Description
Technical field
This utility model relates to a kind of hot water cyclesystem, particularly relates to a kind of hot water cyclesystem on steam generator, belongs to heating and ventilation project field.
Background technology
In existing steam generator, the watering cycle route of vaporizer is essentially: after the water of room temperature is processed by water treatment system, the energy-saving appliance being passed through under steam generator exhaust opening tentatively heats, then pass to reach more than 90 DEG C after a plate type heat exchanger heats further, being passed through deoxygenation water tank again and carry out deoxygenation, the hot water after deoxygenation is passed through the heat exchange coil in steam generator again to carry out being boiled into steam after some heating；In deoxygenation water tank would generally designated water level induction apparatus, when water level is higher than the setting extremely high value of deoxygenation water tank, the water pipe being passed through energy-saving appliance is cut off, and now, the water in energy-saving appliance is owing to no longer flowing, it is easy to gasify because temperature is too high, has the danger producing booster.
Utility model content
For overcoming drawbacks described above, this utility model aims to provide a kind of, feed pipe too high at deoxygenation cistern water level and cuts off when supplying water, moreover it is possible to ensures the water proper flow in energy-saving appliance, prevented thermal evaporation steam generator hot water cyclesystem.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of steam generator hot water cyclesystem, including a softened water tank, one deoxygenation water tank and a plate type heat exchanger, it is provided with level sensor in described deoxygenation water tank, described softened water tank is connected with energy-saving appliance by a water inlet pipe, described water inlet pipe is provided with an electromagnetic valve, described energy-saving appliance is connected with plate type heat exchanger, described plate type heat exchanger is connected with deoxygenation water tank, described deoxygenation water tank is connected with coil heat exchanger, a circulating water pipe it is additionally provided with between described deoxygenation water tank and energy-saving appliance, described circulating water pipe is provided with a circulating pump and a check valve to energy-saving appliance conducting, described electromagnetic valve, level sensor and circulating pump are connected with control centre signal respectively.
Have employed steam generator hot water cyclesystem of the present utility model, after deoxygenation water tank high water level, electromagnetic valve cut off the softened water tank water supply to energy-saving appliance, by circulating water pipe, the water in deoxygenation water tank is passed through energy-saving appliance, the flowing of water in guarantee energy-saving appliance, it is to avoid water produces the generation of pipe explosion accident because crossing thermal evaporation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-softened water tank, 2-deoxygenation water tank, 3-plate type heat exchanger, 4-water inlet pipe, 5-energy-saving appliance, 6-coil heat exchanger, 7-level sensor, 8-circulating pump, 9-check valve, 10-electromagnetic valve, 12-circulating water pipe.
Detailed description of the invention
nullAs shown in Figure 1，The utility model discloses a kind of steam generator hot water cyclesystem，Including a softened water tank 1、One deoxygenation water tank 2 and a plate type heat exchanger 3，It is provided with level sensor 7 in described deoxygenation water tank 2，Described softened water tank 1 is connected with energy-saving appliance 5 by a water inlet pipe 4，Described water inlet pipe 4 is provided with an electromagnetic valve 10，Described energy-saving appliance 5 is connected with plate type heat exchanger 3，Described plate type heat exchanger 3 is connected with deoxygenation water tank 2，Described deoxygenation water tank 2 is connected with coil heat exchanger 6，The water of room temperature，First soften after being passed through softened water tank 1 such as tap water，To reduce water hardness，Prevent Incrustation of pipe，Then it is passed through energy-saving appliance 5 by water inlet pipe 4，Utilize waste heat that water is preheated，It is passed through plate type heat exchanger 3 the most again to carry out being heated to the hot water of more than 90 DEG C into a bit，It is passed through deoxygenation water tank 2 again and carries out deoxygenation，Finally it is passed through coil heat exchanger 6 and carries out heat exchange acquisition steam，In sum，Basically identical with the structure of existing steam generator hot water cyclesystem.
The innovative point of steam generator hot water cyclesystem described in the utility model essentially consists in and is additionally provided with a circulating water pipe 12 between described deoxygenation water tank 2 and energy-saving appliance 5, described circulating water pipe 12 is provided with a circulating pump 8 and one check valve 9 to energy-saving appliance 5 conducting, and described electromagnetic valve 10, level sensor 7 and circulating pump 8 are connected with control centre signal respectively.
Embodiment: when the water level in deoxygenation water tank 2 arrives higher limit, level sensor 7 is signaled to control centre, control centre sends instruction and closes electromagnetic valve 10, make softened water tank 1 stop energy-saving appliance 5 to supply water, meanwhile, control centre sends instruction ON cycle pump 8, makes deoxygenation water tank 2 be supplied water energy-saving appliance 5 by circulating water pipe 12, prevents energy-saving appliance 5 to be heated gasification because in-pipe flow stops.
Current when check valve 9 is possible to prevent softened water tank 1 to supply water energy-saving appliance 5 flow directly into deoxygenation water tank 2.
