Title:
HIGH-VOLTAGE POWER SOURCE CONTROL METHOD FOR CONVERTER GAS PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/208438
Kind Code:
A1
Abstract:
A high-voltage power source control method for a converter gas purification system, the method belonging to the technical field of converter gas dust removal systems. The method comprises the specific steps of: a stage control method from the starting of the voltage of a high-voltage electric field to starting completion, and a stage control method after the voltage of the electric field undergoes high-voltage breakdown during a starting process of the voltage of the electric field or after the starting is completed. By means of the method, the problem in the prior art of excessive emission caused by severe reduction of the dust removal efficiency due to a high-voltage power source being restricted, after high-voltage breakdown, to operate at a low voltage is solved. According to the high-voltage power source control method, a high electric field voltage can be automatically regulated after high-voltage breakdown, such that an electric field can stably operate, and reaches the maximum electric field voltage under the condition of not suffering from breakdown.
