Description
Technical field
The utility model belongs to building materials industry production field, particularly relates to heavy clay industry calcination equipment field, particularly a kind of baked brick tunnel kiln cooling system, for the production of fired brick (building block).
Background technology
Traditional fired brick (building block) tunnel cave, current most type of cooling adopts afterbody wicket axial flow blower to blast the mode of natural wind by part cooling.Under the effect of kiln hood smoke exhaust fan negative pressure, kiln tailing axle flow fan malleation, a part of kiln tail cooling air along kiln road inner chamber everywhere Clearance Flow forward, be supplied to clinkering zone combustion air; Another part extracts the hot gas after heat exchange at salband be delivered to drier by taking out waste heat fan.Although this kind of type of cooling simple process, due to only at afterbody wicket air feed, cold wind is large along the kiln length direction pressure loss, and cooling effect is poorer more forward.It is combustion-supporting that the parts of these wind enters clinkering zone, but because hack resistance is large, make the combustion air volume entering clinkering zone not enough, thus to be easy to cause in goods fuel can not Thorough combustion, combustion zone also can be made time serious to drift about to salband, make goods be easy to occur the defects such as evil mind, and cause kiln discharge products temperature too high, waste heat energy.
In addition, above-mentioned cooling, fume exhausting type make kiln hood smoke exhaust fan load excessive, easily form kiln hood negative pressure higher, easily make a large amount of cold wind enter in kiln, destroy the inner thermal regulation of tunnel cave, are unfavorable for that goods burn till.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of baked brick tunnel kiln cooling system, the abundant heat exchange of fired brick (building block) goods can be made, Homogeneous cooling, in kiln thermal regulation easily regulate and control and can provide sufficient to drier, clean thermal source and provide sufficient combustion air for clinkering zone, ensure the quality of production of fired brick (building block) goods, economize energy.
For realizing above-mentioned technique effect, the utility model provides a kind of baked brick tunnel kiln cooling system, it comprises chilling wind system, tail quenching system and take out residual heat system, after chilling wind system is arranged on clinkering zone, before taking out residual heat system, tail quenching system and take out residual heat system and be arranged on kiln afterbody, after tail quenching system is arranged on and takes out residual heat system, described chilling wind system comprises chilling blower fan, some chilling wind pipelines and control valve, chilling wind pipeline comprises chilling wind main pipeline and some chilling wind branch pipe(tube)s, chilling wind main pipeline connects chilling blower fan and chilling wind branch pipe(tube), chilling wind branch pipe(tube) connects the ventilating opening on tunnel cave top and the ventilating opening of kiln side wall, every bar chilling wind branch pipe(tube) all arranges control valve, the spacing of adjacent two chilling wind branch pipe(tube)s is equal, its spacing equals the spacing of hack on kiln car, described tail quenching system comprises tail air-cooler, some tail cold air ducts and control valve, tail cold air duct comprises tail cold wind main pipeline and some tail cold wind branch pipe(tube)s, tail cold wind main pipeline connects tail air-cooler and tail cold wind branch pipe(tube), tail cold wind branch pipe(tube) connects the ventilating opening on tunnel cave top and the ventilating opening of kiln side wall, every bar tail cold wind branch pipe(tube) all arranges control valve, the spacing of adjacent two tail cold wind branch pipe(tube)s is equal, and its spacing equals the spacing of hack on kiln car, take out residual heat system be arranged on tail quenching system before, after chilling wind system, take out residual heat system to comprise and take out waste heat fan, somely take out waste heat pipeline and control valve, take out waste heat pipeline to comprise and take out waste heat main pipeline and somely take out waste heat branch pipe(tube), take out the connection of waste heat main pipeline take out waste heat fan and take out waste heat branch pipe(tube), take out the ventilating opening that waste heat branch pipe(tube) connects tunnel cave top, take out on waste heat branch pipe(tube) at every bar and all control valve is set.
Described chilling wind system also comprises PID auto temperature controlled system, and chilling wind blower fan is variable-frequency motor, according to the size of the temperature automatic adjustment wind supply quantity of setting, reaches temperature automatically controlled object.
Due to chilling wind system next-door neighbour clinkering zone, it is combustion-supporting that high-temperature hot-air can enter rapidly clinkering zone, for burning provides enough combustion airs.Chilling wind system adopts top, side wall air supply mode simultaneously, ensure that combustion air evenly enters clinkering zone on Yao Dao cross section, avoid or slow down large cross-section tunnel kiln because combustion air is not enough, skewness causes the defect that in goods, fuel can not burn completely.Decrease the quantity of discharge flue gas simultaneously, reduce the treatment quantity of flue gas purifying equipment significantly.
This cooling system by VFC blower fan or controlling opening of valve to blasting cold blast rate, extract hot blast rate and control, reach the object regulating tunnel cave cooling section thermal regulation according to demand.
