Description

The isotherm formula singeing fire hole

The utility model relates to a kind of burner of using on the gassing frame of textile dyeing and finishing of being used for.

Singing is the important procedure of textile dyeing and finishing.The process of singing be with fuel gas with after quantitative air mixes, eject combustion flame by burner, on whole work range with thermal-flame to the processing of singing of the surface of fabric, with impurity and the fine hair of removing fabric face, improve the quality of textiles.The gassing frame that uses both at home and abroad is mainly based on the flameless burner of slit burner with the band firebrick at present.Wherein yielding, the incomplete combustion in slit burner ubiquity slit, Fuel Consumption are big, problem such as Flame Temperature Distribution is inhomogeneous.

The purpose of this utility model provides a kind of sufficient combustion, the uniform isotherm formula gassing frame of Flame Temperature Distribution burner.

For achieving the above object, the technical scheme of isotherm formula singeing fire hole described in the utility model is as follows: this isotherm formula singeing fire hole, comprise air inlet pipe, burner housing and the spindle nose that connects air inlet pipe and burner housing, the burner housing comprises left shell and right shell body two parts, left and right sides housing relative fixed connects, form first mixing chamber, second mixing chamber that communicates with first mixing chamber, the combustion chamber that communicates with second mixing chamber and clearance type spout, have the round mixing tube that communicates with air inlet pipe in first mixing chamber; Have heater in the spindle nose, have the heating tube that communicates with heater in the round mixing tube.

In order further to improve burning quality, gas is mixed more fully, and improve the current stabilization degree of gas.Heater design can be become the helix tube type heater, fuel gas produces eddy flow by heater surfaces the time, not only can improve the temperature of gas, helps fuel gas and Air mixing and current stabilization simultaneously.

After adopting above technical scheme, fuel gas at first through the heater heating, improves the temperature of fuel gas before entering the burner burning; After entering the burner enclosure interior, fuel gas successively repeatedly collides mixing in first mixing chamber, second mixing chamber, combustion chamber, make fuel gas fully mix with air, thoroughly gasify, at last by the ejection of clearance type burner, burning, flame temperature is even, sufficient combustion.

Further specify the utility model below in conjunction with the drawings and specific embodiments:

Fig. 1 is the elevational cross-sectional view of this isotherm formula singeing fire hole;

Fig. 2 is the side view cutaway drawing of this isotherm formula singeing fire hole.

As shown in Figure 1 and Figure 2, this isotherm formula singeing fire hole, comprise air inlet pipe 1, burner housing 3 and the spindle nose 2 that connects air inlet pipe 1 and burner housing 3, burner housing 3 comprises left shell and right shell body two parts, left and right sides housing relative fixed connects, prismatic combustion chamber 6 and clearance type burner 7 that middle cavity forms first mixing chamber 4, second mixing chamber 5 that communicates with first mixing chamber 4, communicates with second mixing chamber 5; Have the round mixing tube 9 that is communicated with air inlet pipe 1 in first mixing chamber 4, the two ends of this round mixing tube 9 are separately fixed at the two ends of burner housing 3, and the tube wall of round mixing tube 9 has three rows and is mutually the downward through hole of certain angle; Have helix tube type heater 8 in the spindle nose 2 of connection air inlet pipe 1 and burner housing 3, this heater 8 is introduced from an end spindle nose, and the middle straight tube portion is drawn from other end spindle nose by the round mixing tube, and is separately fixed on two spindle noses; The passage that first mixing chamber 4 and second mixing chamber 5 communicate is three exhausting holes that are mutually certain angle that surrounded by left and right sides housing, wherein the axis of Zhong Jian a exhausting hole passes through the axis of first mixing chamber 4 and second mixing chamber 5, in addition angled with it the and left-right symmetry of two exhausting holes; In second mixing chamber 5 and passage that prismatic combustion chamber 6 links to each other, have spiral current stabilization rod 10, this spiral current stabilization rod 10 is surperficial screwed rifle bars that the cross section is " C " shape, its breach is towards prismatic combustion chamber 6, and having the cross section on the breach is "T"-shaped "T"-shaped constant-current pad 11; The temperature of clearance type burner 7 when reducing work, the both sides that can also be positioned at prismatic combustion chamber 6 on burner housing 3 are provided with cooling water channel 12 near the place of clearance type burner 7, wherein pour into cooling circulating water.

During work, the porch of heater 8 connects the cycling hot steam valve, fuel gas is imported by air inlet pipe, flow through inside when being connected with the helix tube type heater 8 of heat steam, temperature can be brought up to Celsius 60 and spend to 80 degree, do preliminary the mixing according to the rotation direction of heater 8 simultaneously, produce the air-flow of rotation at a high speed, pour in the round mixing tube 9, and three exhausting holes of its bottom of process enter first mixing chamber 4, since three exhausting holes on the round mixing tube 9 be open downwards and the outlet of first mixing chamber 4 in the above, so air-flow certainly leads to violent collision after entering first mixing chamber 4, carry out large-scale energy exchange and counterdiffusion mutually, improve gasification rate, accelerate the gasification process; Fuel gas enters second mixing chamber 5 through three prescriptions that are positioned at its top to the through hole that intersects after first mixing chamber 4 mixes, mix again, gasify, and reaches the well-mixed state that is gasified totally basically; When the thread pitch of the fuel gas of vaporized state by spiral current stabilization rod 10 enters prismatic combustion chamber 6, spiral passage can play the current limliting voltage stabilizing, reduce turbulent flow, the effect that refinement distributes, after two strands of fuel gas on the surface by spiral current stabilization rod 10 enter prismatic combustion chamber 6, effect via "T"-shaped constant-current pad 11, according to the shape of prismatic combustion chamber 6 within it portion collide mixing mutually, form two equivalent hot reflux districts of triangle tangential distribution in the edge, in the recirculating zone, part combustion gas forms the burning rapidly of fire point back, by 7 ejections of clearance type burner, another part still continues to revolve mixed, and storage power is accelerated heat exchange; Fuel gas replenishes, revolves under the dynamic equilibrium condition mixed, that burning sprays this, automatic stabilisation jet state, the isothermal flame of formation relative equilibrium.

The setting of cooling water channel and the cooling effect of cooling water can make clearance type burner 7 keep relative temperature the end of than, avoid the slit distortion of burner.

Isotherm formula singeing fire hole of the present utility model goes for various energy resources such as gasoline, natural gas, town gas, liquefied petroleum gas, has identical effect.
