Pipeline is an important part of pneumatic conveying system and how to keep the pipeline unobstructed?

Pipeline is an important part of the pneumatic conveying system, the proportion in the whole system is also relatively heavy, the pipeline is also the most prone to problems in the whole system, so in the choice of pipeline, which specification of pipeline is the most economical to use in the pneumatic system? This paper analyzes this problem.

In the pneumatic conveying system, for a given material conveying capacity and conveying distance, there is a wide range of pipe diameter specifications, conveying methods and supply pressure to choose which specification of pipe diameter and supply pressure is the most economical, it is necessary to comprehensively consider the construction cost and operating cost of the factory, and the operating cost is mainly caused by energy consumption.

.

By comparison, it can be seen that compared with low-pressure dilute phase transmission, high-pressure dense phase transmission speed is low energy consumption, so the operation cost is low. The pipe diameter used for dense phase transmission is small, and the dust removal equipment is also small, but the sending device (sending tank) is relatively low-pressure rotary valve is more expensive, so the construction cost of the two methods needs to be considered comprehensively.

For conveying materials, there are many choices of pneumatic conveying forms. The common pneumatic conveying forms in engineering are dilute phase conveying and dense phase conveying. Knowing the applicable occasions and energy consumption of dilute phase and dense phase conveying is the premise of reasonable selection of conveying forms and reduction of conveying costs.

Select the appropriate pipe diameter and supply pressure to make the system most economical.

Dust collector is an important component of pneumatic conveying, dust collector once the failure will affect the normal conveying work of the system, usually under the circumstances of pneumatic conveying system dust collector will appear what fault:

1) The running resistance of the dust collector is large;

2) The pulse valve of the dust collector does not work;

3) The poppet valve of the dust collector does not work;

4) The filter bag of the dust collector is damaged.
