Intelligent control system for spray dust removal of storage yard

Abstract

The invention provides an intelligent control system for spray dust removal of a storage yard, and the system comprises a transportation track for transporting coal to a coal pile area; the coal pile area is arranged on one side or two sides of the transportation track, and a data monitoring module, a concentration over-limit alarm module, an intelligent control module and an automatic spraying module are arranged in the coal pile area; a data monitoring end of the data monitoring module is connected with a data monitoring end of the intelligent control module, a spraying control end of the intelligent control module is connected with a spraying control end of the automatic spraying module, and an alarm end of the intelligent control module is connected with an alarm end of the concentration over-limit alarm module; the intelligent control module controls the automatic spraying module to work according to monitoring data monitored by the data monitoring module, and gives an alarm through the concentration over-limit alarm module, so that large-range dust falling is realized, and the dust suppression effect is ensured. According to the invention, the influence of wind speed and wind direction on dust raising in the coal storage yard is considered, the spray header is controlled in a centralized manner according to factors such as wind speed and wind direction, dust concentration and the like, precise dust fall is realized, and economical dust fall is realized on the basis of improving dust suppression and dust fall effects.

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.
