Abstract

SISTEMA DE CONTROLE E MÉTODO DE CONTROLE PARA PELETIZADOR. Um sistema de controle e um método de controle para um peletizador (11). O sistema inclui um peletizador (11), um dispositivo de abastecimento de água (21), uma balança de esteira de alimentação (31), um controlador de velocidade de rotação (12), um controlador de ângulo de inclinação (13), um controlador de água (22), um controlador de material (32), e uma unidade de processamento central (5). A unidade de processamento central (5) é configurada para realizar as seguintes etapas: prever taxas de qualificação de pelotas verdes com base em uma velocidade de rotação do peletizador (11), um ângulo de inclinação de um disco de peletização do peletizador (11), uma quantidade de alimentação, uma quantidade de abastecimento de água, um tipo e uma proporção de cada componente em um material misto, uma porcentagem de um agente de ligação no material misto, e um teor de umidade original do material misto, para obter taxas de qualificação previstas das pelotas verdes em uma pluralidade de períodos de previsão; e otimizar, usando um modelo de otimização de rolagem, a velocidade de rotação do peletizador (11), o ângulo de inclinação do disco de peletização do peletizador (11), a quantidade de alimentação, e a quantidade de abastecimento de água com base na taxa de qualificação prevista das pelotas verdes em cada período de previsão e uma taxa de qualificação alvo predefinida das pelotas verdes em cada período de previsão, de modo a controlar, em tempo real, a velocidade de rotação do peletizador (11), o ângulo de inclinação do disco de peletização do peletizador (11), a quantidade de alimentação fornecida ao peletizador (11), e a quantidade de abastecimento de água fornecida ao peletizador (11). Desta forma, uma taxa de qualificação real das pelotas verdes pode atender a um padrão predefinido e, assim, a qualidade de peletização do peletizador (11) pode ser melhorada.CONTROL SYSTEM AND CONTROL METHOD FOR PELLETIZER. A control system and a control method for a pelletizer (11). The system includes a pelletizer (11), a water supply device (21), a feed belt scale (31), a rotation speed controller (12), a tilt angle controller (13), a water controller (22), a material controller (32), and a central processing unit (5). The central processing unit (5) is configured to carry out the following steps: predict qualification rates of green pellets based on a rotational speed of the pelletizer (11), an angle of inclination of a pelletizing disk of the pelletizer (11) , a feed amount, a water supply amount, a type and proportion of each component in a mixed material, a percentage of a binding agent in the mixed material, and an original moisture content of the mixed material, to obtain rates predicted qualification of green pellets in a plurality of forecast periods; and optimizing, using a scroll optimization model, the rotational speed of the pelletizer (11), the angle of inclination of the pelletizing disk of the pelletizer (11), the amount of feed, and the amount of water supply based on the predicted qualification rate of the green pellets in each forecast period and a predefined target qualification rate of the green pellets in each forecast period, in order to control, in real time, the rotation speed of the pelletizer (11), the angle of inclination of the pelletizing disk of the pelletizer (11), the amount of feed supplied to the pelletizer (11), and the amount of water supply supplied to the pelletizer (11). In this way, a real qualification rate of the green pellets can meet a predefined standard and thus the pelletizing quality of the pelletizer (11) can be improved.
