Description

Technical Field

[0002] Catalysts play a vital role in chemical reactions. They can significantly increase the rate of chemical reactions without changing the chemical equilibrium, and their own quality and chemical properties remain unchanged before and after the reaction. According to relevant statistics, more than 90% of industrial processes are inseparable from the participation of catalysts, covering many fields such as chemical industry, petrochemical industry, biochemistry, and environmental protection. There are also many types of catalysts, which can be divided into liquid catalysts and solid catalysts according to their state. It can be said that catalysts play a pivotal role in the modern chemical industry. It is crucial to add various catalysts to the production equipment in a timely and effective manner to maintain the smooth operation of production.

[0003] In carbonate production equipment, some liquid catalysts are in a solid state or a gel with poor fluidity at room temperature. Although general room temperature warehouses can meet the long-term storage needs of such catalysts, there are many inconveniences in the addition and configuration of such catalysts during the actual use of the production equipment. It often happens that when the catalyst needs to be added, it cannot be added to the production equipment in time due to its poor fluidity, which affects the smooth operation of the production equipment. For this reason, our company has launched research on a thermal insulation device for storing easily solidified liquids. Summary of the invention
