Port coal dust pollution purification system

Abstract

The port coal dust pollution purification system comprises a dynamic cleaning plate and a static cleaning plate, the dynamic cleaning plate comprises a dust removal vehicle for purification, a first movable dust collection wall and a second movable dust collection wall, and the static cleaning plate comprises an industrial flying dust detector, a wind shielding and dust suppression wall and a flexible dust covering net. The dust removal vehicle for purification is used for cleaning coal dust raising dust or small coal dust piles, the first movable dust collection wall is used for collecting coal dust within the height range of 0-4 m, the second movable dust collection wall is used for collecting coal dust within the height range of 4-10 m, and the industrial raising dust detector is used for detecting the air quality of all detection points of a coal yard. The wind shielding and dust suppression wall is used for reducing coal dust diffusion, and the flexible dust covering net is used for covering the coal pile to prevent coal dust diffusion. According to the port coal dust pollution purification system provided by the invention, purification devices adapted to corresponding working environments are designed in all areas of a coal port, so that the coal dust pollution problems in multiple aspects can be solved.

Description

technical field [0001] The invention relates to the technical field of port pollution prevention, in particular to a port coal dust pollution purification system. Background technique [0002] The fugitive dust generated during loading, unloading and transportation at coal ports will diffuse into the air and become the source of dust pollution in surrounding cities. Over the years, the problem of dust control at coal terminals has plagued local governments and terminal operators for a long time, and it is urgent to solve the problem of dust pollution at coal ports. [0003] There are many factors that affect dust formation in the process of coal transportation and loading, mainly including: coal particle size, water content in coal, loading and unloading process, coal type, wind speed, season, geographical location and so on. The dust removal methods commonly used in coal ports today include closed dust removal and wet dust removal. The closed dust removal is to close the k...

AI Technical Summary

Problems solved by technology

Experience shows that a better spraying device can reduce respirable dust by about 30%, but for the northern coastal ports where fresh water resources are scarce and the winter is cold and frozen, its use is greatly restricted; Pollution and its disposal issues

As a dust-proof binder, water has only a temporary effect, and it must be sprayed repeatedly at regular intervals. Natural meteorological conditions such as strong winds, evaporation, etc., often affect the watering effect; in addition, due to the inability to grasp the optimal amount of watering, the problem of waste of water resources More severe in coal ports;

[0004] These dust removal methods cannot control the dust in various links such as port loading and unloading, transshipment, and storage
