Description
Technical field
The present invention relates to field of glass production technology, more particularly to a kind of waste heat boiler of all-oxygen combustion glass furnace.
Background technology
Glass furnace is a kind of industry kiln that frit is melted using the fuel such as the natural gas that burns, heavy oil generation high temperature
Stove, different according to combustion-supporting material are divided into air burning glass furnace and all-oxygen combustion glass furnace again.Content of oxygen in air is about
21%, and the oxygen purity of all-oxygen combustion reaches 90%-99%.Major advantage using all-oxygen combustion mode is：All-oxygen combustion glass
The energy consumption of kiln is less than air burning glass furnace, and ignition temperature is higher, and the glass quality produced is good, and burn the waste gas for producing
Few, the content of NOx is significantly less than air burning glass furnace in waste gas, it can be seen that, pure oxygen combustion technology is that glass enterprise is realized
The important channel of energy-saving and emission-reduction improve product quality.
Call and further reduction production cost in response to national energy-saving emission reduction, China's glass furnace major part are all matched somebody with somebody
It is cased with boiler of power generation by waste heat.Using the glass furnace of pure oxygen combustion technology, its waste gas discharge temperature melts 1 ton at 1000 DEG C or so
The exhaust gas volumn about 650-800Nm that glass metal is produced3/ h, EGT is high, and flow is small, and sulphates content is higher in flue dust（Especially
It is Na2SO4）, flue dust can be in molten state at 1000 DEG C, and viscosity is strong, and the sulfate of molten state is attached to when on boiler heat exchange tube wall,
The waste gas of sulfate high temperature corrosion, the combustion-supporting glass furnace discharge of regular air is easily caused to boiler tube wall very big difference, so
All-oxygen combustion glass furnace not directly uses ordinary air combustion waste heat boiler of glass furnace.
The content of the invention
The invention aims to solve fully can not rationally utilize all-oxygen combustion glass furnace waste gas residual heat at this stage
Shortcoming, and a kind of waste heat boiler of the all-oxygen combustion glass furnace for proposing.
To achieve these goals, present invention employs following technical scheme：
A kind of waste heat boiler of all-oxygen combustion glass furnace, it is characterised in that：Including boiler setting, in the relative both sides of boiler setting
Smoke-intake pipe and pipe are respectively equipped with, are connected on smoke-intake pipe to cold wind butterfly valve, Crust blocks pipe bundle, crust block pipe are provided with smoke-intake pipe
Beam connects drum by pipeline, and one group of dividing plate is provided with boiler setting, and boiler setting is divided into serpentine channel, enters cigarette by dividing plate
Pipe and pipe are separately positioned on the two ends of serpentine channel, and an ash is equipped with the downside of the boiler setting of each dividing plate both sides
Bucket, and it is equipped with one group of heat-exchanging tube bundle in each dividing plate both sides.
On the basis of above-mentioned technical proposal, there can be technical scheme further below：
The boiler setting is U-shaped flue, and the smoke-intake pipe and the pipe are arranged under U-shaped flue corresponding side
Side.
The flue-gas temperature that the smoke-intake pipe is passed through is 1000 DEG C, cold wind is passed through to cold wind butterfly valve from described, flue-gas temperature
It is down to 590 DEG C -610 DEG C.
The corresponding heat-exchanging tube bundle in each described dividing plate both sides is corresponded to and is connected in same bobbin carriage, each heat exchanger tube
Shu Jun is connected in the bobbin carriage by ventilation beam.
The heat-exchanging tube bundle includes that the superheater set gradually by the smoke-intake pipe to the direction of the pipe exchanges heat
Restrain, evaporator changes heat-exchanging tube bundle and economizer changes heat-exchanging tube bundle.
The level height of the heat-exchanging tube bundle in the same bobbin carriage is identical.
The Crust blocks pipe bundle is evaporation convection heat-exchanging tube bundle.
It is to consider that all-oxygen combustion glass furnace flue-gas temperature is high that smoke-intake pipe is set to cold wind butterfly valve（1000℃）, sulfuric acid in flue dust
Salt content is higher, and flue dust is in molten state under the condition of high temperature, is easily attached on boiler heat exchange pipe, influences heat transfer effect, so logical
Cross and convert the mode of cold wind flue-gas temperature is reduced to 600 DEG C or so, reduce flue dust viscosity, mitigate dust stratification, moreover it is possible to reduce boiler material
Material grade, reduces cost.
The advantage of the invention is that：Present apparatus simple structure, effectively using the fume afterheat of glass furnace, improves waste heat boiler
Reliability, production cost is saved, while reducing the flue dust in tail gas, it is to avoid sulfate causes to boiler high temperature rotten in flue dust
Erosion, the tail gas after treatment is small to air pollution, meets the discharge standard of country.
Brief description of the drawings
Fig. 1 is basic structure schematic diagram of the invention.
Specific embodiment
In order that the present invention becomes more apparent, the present apparatus is described in detail below in conjunction with accompanying drawing, tool described herein
Body embodiment is only used to explain the present invention, is not intended to limit the present invention.
As shown in figure 1, a kind of waste heat boiler of all-oxygen combustion glass furnace that the present invention is provided, including boiler setting 1, boiler
Furnace wall 1 is a square U-shaped flue, and dividing plate 8 is provided with vertically in the both sides cavity of U-shaped flue, each dividing plate 8
Downside is both connected on the inwall on the downside of boiler setting, and the U-shaped flue shape of two dividing plates 8 and boiler setting 1 itself is pot
The cavity of stove furnace wall 1 is divided into serpentine channel, and smoke-intake pipe 2 and pipe 3 are connected respectively at the two ends of serpentine channel, each every
The downside of boiler setting 1 of the both sides of plate 8 is equipped with an ash bucket 9, and is equipped with three settings side by side up and down in each both sides of dividing plate 8
