The utility model discloses a water-free heating radiator with circulating wind power, which comprises a plurality of parallel micro-channel heating pipes, the two ends of each micro-channel heating pipe are respectively provided with a collecting pipe, heat source gas can enter the heating radiator from one collecting pipe, and the heat source gas can enter the heating radiator from the other collecting pipe. After passing through a plurality of micro-channel heating pipes, the heat flows out of the other collecting pipe, and the heat is dissipated into the heating radiator in the process; wherein a plurality of heat dissipation fins are arranged outside the micro-channel heating pipe, and a plurality of air flow channels which are longitudinally through and relatively closed in the transverse direction are formed by the heat dissipation fins; and the fan is arranged, the flow speed of air in the air flow channel is increased through the fan, the heat exchange efficiency is improved, the rotating speed of the fan is adjustable, and therefore the heat exchange rate and the indoor temperature can be adjusted.

The invention relates to a method for synergistically reducing and recovering lithium carbonate from an aluminum-containing waste power battery ternary positive electrode material. The method comprises the following steps: crushing the aluminum-containing ternary positive electrode material, and carrying out sufficient synergistic reduction under the condition that CO2 is introduced by taking aluminum impurities carried by the raw material as a reducing agent; and then carrying out water immersion under the condition of introducing CO2, and evaporating the water immersion liquid to dryness to obtain a lithium carbonate product. The water leaching residue can be used as a raw material of a ternary positive electrode material precursor after alkali leaching and aluminum removal. According to the method, the generation of lithium metaaluminate impurities is effectively inhibited by utilizing the synergistic reduction effect of aluminum and CO2, the subsequent deep impurity removal pressure is relieved, the recovery process cost can be effectively reduced, and the method has good economic benefits and application prospects.

The application provides a single W coated oxide loaded boron fuel and a preparation method. The oxide loaded boron fuel is Bi2O3 / B or V2O5 / B. The surface layer of the single W coated oxide loaded boron fuel is a single W film. The inner layer is B. The middle layer between the W film and B is Bi2O3 particles or V2O5 particles. The application adopts an atomic layer deposition method to deposit a single metal W film on the surface of Bi2O3 / B and V2O5 / B to anchor the Bi2O3 and V2O5 particles, and to prevent the agglomeration and growth of the Bi2O3 and V2O5 particles at high temperatures. The deposition of W in the application makes the ignition of the composite fuel easier, and can increase the heat release of the composite fuel. The preparation method adopted in the application has high control precision, is easy to realize industrialization, and shows a good application prospect in the field of high-energy solid fuel modification.

The invention discloses a method for continuously producing N-nitroso-3-azabicyclo [3.3. 0] octane.
