Widely used Heat exchangers, Majority for Heating application. One media flow through the tube and other media over the tubes in the shell, so as to exchange of the heat.
Benefits
- Savings of substantial amount of Steam/Fuel.
- Reduced load on ETP as lower temperature effluent going to ETP.
- Reduced batch timings as in some cases hot water from the heat recovery system is used as input to the process.
- Boiler steam output increases as in some cases hot water from the heat recovery system is used as input to boiler feed water tank.
How it works?
The ETP Water is pass through the tank with submerged Type Heat Exchanger, the ambient temperature fresh water is pass through the secondary side ( inside the Tubular exchanger without any direct contact with the effluent water ) the secondary water will extract heat from the hot ETP Water reducing the hot ETP Water temperature & make it ETP friendly.
Heat Recovery from ETP Water
Textile processing operations are coming under increased scrutiny from environmental regulatory authorities because of the complex wastewaters and air emissions generated during the process.
In the textile industry steam is mainly use for heating water and drying. The hot water is use for various applications like washing, Bleaching and dyeing. As a need of process the hot liquor (water with chemicals) is drain & sent to ETP for the further treatment to maintain the BOD & COD levels before releasing to atmosphere.
