Heat Exchanger for Paper Mill Effluent
Paper mill sewage heat exchanger is an important equipment used to treat paper mill sewage and achieve energy exchange.
It mainly has the following types:
Plate Heat Exchanger
Compact structure, high heat transfer efficiency. Composed of a series of thin metal plates stacked on top of each other, forming a narrow channel between the plates for fluid flow.
For example, in a large paper mill, the use of plate heat exchanger to recover the thermal energy in the sewage, used to preheat the production water, significantly reducing energy consumption.
Tube Heat Exchanger
Including shell and tube and immersion type. Shell and tube heat exchanger consists of a shell and tube bundle, which has a high pressure resistance.
For example, a medium-sized paper mill uses shell-and-tube heat exchangers to transfer heat from sewage to the air used to dry paper, improving energy efficiency.
Spiral Plate Heat Exchanger
Made of two parallel metal plates rolled together, it has good self-cleaning ability.
A small paper mill effectively recovers heat from sewage through a spiral plate heat exchanger, which is used for heating the workshop in winter.
When choosing a paper mill sewage heat exchanger, you need to consider the temperature, flow rate, water quality, pressure and other factors of the sewage, as well as the heat exchanger's material corrosion resistance, heat transfer performance, maintenance costs and other aspects. The right heat exchanger can effectively recover the energy in the sewage, reduce production costs, and at the same time reduce thermal pollution of the environment.
