Abstract

The invention provides a coal water slurry gasification process system. The coal water slurry gasification process system comprises a gasification unit and a heat recovery unit, wherein the gasification unit comprises a coal gasifier; the heat recovery unit comprises a heat exchanger and a cooling device, wherein the air inlet of the heat exchanger is connected with the first air outlet of the coal gasifier, the air inlet of the cooling device is connected with the air outlet of the heat exchanger, and each of the heat exchanger and the cooling device is provided with a heat exchange pipe; a cooling medium is filled in both the heat exchange pipe of the heat exchanger and the heat exchange pipe of the cooling device and is used for recovering heat carried by synthetic gas flowing through the heat exchanger and the cooling device. By using the coal water slurry gasification process system provided by the invention, the heat in the synthetic gas can be recovered again.

Description

technical field [0001] The invention relates to the technical field of coal gasification, and more specifically relates to a coal-water slurry gasification process system. Background technique [0002] The existing Texaco coal-water slurry gasification technology is a mature coal gasification technology, but there are still various problems, such as: the huge heat energy of the high-temperature syngas cannot be effectively recovered, the water consumption is high, and the chilling interior parts have been exhausted. Damage, short operation period, coal cinders cannot be dried on site, easy to cause secondary pollution during transportation, and the existing coal cinder drying technology has high energy consumption and poor drying effect, and the syngas contains high ash content and high water content. Contents of the invention [0003] The present invention aims to provide a coal-water slurry gasification process system to solve the problem that a large amount of heat ener...
