Abstract
An isobaric type diesel combustor comprises an inner compressed air tube and an outer oil tube sleeved outside the inner compressed air tube, wherein two ends of the inner compressed air tube extend out of the outer oil tube; one end of the inner compressed air tube is connected with a diameter-variable inner compressed air tube, the diameter of the diameter-variable inner compressed air tube is larger than that of the inner compressed air tube, and an oil passing hole is arranged on the diameter-variable inner compressed air tube; one end of the outer oil tube is connected with a diameter-variable outer oil tube sleeved outside the diameter-variable inner compressed air tube, and the diameter of the diameter-variable outer oil tube is larger than that of the outer oil tube; sealing end covers are arranged on the end portions of the diameter-variable inner compressed air tube and the diameter-variable outer oil tube, and ejecting holes communicated with the diameter-variable inner compressed air tube are arranged on the sealing end covers. The isobaric type diesel combustor is simple in structure, easy to control due to the fact that no oil gas proportion adjusting valve is installed and capable of stably supplying compressed air to atomize diesel, and enables the diesel atomizing effect to be stable, an incinerator is stable in combustion, protective halt and flameout of the incinerator can be prevented, temperature fluctuation of the incinerator is small, and the combustor is safe and reliable to use.
Description
Technical field
The invention belongs to cigarette industry incinerator technical field of burner, particularly a kind of Isobaric type diesel combustor.
Background technology
At the CO of production of cigarettes producer
2on tobacco expanding line, incinerator is using diesel oil as fuel, and diesel oil burns in the burner with after compressed air mixed aerosol, and the burning of atomizing effect to diesel oil is most important.The monitoring of incinerator and the control principle of diesel fuel burner are: when system possesses ignition condition, the liquefied gas being easy to burn first is lighted, the burning that liquefied gas flame after burning is atomized diesel fuel provides ignites, once ignite successfully, liquefied gas automatically shuts down Liquified gas control valve under the control of PLC; Through diesel oil normal combustion in incinerator of compressed air atomization, for system provides thermal source.For the sake of security, ignite at liquefied gas and burn and diesel oil normal combustion link, FCS flame detecting probe detection to flare up fire send to flame detector, signal is sent to PLC by flame detector, is monitored in real time the situation of change of flame by PLC.
The course of work of existing burner is: pressure is that the compressed air of 0.6MPa passes through from the burner cavity that diameter is 5mm, pressure is that the diesel oil of 0.4MPa ~ 0.7MPa enters from the burner exocoel that diameter is 12mm, and enter burner cavity by the aperture that two diameters on burner cavity wall are 1mm, diesel oil mixes mutually with compressed air, last is eject the hole of 2mm from burner head diameter, burns.In order to ensure atomizing effect, in pipe-line system, being provided with an oil-gas ratin control valve, controlling compressed-air actuated inlet pressure by the inlet pressure of diesel oil, remain diesel pressure 0.1Mpa larger than compressed air pressure.
Because external condition does not stop change, diesel control valve aperture changes all the time, causes the pressure of diesel oil to be also ceaselessly change.If oil pressure change is excessive; mechanical oil-gas ratin control valve does not catch up with the change of oil pressure; and oil-gas ratin control valve fault etc.; diesel oil atomization weak effect is caused in capital; the length of flame of diesel combustion and lightness is caused to change; flame detecting is popped one's head in and can't detect the existence of flame, finally cause the generation that protectiveness is shut down.In addition, due to incinerator burner part and control system aging, often be difficult to starting ignition problem, there is the situation being difficult to for 2 ~ 3 hours start sometimes, and incinerator is in operation and also often occurs unprovoked unexpected Quench, not only affect the quality of product, the waste of the energy can be caused again.
In sum, diesel pressure not stop to change be the main cause of burner atomizing effect difference, particular/special requirement when burner uses is the major reason of causing trouble.
Summary of the invention
The invention provides that a kind of structure is simple, diesel oil atomization is effective, flameholding and the Isobaric type diesel combustor that protectiveness is shut down and incinerator is flame-out can be prevented.
For achieving the above object, technical scheme of the present invention is: a kind of Isobaric type diesel combustor, and comprise compressed air pipe and the outer oil pipe being set in compressed air pipe outside, outer oil pipe is stretched out at compressed air pipe two ends; Compressed air pipe one end is connected with reducing compressed air pipe, and reducing compressed air pipe diameter is greater than compressed air pipe diameter, and reducing compressed air pipe is provided with oil-through hole; Outer oil pipe one end is connected with the outer oil pipe of the reducing being set in reducing compressed air pipe outside, and the outer tubing diameter of reducing is greater than outer tubing diameter; Reducing compressed air pipe and the outer oil pipe end of reducing are provided with end cover, and end cover is provided with the spray-hole communicated with reducing compressed air pipe.
Described oil-through hole is positioned at the link of reducing compressed air pipe and compressed air pipe.
The intracavity diameter of described compressed air pipe is 5mm, and the intracavity diameter of reducing compressed air pipe is 18mm; The intracavity diameter of outer oil pipe is 12mm, and the intracavity diameter of the outer oil pipe of reducing is 24mm; The diameter of oil-through hole is 1.5mm; The diameter of spray-hole is 2mm.
Sealing ring is provided with between described end cover and the outer oil pipe end face of reducing.
Compared with prior art, advantage of the present invention is:
1, the present invention includes compressed air pipe and be set in the outer oil pipe of compressed air pipe outside, outer oil pipe is stretched out at compressed air pipe two ends, compressed air pipe one end is connected with reducing compressed air pipe, and reducing compressed air pipe diameter is greater than compressed air pipe diameter, and reducing compressed air pipe is provided with oil-through hole, outer oil pipe one end is connected with the outer oil pipe of the reducing being set in reducing compressed air pipe outside, and the outer tubing diameter of reducing is greater than outer tubing diameter, reducing compressed air pipe and the outer oil pipe end of reducing are provided with end cover, end cover is provided with the spray-hole communicated with reducing compressed air pipe, its structure is simple, due to oil-gas ratin control valve need not be installed, easy control, air supply for atomized diesel fuel can stablize supply, make the atomizing effect of diesel oil good, can avoid because oil-gas ratin control valve lost efficacy or the excessive incinerator combustion instability caused of diesel pressure fluctuation, make incinerator flameholding, can prevent protectiveness shutdown and incinerator from stopping working, and incinerator furnace temperature fluctuation is little, safe and reliable.
2, the intracavity diameter of compressed air pipe is 5mm, the intracavity diameter of reducing compressed air pipe is 18mm, the intracavity diameter of outer oil pipe is 12mm, the intracavity diameter of the outer oil pipe of reducing is 24mm, as calculated, pressure 0.402 Mpa lower than the pressure of compressed air pipe import department all the time in reducing compressed air pipe exit, the condition of compressed air pressure 0.1Mpa lower than diesel pressure can be met, thus guarantee that the diesel oil increased in grease chamber can enter air chamber in increase smoothly and mix with compressed air, make diesel oil atomization effective, flameholding.
3, the diameter of oil-through hole is 1.5mm, and the impurity be retained in the diesel oil of fine filtering can be made to pass through smoothly, prevents blocking, and midway is extinguished because of burner blocking to avoid incinerator, and service condition is loose.
