The application belongs to the technical field of cloud computing and artificial intelligence, and is used to solve the problem that the prior art cannot perceive the anchor point domination relationship within a batch and dynamically constrain the batch boundary accordingly. Specifically, the application is a cloud server data security management system, which comprises a task acquisition module, a conflict analysis module, a conflict relationship construction module, a grouping management module and an execution control module. The application constructs the potential domination strength based on a sliding window and the output sensitivity based on the model sensitivity and the permission level for each task, calculates the conflict coefficient for batch constraint, so that when the input feature value of a task exceeds three times of the quartile range of its own historical distribution, the conflict coefficient between the task and the high sensitivity task automatically exceeds the dynamic threshold, thereby the task is split into different batch groups. The task pair with the conflict coefficient exceeding the threshold is marked as a conflict and prohibited from being in the same batch, and the low permission task cannot enter the same batch as the high sensitivity task.

[Object] A high value-added material having excellent alkali resistance is developed by effectively utilizing waste material discharged from coal-fired power plants and copper slag discharged from copper smelters. [Solution] With regard to a non-crystalline inorganic composition containing silica (SiO2), iron oxide (Fe2O3), alumina (Al2O3), and calcium oxide (CaO) as main components, when i) a total content of silica, alumina, and calcium oxide is set to be 50% by mass or more and 75% by mass or less; ii) a content of iron oxide is set to be 26% by mass or more and less than 40% by mass; and iii) iron oxide is derived from a non-crystalline raw material, an inorganic composition that can be melt-spun and has excellent alkali resistance is obtained. In this inorganic composition, most of the raw materials can be derived from coal ash and copper slag.

The present invention provides an iron and steel smelting method. The method comprises performing a catalytic dehydrogenation reaction on propane, wherein electricity is used to provide energy for the catalytic dehydrogenation reaction; separating the product of the catalytic dehydrogenation reaction to obtain a mixed gas containing hydrogen, methane, and ethane, and ethylene and propylene; and mixing the mixed gas containing hydrogen, methane, and ethane with water and / or CO2 as a catalytic conversion raw material, and producing synthesis gas by means of a catalytic conversion reaction, the synthesis gas being used for iron smelting, and electricity being used to provide energy for the catalytic conversion reaction. According to the present invention, under the circumstances that propane cannot be completely converted in some reaction conditions, catalytic dehydrogenation of propane is combined with steam cracking, and unconverted propane is prepared into methane, ethane, etc. by means of steam cracking; synthesis gas is further obtained by means of reforming and component adjustment, and the synthesis gas is a good raw material for direct reduction of iron.

This invention belongs to the field of waste gas treatment technology, specifically disclosing a flare gas incineration treatment system for EVA production. The system includes a daily gas buffer tank and an emergency gas buffer tank, each connected in series with a liquid separator, a water seal tank, and a cooler. The gas outlets of the two coolers are connected to an incinerator, and the flue gas outlet of the incinerator is connected in series with an induced draft fan and a chimney. Addressing the safety risks, such as explosions, posed by direct combustion of flare gas generated during EVA production, this invention achieves safe, efficient, and compliant emissions of flare gas by classifying and collecting the flare gas, separating it into liquids, applying a water seal, pre-treating it with cooling, and precisely monitoring key parameters, combined with efficient incineration in an incinerator. This solves the problem that direct combustion of flare gas containing hydrocarbons such as ethylene, vinyl acetate, and organic solvents generated during EVA production can easily lead to explosions or flameout accidents due to gas composition imbalance.

The invention relates to a multi-bacteria system for synthesizing 2-methylbutyric acid / alcohol. The multi-bacteria system comprises an upstream strain and a downstream strain, the upstream strain can be used for converting a substrate glucose into 2-butanone acid through pyruvic acid or converting the substrate glucose into 3-methyl-2-oxyvaleric acid through 2-butanone acid; the downstream strain can be used for converting the 2-butanone acid into the 2-methylbutyric acid / alcohol through the 3-methyl-2-oxyvaleric acid, or converting the 3-methyl-2-oxyvaleric acid into the 2-methylbutyric acid / alcohol. An upstream strain and a downstream strain in the multi-bacteria system are obtained by modifying escherichia coli, the metabolic pressure of a host is smaller, the functional specificity is higher, and more substances and energy in cells are used for synthesizing intermediate products and target products. Under the condition of the same substrate concentration, the yield of the 2-methylbutyric acid / alcohol synthesized by the multi-bacteria system is obviously higher than that of the 2-methylbutyric acid / alcohol synthesized by pure culture, which indicates that the multi-bacteria system has higher synthesis efficiency and lower cost in the 2-methylbutyric acid / alcohol.
