Appliance for conveying oxidable powder material in fluidization mode

Abstract

The invention discloses a fluidized conveying device for easily oxidizable powder, which belongs to the technical field of conveying equipment. Including warehouse pump upward fluidized conveying system, nitrogen recovery system, nitrogen gas supply system, nitrogen balance system. Adopting the dynamic pressure fluidized dense-phase conveying form with the warehouse pump upwards, the resistance loss of the conveying system is reduced, the vibration of the conveying pipeline is reduced, and the nitrogen consumption is low; the nitrogen is recovered through the compressor unit, which solves the gas volume balance in the conveying process Problem: The use of localized devices greatly reduces the investment cost of equipment while ensuring the advanced nature of the process and the reliability of the equipment.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment, in particular to a fluidized conveying device for easily oxidizable powder. Background technique [0002] Nitrogen protection is required for pneumatic conveying of easily oxidizable powders. Commonly used conveying methods include rotary valve conveying, sending tank pulse conveying and pressure conveying. Rotary valve transportation generally uses imported equipment, although the performance is good, but the cost required is quite expensive; the sending tank pulse conveying device can be used for medium and small conveying volumes and medium and short distances, but it is not suitable for large Conveying volume and long-distance conveying projects; the material and gas mixing degree of the pressure feeding device is relatively low, generally below 10kg material / kg gas, the gas consumption is large, the energy consumption is also high, and large separation and dust removal equipment ...

Problems solved by technology

Rotary valve transportation generally uses imported equipment, although the performance is good, but the cost required is quite expensive; the sending tank pulse conveying device can be used for medium and small conveying volumes and medium and short distances, but it is not suitable for large Conveying volume and long-distance transportation projects; the mixing degree of material and gas in the pressure feeding device is relatively low, generally below 10kg material / kg gas, the gas consumption is large, the energy consumption is also high, and large separation and dust removal equipment are required

Coupled with the difficult problem of nitrogen recovery and gas volume balance in the system, there is still no ideal equipment for pneumatic conveying of easily oxidizable powders.
