The heat exchanger is a kind of device for energy recycling during galvanizing. It take advantage of the waste air from furnace heating system, the heat from the burning medium go through this device and exchange heat into water in pipe channel and pipe channel and heat exchanger conduct heat to fluxing tank to warm up the solution to almost 70 centigrade. It will warm up the steel pipes(work piece) during staying in fluxing tank.
There are following advantage for this:
1. Compared with cold work piece, the warm work piece will be more peaceful when dipping into zinc kettle. This condition will reduce zinc smoke.
2. Compared with cold work piece,the warm work piece will reduce the reaction time in zinc pot, so that reduce zinc consumption.
3. It will reduce water vapor content in zinc smoke and prolonging service life of bag filter for zinc fume.
