Standby service life length is used for steam power plant's steam heat recovery system.
The purpose of this utility model can be achieved through the following technical solutions：One kind is for steam power plant's steam heat recycling
System, the system include a shell-and-tube heat exchanger, steam, and the outlet of tube side are passed in the tube side of the shell-and-tube heat exchanger
It is equipped with condensed-water recovering device and condensate tank successively, the shell side of the shell-and-tube heat exchanger is connected by circulating hot water pipe with energy
Equipment, the condensate tank are connected by constant pressure supply water unit with the circulating hot water pipe.The utility model uses condensate tank
In condensation water give circulating hot water pipe's moisturizing, i.e., substitute the exceeded municipal administration of original chlorion using the steam condensate of height softening
Tap water reduces cost of water treatment, reduces Incrustation of pipe and corrosion risk as water supply source.In addition, due in this system
Condensation water be not recycled to steam power plant, so reducing its long-distance sand transport cost.
The constant pressure supply water unit is included for measuring the flow sensor of hot water flow in circulating hot water pipe, for general
Condensation water send the condensate pump into circulating hot water pipe from the condensate tank and is connect with flow sensor and be used to control
The controller of condensate pump opening and closing.It, can be with hot in automatic sensing circulating hot water pipe by the setting of flow sensor and controller
The changes in flow rate of water, timely and suitably moisturizing, ensures making full use of for steam waste heat, and high degree of automation.
The controller is PLC controller.
Connecting line between the condensate pump and circulating hot water pipe is equipped with check valve.
Centrifugal blower-pump is connected in the circulating hot water pipe, the centrifugal blower-pump is arranged on shell-and-tube heat exchanger shell side
Inlet.Centrifugal blower-pump is set, ensures circulation power of the hot water in circulating hot water pipe.
The condensate tank is equipped with discharge outlet, when condensation water aggregation is more, can discharge in time.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects：
(1) the exceeded municipal tap water of original chlorion is substituted as moisturizing water by the use of the steam condensate of height softening
Source reduces cost of water treatment, reduces Incrustation of pipe and corrosion risk；
(2) internal digestion steam condensate, reduces its long-distance sand transport cost；
(3) operation of original hot-water heating system, condensate system and recovering system for steam condensing water is not influenced.
