There are two types of mine drainage: self-flow drainage and lift-up drainage.
The flat-flow self-flowing drainage is economical and reliable, and the water drains the water to the ground. The section of the ditch is inverted trapezoid, the effective area depends on the flow of water, generally 0.05~0.15m 2 , the longitudinal slope of the roadway requires 3‰～5‰, and the flow rate of water in the ditch is 0.4～0.6m/s.
The lift-up drain is used to drain the pump water to the ground. It is divided into fixed and mobile. The pump house is a fixed type of drainage. When digging the shaft and the inclined shaft, the water pump is suspended on the special steel wire rope and moved along with the excavation.
Hygienic Type Air Handling Unit
Hygienic type Modular Air Handling Unit is used for the clean room in medicine field. Its Air Conditioning system and equipment must apply special device to meet the requirement;
Characteristics.
1.Low Air Leakage Ratio,High Mechanical Strength,Smooth Internal Surface
The frame adopts patented air leakage proof design, embedded groove making foam materials connect both internal and external panels tightly. The foam material is high density polyurethane to make sure the strength of the panel.
2.High Efficient Sterilization
The internal panel of the casing, condensing drainage tray and coil frame are all made of stainless steel.The heat exchanger is made of hydrophilic aluminum fan or copper fin to prevent bacteria. Stainless tilt big drainage tray design make sure the internal of the unit does not remain water and breed the bacteria.
3.Advanced Internal Equipment
The Air handling unit uses electrode and dry steam to humidify, avoiding the humidified circumstance to keep from the breeding of bacteria.
