Negative pressure pneumatic ash removal system

Dilute phase negative pressure delivery technology description

 

Dilute phase negative pressure pneumatic conveying generally uses a Roots fan, centrifugal fan or vortex pump as the power source. The pipeline and the vacuum upper hopper are evacuated to a certain vacuum state, so that the air inlet is formed into powder, granules and gas under the action of atmospheric pressure The two-phase flow is fed into the vacuum loading hopper through the conveying pipe. Gas-solid separation is performed through a vacuum loading hopper.

 

Main features of dilute phase negative pressure pneumatic conveying:

 

Multi-point feeding and multi-point discharging can be implemented; continuous or gap transportation is possible; good environmental performance, no dust leakage; equipment use cost and maintenance cost are relatively low; transportation pressure and transportation distance are subject to certain restrictions. The typical process flow diagram is as follows.
