Intelligent dust concentration limit setting spray dust settling device, system and method

Abstract

The invention discloses an intelligent dust concentration limit setting spray dust settling device. The device comprises a control unit, a dust concentration sensor, an electromagnetic valve and a sprinkler head, wherein the signal output end of the dust concentration sensor is connected with a signal input end of the control unit; a control signal output end of the control unit is connected with a control signal input end of the electromagnetic valve; and the control unit realizes spray control over the sprinkler head through the switching of the electromagnetic valve. In the device of the invention, the dust concentration limit is manually set; the spraying starts when the dust concentration limit exceeds an upper limit value and stops when the dust concentration limit is less than a lower limit value; and thus the meaningless waste of water resource is prevented, the water logging in roadways is reduced, the working conditions are improved and the health and the safety of mine workers are ensured. In addition, the invention also discloses an intelligent dust concentration limit setting spray dust settling system, so the remote on-line monitoring of the dust concentration can be realized; meanwhile, the invention also discloses an intelligent dust concentration limit setting spray dust settling method.

Description

technical field [0001] The invention relates to the field of mine safety monitoring and monitoring, in particular to an intelligent dust concentration limiting spray dust suppression device, and also relates to an intelligent dust concentration limiting spray dust suppression system and method. Background technique [0002] There are two main aspects of dust hazards: one is the harm to the human body. If the human lungs inhale a large amount of mineral dust for a long time, they may suffer from pneumoconiosis. Pneumoconiosis is currently a serious occupational disease among miners. The 2nd, coal dust explosion hazard, coal dust explosion is one of serious disaster of coal mine, and it seriously threatens mine safety. In recent years, gas and coal dust explosion accidents still occur from time to time, seriously affecting mine safety production and workers' lives. Therefore, it is imminent to do a good job in the comprehensive management of mine dust. [0003] The dust in t...

AI Technical Summary

Problems solved by technology

However, at present, my country's coal mines mainly use conventional sprinkler devices in terms of dust reduction. These sprinkler devices spray regardless of the dust concentration, which seriously wastes water resources and causes excessive water accumulation in the roadway, which brings inconvenience to work.
