Description

Efficient energy-saving hot-blast stove
The utility model relates to a kind of energy efficient hot air furnace, belongs to heating equipment, is specially adapted to the every profession and trade oven dry, also can be used for green house of vegetables and industrial or agricultural, civilian heating.
Hot-blast stove in the past all is with heating steel pipe and steel plate, and conduction is gone to heat cold wind and produced hot blast by metal.No matter vertical or horizontal its volume of this class stove is all very huge, consume great deal of steel, and because the tube bank of most hot-blast stoves all is the version that adopts horizontally set, not only power consumption is high, the thermal efficiency is low, and flexural deformation collapse waist, distortion often appear after being heated, cause the life-span of stove very short, What is more, and not enough unexpectedly 6-8 must change overhaul in individual month.Give installation and transportation because of its huge body weight and bring very big inconvenience, above-mentioned in view of the situation hot-blast stove has further improved necessity.
The purpose of this utility model be to provide a kind of simple in structure, volume is little, in light weight, quick heating, thermal efficiency height, energy savings and great deal of steel, long service life, combined type are convenient to the energy efficient hot air furnace installing, transport and overhaul.
The purpose of this utility model realizes by the following technical solutions, form by stove seat, flue and fan housing, the inner chamber of described stove seat is the combustion chamber, fire grate places the bottom, the flower arch is located at middle part, top, combustion chamber, exocoel is the cold wind preheating cavity, and blast inlet is located at a side of cold wind preheating cavity, and safety valve places the sides adjacent of blast inlet; Flue, fan housing place on the stove seat successively, and the cavity that forms between the inboard of flue and fan housing is the heat radiation chamber, and heat pipe is circumferentially uniform along flue, and the heating end of heat pipe tiltedly puts in the inner chamber of flue, and the flue upper end links to each other with flue tube; Bottom one side of fan housing is provided with hot-blast outlet.
Described heat pipe axially be arranged in parallel from bottom to top along flue, until the flue upper end, is the α angle between its axis and flue axis, and the α angle is the 30-45 degree.
Circumferentially having eight branch air ports with the corresponding side of fire door edge on the flange of described stove seat.
Both sides at flue between described fan housing and the flue are arranged with wind isolation board from bottom to top, and extend to the shoulder position of contracting, flue top.
Described safety valve, it comprises the half of down inside and outside cover that all has ventilating opening, and wherein overcoat is fixed, and interior cover can rotate with respect to overcoat, with the opening and closing of fault ventilating opening, the end face of cover in explosion-proof film places.
The utility model compared with prior art, owing to what adopted that structure similar to boiler and mode of heating adorn is heat pipe, with the chemical working medium in it is carrier, under the driving of thermal source, make working medium gasification produce high-energy physics and change, cause rapid intensification, conduction of velocity is fast and be knockdown structure.So there is long-pending corpusculum light, overhaul advantages such as convenient than 10 tons of steel of same specification stove saving, 50% energy, thermal efficiency height, long service life, transportation, installation, implement simultaneously to be beneficial to and to apply easily.
