Abstract

The invention relates to a composite pulverized coal gasifying technology in the field of coal chemical industry, in particular to a composite pulverized coal gasifying technology adopting a fluidized gasification technology and a slag entrain bed gasification technology in a coal gasification system, and solving the difficulties of complicated structure, huge investment, difficult maintenance, high energy consumption and high operation cost in the coal gasification system. The invention ensures that raw material coal is processed, conveyed and fed simply without special raw material coal gasification nozzles, and gas and slag are simply separated, thus the complexity of the coal gasification system is lowered, and the energy consumption and the manufacture and operation costs of the coal gasification system are reduced. The invention can be applied to various pulverized coal gasification processes.

Description

The composite powder Coal Gasification Technology
Technical field
The present invention relates to coal chemical technology.
Background technology
In coal chemical technology, quantity-produced coal gasification both domestic and external system, need complicated feed coal processing, delivery system, need technical sophistication, high temperature resistant, wear-resistant and corrosion resistant coal gasification nozzle, also need technology, high vapourizing furnace and the slag handling system of material requirements simultaneously, make that gasification system is very complicated, investment is huge, it is difficult to safeguard, energy consumption is high, running cost is very high, become one of important factor of restriction Coal Chemical Industry development.
Summary of the invention
The present invention is meant and adopts fluidized-bed gasification technology and slag entrained flow bed gasification technology simultaneously in a coal gasification system.Being primarily aimed in coal chemical technology coal gasification system needs complicated feed coal to handle, delivery system, need the big and high coal gasification nozzle of material requirements of technical difficulty, need technology, vapourizing furnace that material requirements is high and slag separation system, cause gasification system very complicated, invest huge, it is difficult to safeguard, the energy consumption height, the difficult problem that running cost is high, fluidized-bed gasification furnace and slag airflow bed gasification furnace serial connection technology are adopted in invention, usual manner advances coal, fine coal carries out entering the further high-temperature slag gasification of slag airflow bed gasification furnace after the elementary gasification in fluidized-bed gasification furnace, liquid slag flows into the slag cold shock naturally and discharges system from the vapourizing furnace bottom, pyroreaction gas leaves vapourizing furnace after by quench gas or cold shocking water cold shock cooling.Make that the feed coal charging is simple, need not the processing of special material coal, delivery system, need not special coal gasification nozzle, gas, slag separate simple.Thereby the complicacy of gasification system, the energy consumption that has reduced gasification system, manufacturing and running cost have been reduced.
Present technique can be applicable to various coal gasification processes.
Description of drawings
Accompanying drawing is a schematic diagram of the present invention.
Embodiment
Enter fluidized-bed 3 through preliminary broken fine coal from coal conveyor 2, vaporized chemical oxygen, or the gas mixture of oxygen and water vapour, or the gas mixture of oxygen and carbonic acid gas is delivered to fluidized-bed 3 through gasification agent inlet nozzle 1, after tentatively gasifying in fluidized-bed 3 inside, the raw gas that contains the fine particle coal dust enters slag air flow bed 5 by the outlet pipe 4 of fluidized-bed 3, with the oxygen or oxygen and the water vapour that add by vaporized chemical nozzle 7, or oxygen carries out the high-temperature gasification reaction with the gas mixture of carbonic acid gas, reacted molten slag flows into dreg removing system 6 naturally by the bottom of slag air flow bed 5, is solidified the back by water cooling and discharges.Reacted high-temperature gas is after the top of slag air flow bed 5 is by the low temperature coal gas cooling of quench gas inlet 8, and the outlet pipe 9 by slag air flow bed 5 leaves vapourizing furnace.
