Coal water slurry gasification intelligent adjusting system

Abstract

The invention relates to the technical field of coal water slurry adjustment, and discloses a coal water slurry gasification intelligent adjusting system, which comprises a first detection module, a second detection module and a third detection module, wherein the first detection module, the second detection module and the third detection module are each provided with an output end and a feedback input end, the first detection module outputs a first measured value a1, the second detection module outputs a second measured value a2, the first detection module, the second detection module and the third detection module are all connected with a comparison module, the comparison module comprises a comparator, the output end of the comparator is connected with a controller, an actuator and a controlled object, and the comparison module is connected with a decentralized control module. According to the invention, the condition that a single cylinder or double cylinders of the high-pressure coal slurry pump do not dose within a short time is automatically handled, the automation degree is high, the control accuracy and timeliness are good, the safety is good, and catalyst failure and accidental shutdown accidents of the gasification furnace caused by coal quality changes are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of coal-water slurry adjustment, in particular to an intelligent adjustment system for coal-water slurry gasification. Background technique [0002] Coal-water slurry gasification technology is a popular coal gasification technology at home and abroad, among which AP coal-water slurry gasification technology, multi-nozzle opposed coal-water slurry pressurized gasification technology, Jinhua furnace gasification technology, etc. , which has the characteristics of wide adaptability of coal types, high gasification pressure, large production capacity, high gasification efficiency and less pollution. [0003] At present, the processing capacity of a single coal-water slurry gasification furnace in China has reached 4,000 tons per day. The coal chemical industry presents the characteristics of a single set and a single series. The biggest risk of this feature is the increase in the number of startups and shutdown...
