Abstract

The invention provides a powder dispensing device and method. Fluidizing air, pulse air and pressurized air are connected to a dispensing tank in the device, the fluidizing air is used for fluidizingpowder, the pressurized air is used for pushing the powder to move downwards to enter the action range of the fluidizing air, and the pulse air is used for damaging powder blocks and powder arches which are bonded in the dispensing tank. The system is provided with a powder mass and flow monitoring system, and the mass and flow of powder in a feed delivery pipe is detected and determined so as toadjust the air quantity of each pipeline. Compared with a traditional dispensing tank conveying system, the bridges and agglomerations of bonding powder can be damaged, and the continuous stable feedof the bonding powder is realized.

Description

technical field [0001] The invention relates to the fields of energy engineering and chemical industry, in particular to a material sending device and method suitable for powder. Background technique [0002] Thermal power generation is the energy pillar of our country, but coal will release a large amount of toxic and harmful elements during the combustion process in the furnace, among which trace heavy metal elements are very harmful to human beings and the environment. The literature (Yin Lianqing, Guan Xinyu. Electric Power Environmental Protection 3 (2005) 31-34) has reported that adding solid adsorbents to capture heavy metals during coal combustion is widely considered to be a very promising technology. The toxic heavy metal vapors released in the coal process undergo physical adsorption and chemical reactions to achieve the solidification of heavy metals, thereby reducing the emission of heavy metals in the coal combustion process. [0003] Kaolin and activated carb...
