Abstract
The utility model relates to a novel direct flow glass vacuum tube solar water heater. In the direct flow glass vacuum tube solar water heater, a glass vacuum tube is used as a heat absorbing element; a direct flow constant temperature discharge way is adopted. The direct flow glass vacuum tube solar water heater mainly comprises a glass vacuum solar heat collecting tube with an inserting bar, a temperature-sensing valve, a bracket, a collector, an elevated water tank, a heat-insulating hot water tank, etc. The direct flow glass vacuum tube solar water heater is characterized in that the boiled water supply is quick; a plurality of units can be combined into a large boiled water system.
Description
The utility model relates to and utilizes glass-vacuum tube to collect solar energy in the solar energy heat utilization field, cold water is heated into the solar boiler of boiling water.
Utilize solar energy to provide boiling water required for people in many occasions, particularly lack the area of fuel at some, such demand is more urgent.The device that utilizes solar energy to boil water such as solar cooker, focusing boiler and honeycomb heat collector etc. was once arranged both at home and abroad, but all needed more operation and maintenance, complex structure because of existing to some extent, cost is too high, problems such as efficient is lower, and the life-span is long have influenced it and have used and promote.In recent years, China's development and production glass vacuum heat collection tube of solar energy, provide new approach for utilizing the solar energy heating boiling water.
The vacuum heat collection pipe of China's use at present is all-glass vacuum tube more than 98%.But directly adopt glass-vacuum tube to make boiler and have many difficulties: if the vacuum tube north-south is placed, the boiling water in the pipe can't take out fully, will lose more than 50%; If the vacuum tube East and West direction is placed, absorbing solar radiant energy will lose about 10%, this moment as employing top water mode, boiling water in the system bottom still can't take out fully, it is identical when loss is placed with the vacuum tube north-south, as adopt water descharging type, though the boiling water in the pipe can all take out, still in the glass-vacuum tube that is heated, lead to the danger that cold water has bombing immediately.
Have the proposition of the glass vacuum heat collection tube of solar energy of inserted rod, provide possibility for using glass-vacuum tube to make boiler.Under the situation of glass-vacuum tube north-south placement, owing in the pipe inserted rod is arranged, make the boiling water that can't take out only account for about 10% of boiling water total amount, the time that goes out boiling water also shortens dramatically.
The purpose of this utility model just provide a kind of thermal efficiency height, simple in structure, need not be automatically controlled, safe and reliable to operation, and can be a plurality of the solar boiler that uses of unit combination.
The technical solution of the utility model is: each unit of boiler is made up of 20 glass-vacuum tubes, is provided with inserted rod in the vacuum tube pipe to reduce the water capacity of vacuum tube, shortens the boiling water time.The vacuum tube north-south is placed on the support that has back reflector, and its openend is communicated with the East and West direction collector by sealing gasket.The collector two ends are provided with a silk pipe nipple, and collector one end is equipped with temperature-sensing valve and blast pipe, and the water side of temperature-sensing valve links to each other with outlet pipe, and the delivery port place is provided with the insulation boiled water tank, and the other end is equipped with water inlet pipe, and the front end of water inlet pipe is provided with high-order break pressure cistern.Having when solar radiation in the glass-vacuum tube of selective absorption surface on the pipe, make the intensification of being heated of water in the pipe, and make water heating in the collector by the free convection mode, when water temperature reaches or during near 100 ℃, temperature-sensing valve is opened automatically, boiling water flows out collector by the pressure of water in the elevated tank, enters boiled water tank, and cold water is then covered by water inlet pipe.
But the utlity model has out the characteristics of fast, the simple in structure multiple-unit combination of boiling water.Maximum can form 40 square metres large-scale boiling water system, have good use promotional value by 20 unit.
Below in conjunction with drawings and Examples the utility model is further specified.

Single flow glass vacuum tube solar energy as shown in Figure 1 and Figure 2 can be made up of 20 glass-vacuum tubes (1) each unit of boiler, is provided with inserted rod (2) in the vacuum tube (1).Vacuum tube (1) north-south is placed on the support (4) that has back reflector (3), and its openend is communicated with East and West direction collector (6) by sealing gasket (5).Vacuum tube (1) tail end is fixed on the support (4) by tailstock (7), collector (6) two ends are provided with a silk pipe nipple (8), one end is equipped with temperature-sensing valve (9) and blast pipe (10), the same outlet pipe in water side (11) of temperature-sensing valve (9) links to each other, and the delivery port place is provided with insulation boiled water tank (12).The other end is equipped with water inlet pipe (13), and the front end of water inlet pipe (13) is provided with high-order break pressure cistern (14).Insulation material (15) and shell (16) are arranged outside the collector (6).
Boiler adopts temperature-sensing valve direct current constant temperature delivery water mode, and each unit daylighting area is about 2 square metres, and a day maximum product minable water yield is 40kg.Install the hot water temperature-sensing valve, then can produce 50 ℃ of hot water 200-250kg daily.The angle on vacuum tube and ground should be local latitude on the boiler.In the area of latitude, can place by 30 degree less than 30 degree.The small-sized boiler in unit can be installed steamboat, so that suitably rotational orientation is followed the tracks of the sun.This utility model can also be combined into large tracts of land boiling water system in a plurality of unit (generally being no more than 20 unit), and maximum daily output minable water yield can reach 800kg.All can annually use in the area that is not less than-5 ℃ at not icing and the lowest temperature.
Claims (2)
1, a kind of is heat absorbing element with the glass-vacuum tube, adopt direct current constant temperature delivery water mode, the solar boiler of forming by critical pieces such as glass-vacuum tube, temperature-sensing valve, support, collector, elevated tanks, it is characterized in that: the collector two ends are provided with a silk pipe nipple, one end connects temperature-sensing valve, and the other end connects water inlet pipe or in parallel with other unit.
