Furthermore, the deoxidization system include the deoxidization pump that sets up on the soft water inlet tube and with the oxygen-eliminating device that the deoxidization pump communicates. In the process that the soft water in the soft water tank flows in the soft water inlet pipe, the soft water can be cooled into low-temperature soft water through the water inlet pipe and the water outlet pipe of the oxygen removal pump, and then the soft water enters the waste heat recovery water tank.
When the utility model is in practical use, the continuous sewage in the boiler enters the coil pipe in the waste heat recovery water tank through the continuous exhaust expander, and enters the cooling pond after exchanging heat with the soft water in the waste heat recovery water tank and cooling; the soft water circulating unit provides low-temperature soft water for the waste heat recovery water tank and recovers high-temperature soft water discharged by the waste heat recovery water tank; the high-temperature soft water in the soft water circulating unit is cooled after passing through the deoxygenation system and enters the waste heat recovery water tank.
Compared with the prior art, the utility model has the characteristics of it is following:
1) The waste heat of the continuous sewage is fully utilized, and the heat of the continuous sewage is transferred to the soft water in the waste heat recovery water tank through the coil pipe, so that the temperature of the soft water in the soft water tank is increased, the high-temperature soft water is conveniently provided for the deaerator, the steam consumption of the deaerator is reduced, and the waste heat recovery and utilization are realized;
2) The temperature of continuous sewage entering the cooling tank is reduced, the cooling water consumption is reduced, the operation cost is reduced, and energy conservation and consumption reduction are realized.
