Phosphorus steam dust-moving device capable of realizing high purity phosphorus recovery

Abstract

The invention relates to a phosphorus steam dust-moving device and a working method thereof. The dust-moving device comprises a cylindrical barrel, a first flange connecting opening, a second flange connecting opening, a cylindrical filter screen, a driving mechanism, a gas ejector pipe, a wool yarn plate, a conical barrel, a blanking seal valve, a storage cavity, a discharging seal valve, a heater, a nitrogen intake pipe, an air exhaust pipe, a nitrogen intake valve, and an air exhaust valve, wherein the first flange connecting opening is formed in the top end of the cylindrical barrel and used for inputting phosphorus steam; the second flange connecting opening is formed in the side wall of the cylindrical barrel and used for outputting phosphorus steam; the cylindrical filter screen is arranged in the cylindrical barrel; the driving mechanism drives the cylindrical filter screen to rotate; the gas ejector pipe is used for ejecting nitrogen to the inner wall of the cylindrical filter screen to remove dust; the wool yarn plate is used for brushing dust away from the cylindrical filter screen; the inverted cone-shaped conical barrel is connected with the lower end of the cylindrical barrel; the blanking seal valve is arranged at the lower end of the conical barrel; the storage cavity is formed at the bottom of the first blanking seal valve; the discharging seal valve is arranged at the bottom of the storage cavity; the heater is arranged in the storage cavity; the nitrogen intake pipe and the air exhaust pipe are arranged on the storage cavity; the nitrogen intake valve and the air exhaust valve are respectively arranged on the nitrogen intake pipe and the air exhaust pipe and can be opened and closed at the same time.

Description

[0001] This application is a divisional application, the application number of the original application: 201210222666.2, the name of the invention: phosphorus steam dust removal device and its working method, and the application date: June 29, 2012. technical field [0002] The invention relates to the technical field of dust removal equipment, in particular to a phosphorus steam dust removal device and its working method. Background technique [0003] The production of yellow phosphorus is a high energy-consuming industry. The production of 1 ton of yellow phosphorus consumes at least 14,000 kWh of electricity and 1.6 tons of carbon. China's current annual production capacity is 800,000 tons. A large amount of phosphorus steam, phosphorus furnace tail gas and high temperature slag will be produced in the process of yellow phosphorus production. Similarly, industries such as steelmaking, aluminum smelting, and copper smelting also have a large amount of high-temperature slag...
