    摘要: The present invention related in a grate plate for cooling and conveying of clinker intended to improve efficiency to meet the requirements of operation process as much as possible. Both in terms of cooling the clinker at high temperature up to 1,450 degrees Celsius by air blown pass through said grate plate via air opening which allowing of cooling air upward to clinker bed to reduce the temperature to 80 – 120 degrees Celsius at outlet end and the volume of hot air occurred from heat transfer between hot clinker and cooling air can be reuse as process heat in the system. Which the said heat exchange to operate in parallel with the conveying of clinker. The manner of the grate plate comprising the grate plate with air opening in cross section is trumpet venturi with smooth surface which means that no sharp corner. Which the said air opening is inclined for control air direction to forward movement as the same clinker conveying direction. By lower part of the air opening with wide and gradually narrow in sequence to the second part, which is middle part of the air opening that is the narrowest section and similar wide for a while until the last part, which is upper part of the air opening, will gradually be wide in sequence to the top of grate plate. the air opening designed with X1 or distance of middle part of the air opening and Xout or distance of upper part of the air opening to result in maximum air velocity at the end of trumpet venturi opening and more uniform cooling air flow through the air opening.

On the Rotating Reactor's (4) circuit are placed heaters, permanently fixed with said circuit, e.g. Electrical Heaters (9). Between Electrical Heaters (9) are distributed Thermal - Electrical Insulation Spacers (10). To Thermal - Electrical Insulation Spacers (10) are fixed Internal Ring Electrical Sliding Contacts (11). To Internal Ring Electrical Sliding Contacts (11) are connected Internal Electrical Connections (12) on one side, while on the other side - External Electrical Sliding Contacts (13), farther connected with Electrical Phase Conductors (14). The rotating surface of the Rotating Reactor (4) is covered in a Thermal Insulation Material Layer (15), and thereon a second Electrical Insulation Material Layer (16) is placed. The internal surface of the Rotating Reactor (4) is incorporated by a Spiral (17) of helical structure. The Versatile Waste Treatment Reactor is constructed such that it enables thermal and chemical treatment of various waste type groups individually or mixed, conducting thereon separately or jointly such processes as: thermal decomposition, thermocatalytic decomposition, partially pyrolysis and partially gasification or incineration. Simultaneously the Versatile Waste Treatment Reactor is constructed such that it enables continuous supply of process components thereto and continuous discharge of solid and gaseous reaction products therefrom, and enables its cleaning without the need to stop and open it.

    摘要: 本发明公开了一种用于窑法磷酸工艺中还原磷矿石的回转窑,包括窑体、窑头箱、窑尾箱和驱动窑体转动的驱动装置,在窑头处设有燃料烧嘴,在窑尾箱处设有进料管和一连接至外部水化塔的出口烟道,窑体的上部不设置风管,出口烟道设于以回转窑轴线为中心的窑体半径范围内,且出口烟道中的烟气输送方向与回转窑的轴线方向基本平行或呈小于45°的夹角。采用本发明的回转窑进行窑法磷酸工艺时,使原料从窑尾箱进入,点燃燃料烧嘴加热,磷矿石原料在高温条件下还原后生成出窑烟气,本发明使出窑烟气在进入出口烟道时不发生较大偏移,进而阻止窑尾处产生离心物理沉降,使窑气中的偏磷酸直接随出窑烟气进入水化塔。本发明可有效缓解回转窑窑尾结圈现象。
