Dilute Phase Pneumatic Conveying System

Middle and low pressure dilute pneumatic conveying system

Working principle

The blower arranged in the conveying system starting point will be higher than the atmospheric pressure of the positive pressure air inlet feeder device, adding the material from the hopper, under the action of gravity into feeder quantitative feeding, feed gas via pipeline to the end of the separator or in a storage chamber. After material gas separation, air is filtered into the atmosphere.

System characteristics

This system is a Roots blower for air, rotary feeder for feeding device. Continuous pressure material a pneumatic conveying system. The system has the characteristics of low pressure, short conveying distance and reliable transportation. Suitable for distributed transmission from one to many places. The role of the material in the drying and grading. As the system is under pressure, so even in the pipe system is composed of a gap, the outside air or rain will not invade, the material is easy to discharge from the discharge port.

Pneumatic conveying general introduction and transportable material

Pneumatic conveying means using air (gas) as transportation power and convey dispersed solid material in the pipe.

● Variable arrangement of the pipe makes the production craft process more reasonable

● The system is sealed and lead to few flying dust, it benefit for environment protection

● Few movement parts, convenient maintenance, automatic control can be realized easily

● High efficiency of transportation reduce the cost of packing, loading and unloading

● Make the material avoid being damped, polluted, damaged and mixed with other material, the quality of conveying is assured

● Multiple operation process can be realized meanwhile for the conveying, such as mixture, crush, grade, dryness cooling, and dust collection

● Send the material from couple place to one place and from one place to couple place, realize far distance operation

● For the material with erratic chemical character, can adopt inertia gas conveying

Production equipment

Exquisite production technology, perfect quality assurance system, provide quality guarantee for product performance.

Three kinds of transport modes for pneumatic conveying system

A. Suspended flow

Material conveying speed is higher than suspension speed. Material flow in a pipe. The concentration ratio is small, the transmission method is suitable for the short distance transportation of the low pressure and dilute phase.

B. Group flow

Material conveying speed is approximately equal to the suspension flow velocity, the material in the pipe into the group state of movement. The concentration ratio is moderate, which is suitable for medium pressure long distance transportation.

C. Plug flow

Material conveying speed is lower than that of the suspension velocity. Material in the pipe is pulsed by valves, pneumatically cut into plug-like segments, and relies on the static pressure difference between slugs as the driving force to move forward. High concentration ratio. This delivery mode is suitable for high pressure and dense phase long distance transport at low speed.

Conveying material

Available pneumatic conveying of powder and granular material variety, each kind of the material property of pneumatic conveying device of appropriateness and efficiency have great influence; Therefore, the performance of the material must be measured before selecting the conveying device.
