This invention provides an energy-saving blast furnace gas temperature regulation device, applied at the blast furnace gas outlet. It includes a gravity dust collector, a radiator, a dust collection bag, and a turbine. The gravity dust collector is connected at one end to the blast furnace gas outlet and at the other end to the radiator, used for preliminary removal of large particulate impurities from the blast furnace gas. The radiator is connected at one end to the gravity dust collector and at the other end to the dust collection bag, used to control the temperature of the blast furnace gas and prevent damage to the dust collection bag. The dust collection bag is connected at one end to the radiator and at the other end to the turbine, used to remove impurities from the blast furnace gas, completing the purification process. The turbine, connected to the dust collection bag, converts the pressure and thermal energy of the blast furnace gas into rotational mechanical energy to drive a generator. This invention effectively regulates the temperature of the blast furnace gas, simultaneously treating the gas and enabling its recycling.

The invention discloses a process and a method for preparing a nano material. Specifically, lithium iron phosphate, composite sodium iron phosphate and calcium carbonate are efficiently prepared by adopting a sol-gel method and a precipitation method respectively. When the lithium iron phosphate and the composite sodium iron phosphate are prepared, the reaction process is controllable by regulating and controlling the oscillation condition, the reaction temperature, the pH value and the retention time, and a target product is obtained after the gel is calcined. When calcium carbonate is prepared, nucleation and crystallization are enhanced by controlling the flow rates of a precursor, a precipitator and a surfactant and combining oscillation. According to the method, mixed mass transfer is enhanced by means of periodic oscillatory flow, local supersaturation and concentration gradient are inhibited, reactant deposition and channel blockage are reduced, continuous and stable production is guaranteed, meanwhile, the use amount and cost of a surfactant are reduced, and accurate regulation and control over the particle size, morphology and distribution of the material are achieved. Compared with a traditional process, the preparation period is greatly shortened, the product purity and the reaction efficiency are improved, and the method is suitable for industrial continuous production and has remarkable economic benefits and social benefits.

This utility model discloses an air conditioner, including a casing assembly, an air guide assembly, and a heat exchange and air supply assembly. The casing assembly includes a main casing assembly and a front panel assembly, which is connected to the front end of the main casing assembly.
