Dense phase pneumatic ash conveying system,Its use ed for the
Pneumatic Conveying System:
Introduction:
positive pressure dense phase pneumatic conveying system is simple,
flexible layout, reliable operation, high degree of automation,
system investment, high transmission/gas ratio, low velocity, small
maintenance workload and low operation cost etc. This system
including feeding device, send warehouse pumps, pipes, valves, dust
removal device, bottom gasification device, discharge device, power
source, programmable device, etc.
General Introduction:
The dense phase pneumatic conveying system is applicable to the
conveying of powder material as dry ash, cement, and industrial
chemicals. It is a high efficiency, zero pollution conveying
system, widely used in the material conveying in industry of power
plant, building materials, and chemicals.
Technical Characteristics:
1, High Energy Saving
For the reasonable fluidizing structure, the fluidizing state of
the material is good, and the air consumption is obviously lower
than the same function equipment. After years research and
development, we have improved the fluidizing structure for many
times to improve the working efficiency and lower the energy
consumption.
2, High Material-Air Ratio
If the fluidizing effect is good, air consumption is low, the
material-air ratio will be high. The test has shown that when the
equivalent distance is within 500m, the ratio will reach above 30Kg
(ash)/Kg (air)
3, Low Material Flowing Speed
Because the air consumption is low and the material-air ratio is
high, the material will have shunting movement in the pipe,
achieving dynamic and static pressure conveying. Therefore, the
flowing speed of the material is slow, the abrasion of the valve
and pipeline is low, and the service life of the wearing part is
long.
4, High Adjustment Function
It has primary and secondary inlet air adjusting methods, which
makes the system work under the best air consumption ratio
condition and the best fluidizing state.
5, Unique Unblocking Method
The unblocking system adopts the unique positive pressure back
suction unblocking principle, having the characteristics as low air
consumption and reliable unblocking. It only needs to lead the
material-air mixture going through the unblocking valve and
pipeline to the material hopper or inlet of air flue, do not need
set additional blowing element along the pass, construction is
simple and operation is easy.
