Technical field
The present invention relates to a kind of glass chemistry toughening stove, be specially a kind of heat energy recycling formula glass chemistry toughening stove based on phase-transition heat-storage principle.
Background technology
At present, in the glass tempering furnace of industrial application, because chemical toughening furnace has superiority than physical toughened stove and accessory, be more widely accepted utilization.The chemical tempering of glass is glass to be placed in to the alkali salt of melting, make the larger ion-exchange of radius in ion that in surface layer of glass, radius is less and fused salt, finally on two surfaces of glass, form compressive stress layer, inside at glass forms tension stress layer, reaches the object that improves glass machinery intensity and resisting temperature impact property.Compared with physical toughened glass, chemical tempering technology has overcome the shortcoming of wind tempering technology, and the strength of glass that processes is high, Heat stability is good, surface is indeformable, can do suitable cutting process, without self-destruction phenomenon, when improving strength of glass, do not affect optical property at all.And the required tempering temperature of physical toughened stove generally at least will reach 700 ℃, and the required tempering temperature of chemical toughening furnace is greatly about 500 ℃ of left and right.Comparatively speaking, the hear rate of chemical toughening furnace can be lower.
But chemical toughening furnace is also to belong to highly energy-consuming product, it needs to consume a large amount of heat energy in process of production, and how rationally effectively to utilize the used heat producing in process of producing product is extremely important environmental protection subject.At present, the research of all kinds of chemical toughening furnaces aspect heat recovery is less, and accordingly, developing a kind of annealing furnace with function of recovering waste heat is one of glass industry aspect problem demanding prompt solution.
Summary of the invention
The invention provides the heat-circulation type glass chemistry toughening stove based on phase transition heat accumulation unit, the chemical toughening furnace of prior art is improved, make that the heat of this annealing furnace is capable of circulation to be used again.
The technical scheme that the present invention realizes is as follows: the heat-circulation type glass chemistry toughening stove based on phase transition heat accumulation unit, comprises airtight process furnace, phase change heat accumulator and extractor fan; Described process furnace is provided with blast inlet and exhaust outlet; Described phase change heat accumulator and extractor fan are connected to by blast tube between the blast inlet and exhaust outlet of process furnace, form the closed type recycle system; Near the blast inlet of described process furnace, be also provided with the branch row airduct with the exterior of the closed type recycle system, described branch row airduct is provided with vent valve; Described phase change heat accumulator at least comprises housing and phase-change heat accumulation element.
Preferably, the housing of described phase change heat accumulator is that lagging material forms.
A kind of preferred structure is that described phase-change heat accumulation element is for several phase change heat storage material plate that laminar is arranged.Phase change heat storage material plate is comprised of by arrayed mode or staggered pattern some phase-transition heat-storage pipes; Described phase-transition heat-storage pipe is for consisting of heat-conducting metal housing parcel phase change heat storage material.Further, be also provided with some windsheilds in described heat regenerator, described windsheild and phase change heat storage material plate are cross arrangement, and form " Z " type air channel.
Another kind of preferred structure is that described phase-change heat accumulation element is grid-like phase-transition heat-storage pipe.Further, be also provided with some windsheilds in described heat regenerator, described windsheild and phase-change heat accumulation element are alternating expression and arrange, also form " Z " type air channel.
In phase change heat accumulator, increase windsheild, be more conducive to extend the currency of gas in phase change heat accumulator, be conducive to gas and phase-change heat accumulation element heat exchange.
The present invention has adopted the combination of phase change heat accumulator and glass chemistry toughening stove, during annealing furnace annealing, hot gas in process furnace is extracted out, and the exhaust valve in close fork air channel, hot gas is circulated in the closed type recycle system, when hot gas passes through phase change heat accumulator repeatedly, waste heat is absorbed by phase-change heat accumulation element and saves; After gas cooling, then open vent valve and make other eliminatings.When annealing furnace need to heat, first open vent valve, in the freezing air suction closed type recycle system, after close vent valve, gas enters the heat of savings while absorbing annealing furnace annealing in phase-transition heat-storage, then enters heating in process furnace.So, by waste heat savings, the process that discharges, reached the effect of annealing furnace waste heat recovery recycle, the advantage of there is environmental protection, resource recovery, minimizing energy consumption, enhancing productivity.
Further, the phase change heat accumulator that the present invention adopts, has any different with traditional phase change heat accumulator, and traditional phase change heat accumulator is most arranges phase change heat storage material for direct fluid pipe is set outward at direct fluid pipe, when liquid motion, absorbs or release of heat; Phase change heat accumulator of the present invention is the open Heat Room of gas, the phase-change heat accumulation element that several are arranged by certain way is set in the body of chamber, the contact area that gas enters into phase change heat accumulator and phase-change heat accumulation element is the several times of legacy equipment, in the situation that contact area increases, the efficiency of gas converting heat is also the several times of legacy equipment.
In sum, beneficial effect of the present invention is: have the function of annealing furnace waste heat recovery regeneration, and the efficiency of waste heat recovery and recycling is high, has that device structure is simple, production cost is low, environmental protection, raising waste heat recovery efficiency, reduce and produce power consumption, the texts of enhancing productivity.
