Fixed layer intermittent mixing gas making device

一种固定层间歇混合制气装置

Abstract

The utility model provides a fixed layer intermittent mixing gas making device. Inlets of upper coal gas recovery pipelines of a gas making furnace are inserted in a dry distillation layer inside a hearth; and pipeline wall cracks are arranged on the upper coal gas recovery pipelines and communicated with a blast pipeline at the bottom of the gas making furnace through a secondary air supplementary valve. A plurality of upper coal gas recovery pipelines are arranged on the gas making furnace. Secondary air can be supplemented for the dry distillation layer inside the hearth during the blowing stage; the partial afterheat of fume is also recovered while the pipelines are safely protected, and the thickness of the dry distillation layer is increased under the situation of maintaining the thickness of a normal gasifying layer, so that more heat is stored for blowing gas. The inlets of the coal gas recovery pipelines are inserted in the dry distillation layer inside the hearth, which is considered from angles of smooth transition of upper coal gas transmission and upper coal gas recovery; and when upper coal gas is recovered, the system resistance can not be increased.
本实用新型提供了一种固定层间歇混合制气装置,各制气炉的上行煤气回收管线进口插在炉膛内部的干馏层中,上行煤气回收管线上设有管道壁夹缝,管道壁夹缝通过二次空气补充阀与制气炉底鼓风管道相连通。各制气炉的上行煤气回收管线具有若干根。在吹风阶段能向炉膛内部的干馏层补充二次空气,在保护管线安全的同时也回收了烟气的部分余热,在维护正常气化层厚度的情况下,增加了干馏层的厚度,为下吹制气储备了更多的热量。煤气回收管线进口插在炉膛内部的干馏层之中,这是从进行上行煤气输送和上行煤气回收的平稳过渡角度考虑,在进行上行煤气回收时,系统阻力不会增加。
