Abstract
The invention discloses an energy-saving annealing furnace for hydroxyl removal of a quartz tube, which comprises a furnace body and a furnace leg. A hearth and a tungsten rod are arranged in the furnace body. The energy-saving annealing furnace is characterized in that the furnace body is provided with inner and outer insulating walls, an aluminum silicate fiber insulating material is filled between the inner and outer insulating walls, and the inner and outer insulating walls consist of light refractory bricks. The energy-saving annealing furnace for the hydroxyl removal of the quartz tube has good integral insulating performance and saves electrical energy by arranging a reasonable insulating structure and materials, and the electricity saving quantity can reach 30 percent through use calculation, namely saving energy of about 40kV every hour.
Description
Technical field
The present invention relates to a kind of hydroxyl removal of quartz tube equipment, particularly a kind of energy-saving annealing furnace for hydroxyl removal of quartz tube.
Background technology
All contain a certain amount of hydroxyl (OH) in the quartz glass tube, the hydroxy radical content height the direct work-ing life that influences silica tube, therefore need carry out deshydroxy annealing.The deshydroxy annealing furnace is to remove or to reduce one of specific equipment of silica tube hydroxyl by high temperature.
There is following defective in domestic common hydroxyl removal of quartz tube annealing furnace at present:
1, the heat-insulation and heat-preservation wall is the individual layer light fire brick, and fill insulant material is a Sickle stone, so furnace binding is unreasonable, and heat-insulating property is poor, deshydroxy energy consumption height;
2, the general foreign minister 3200mm of body of heater, outer wide 1700mm, about heating element tungsten bar diameter 25mm, two groups totally 18, installed capacity 40KVA, furnace volume is little, and is can deshydroxy silica tube 1400mm long.The body of heater dimension scale is unreasonable, not only because of volume little can't deshydroxy the lengthening silica tube, and irrational body of heater dimension scale has also improved the deshydroxy energy consumption.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, provides that a kind of structure is more reasonable, good heat insulating, energy-saving annealing furnace for hydroxyl removal of quartz tube that the deshydroxy energy consumption is low.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of energy-saving annealing furnace for hydroxyl removal of quartz tube, comprise body of heater and stove leg, be provided with burner hearth and tungsten bar in the body of heater, be characterized in: described body of heater is provided with inside and outside double-layer heat insulation wall, fill between inside and outside double-layer heat insulation wall and be provided with the aluminum silicate fiber lagging material, inside and outside double-layer heat insulation wall is made of light fire brick.
Technical problem to be solved by this invention can also further realize by following technical scheme.Above-described energy-saving annealing furnace for hydroxyl removal of quartz tube is characterized in: described body of heater foreign minister is 4330mm, outer wide 2600mm, high 1700mm; The long 3900mm of burner hearth, wide 815mm, high 950mm; The diameter 25mm of described tungsten bar is provided with 42 altogether, divides 2 groups evenly to be provided with.
Compared with prior art, the technique effect of energy-saving annealing furnace for hydroxyl removal of quartz tube of the present invention and the energy-saving annealing furnace for hydroxyl removal of quartz tube of the present invention through further designing is as follows:
1, energy-saving annealing furnace for hydroxyl removal of quartz tube of the present invention makes its integral heat insulation performance good by rational insulation construction and material are set, saves energy, and through using measuring and calculating, amount of electricity saving can reach 30%, about promptly per hour energy-conservation 40KV.h.
2, the body of heater of energy-saving annealing furnace for hydroxyl removal of quartz tube of the present invention is big, and particularly furnace volume is big; The Proper Design ratio is reasonable, by reasonable radical being set and uniform tungsten bar being set, can effectively cut down the consumption of energy under the uniform prerequisite of temperature in guaranteeing stove.
3, the adaptable deshydroxy length of energy-saving annealing furnace for hydroxyl removal of quartz tube of the present invention is long, and the longest 3800mm length of taking off has solved the difficult problem that present domestic deshydroxy stove can not take off the lengthening silica tube.
Embodiment
Below further describe concrete technical scheme of the present invention,, and do not constitute restriction its right so that those skilled in the art understands the present invention further.
Embodiment 1.With reference to Fig. 1.A kind of energy-saving annealing furnace for hydroxyl removal of quartz tube, comprise body of heater and stove leg, be provided with burner hearth and tungsten bar in the body of heater, described body of heater is provided with inside and outside double-layer heat insulation wall, fill between inside and outside double-layer heat insulation wall and be provided with the aluminum silicate fiber lagging material, inside and outside double-layer heat insulation wall is made of light fire brick.
Embodiment 2.In the embodiment 1 described energy-saving annealing furnace for hydroxyl removal of quartz tube: described body of heater foreign minister is 4330mm, outer wide 2600mm, high 1700mm; The long 3900mm of burner hearth, wide 815mm, high 950mm; The diameter 25mm of described tungsten bar is provided with 42 altogether, divides 2 groups evenly to be provided with.
Detect through on probation, the body of heater of the energy-saving annealing furnace for hydroxyl removal of quartz tube described in the present embodiment, the length of burner hearth and ratio thereof are the most reasonable, by even setting 2 groups totally 42 tungsten bars can guarantee the deshydroxy effect, adapt under the prerequisite of long tube deshydroxy and effectively cut down the consumption of energy.
