Description

The limekiln is with the air-breathing beam of cooled
Technical field
The utility model relates to a kind of limekiln parts, the air-breathing beam of specifically a kind of limekiln cooled.
Background technology
Be provided with air-breathing beam in the limekiln, have air entry on the air-breathing beam and efflux mouth the high-temp waste gas in the kiln is absorbed and outwards discharging, owing to the lime kiln temperature is very high; Air-breathing beam all is in the condition of high temperature in the working time; Service life is shorter, every two years just needs to change once air-breathing beam, both wasting manpower and material resources usually; Also have to take man-hour, ordinary production is impacted.For a long time, each manufacturing enterprise has to bear the annual negative consequence of changing air-breathing beam several times.
The utility model content
The purpose of the utility model just provides a kind of limekiln with the air-breathing beam of cooled, to solve existing air-breathing beam short problem in service life.
The utility model is achieved in that cooled air-breathing beam in limekiln comprises air-breathing beam inner core and is socketed in the outside cooling air duct of said air-breathing beam inner core; Have air entry in several on the said air-breathing beam inner core; Cooling have on the air duct with said in the corresponding outer air entry of air entry quantity and position, between said interior air entry and the outer air entry through at air-breathing beam inner core with cool off that the air intake duct in the interlayer joins between the air duct; Termination at said cooling air duct has cool air hose, on said cool air hose, is connected to air-cooler; The other end at said cooling air duct is connected to discharge pipe.
The air-breathing beam of this cooled is installed on inside, limekiln; High-temp waste gas in the kiln is also discharged through outer air entry, air intake duct and interior air entry inhale beam inner core; Cooling blower is blown into cold wind through cool air hose in the cooling air duct; Flow in the interlayer of this cold wind between air-breathing beam inner core and cooling air duct; Can be simultaneously cool off, thereby reduce both temperature simultaneously the barrel of air-breathing beam inner core and the barrel of cooling air duct, so effectively improve in the kiln with air-breathing beam inner core in hot environment to the damage of cylindrical shell.This air intake duct that is positioned at the mobile interlayer of cold wind that air-breathing beam designed had both played the supporting role to air-breathing beam inner core, simultaneously, improved cold wind to the cooling-down effect of air-breathing beam inner core with the cooling air duct thereby also played the effect that is similar to fin.
The air-breathing girder construction of the cooled that the utility model designed is simple; Owing to need not to change the outer shape and the overall dimensions of original air-breathing beam; Therefore, when the air-breathing beam of the cooled of this structure uses on existing limekiln, need not the limekiln internal structure is made any change; Can install smoothly, also can not have the problem of the sealing state that destroys the limekiln.The significant prolongation in service life of this air-breathing beam.But continuous operation need not to change for many years, has both saved human and material resources, has avoided again having solved a difficult problem that perplexs each manufacturing enterprise for a long time because of changing the economic loss that air-breathing beam is stopped work and brought.In addition, the cold wind in the cooling air duct absorbs the heat energy of high ambient temperatures environment, can send in the stove at the hot blast that air outlet obtained; Carry out second use as combustion adjuvant; Also realize the recycling of the contained heat energy of high-temp waste gas thus, thereby reduced energy waste, improved the business economic benefit.
The utility model optimized technical scheme is: the outer surface at said air-breathing beam inner core has the discrete axial V-type vortex groove of multiple row; On the inner surface of said cooling air duct, be shaped on the helical form flow-disturbing wall of coiling vertically.The helical form flow-disturbing wall that designs in the cooling air duct of this air-breathing beam makes the cold air of axially carrying form spiral air flow.This spiral air flow between inner/outer tube in the less ring-type mezzanine space is through each V-type vortex groove of tube outer surface in the air-breathing beam time; Further form eddy current; Thereby further improve heat exchange efficiency; And then make the cylindrical shell cooling-down effect better, and make that also the hot blast temperature of air outlet is higher, more help heat energy and second use.
The preferred technical scheme of the utility model is: the cross section of said V-type vortex groove is that the length of side is the equilateral triangle of 4-5mm; The height of said helical form flow-disturbing wall is 5mm.Adopt the design, surplus said air-breathing beam reaches 40,000 service life hour, but continuous operation 5 years and need not changing efficiently solves the practical problem in the enterprise production.
