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.

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 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.
