Detailed description of the invention
The embodiment of the present invention: make the direct combustion purification device of organic exhaust gas
Method is: shown in accompanying drawing 1, and waste gas passes through air inlet pipe 9 in the downward direction of arrow of the effect of blower fan 8, and laterally blows into diffuser 6 from blast cap 7 surrounding.At this moment the burner 4 in burner arm 5 has been lighted and has jetted out flames.Flame and waste gas are jointly through flameholder 3, under flameholder 3 acts on, part flame combustion high-temperature combustion product produces reflux movement (namely with carry out flow path direction contrary) as the constant ignition source with auto-compensation ability, constantly light the flammable mixture do not fired in waste gas, form stable combustion field 2, the flammable mixture in waste gas is burnt completely.Prolong the direction of arrow finally by blast pipe 1 to discharge.
Make the direct combustion purification device of organic exhaust gas; Shown in accompanying drawing 1 and accompanying drawing 2, device includes blast pipe 1, the smooth combustion field 2 formed when flammable mixture burns completely in waste gas, flameholder 3, burner 4, burner arm 5, diffuser 6, blast cap 7, blower fan 8, air inlet pipe 9.
Specific practice is: (1) chooses the long 1000mm of diameter 80mm, and the stainless steel tube of wall thickness 3mm is blast pipe 1, makes the flameholder 3 of a taper of the corrosion resistant plate that 1mm is thick, and to connect with one end of blast pipe 1 with suitable position and fix.(2) the liquefied gas flame gun selecting a nozzle diameter 50mm is burner 4, is fixed in burner arm 5 centre position of the section length of side 150mm equilateral triangle pipe made of the thick corrosion resistant plate of 1mm.(3) make the drum type of a diameter 600mm height 1000mm of 1mm corrosion resistant plate, prolong in this drum type appropriate location the equilateral triangle nibs that diameter opens two length of side 150mm, be welded and fixed with burner arm 5.Make diameter 600mm with the thick corrosion resistant plate of 2mm, the ring-like plate in diameter 80mm hole is opened at center, is welded and fixed the upper end of blast pipe 1 and drum type.Another same plate is welded and fixed the lower end of blast cap 7 and drum type, forms diffuser 6.(4) 1 typhoon amount of choosing is 1000m
3centrifugal blower, fan outlet and diffuser bottom plate opening are welded and fixed, and air inlet and the air inlet pipe 9 of blower fan are welded and fixed.
After device being completed by above way, as required air inlet pipe 9 is accessed in organic exhaust environment.Burner 4 is connected fuel gas source and lights, blower fan 8 switches on power simultaneously, and device is started working.At this moment, organic exhaust gas is inhaled into by air inlet pipe 9 under the effect of blower fan 8, enters diffuser 6 through blast cap 7.The flame that organic exhaust gas and burner 4 spray, jointly through flameholder 3, forms stable combustion field 2, prolongs the direction of arrow completely discharge after burning by blast pipe 1.
