Description

Technical Field

[0001] This utility model relates to the field of heat exchanger insulation technology, and more specifically to a detachable plate heat exchanger insulation device for a cleanroom for biological products. Background Technology

[0002] In the vaccine production field, the environmental temperature control requirements for vaccine bulk solution processing are extremely stringent to ensure the efficacy and safety of the vaccine bulk solution. Traditionally, the heating and refrigeration reactions of the bulk solution in vaccine production rely heavily on water baths and refrigerators. However, these methods suffer from drawbacks such as inaccurate temperature control, high energy consumption, and inconvenient operation. With the rapid development of pharmaceutical technology and the continuous improvement of vaccine quality requirements, process tanks have gradually become key equipment in vaccine production. Their core temperature control component is the plate heat exchanger, which plays a crucial role in precise temperature control and tank protection. However, if the plate heat exchanger is not insulated in the cleanroom, a large amount of condensate will be generated during low-temperature operation. This not only affects the cleanliness of the cleanroom but also reduces the temperature control rate of the tank, leading to refrigerant waste. Furthermore, prolonged condensate soaking can create stubborn water stains on the equipment surface or floor that are difficult to clean. Utility Model Content
