Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] See figure 1 A storage yard environmental protection monitoring and sprinkler dust reduction pre-control system shown includes a dust concentration real-time detection device 1, an anemometer 2 and a temperature and humidity sensor 3, and the dust concentration real-time detection device 1, anemometer 2 and temperature The humidity sensors 3 are respectively connected with the detection control computer 4, and the detection control computer 4 is connected with the PLC controller 5, and is connected with the sprinkling and spraying equipment 6 through the PLC controller 5. Therefore, using the detection system composed of the dust concentration real-time detection device 1, the anemometer 2 and the temperature and humidity sensor 3, after obtaining various detection signals, the detection data is transmitted to the detection control computer 4 by ...

Abstract

The invention discloses a stockyard environmental-friendly monitoring and sprinkling dust reduction pre-control system. A stockyard environmental-friendly monitoring and sprinkling dust reduction pre-control apparatus comprises a dust concentration real-time detection device, a wind speed anemoscope and a humiture sensor which are respectively connected with a detection control computer, and the detection control computer is connected with a PLC and is connected with a sprinkling spray device. According to the invention, after various detection signals are obtained through various detection systems, the detection signals are transmitted to the detection control computer, a control judgment value d of the sprinkling spray device is calculated by use of a dust concentration influence factor analysis algorithm, and the judgment value d is compared to experience thresholds D1 and D2 (D1 is a control lower limit value and D2 is a control upper limit value) which are determined through numerous data statistical analysis methods so that whether the sprinkling spray device sprinkles can be controlled. The problems are solved that neither accurate monitoring nor real-time performance and accuracy of detection results under various environment conditions can be realized in the prior arts.

Description

technical field [0001] The invention relates to a detection and control device, in particular to a device for detecting the dust concentration of a stockyard and controlling the operation of dust reduction and dust removal equipment. Background technique [0002] During the transshipment of coal and ore at the port, there are two main operating procedures: one is unloading, stacking, retrieving, and loading; the other is unloading, stacking, retrieving, and loading. Dust pollution in coal and ore yards is mainly caused by coal and ore powder being blown by the wind, and is mainly affected by weather factors such as wind speed, wind direction, temperature, humidity, rain and snow. Sprinkling and spraying dust reduction is the main means of dust removal and dust reduction. Sprinkling and dust removal operations include a variety of working modes, mainly including: regular and quantitative watering (normal watering): through the preparation of PLC programs, the watering amount ...
