Whether there is too much dust and high gas concentration in the drilling process, how to solve these problems?
The problems of dust removal at the borehole mouth, gas dilution and dust removal in high gas environment are all handed over to Ruilong drilling tools.
new products developed today:Type gas-water linkage wet orifice dust removal device for mine
KCS-18-QS-A type mine gas-water linkage wet orificeDust removal device(hereinafter referred to as the dust removal device) for coal mine drilling hole mouth dust removal, can also be used for high gas environment of gas dilution, dust removal. The dust removal device does not need an external power supply, and the product itself has no power supply equipment and rotating friction parts, so the product is used in a high gas environment and has the characteristics of not being restricted by the use environment. It has the advantages of simple operation and convenient use. It can greatly improve the air environment of the drilling operation site, which is beneficial to the physical and mental health of the operators and improve the work efficiency.
Dust removal device working conditions:
1) Elevation not exceeding1000m；
2) Ambient atmospheric pressure:86kPa~106kPa;
3) Ambient temperature:0℃~ 40℃;
4) Relative humidity:≤95%( 25℃);
5) Methane mixture explosive gas and coal dust are allowed in the conveying gas water.
