Pneumatic conveyer with nitrogen recycling function

Abstract

A pneumatic conveyer with a nitrogen recycling function is characterized in that the bottom of a buffer chamber is connected with a pneumatic conveying unit via an adjustable rotary valve, the pneumatic conveying unit is connected with a storage chamber via a pipeline, the storage chamber is connected with a storage chamber dust collector via a pipeline, the storage chamber dust collector is connected with a constant pressure gas reservoir via a pipeline, the constant pressure gas reservoir is connected with a gas compressor via a pipeline, the gas compressor is connected with a gas dryer viaa pipeline, the gas dryer is connected with a nitrogen maker via a pipeline, the nitrogen maker is connected with a gas buffer tank via a pipeline, and the gas buffer tank is connected with the pneumatic conveying unit via a pipeline to form a circulation loop. The pneumatic conveyer has the advantages that conveying can be achieved for fragile materials and organic materials having high requirement on moisture, conveying process safety is greatly improved, and the content of water in materials is effectively controlled; nitrogen circulation is provided for the conveying process, nitrogen is produced with low oxygen content, processing time of the nitrogen maker is effectively extended, and conveying cost is reduced.

Description

technical field [0001] The invention relates to a pneumatic conveying device, in particular to a pneumatic conveying device for nitrogen recycling. Background technique [0002] Pneumatic conveying has the advantages of large conveying capacity, long conveying distance, and high conveying speed. Combined with the characteristics of crushing rate and high-speed movement in the conveying process, it is not suitable for organic solid particle materials. The existing technology uses nitrogen as the conveying medium. Although it solves the problem of conveying organic solid particle materials, the nitrogen used for conveying is entrained by the material or polluted by water and oxygen during the conveying process, so it cannot be recycled and directly discharged into the atmosphere, causing energy waste on the ground, and even form an explosive mixture with the dust of the broken organic solid particle material, which poses a safety risk. If the recycling of nitrogen can be real...
