Description
Technical field
The utility model relates to a kind of oxygen-enriched combustion-supporting device, the combustion-supporting associated plant of particularly a kind of dry-type film oxygen enriching.The utility model is applicable to the combustion-supporting equipment of using in the local oxygen enriching gradient combustion technology glass-melting furnace of dry-type film oxygen enriching, belongs to the energy-conserving and environment-protective equipment technical field.
Background technology
Air is the important ignition dope of fuel combustion, and oxygen content is about 21% in the air generally speaking, and nitrogen is about 79%, is in the combustion processes of ignition dope at air, and nitrogen is the rare gas element of fuel combustion.Therefore, adopt the oxygen-enriched combustion-supporting technology, be about to airborne a nitrogen content and reduce by 5%～20%; Combustion-supporting air quantity and combustion exhaust amount all reduce to some extent; Combustion velocity is accelerated, and the partial flame temperature improves, and not only can reduce the power loss of bringing because of the introducing of inert nitrogen gas in a large number; And, make SO in the flue tail gas because of the air total amount that gets into the combustion chamber reduces
2, NO
xConcentration improve, be convenient to follow-up desulfurization, denitration is handled.
The film oxygen enriching combustion supporting technology is to be higher than a kind of efficient overheavy firing technology of 21% gas as combustion-supporting gas with oxygen level, is characterized in that combustion-supporting air quantity and combustion exhaust amount all reduce to some extent, and combustion velocity is accelerated, and the partial flame temperature improves.Prove that through research and experiment for many years film oxygen enriching combustion-supporting and energy-saving technology can not only make full combustion of fuel, optimizes the flame structure, improve quality product, and can also prolong the Industrial Stoves service life of equipment; Raising the output output; And the glass quality raising, furnace service life prolongs, and soot emissions are up to standard etc.; Just can regain fully invested in general 1 year, so have remarkable social benefit and economic benefit; Simultaneously owing to reduce the discharging of flue dust, dust and NOx and CO etc., thereby helping the purifying ecological environment protection, is one of cost-effective approach that reduces the NOx discharging.
Existing membrane oxygen enrichment technology mainly is to utilize the infiltration rate when each component sees through polymeric membrane in the air different, under pressure difference drives, airborne oxygen concentration is obtained the technology of oxygen-rich air.With Deep Cooling Method, change to press absorption method (PSA) to compare, but membrane oxygen enrichment technology has that simple, the easy to operate and safety of equipment, starting are fast, in the scale I, free from environmental pollution, less investment, characteristics such as energy-saving effect is remarkable, purposes is wide.What therefore generally use now is membrane oxygen enrichment technology.
In the membrane oxygen enrichment technology, improve flame temperature and reduce because of nitrogen amount, air capacity and exhaust gas volumn all significantly reduce, so flame temperature significantly improves along with the increase of oxygen proportion in the combustion air.Accelerate combustionvelocity, promote burning fully, thereby the combustionvelocity of radical cure pollution feul in air and in pure oxygen differs very big.So use oxygen-enriched combustion-supporting, can not only improve intensity of combustion, accelerate combustionvelocity, obtain thermal conduction preferably, and because temperature has improved, and it is complete to help combustion reactions, thereby fundamentally decontamination.Now generally use the combustion-supporting associated plant of dry-type film oxygen enriching to improve the oxygen content of combustion air in the membrane oxygen enrichment technology.The combustion-supporting associated plant of existing dry-type film oxygen enriching includes air cleaning filtration unit, input blower fan, membrane separation unit and oxygen enrichment and increases stable-pressure device; Also include the combustion-supporting tuyere arrangement that is arranged on the kiln; Also include vacuum pump; Wherein import between the inlet that blower fan is arranged on air cleaning filtration unit and membrane separation unit, the outlet of membrane separation unit increases stable-pressure device with oxygen enrichment after through vacuum pump and is connected, and oxygen enrichment increases stable-pressure device and is connected with combustion-supporting tuyere arrangement.The combustion-supporting associated plant of existing this dry-type film oxygen enriching exists following defective: (1) is owing to be provided with vacuum pump; This device is by blower fan air to be sent into membrane separation apparatus; With water ring vacuum pump the oxygen-rich air of per-meate side is collected, therefore this device method of carrying out oxygen-enriched combustion-supporting also is referred to as negative pressure flow process film system oxygen.Because water ring vacuum pump needs a large amount of soft water, a large amount of moisture content enters into oxygen-rich air through negative pressure and goes to participate in burning, does not only reach the purpose of oxygen-enriched combustion-supporting, takes away heat energy because of water evaporates on the contrary and has reduced furnace temperature.So the oxygen-enriched combustion-supporting weak effect, energy-saving effect is undesirable, has caused cost high; (2) vacuum pump that uses in this associated plant generally adopts no oily oil-sealed rotary pump, exists energy expenditure big, the shortcoming that process cost is high.
