Abstract
A unit kiln of smelting neutral glass is composed of kiln pool, heat exchanger, heater and auxiliary heater and flue, and features that a metal heater and flue is on the front of the kiln pool, the electrically auxiliary heater is on side wall of kiln spool and its kiln threshold and pure-oxygen bubbling unit is on the bottom of kiln pool. Its advantages are high temp stability, flexible regulation of heating point, simple structure, low cost and long service life.
Description
The invention belongs to glass furnace, particularly relate to the kiln that melts neutral glass.
Neutral glass is because alkali content is low, and the coefficient of expansion is low, clarification fusing difficulty, and especially bubble is difficult for getting rid of in the glass metal, and at U.S. Pat P3, what adopt in 420,653 is the cellular-type tank furnace, by the partition wall with several dog-holes kiln is divided into former and later two parts.Admixtion forwardly by after the bottom electrode fusing, enters the latter half clarification through the partition wall dog-hole.The glass metal surface is by flame heating herein, and electric boosting is carried out by the number counter electrode in the bottom, and glass metal is well clarified.Since the separated into two parts tank furnace, complex structure, partition wall water cooling simultaneously, thermo-efficiency is low, can be etched after the partition wall long-time running and collapse, and shortens the tank furnace life-span.
The purpose of this invention is to provide a kind of unit kiln that melts neutral glass, it is at the defective of prior art and having of designing do not commutate, kiln temperature is stable, focus kiln flexibly easy to adjust.
The objective of the invention is to realize by the following technical solutions: integrated application pure oxygen bubbling, pool wall electricity fusing-aid and weir technology, the reasonable combination on the line position of going forward side by side.This unit kiln along electrode, pure oxygen bubbling and weir are set on the length direction of kiln melting pool, in locational reasonable arrangement, makes neutral glass fusing and clarification reach best effect according to neutral glass fusing and clarifying needs.
The present invention adopts sidepiece combustion heat-exchange formula, and burner is distributed on the length direction of unit kiln both sides, and combustion exhaust leaves tank furnace by back wall exhaust outlet, enters metallic recuperator by the refractory materials flue, by thermal conduction waste gas combustion air is carried out preheating at this.Taking Sweet natural gas or heavy oil is the fuel of burner, air after preheating along glass metal in the both sides burner heating bath that is provided with on the unit kiln length direction, one-sided charging opening, set gradually pure oxygen bubbling and weir along the pond length direction, simultaneously along on the length direction sidewall block of pond or heating electrode is set at the bottom of the pond.Electricity fusing-aid is divided into three districts, can regulate electrical heating power separately according to arts demand.Weir can be stablized glass metal focus convection current in the stove, and the glass flows that stops that the bottom is contaminated or contain impurity is gone into dog-hole.The structure of weir brick can adopt individual layer or bilayer.
The present invention includes kiln, metallic recuperator, burning heating and electric auxiliary heating device, below the sidewall metal level of the pond of melting pool,, be provided with weir and pure oxygen bubbling device in the bottom, pond or/and the bottom, pond is equipped with electric auxiliary heating device.Electrically heated can be adopted three-phase or single-phase heating, and its system is made up of electrode, electrode water jacket, seal, transformer and setter etc.
Unit kiln of the present invention is used electrically heated, pure oxygen bubbling and weir at first melts glass metal, and clarification is forced in the back.It has do not commutate, kiln temperature is stable, focus advantage such as flexibly easy to adjust, it can omit horse shoe flame or cross flame regenerator, tank furnace simple for structure, cost reduces simultaneously, and the type of furnace life-span is long, and is easy to operate.Promptly be applicable to neutral glass, also be applicable to and found and produce borosilicate glass and glass fibre.Tank furnace is simple for structure, and cost reduces simultaneously, can solve the problem that neutral pharmaceutical glass clarification is difficult, fusing is difficult fully, and the inner quality of producing glass is to meet the neutral glass that international similar level requires.
Below in conjunction with accompanying drawing and with it is that the invention will be further described for embodiment:
Fig. 1 is the vertical section structure synoptic diagram of the embodiment of the invention;
Fig. 2 is the A-A view of Fig. 1;
Among the figure: the 1st, metallic recuperator, the 2nd, flue, the 3rd, melting pool, the 4th, electricity fusing-aid one district, the 5th, pure oxygen bubbling device, the 6th, weir, the 7th, dog-hole, the 8th, electricity fusing-aid two districts, the 9th, electricity fusing-aid three districts, the 10th, charging opening, the 11st, flame burner nozzle brick, the 12nd, bubbling brick, the 13rd, electricity fusing-aid one region electrode brick, the 14th, electricity fusing-aid two region electrode bricks, the 15th, electricity fusing-aid three region electrode bricks, the 16th, electrode.
In Fig. 1, metallic recuperator 1 and flue 2 are positioned at melting pool 3 front portions, the sidewall of melting pool 3 from preceding to after be provided with three groups of electrodes 16 successively, promptly on each electrode block 13,14 and 15, molybdenum electrode 16 is housed respectively; Electrode block 13 and 14 bubbling brick 12 is arranged; Weir 6 is located between electrode block 14 and 15, and dog-hole 7 is in electrode block 15 rear portions.
As can be seen, because three groups of electrodes 16 make melting pool 3 be divided into three zones, promptly form electricity fusing-aid one district 4 in electrode block 13 front and back in Fig. 2, it is positioned at the admixtion overlay area, can help to melt admixtion; Form electricity fusing-aid two districts 8 in electrode block 14 front and back, it is positioned at the hot spot region of this kiln to strengthen the convection current of furnace charge; Form electricity fusing-aid three districts 9 in electrode block 15 front and back, it promptly at weir 6 katabatic drainage places, is convenient to get rid of residual bubble from glass metal between weir 6 and dog-hole 7.In each heating zone, respectively be provided with 4-8 and prop up molybdenum electrode 16.
Bubbling device 5 is positioned at the bottom of the pond at melting pool 3 middle parts, it is to comprise the bubbling brick 12 at the bottom of the pond and be installed in bubbling pipe in the pre-opened hole on the brick 12, along adopting single or double bubbling device 5 on kiln melting pool 3 widths, can its quantity be set according to the width difference of melting pool 3; Usually the spacing of bubbling brick 12 is between 300-600mm.Bubble oxygen device 5 can strengthen the convection current of melting area and settling section.Pure oxygen can reduce undissolved gas bubble in the glass metal as the source of the gas of bubbling, strengthen the eliminating speed of bubble, pure oxygen is by the bubbling dish, linked by copper tube and insulation tube and bubbling pipe 5, bubbling pipe 5 can be provided with flow control valve and warning device, possesses the standby oxygen supply of automatic emergency simultaneously.
