First, the low-pressure dilute phase pneumatic conveying system is mainly used for the transportation of powder materials in the medium and short distance (10-260 meters), and the specific gravity of the material does not exceed 2.0.
1. It is used for conveying cement in the warehouse or in the warehouse.
2. For the conveyance of the raw kiln head kiln
3. Homogenization system applied to cement storage
4. It is applied to the collection of fly ash in the dust collector of a thermal power plant.
5. Limestone transportation in boiler desulfurization system of thermal power plant
6. Conveying of other powdery materials
1. Simple structure and reliable operation
The injection device of the low-pressure pneumatic conveying pump uses a uniquely designed nozzle to form a high-speed jet, uniformly mixes the material and the conveying gas, and sends the material into the conveying pipe. The pneumatic pressure difference is used to make the material along the pipeline to the receiving destination. The overall structure is simple. Only the Roots fan is a rotating part, so the operation is extremely reliable. According to the feeding method, it can be divided into material seal pump and jet pump.
Due to the continuous conveying of powder and the use of a dilute phase design, it shows that the conveying is more stable, and there is basically no blocking management phenomenon itself. ?
Ontology control only needs “start-up” and “stop-down” operation. Because the process system of the continuous transfer pump is simple, the logic relationship of the configured control system is also simple.
4, small wear and long service life
Due to the continuous transportation, the flow velocity in the pipe is low and constant, so the wear is small, and the service life of the entire system equipment and pipeline is long.
5, convenient and flexible layout
The continuous pump can be arranged horizontally, vertically, and obliquely according to the specific conditions of the system, which meets the ever-changing layout requirements of the project.
6. Fully sealed and pollution-free transportation, meeting the quality requirements of the materials delivered in one fell swoop and in the project
Due to the low positive pressure and full-sealed conveyance, foreign substances cannot enter the tube, so it will not cause any change in the properties of the required materials.
7, the quality of the gas source is not high
Because it adopts the form of continuous conveyance and coupled with the use of roots fans for conveying power gas sources, power gas sources generally do not need to set up a purification system, and only have certain requirements for gas volume and pressure. Independent gas sources or commonly used in engineering Compressed gas station (centralized gas source).
8.High system reliability
The low-pressure pneumatic continuous conveying system composed of a low-pressure jet pump has reliability that cannot be achieved by any other pneumatic conveying equipment. This is because:
● Roots fans are generally used in low-pressure continuous conveying systems. The high reliability of roots fans determines the reliability of the system.
● The pneumatic conveying system is composed of a jet pump. Generally, the number and types of equipment are small, making the whole system simple and reliable.
● Continuous conveying pressure is stable without any impact load.
● The device itself is simple, there is no frequent action of the valve in the conventional pneumatic conveying process, and the failure rate of the device is greatly reduced.
9, economical and reasonable, low cost, low system operating costs
The low-pressure continuous pneumatic conveying system composed of a low-pressure jet pump, due to the above characteristics, also has the characteristics of low cost and excellent operating indicators. Therefore, the superiority of this system: not only reflects its investment savings when the project is launched, but also that it will continue to reflect lower operation and maintenance costs in the future operation and use!
Roots blower: The model is determined by the user's site.
The low-pressure pneumatic conveying pump can choose a material-sealed pump or a jet pump according to the actual situation of the user.
