Problems solved by technology
[0009] To sum up, in the conventional powder material delivery system, during the storage and delivery process, the activity of the material is prone to decrease, and it does not have the ability to restore its activity
For some cohesive materials, it is difficult to achieve quantitative, continuous and stable conveying
For special materials such as dioxin calcium-based blockers, it is far from meeting their transportation requirements

Embodiment Construction
[0042] The invention solves many problems existing in the existing conventional material conveying system. Through the fluidized bed activation device, combined with the vertical disc feeder, the conveying system can realize quantitative, continuous and stable conveying of materials. Especially for special materials such as dioxin calcium-based blockers that are easy to absorb moisture and are easy to bond, it has the ability to restore activity. The following description is based on powdered dioxin calcium-based blockers as an example.
[0043] The conveying system of the present invention comprises: a silo 1, a vertical disc feeder 2 and a thermal instrument 5; wherein the silo 1 has a bottom discharge port 102; the vertical disc feeder 2 has a discharge end 203 and the feed end 201 connected to the bottom discharge port 102.
[0044]It also includes a fluidized bed activation device 3 and a conveying air preheating device 4; wherein the fluidized bed activation device 3 h...

The invention discloses a powdered substance conveying system with an activation function. The powdered substance conveying system comprises a material storehouse, wherein a material discharging opening in the bottom of the material storehouse is connected with the material feeding end of a vertical type disk feeder; the material discharging end of the vertical type disk feeder is connected with a material inlet of a fluidized bed activation device; an activation device outlet connected to a feeding point is formed in the top of the fluidized bed activation device; a bed material feeding device is arranged on the middle part of the fluidized bed activation device and is positioned below the material inlet; an air distribution device is arranged on the lower part of the fluidized bed activation device and is connected with a conveying air outlet of a conveying air preheating device through an air inlet; a slag discharging device is arranged at the bottom of the fluidized bed activation device. The invention also discloses a conveying method for powdered substances.
Description
technical field [0001] The invention relates to a material conveying system, in particular to a conveying system for powders with an activation function. [0002] The invention also relates to a method for conveying powders using the above-mentioned conveying system. Background technique [0003] Incineration treatment of solid waste such as domestic garbage and hazardous waste has the advantages of complete harmlessness, high reduction, and high heat recovery and utilization rate. It is one of the technologies that best embodies the three principles of waste treatment. It has been widely used in developed countries and regions. Since the end of the 1990s, waste incineration technology has also developed rapidly in my country, but it cannot be ignored that the incineration method of domestic waste has also brought about secondary pollution, of which dioxins are the most important a class of pollutants. [0004] Dioxin calcium-based blocking technology is an efficient contr...
