Description

Technical Field

[0001] The utility model relates to the technical field of heating and cooling related equipment, in particular to a heating and cooling circulation device. Background Art

[0002] The adsorption column is a commonly used technical means in the existing adsorption process. It is divided into an inner cylinder, an outer heating jacket and a cooling body. The adsorption column has a single heating and cooling cycle. The adsorption column is a commonly used separation and purification technology. Its working principle is based on the interaction principle between molecules and solid surfaces. When the sample is injected into the adsorption column, the target molecule interacts with the adsorbent, and the target molecule is adsorbed on the adsorbent surface, while other impurities are washed away through the adsorption column. Subsequently, by changing the flow conditions, such as pH value or ion concentration, the interaction between the adsorbent and the target molecule is changed, so that the target molecule is dissociated from the adsorbent. Finally, the target molecule is purified and collected, and the adsorbent in the adsorption column can be reused again. The adsorption column is widely used in pharmaceuticals, biotechnology, environmental monitoring and other fields due to its high efficiency, selectivity and wide applicability.

[0003] However, if a single existing adsorption column wants to adsorb more impurities, it can only be achieved by increasing the filler of the adsorption column or increasing the volume of the adsorption column. However, this will slow down the heating and cooling efficiency of the adsorption column, affecting work efficiency, and may even lead to incomplete activation and regeneration of the adsorption column, affecting the adsorption effect.

[0004] Based on the above existing problems, our company proposed corresponding equipment technology transformation after sufficient comparison and demonstration, and developed and designed a heating and cooling circulation device. Utility Model Content
