Abstract
The utility model discloses a hollow glass micro-balloon burner. A feed pipe (3), a gas pipe (4) and a combustion-supporting gas pipe (6) which are sequentially and coaxially sleeved form a burner nozzle; one end of the combustion-supporting gas pipe is connected with a burning pipe (5); and the side lower parts of the gas pipe (4) and the combustion-supporting pipe (6) are respectively provided with a gas inlet (2) and a combustion-supporting air inlet (1). The utility model has the advantages that because the glass micro-balloons are in the same flow direction as the burning gas flows, glass micro-balloon particles are molten in the burning flame and then only flows vertically upwards under the action of a terminal draft fan; therefore, the molten glass micro-balloons are avoided from colliding a furnace wall or other devices, so that the generation ratio of glass micro-balloons is improved and the color and the roundness are greatly improved. The burner has simple structure, can use various low-price coal gases, and have stable combustion and little equipment investment.
Description
Technical field:
The utility model relates to a kind of device that hollow glass micropearl is produced that is used for, and is specifically related to a kind of burner that hollow glass micropearl is produced that is used for.
Background technology:
Hollow glass micropearl is the small hollow glass ball of a kind of size, have light weight, thermal insulation, sound insulation, high-low temperature resistant, electrical insulating property and Heat stability is good, advantage such as corrosion-resistant, not only can be used as the widespread use in plastics industry of novel packing material, can also be used as the light-weight additive of light weight cement, drilling fluid, to solve the difficult problem of deep layer drilling well.Present hollow glass micropearl burner, a kind of glass microballon apparatus for continously production is disclosed as Chinese invention patent CN1396130A, its microballon firing furnace has injecting combustor, glass particle enters roasting the flame from the direction perpendicular to burner flame, because the influence of air-flow, the activity of fused glass microballon can't limit, and collides pyritous furnace wall or other device easily, thereby being difficult to produce short grained glass microballon, bead yield rate is very low.US3361549 has also introduced a kind of device that glass microballon is used of making, and this device mainly contains body of heater, burner and funnel-form microballon collector and constitutes.The top of body of heater and sidewall separating atmospheric, burner places the bottom of furnace body center, nozzle upwards, combustion gases and glass particle enter burner by two mouths respectively, combustion gases serve as carrier and carry glass particle and enter the combustion chamber and burn, the glass particle melted by heating, along with air-flow upwards is cooled to pearl gradually, air-flow is forced to diffusion all around at furnace roof, then downward along the furnace wall, form a buffer layer between hot gas flow and furnace wall, downward air-flow carries microballon and falls into funnel-form microballon collector through the body of heater lower end, and waste gas directly enters atmosphere by the funnel top.Because burner nozzle makes progress, microballon moves upward earlier under the jet power effect, after be subjected to influence of gravity and convection action to turn to down motion, the microballon that rises and descend collides in high temperature and makes the microballon distortion, cause decrease in yield, temperature head is less in the body of heater simultaneously, the microballon speed of cooling is slower, easily forming molten mass on burner nozzle piles up, in addition, glass particle is clipped in and supplies to the combustion chamber in the combustion gases, makes between flame and the glass particle well to contact, and easily forms the tendency of glass particle caking.
The utility model content:
The purpose of this utility model is exactly at above-mentioned defective, provides a kind of simple in structure, and flameholding can be used for producing a kind of burner of high bead yield rate hollow glass micropearl.
For achieving the above object, the utility model adopts following technical scheme: a kind of hollow glass micropearl burner, it is characterized in that, the feed-pipe that it is fitted together by concentric locking collar successively, gas line and combustion-supporting tracheae are formed burner noz(zle), combustion-supporting tracheae an end connect a concentric incendiary pencil, quirk in the outlet of feed-pipe, gas line and combustion-supporting tracheae and the incendiary pencil communicates, the opening for feed of feed-pipe is located at the burner bottom, and the side lower part of gas line and combustion-supporting tracheae is provided with a fuel gas inlet and combustion air inlet respectively.
Described feed-pipe and feed-pipe outlet are positioned at the burner noz(zle) center, a little higher than gas line outlet in its position and the outlet of combustion-supporting tracheae.One group of spinning disk that tilts is set uniformly, so that the combustion air eddy flow enters quirk and combustion gas mixing in the described combustion-supporting tracheae.In gas line exit and feed-pipe exit an annular end cap is set, the annular end cap upper edge is circumferentially uniform to be provided with one group of fire jetting hole.
Essence of the present utility model is, opening for feed is located at the burner bottom, from bottom centre's charging, enter quirk and the state of combustion air-flow converges by feeding-passage, combustion gas is sprayed by nozzle by blast tube, and combustion air flows to combustion gas mixing and burning into furnace chamber and ejection by air passageways at spinning disk effect backspin.Described glass particle outlet is positioned at the gas jet center, a little higher than gas outlet in its position and combustion air outlet, and glass particle enters roasting the flame from the direction that is equilibrated at burner flame.Described combustion gas is concentric outflow with combustion air, but air is the eddy flow state, and it is fierce to stir, favourable its thorough mixing.Described combustion gas is burnt while mixing at the ejiction opening place with combustion air, flame stabilization, and be difficult for tempering and take off fire, regulation range is bigger, for microballon provides a stable roasting space.
Advantage of the present utility model is: simple in structure, be suitable for various low price coal gas, and flameholding, facility investment is few.The utility model has been controlled the temperature of combustion flame easily by the pressure and the flow of control burning gas and combustion air, adapts to the formation of various particle diameter glass microballons.Because the flow direction of glass microballon and the flow direction of combustion gas flowing are consistent, the glass microballon particle is in burned flame after the fusion endways under the induced draft fan effect, can only flow vertically upward and cooling rapidly, thereby avoid the collision of fused glass microballon and furnace wall or other devices, thereby having improved the bead yield rate of glass microballon, color and luster and rounding property also improve greatly.
