Abstract
The utility model discloses a bubbler used for melting glass, which belongs to the field of tank furnace melting of glass production. The bubbler comprises a porous gas pipeline and a cooling pipeline for protecting the gas pipeline. Cooling can lead the bubbler to be located at any position in depth direction of molten glass, and the position can be adjusted according to different produced glass; the multi holes can reduce the cross section of a single air-pipe outlet of a bubbling port (7), and are combined with a single-way valve (or a stop valve) and a pressure-regulating valve of a gas-supplying pipeline at upper stream of a gas inlet (4) so as to prevent molten glass from flowing backwards and controlling bubble frequency and bubble diameter.
Description
Technical field
The utility model is a kind of porous bubbler with type of cooling, belongs to glass production tank furnace fusing field.
Background technology
Cell furnace bubbling technology is a kind of pressure fusing new technology that last century, the fifties occurred, and the development of process over half a century and constantly perfect has become one of technical measures of the indispensable pressure fusing of modern cell furnace.
In cell furnace inside, it is the tank furnace fusing and the ultimate principle of homogenizing that the flame radiation heat is passed to mobile in melting pool of admixtion and glass metal and glass metal.All pressure fusing and the technical measures that improve the glass metal quality are all in order to obtain maximum heat, to improve flowing and making the thermal convection of glass metal more reasonable and stablize and carry out of temperature of glass liquid, chilled glass liquid with admixtion.
Tank furnace bubbling technology, be to adopt one or more groups bubbler, blast gas near the bottom of the tank furnace the focus and emerge bubble, along with the rising of bubble, glass metal on every side upwards flows and forms mechanical cycles stream, and the thermal convection system of glass metal is strengthened, increased the heat absorption capacity of Watch glass liquid, promoted the heat transfer of inner each interlayer of glass metal simultaneously, the bulk temperature of glass metal is improved, the glass metal melting quality obtains basic assurance.
Bubbler is normally combined by metal, alloy or ceramic pipe and the gas circuit web member of high temperature resistant, anti-thermal shock, the water eroding and flooding of anti-the glass metal, and glass metal is inserted in its upper end, the lower end links to each other with airing system by web member.
The control methods that blast glass metal according to gas are divided into two kinds of continous way (or claiming natural style) and intermittent pulse types (or claiming accurate formula).Continous way is the gas that will the purify adjusting through excess pressure, flow, continuously sends into glass metal by the tank bottom bubbling device; And intermittent pulse type is regularly sent into glass metal by bubbler after to be the gas that will purify regulate through voltage stabilizing under program control state.
In actual applications, exist following problem to restrict the development of bubbling technology, especially the application on large tank furnace used: the one, bubbler far is shorter than the kiln age of tank furnace work-ing life.Bubbling pipe is stopped up by glass metal chemical erosion and physical abrasion or pneumatic outlet at high temperature, is difficult to change maybe can not change, and one in one group of bubbler problem occurs and causes system to scrap; The secondth, after the glass metal convection current was strengthened around the bubbling pipe, temperature of glass liquid improved at the bottom of the kiln, to refractory materials chemical erosion and physical abrasion aggravation at the bottom of the kiln, did not have the bubbler of refrigerative fixed position to cause the pond bottom structure to be damaged in advance; The 3rd is the glass of production different varieties, and the bubbling position should be adjusted reaching best effect on the depth of metal direction, and existing bubbling device is difficult to adjust and maybe can not adjusts.
Summary of the invention
The utility model molten glass is with the bubbler purpose: 1. bubbler can use the optional position in depth of metal; 2. the work-ing life of the refractory materials that prolongs bubbler and be attached thereto, and the requirement of reduction bubbler material; 3. realize the adjusting of bubble bubble diameter frequently, and have anti-blocking effect.
The utility model molten glass with the technical characterictic of bubbler is: be made up of bubbling porous gas pipeline of using and the cooling line that is used for the shielding gas pipeline; The porous gas pipeline is made up of tracheae (6) and end cap (8), and end cap (8) has bubbling mouth (7) with tracheae (6) junction; Bubbling mouth (7) is communicated with tracheae (6) by 2 above circular holes, passes end cap (8) and bloats gas; Tracheae (6) lower end is by inlet mouth (4) air feed; Cooling line is made up of outer tube (1), interior pipe (2), water inlet pipe (3) and rising pipe (5); End cap (8) is connected with outer tube (1), and tracheae (6) is connected with interior pipe (2); This bubbler can use the optional position in depth of metal.
Bubbling mouth (7) Circularhole diameter is 0.5-2.0mm; Cooling line can make water, air as heat-eliminating medium.
Inlet mouth (4) is connected with supply air line, and check valve or stopping valve are installed on the supply air line in distance inlet mouth (4) 3m, and realization bubbling frequency is regulated automatically.
Employing has cooling line bubbler structure following advantage is arranged: one is to use mode such as artificial or automatic to regulate the bubbler upper end becomes feasiblely in the position of depth of metal direction, make things convenient for the glass of different varieties to carry out the technology adjustment; The 2nd, the artificial replacing of bubbler can realize, has increased system reliability, has solved and tank furnace kiln unmatched problem in age; The 3rd, form protection to refractory materials at the bottom of the pond, increased the security of using bubbler, can not impact age kiln; The 4th, the harshness of traditional bubbler gas piping material requires just to have lowered, and can use common heat-resistance stainless steel manufacturing, and the cost of bubbler decreases.
Under the situation that significantly reduces the single hole size, the porous of gas piping has guaranteed the gas passage sectional area.Reduce pore size and strengthened the resistance that glass metal pours in down a chimney, and cooperate the use of automatic check valve or stopping valve, realize the intermittently anti-blocking effect of bubbling mode.
