Seeking help regarding the secondary flash recovery of high-temperature condensate after flashing
Thread Content
The temperature of the high-temperature condensate water is 160 degrees, with a pressure of 20 kilograms. Through a single flash process, saturated flash vapor at a low pressure of 4 kilograms is produced. As the condensate water is discharged, a large amount of secondary flash vapor is generated again. I would like to ask everyone: apart from using a heat pump for extraction, are there any other methods for recovering and pressurizing this secondary flash vapor? I heard someone say that MVR devices can be used to increase the pressure and enthalpy of steam, is that true? Is there anything good to recommend? Please help me out with some suggestions; thank you very much
The mixing ratio of heat pumps is very low, and the unit price of medium-pressure steam is considerably higher than that of low-pressure steam, so its value is not significant. I wonder if there are any devices that can re-pressurize low-pressure flash steam?
Haha, are you generous? And the so-called secondary flashing for condensate discharge must already have very poor quality, right?
There are about 12 tons of condensate per hour, and after one flash evaporation process, around 10 tons of low-pressure steam is produced. However, the temperature of the condensate is still around 130 degrees, which is a waste. Is there any way to collect it and use it for a second flash evaporation at higher pressure? Can MVR equipment apply pressure?
Hot water can be considered for use in refrigerators (lithium bromide); the technology is well-established! ! !
An MVR evaporator, whose English abbreviation is Mechanical Vapor Recompression, is known as a “mechanical vapor recompression” evaporator. It involves connecting a mechanical compressor to a secondary steam system with continuous evaporation in order to improve the utilization rate of the secondary steam. Mechanical work is used to raise the temperature of the steam.
Secondary flash evaporation accounts for only about 13% of the total mass of all condensed water; due to its low density and large volume, it seems like there is a lot of it! To recycle the secondary flash vapor, it is recommended to add a condensate recovery system; feel free to message me if you need any assistance
The customer’s initial high-temperature condensate temperature was around 160 degrees, so we first installed a flash evaporation system. The condensate water after one flash evaporation is at around 120-130 degrees, with still a lot of residual heat; what equipment can be used to recover it? Could I have your phone number? Let’s communicate. Thank you
May I have your contact information? See if you can help come up with a solution, thanks
Since we’re all intermediaries, let’s support each other. If there is a cooling requirement, use chilled water ； A heat pump can also be used to generate steam, but the amount produced is relatively small ； Then there is low-temperature power generation. Using secondary flash evaporation to produce steam is too inefficient and not practical
