Description
Technical field
The invention belongs to a kind of glass tempering furnace heating air exhausting device, relating to a kind of air draft convection device for processing during LOW-E glass tempering furnace.
Background technology
The hot spots of current glass tempering furnace generally includes upper furnace, lower hearth, middle live rollers, process furnace silk etc.When pending LOW-E glass moves in process furnace, top process furnace silk and below process furnace silk heat simultaneously, due to LOW-E glass coating structure, the surface temperature of below nichrome wire can more than 800 degree time heating furnace temperature when reaching 680 degree, the surface temperature of top nichrome wire can more than 800 degree.This one side of glass for LOW-E glass (usually down) is normal, but for cated one side, such temperature major part coated of heat reflected, such result makes the side of coat side can not reach 680 degree at all, and namely allowing to reach can not be synchronous with glass side temperature below.The surface that these heat energy act on rete makes rete local location overheated, cause as rete burn out, buckling deformation, bottom scratch etc. series of problems.
LOW-E glass, at glass tempering furnace produced problem, makes people have reason to design a kind of external device, forces furnace air convection current, to balance the annealing furnace temperature difference.
The existing air draft convection device for processing LOW-E glass tempering furnace, that air draft convection current is divided into hot air passage and cold airduct, what enter in hot air passage is hot gas in annealing furnace, cold airduct injects low temperature compression gas, low temperature compression gas enters from the entrance of interchanger, circulates in heat exchanger tube; What hot gas entered is heating container, and interchanger is in hot bellows, and hot gas to circulate outward operation at interchanger.
Device comprises jet pipe 7, heating container 8, heating container hot-blast outlet 9, heating container hot-wind inlet 10, interchanger 11 in high pressure positive blower 1, compressed air inlet 2, compressed air inlet 3, middle live rollers 4, lower hearth 5, process furnace silk 6, stove.
In heating container, interchanger is set, external compression gas inlet connect heat exchanger entrance, notify after heat exchange in interchanger heat exchanger exit enter be arranged at upper furnace stove in jet pipe; In stove, the outlet of jet pipe is positioned at the upper furnace of annealing furnace, if be equidistantly open along upper furnace surrounding in annealing furnace open aperture.
The one end open of hot wind inlet is in heating container, and the other end is opened in the upper furnace of process furnace.High pressure positive blower is directly connected on heating container.Hot blast in annealing furnace two hot wind inlet enter heating container, discharge after interchanger at interior heating container through high pressure positive blower;
The design of existing air exhausting device, hot-blast outlet end needs to arrange high-power blower guarantee hot gas and can discharge in time.But due to cannot timely and effectively injecting of low temperature compressed air, the temperature equilibrium in stove needs to prepare for a long time.And due to the high hot blast in tempering body of heater only some heat consumed at heat exchanger section, most heat energy is discharged in air in vain to be slatterned.And the high-power blower of hot-blast outlet is due to huge noise, also has a strong impact on Working environment, in today of pay attention to day by day production environment, more and more do not meet the requirement that science is produced.
