Abstract

The invention belongs to the technical field of dust removal, and particularly relates to an efficient and intelligent dust removal system for a mine. The system comprises a control device, a foam dust-removal device, a fan dust-removal device and a dust sensor; the control device is connected with the foam dust-removal device, the fan dust-removal device and the dust sensor; and the control device comprises a first intrinsically-safe power supply, a first alternating-current power supply, a second alternating-current power supply, a second intrinsically-safe power supply, a dust concentrationsensor, a dust sensor switch, a power switch, a toggle button and an auxiliary solenoid valve button. According to the system, intelligent dust removal can be realized, manual control is not required, the intelligent dust removal system starts equipment intelligently according to the dust concentration of the working surface, the dust removal efficiency is high, energy consumption and utilizationare optimized, a safe and comfortable production environment is provided, the driving working surface of the system is dust-free, noiseless and pollution-free, and green mining is realized. The system is applied to dust removal.

Description

technical field [0001] The invention belongs to the technical field of dust removal, and in particular relates to a high-efficiency intelligent dust removal system for mines. Background technique [0002] As the degree of mechanization of coal mine excavation in our country is getting higher and higher, the footage of the excavation face is getting faster and faster. But what follows is that the generation of dust is also increasing, seriously endangering the health of employees, and even causing coal dust explosions. In particular, the dust concentration of fully mechanized excavation in rock roadways can reach 1000-3000㎎ / m³. In order to solve the dust problem in the tunneling face, in addition to the spray dust suppression that comes with the roadheader, products such as foam dust removal series equipment and fan dust removal series equipment have been derived, but none of them can solve practical problems well. The efficiency of foam dust removal is low, and the noise o...
