The principle of the positive-pressure dilute phase pneumatic conveying system
The roots vacuum pump is commonly used in the negative-pressure suction type pneumatic conveying system for air supply, air suction system, conveying the negative pressure in the tube forming under atmospheric pressure, air inlet formed material and two phase gas flow into the pipe, under a certain velocity, the suction to the air separation equipment, at the end of the material under the action of gravity and centrifugal force, separated into the bunker, gas by the roots vacuum pump or centrifuge discharge into the atmosphere.
The characteristics of the positive-pressure dilute phase pneumatic conveying system
1, the system pressure below the atmospheric pressure inside, so the material will not leak from the system,environmental protection
2, low pressure, reliable transmission, simple equipment, low investment
3, easy to implement multipoint feeding
4, with big mouth suck material, to avoid the feeding point of the dust float in the sky
5, suitable for short distance transport, generally within 100 m.
