Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, specifically a gas-liquid separator with heat exchange. Background Technology

[0002] In industrial production, gas-liquid separation of high-temperature, mist-containing gases is a common and important process. Traditional gas-liquid separators mainly achieve gas-liquid phase separation through inertial separation, baffle separation, or adsorption-coalescing. Specifically, when a gas-liquid mixture flows through the obstruction structure (such as corrugated plates or baffles) within the separator, the gas, due to its lower density, is easily deflected, while the liquid impacts the wall surface and adheres due to inertia, subsequently converging and discharging under gravity. For fine mist droplets entrained in the gas phase, adsorption, coalescence, and separation of the droplets are typically achieved through multi-layer corrugated plates or blade structures.

[0003] However, existing technologies have the following shortcomings:

[0004] 1. Waste of thermal energy: High-temperature mist-containing gas carries a large amount of waste heat during the separation process, but traditional separators only focus on gas-liquid separation and do not effectively recover the waste heat in the gas, resulting in energy waste and increased production costs;

[0005] 2. Limited separation efficiency: For high-temperature and high-humidity gases, when relying solely on physical separation structures (such as corrugated plates), some droplets may be difficult to quickly cool and condense due to the excessively high gas temperature, affecting the separation effect.

[0006] Therefore, we propose a gas-liquid separator with heat exchange. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a gas-liquid separator with heat exchange, which has the following beneficial effects:

[0018] 1. This gas-liquid separator with heat exchange uses a hollow corrugated plate and matching liquid supply and outlet pipes to form a heat exchange channel, which enables high-temperature mist-containing gas to fully exchange heat with the liquid to be heated (such as boiler feedwater), effectively recovering waste heat from the gas, reducing energy waste, and lowering production costs.

[0019] 2. This gas-liquid separator with heat exchanger allows high-temperature gas to contact low-temperature liquid during the heat exchange process, which can accelerate the condensation of mist in the gas and make it easier for fine droplets to coalesce and grow, thereby improving the separation efficiency.

[0020] 3. This gas-liquid separator with heat exchange has staggered baffles inside the corrugated plate, which can extend the flow path of the liquid to be heated in the plate, increase the heat exchange time, improve the uniformity and efficiency of heat exchange, and ensure that the liquid fully absorbs the heat from the gas.
