Description

The new type solar energy steam generator

The utility model relates to the steam generator in the solar energy equipment.

In background technology, China's utility model communique in May 3 nineteen ninety-five Granted publication " solar steam generator ", its patent No. is 94215904.7, notification number 2196233, its structure is to be connected by the bracing frame of heat collector by support and reflector, the bracing frame and the heat collector of foot rest supporting reflex device, characteristics are: the bracing frame of reflector links to each other with the expansion link of two oil pressure lifting platforms, the oil pressure lifting platform links to each other with oil pump by oil pipe, heat collector links to each other with heat exchanger, it utilizes oil to be heating working medium, and in the existing solar energy equipment, lighting equipment is flat and two kinds of forms of heat collecting type, the former unit are shortage of heat is to produce a large amount of steam, the latter can gather a large amount of light water is heated, but because the heat absorptivity of water is poor, poor effect.And be working medium with oil, the boiling point height, character is more stable, and thermal capacitance is big, and heat absorptivity is good, and is easy to use, and its operation principle is after earlier oil being heated to uniform temperature, water to be evaporated by heat exchanger again.But this equipment mechanism is complicated, can not heat water, and energy loses bigger in transfer, and manufacturing cost is higher, inconvenient maintenance.The purpose of this utility model is the problem that exists in the above-mentioned technology, designs a kind of new type solar energy steam generator, directly utilizes solar energy heating water to evaporate, and improves the conversion ratio and the utilization rate of energy, reduces cost, and uses easy to maintenance.

Technical solution of the present utility model is as follows:

Comprise that water pump 4 connects water tank 5, is characterized in that: solar steam generator 7 is separated three layers, and bottom is a reservoir bed 8, and the middle level is an evaporation rete 9, and the upper strata is a steam accommodating layer 10, and the water inlet 1 of steam generator 7 is connected water pump 4 and water tank 5 respectively with delivery port 2.

The new technical solution of this practicality also comprises:

In steam generator 7, steam accommodating layer 10 upper surfaces are transparent surface, and there is steam (vapor) outlet 3 side.

In steam generator 7, evaporate the capillary that is full of absorption solar energy generation heat in the rete 9 by the middle level that infiltrating material is made.

In steam generator 7, evaporate on rete 9 thin porous layers by the middle level that infiltrating material is made, implant fine hair 11 with absorption solar energy generation heat.

In steam generator 7, evaporate on rete 9 thin porous layers by the middle level that infiltrating material is made, draw fine hair 11 with absorption solar energy generation heat.

Assembling can be controlled the valve 12 of steam flow temperature and pressure on outlet 2 pipelines 6 of steam generator 7.

The utility model description of drawings is as follows:

Fig. 1 is the steam generator fundamental diagram.

Fig. 2 is the steam generator structural representation.

Fig. 3 is first kind of structure enlarged diagram of steam generation film.

Fig. 4 is second kind of structure enlarged diagram of steam generation film.

Above-mentioned number in the figure is described as follows:

1---the mouth of a river, 2---delivery port, 3---steam (vapor) outlet, 4---water pump, 5---water tank,

6---pipeline, 7---solar steam generator, 8---reservoir bed, 9---the evaporation rete,

10---the steam accommodating layer, 11---fine hair, 12---valve.

Be that the utility model adjoint is described in further detail below: referring to Fig. 1, delivery port 2 connects water tank 5 through pipeline 6 in the solar steam generator 7, water tank 5 ports of export connect inlet 1 through water pump 4, assembling valve 12 on the pipeline 6 at delivery port 2 places, the pressure and the temperature of control steam flow.Referring to Fig. 2, in solar steam generator 7, there are three layers, upper, middle and lower is respectively steam accommodating layer 10, evaporation rete 9 and reservoir bed 8, according to the daylighting condition, this upper, middle and lower also can tilt to place for three layers, also can tilt 90 ° or be inverted, water inlet 1 and delivery port 2 are arranged on reservoir bed 8, be first face above the steam accommodating layer 10, there is steam (vapor) outlet 3 side, connect mutually with jet chimney, evaporation rete 9 is a capillary structure layer, and lower surface links to each other with reservoir bed 8, upper surface links to each other with steam accommodating layer 10, the middle level is characteristics of the present utility model, and when evaporation rete 9 bottoms entered top with water by capillary, evaporation rete 9 tops absorbed daylight solar energy, make in the capillary and to store the moisture heat absorption and flash to steam, this capillary has heat absorption clarinet and suction double action capillaceous, and the capillary bottom ceaselessly absorbs water, and constantly evaporate on top, water tank 5 and water pump 4 provide the water source, form benign cycle.Referring to Fig. 3, this is the structure for amplifying of evaporation rete 9, and it can be made by light transmissive material, perhaps uses metal forming, and is perhaps made of plastic, surface-coated heatproof light absorbent.Referring to Fig. 4, this evaporating film 9 can form a large amount of capillaries like this by flocking 11 or napping 11 in the thin basic unit of heatproof porous, has both had the capillarity of suction, and the clarinet effect that absorbs luminous energy is arranged again.

Advantage of the present utility model and effect are as follows:

1. owing to directly utilize solar energy to evaporating the rete heating, so avoided adding with oil the indirect side of hot water in the past Method has improved energy utilization rate and power conversion rate.

2. the device that needs owing to heat transfer process in the middle of casting out, thus simple in structure, cost, use and maintenance side Just.

3. owing to adopt valve control outlet steam flow, so reached the outlet temperature of control steam and pressure Purpose.

4. be applicable to desalinization and the distillation of ion water of industrialization.
