Centralized control diffusing ignition device and ignition method thereof

Abstract

The invention discloses a centralized control diffusing ignition device and an ignition method thereof in the field of diffusing towers. The centralized control diffusing ignition device comprises a plurality of diffusing towers, wherein igniters are arranged on the diffusing towers, the igniters are controlled by a control system, the diffusing towers are provided with pressure sub-meters and steam valves in a one-to-one correspondence manner, and the pressure sub-meters are connected with a pressure main meter; a water seal is arranged between each diffusing tower and the corresponding pressure sub-meter, the pressure main meter is in data connection with a control system, a temperature sensor is arranged at the tops of the diffusing towers, the temperature sensor is in data connection with the control system, and the control system controls on-off of the steam valves; and the control system detects whether ignition succeeds or not through the temperature sensor, and when ignition fails or the pressure is smaller than the lower limit value of the set pressure, the control system controls the water seals to be closed and opens the steam valves for purging, it is ensured that flames are extinguished while coal gas in the diffusing towers is blown away, the use safety of the diffusing towers can be ensured, and the multiple diffusing towers can be controlled in a centralized manner.

Description

Technical field[0001]The invention relates to an ignition device and a method thereof.Background technique[0002]In the production process of converter steelmaking in the iron and steel industry, a large amount of combustible organic gases will be emitted, which will pollute the environment and have a serious impact on people's health. Therefore, domestic iron and steel enterprises have installed a diffuser ignition device on the top of the diffuser tower of their converter steelmaking. This device generally uses a high-voltage generator for high-voltage discharge, and uses an arc to ignite pure gas, and then a flame of pure gas is used to ignite the discharged gas. Because the environment at the top of the tower is very harsh, a large amount of dust accumulates on the porcelain bottle of the high-voltage electrode, and rain and other reasons cause the insulation of the high-voltage discharge electrode to drop, and the electrode cannot discharge and arc, which leads to ignition failu...
