A Coke Quenching Equipment and Process with Controllable Thin Layer Turning to the Bottom

Abstract

The invention provides a novel thin-layer rotary-hearth controllable coke quenching device and technique. The rotary-hearth rotary-hearth controllable coke quenching device comprises a rotary hearth furnace body (1), a plurality of oriented fluid directors (31), a plurality of overturning fluid directors (32) and a spray device (4), wherein the rotary hearth furnace body (1) comprises a rotatable furnace shaft (11) and a furnace cover (12) fixed above the furnace shaft (11); the furnace shaft (11) is connected with the furnace cover (12) through a first water seal tank (22) in a sealing mode; a discharge pipe (111) is connected with a material collection pipe (13) through a second water seal tank (21) in a seal mode; the oriented fluid directors (31) and the overturning fluid directors (32) are positioned in the cavity of the furnace shaft (11); and the spray device is installed on the inner side of the furnace cover (12). The rotary-hearth rotary-hearth controllable coke quenching device can control the water content of the thermosetting substance and the temperature of the outlet thermosetting substance, implement quick cooling and uniform cooling, and avoid the phenomenon of spontaneous combustion of semicoke in the cooling process.

Description

technical field [0001] The invention relates to semi-coke cooling equipment and technology, in particular to a new type of coke quenching equipment and technology with controllable bottom-turning thin layer. Background technique [0002] Lignite is the mineral coal with the lowest degree of coalification. It is a brown-black, dull low-rank coal between peat and bituminous coal. It is rich in volatile matter and easy to burn and smoke. The world's lignite resources account for about 1 / 3 of the world's total coal resources. my country's lignite reserves also account for more than 1 / 8 of the country's total coal reserves, mainly distributed in eastern Inner Mongolia and eastern Yunnan, and a small amount in northeast and southern China. Lignite is not suitable for long-term storage and long-distance transportation due to its high moisture content, high volatile content, low calorific value, and high spontaneous combustion characteristics. It has long been regarded as a low-qua...
