Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of phase change material suspension liquid filtration experiment, specifically relates to a phase change material suspension liquid temperature control filtration device. BACKGROUND

[0002] Renewable energy such as solar energy and wind energy has the characteristics of intermittent supply, and its natural fluctuation is inconsistent with the continuity of energy supply, resulting in mismatch between supply and demand. Therefore, in order to effectively utilize renewable energy, it is necessary to adopt cost-effective and large-scale energy storage methods, which can absorb excess energy during off-peak electricity consumption periods and supply stored energy during peak electricity consumption periods. There are various energy storage methods, and phase change material is one of the most suitable materials for effectively storing renewable energy heat. Phase change material (PCM-Phase Change Material) refers to a kind of material that exchanges heat with the outside world by absorbing or releasing heat during the transformation of material state (solid, liquid and gas), so as to achieve the goal of latent heat energy storage.

[0003] In order to understand the characteristics of phase change material in energy storage, it is necessary to prepare phase change material through related experiments, and filtration is involved in the preparation process. Filtration is a physical separation technology, which is widely used in the fields of chemical experiments, industrial production and environmental protection. Based on the filtering effect of coarse and fine screens, solid particles and liquid in the mixture are separated, so that the solid and liquid in the mixture can be separated and extracted. Filtration has the characteristics of simplicity, economy and high efficiency, and the separation effect of solid with large particle size is good. The general experimental filtration process is to take a filter paper and pad it on the sand core filter, then clamp the filtration bottle and the filter with a clamp, open the vacuum pump, then pour the liquid to be filtered, and wait for the filtration process to end. However, the above filtration is carried out at room temperature, which will be affected by the change of indoor temperature and the freezing point of phase change material suspension liquid. During the filtration process, the freezing point of phase change material suspension liquid may be very high, so it may freeze in advance during filtration, resulting in the interruption of filtration.
