Description

A kind of centralized domestic hot-water supply system suitable for Heating Period
Technical field
The utility model is related to urban heating technical field, more particularly to a kind of centralization suitable for Heating Period is for life Hot-water heating system.
Background technology
At present, with the improvement of people's life quality, requirement of the resident to the mount of using heat also increasingly increases.Using solar heat Hydrophone supplies domestic hot-water, although the stability of energy saving supplying hot water is insufficient, the confession of hot water is just can guarantee when only sunny It should;By the way of using region, boiler is combined with solar energy, though the stability of hot water supply is can guarantee, compared to centralized heat supply For water system, regional hot water boiler heat supplying water system energy consumption is larger, and supply water temperature is relatively unstable.
Invention content
User is ensured by secondary network hot water cyclesystem the technical problem to be solved by the utility model is to provide one kind The centralized domestic hot-water supply system of supply water temperature stability.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:A kind of collection suitable for Heating Period Chinese style domestic hot-water supply system, including:The primary net high-temperature-hot-water circulatory system, the secondary network domestic hot-water circulatory system, user side Domestic hot-water's circulatory system and several into, water return pipeline, the water supply of the primary net high-temperature-hot-water circulatory system is through plate-type heat-exchange Device, which exchanges heat, gives secondary network domestic hot-water, and the coupled tank of hot water of the secondary network domestic hot-water circulatory system enters user side life Hot water circuit supplies user.
User carries out moisturizing by small pump by the domestic water in water supply tank using after hot water to system.
Not used domestic hot-water is returned to by the water return pipeline of user side in coupling tank.
Secondary network hot water inlet pipe road is equipped with water circulating pump.
User side water supply line is equipped with water circulating pump.
Network pipeline is equipped with primary net temperature control adjusting valve, secondary network road is equipped with temperature control adjusting valve.
The beneficial effects of the utility model are:1. it is changed using the primary net high-temperature water of heat exchange station (95 DEG C/55 DEG C) by board-like Hot device and secondary network domestic hot-water heat exchange gained, while ensureing heat supply stability, realize making full use of for the energy, improve Energy utilization rate;2. setting coupling tank in system can not only make the hot tank of storage and use, secondary network life heat can also be isolated Water recycles the Seepage-stress coupling with user side domestic hot-water cycle, its hydraulic regime is made to be independent of each other;3. system devises secondary network Domestic hot-water recycles, and passes through temperature control adjusting valve and adjust its state of cyclic operation, is improving the same of the stability of domestic hot-water supply temperature When it is energy saving.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, the centralized hot-water supply system suitable for Heating Period is made of three cycles, it is that primary net is high respectively Warm water's cycle, secondary network domestic hot-water cycle and user side domestic hot-water cycle.The specific arrangement of system is shown in Fig. 2, once The supply water temperature of net high-temperature-hot-water cycle is 95 DEG C, and exchanging heat successively by dirt separator 1, plate heat exchanger 3, it is hot to live to secondary network Water, a net side return water temperature are 55 DEG C.Secondary network hot water after heat exchange under the action of water circulating pump 4, into coupling tank 5 with User side hot water mixed heat transfer so recycles, and ensures that the temperature of hot water in coupling tank 5 meets water supply requirement.User side feed pipe On road set water circulating pump 7, by hot water from coupling tank in be supplied at user, heat user using after hot water by being carried out through water softener 10 Domestic water after water process in water supply tank 8 carries out moisturizing by small pump 9 to system, and not used domestic hot-water passes through user The water return pipeline of side is returned to after the decontamination of dirt separator 11 in coupling tank, this system can meet the water demand of user at any time.For side Just counting user the mount of using heat, system water amount, the water return pipeline of primary net, secondary network in system have been respectively mounted calorimeter, Water meter is installed in moisturizing pipeline.
The power-economizing method that the utility model is applicable in the centralized hot-water supply system of Heating Period is as follows:
1. being used as heat source by plate heat exchanger water-water heat exchange, the usage quantity of hot-water boiler in cell is reduced, is improved Energy utilization rate, it is energy saving.
2. when use hot water user it is less when, the water that small pump fills into system is few, couple in-tank mixing water temperature Reduction amplitude is small, primary net, secondary network road temperature control adjusting valve amplitude can be reduced according to temperature suitably to reduce primary net high Warm water and the circular flow of secondary network domestic hot-water reduce energy consumption.
3. when use hot water user it is more when, the water that small pump fills into system is big, couple in-tank mixing water temperature Reduction amplitude is big, primary net, secondary network road temperature control adjusting valve can amplitude be reduced according to temperature and increase primary net high-temperature water With the circular flow of secondary network domestic hot-water, increase heat exchange amount, the temperature in coupling tank is allow to be rapidly achieved heat supply coolant-temperature gage Requirement, meet the water demand of user.
