Embodiment Construction
[0009] The attached figure shows a cross-sectional view of a clinker cooler 1 for cooling a cement clinker bed 2 supported by a ventilated bottom 3, subjected to a supply of cooling gas from the side walls 5, end walls 6 and the bottom compartment 4 of the bottom 7 are directed to and flow upwards through the aerated bottom 3 and the cinder bed 2 .
[0010] In order to be able to inspect devices such as airflow regulators, drive tools, hydraulic components etc. (not shown) located in the area of the compartment 4 during operation of the clinker cooler 1, due to the comparative Poor visibility, these devices are not visible, whereas the shown clinker cooler 1 according to the invention comprises a plurality of strips extending from one side wall 5 of the compartment 4 through the compartment 4 to the other side wall. An inspection channel 8 extends through and is provided with an inspection opening 9 .

A description is given of an apparatus (1) for treating a bed (2) of particulate material which is supported by an aeration bottom (3), subject to the application of a conditioning gas being directed to and flowing up through the aeration bottom (3) and the material bed (2) from an underlying compartment (4) which comprises side walls (5), end walls (6) and a bottom (7). The apparatus is peculiar in that it comprises a number of inspection channels (8) which extend into the compartment (4) from its side walls (5), end walls (6) or bottom (7) and being provided with a number of inspection openings (9). Hence it will be possible during the operation of the apparatus to inspect the equipment in a significantly extended area of the compartment. This is due to the fact that the inspection channels make it possible to inspect equipment located in areas of the compartment which are not visible due to poor visibility from windows located in the side walls of the compartment.
Description
technical field [0001] The invention relates to an apparatus for treating a bed of granular material supported by an aeration bottom, supplied with a conditioning gas directed from a bottom compartment comprising side walls, end walls and a bottom , and flow upward through the aerated bottom and material bed. Background technique [0002] There are many examples in the industrial field of devices featuring ventilated bottoms. Non-limiting examples thereof include fluidized bed reactors, chemical reactors, drying units, gas-solid heat exchangers, and others. A common feature of these devices is that they may comprise different devices in compartments below the vented bottom, which are not directly accessible or visible during operation. Such means may include, for example, fluid regulators, drive means, hydraulic components etc. for segmental adjustment of air flow as described in EP0848646. During start-up and operation of the above-mentioned equipment, it may be desirabl...
