Abstract
1. Способ охлаждения горячего сыпучего материала, подвергшегося тепловому воздействию в промышленной обжиговой печи, такой как вращающаяся обжиговая печь (3) для производства цементного клинкера, при выполнении которого горячий материал из обжиговой печи (3) подают на решетку (21) холодильника (1), где через по меньшей мере один канал (28) охлаждающего газа направляют охлаждающие газы сквозь щели (20) в решетке для охлаждения горячего материала и где сжатый воздух может быть вдут в материал, расположенный на решетке (21), отличающийся тем, что сжатый воздух вдувают в канал (28) охлаждающего газа. ! 2. Способ по п.1, отличающийся тем, что по меньшей мере часть сжатого воздуха, вдуваемого в канал (28) охлаждающего газа, направляют сквозь щели (20) в решетке (21) в материл, расположенный на решетке (21). ! 3. Способ по п.1 или 2, отличающийся тем, что сжатый воздух вдувают под углом α, меньшим 90° относительно оси канала (28) охлаждающего газа. ! 4. Способ по п.1 или 2, отличающийся тем, что сжатый воздух вдувают под углом α, меньшим 10° относительно оси канала (28) охлаждающего газа. ! 5. Способ по п.1 или 2, отличающийся тем, что сжатый воздух вдувают под углом α, составляющим 0° относительно оси канала (28) охлаждающего газа. ! 6. Холодильник (1) для осуществления способа по пп.1-5, содержащий решетку (21), предназначенную для приема и поддержания горячего материала из обжиговой печи (3), по меньшей мере один канал (28) охлаждающего газа, связанный со щелями (20) в решетке для направления охлаждающих газов в горячий материал (2), и систему (25, 26) сжатого воздуха для вдувания сжатого воздуха в материал (2), находящийся на решетке (21), отличающийся тем, что он содержит средств� 1. The method of cooling hot bulk material subjected to heat in an industrial kiln, such as a rotary kiln (3) for the production of cement clinker, in which the hot material from the kiln (3) is fed to the grate (21) of the refrigerator (1) where through at least one cooling gas channel (28) cooling gases are directed through slots (20) in the grill for cooling the hot material and where compressed air can be blown into the material located on the grill (21), characterized in that th air is blown into the cooling gas channel (28). ! 2. The method according to claim 1, characterized in that at least a portion of the compressed air blown into the cooling gas channel (28) is directed through slots (20) in the grate (21) into a material located on the grate (21). ! 3. The method according to claim 1 or 2, characterized in that the compressed air is blown at an angle α less than 90 ° relative to the axis of the channel (28) of the cooling gas. ! 4. The method according to claim 1 or 2, characterized in that the compressed air is blown at an angle α less than 10 ° relative to the axis of the channel (28) of the cooling gas. ! 5. The method according to claim 1 or 2, characterized in that the compressed air is blown at an angle α of 0 ° relative to the axis of the cooling gas channel (28). ! 6. The refrigerator (1) for implementing the method according to claims 1-5, comprising a grate (21) designed to receive and maintain hot material from the kiln (3), at least one channel (28) of cooling gas associated with slots (20) in the grill for directing cooling gases into the hot material (2), and a compressed air system (25, 26) for injecting compressed air into the material (2) located on the grill (21), characterized in that it contains means�
