Loop shaped shaft kiln and co-fired lime calcining method
The invention provides a loop shaped shaft kiln and a co-fired lime calcining method, and belongs to the technical field of lime calcining. The loop shaped shaft kiln comprises a shaft kiln body and an inner kiln body. The inner kiln body is arranged in the shaft kiln body. Between the inner kiln body and the shaft kiln body, an annular cavity namely a calcining region is formed. The loop shaped shaft kiln also comprises a driving blowing system. The driving blowing system comprises an injector, an air extraction cylinder, a driving fan, and a heat exchanger. The injector is arranged on the bottom of the inner kiln body and ejects flows upwards to form a negative pressure on the bottom of the inner kiln body. The driving fan is used to extract air out from the shaft kiln body and deliversthe air to the injector, the injector sprays out the air, and the heat exchanger is arranged on the exterior of the shaft kiln body, is used to cool the air extracted from the shaft kiln body, and delivers the air to the injector, which sprays out the air. By arranging the inner kiln body in the shaft kiln body, an annular cavity namely a calcining region is formed between the inner kiln body andthe shaft kiln body, thus the air flow becomes uniform, and the materials can be uniformly calcined.
本发明提供一种环套形竖窑及混烧石灰煅烧方法，属于石灰煅烧技术领域，环套形竖窑包括竖窑本体和内窑体，内窑体设置在所述竖窑本体内，所述内窑体和竖窑本体之间的环形空腔形成煅烧区；所述环套形竖窑还包括驱动鼓风系统，所述驱动鼓风系统包括：喷射器、抽风筒、驱动风机、换热器，喷射器设置在内窑体的底部，用于向上喷射引流以使内窑体底部形成负压；驱动风机用于使竖窑本体内的气体从抽风筒抽出并循环至所述喷射器处喷出；换热器设置在竖窑本体的外部，用于使从竖窑本体抽出的气体降温后循环至喷射器处喷出。本发明在竖窑本体内设置内窑体，内窑体与竖窑本体之间的环形空腔形成煅烧区，使得通风均匀以实现物料的均匀煅烧。
