Full-automatic cleaning method of pure oxygen combustor and cleaning control device of pure oxygen combustor

Abstract

The invention provides a full-automatic cleaning method of a pure oxygen combustor and a cleaning control device of the pure oxygen combustor. The full-automatic cleaning method comprises the following steps of turning on ignition of the combustor, starting a high-temperature mode, starting a gun cleaning mode, starting a fuel closing mode, starting combustor cleaning, and starting combustor restart mode. According to the cleaning process of the pure oxygen combustor, switching between cleaning and running is effectively realized through a control system; an alarm step is set to improve the safety; the temperature of a melting furnace is sensed through a temperature sensor; a flame detector monitor the flame state, thus accurately realizing the gun cleaning process in the high-temperature environment and facilitating manual operation; oxygen flow can be changed through an adjusting mechanism, so that the oxygen flow can completely oxidize impurities on a nozzle of the combustor; the oxidation effect of pure oxygen can quickly clean impurities blocked on the combustor, so that the gun cleaning free of fluctuation when the temperature of the melting furnace is reached can be realized, and the gun cleaning keeps continuing. The full-automatic cleaning method of the pure oxygen combustor and the cleaning control device of the pure oxygen combustor has the advantages that the combustor cleaning time is shortened, the combustor cleaning intensity is reduced, and the service life of the combustor is prolonged.

Description

technical field [0001] The invention relates to a pure oxygen burner for metal smelting, in particular to a fully automatic cleaning method for a pure oxygen burner and a cleaning control device thereof. Background technique [0002] During the use of the existing metal smelting burner, the splashed metal raw materials and volatilized raw materials condense on the burner nozzle, causing the combustion flame to deform, and the deformed flame is easy to damage the refractory material of the furnace, and even burns out, resulting in difficult temperature control or uneven distribution. All, the existing operation method is to stop production and take out the burner, and remove the attachment by force, which has many disadvantages such as damaging the burner nozzle and causing the nozzle to deform. The advantages of online cleaning of pure oxygen burners are obvious, including saving time and effort, no need to stop production, no need to cool down, and no large fluctuations in ...
