Full-blast cooled coal gas generator

Abstract

The invention relates to a coal gas generator, and especially relates to a full-blast cooled coal gas generator. The lower-segment coal gas outlet of a double-section coal gas generation furnace is connected with a cyclone dust collector and the coal gas inlet of a lower-segment coal gas heat exchanger, the coal gas outlets of the lower-segment coal gas heat exchanger are connected with the coal gas inlets of an electric light oil catching device, the coal gas outlet of the electric light oil catching device is connected with a coal gas pressurizing fan and the coal gas inlet of an end cold heat exchanger, and the cold wind inlet of the end cold heat exchanger is connected with an axial flow fan; the lower part of the double-segment coal gas generation furnace is provided with a coal gas generation furnace bottom water seal; the wind gas inlet tube of the coal gas generation furnace bottom water seal is connected with the water phenol water steam outlet of a phenol water evaporator, a steam collection bag is connected with the steam inlet of the phenol water evaporator, and the water jacket of the double-segment coal gas generation furnace is connected with the steam collection bag. The coal gas generator has the advantages of coal gas heat recycle, improvement of the content of hydrogen contained in the coal gas, coal gas combustion value improvement, coal consumption reduction, no phenol water discharge, furthest pollution reduction and the like.

Description

technical field [0001] The invention relates to a gas generator, in particular to an all-air-cooled gas generator. Background technique [0002] The gasifiers used in industrial production can be divided into single-stage gasifiers and double-stage gasifiers according to their structure, and can be divided into hot gasifiers and cold gasifiers according to the gas outlet temperature. The gas cooling process of the existing cold gas generator is completed by the double standpipe and the washing tower behind the single-stage gas generator through water washing and cooling, while the double-stage gas generator is completed by the air cooler and the rear The intercooler is used to complete the cooling process. The problems of these two methods are that on the one hand, a large amount of phenol water is produced in the production, causing environmental pollution; on the other hand, a large amount of heat energy brought by the exported gas is wasted; Increased investment, on the ...
