Description

Technical Field

[0001] This utility model specifically relates to an integrated device for gas-liquid separation and condensate collection, belonging to the field of MVR evaporation technology. Background Technology

[0002] Evaporation technology is a highly efficient and energy-saving separation and purification method applicable to various industrial and food processing fields. MVR (Multi-Release Vaporizer) evaporators, in particular, are energy-saving technologies that reuse the energy of their own generated secondary steam, converting mechanical energy into thermal energy, thereby reducing the need for external energy sources. The MVR process involves compressing low-temperature steam through a compressor, increasing its temperature, pressure, and enthalpy. The steam then enters a heat exchanger for condensation, maintaining the liquid at a boiling state to fully utilize the latent heat of the steam. Steam that would otherwise be wasted is now fully utilized, latent heat is recovered, and thermal efficiency is improved.

[0003] In the field of MVR evaporation, the secondary steam before entering the compressor needs to be separated into gas and liquid by a separator to reduce the amount of water droplets, material droplets, and foam entrained in the secondary steam. Simultaneously, condensate is also generated during compressor operation. Both of these condensates need to be collected, and since their temperature is not low, they need to be returned to the preheating system to exchange heat with the original liquid, fully utilizing their heat. Therefore, a device is needed to separate the steam into gas and liquid, collect the condensate, and pump it back to the preheating system for recycling.

[0004] Therefore, in order to address the shortcomings of existing technologies, an integrated gas-liquid separation and condensate collection device is proposed. Utility Model Content
