the bathroom water tank 3 has a water inlet which is connected in communication with the hot water outlet 12 of the heat exchanger 1 through a communication pipe 32 to receive the hot water of the heat exchanger 1; therefore, after cold water enters the heat exchanger, the heat exchanger is provided with a secondary flash steam inlet, the cold water is heated to a certain temperature through the waste heat of the secondary flash steam, and then the cold water is discharged and pushed to the bathroom water tank 3.
A liquid level meter 33 for measuring liquid level is arranged in the bathroom water tank 3; the controller 5 is in communication connection with the liquid level meter 33, and the controller 5 is in communication connection with the circulating water pump 2; this embodiment sets for the water level of bathroom water tank to a definite value, and when the level gauge detected that the water level of water tank was less than the setting value, the heat exchanger will be squeezed hot water into the water tank to guarantee that the water tank can continuously supply hot water.
The device can recycle secondary flash steam discharged from the factory equipment end, and the secondary flash steam is heated by exchange with cold water, and the cold water is heated to a certain temperature and then discharged to a bathroom water tank for bathing of factory staff. In this embodiment, the circulating water pumps 2 are provided in two groups, one for each use; the controller is powered by a power supply 51, cold water is pumped into the heat exchanger through a circulating water pump, and the circulating water pump is operated by the controller after being used.
In the present embodiment, a temperature gauge is provided inside the heat exchanger 1.
In the present embodiment, the heat exchanger 1 has an overflow port 16, a condensed water outlet 13, and an exhaust port 15.
It can be understood that, in order to maintain the water way through and the automatic water adding function of the heat exchanger, the device provided by the embodiment includes, but is not limited to, a stop valve, a check valve, a ball valve, etc., and the efficient and controllable work of the whole system is effectively ensured.
Example 2
This embodiment provides a flash distillation gas heat transfer system, this system includes the plant equipment terminal and the device of embodiment 1, the plant sets up the terminal and has secondary flash distillation gas discharge port, secondary flash distillation gas discharge port communicates with the flash vessel entry of heat exchanger.
The set of system device makes full use of secondary flash steam discharged at ordinary times, and water is heated by waste heat of the secondary flash steam, so that the cost of burning a boiler can be saved, the flash steam can be recovered in a centralized manner, the phenomenon of flash steam discharged to the air is eliminated, and the national environmental protection requirement is also met.
