Problems solved by technology

[0003] The preparation of black phosphorus is relatively difficult, and the initial high temperature and high pressure conditions are harsh, so it is difficult to produce on a large scale in industry
At present, red phosphorus is mostly converted into black phosphorus by high-pressure method or high-energy ball milling method, but the temperature and pressure are not easy to control, the energy consumption is high, the success rate of synthesizing black phosphorus is low, and the prepared black phosphorus is easily oxidized. Black phosphorus can only be prepared intermittently, and it is difficult to conduct large-scale application research and development and commercialization

Abstract

The invention discloses industrial continuous production equipment for black phosphorus. The equipment includes a heat-resistant screw conversion reactor, a charging pipe, a discharging pipe, a propeller blade, a motor and a heating device. The charging pipe is arranged on one end of the heat-resistant screw conversion reactor. The discharging pipe is arranged below the other end. The propeller blade in the heat-resistant screw conversion reactor is mounting on a rotating shaft. The two ends of the rotating shaft are connected to the heat-resistant screw conversion reactor through shaft sleeves. The motor is arranged on one of the heat-resistant screw conversion reactor and connected to the rotating shaft. The heating device is arranged outside the heat-resistant screw conversion reactor and the charging pipe. The outside of the heat-resistant screw conversion reactor is wrapped in the heating device. The heat-resistant screw conversion reactor includes multiple heating areas. An inertgas input pipe is arranged on the discharging pipe. According to the invention, the production process flow is optimized, the production cost is low, the operation is simple and safe, the automationdegree is high, and continuous production can be carried out under atmospheric pressure.

Description

technical field [0001] The invention relates to the technical field of black phosphorus preparation, in particular to an industrial continuous production equipment and method for black phosphorus. Background technique [0002] Black phosphorus is a black crystal with metallic luster. It has the weakest reactivity among allotropes of phosphorus. It will not ignite in air, so black phosphorus is difficult to prepare. It is generally prepared by heating white phosphorus under high pressure. . Black phosphorus is similar to graphite in appearance, performance and structure. It is black, flaky, and conductive, and the link atoms are in the shape of wrinkled sheets. The phonons, photons and electrons in the layered black phosphorus structure exhibit a high degree of anisotropy, which has great potential application value in electronic thin film and infrared optoelectronics technology. [0003] The preparation of black phosphorus is relatively difficult, and the initial high temp...
