Description
The utility model belongs to the adjustable rusting of high viscosity air oil proportional flame and chews.
Along with Petroleum refining develops to deep processing, the heavy residual oil after PETROLEUM PROCESSING is refined improves day by day as the viscosity of Industrial Stoves fuel.Domestic heavy residual oil Engler viscosity E by the sixties
0 100About 10～15 bring up to E now
0 100=40～60.Originally Industrial Stoves burn and chew generally by work viscosity E
0=4～6 designs can not adapt to the atomizing of high-viscosity heavy residue, cause atomizing particle thick, and burn deterioration easily bumps the furnace wall wall.Existing burning is chewed when load change simultaneously, and wind oil is regulated disproportionate, causes excessive flue gas loss increase of air quantity or the too small anoxycausis over-emitting black exhaust of air quantity.Because it is disproportionate that wind oil is regulated, the microcomputer automatic control technology is difficult to use in Industrial Stoves and promote, and therefore presses for the new burning of development and chews.
The purpose of this utility model provides the adjustable rusting of a kind of high viscosity air oil proportional flame and chews.
Elaborate below in conjunction with accompanying drawing.
Accompanying drawing is that schematic diagram is chewed in the adjustable rusting of high viscosity air oil proportional flame.
This burning is chewed to have to burn and is chewed body (14), burning is chewed body hollow, and an end is provided with flange, an end syzygium samarangense gas hood shell (16), the atomizer case is provided with disk of conical profile (2) outward, burning is chewed and is provided with successively oily valve sleeve (9) in the body, and fuel tap stick harness (8) is provided with oil duct in the oily valve sleeve, burning is chewed intracoelomic cavity wall and fuel tap cover for seat drum outer wall looping air flue, oil valve sleeve one end is provided with ring grease chamber (10), and a termination oil is chewed (3), atomization mass (1). Have wedge-shaped slot on the fuel tap stick harness, a termination has spiral to pay (11), adjusting handle (12). Burning is chewed body flange side direction and is had oil-in (7), air inlet (vapour) mouthful (13), and oil-in communicates with oil duct through the ring grease chamber, and air inlet (vapour) mouth communicates with annular air channel. Burning is chewed external air door inner sleeve (4) and the air door outer sleeve (5) that is nested together that be provided with, the air door outer sleeve is connected by wind oil interlock connecting rod (6) with the fuel tap stick harness, the air door inner sleeve is provided with triangle wind gap, burns and chews the external shell (15) that is provided with. Be provided with the combustion air chamber therebetween, and communicate with the combustion air import.
Form air oil proportional regulating device by air door inner sleeve, air door outer sleeve, fuel tap stick harness, oily valve sleeve, wind oil interlock connecting rod etc. Form flame adjustable device by portable disk of conical profile and shell front end inner conical surface. By burning chew, atomization mass, disk of conical profile form the high viscosity atomizer. When amount of fuel is 0～120Kg/h, capacity is when 0～30Kg/h, oil is chewed and is-gradually expanded form, throat diameter is 3mm, capacity is during greater than 30Kg/h, and oil is chewed the multi-head spiral groove into rectangle, and the atomizing body wall is provided with inscribe (cutting) gas (vapour) power orifice, the disk of conical profile outside is provided with the eddy flow groove, and three's eddy flow direction is consistent.
Fuel oil imports the oil ring chamber through oil-in, on the fuel tap stick harness wedge-shaped slot is arranged, constitute oily flow control valve with fuel tap cover for seat tube, the position that changes fuel tap stick harness (8) and fuel tap cover for seat tube just can change the size of amount of fuel, fuel oil flows into oil through the fuel tap stick harness and chews, chew for chewing oil less than the burning in 30Kg oil/time, throat diameter is equal to or greater than 3 millimeters, thereby fuel oil is difficult for stopping up, oil is chewed gas (vapour) the power vortex spray chamber that outlet constitutes for gas (vapour) power atomization mass, atomizing medium drives the fuel oil rotation from cutting (cutting) to entering gas (vapour) power vortex spray chamber, fuel oil is evenly distributed at gas (vapour) power vortex spray chamber, form the ejection of rotation mist torch, obtain atomizing for the first time, chew for burning greater than 30Kg oil/time, oil is chewed and is made bull rectangular coil groove, rotation direction is identical with gas (vapour) power vortex spray chamber, fuel oil enters gas (vapour) power vortex spray chamber forms rotation under gas (vapour) power atomizing uniform atomizing torch ejection from bull rectangular coil groove, intersect with the combustion air that produces equidirectional rotation through the taper fan blade, produce secondary-atomizing, thereby realized under high viscosity fuel, having obtained the atomized particle size of function admirable, atomizing average oil particle diameter SMD＜50 microns.
It is to be realized by air door inner sleeve and air door outer sleeve that air quantity is regulated, the air door inner sleeve is provided with the air port of many triangles, under the covering of air door outer sleeve, the relative position that changes air door outer sleeve and air door inner sleeve has just changed and has entered the air quantity that burning is chewed, and the relative displacement of air door outer sleeve and air door inner sleeve and air quantity be varied to linear relationship.
The displacement of fuel tap stick harness is passed to the air door outer sleeve by wind oil interlock connecting rod, changes fuel tap stick harness position and promptly just changes the oil mass size, and the position that has changed outer sleeve by wind oil gangbar has simultaneously also just changed the air quantity size, has realized that burning wind oil regulates in proportion.
The adjusting that burning is chewed combustion flame length is to realize by changing taper fan blade axial location, and the displacement forwards, backwards of fan blade position axis can change the ratio of eddy flow wind and direct current wind, can obtain the atomizing angle of different mist torches and different flame length.
It is wide that this burning is chewed the heavy residual oil range of viscosities of adaptation, and the work range of viscosities is Engler viscosity E
0=4～60, both applicable to high viscosity also applicable to low viscosity, atomizing elaioleucite average grain diameter SMD＜50 microns.Can realize the air oil proportional adjusting, it is good to regulate proportional linearity, can realize kiln burning control automatically more conveniently, and combustion flame length can be adjustable on demand.It is 0～120Kg oil/time that burning is chewed amount of fuel, is applicable to Industrial Stoves such as petroleum recovering district, petrochemical industry, metallurgy, machinery, pottery.
