How can the heat from the superheated wastewater at the bottom of the distillation tower be utilized?
Thread Content
The superheated wastewater from the bottom of the distillation tower (at 108 degrees) was originally designed to be discharged directly after being cooled by cooling water. Now, with the owner’s emphasis on energy savings, how can this heat be utilized? The flow rate is 4 tons per hour, which is quite low; what can’t be done with such a low rate? I’m seeking help from all the seniors
Preheating the distillation feed allows for full utilization.
Energy conservation and emission reduction is an environmental protection policy that has been proposed. In my opinion, it can be utilized in the following ways: 1. For bathing and daily use in factories； 2. It is possible to preheat the containers containing the people who need to be heated ； 3. It can be collected for use in mixing materials, etc. . . .
1. Used to preheat the low-temperature medium entering the distillation tower； 2. Is such hot water required inside the device as flushing water, or for use in insulation bypass pipes and jackets? ； 3. It can be used as a heat source for small air conditioners; however, it shouldn’t be too small. It is advisable to consult a professional manufacturer to determine whether it is cost-effective.
Due to the operational temperature limits of the distillation tower, the material fed into it does not need to be preheated. There is too little water available for this purpose, and no other containers can be used either. What should be done?
It can be checked whether other sections and workshops can make use of it.
1. If this device, or other devices owned by the same owner, have equipment that requires heating, it can be utilized. 2. Whether heat tracing is needed. If none of the above conditions are met, then discharging the water into the fire suppression tank can be considered
There is no understanding of the process or basic conditions of the LZ device, nor is the composition of the wastewater known. For wastewater at this temperature and flow rate, it is still advisable to use it locally, primarily for heat exchange.
Preheat the feed material or use it for heating other processes, thereby reducing temperature-related emissions
Water at this temperature can be used to replace some of the low-pressure steam. Otherwise, just send it directly to the steam grid. However, the water needs to be desalinated. It is possible to use cooled deionized water for cooling; after use, it is sent for deoxygenation before being fed into the steam boiler.
