Abstract

método de controle de material e sistema para um dispositivo de limpeza de gás de combustão. o método compreende: obter uma velocidade de equilíbrio básica em tempo real, a velocidade de equilíbrio básica sendo a velocidade operacional de um alimentador de rolo do dessorvedor quando uma descarga total de um dessorvedor por unidade de tempo é igual a uma descarga total de um adsorvedor; obter uma velocidade alvo de acordo com uma diferença entre um nível de material médio efetivo do adsorvedor e um nível de material médio alvo do adsorvedor e a velocidade de equilíbrio básica; se for detectado que a amplitude de flutuação da velocidade de operação do alimentador de rolo do adsorvedor em uma primeira extensão de tempo predefinida é maior que uma amplitude predefinida; controlar o alimentador de rolo do dessorvedor para operar na velocidade alvo; se a diferença entre o nível de material médio efetivo e o nível de material médio alvo do adsorvedor permanece em uma faixa de diferença predefinida por um segundo período de tempo predefinido; controlar o alimentador de rolo do dessorvedor para operar na velocidade alvo.material and system control method for a flue gas cleaning device. The method comprises: obtaining a real-time basic equilibrium velocity, the basic equilibrium velocity being the operating speed of a desorbent roller feeder when a total discharge of one desorbent per unit time is equal to a total discharge of an adsorber ; obtain a target velocity according to a difference between an effective average adsorber material level and an average adsorber target material level and the basic equilibrium velocity; if the adsorber roller feeder operating speed fluctuation amplitude is detected over a preset first time span is greater than a preset amplitude; control the desorbent roll feeder to operate at the target speed; whether the difference between the mean effective material level and the adsorber target average material level remains within a predefined difference range for a second predefined time period; Control the desorbent roll feeder to operate at the target speed.
