Cooler

The present invention relates to a cooler for cooling particulate material which has been subjected to heat treatment in an industrial kiln, such as a rotary kiln for manufacturing cement clinker. This cooler comprises an inlet, an outlet, end wall, side walls, a bottom and a ceiling, at least three reciprocating supporting lanes for receiving, supporting and transporting the material to be cooled, the lanes are moving following the walking floor principles as well as means for injecting cooling gas into the material through grate plates in the lanes. The present invention relates to an increasing in the vertical shearing height, and still having stationary clinker on top of the grate plates, see FIG. . The length of the tilted element () is L and the distance () between two devices is G. The angle between the element () and horizontal is alfa (). Since the air is distributed evenly from the full grate plate area it is obvious and understandable that the L*cosines(alfa) becomes a shadow area where all air from the region in the grate plate will go through the stationary clinker and leave the tip of L at this one point only. Again, it is not good for the heat recuperation to have a shadow area too big—as it, again, gives an uneven air flow through the clinker bed, damaging the heat recuperation. The vertical shearing height is on the other hand L*sinus(alfa). But if alfa becomes too large (approximately above 60 deg.), it will block the sliding effect, as now the clinker will not get forced over the plate's L-part, and then the wished larger vertical shearing is not achieved. It is hereby a compromise to get a certain vertical shearing: L*sinus(alfa) by not having a too large shadow area L*cosines(alfa), but still having the angle alfa so low that the clinker will slide at L—see FIG.

Cooler for cooling material consisting of macroparticles

Сущность: охладитель (1) для охлаждения материала, состоящего из макрочастиц и выходящего из печи, в котором материал распределяется в виде слоя по стационарной опорной поверхности (11), имеющей форму поддона, в то время как охлаждающий газ, такой как атмосферный воздух, вдувается вверх сквозь слой материала из инжекторов, равномерно распределенных по поддону. Материал транспортируется вперед по опорной поверхности (11) через охладитель (1) с помощью отдельного механического устройства (17) для конвейерной транспортировки. Таким образом, можно разделить три функции такого охладителя, а именно обеспечение опоры для материала, распределение охлаждающего газа по опорной поверхности и транспортировку материала вперед по опорной поверхности.

In controlling the flow of air provided by the clinker cooler and fed to the furnace and the combustion chamber placed above the furnace in a cement mfg. plant, process is characterised in that the air flow is divided into two currents which followed different paths through the clinker layer and are directed towards the furnace and the combustion chamber respectively, while the thickness of the clinker layer transversed by one of the currents is controlled to obtain the desired distribution of air between the two currents. Improved distribution of air between combustion chamber and furnace is obtd. without forming accumulations in the sheath of the furnace leading to blockages.

Two stage cooler for cement clinker - with intermediate grinding and separations to remove fines prior to further cooling

Cement clinker is cooled, on leaving the clinkering furnace, in two stages with a crushing step between the two stages, and the crushed product is separated into >=2 fractions of different grain sizes. The coarser fraction(s) is (are) then cooled in a tank heat exchanger by air flowing counter current to or across the path of the particles and the finer fraction which may also be separately cooled, is subsequently remixed with the coarser fraction(s). Process avoids or considerably reduces the pick up of fine dust particles by the cooling air, which thus does not have to be de-dusted prior to release to the atmosphere.

Method and apparatus for the simultaneous transport and heating (or cooling) of bulk materials

Screen cooler - for cement clinker with air totally recirculated

In a process for screen cooling a furnace which recycles part of the cooling air, that part of the air which is not used in the furnace is passed through a heat exchanger, brought to a convenient temp. and recycled through the cooler. The total recirculation of the part of the air not used for combustion avoids the need to eliminate dust if it were exhausted to atmosphere. The invention is particularly applicable to a rotary cement kiln and the agglomeration of other minerals. Preferably a portion of the cooling air which has passed through the coolest part of the cooler is recycled to the hottest part and introduced together with fresh air, the two streams being directed towards the furnace. Air travelling the middle of the cooler is passed through a heat exchanger and recycled. The exchanger may use external air and/or refrigerating liquids.

Bulk-material cooler for cooling hot material to be cooled

The aim of the invention is to design a bulk-material cooler, particularly one for cooling cement clinker, which operates according to the walking floor principle, so that its cooling grate can be composed of a multitude of ventilated cooling grate modules, which can be assembled in an easy and variable manner, in order to obtain large lengths and widths of the cooler. When these cooling grate modules move between an advancing and returning position, even lateral and/or height offset of the guiding elements can be compensated for in a kinematic manner. To this end, the invention provides that the cooling grate, when viewed over the length and width of the cooler, is composed of a multitude of modules (13, 14) ventilated with cooling air (18). The coupling of the cooling grate modules (13, 14) of each longitudinal row of cooling grate modules is effected by an articulated joint (21, 22).
