Problems solved by technology

The pipeline resistance of the two compressed air channels is different, which will cause the two channels of gas distribution to be unbalanced and difficult to control, which increases the complexity of the system and reduces its safety and reliability.
In addition, the above-mentioned dust removal device cannot re

Abstract

Provided are a foam dust suppression system and a foam dust suppression method for mine excavation. The foam dust suppression system comprises a control device, a foam generating device and a foam sprinkling device. The foam generating device comprises a foam generator and a foaming agent liquid storage pot. The foam generator is respectively connected with a compressed air pipeline of a mine shaft, a clear water pipeline of the mine shaft and the foam sprinkling device. The control device is installed on the compressed air pipeline and the clear water pipeline and used for controlling opening and closing of the compressed air pipeline and the clear water pipeline. The foaming agent liquid storage pot is arranged on the clear water pipeline between the control device and the foam generator and is communicated with the clear water pipeline through a material sucking device. The foam dust suppression method comprises the steps of starting control, foam forming and foam sprinkling. The foam dust suppression system is small in volume, simple in operation, even in foam output and capable of working continuously, stably and reliably and being flexibly applied to a mine excavation working face or a transferring point and other narrow spaces.

Description

technical field [0001] The invention relates to a foam dust suppression system in the field of dust prevention and control, in particular to a foam dust suppression system and a foam dust suppression method suitable for controlling dust disasters in places with narrow spaces such as mine excavation working faces, transfer points and tunnels. Background technique [0002] In the process of mining, a large amount of dust will be produced, and the mining operation is the main process of dust production. The dust production accounts for more than 80% of the total dust, which seriously endangers the physical and mental health of workers and the safe production of enterprises. Taking the coal mine industry as an example, according to incomplete statistics from the Ministry of Health, there are currently as many as 350,000 coal mine pneumoconiosis patients nationwide, and the detection rate of pneumoconiosis is as high as 7.2%, and the number of cases is increasing at a rate of more...
