捷尔任斯基钢铁厂研制和采用了一种清理200和400吨平炉蓄热室格孔的装置。这种装置是通过由三个喷嘴(按两层设置时,喷嘴数量可增加)供给高压空气-水混合剂来清理格子砖上的沉渣。喷嘴中心线之间的距离等于格孔中心线间的距离。同心设置的可供应4～5个大气压高压水的外管a(见图)和接自干线可供应同样压力的压缩空气的内管б分别接到集管B和r上。通过这两个集管水经压缩空气雾化后送
Dzerzhinsky Steel developed and adopted a device for cleaning the cells in the 200 and 400-ton hearth regenerators. This device cleans sediment on the checkerboard by supplying a high pressure air-water mixture from three nozzles (the number of nozzles increases when two layers are provided). The distance between the nozzle centerlines is equal to the distance between the centerlines of the cells. The concentric outer tube a (see picture) which can supply 4 ~ 5 atmospheres of high pressure water and the inner tube б which is connected with compressed air from the main line for the same pressure are respectively connected to the headers B and r. Through these two header water atomized by compressed air back
