The specific embodiment
As shown in Figure 1, in the preferred embodiment of premix burner of the present invention, comprise main fiery device 1 and the igniter 2 that is arranged on the fiery device of this master 1 next door, the fiery device 1 of described master comprises mixing chamber 11, air compartment 12, air inlet pipe 13, main fire-fighting mouth 14, orifice plate 15 fires.Wherein said mixing chamber 11 is a cylindrical or similar cylindrical housings, its upper and lower end opening.Described air compartment 12 is a three-way pipe, and the last end interface 121 sealing releasable connections of this three-way pipe are to the lower ending opening of described mixing chamber 11; The side direction interface of this three-way pipe is an air inlet 122, and this air inlet 122 is communicated with the outlet of blower fan by pipeline, and air is introduced described air compartment; The following end interface 123 of this three-way pipe seals releasable connection with the middle part of described air inlet pipe 13.One end of described air inlet pipe 13 is an air inlet 131, be communicated with gas pipeline, the following end interface that its other end passes described three-way pipe stretches into described air compartment 12, and the afterbody of its inserting end is provided with described main fire-fighting mouth 14, and this main fire-fighting mouth 14 is near the lower ending opening of described mixing chamber 11.So, the combustion gas introduced of the air sent into of blower fan and air inlet pipe 13 all is sent to the lower ending opening of mixing chamber 11.The air compartment structure of this three-way pipe, the main fire-fighting mouth 14 in the air compartment 12 is stretched in convenient installation, replacing.
Also can offer a plurality of fumaroles 141 on the sidewall of described main fire-fighting mouth 14, these fumaroles 141 circumferentially are distributed on the sidewall.So, be admitted to mixing chamber 11 after the air mixing of combustion gas with air compartment 12 of these fumarole 141 ejections, it is partially mixed to make that combustion gas and air just have before entering mixing chamber 11, thereby mixing is more abundant, and efficiency of combustion is higher.
The inside of described mixing chamber 11 is provided with one or more porous plate 16, a plurality of pores evenly distribute on every block of porous plate 16, make the gaseous mixture that imports from mixing chamber 11 lower ending openings pass these pores, thereby it is more abundant to make that combustion gas and air mix, efficiency of combustion is higher.The aperture difference of pore on the porous plate of different masses, the dense degree of pore also can be different on the porous plate of different masses, the radial distance difference between promptly adjacent two pores, the path difference when so gaseous mixture passes different porous plate, make that air and combustion gas mixing are more abundant, efficiency of combustion is higher.
The described orifice plate 15 that fires covers described mixing chamber 11 upper end open, and this orifice plate that fires is the thin-walled orifice plate that refractory material or metal material are made, and its upper surface covers wire netting.The sidewall of this thin-walled orifice plate is provided with hold-down ring 17, and this hold-down ring 17 is fixed on described wire netting on the thin-walled orifice plate, and can be with described fire output hole sleeve-board in the outlet of the upper end of described mixing chamber.Described wire netting also can wait fastening structure or securing member fixedly to cover thin-walled orifice plate upper surface by welding.This wire netting is mesh grid or the sticking net of pressing that resistant to elevated temperatures metallic fiber is made.When igniter 2 is lighted from the sufficient combustion gas of mixing of mixing chamber 11 ejection and air Mixture, allow generation flame at this orifice plate 15 that fires, heat energy is provided.Gaseous mixture evenly is separated into a lot of shallow bids by wire netting, the feasible flame stabilization that produces, thus reach steady flame effect.
Shown in Fig. 2,3, the described orifice plate 15 that fires can also be the waffle slab of being made by refractory material or metal material, uniform a plurality of sizes through hole 151 identical with shape on this waffle slab.This waffle slab can be inserted into shape by the crisscross button of a plurality of resistant to elevated temperatures sheet metals, and the spacing between the adjacent metal sheet is identical, thereby forms size square through hole or the rhombus through hole all identical with shape.This waffle slab also can be made integral type by mould by resistant to elevated temperatures metal or other refractory material.Described through hole 151 can also be made other shapes such as the circular polygon or irregular shape of annular, and described fire hole plate 15 can be made into the plane and also can be made into concave spherical surface or protruding sphere simultaneously, makes flame more concentrated, as shown in Figure 4.Equally, when gaseous mixture during from mixing chamber 11 ejection, this waffle slab evenly is separated into a lot of shallow bids, thereby reaches the effect of steady flame.In the present embodiment, the degree of depth of described through hole 151 is more than or equal to the twice of these through hole 151 equivalent diameters, and the spacing of described through hole 151 is less than 2.5 times of through hole 151 equivalent diameters, and surely flame effect was better, thermic load is more even this moment.So-called equivalent diameter is the diameter of a circle that equates with this through hole sectional area.The a plurality of through holes that distribute on the described orifice plate that fires also can be to vary in size or variform through hole, and the shape of these through holes can also be irregular other shape.
Shown in Fig. 4,5, the described orifice plate 15 that fires can also be curled into helical form by corrugated plating and make.When the described orifice plate that fires was corrugated plating, the lip-deep fold of this corrugated plating formed a plurality of through holes 151; This corrugated plating can be one, also can be two and curl simultaneously after overlapping.Equally, when gaseous mixture when mixing chamber sprays, evenly be separated into a lot of shallow bids by this helical ripple plate, thereby reach the effect of steady flame.Described corrugated plating also can be replaced by the intensive refractory metal plate that is provided with a plurality of projectioies in surface, and this projection can be the boss that is dispersed in metal sheet surface, also can be the raised line in the metal surface of gathering.After metallic plate curled, described projection was divided into a plurality of thin channel with the gap between the metallic plate, made to be separated into a lot of shallow bids from mixing chamber ejection gaseous mixture, reached steady flame effect.
