Abstract

The pressurized and closed dry coal powder conveyer with several discharge branches includes normal pressure coal portions bin; connected variable pressure bin with gas inlet connected to the nitrogen cylinder, coal powder outlet connected to pressurizing bin and gas outlet connected with filter and the pressurizing bin; pressurizing bin with gas inlet connected to the nitrogen cylinder and coal powder outlet connected to the powder distributor; and powder distributor with lower end connected to nitrogen pipeline and outlet with set shunt branch pipeline. The present invention has powder buffer connected to the pressurizing bin and no mechanical rotating part, and is suitable for closed conveying of high pressure powder. Installing the powder distributor realizes the homogeneous multiple branch conveying with one locking bin system in high overall stability and homogeneous distribution.

Description

technical field [0001] The invention belongs to the technical field of dense-phase conveying of powder materials, and in particular relates to a dry coal powder pressurized dense-phase conveying device for multi-branch discharge. technical background [0002] Powder pneumatic conveying technology is a method of using gas energy to transport powder materials, which has a history of more than 100 years. Theory and practice have proved that powder pneumatic conveying technology has advantages over mechanical conveying, such as simple equipment, flexible layout, easy dust collection, etc. It has been widely used in electric power, metallurgy, chemical industry, building materials, light industry, food and other industries. Wide range of applications. Generally speaking, the dense-phase powder pneumatic conveying technology has the following advantages compared with the dilute-phase powder pneumatic conveying technology: 1. The solid-gas ratio of conveying is large: the amount o...
