Gas generator device for recovering sensible beat of slag obtained from gas producer

Abstract

The invention discloses a coal gas producer unit for reclaiming gas-making slag sensible heat. The coal gas producer unit comprises a furnace body, a grate, a furnace slag chamber, an ascending coal gas pipe valve, a descending coal gas pipe valve, a downblow steam pipe valve, an upblow steam pipe valve, a blast air valve, a vent valve, a furnace slag cooling water pipe valve, a drain pipe, and adrain valve, wherein, the upper part of the furnace slag chamber is connected with the furnace slag cooling water pipe valve through a water spray nozzle, and the upblow steam pipe valve and the furnace slag cooling water pipe valve are linked and are synchronously opened and closed. The structure and the process are adopted, so the furnace slag cooling water pipe valve and the upblow steam pipe valve are synchronously opened at an upblow stage and a secondary upblow stage, cooling water is sprayed on high-temperature furnace slag through a nozzle arranged on the upper part of the furnace slag chamber, and the produced steam enters the furnace body along with upblow steam to generate water gas and enter a gas storage holder. The coal gas producer unit avoids the generation of the steam ata blowing stage, reduces the reaction that water vapor and carbon generate CO and H2 at the blowing stage, and fully utilizes the afterheat of the furnace slag.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to a coal gas generator capable of recovering the sensible heat of high-temperature gas-making furnace slag while producing water gas with anthracite lumps. Background technique [0002] At present, in the synthetic ammonia production process, the performance of the gasifier is directly related to the production cost, because the water gas is produced in the gasifier. The production process steps of the conventional gasifier mainly include: blowing - recovery - up blowing - down blowing - secondary up blowing - blowing clean process. The conversion of these processes is realized through the switching of valves. In order to increase the production of water gas, most of the efforts are made on how to optimize these processes. There is less research on how to make full use of the waste heat of a large amount of high-temperature slag generated during the operati...
