Description
Technical field
This utility model relates to Thermal Power Engineering Field, particularly a kind of pressure-variable adsorption oxygen-enriched burning device.
Background technology
Oxygen-enriched combusting is that the gaseous mixture utilizing air to separate the pure oxygen obtained and a part of boiler exhaust composition replaces air
Oxidant when doing fossil-fuel-fired, this combustion system can make flue gas CO2 at concentrations up to more than 85%, can divide
From and by most flue gas direct liquefaction recycle, the recovery of beneficially CO2, can effectively reduce the row of greenhouse gases
Putting, oxygen-enriched combusting can also effectively reduce the discharge of the pollutant such as NOX and SO2 in addition, is an energy-efficient combustion system.
Oxygen-enriched combustion technology, all has application in glass industry, metallurgical industry and Thermal Power Engineering Field at present.
The oxygen-enriched burning device of prior art prepare oxygen-enriched after be generally required for carrying out heating oxygen-enriched, such energy
Enough improve oxygen-enriched temperature, and oxygen-enriched in moisture can become steam, if the steam in oxygen-enriched is not removed, oxygen-enriched enter
In entering combustor and after full combustion of fuel, after combustor cooling, in it, moisture can be left；And due to oxygen-enriched be continually
Ground enters combustor, it will usually cause oxygen excess, and the oxygen of excess does not the most participate in combustion reaction, and result is with flue gas one piece row
Go out, cause the biggest waste.
Summary of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, it is provided that a kind of pressure-variable adsorption oxygen-enriched combusting dress
Put.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme:
A kind of pressure-variable adsorption oxygen-enriched burning device, including pressure swing adsorption oxygen and combustor, also includes aerator, air
Filter, air heating apparatus, gas-liquid separator and carbon dioxide adsorption device, the air inlet of described pressure swing adsorption oxygen is even
Connecing air filter, the air inlet of air filter connects aerator, and the gas outlet of described pressure swing adsorption oxygen is connected to sky
The inlet of cold air of gas heater, the hot air outlet of air heating apparatus connects the air inlet of gas-liquid separator, and gas-liquid is divided
Be connected to the air inlet of combustor from the gas outlet of device, the exhaust opening of described combustor connects carbon dioxide adsorption device, and two
The gas outlet of carbonoxide adsorbent equipment is connected to the air inlet of aerator.
Further, in order to reduce oxygen-enriched waste, in the air inlet of described combustor, it is provided with back-pressure valve, enters combustion when oxygen-enriched
After burning indoor, the pressure in combustor is gradually increased, until the completely rear back-pressure valve of the oxygen-enriched collection in combustor can stop oxygen-enriched
It is again introduced into.
Preferably, described air heating apparatus is pipe heat exchanger.
Compared with prior art, pressure-variable adsorption oxygen-enriched burning device of the present utility model, by by negative-pressure adsorption oxygenerator
The oxygen heating laggard row gas-liquid separation prepared, makes pure oxygen enter combustor, and combustor is discharged flue gas and do not participates in combustion
The oxygen of burning reaction is again passed through in pressure swing adsorption oxygen after carbon dioxide adsorption device removes carbon dioxide and collects not
Participate in the oxygen of combustion reaction, this utility model simple in construction, save the energy.
