Description

Уже известны устройства дл  подогрева вторичного воздуха во вращающихс  печах дл  обжига цемента и т. п. и дл  подачи воздуха навстречу потоку топочных газов.Devices for preheating secondary air in rotary kilns for cement burning, etc., and for supplying air to the flow of flue gases are already known.

От подобных устройств предлагаемое отличаетс  тем, что оно выполнено в виде нескольких концентрично расположенных в хвостовой части печи каналов, между которыми наход тс  каналы дл  отвэда продуктов горени .The proposed device differs from such devices in that it is made in the form of several channels concentrically located in the tail part of the furnace, between which there are channels for the discharge of combustion products.

На фиг. 1 схематически изображен продольный разрез вращающейс  печи дл  обжига цемента и т. п. с устройством дл  подогрева вторичного воздуха, на фиг. 2 - продольный разрез устройства дл  подогрева воздуха, на фиг. 3 - р зрез по АВ фиг. 2.FIG. Figure 1 shows schematically a longitudinal section of a rotary cement kiln, etc., with a device for preheating secondary air; FIG. 2 is a longitudinal section of the air preheater; FIG. 3 shows an AB view of FIG. 2

Корпус 10 вращающейс  цементной печи установлен на подшипниках 15 и примыкает к стенка 14 разовой камеры 7. В хвостовой части печи монтируетс  устройство 11 дл  подогрева вторичного воздуха, выполненное в виде нескольких концентричных каналов 2, между которыми наход тс  каналы 3 дл  отвода продуктов горени . По трубе 9 под компрессорным давлением подаетс  щламм. Воздух подаетс  вентил тором 6 по воздухопроводу 5 в коллектор 4. Устройство 11 крепитс  к корпусу печи трубами 13. Между печью и воздушной камерой наход тс  асбестовые прокладки 16. В передней торцевой стенке печи расположена горелка 1. Над газовой камерой установлена дымова  труба 8.The housing 10 of the rotary cement kiln is mounted on bearings 15 and is adjacent to the wall 14 of the disposable chamber 7. In the tail part of the furnace, a device 11 for heating secondary air is made, consisting of several concentric channels 2, between which there are channels 3 for exhausting combustion products. Schlamm is supplied through pipe 9 under compressor pressure. Air is supplied by the fan 6 through the air duct 5 to the collector 4. The device 11 is attached to the furnace body by pipes 13. There are asbestos gaskets 16 between the furnace and the air chamber. A burner 1 is located in the front end wall of the furnace.

На наружные стенки воздуишых каналов 2 устройства //, омываемых отход щими газами печи, разбрызгиваетс  шламм, подаваемый по трубе 9 под давлением в 1-2 атмосферы . Таким образом вращающа с  цементна  печь вместо одной поверхности дл  сушки, расположев ной по внутренней части ее дилиндра , имеет несколько поверхностей, расположенных равномерно по живому сечению хвостовой части печи , причем суммарна  поверхность по сравнению с существующей возрастает в два-три раза.The external walls of the air channels 2 of the device //, washed by the furnace exhaust gases, are sprayed with sludge supplied through the pipe 9 under a pressure of 1-2 atmospheres. Thus, a rotary cement kiln instead of one surface for drying, located on the inside of its dilindra, has several surfaces evenly spaced across the living section of the kiln tail, with the total surface compared to the existing one increasing two to three times.

Воздух, проход  через воздушные каналы, подогреваетс  отход щимиThe air, the passage through the air ducts, is heated by waste
