Full-fraction coal tar metal filtering and purifying device and method

Abstract

The invention relates to the technical field of full-fraction coal tar metal filtering, and particularly discloses a full-fraction coal tar metal filtering and purifying device and method.The side face of a feeding component is fixedly connected with the inner side of the top of a main body shell, the top of the feeding component is fixedly connected with a feeding pipe, and the feeding component comprises a feeding shell; the top of an inner cavity of the feeding shell is fixedly connected with the bottom of a feeding pipe. According to the full-fraction coal tar metal filtering and purifying device and method, a limiting mechanism is arranged, flowing kinetic energy of coal tar is utilized, dynamic adding of a flocculation demetalization agent is achieved, through linkage of a spiral blade and an impact block, the flow speed and flow of tar are directly associated with the agent adding amount, the larger the impact force of the tar is, namely the larger the flow is, the higher the rotating speed of the spiral blade is, and the higher the agent adding amount is. The impact frequency and force are enhanced, the displacement amount of the limiting sleeve is driven to be increased, more agents are promoted to be released, and agent waste or insufficiency caused by traditional quantitative adding is avoided.
