Detailed description of the invention
Embodiment one
The polyploid waste gas of the present embodiment strile-backs burning recirculation furnace basic structure as depicted in figs. 1 and 2, the body of heater 10 of square-section is surrounded by insulation furnace wall 10-1, the side of this body of heater 10 arranges the disjunctor heating 2 with heat insulation wall, this body of heater 10 be arranged over furnace roof room 11 in communication, and be mounted with waste gas and strile-back pressure fan 8。Furnace roof room 11 is built with the breather 9 being derived between levelling。The two bottom sides of heating 2 disposes the circulating fan 7 that air inlet is relative each other respectively, the air outlet of two circulating fans 7 be respectively facing body of heater 10 and and body of heater two side bottom be provided with the discharge pipe 10-2 of interval air door 10-3 and connect。The contiguous top heating first side of body of heater 10 is provided with the backwind tube 10-4 of triangular-section, owing to heating 2 top higher than the top of body of heater 10 and extend above backwind tube 10-4 top towards body of heater 10, therefore backwind tube 10-5 connects with the top of heating 2 either directly through the return air hole 10-5 at body of heater 10 top, not only structure is simple and direct, and high insulating effect。The rustless steel combustor 4 that the side, middle part of heating 2 is connected equipped with proportion expression combustor 6 of jetting with outer horizontal by support 5, heat exchanger tube 13 horizontal-extending after being cased with undergauge outside this combustor 4, therefore this heat exchanger tube 13 is in surrounding the big footpath section of combustor 4 and the ladder tubular of horizontal-extending path section composition, thus heating by the exhaust gases and hot air heat exchange rationally being separated。The heating height between 2 respective column heats exchange of heat pipe 14 and heat exchanger tube 13 has the water conservancy diversion projection 10-6 of trapezoid cross section, it is possible to play the deflecting air ring effect around heat exchanger tube 13。Heat exchanger tube 13 connects with the one end of the horizontal row heat exchange of heat pipe 14 being positioned at heating 2 top away from one end of combustor 4, the other end of tubular heat exchanger 14 discharges the inlet communication of blower fan 1 by pipeline and the waste gas being placed on heating 2 top, this waste gas is discharged the outlet of blower fan 1 and is discharged by the airduct equipped with rustless steel recirculated water chuck, therefore the waste heat of waste gas after burning can be converted into hot water and be used。The strile-back import of pressure fan 8 of waste gas connects with furnace roof room 11, and the strile-back outlet of pressure fan 8 of this waste gas is connected to the big footpath fragment position of heat exchanger tube 13 respective combustion chamber 4 by adapter 3。
During work, the fuel of combustor ejection produces heat in burning Indoor Combustion, and the flame level that extends of burning is extended down to the path section of heat exchanger tube, and the steam after burning enters tubular heat exchanger。The air on heating head top is entered under the swabbing action of hot air circulation blower by backwind tube and return air inlet, first pass through the gap heat exchange of tubular heat exchanger, heat up around the peripheral heat exchange further of heat exchanger tube again, bottom of furnace body is sent into afterwards by hot air circulation blower, input in body of heater by discharge pipe, formed and workpiece is dried and keeps the uniform circulating air of furnace temperature。Meanwhile, the organic exhaust gas of painting workpieces drying course and the organic exhaust gas of levelling process volatilization before enter furnace roof room, strile-backd the annular space that pressure fan is evacuated between heat exchanger tube big footpath section and combustor by waste gas, effectively preheated in this space, then flow to the path section that heat exchanger tube extends, add extension flame fully to burn, be cracked into free of contamination carbon dioxide and hydrone, toxic emission blower fan finally discharge。
In a word, the present embodiment makes fuel add thermogenetic heat and is passed to furnace interior through hot air circulation blower filter, forms hot air circulation, makes furnace interior furnace temperature uniformity。Levelling room is after the furnace roof room still with uniform temperature tentatively preheats, and the organic exhaust gas produced with body of heater is delivered to heat exchanger tube big footpath section preheated by waste gas pressure fan of strile-bacing, then is incinerated discharge。
In addition to the implementation, this utility model can also have other embodiments。Such as, the annular region between the big footpath section 13-1 of heat exchanger tube and combustor 4 outer wall forms helical flow path, and adapter 3 tangentially accesses along the spiral of helical flow path with helical flow path, and therefore organic exhaust gas is more fully warmed-up by helical flow path, to reach the purpose more fully burned。All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within the protection domain of this utility model requirement。
