The Chinese invention patent application of application number 201110297714.X proposes " the combined furnace arch structure in biomass fuel chain boiler; comprising: chimney arch before the antetheca of boiler furnace is provided with the parabolic shape projecting inward to burner hearth; the lower end of the inclination chimney arch be obliquely installed is connected to the bottom position of burner hearth rear wall; the upper end of inclination chimney arch is connected with the horizontal segment of " L " shape chimney arch, and " L " shape chimney arch and inclination chimney arch form the rear chimney arch of boiler jointly; Before parabolic shape, chimney arch and the upper vertical parts of " L " shape chimney arch and the side wall on burner hearth both sides form the combustion chamber of boiler, and the side wall on inclination chimney arch and burner hearth both sides forms the secondary furnace of boiler.The advantage of this invention is: before parabolic shape, the radiation heating effect of chimney arch can make biomass fuel separate out rapidly a large amount of volatile matters, further promotes the hi-temp hi-effective burning of fugitive constituent in combustion chamber.One of them object of this invention makes combustion chamber regions temperature high, material burning completely, improve efficiency of combustion, but defect is that chamber temperature is higher, inclination chimney arch is also that burning cover is in high-temperature flue gas region for a long time, chimney arch material will there will be aging hastening phenomenon, have a significant impact the safety and reliability of burning cover.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of high-temperature incinerator burning cover air curtain protection system.
The present invention is achieved by the following technical solutions: a kind of high-temperature incinerator burning cover air curtain protection system, comprise cooling air pressure fan and cooling-air spout, cooling air pressure fan is connected with cooling-air spout by cooling air air supply duct, it is characterized in that: cooling-air spout is arranged on the furnace wall of incinerator, be close to the below of burning cover and contact site, furnace wall, cooling-air spout is made up of reducing and nozzle, nozzle is flat nozzle, reducing is funnel-form, the major part of reducing is connected with cooling air air supply duct, the microcephaly of reducing is that flat is connected with nozzle.
As further improvement of these options, cooling-air spout has 6,3 cooling-air spouts are respectively arranged in the arranged on left and right sides furnace wall contacted with burning cover, and on every wing furnace wall, spontaneous combustion cover end arranges a cooling-air spout in 1/8,3/8,5/8 burning cover length place backward along burning cover incline direction.
As further improvement of these options, also comprise industrial computer and frequency converter, frequency converter connects cooling air pressure fan and industrial computer.
As further improvement of these options, in burning cover, arrange thermocouple, thermocouple has 6 different parts being distributed in burning cover, and thermocouple is connected with industrial computer.
The present invention has the following advantages compared to existing technology:
(1) according to the characteristic of incineration firing, the lengthwise position of cooling-air spout is arranged in the high position of combustion zone temperature, height and position is arranged in is close to burning cover bottom.After burning cover temperature is higher than design temperature, be blown into cooling-air, form Cryogenic air protective cover, reduce burning cover temperature and protection burning cover material.
(2) control of blower fan air output is realized by industrial computer and frequency converter, and burning cover radiating surface temperature both can have been prevented too high, too can not reduce chamber temperature again, impact burning is with the decomposition of bioxin.
(3) air that cooling-air spout is blown into can provide oxygen enough in combustion chamber, such energy reduces the air capacity sent into bottom chain grate boiler, avoid in incineration firing process, because Cryogenic air sends into generation coking and slagging phenomenon from bottom.
