High-temperature molten slag pelletizing device
The invention provides a high-temperature molten slag pelletizing device. The high-temperature molten slag pelletizing device comprises a pair of rollers, a shell, a supporting device, a deslagging roll and the like. The roller pair is composed of two exactly identical rollers which are parallelly arranged, are tangent and rotate reversely. Each roller is composed of an outer barrel and an inner barrel, wherein a cooling water pipe is arranged in an upper half part of an annular cavity between the outer barrel and the inner barrel, a plurality of nozzles are arranged on the cooling water pipe,water in the cooling water pipe is sprayed to the roller through the nozzles, and the temperature of the outer surface of the outer barrel does not exceed 100 DEG C, so that it is ensured that high-temperature creep does not occur on a roller material; and a lower half part of the annular cavity between the outer barrel and the inner barrel forms a water cavity with a certain height water level.On the one hand, the device pelletizes high-temperature molten slag to recover part of heat. On the other hand, the temperature of a slag layer on the surface of each roller before the slag layer reaches the deslagging roll and is extruded, peeled and crushed does not exceed 850 DEG C, the slag has been fully cooled to a curing temperature, and the lowest cooling rate of the slag is greater than 60 DEG C/s, so that the demand on rapid quenching is met.
本发明提出一种高温熔渣粒化装置，包括一对滚筒、外壳、支撑装置、除渣辊等。滚筒对由两个完全一样的、平行布置、相切且反向转动的滚筒组成。所述滚筒由外筒和内筒构成，外筒和内筒之间环形腔的上半部分设有冷却水管，冷却水管上设置有多个喷嘴，冷却水管内的水通过喷嘴喷向滚筒，使外筒外表面的温度不超过100℃，保证滚筒材料不会发生高温蠕变；下半部分形成水腔，积有一定高度的水位。本发明的装置，一方面将高温熔渣进行粒化，回收部分热量，另一方面，滚筒表面的渣层，在到达除渣辊被挤压剥离破碎之前，温度不超过850℃，炉渣已经全部被冷却到了固化温度以下，炉渣的最小冷却速率大于60℃/s，满足快速急冷的要求。
