A kind of operation method of thermal phosphorus production process

Abstract

The invention discloses an operation method of a thermal phosphorus production process, which includes the following steps: (1) firstly use an electrode holder and a hydraulic lifting system to basically adjust and balance the position of the electrodes, and check the current of each electrode according to the ammeter and voltmeter; , voltage size is observed; (2) carry out comprehensive analysis and processing according to the observation result of step (1) and other process parameters of the phosphorus furnace, so that the position of each electrode, ammeter and voltmeter display numbers are basically consistent; (3) according to the furnace condition and process parameters, timely lift the electrodes, and repeat step (2) to coordinate and balance each electrode after lifting the active electrodes. The operation method of the thermal phosphorus production process provided by the present invention overcomes the defects of the traditional operation method, and optimizes the overall process parameters and operation indicators of the large and medium-sized multi-electrode phosphorus production electric furnace using three phases or more, so as to achieve energy saving and environmental protection , High-quality and high-yield, reduce the production cost of the enterprise, and prolong the service life of the phosphorus furnace.

Description

technical field [0001] The invention relates to the technical field of yellow phosphorus production, in particular to an operation method of a thermal phosphorus production process. Background technique [0002] The production process of thermal yellow phosphorus is between metallurgy and chemical industry. Both the basic principle, experience and the operation and control of electric furnace production equipment have distinctive characteristics. , full and excellent" play a very important role. [0003] The control of electrodes and process parameters is particularly important in the production process, and its adjustment effect directly affects the energy consumption of yellow phosphorus products and the quality of yellow phosphorus. During production, there is an electrode molten pool under each electrode in the yellow phosphorus electric furnace. At this time, if the electrode ends are in a horizontal plane (that is, the electrode position is balanced), all the electrod...
