Pneumatic conveying equipment, also called pneumatic conveying device, is a wide range of conveying equipment, which can be used for conveying various powdery materials such as electric ash removal, cement homogenization and dumping, biomass power generation, boiler ash removal, and desulfurization system. Air is used as a power source to be transported along the pipeline, and the gas and material are separated at the end of the pipeline by a material-gas separation device, so as to achieve the purpose of transporting materials. This technology has a history of more than 200 years. Because it is a closed conveyor, it has the advantages of dust resistance and environmental protection, so it is widely used in various industries.
The first is the applicability of pneumatic conveying equipment. This is very important. The successful application of a successful powder closed transportation and metering system is successful in applicability, and more than 90% of the failed application cases are failing in applicability. In terms of traditional gas and liquid closed delivery and metering systems, after hundreds of years or even hundreds of years of development and research, the technology and its applicability have become very mature. Almost all gases and liquids can be successfully processed, but powders In this regard, there are only a short period of 30 to 40 years in foreign countries, and it has only been in the past 10 years in China.

Working principle of pneumatic conveying equipment

Principle of pneumatic conveying equipment: This device is a complete set of system equipment that uses compressed air as the power to dry convey solid particles through sealed pipes. The system generally includes five parts: air source, transmitter, pipeline, control and silo. It has the advantages of high conveying capacity, small pipeline wear, long conveying distance, low energy consumption, no pollution and high degree of automation. Is currently the advanced solid particle dry conveying equipment.

Technical Parameters

Designed according to the nature of the conveyed material (particle size, specific gravity, etc.) provided by the user, conveying distance, climbing height, site conditions, productivity, conveying method (continuous or intermittent), etc., and selecting the appropriate equipment is a tailor-made, single design , Small batch, many varieties of non-standard products. According to the different combinations of equipment, pneumatic conveying devices can be generally divided into three basic forms: suction type, compressed type and mixed type.
I. Suction type pneumatic conveying device: The characteristics of this conveying method are:
1. The material can be sucked from several places at the same time and transported to a centralized place.
2. It is suitable for conveying materials with wide stacking area, or installed in low depth.
3. As long as there is an air suction port, the pipe can be easily extended into some narrow places (such as the lower part of the hopper) to suck the material for transportation.
4. During the conveying process, there is no dust flying, the feeding port can be opened, and the feeding and conveying can be performed continuously.
5. Because the pressure of the conveying air stream is lower than the atmospheric pressure, the water is easy to evaporate, so it is easier to convey the material with more moisture than the compressed air type.
2. Compressed pneumatic conveying device: The characteristics of this conveying method are:
1. Dividing the conveying pipe and installing a switching valve can change the conveying route or convey to several places at the same time.
2. Because the pressure of the conveyed air can be increased to the maximum exhaust pressure rated by the fan, it can maintain a certain degree of adaptability even if the conveying conditions are slightly changed, which is suitable for high-concentration and long-distance conveyance.
3. The inside of the entire device is in a positive pressure state, and the materials are easily discharged from the discharge port. The structure of the unloader and dust collector is simple, but the structure of the feeder is more complicated. During transportation, dust is easy to fly.
