Abstract

The invention belongs to the technical field of coal flow flying dust control and in particular relates to an automatic coal flow dust control spraying method and an automatic coal flow dust control spraying system. The invention discloses the automatic coal flow dust control spraying method which comprises the following steps: S101, mixing starch grafted acrylic polymer, a surfactant and water soas to obtain a coal flow dust control agent; S102, testing the total dust concentration of a coal flow, and further calculating spraying information of the coal flow dust control agent according to the total dust concentration of the coal flow; S103, spraying the coal flow dust control agent according to the spraying information. The invention further provides an automatic coal flow dust controlspraying system. By adopting the automatic coal flow dust control spraying method and the automatic coal flow dust control spraying system provided by the invention, the technical defects that in theprior art a conventional coal flow dust control method is poor in dust control effect, short in effect lasting time and great in time and labor are solved.

Description

technical field [0001] The invention belongs to the technical field of coal flow dust control, and in particular relates to an automatic spraying method and system for coal flow dust suppression. Background technique [0002] Coal flow refers to the coal conveying system. During the transportation of coal on the belt, it is easy to generate dust, resulting in waste of resources and environmental pollution. Dust dynamic coal flow can be divided into advection dust and downflow dust. During the movement of the belt, the air on both sides of the belt will generate traction airflow with the movement of the belt. Due to the viscosity of the gas, there is a velocity gradient between the coal flow on the belt and the traction airflow. Under the action of the coal flow, it will move relative to the coal flow, peel off the coal, and generate a certain amount of dust above the belt, which is advective dust. Falling dust is formed by the combined action of induced airflow and shearin...
