A fully automatic cleaning method for a pure oxygen burner and its cleaning control device

Abstract

The present invention provides a full-automatic cleaning method for a pure oxygen combustor and a cleaning control device thereof. Said method comprises: a combustor conducting an ignition starting step, a high-temperature mode starting step, a gun cleaning mode starting step, a fuel shutdown mode starting step, a combustor cleaning starting step, and a combustor restarting mode starting step. During the cleaning process of a pure oxygen combustor, switching between cleaning and running is effectively realized by means of a control system, an alarm step is set to improve the safety, the temperature of a melting furnace is sensed by means of a temperature sensor, and a flame detector monitors the flame state, so as to precisely implement a gun cleaning process in a high-temperature environment and facilitate manual operation by an operator; an oxygen flow is changed by means of an adjusting mechanism, so that the oxygen flow can completely oxidize impurities on a nozzle of the combustor; and the oxidation of pure oxygen can quickly clean up impurities blocked on the combustor, achieving gun cleaning without fluctuation in the melting furnace temperature and gun cleaning without stopping production. The invention shortens the time of combustor cleaning, reduces the intensity of combustor cleaning, and prolongs the service life of the combustor.

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 ...
