Exhaust Gas Generated During Sludge Drying Recovered with Heat Exchangers

The tail gas generated during the sludge drying process can be recovered with a heat exchanger.

A specially designed tail gas heat exchanger can be used to recover the heat in the tail gas and use it to preheat the air or other media entering the drying system, improving the efficiency of energy utilisation.

In this way, energy consumption can be reduced and operating costs lowered. For example, a type of heat exchanger, such as finned tube heat exchanger or plate heat exchanger, is used to transfer the heat from the tail gas to the medium that needs to be heated.

At the same time, in the recovery process, it is also necessary to pay attention to the possible presence of corrosive components in the tail gas, particulate matter and other impacts on the heat exchanger, and it is necessary to take appropriate protective and cleaning measures to ensure that the heat exchanger can operate stably for a long period of time and effectively recover heat. In addition, it is also necessary to combine the specific characteristics of the tail gas and process requirements, the heat exchanger selection and operation parameters for reasonable optimisation, in order to achieve the best recovery effect and economic benefits.
