Embodiment 1

[0033] Such as figure 1 As shown, a kind of fluidized pyrolysis device for sludge powder of the present embodiment comprises:

[0034] Fluidized reactor 1, the fluidized reactor 1 is used for anaerobic fluidized heating of the sludge powder to obtain carbon powder; the upper end of the fluidized reactor 1 is provided with a discharge port 13; the fluidized reactor 1 is provided with The partition 11 and the baffle 12, the partition 11 and the baffle 12 are parallel to each other and vertically arranged below the discharge port 13, a second gap is left between the upper end of the partition 11 and the upper wall of the fluidized reactor 1. A gap 111, a second gap 112 is left between its lower end and the bottom wall of the fluidized reactor 1, and a third gap 121 is left between the lower end of the baffle plate 12 and the bottom wall of the fluidized reactor 1;

[0035] Heat preservation chamber 8, heat preservation chamber 8 is wrapped in the outside of fluidized reactor 1; ...

Embodiment 2

[0047] This embodiment provides a method for fluidized pyrolysis of sludge using the fluidized pyrolysis device in Example 1, using a fluidized fan to convert the sludge powder with a moisture content of 10%-20% in the fluidized reactor into Fluidized state, and then the fluidized sludge powder is pyrolyzed by a heater to obtain carbon powder.

[0048]The fluidized pyrolysis of sludge powder is carried out in a nitrogen environment; while the sludge powder is fluidized and pyrolyzed, a water vapor gasification agent is added to the sludge powder, so that the sludge powder and the water vapor gasification agent are evenly mixed, and the sewage The fluidized pyrolysis temperature of mud powder is 350°C-550°C.

[0049] The working process of the sludge fluidized pyrolysis device in this embodiment is as follows: the sludge powder pulverized by a pulverizer is sent to the fluidized reactor, and then the nitrogen generating device is turned on to fill the entire fluidized reactor w...

Abstract

The invention relates to a fluidized pyrolysis device and method for sludge powder. The fluidized pyrolysis device comprises a fluidized reactor, a heater and a fluidized blower, wherein the fluidized reactor is used for oxygen-free fluidized heating of sludge powder to obtain powdered carbon, and a discharge opening is formed in the upper end of the fluidized reactor; the heater is arranged at the bottom of the fluidized reactor and used for providing heat for fluidized heating of sludge powder; the fluidized blower is connected with the fluidized reactor by an air intake pipeline. As the fluidized reactor, the fluidized blower and the heater are arranged, fluidized heating of sludge powder can be realized, the carbonization time is short and the carbonization effect is good.
