This invention discloses an integrated device and method for a solid-state storage tank-heat exchanger with built-in phase change, belonging to the field of low-temperature phase change energy storage. The invention arranges heat exchange components in the solid carbon dioxide phase change region within the storage tank body to reduce external heat exchange thermal resistance and improve phase change heat exchange efficiency. During the energy storage stage, liquid carbon dioxide is atomized or jetted through a solid generation injection component, partially becoming gaseous and partially solid, with the carbon dioxide stored in a solid state within a sealed space. During the energy release stage, liquid carbon dioxide is injected into the storage tank body and mixes with solid carbon dioxide to form a slurry. The inlets and outlets of the energy storage and energy release stages are staggered to form different intake areas, improving multiphase mixing and intake stability.

This invention discloses a multivariate collaborative optimization system for industrial circulating water flow for freezing protection of liquid alkali storage tanks, relating to the field of liquid alkali storage tank freezing technology. First, it collects thermal flow infrared images of the liquid alkali storage tank surface and pipe nodes, flow sensor data, and environmental temperature and humidity parameters to construct a multivariate dynamic feature matrix. Then, it extracts freezing sensitivity indicators for each key node to construct a topological map of thermally vulnerable areas. By performing time-series clustering of node flow velocity fluctuations, a freezing conduction probability weight map is generated. Next, the weight map is embedded into the circulating water network optimization objective function, and an improved particle swarm optimization algorithm is used to output the target flow rate of each branch. Based on this, the variable frequency operation parameters of the circulating pump are calculated to drive the hydraulic system adjustment. When the freezing critical value approaches, a micro-circulation heat exchange mode is automatically triggered. This invention can achieve accurate prediction and proactive response to freezing risks, improving the safety and energy efficiency of liquid alkali storage tank operation in winter.
