Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of heat exchange structure of safe, energy-conservation, free of contamination utilizing waste heat of glass furnace boiler.
Technical solutions of the utility model are: a kind of heat exchange structure of utilizing waste heat of glass furnace boiler, the air intake duct group comprising housing and be horizontally placed in genesis analysis in housing and air escape pipe group, described housing sidewall is provided with air intake duct group air inlet with air intake duct group correspondence position, air escape pipe group gas outlet is provided with air escape pipe group correspondence position, described case top is provided with smoke inlet, bottom is provided with exhanst gas outlet, described air escape pipe group gas outlet is communicated with glass melter, described air intake duct group outlet side is communicated with air escape pipe group inlet end.
Further, described air intake duct group and air escape pipe group include and to be vertically set in parallel in housing and the plate-shaped carrier that is fixedly connected with inner walls of periphery and lamination are fixed on Multi-row pipeline between plate-shaped carrier, every row pipeline comprises many tubules of horizontal homogeneous distribution, described plate-shaped carrier plate face is provided with the aperture be connected with tubule, gap is provided with between described tubule and tubule, described smoke inlet is communicated with by this gap with between exhanst gas outlet, forms flue gas heat exchange passage.
Further, the plate-shaped carrier of described air intake duct group outlet side and the plate-shaped carrier of air escape pipe group inlet end are positioned at housing homonymy, and and be provided with cavity between inner walls, this cavity forms the air channel that in air intake duct group and air escape pipe group, gas flows.
Further, blower fan is connected with between described air escape pipe group gas outlet and glass melter.
Further, described air intake duct group is positioned at below air escape pipe group.
The beneficial effects of the utility model: using air as heat transferring medium, the air preheater of normal pressure is utilized to ban traditional high pressure except oxygen evaporator, and by the pipeline of the only tubule of many merchandisers as transport heat transferring medium, even if some tubules are corroded by low-temperature flue gas, also the flowing of other thin inner air tube can not be affected, therefore equipment can not be caused to stop transport, eliminate the potential safety hazard of waste heat boiler.Air intake duct group and air escape pipe group are made up of many tubules, large with the contact area of low-temperature flue gas, good effect of heat exchange; It is combustion-supporting that air sends glass melter back to after the heat absorbing low-temperature flue gas, reduces the loss of fuel, economize energy.Adopt the waste heat boiler cycle of operation of this heat transmission equipment long, waste heat recovery efficiency is high, heat transmission equipment less investment, good in economic efficiency.Desulphurization and denitration, the cleaner of follow-up flue gas are stable, and flue gas qualified discharge, environmental benefit is obvious.
