Description

The production method of glass sphere and equipment
The present invention relates to a kind of method of producing glass sphere, in this method, raw material is subjected to the effect of flame in a combustion chamber, so that this raw material is heated and makes said glass sphere, and is taken out from said combustion chamber.The invention still further relates to the equipment of making glass sphere, comprising a combustion chamber, fuel and oxidizer are provided for said combustion chamber so that produce the equipment of flame and add raw material in the flame so that heat and change into glass sphere, and the equipment that the ball of making is taken out from the combustion chamber.
The whole bag of tricks and the equipment of production that is used for the production of solid glass ball and multicellular glass ball is known.
For example, in the manufacturing processed of solid ball, the known glass particle raw material that will deliver fragmentation in the air-flow of people is given the combustion chamber, and in the combustion chamber, glass particle flows by flame heating, thereby makes broken glass become spherolite.Similarly, for the manufacturing of foam ball, people are known to be to provide a kind of coccoid raw material to the combustion chamber.In the combustion chamber, because the effect of flame, these beads are heated, and change into the multicellular glass ball.A kind of like this raw material is normally by spraying-dry a kind of solution (for example a kind of based on the silicate hydrate sodium solution, but also contain the solution of a kind of foaming agent (for example urea)) and make.
The mode of heating raw to the quality of shaping ball and output cause close important, especially when those balls will be made the multicellular glass ball.Simultaneously, the economy to production process also is very important.Rapid heating to form spherolite and (or) vitrifying of raw material is favourable, and this needs the good thermo-contact of flame and stock yard.In order to obtain the product of a homogeneous quality, importantly in the combustion chamber, should be processed equably by the made ball of this kind production method, reduce simultaneously between solid material bonding and (or) tendency that adheres on the sidewall of combustion chamber also is important, above-mentioned bonding and adhesion situation, may be that over-heating causes during the feedstock conversion balling-up.
An object of the present invention is to satisfy above-mentioned ask for something at least in order to help.
A kind of method of producing glass sphere that proposes according to the present invention, in this method, raw material is subjected to the effect of flame in the combustion chamber, and this raw material is heated, and makes said glass sphere, and after this, these balls are taken out from said combustion chamber.The raw material that it is characterized in that above-mentioned said supply combustion chamber is diffused in the delivery air-flow, this delivery stream is a kind of mixture, comprising giving burning fuel gas and oxygen that interior flame provides, non-flammable gas also offers the combustion chamber simultaneously, in order to keep an air-flow, this air-flow is along the flame track, and flows around flame, to form a gas ring.
By various overall characteristics provided by the invention, guarantee raw material is carried out all even processing well, to increase the output of gained high quality ball.Owing to adopted this method that raw material and gas is offered the combustion chamber, each unfashioned ball is surrounded fully by a stable flame, they are heated rapidly in the gas ring, this gas ring is passed to raw material and ball to additional kinetic energy, transfer out the combustion chamber so that the ball that processes collected, and ball is remained under the state of abundant diffusion, thereby avoided ball bonding or adhered on the side wall of combustion chamber.A prior advantage of the method applied in the present invention is, people find, are effectively making in the ball process, and side wall of combustion chamber is than cold under other situation, and help like this improving hot worked economy, and help to prolong the useful working life of combustion chamber.
In preferred forms of the present invention, said gas ring is formed by the air that offers the combustion chamber, and this all is favourable to improving economy and accessibility, and because the result that nitrogen exists provides a favourable ballast.This gas ring can provide one deck screen efficiently, with stop glass or can vitrified material impacts side wall of combustion chamber.Equally, this airborne additional oxygen that is provided has promoted the perfect combustion of fuel gas, has further improved the economy of fuel.Owing to similar reason, the oxygen that replenishes in the preferably said non-flammable gas can guarantee that the oxygen in the combustion chamber surpasses and keep the required amount of oxygen of said fuel perfect combustion.
If the air of providing preferably for said gas ring is three times for the said fuel required air of perfect combustion at least, this will make advantage of the present invention more remarkable.
Except that the bonding of ball and they adhere to the problem of sidewall of combustion chamber, if over-heating some further problem also can occur, especially with regard to foam ball.If foam ball is heated excessively, the bubble wall is softened such degree and produces the trend of damaging to cause them, thereby causes the qualification rate of good moulding ball to reduce.
Therefore, wish the flame temperature of heat balls in the restriction combustion chamber.People know that regulating flame temperature has three kinds of methods, and each method is used in the sort of production method involved in the present invention, all can show the disadvantage of oneself.At first, flame temperature can be regulated by suitable selection fuel.In fact, should be local piped gas supply because consideration economically requires fuel used usually, i.e. town gas, or more common natural gas.Certainly, other fuel also can use, but this certainly will disproportionately increase production cost.When the fuel provided was provided, flame temperature can be regulated by too much fuel or too much air are provided to flame.If too much fuel is provided, because be used for the oxygen deficiency of perfect combustion, the flame that is produced will reduce greatly, thereby when production method of the present invention is implemented under these conditions, the ball of the being produced blackening that is bound to, this has just caused the serious limitation of they use aspects.Otherwise in order to limit flame temperature, if too much air is provided, flame will can not keep stable, thereby cause the inhomogeneous of ball processing.Use too much air, be disadvantageous to the perfect combustion of fuel, and can reduce flame transmission speed greatly.When a kind of meticulous substantially material that is divided into during at the flame internal diffusion, the repressed trend of flame will increase, and it must be in the enforcement of a kind of production method of the above-mentioned type certainly.In brief, previously known production method is not satisfied.
Adopt some preferred forms of the present invention, no matter the size of fuel used heat release in gas region, these problems can both be resolved.
In preferred forms more of the present invention, the thermal value that said fuel gas has is at least 6000 kilocalories/Where 3For example, can use and have about 8000 kilocalories/Where 3The Sweet natural gas of thermal value.People find, use a kind of like this delivery air-flow (it is surrounded by a gas ring, and this gas ring provides too much supplemental oxygen to the combustion chamber) in the fuel of oxygen mix, particularly when offering the combustion chamber, use a large amount of too much air the sort of fuel, can produce advantageous effect aspect reduction flame temperature and the prolongation flame, thereby improved the output good, the uniform ball of processing that is shaped, and do not had the danger of restraining flame or making the ball blackening.In this embodiment, best said delivery air-flow is a kind of very easily incendiary mixture, and this has further reduced to restrain any danger of flame.Especially advantageously, the ratio that comprises oxygen in the delivery air-flow accounts for 1/4~3/4 of the interior perfect combustion aequum of said fuel chambers, and preferable ratio is to account for 1/3~2/3 of said fuel perfect combustion aequum.The oxygen that comprises such ratio in the delivery air-flow has promoted the stable of flame and has helped fuel combustion.For example, the required amount of oxygen of Sweet natural gas (can think methane) perfect combustion is slightly less than the twice of volume of himself oxygen or 10 times of himself volume of air: the suitable proportion that the delivery air-flow that is provided is provided is the air of the Sweet natural gas of a volume than 5 parts of volumes, is half of perfect combustion aequum.
In other preferred forms of the present invention, the thermal value that said fuel gas has is no more than 5000 kilocalories/Where 3For example can use town gas.When being used for production method of the present invention, this obtains extraordinary result equally.
When using a kind of gas with such lower calorific value, preferably manage to increase the high-temperature residence time of unshaped ball, therefore it is favourable using embodiments of the invention, in the present embodiment, the polynary air-flow that contains fuel gas and oxygen offers the combustion chamber at least along length of flame direction in an annular zone band, and several strands of air-flows are concentrated mutually, and intersect with said flame.Advantageously in such annular zone band, have three strands of air-flows of concentrating like this at least, so that promote the homogeneity of processing.Preferably should have 2 said annular zone bands at least, in this annular zone band, the air-flow of concentrating offers the combustion chamber so that further increase the time that high temperature continues, perhaps advantageously, at least one such annular zone band is set, and the spacing of it and flame root is 1/3 of combustion chamber length at least.
The fuel that preferably this concentrated air-flow contains and the ratio of oxygen are enough to satisfy the perfect combustion of the sort of fuel.This has promoted flame quite firmly to assemble, and when using a kind of like this gas of lower calorific value with box lunch, obtains the good required temperature of shaping ball, and the convergence of flame helps to concentrate heat in the annular zone band of this focused airflow.
Supply with identical substantially gaseous mixture with said delivery air-flow especially preferably for said convergence air-flow.
No matter what fuel gas is used in the enforcement of production method of the present invention,, it would be desirable that the delivery air-flow should comprise the raw material in the direct mixture that fully is diffused in a kind of inflammable and combustion-supporting gas in order to promote the homogeneity of raw material processing.For this reason, the first kind of composition that preferably has a delivery air-flow of transported raw material advances along a passage that leads to the combustion chamber.Second gaseous constituent of this delivery air-flow is compelled to laterally compress into that passage by at least one hole on the passage perisporium, and the mixing delivery air-flow that wherein has the raw material that is transferred was subjected to further promoting direct blended reactive force there before arriving the combustion chamber.
After leaving flame, the ball of advantageously making still is diffused among the air-flow before being collected, and passes through a cooling zone with gas stream.This just makes the ball of making after leaving flame, unlikely bonding.
The present invention also provides the equipment of making glass sphere, it comprises a combustion chamber, give said combustion chamber provide fuel and oxidizer to produce flame equipment and add raw material in the flame so that heat and change into glass sphere, and the equipment that the ball of making is taken out from the combustion chamber.According to the present invention, wherein said equipment comprises and is used for supplying raw materials to the combustion chamber that (this raw material is to be spread in a carrier gases that comprises said fuel and oxidizer, and be transferred with it) the burning boiler tube, round this roasting kiln pipeline equipment with keep non-flammable gas stream by this pipe-line equipment, and the direction identical with the material stream that sprays from the roasting kiln aperture enters the combustion chamber, so that form the equipment of a gas ring round described material stream.
A kind of like this equipment is particularly suitable for use in the enforcement of method of the present invention.When using by this method, the production method that these equipment adopt just embodies its superiority, and particularly these equipment have long useful working life and reduced the advantage of maintenance.
In order to keep an airflow to flow through above-mentioned pipe-line equipment, blower equipment is set preferably.Air is a kind of dog-cheap gas resource that is used to form above-mentioned gas ring, and has to fuel chambers and provide additional oxygen to help the advantage that production process is carried out.
Advantageously at least one the annular zone band on the length direction of combustion chamber, a plurality of pilot jets are set, comprise that with guiding the multiply air-flow of fuel gas and oxygen enters the combustion chamber and assembles mutually, and with crossing from the material stream of burning boiler tube ejection.Adopt these pilot jets, play a part a kind of favourable increasing the heat that produces in the combustion chamber.This has special value when adopting the combustion gases (as town gas) of quite low thermal value.
