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 storage yard environmental protection monitoring and sprinkler dust reduction pre-control system, a storage yard environmental protection monitoring and water sprinkling dust reduction pre-control device, including a dust concentration real-time detection device, an wind speed and direction instrument, and a temperature and humidity sensor, which are respectively connected with a detection control computer. connection, the detection control computer is connected to the PLC controller, and is connected to the sprinkling and spraying equipment through the PLC controller. The present invention obtains various detection signals through each detection system, and transmits them to the detection control computer, uses the dust concentration influencing factor analysis algorithm to calculate the control judgment value d for controlling the sprinkler spray device, and compares the judgment value d with a large amount of data The empirical thresholds D1 and D2 determined by the statistical analysis method (D1 is the lower limit of control, D2 is the upper limit of control) are compared to control whether the sprinkler spray equipment sprinkles water. Solve the problem that traditional technology is difficult to achieve accurate monitoring and real-time accuracy of detection results under various environmental conditions.

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 ...
