An Intelligent Control System for Mist and Dust Removal in Stockyards

Abstract

The present invention proposes an intelligent control system for spraying and dedusting of the stockyard, which includes a transportation track for transporting coal to the coal pile area. module, concentration overrun alarm module, intelligent control module and automatic spraying module; the data monitoring terminal of the data monitoring module is connected with the data monitoring terminal of the intelligent control module, and the spraying control terminal of the intelligent control module is connected with the spraying terminal of the automatic spraying module. The control terminal is connected, and the alarm terminal of the intelligent control module is connected with the alarm terminal of the concentration over-limit alarm module; the intelligent control module controls the work of its automatic spraying module according to the monitoring data monitored by the data monitoring module, and sends out an alarm through the concentration over-limit alarm module , to achieve large-scale dust reduction and ensure the dust suppression effect. The present invention considers the influence of wind speed and direction on the dust raising in the coal yard, and at the same time, according to factors such as wind speed and direction, dust concentration, etc., the sprinkler head is centrally controlled to realize precise dust reduction, and realize economical dust reduction on the basis of improving the effect of dust suppression and dust reduction. dust reduction.

Description

technical field [0001] The invention relates to the technical field of dust environmental pollution prevention and control, in particular to an intelligent control system for stockyard spray dust removal. Background technique [0002] my country's coal resources are relatively abundant. For a long time, coal resources have accounted for more than 60% of my country's energy consumption, so coal occupies an important position in my country's main energy. With the increase of dust production during coal transportation and storage, dust pollution has attracted more and more attention from the society. As a new type of dust suppression technology, the spray dust suppression system has a good effect on large-scale and open-scale dust control and dust reduction. Some coal mine stockyards have also realized the control of the dust monitoring system. Dust pollution mainly comes from coal dust pollution generated by coal mine piles, coal storage areas of power plants, and coal transp...

AI Technical Summary

Problems solved by technology

Dust pollution in coal mine stockyards and coal storage areas of power plants is mainly caused by the blowing of coal powder by wind speed. When the wind speed in the stockyard changes alternately, in order to ensure the effect of dust suppression, the operators will carry out dust control based on experience and actual conditions on site. According to the investigation, the angle of the dust suppression atomizing sprinkler head will also change, but its response speed and dust suppression effect are difficult to be guaranteed.

At present, the operation of the existing coal yard dust suppression system is controlled manually, which has the disadvantages of high consumption of water resources and electric energy, poor timeliness, and low degree of intelligence. It is of great significance to improve and solve the problems of wind speed dust in the yard, low efficiency of manual control of dust removal, and incomplete spraying of water.
