Description

Technical Field

[0001] This utility model belongs to the technical field of enamel condensers, specifically relating to an enamel plate condenser. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, condensers are commonly used devices to transfer heat from steam or other hot fluids to cold fluids, achieving the condensation process. Traditional condensers are typically made of metals such as copper and stainless steel, which have good thermal conductivity. However, in certain corrosive environments, metals are susceptible to corrosion, leading to shortened equipment lifespan and increased maintenance costs. To address this issue, enamel-lined condensers were developed. They utilize the excellent thermal conductivity and corrosion resistance of enamel materials, improving the condenser's applicability and durability in corrosive environments.

[0003] Currently, the condensing chamber in enamel-lined condensers has an internal hollow structure, resulting in a short residence time of cooling water within the condensing chamber and a short contact time between the water flow and the condensing plates. Due to the short contact time between the cooling water and the condensing plates, heat exchange is insufficient, leading to reduced condensing efficiency and affecting the heat exchange performance of the entire system.

[0004] Short flow time of cooling water within the condenser chamber can lead to uneven heat exchange, potentially causing overcooling or overheating in certain areas, thus affecting condensation efficiency and product quality. Low condensation efficiency means requiring more cooling water or lower cooling water temperatures to achieve the same condensation effect, which can result in energy waste and increased operating costs. The hollow internal structure design may limit the thickness of the condenser fins and the size of the condenser chamber, thereby limiting the condenser's heat exchange capacity and applicability.

[0005] In view of this, we propose an enamel-plated condenser to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the technical problem in the prior art where the cooling water has a short residence time in the condensation chamber and a short contact time between the water flow and the condenser fins, resulting in reduced condensation efficiency.
