Abstract

The utility model discloses a high-pressure swirl flaming brick, which solves the problems of the existing inflamer that the mixing of the fuel gas entering the furnace chamber and the combustion-supporting air is not even, and the combustion is incomplete. The characteristics are as follows: a flaming brick body (8) is a cylinder, and the surface of the flaming brick body is provided with fixed ribs (1), an axial center is provided with a flaming hole, and the flaming hole comprises circular holes (2) arranged at two end parts of the flaming brick body (8) and a trumpet hole (5), a small circular hole (4) arranged at the middle part and a shrinkage hole (3); the flaming brick body (8) is fixed in a funnel-shaped circular hole arranged in a heavy burner brick through the fixed ribs (1), and forms an interval-type main combustion-supporting air annular inlet (7) with the funnel-shaped circular hole, meanwhile, combustion-supporting auxiliary air holes (6) are evenly arranged at the periphery of an inner flaming hole of the flaming brick body (8). The high-pressure swirl flaming brick has functions of guiding, stream-splitting, stirring, and mixing for the fuel gas and combustion-supporting air, therefore, the mixing is even, the consumption is complete and stable; the energy source is saved, the operating difficulties of adjusting air-fuel ratio, controlling flame during combustion process are reduced.

Description

High pressure cyclone flame brick

One, technical field

Metallurgical, chemical industry kiln Thermal Equipment that the utility model belongs to relates in particular to make temperature in the stove and atmosphere is stable, efficiency of combustion is high high-efficiency and energy-saving type burner accessory high pressure cyclone flame brick.

Two, background technology

At present, for adaptation is built a resource-conserving society, the kiln industry adopts heat accumulating burner capable more and more, usually all be that combustion gas and combustion air mixing are directly entered the kiln Indoor Combustion through behind the burner block, though than conventional burners bigger progress has been arranged, but still has existed combustion gas to mix problems such as inhomogeneous, that burning is insufficient, the thermal efficiency is low with combustion air.

Three, summary of the invention

The purpose of this utility model is for furnace equipment manufacturing enterprise provides a kind of simple in structure, can be to combustion gas and combustion air guiding, shunting, stir, have mix, the burner accessory high pressure cyclone flame brick of advantage such as sufficient combustion.

Technical solution adopted in the utility model is: high pressure cyclone flame brick is made up of flame brick body and heavy burner block.Evenly be provided with fixedly muscle on the surface of cylindrical flame brick body, and be provided with fire jetting hole at shaft core position, this fire jetting hole by the circular hole and the bellmouth orifice that are arranged at flame brick body both ends, be arranged at the middle part small sircle hole and shrinkage hole constitute, the circular hole of end links to each other with small sircle hole by shrinkage hole, and small sircle hole links to each other with the bellmouth orifice of the other end.And in flame brick body, evenly be provided with combustion-supporting auxiliary wind hole around the fire jetting hole, and this hole becomes 15 ° of angles with central axis, and its outlet communicates with the bellmouth orifice of fire jetting hole end.Flame brick body is fixed in the infundibulate circular hole that is provided with in the heavy burner block by fixing muscle, and with its formation combustion air main-inlet.

The beneficial effects of the utility model are, novel structure, easy to assembly, owing to adopt fixedly muscle structure of contraction, bellmouth orifice and inclination, combustion gas and combustion air are led, shunt, stirred, increased gas flow rate, making combustion air form eddy flow makes itself and combustion gas mixing even, sufficient combustion had both been saved the energy, had also reduced the operation easier of regulating wind combustion ratio, control flame in the combustion process, improve energy use efficiency greatly, had environmental protection, premium properties such as energy-conservation.

Four, description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model flame brick structure schematic diagram;

Fig. 2 is the utility model A-A cross-sectional view;

Fig. 3 is the utility model B-B cross-sectional view.

Among the figure: 1 is the fixedly muscle that tilts, and 2 is circular hole, and 3 is shrinkage hole, and 4 is small sircle hole, and 5 is bellmouth orifice, and 6 is combustion-supporting auxiliary wind hole, and 7 is the combustion air main-inlet, and 8 is flame brick body.

Five, the specific embodiment

As shown in the figure, to produce the matching used high-speed rotational formula of a magnesium reducing furnace heat-storage type burner flame brick is example, flame brick body 8 is a cylinder, employing has half corundum material of good hear resistance and heat endurance and makes, its diameter and thickness are 160 millimeter, and fixedly muscle 1 of inclination that four thickness and width be 40 millimeter is set evenly on its surface, and being provided with fire jetting hole at shaft core position. this fire jetting hole is the bellmouth orifice 5 that 65 millimeters circular hole 2 and big small-bore are respectively 70 millimeters and 25 millimeters by the aperture that is arranged at flame brick body 8 both ends, the aperture that is arranged at the middle part is 25 millimeters small sircle hole 4 and big small-bore shrinkage hole 3 formations of 60 millimeters and 25 millimeters respectively, the circular hole 2 of end links to each other with small sircle hole 4 by shrinkage hole 3, small sircle hole 4 links to each other with the bellmouth orifice 5 of the other end, the necessary strict guarantee in four holes is concentric, excessive burning difficulty that causes of combustion gas resistance or flame brick are washed away and are damaged when preventing to burn. and fire jetting hole is provided with fixing muscle 1 orientation all around evenly to be provided with four apertures is 20 millimeters combustion-supporting auxiliary wind hole 6 flame brick body 8 in simultaneously, this hole becomes 15 ° of angles with axis, its outlet communicates with the bellmouth orifice 5 of fire jetting hole end. and heavy burner block outer surface is a square, its shaft core position is provided with the fixedly circular hole and the infundibulate eyelet of flame brick body 8. when then forming compartment annulus combustion air main-inlet 7. enforcement the utility model of one 40 millimeters between flame brick body 8 and the heavy burner block, with high pressure cyclone flame brick bury be loaded on burner need be set kiln within the walls, diameter with burner is the circular hole 2 interior location of 60 millimeters gas pipeline insertion flame brick then, gas pipeline is just in time closely cooperated with the shrinkage hole 3 of flame brick, and guarantee with one heart. during burning, combustion gas is subjected to resistance by shrinkage hole 3 to small sircle hole 4, treat to obtain higher flow velocity and inertia after it enters bellmouth orifice 5, after fully mixing, the combustion air that the combustion-supporting auxiliary wind hole 6 that is provided with around eddy flow shape wind that enters with combustion air main-inlet 7 and the fire jetting hole enters enters the burner hearth burning. and bent in the mixing and the stirring that have strengthened between combustion gas and the combustion air, combustion gas is fully burned, both reduced energy consumption, combustion atmosphere in the burner hearth is improved, and product quality also is improved significantly in the stove thereby make.
