[0002] Sodium sulfide is an inorganic compound with the chemical formula Na2S. It appears as a white to yellow crystal or powder that is highly hygroscopic and gradually oxidizes in air. Sodium sulfide has a wide range of industrial applications. Its primary use in the manufacture of sulphur dyes is one of its earliest and most important applications. In the dyeing and printing industry, sodium sulfide is often used as a dyeing aid to dissolve sulphur dyes. It is also used in the dehairing process in the tanning industry and as a paper steaming agent in the papermaking industry. In the textile industry, sodium sulfide can be used as a mordant to help dyes penetrate fibers better.

[0003] When sodium sulfate is produced, an electric furnace needs to be heated. Since the heating temperature needs to be different during the reaction and the thickening process, a temperature control component is required to adjust the temperature according to the requirements during the reaction. However, when the temperature control device fails or needs maintenance, the temperature control device is usually fixedly installed on the outside of the electric furnace, so it is necessary to stop the machine for maintenance and replacement, thereby reducing production efficiency. At the same time, the existing production of sodium sulfate is mostly completed in an electric furnace, but the charging port of the electric furnace is located at a high position, making it inconvenient for workers to add materials to it. In response to the above problems, the inventors proposed a special electric furnace for producing sodium sulfide to solve the above problems. Utility Model Content
