    • Gegenstand der Neuentwicklung bildet ein Wirbelschicht-Wärmeaustauscher für fließfähige Schüttgüter, mit einem Behälter für das Schüttgut, der mit einem luftdruchlässigen Anströmboden (3) versehen ist, sowie mit einer regelbaren Einrichtung für die Gutzuführung. Ein derartiger Wärmeaustauscher findet Anwendung beispielsweise als Kühler für die Asche in einem Kraftwerk. Um einen besonders hohen Wärmeübergang zwischen dem Wirbelgas und dem Schütt gut bei geringen baulichen Abmessungen zu ermöglichen und damit nur eine geringe Verweildauer des Schüttgutes im Wärmeaustauscher ist nach der Erfindung vorgesehen, das über dem Anströmboden (3) Gitterroste (8, 20, 21) angeordnet sind, die drehbeweglich oder horizontal hin- und herbewegbar gelagert sein können. Dafür sind die Gitterroste vorzugweise gemeinsam mit einer motorisch angetriebenen Welle (10) verbunden, wobei sie auch übereinander liegend angeordnet sein können.

    • PURPOSE:To reduce the horizontal and downward flows of a gas within a solid particle layer at the boundary of operation zones by a method wherein the interior of the circular grate is divided by partition plates to thereby form a plurality of solid substance housing chambers. CONSTITUTION:The solid substance housing chambers 4 are defined by side walls 2, lower split grids 7 and the partition plates 8 dividing radially the space between the side walls 2 and stand side by side in the circumferential direction. The upper edge of each partition plate 8 is located lower than the surface A of a solid layer by a height C by which the shearing force of the solid particle layer reduces rapidly among the partition plates 8. Further, an upper seal plate 12 and a lower seal plate 13 are provided between the operation zones, for example, a heating zone and a cooling zone so as to sandwich the circular grate. In addition, a number of labyrinthine seal plates 11 are suspended from the upper seal plates and come into contact with the upper surface of the solid particle layer within each of the solid substance housing chambers 4 so that the heating zone and the cooling zone are isolated from each other airtight. The length G of the upper seal plate 12 is more than 1.5 times the fixing pitch E of the partition plate 8 and the length of the lower seal plate 13 is approx. two times the fixing pitch of the partition plate.
    • 目的:通过圆形格栅的内部由隔板分隔从而形成多个固体物质容纳室的方法,减少操作区边界处固体颗粒层内气体的水平和向下流动。 构成:固体物质容纳室4由侧壁2,下分隔栅极7和分隔板8限定,侧壁8沿着圆周方向并排放置在侧壁2之间的空间。 每个隔板8的上边缘位于比固体层的表面A低的高度C处,固定颗粒层的剪切力在分隔板8之间迅速降低。此外,上密封板12和 下部密封板13设置在操作区域,例如加热区域和冷却区域之间,以夹持圆形格栅。 另外,多个迷宫式密封板11从上密封板悬挂起来,与每个固体容纳室4内的固体颗粒层的上表面接触,使得加热区和冷却区隔离 彼此气密。 上密封板12的长度G大于分隔板8的固定间距E的1.5倍,下密封板13的长度约为。 是隔板的固定间距的两倍。

    • PURPOSE:To efficiently cool clinker by a structure wherein a stepped part is formed in a grating bed in its low temperature zone and splinkling of water is applied at the stepped part. CONSTITUTION:Cooling water is sprayed through spray nozzles 39 against the clinker falling down from an upper step grating bed part 20 to a low step grating bed part 21, while cooling air is blasted through vent holes 41. The cooling water is mixed with the cooling air and, after that, blasted against the clinker in the form of mist in order to cool the clinker. Because the cooling water turns into mist and no local spraying of the cooling water occurs, no water drips from the clinker. Because the cooling water is sprayed against the falling clinker at the stepped part 19, the cooling water is also sprayed over the clinker, which was located at the uppermost part of the clinker layer in the upper step grating bed part 20 and has high temperature.
    • 目的:通过其阶梯部分在其低温区域的格栅床中形成并且在台阶部分施加水的结构来有效地冷却熟料。 构成:通过喷嘴39将冷却水喷射到从上阶格栅床部分20落下的熟料到低阶格栅床部分21,同时通过通气孔41喷射冷却空气。冷却水与冷却 空气,之后,以薄雾的形式对熟料进行了爆炸,以冷却熟料。 由于冷却水变成雾状,没有冷却水局部喷洒,所以没有水从熟料滴下。 由于在台阶部19将冷却水喷洒在落下的熟料上,所以冷却水也被喷洒在位于上阶格栅床部20的熟料层的最上部的熟料上,具有高温。
