Problems solved by technology
This kind of catalyst heating method of the converter has high requirements on the electric furnace, the power of the electric furnace must be large, and the load of the transformer must be sufficient. Because the line current is large, the requirements on the electrical equipment are high. Once the electrical failure occurs, the heating will be blocked and cannot be carried out smoothly. achieve the purpose of driving
And with the gradual cancellation of preferential electricity prices in the chemical fertilizer industry, electricity prices have increased more and more, while oil prices have continued to decline, and the heating costs of converters have continued to rise

The invention discloses an energy-saving temperature rise and test run method for a sulfur-based sulfuric acid production converter. The test run method comprises the following steps: raising the temperature of one section of the converter to 360-380 DEG C by using an electric furnace, closing the electric furnace, and blowing heat of a sulfur burning furnace into the converter for performing temperature rise and test run. The method disclosed by the invention has the advantages that the existing general manner of raising the temperature of the electric furnace for the sulfur-based sulfuric acid production converter is changed into a manner of using the electric furnace at the initial stage of temperature rise and raising the temperature of the converter in a heat accumulation and hot blow manner of the sulfur burning furnace at the tail stage, so that the test run process is simple, efficient, pollution-free, safe and reliable.
Description
technical field [0001] The invention relates to an improvement of a production process for heating up and energy-saving start-up of a sulfur acid converter. [0002] technical background [0003] The temperature of the catalyst in the traditional sulfur acid converter is generally raised by setting up an electric furnace at the entrance of the first section, and using the electric furnace to heat the dry air to raise the temperature of the first section of the converter catalyst to above 430°C. The temperature of the sulfur incinerator is raised by using a diesel burner to raise the temperature of the furnace to above 800°C, and then the blind plate is pumped and the blind plate is sprayed with sulfur to start the operation. This kind of catalyst heating method of the converter has high requirements on the electric furnace, the power of the electric furnace must be large, and the load of the transformer must be sufficient. Because the line current is large, the requirements o...
