All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1:

referring to fig. 1 to 4, the powder fission mixing system provided in this embodiment includes a reaction chamber 1, a pipe 2, a spray assembly, a filter screen assembly 4, and an air suction mechanism, where:

the reaction chamber 1 is provided with a feed inlet for injecting powder and a discharge outlet for guiding out reactants, and the reaction chamber 1 is further provided with a solution inlet and other components, which are the same as the prior art, so detailed description thereof will not be repeated here. When the method is specifically used, powder and solution are injected into the reaction bin 1, so that the powder and the solution are contacted in the reaction bin 1 to generate fission reaction, and then target elements are extracted from the powder (i.e. industrial waste residues).

The pipeline 2 is connected with the reaction chamber 1 and is communicated with the interior of the reaction chamber 1. The pipe 2 is used for discharging the flue gas generated in the reaction chamber 1, because the flue gas is generated in the reaction process in the reaction chamber 1. Optionally, in this embodiment, the materials of the pipe 2 and the reaction chamber 1 are determined according to the powder and the solution, and the connection manner between the pipe 2 and the reaction chamber 1 is a fixed connection.

The spray assembly, the screen assembly 4 and the suction mechanism are all mounted to the pipe 2.

The spraying component is used for spraying water towards the flue gas entering the pipeline 2, so that the flue gas entering the pipeline 2 is subjected to water filtration, and particles in the flue gas are settled into an aqueous solution. And meanwhile, the spray water is mixed with high-temperature water vapor, so that the temperature of the water vapor is reduced, and the water vapor is condensed again into water which falls into the reaction bin 1. The filter screen assembly 4 is used for filtering the flue gas flowing through the pipeline 2, so as to perform secondary filtration on the flue gas discharged through the pipeline 2, and further reduce the flue gas flowing through the pipeline 2Discharge outIs a content of harmful elements in the flue gas.

The air suction mechanism can extract the flue gas generated in the reaction bin 1, so that the speed of the flue gas exhaust in the reaction bin 1 is accelerated, high air pressure is not easy to form in the reaction bin 1, and the amount of the flue gas directly exhausted from the feed inlet is reduced, in other words, the air suction mechanism can enable most of the flue gas generated in the reaction bin 1 to be exhausted from the pipeline 2, and the flue gas is filtered by the spraying component and the filter screen component 4 in the exhausting process. Of course, a small amount of unfiltered flue gas will also be discharged from the above-mentioned feed inlet, but the amount of discharge is greatly reduced, so that there is less pollution to the environment. In addition, this embodiment implicitly includes a power source for powering the inhalation mechanism.

Optionally, the reaction chamber 1 in this embodiment has a chamber top 11 with a conical shell shape, the conical tip of the chamber top 11 faces upward, and a through hole is formed in the middle of the chamber top 11, the pipe 2 is connected to the chamber top 11 and is located outside the reaction chamber 1, and a region where the pipe 2 is installed and assembled by spraying is vertically downward, and the pipe 2 is communicated with the inside of the reaction chamber 1 through the through hole. Since the spray assembly in this embodiment is installed in the pipe 2, the water sprayed from the spray assembly falls directly into the reaction chamber 1 under the action of gravity. Although water beads are also adhered to the inner wall of the pipe 2 and the inner wall of the top 11, the part of the pipe 2 is vertically arranged and the top 11 is in a conical shell shape, so that the adhered water beads can smoothly flow into the solution in the reaction chamber 1 under the action of gravity.

In this way, the water drops attached to the inner wall of the pipe 2 directly flow into the diversion gap 7 along the wall under the action of gravity, and since the main body of the diversion gap 7 and the inner cavity of the reaction chamber 1 are separated by the shroud plate 6, the influence of the high temperature and air pressure in the reaction chamber 1 on the internal environment of the diversion gap 7 is small, so that the water flow entering the diversion gap 7 can flow from one end to the other end more smoothly, the water drops attached to the inner wall of the pipe 2 can flow back into the inner cavity of the reaction chamber 1 more smoothly, and the water drops are prevented from being dried before flowing into the reaction chamber 1 to form solid scale (in particular, smoke condensate) on the inner wall of the pipe 2 or the inner wall of the chamber top 11. In addition, the diversion crack 7 can also play a role in water isolation, so that water flow or water drops are not easy to flow to the inner surface of the shroud plate 6, and the inner surface of the shroud plate 6 can be kept dry as much as possible.

Optionally, the air suction mechanism in this embodiment is an exhaust fan 5, which can pump the flue gas in the reaction chamber 1 to the pipeline 2 for discharge when the air suction mechanism is in power-on operation, so as to accelerate the flue gas discharge speed in the reaction chamber 1. The spray assembly is installed at a position close to the inlet of the pipeline 2, so that water sprayed by the spray assembly can flow back into the reaction chamber 1 more smoothly. The filter screen assembly 4 is mounted between the suction fan 5 and the spray assembly. The pipe 2 in this embodiment is an L-shaped bent pipe, which includes a horizontal section and a vertical section, the vertical section is connected with the roof 11 of the reaction chamber 1 (axially vertical), and the spray assembly is installed in the vertical section, so that water sprayed by the spray assembly can flow into the reaction chamber 1 more smoothly. The horizontal section faces sideways, and the suction fan 5 and the screen assembly 4 are mounted in the horizontal section.

Alternatively, the spray assembly in this embodiment includes a spray head 3, the spray head 3 is mounted on the wall of the pipe 2 and connected to a water source (or a water pump) through a water pipe, so that water is sprayed toward the inside of the pipe 2 by the spray head 3, and the spray head 3 sprays water in a radial direction of the pipe 2. Because the flow direction of the flue gas is the axial direction of the pipeline 2, the water sprayed along the radial direction of the pipeline 2 can better filter the flue gas flowing in the pipeline 2. The quantity of this shower nozzle 3 is a plurality of, and a plurality of shower nozzle 3 evenly distributed in the circumference of pipeline 2 to a plurality of shower nozzle 3 is crisscross distributed in the axial of pipeline 2, like this, will form the water curtain that the multilayer was strained to the flue gas on the route that the flue gas circulated, thereby it is better to the water filtration effect of flue gas. The filter screen assembly 4 comprises a mounting frame and a filter screen arranged in the mounting frame, wherein the mounting frame is arranged in a pipeline, the filter screen is a metal screen plate, and filter holes are formed in the filter screen.

Optionally, in this embodiment, a stirring blade 8 is further rotatably installed in the reaction chamber 1, and a driving motor 9 is installed at the bottom of the reaction chamber 1, and the driving motor 9 is electrically connected to a power supply. The rotating shaft of the driving motor 9 penetrates through the bottom of the reaction chamber 1 and is connected with the stirring blade 8 so as to drive the stirring blade 8 to rotate in the reaction chamber 1, and then the reactants in the reaction chamber 1 are stirred, so that the powder and the solution are more uniformly mixed, and the fission reaction is better carried out to extract the target elements. Of course, a sealing ring is installed between the rotating shaft of the motor and the bottom of the reaction chamber 1 to prevent leakage. The stirring blade 8 and the driving motor 9 constitute a stirring unit for stirring the contents (i.e., the solution and the powder) in the reaction chamber 1. The top of the reaction chamber 1 is also connected with a support frame 10, the support frame 10 enables the reaction chamber 1 to be supported away from the ground, and the driving motor 9 is positioned in the support frame 10.
