Abstract

The utility model discloses a solar boiler, which is composed of vacuum tubes, reflecting plates, a bracket and a heat insulating water tank; besides main reflecting plates, the utility model is also provided with side reflecting plates and lower reflecting plates, and each of the reflecting plates is composed of curved cylinder surfaces or is composed of the inscribed and the rcumscribed polygon cylinder surfaces of the curved cylinder surface. The heat efficiency is high, the vacuum tubes can be reduced by 50% per square meter, and the effect of the existing product can be achieved. The cost is greatly reduced; as the utility model is provided with an electric heating device, the use is flexible and convenient; the utility model can supply drinking water, and can also be used for heating. The utility model can provide the hot water whose temperature is between 70 DEG C and 100 DEG C for industry, and the suitability is good.

Description

Solar boiler

A kind of device that the utility model relates to utilize solar energy that water or other liquid medium are heated.

Present vacuum tube type solar energy water heater mainly is made of several major parts of heat collection glass evacuated pipe, reflecting plate, support and attemperater; The general a slice reflecting plate that only adopts planarized structure is arranged on the below of heat collection glass evacuated pipe, in order to sunshine is diffused into the lower surface of vacuum tube; The vertical vacuum tube of installing directly is connected with attemperater, and it need adopt more heat collection glass evacuated pipe to be arranged in parallel within the place ahead of plane reflection plate.The deficiencies in the prior art part mainly is: 1, the thermal efficiency is low, and solar water heater can go out 45 ℃ of hot water 45Kg/m every day in winter ², summer 120Kg/m ²Solar boiler, can go out boiling water 25Kg/m most effective every day in summer ², every day in winter 10Kg/m ²2, the quantity of used vacuum tube is many, and ten vacuum tubes need be set in every meter width usually, just can reach above-mentioned effect, complex structure, cost height.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of thermal efficiency height, the solar boiler product that cost is low.

Can take following technical scheme to realize purpose.This solar boiler, still mainly constitute by heat collection glass evacuated pipe, reflecting plate, support and attemperater, but it is except that the principal reflection plate of heat collection glass evacuated pipe below, also be provided with lateral reflection plate and following reflecting plate, and each reflecting plate adopts all the inside and outside polygon cylinder that connects of bent cylinder or bent cylinder to constitute in the both sides and the lower end of vacuum tube principal reflection plate.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of solar boiler;

Fig. 2 is that other of solar boiler plants structural representation;

Fig. 3 is a kind of structural representation of connector among Fig. 2.

This solar boiler, because lateral reflection plate 4 and following reflecting plate 5 have also been set up in both sides and lower end at vacuum tube principal reflection plate 3, they can utilize solar energy more fully in one day light application time, sunshine with the different incidence angles of different periods, sunlight as oblique fire, all can be used effectively, make that vacuum tube is more shone, heat time heating time, around vacuum tube, form the compact district of solar energy.Adding each reflecting plate all adopts the inside and outside polygon cylinder that connects of bent cylinder or bent cylinder to constitute; As the face of cylinder, elliptic cylinder, parabola cylinder, other curve cylinder or they inside and outside connects any in the polygon cylinder; When reflecting surface adopts the face of cylinder, when elliptic cylinder or they inside and outside connect a kind of formations in the polygon cylinder, vacuum tube was installed in axial ray, leans on cylinder side place; When reflecting surface adopted the inside and outside a kind of formation that connects in the polygon of parabola cylinder or it, vacuum tube was installed on the focusing axis of cylinder; This curved reflecting surface is the encirclement shape to vacuum tube, so can more effectively solar energy be reflexed on the respective surfaces of vacuum tube from each angle, the photo-thermal amount that every pipe is received is several times of plane product.Through test, by the technical program, 2～3 heat collection glass evacuated pipes are set in every meter width, can reach the effect of 10 pipes of plane.All can clearly illustrate from this two aspect, the thermal efficiency height of this solar boiler, cost reduces relatively.

From solar boiler example shown in the drawings, as can be seen, heat collection glass evacuated pipe 1 both can erect dress, but also level is installed, and their effectiveness is identical.

In the solar boiler example shown in the accompanying drawing 2, heat collection glass evacuated pipe 1 level one end is installed on the support 6, and the other end is connected with attemperater 2 by connector 7, pipe fitting, in the exit of connector temperature control valve 8 is housed.Cold water enters in connector and the vacuum tube from the bottom, connector is the cavity volume structure that has the vacuum tube mount pad, it is in order to store the heated liquid of each vacuum tube, make them under the control of temperature control valve, wouldn't enter attemperater, and between vacuum tube and connector, proceed to circulate, be heated once more, reach 100 ℃ or when setting value until water temperature, the temperature control valve is open-minded, boiling water or high-temperature high pressure water are sent to attemperater through pipe fitting, or supply to drink, or for heating, all can, so can be referred to as solar boiler.Its result of use is good.As for, the specific constructive form of connector, size etc. all can be taken the circumstances into consideration to set according to using needs, as long as satisfy above-mentioned instructions for use, can both guarantee the performance of this solar boiler; Its outside should be provided with heat-insulation layer, and at the spigot of each vacuum tube sealing ring is installed, and prevents to leak.

Solar boiler also can be installed electric heater 9 in connector, it is standby auxiliary equipment.When not good, the no solar time of weather, still can guarantee to supply with boiling water or heating, make the device operate as normal.

Temperature control valve and electric heater all can adopt existing various product.

The appearance that solar boiler, attemperater 2 and other need be incubated the position adopts thermal insulation coatings coated, high insulating effect.

The relative prior art of the technical program has following advantage and effect:

1, thermal efficiency height can obtain 100 ℃ high-temperature water.

2, the quantity of thermal-arrest glass-vacuum tube can reduce relatively, every square metre reduce 50% with On vacuum tube, can reach the effect of existing product; Product cost descends.

3, be provided with auxiliary electric heater unit, use more flexible, convenient.

But 4, both supplying drinking water also can supply heating usefulness, and also can be industry provides 70 ℃～100 ℃ hot water, and applicability is good.
