Summary of the invention
In order to realize catching CO
2, need utilize vaporization of liquid oxygen to absorb heat and make CO
2Become dry ice, the device of the present invention's design both can satisfy the vaporization of liquid oxygen oxygen-enriched combusting, can also utilize vaporization of liquid oxygen to absorb heat simultaneously and catch the CO of engine emission
2, make motor realize zero-emission.
The present invention makes the tail gas CO that produces behind the liquid oxygen oxygen enrichment combustion in IC engine
2Be reduced near 50 ℃ through condensed water, pass through this device then,, liquid oxygen is heated is vaporized into oxygen, a part of CO with the liquid oxygen convection heat exchange
2Be condensed into dry ice, it is combustion-supporting that the oxygen mix after a part and the vaporization gets into internal-combustion engine, realizes oxygen-enriched combusting.
Adopt the present invention can make internal-combustion engine realize catching CO
2The time eliminated NO again
xGeneration, be oxygen with vaporization of liquid oxygen, with the CO that does not sublimate
2The common internal-combustion engine that gets into carries out oxygen-enriched combusting, has eliminated the generation of CH and CO.Both improve the efficiency of internal combustion engine, realized the zero-emission of internal-combustion engine again.Internal-combustion engine and this device are used; Can make internal combustion engine in narrow space; Simultaneously need can be applied to the occasion of zero-emission, such as military tunnel construction vehicle, tunnel excavator, drilling well generator, submarine generator, occasions such as ordnance missile emission vehicle.
Description of drawings
Fig. 1 is CO
2Seizure device figure.
Among the figure: 1-inlet, 2-condensate pipe, the 3-first layer sieve of sublimating, first dry ice trap of 4-, the 5-second layer sieve of sublimating, second dry ice trap of 6-, the 7-air outlet, the 8-liquid oxygen enters the mouth, 9-liquid oxygen baffle.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
Concrete technological scheme of the present invention is: like Fig. 1, and CO
2Seizure device has shell, and inlet 1 is arranged on the shell side bottom, and air outlet 7 is arranged on shell upper, and sublimate sieve 3 and the second layer of first layer sublimates that 7 direction is set in turn in said enclosure to sieve 5 to the air outlet along inlet 1.
Progressive below narration CO
2The principle of seizure device.(overwhelming majority is CO to the tail gas that produces behind the combustion-supporting internal-combustion engine oxygen-enriched combusting of liquid oxygen
2) through condensate pipe 2 condensations of outlet pipe tail end, temperature is reduced near 50 ℃, through 1 this seizure device of entering that enters the mouth.Simultaneously liquid oxygen gets into through the liquid oxygen inlet 8 at device top, arrives liquid oxygen baffle 9, and liquid oxygen flows to first layer the sublimate surface of sieve 5 of sieve 3 and the second layer of sublimating respectively along baffle 9, forms liquid film attached on the sieve aperture.At this moment, through CO
2The CO that inlet 1 gets into
2The arrival first layer is sublimated and is sieved 3, and with the liquid oxygen convection heat exchange that adheres to above that, liquid oxygen is heated and is vaporizated into oxygen, CO
2Sublimating is dry ice particles, because action of gravity, dry ice falls and arrives sublimate first dry ice trap 4 of sieve 3 bottoms of first layer.Do not sublimate and be the CO of dry ice
2Gas arrives the sublimate surface of sieve 5 of the second layers through the first layer sieve 3 of sublimating, and proceeds convection heat exchange with the liquid oxygen that adheres on it, this moment vaporization of liquid oxygen, CO
2The particle arrival second layer after gas is sublimated is sublimated and is sieved second dry ice trap 6 of 5 bottoms.Oxygen behind the vaporization of liquid oxygen and the CO that does not also sublimate
2Gas is mixed into new gas, through the air outlet 7 of this device, discharges this device, gets into induction system of internal combustion engine.The second layer of this device design sieve 5 of sublimating is finer and closely woven than the first layer sieve 3 of sublimating, and sieve plate makes most of CO because first layer is sublimated
2Gas is all sublimated into dry ice, and remaining have only a small amount of CO
2Gas is not sublimated, in order to make CO still less
2Gas is not sublimated and 7 discharges along the air outlet, needs finer and closely woven sieve aperture.In order to prevent and heat exchange with outside, adopt the insulation heat insulation layer that device is carried out thermal insulation.
The internal-combustion engine of using system of the present invention can be operated in need zero-emission, in the narrow space; Such as military tunnel construction vehicle, tunnel excavator, drilling well generator, submarine generator; Occasions such as ordnance missile emission vehicle simultaneously; The dry ice that reclaims can carry out recycle, is used for refrigeration, senior Dry ice cleaning agent, plant nutrient ingredient etc.
The invention is not restricted to above description to embodiment; The content that those skilled in the art disclose according to the present invention; On basis of the present invention, needn't pass through improvement and the modification that creative work carries out; Selection such as suction tude supercharging device and dry ice mothballed plant is provided with etc., all should be within protection scope of the present invention.
