Device for producing yellow phosphorus through microwave method and production technology

Abstract

The invention relates to a device for producing yellow phosphorus through a microwave method and a production technology and belongs to the technical field of preparation of the yellow phosphorus. Thedevice comprises a tank body, a first microwave feed-in assembly and a second microwave feed-in assembly, wherein the first microwave feed-in assembly is located at the top of the tank body and comprises a plurality of feed-in waveguides and a plurality of microwave reflective sheets; microwaves are fed in the tank body and are focused in a reduction reaction region; meanwhile, interference between the fed-in microwaves is eliminated through the microwave reflective sheets when the microwaves are fed in from the top of the tank body; the second microwave feed-in assembly is located at the bottom of the tank body and is provided with a plurality of dielectric waveguides; aluminum oxide ceramic is used as the dielectric waveguides and the microwaves are fed into the reduction reaction region from the bottom of the tank body, so that influences of a material, which intensely absorbs microwave, on the microwaves are overcome; continuous microwave chemical reaction of the reduction reaction region is maintained, so that an environment condition needed by the production of the yellow phosphorus is realized; the device has the characteristics of low energy consumption and low corrosion and the maintenance cost of the tank body is reduced.

Description

technical field [0001] The invention belongs to the technical field of yellow phosphorus preparation, and in particular relates to a device and a production process for producing yellow phosphorus by a microwave method. Background technique [0002] The history of phosphorus production in the world has been more than a century, and the development of phosphorus industry has experienced a development process from small to large. The capacity of a single electric furnace of traditional yellow phosphorus electric furnace has developed from 200kVA to today's single electric furnace with a capacity of 45,000 to 60,000 kVA, the power consumption of the phosphorus industry ranks first in the chemical industry. [0003] At present, my country has developed into the world's largest yellow phosphorus country, with a production capacity of more than 1.2 million tons per year. Elemental phosphorus is the essence of human life. At the same time, phosphorus is also very important in indu...
