Does the pressure between the three stages of flash evaporation affect one another?

2010-11-05View Original

Thread Content

:(I’m a beginner.) . I would like to ask the experts on this forum whether there is any interaction between the pressures in high-pressure flash evaporation, low-pressure flash evaporation, and vacuum flash evaporation within the wastewater treatment process. For example, what effects might an increase in the pressure of high-pressure flash evaporation have on low-pressure flash evaporation? I hope everyone can explain it to me more clearly; I’m just starting to learn this. Thank you

In the sludge water treatment section, temperature is a key factor to consider. The temperature of the ash water entering the sedimentation tank should be around 50°C; too high a temperature can affect the effectiveness of the flocculants. Temperature is closely related to the pressure in the flash evaporation process – in other words, lower pressure results in lower temperature, and vice versa. The pressures in the three stages of flash evaporation are interrelated; if the pressure at the high-pressure flash stage increases, and no corresponding adjustments are made, it will inevitably lead to an increase in the pressure and temperature at the low-pressure flash stage, thereby affecting the vacuum level

Reply to 1# The tragedy of the gasification furnace: What was said on the 2nd floor makes a lot of sense. I would like to add that pressure fluctuations in the drainage from the gasification furnace have little impact on the third-stage flasher, as the pressure in the third-stage flasher is primarily determined by the vapor pressure. For example, the pressure in the high-flash tank is controlled by the pressure control valve at the vapor outlet of the high-flash condensate separation tank. If the amount of drainage from the gasification furnace suddenly increases or if the drainage temperature rises, this will lead to an increase in the pressure in the high-flash tank; in such cases, it is necessary to adjust the pressure control valve at the vapor outlet of the high-flash separation tank in order to maintain stable pressure there.

What was said about the first floor and the second floor makes a lot of sense. Support! ! !
