How to reduce the entry of condensate water caused by duct condensation into the compressor in MVR systems
Thread Content
It should be feasible to install a small reverse baffle before the straight section at the compressor inlet; if anyone has better methods, they might share them
The condensate in the MVR ducts is mainly present during the startup phase of the compressor; it rarely occurs during normal operation, unless there are significant fluctuations in the system. A reverse baffle can be installed about one to two meters ahead of the compressor inlet, with a small hole on the front side of this baffle that leads to the compressor’s condensate storage tank, allowing the condensate to be drained promptly
The compressor is in a superheated state during its operation； Additionally: there are condensate drainage pipes at the inlet and outlet of the compressor, as well as at the bottom of the compressor volute. If baffles are added, the impact on air flow velocity must be taken into account
Therefore, it is necessary to ensure that there is a straight pipe section behind the baffle before the inlet
Consider adding a gas-liquid separator
Could you please explain what a reverse baffle is? Where should the compressor condensate tank be located? If there is a certain degree of vacuum at the inlet, can water flow into the condensate tank?
It is a narrow baffle that is positioned at a 30-degree angle opposite to the direction of the airflow, with the purpose of preventing water flow from entering the compressor and causing damage due to the high-speed rotation of the impeller. Thanks to the pressure tap pipe, the pressure in the condensate tank is roughly the same as the pressure in the pipes; thus, the weight of the water can be used to drive it into the tank
