Description
Technical field
The utility model relates to a kind of tunnel oven, it is specifically related to a kind of flue gas, waste heat is kept completely separate energy conservation and environmental protection and bakes bricks
Tunnel oven.
Background technique
China's brickmaking industry is more than 50 years existing using tunnel oven firing common brick, develops to mesh from 1.5 meters originally of light sections
10.5 meters of preceding large cross-section tunnel kilns, especially China's manufacturing industry transition and upgrade, all parts of the country have been eliminated large quantities of in succession in recent years
Backward small earth kiln, has created large quantities of tunnel ovens, and tunnel oven popularity rate has reached 50% or more at present.But at present
Until 98% or more factory be to be heat-fed the flue gas in tunnel oven sintering process toward drying kiln to dry adobe, although most of
Cooling Section of Tunnel Kiln is equipped with waste heat and takes out mouth, but full communicating kiln body, in tail portion, air inlet extracts waste heat and can greatly reduce
Roasting band amount of oxygen, influencing rate of roasting reduction yield must join during being sent to drying kiln and match since flue-gas temperature is higher
Natural wind adjusts temperature, and oxygen content is exceeded after this results in flue gas desulfurization, so all brick field flue gas emissions are all not achieved at present
Environmental requirement.
Traditional oxygen needed for tunnel oven sintering process (natural air) of baking bricks is entered from the tail end (vehicle end out) of kiln,
It is combustion-supporting by cooling zone, insulation belt, arrival clinkering zone.The high-temperature flue gas that burning generates all is sent to drying kiln.Partial roasting kiln
Although being equipped with the air lock for extracting waste heat in cooling zone, the waste heat extracted from cooling zone is also to enter natural air from tail portion,
Extracting waste heat just reduces the oxygen into roasting band, had not only influenced rate of roasting but also will cause roasting band anoxycausis, and can make to arrange
Carbon monoxide is superfluous in flue gas out.
The tunnel calcining kiln taking length that China's brickmaking industry is built at present is mostly between 100~120 meters, since centre does not have
Apparatus of oxygen supply makes the interior formation negative pressure of kiln go out vehicle end sucking natural air from calcining kiln, if kiln by the draft of smoke exhaust fan completely
The length built, the natural air entered from tail portion is excessive by adobe resistance, and roasting band oxygen can be made insufficient, influence yield, no
Adapt to the demand that China's brickmaking industry pursues high yield.Curtailment is devoted exclusive attention to output again so that ejecting common brick outside kiln also 300
DEG C or more, some is also being caught fire, and is ejected burned common brick outside kiln and is cooled down, a large amount of heat is made to be dispersed into air
In, it not only influences environment and also results in heat waste.
Summary of the invention
The utility model is provided with keeping blower at the top of heat preservation region, by supporting blower to high-temperature roasting zone
