A few days ago, the reporter learned from the Provincial Intellectual Property Office that the “Device and Method for Continuously Stopping (Opening) Electrolysis Cells for Aluminum Electrolysis Series†developed by Henan Zhongfu Industrial Co., Ltd. and other units won the 12th China Patent Prize Award. The invention and promotion have great significance for the energy saving and emission reduction of the electrolytic aluminum industry. According to the relevant person in charge of the Provincial Intellectual Property Office, this is also the fifth Chinese patent prize awarded by the province so far.
In the traditional aluminum electrolysis production process, when the electrolytic cell is being repaired, the entire system must be powered off. Frequent power outages not only affect the production, but also have a great impact on the power grid and reduce the life of the electrolytic cell and the power supply equipment. At the same time, the greenhouse gas produced is 6,000 times that of normal production, making the aluminum industry a well-reviewed "big dye vat." According to experts' calculations, after the "aluminum electrolysis series of devices and methods for continuously shutting down (opening) electrolyzers" has been widely used, an example of an aluminum-electric one-manufacturer company with a production capacity of 250,000 tons can reduce electrolysis aluminum series power outages 140 times a year. Increase the production of 2,800 tons of primary aluminum, save more than 30 million kilowatt-hours, and generate more than 50 million kilowatt-hours of electricity for the self-produced power plant. The annual production value can increase by more than 80 million yuan, and the direct economic benefit can be more than 20 million yuan. It can also increase power generation and electrolytic aluminum production equipment. Lifespan, reducing greenhouse gas emissions and hazardous waste.
