Description

The energy-efficient spray gun of clearance type

The utility model relates to the burner of a kind of not only combustible gas fuel but also combustible liquid fuel, is meant the energy-efficient spray gun of a kind of clearance type especially.

The burner form that existing various industrial furnaces are used is multiple, wherein can supply with pancake flame burning device all is to offer a row or multi-row parallel staggered porous aperture in the burner outlet end, owing to the reason on the structural design, burning gases fuel must adopt different burner ability operate as normal respectively with combustion of liquid fuel, and can not accomplish with same burner both burning gases fuel combustion of liquid fuel again.And use the burner of liquid liquid material, the distinct issues the most of its existence, be that phenomenons such as carbon deposit obstruction take place easily, promptly be in the terminal aperture of burner, easily to produce carbon deposit to stop up, and Chang Yi is in the coking of burner terminal surface carbon deposit, coking when serious resembles hangs a string hard stalactite, until burner can not work on.In addition, for general burner, usually all when the ratio because of oil pressure and air pressure differs big, it is worn-out to cause blocking screen mutually, even pour in down a chimney mutual string, and so-called negative reactive phenomenon appears, and performance is the most outstanding when especially using on the heating furnace in fields such as petrochemical industry, building materials.And the burner from external import is mainly adopted at present in these fields on some main equipments.But the problems referred to above also still exist on the import burner to some extent.Importer's outer burner not only needs foreign exchange and costs an arm and a leg, and uses overbearing airs, the oil product of inapplicable inferior quality, even it is more to produce fault, the carbon deposit coking is serious.Fact proved that its technical level is still limited.

For overcoming the deficiencies in the prior art, the purpose of this utility model, be provide a kind of atomizing effect good and be difficult for to stop up, not carbon deposit coking and be suitable for that the oil product scope is wide, burning velocity fast and flame rigidity is good, convenient operating maintenance and the dual-purpose energy-efficient spray gun of clearance type of combustible gas fuel oil.

Solution of the present utility model is as follows.It still includes shower nozzle, atomizer wicking, swirler, inner sleeve, outer tube and back seat, and its feature part is, offer the taper pod apertures that is connected successively in the shower nozzle from front to back, column is mixed spray orifice and conical nozzle, the shape of cross section of these hole tube passages is the length long and narrow formula slit aperture bigger than width, the duct that communicates with it that taper pod apertures the place ahead of shower nozzle is offered is built-in with atomizer wicking, leave medium channel between this duct inwall and the atomizer wicking, be provided with multistage spin chamber of ring-type and eddy flow groove (or hole) in the atomizer wicking, and axially offer the multistage conical pod apertures that is connected successively from front to back along it, cylindrical mixing spray orifice and conical jet pipe, but a jet pipe that is connected with cylindrical mixing spray orifice of final stage end is flat conical nozzle, be that its shape of cross section is the length long and narrow formula slit aperture bigger than width, and the taper pod apertures in the shower nozzle faces the outlet of this flat conical nozzle of atomizer wicking final stage end, the conical pod apertures of each grade of atomizer wicking also faces the outlet of the conical jet pipe of previous stage, both all form a passage annular space each other for they, atomizer wicking offer the swirler chamber that is connected with the conical pod apertures of prime foremost, at the indoor swirler that is equipped with of swirler, the swirler front end is fixed with and passes the perforate on inner sleeve and the back seat and stretch out pull bar outside back seat, and back end of tie rod portion sliding sleeve has the plug screw that spins mutually with back seat.

The utility model with said structure, in use with liquid fuel and Alevaire by corresponding duct on the back seat, introduce inner sleeve and outer tube respectively.Because atomizer wicking adopted multistage eddy flow, strengthen mixing jetting, so mix and atomizing effect good, can obtain a kind of burning velocity soon and the strong special pancake flame of flame rigidity.If change inner sleeve and outer tube into transfer the fuel gas simultaneously, can realize fuel gas buring, thereby accomplish that fuel-firing gas-firing is dual-purpose.

The utility model modern design, can extensively be suitable for the burning of various liquid fuels (as light oil, crude oil, heavy oil, residual oil, waste oil etc.) and gaseous fuel (as coal gas, natural gas, refinery gas etc.), energy-efficient, no negative reactive, the operating mode load regulation rate is greater than 1 to 10, and Alevaire consumption rate is about about 0.1, working stability, not carbon deposit coking, fault is few.Just in case mechanical admixture takes place in the spray gun to be stopped up, open the plug screw that the back seat end spins, take out pull bar and the swirler that links to each other with pull bar backward, only use can be finished clean and maintenance in 1～2 minute, need not spray gun integral body is carried out disassembly, cleaning, this point also is than the advanced part of other same device.
