Description
Technical field
Field of glass production technology is the utility model is related to, more particularly to a kind of waste heat boiler of all-oxygen combustion glass furnace.
Background technology
Glass furnace is a kind of to produce high temperature using fuel such as the natural gas that burns, heavy oil and melt the industry kiln of frit
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, waste gas caused by burning
Few, NOx content 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
Energy-saving and emission-reduction improve the important channel of product quality.
Call and further reduction production cost, China's glass furnace in response to national energy-saving emission reduction are largely 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 exhaust temperature melts 1 ton at 1000 DEG C or so
The about 650-800Nm of exhaust gas volumn caused by glass metal3/ 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, when the sulfate of molten state is attached on boiler heat exchange tube wall,
Sulfate high temperature corrosion is easily caused to boiler tube wall, the waste gas of the combustion-supporting glass furnace discharge of regular air has very big difference, so
All-oxygen combustion glass furnace not directly uses ordinary air combustion waste heat boiler of glass furnace.
Utility model content
The purpose of this utility model is in order to which solve at this stage can not be fully rationally using more than all-oxygen combustion glass furnace waste gas
The shortcomings that hot, and a kind of waste heat boiler of the all-oxygen combustion glass furnace proposed.
To achieve these goals, the utility model employs following technical scheme：
A kind of waste heat boiler of all-oxygen combustion glass furnace, it is characterised in that：It is relative in boiler setting including boiler setting
Both sides are respectively equipped with smoke-intake pipe and pipe, are connected on smoke-intake pipe to cold wind butterfly valve, Crust blocks pipe bundle is provided with smoke-intake pipe, coagulate
Slag tube bank connects drum by pipeline, and one group of dividing plate is provided with boiler setting, and boiler setting is divided into serpentine channel by dividing plate,
Smoke-intake pipe and pipe are separately positioned on the both ends of serpentine channel, and one is equipped with the downside of the boiler setting of each dividing plate both sides
Ash 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 at U-shaped flue corresponding side
Lower section.
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 heat-exchanging tube bundle is corresponding accordingly for each dividing plate both sides is connected in same bobbin carriage, each heat exchanger tube
Shu Jun is connected in the bobbin carriage by ventilation beam.
The superheater that the heat-exchanging tube bundle includes being set gradually by the direction of the smoke-intake pipe to the pipe exchanges heat
Tube bank, evaporator changes heat-exchanging tube bundle and economizer changes heat-exchanging tube bundle.
The level height of 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, which 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
Expect grade, reduce cost.
The utility model has the advantage of：The present apparatus is simple in construction, effectively utilizes the fume afterheat of glass furnace, improves waste heat
The reliability of boiler, production cost is saved, while reduce the flue dust in tail gas, avoided sulfate in flue dust and height is caused to boiler
Temperature corrosion, the tail gas after processing 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 present utility model.
Embodiment
In order that the utility model is more clearly understood, the present apparatus is described in detail below in conjunction with accompanying drawing, it is described herein
Specific embodiment only explaining the utility model, be not used to limit the utility model.
As shown in figure 1, a kind of waste heat boiler of all-oxygen combustion glass furnace provided by the utility model, including boiler setting 1,
Boiler setting 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 every
The downside of plate 8 is both connected on the inwall on the downside of boiler setting, the U-shaped flue shape of two dividing plates 8 and boiler setting 1 itself
The cavity of boiler setting 1 is divided into serpentine channel, smoke-intake pipe 2 and pipe 3 are connected respectively at the both ends of serpentine channel, every
The downside of boiler setting 1 of the individual both sides of dividing plate 8 is equipped with an ash bucket 9, and be equipped with each both sides of dividing plate 8 three it is side by side up and down
Serpentine channel is divided into first passage 15, second channel 16, third channel the 17, the 4th by the heat-exchanging tube bundle of setting, heat-exchanging tube bundle
Passage 18 and Five-channel 19, smoke-intake pipe 2 are connected to the lower section of first passage 15, and pipe 3 is connected under Five-channel 19
