Abstract
The invention aims at providing a high-efficiency and energy-saving hot-blast furnace top heat exchanger which is of a novel plate-type structure and matched with the hot-blast furnace, and relates to all hot-blast furnace top portion plate-type circulation heat exchangers. The furnace top heat exchanger comprises longitudinal cold air heating channels, longitudinal flame smoke channels, transverse smoke channels, transverse cold air heating channels, outer sealing plates, a smoke outlet, a hot-blast outlet and cooling fins.
Description
Technical field
The invention belongs to high-efficiency energy-saving technology field, relate to the board-like circulation heat exchanger in all hot-blast stove tops.
Background technology
Existing hot-blast stove top heat exchanger major part adopts pipe heat exchanger, has that heat exchange area is little, welding termination is yielding, a problem such as many easily stifled, inconvenient maintenance of flame soot.
Summary of the invention
The object of this invention is to provide the energy efficient hot air furnace furnace roof heat exchanger of the supporting brand-new plate-type structure of a kind of hot-blast stove, relate to the board-like circulation heat exchanger in all hot-blast stove tops.It comprises: 1. longitudinal cold air heating air duct, 2. longitudinal flame flue, 3. horizontal flue, 4. horizontal cold air heating air duct, 5. outer shrouding, 6. exhanst gas outlet, 7. hot-blast outlet, 8. fin.
Described longitudinal cold air heating air duct becomes square column type with sheet metal bent, inner chamber welding fin and the passage preheating cold air separated with flue.
Plate-side plate welding before and after longitudinal cold air heating air duct is connected by described longitudinal passage of flame exactly, centre reserves a fixed gap and walks the passage of cigarette for flame, and flame longitudinal cold air heating air duct outer panel that directly burns makes it be subject to heat trnasfer by longitudinal cold air heating air duct inner chamber air heat.
Described horizontal flue refers to and is laterally arranged on furnace roof upper end, and flue laterally passes through and heats the horizontal flue that this outer panel makes it be heated to pass to fin to be heated by cold air outside horizontal cold air heating air duct.
Described horizontal cold air heating air duct refers in furnace roof upper end sheet metal bent squarely, passes in and out the air channel of heating before and after the confession cold air of the soldered fin of inner chamber.
Described outer shrouding is shaped longitudinal cold air heating air duct to be connected with horizontal cold air heating air duct, longitudinal flame flue and horizontal flue are connected with skin separate every shrouding, be also simultaneously exterior baffle.
Described exhanst gas outlet refers to that furnace flame is through the exhanst gas outlet of longitudinal flame flue to horizontal flue end.
Described hot-blast outlet refers to that cold air becomes the air outlet of thermal air current through longitudinal cold air heating air duct to the heating of horizontal cold air heating air duct.
Described fin is welded on metal strip sheet the metal fin in longitudinal cold air heating air duct and horizontal cold air heating air duct, the heat absorbing flue being distributed heating cold air.
Accompanying drawing 1 is the board-like circulation heat exchanger schematic diagram in hot-blast stove top
In figure: 1. longitudinal cold air heating air duct, 2. longitudinal flame flue, 3. horizontal flue, 4. horizontal cold air heating air duct, 5. outer shrouding, 6. exhanst gas outlet, 7. hot-blast outlet, 8. fin.
Claims (2)
