Title:
MATERIAL CONTROL METHOD AND SYSTEM FOR FLUE GAS PURIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/205693
Kind Code:
A1
Abstract:
A material control method and system for a flue gas purification device. The method comprises: obtaining a basic equilibrium speed in real time (101), the basic equilibrium speed being the operating speed of a roller feeder of a desorption tower (200) when the total discharge of the desorption tower (200) per unit time is equal to the total discharge of an adsorption tower (100); obtaining a target speed in real time according to the difference between the actual average material level of the adsorption tower (100) and a target average material level and the basic equilibrium speed (102); if the operating speed of the roller feeder of the adsorption tower (100) is detected to change within a range wider than a preset range during a preset first period of time, controlling the roller feeder of the desorption tower (200) to operate at the basic equilibrium speed (103); and if the difference between the actual average material level of the adsorption tower (100) and the target average material level is detected to remain within a preset difference range for a preset second period of time, controlling the roller feeder of the desorption tower (200) to operate at a target speed (104). The material control method for the flue gas purification device can ensure that the operation of the material is quickly adjusted to a relatively balanced state when the actual material level of the adsorption tower (100) changes abruptly, and thus has better applicability.
