Construction site flying dust treatment method

Abstract

The invention relates to a construction site raised dust treatment method, which comprises the following steps of: detecting a wind speed value and a PM value in real time by arranging a wind speed detector at any ventilation position in a construction site and arranging a PM detector in an area where raised dust is easy to generate; the PM detector is automatically matched with the pipeline booster pump, the electromagnetic valve and the electric switch which are arranged in the spraying connecting pipe and close to the PM detector, and feeds back a matching signal to the central control unit, and when the actually measured PM value reaches a PM induction value, the central control unit can detect the air speed according to the PM value monitored by the PM detector and the air speed value detected by the air speed detector. According to the method, a pipeline booster pump, an electromagnetic valve and an electric switch which are matched with a PM detector are controlled to work, the spraying water amount, the spraying height and the spraying time are automatically controlled, accurate dust removal of different areas in a construction site is achieved, when the actually measured PM value reaches a PM induction value again, next dust removal is automatically conducted, and the dust removal efficiency is improved. The automation level and the dust falling efficiency of the device are improved, and spraying water is reduced.

Description

technical field [0001] The invention relates to the technical field of dust control, in particular to a method for controlling dust in a construction site. Background technique [0002] Excessive dust on construction sites is more serious. Excessive dust will not only cause physical damage to construction workers, but also to the health and environment of surrounding residents. In order to prevent excessive dust, construction sites usually use spraying methods to reduce dust. [0003] At present, dust control is mainly carried out by manual sprinkling or sprinkler trucks, and the degree of automation is low. Even if the automatic spraying method is adopted, when the construction area is large, it is impossible to accurately control the amount of spraying water and spraying according to the different conditions of dust in each area. The height of the shower is high, resulting in a waste of water resources, and the effect of dust suppression is not good. [0004] To sum up, t...
