Description

Round trip heat collection type solar boiler

The utility model relates to a kind of round trip heat collection type solar boiler, is particularly suitable for the weather sky and uses.

People consider the utilization of solar energy in order to obtain a kind of solar energy from some approach.As known patent number is 94216432.6 " multistage intensification solar boilers ", adopts corrugation shape on the honorable structure of heat absorption, water temperature can be risen to 100 ℃ when sunny, and certain effect has been brought into play in the utilization of solar energy.

But known solar boiler is unreasonable to daylighting face structure Design, and the thermal efficiency is low, and is only limited to fine the use, do not have the water storage attemperator, even water temperature has raise, temperature will lower very soon during no solar light irradiation, it is faster that winter temperature falls, and uses inconvenient.

The purpose of the utility model round trip heat collection type solar boiler is the round-the-clock all spendable solar boiler of a kind of round trip heat collecting type rational in infrastructure, that the thermal efficiency is high of design on known solar boiler basis.

The utility model is described in further detail below in conjunction with drawings and Examples.

Referring to figs. 1 through the utility model that further specifies shown in Figure 5.

This boiler by: boiler cover plate (1), cold water storage cistern (2), boiler (3), water pipe (4), forward valve (5), electric heater (6), magnetizer (7,17), water-thermometer (8), ball valve (9), boiling water mouth (1 0), water intaking valve (11), water tank pore (12,21), framework (13), M type water core (14,15), insulation material (16), power line (18), heat-absorbing paint (19), support (20) are formed.

Round trip heat collection type solar boiler body is made up of framework (13), solar boiler cover plate (1), M type water core (14,15), heat-absorbing paint (19), insulation material.

Framework is made by aluminum alloy materials, round trip heat collection type solar boiler collector cover plate is made by Solar-E fiberglass light-passing board or plate glass material, be embedded in the top of framework, its light transmittance reaches 88%, this plate is in visible wavelength 250-2500mn, the sunlight light transmittance is＞90% at visible wavelength 390-760mn light transmittance more than 89%.The water core is made by metal aluminum sheet, and its structure is the M type.The water core is welded in the framework, and is connected with water inlet pipe and water outlet pipe, and the heat-absorbing material coated is on the water wicking surface, and insulation material is layered on the back side of water core.M type metallic aluminium water wicking surface layer is penetrated the sunlight width of cloth can have that secondary absorbs, increases daylighting area, improves the thermal-arrest ability, thermal efficiency height, from heavy and light, characteristics that anti-corrosive properties are good, ageing-resistant.It is that aluminium sheet is pressed into the two-pass type water route, with argon arc welding and bottom aluminium dull and stereotyped and up and down water inlet pipe be welded.Height of water level is 3-5mm, and minimum altitude is 2-3mm, and resistance to heat is little between the plate liquid, has than the higher thermal efficiency.The round trip heat collector adopts M type plane skylight, compare with corrugated plane skylight, the general line length in corrugated single surface is 30m, and the round trip heat collector is 38mm, increased more than 20% than corrugation shape plane skylight is single, the two-pass type heat collector is the round trip water intake mode, its water inlet direction is laterally vertically water inlet simultaneously, and its purpose is the liquid level height that staggers, high liquid level is 3-5mm, and low liquid level is 2-3mm, water-head has mobile fast, the advantage that resistance is little, reach the purpose that improves collecting efficiency, owing to adopt round trip heat collecting type M type thermal-arrest plate, solar energy is by secondary reflection and absorption, make the absorption energy be increased to 99%, improved Heat-collecting effect by 90%.

Scribble the extraordinary PA heat absorption blacking of developing voluntarily at the water wicking surface, increased endothermic effect.Adopting the insulation material code name of developing voluntarily at water core back is 311, has good heat insulation effect.

The boiler support is pressed the manufacturing of boiler size by three angle steel or other material and is installed, and it plays a part to support hydrophone.

Water tank is the columnar structured of a kind of new wall, is made of metallic plate and extraordinary insulation material 311.Have cold water water inlet assembly (valve and small pipeline), cold water storage cistern (2) and boiler (3) to be one in the water tank, an interlayer separates therebetween, is filled with insulation material (16) between the hot and cold water tank and combines.The hot and cold water tank has pore (21,12), and it is that cold water storage cistern is 20 kilograms that total casing holds water, and boiler is 30 kilograms.After 24 hours, water temperature keeps 67 ℃ in the insulation of boiling water state, keeps 48 ℃ through 48 hours water temperatures, and heat insulation effect is similar to thermos bottle.

Magnetizer is square magnetic patch, is fixed on the junction (7) and the boiler interior (17) of cold water pipe and water core.Water is magnetized through behind the magnetic patch, and magnetized drinking water can dissolve CaCO ₃, thereby be difficult for producing incrustation scale, drinking magnetized water is favourable to health.

Electric heater is to adopt 220 volts of 150-300W electric heaters of 2 phases, and electric heater (6) is fixed on the interior securing electric lines socket of boiled water tank.When sleety weather needs boiling water or hot water, can connect power supply, make electric heater energising heating.Temperature in the heat collector in the water core is observed by water-thermometer (8), so that grasp the water temperature situation.

The utility model round trip heat collection type solar boiler rose to 100 ℃ by 20 ℃ of initial water temperatures in about one hour when sunny, the cloudy day water temperature still can reach 50-70 ℃, when having solar radiation, the sleet sky can not make water temperature reach 100 ℃ with electric heater, 25 kilograms/platform of separate unit production water yield boiling water in summer, 200 kilograms/platform of hot water.Produce 20 kilograms/platform of boiling water winter, 150 kilograms/platform of hot water.Can reach more than 10 years service life.Every net weight is no more than 60 kilograms, can satisfy user's needs, if industrial and agricultural production needs, can many be contacted according to instructions for use, for user's instructions for use.

The round trip heat collection type solar boiler course of work:

Before using round trip heat collection type solar boiler, earlier solar boiler is moved the place of solar ray energy irradiation (direct projection).Close ball valve (9) after by water inlet pipe (11) water tank (2) being filled with water, water is under the effect of water tank air-vent in the cold water storage cistern, water can flow to M type water core by forward valve (5) through water pipe through water pipe (4) automatically, water passes through (14), (15) round trip water channel at M type water core, Natural Circulation heats up, water in the M type water core under the effect of forward valve, can not flow back in the cold water storage cistern after heating up.Observe the reading on the water-thermometer (8), when to required use water temperature, ball valve (9) is opened, open (heat) water and directly enter boiled water tank (3) by ball valve (9).Magnetic patch water is housed in the water inlet of water core and the boiled water tank is magnetized, use if desired, open water nozzle (10) and emit out (heat) water.As not closing water nozzle (10) simultaneously, allow and open (heat) water in the M type water core and directly flow to boiler and store standby with ball valve (9) being opened.

Sleety weather does not have solar radiation, earlier cold water storage cistern is filled with water, and ball valve (9) is opened, and cold water flows into boiler through water pipe, forward valve, water core.After water puts in place, connect the electric heater power supply and make electric heater work, when water is heated to temperature requiredly, pull up attaching plug immediately.At any time enable according to weather condition and use needs.
