Description

Solar water heater self-loopa attemperater

The utility model relates to solar utilizing equipment, is specifically related to use on a kind of solar water heater, can be by realize the self-loopa attemperater of long-time insulation from the body circulation.

Solar energy is one of the cleanest energy of generally acknowledging in the world, people in the long-term production of using conventional energy resource (as coal, oil etc.), practical experience of life, when enjoying their " grace " for the human light and heat that brings, also tasted varieties of the disaster that these non-clear energy sources cause to the mankind, the most outstanding is exactly the environmental pollution that is caused in the process of using these energy or its product.Atmosphere pollution is the most outstanding example, and the formation of " mist is all " has one by one beaten alarm bell for human using energy source structure---must the new more clean energy of development and use.Solar energy is exactly one of human use's energy the earliest, but owing to technical reason, no matter human utilization to solar energy from quantity or on quality (efficient), all far reaches the desired and real available level of people.The efficient of solar energy when being converted into the energy form that can directly utilize is lower, and high-level utilization also is difficult to industrialization, and the easiest utilizes mode with regard to solar water heater.Existing solar water heater structure all is made up of a solar heat-collection plate and a water storage box basically.The insulating power of the water storage box of the solar water heater of this structure is poor, generally only can be incubated one day or the shorter time, therefore it only to be suitable for the sunshine-duration long, use in the area of the few and lasting weak point of rainy weather, and just be difficult to bring into play its cleaning, effect easily for the more area of those cloudy weather for several days running weather.The popularization that has also influenced solar water heater thus greatly is with universal.The design people once developed a kind of multistage box body combinations formula circulation attemperater, and applied for utility model patent (application number is 99232011.9), through long-term putting into practice, study, on intrinsic basis, developed a kind of solar water heater self-loopa attemperater that can pass through to realize long-time insulation from the body circulation, its heat insulation effect of evidence is good, and processing and fabricating is more easy, reduces cost.

It is a kind of simple in structure that the purpose of this utility model is to provide, and the processing and fabricating cost is cheap, the solar water heater that can be incubated for a long time self-loopa attemperater.

The utility model is achieved in that its water tank is a monolithic construction, the centre is provided with one or more layers circulation diaphragm, water tank is divided into main boiler and one or more cyclic water tank, set up the hot and cold water circulation pipe on the diaphragm separately, the water tank outside is covered with heat-insulation layer, cyclic water tank is provided with the water inlet pipe and water outlet pipe that is connected with the hot-water line and the cold water pipe of solar heat-collection plate respectively, the circulation pipe of hot water between cyclic water tank and main boiler enters main boiler, draws through the hot water outlet on main boiler top again.

Because adopting, the utility model separates water conservancy diversion thermal cycle and insulation construction design in the water tank, reduce the loss of heat, improved the service efficiency of solar water heater, can satisfy the requirement of the long-time insulation of hot water, and its structure is more easy, is easier to processing and fabricating.

Below in conjunction with accompanying drawing and embodiment the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.

Fig. 1 is the agent structure half sectional view of a kind of horizontal individual layer loop structure embodiment of the utility model;

Fig. 2 is the agent structure half sectional view of a kind of vertical individual layer loop structure embodiment of the utility model;

Fig. 3 is the agent structure half sectional view of the another kind of vertical multilayer loop structure embodiment of the utility model.

As shown in the figure, the water tank of the utility model is a monolithic construction, and the centre is provided with one or more layers circulation diaphragm 13, and water tank is divided into main boiler 2 and one or more cyclic water tank 1, set up heat, cool water circulating pipe 6,8 on the diaphragm 13 separately, diaphragm 13 subordinates are provided with support frame 14; The water tank outside is covered with heat-insulation layer 3, cyclic water tank 1 is provided with the water inlet pipe and water outlet pipe 4,5 that is connected with the hot-water line and the cold water pipe of solar heat-collection plate respectively, the circulation pipe 6 of hot water between cyclic water tank 1 and main boiler 2 enters main boiler 2, draws through the hot water outlet 7 on main boiler 2 tops again.

Supply tank 11 is connected with the cold water pipes 5 of cyclic water tank 1 and the cold water pipe of solar heat-collection plate by three-way pipe in the usual way by the pipeline of its underpart.

The top of main boiler 2 is provided with bleeder pipe 9, and the bottom of water tank is equipped with decontamination orifice 10.

By Fig. 1,2 as can be seen, be provided with one deck circulation diaphragm 13 in the integrated water tank, water tank is divided into a main boiler 2 and a cyclic water tank 1.Fig. 1 embodiment is horizontal individual layer loop structure, and Fig. 2 is vertical individual layer loop structure.Water tank is generally cylinder, also can be other forms, does not influence the realization of the utility model function.

Embodiment shown in Figure 3 is vertical multilayer loop structure, wherein be provided with 4 layers of circulation diaphragm 13, water tank is divided into 4 cyclic water tanks 1 and a main boiler 2, and simultaneously " manhole " 12 that uses when overhauling box house that is interconnected arranged at the bottom of the top of each casing and adjacent water tank.The water tank of structure is used for large-scale heating system more shown in this embodiment, as the villa dwelling house, and the central heating in hotel, apartment etc.

The utility model adopts single-stage, two-stage, three grades, level Four or more multistage loop structure, all can realize the purpose of the utility model.Multistage circulation is more conducive to the hot and cold water layering and uses, and improves thermal water utilization efficient.

Characteristics of the present utility model:

1, integrated water tank iris type structure makes structure simpler, thereby has reduced the processing and fabricating cost;

2, loop structure of the present utility model is so that hot and cold water can layering be stored in the different water tanks instant heating Water is stored in the main boiler all the time;

3, remarkable to the heat insulation effect of hot water, can keep for a long time having in the water tank can be for the hot water that at any time uses. At continuous rainy weather, can be incubated 3～5 days or the longer time, the round-the-clock hot water that provides has been provided basically.

In sum, the utility model can improve the comprehensive utilization ratio of solar water heater greatly, has overcome the drawback that hot water that prior solar water heater produces can not be incubated for a long time.Promote the use of the utility model, utilize the technology of this clear energy sources of solar energy to have positive promotion and facilitation accelerating to popularize.
