Positive Pressure Dilute Phase Continuous Jet Conveying Pump For Dust Conveying Equipment

Description

Positive pressure dilute phase pneumatic conveying system
1. Product Introduction
The positive pressure dilute phase pneumatic conveying system can be achieved by two types of air sources for pipeline dust-free conveying. The air source is provided by Roots blower or air compressor, but for most working conditions, Roots blower is still widely used as the air source. The Roots blower uses a gas pressure of less than 1kg/c ㎡ and adopts a positive pressure (pressure delivery type) to push materials through the entire conveying line at a higher speed. Therefore, this conveying method is called a low-pressure high-speed system, which has a high gas material ratio.
The Roots blower is used as the power source, and air or nitrogen is used as the conveying medium. The material is dispersed and suspended in the pipeline at a high speed, with a conveying distance of hundreds of meters. At the beginning of the system, there is an acceleration of about 10m/s, and at the end, it can reach a high speed of 30m/s. Therefore, the airflow speed is relatively high. The initial pressure of the transmission pipeline is generally lower than 0.06Mpa, while the end pressure is basically close to atmospheric pressure.
The characteristics of positive pressure dilute phase conveying: it can transport materials from a low point to multiple points; Large conveying capacity, suitable for short or medium distance conveying.
2. Application Area
The PJP type positive pressure dilute phase pneumatic conveying jet pump is a low-pressure, dilute phase, and continuous pneumatic conveying equipment suitable for situations where the conveying volume is not large and the conveying distance is medium. It can be widely used in industries such as building materials, chemicals, electricity, grain, metallurgy, casting, etc. The conveying materials include cement, raw materials, fly ash, hydrated lime, slag powder, steel slag powder, coal powder, aluminum oxide powder, phosphorus powder, pyrophyllite powder, and organic silicon powder.
3. Main features of the product
PJP type positive pressure dilute phase pneumatic conveying jet pump is a pneumatic conveying device with automatic control, which has a compact structure, reliable performance, simple maintenance, long service life, and low investment cost. The moving parts are only materials and air. When connected to the dust removal device, its fully enclosed system design can provide a completely dust-free working environment.
When the PJP jet pump pneumatic conveying system is installed at the bottom of the silo to transport materials using the pressure of the materials in the silo, changes in the height of the materials in the silo will cause corresponding changes in the material conveying speed. Therefore, the conveying capacity of the materials depends on the height of the materials in the silo .
When the PJP jet pump pneumatic conveying system is equipped with a locking device, the conveying capacity of the material depends on the locking capacity of the locking device.
Based on extensive engineering practice experience, most dilute phase continuous pneumatic conveying processes are as follows:
