新型煤气化装置中的煤浆喷头

Coal slurry spray head in novel coal gasification device

Abstract

The utility model discloses a coal slurry spray head in a novel coal gasification device, which comprises a wearproof end and a diversion end which are mutually and movably connected, wherein the wearproof end is in threaded connection with the diversion end, and the wearproof end and the diversion end are respectively provided with a positioning bolt. The coal slurry spray head in the novel coal gasification device is a detachable spray head which consists of the wearproof end and the diversion end, and is convenient for surfacing and processing of the inside of the wearproof end; when the coal slurry spray head is replaced, only the wearproof end is replaced, and materials and expenses can be saved; an external oxygen annular space between the coal slurry spray head and an epoxy spray head can be adjusted by rotating the wearproof end without replacing an octagonal gasket; and the number of positioning threaded holes at the diversion end is more, the adjusting precision of the annular space is higher.
本实用新型公开了一种新型煤气化装置中的煤浆喷头,其包括有相互之间活动连接的耐磨端及导流端,所述耐磨端和所述导流端为螺纹连接,所述耐磨端和所述导流端上还设置有一个以上的定位螺栓。本实用新型的一种新型煤气化装置中的煤浆喷头是由耐磨端与导流端组成的可拆式喷头,便于耐磨端内部的堆焊和加工;更换煤浆喷头时,只需更换耐磨端即可,能够节省材料费用;煤浆喷头和环氧喷头的外氧环隙,可以通过旋转耐磨端来调整,不必再更换八角垫片;导流端上定位螺纹孔的数量越多,环隙调整精度越高。
