On the recycling of condensate water
Thread Content
There is an existing project in which the condensate water from the plant area comes from various sources, including process applications, air conditioning systems, and heating systems used in winter; the total maximum amount of condensate water generated is 15 T/H. The steam source is a nearby thermal power plant; the condensate water is not recycled and must be discharged directly by Party A. I would like to use it for winter heating or for bathing workers after heat exchange. The question now is: what size should the condensate tank be if I use a closed system for recovery? And what material should the tank be made of? If the used hot water has not cooled down to below 40 degrees, is it still necessary to use a cooling tank to lower its temperature? Hey, it’s so large. Experts, please help discuss this. I am learning * in Chinese.
It seems like a big project; I don’t really understand it
If Party A doesn’t want it, why go through the trouble of making it? Isn’t this just creating problems for no reason? Moreover, whether it’s for winter heating or bathing, these are intermittent processes; to handle over 300 tons of hot water per day, you need a tank of that size. If it doesn’t affect the manufacturing process, then it’s better to use water specifically for that purpose
It’s not very useful. We used to go back to the boiler room in the thermoelectric workshop
If the pressure and temperature of the condensate water are unknown, it could be considered as a low-temperature heat source to optimize the existing heat exchange process of the device.
It’s really not very useful; after being used, it still has to be discarded. Consider the economic aspects – is it better to discard it right away or to use it first and then discard it? Calculate the overall cost!
Thank you all for your suggestions and opinions. I really want to start working on it right away; the key question is how to reduce the temperature My original idea was to take advantage of the lower temperature, as well as achieve energy savings. Does anyone know? Hmm, what’s the effect of mixing water from cooling ponds with wastewater from sewage treatment plants?
It is recommended to recover it into tanks through sealed pipelines, then pressurize it with a pump, cool it using a heat exchanger, and send it to a water treatment plant for reuse.
There was once a group company that had methods for utilizing condensate water； All of it is returned to the thermal power plant; part of it is used by the plant, while the untreated water is used for employees to wash clothes and take baths, and it is also sold to local bathhouses, thereby enabling full recovery of the costs associated with tap water.
Depending on the water quality, condensate recovery treatment can be adopted. As long as the water quality is not too poor, the treated water can still be used as feedwater for the process
