Description

HEAT DRIVEN SELF-CIRCULATING FLUID HEATING
AND STORAGE TANK AND SYSTEM

FIELD OF TECHNOLOGY

The present disclosure relates to fluid heating and storage tanks, especially relates to the fluid heating and storage tanks having double walls. It also relates to heat driven and self-circulating fluid heating and storage systems using the tanks and having multiple energy sources, especially the solar heat collectors.

BACKGROUND
At present the solar heat application is becoming more and more popular. To reduce the hardware, software, installation, operation and maintenance costs, the applicant of this application disclosed a self-powered pump and liquid heat drive and self-circulation technology in the patent applications No. CA2628605 and PCT 2009000531. In another patent application CA2678584, the applicant of this application further disclosed several liquid heat driven and self-circulating systems. All these systems need the basic equipment-fluid heating and storage tank. The tanks described in above-mentioned patent applications are different in construction in the above mentioned systems. It is not convenient for manufacture and installation. One purpose of this application is to develop tanks for the heat driven self-circulating solar heating and storage systems by standard and modularization manufacture.

The solar energy varies in different seasons, locations and weather. Thus the solar energy in the solar heat collected in a solar heating system is not steady. It is expected by solar energy customers that a fluid heating and storage tank can be used not only for solar energy, but also for other energy sources.

Many efforts have been made to integrate the solar heating system with the building in last few decades. The liquid heat driven and self-circulating technology has made the integration of the solar heating system with the buildings much easier. It is the third purpose of this invention to make the solar heating systems an integral structure part of the module units of the building.
The fluid heating and storage tanks with double walls are presently known.
However, the existing tanks can not be used for heat driven and self-circulation fluid heating and storage system when the tank is not located higher than the heater. The existing tanks for multi-energy sources also can not be used in a heat driven and self-circulation system.

The liquid vaporizing and escaping of the heating liquid is a risk for the continue safety operation of a heat driven and self-circulation liquid heating and storage system. Some solutions to solve such problem have been developed in above-mentioned patent applications. This disclosure provides an improved and more efficient liquid vapor condensing and reclaiming apparatus.

SUMMERY:

The present disclosure aims at the new requirements of solar heat applications and also includes the improvement to our pending patent technologies.

In one aspect, the present disclosure is to provide two layer wall fluid heating and storage tank for the heat driven self-circulating solar heating and storage systems by standard and modularization manufacture.

In another aspect, the present disclosure is to provide the heat driven self-circulating fluid heating and storage systems employing above-mentioned fluid heating and storage tank.

DETAILED DISCRIPTION

The fluid heating and storage tank 10 in Fig.I is a water tank. It has an interior container l I 1 comprising sidewall 112, a top cap 113, a bottom capl 14 to form an enclosed space 110 for a first fluid, which is water. The tank has a cold water inlet 131 and a hot water outlet 132, a release valve 133 at the top (it may at the sidewall too), a drain valve 135 and one electric power heater 136. Of cause two electric power heaters can be provided if it is necessary.

A column-shaped (or other shaped) second layer wall 1 I5 is arranged outside of the interior container 111. Its top cap (here is a ring) 117 is mounted at the sidewall of the tank and its bottom 118 is under the bottom edge 116 of the interior container. Such that the container 119 or second space is enclosed by the bottom cap and sidewall 112 of the interior container, outer wall 115, ring 117 and bottom cap 118. The second container is for the second fluid, which is a liquid e.g. water or ethylene glycol etc.

At the second wall the inlets 121 and 123, outlets 122 and 124 are arranged for a secondary fluid.
The outlet 122 and 124 are not higher than the outlet 121 and 123 to sure the self-circulating of the heated liquid. At the bottom cap of second wall there are may some struts 128 and 129 are provide to support the interior container for the second wall.

The heat of the container 119 is transferred to the fluid in the interior container 111 through the sidewall 1 12 and the bottom capl 14. So that the material of the interior-container needs to be a heat conductive material e.g. copper, aluminum, stainless steel or steel plated glass or porcelain enamel.

A breathing channel extends upwardly from the top port 125 and it is connected to the breathing fitting 126 at the top of the tank.

A second fluid condensing and reclaim apparatus 51 is connected at the fitting 126. Fig.3 is a schematic diagram illustrating the apparatus 51.

The apparatus 51 is an airtight container. It has a top 511 and a bottom 512 and sidewall 513. An inlet pipe 52 having its one end extending upwardly from the bottom into the container and is mounted to the bottom of the container. In Fig. 3, the inlet pipe 52 is a hollow bolt. Its opposite end 522 can be revolved directly into the breathing fitting at the top of the tank.

A flexural U-shaped pipe 53 (it may be many other shape pipes, e.g. W-shaped etc.) extends its one end 531 from the sidewall of the container 51 into the container and under the tope wall 511.
Its upper end is spaced from the top wall. The other parts including its lower part of the pipe are located outside of the tank. The pipe extents its opposite end downwardly first and then upwardly.
So that the opposite end of pipe 53 is facing upwardly and its lower part 533 is located near to the bottom of the container.

Referring to Fig. 4, an alternative fluid vapor condensing and reclaiming apparatus is Illustrated.
Except U-shaped tube 63, other parts of this second embodiment are similar to apparatus 51 described above. The reference numerals in this drawing are changed from the first digital 5 to 6. Otherwise the construction is similar to apparatus 51 described above, A U-shaped tube 63 extends upwardly its one end 634 from the bottom 612 of the container 61 into the container and under the top wall 611. There is a gap between the end and the top wall. In Figure 6, the apparatus provides the breathing for the liquid due to expansion and contraction. A
small amount of condensed liquid is retained at the bottom part of the apparatus 61, which prevents further vapor from escaping into the atmosphere through the U-shaped tube 63.

Fig.4 is a schematic diagram illustrating another kind of apparatus for liquid vapor condensing and reclaiming. The feature of above mentioned container is to condense the liquid vapor in the container and let the condensed liquid returns to the heater. Usually any inside wall of a container at the temperature less than 100 degree can make the vapor condensing. Usually any metal, e,g. plastic, glass or polymeric material, can be used for making the container, When the system and environment temperature is high, in order to speed up the condensing processing, some condensing pieces may be installed in the container (did not shown in the Fig.3 and 4). The flexural pipe 63 also needs to make the vapor condense in the tube.
Furthermore, at the U shaped lower part of the pipe a few condensed liquid can be stored temporary to block the escaping of the escaped vapor. The flexural pipe can be made of many different materials e.g. glass, metal, plastic, polymeric material etc. The shapes of the pipe are flexible, e.g. U
shaped, W shaped or the like in which the bottom part of the pipe can store some condensed liquid.
Transparent pipes may be used to provide visible monitoring of the condensed liquid.

One of the main concerns for an operating heat driven self-circulating fluid heating and storage tank e.g. solar heating system is the fluid vaporizing and the vapor escaping through the breathing port. It may result a fail of the system operation. The application of the above introduced apparatus for fluid condensing and reclaiming resolves this problem completely.
Usually the container of the apparatus are made of transparency materials, e.g. transparent glass, plastic or polymeric materials, thus the liquid level of the heat exchanger can be visually monitored, and the more liquid can be added through the breathing port if it is necessary.

When the position of the secondary bottom wall is moved upwardly until it is connecting to the edge of the first bottom wall, the tank becomes a fluid heating and storage tank with double sidewalls. Fig.5 also illustrates the operation situation of a tank with double side walls but without double bottom wall.

There are two spare bolt caps for closing the unused inlet and outlet and one spare bolt cap for closing the unused breathing fitting. If necessary, all the breathing ports can be closed. In this case, the tank can be used as a regular tank with heat exchanger or used with self-power pump or electric pump.

Fig.2 is schematic diagram illustrating the fluid heating and storage tank with double bottom walls, which is a columned water tank 20. The columned sidewall 201, coronary top cap 202 and bottom cap 203 form a closed space 21 for primary fluid, which can be water.
The sidewall 201 extends from the bottom edge 206 and forms a new extended sidewall 204. The sidewall 204 together with the first bottom wall 203 and the second bottom wall 205 enclose a second space 22 for the secondary fluid which can be water or a antifreeze e.g. glycol etc.
On the sidewall 201 of the tank, there are two pipes 208 and 209 arranged in 180 relative to one another. Their lower ends 221 and 222 extended respectively through the sidewall and into the second space 22.
The other ends 223 and 224 extended upwardly around the sidewall and are connected to a three-way pipe joint. The upper end of the three-way pipe extends to the top of the tank. The third port of the three -way pipe is for connecting to the heater of secondary fluid. The two tubes 208 and 209 may be other kinds of channels. For example they may be two slots to cling at the surface of the sidewall. One end of these tubes extends into the second space and the opposite end extends to the top of the tank. For the rust protection purpose, the inside of the channels need to plat glass or porcelain enamel. Alternatively, the tubes or channels may be arranged inside of the tanks.
The ends of the pipes or channels also may be located at some locations under the top of the tank.
The angle of the two pipes 208 and 209 on the sidewall of the tank may also be located at 90 degrees or other selected angles.

At the sidewall near the bottom, the outlets 212 and 214 of the secondary fluid are arranged. Fig.
also shows that the second space of the tank is separated into two left and right sub-spaces by a clapboard 207. The liquids in these two sub-spaces are isolated. There are two separated sub-liquid systems in the second space. This kind of the system is used for two kinds of heaters in the two sides of the tank. Especially it is used for the system wherein one heater requires the forced circulating. For example, first heater is a solar heater and second heater is another energy heater which needs a forced circulating, e.g. earth energy or air energy. For using some r energy source, e.g. biomes energy, gas energy and fossil fuel energy, if there is no need of a forced circulation, the secondary liquid system may either separated or not separated.
Correspondingly the breathing ports 223 and 224 can be connected to the atmosphere by two ports or either one (e.g.
224) of two ports, when the other port is closed by a spare cap.

When the two heaters connected to the tank are both solar heat collector, the clapboard in the second space of water tank may not necessary. Then the top ends of two pipes are opened It can be understood by those skilled in the art that many common elements, for example, release valve, drain valve, protective anode and one or two electric heater(s) etc may also provided in the tank. Further more, a heat insulation layer and a crust outside of the tank wall may be provided.
All of these elements are shown in Fig. 1. Please refer to Figure 1.

Fig.6 is a schematic diagram illustrating the heat driven and self-circulation fluid heating and storage system employing a fluid heating and storage tank with double sidewalls and double bottom walls and two solar heat collectors. Even both solar heat collectors in Fig.6 are plate solar heat collectors. But each of them can be any kind of the solar heat collector, for example, the plate solar heat collector (with or without the heat tube), Vacuumed tube solar heat collector (with or without the heat tube) and U-shaped solar heat collector etc.

The solar heat collector 760 in Fig.6 has a secondary fluid inlet 7611 and outlet 7612. The first conduit 762 is connected its one end to inlet 422 of the tank and an opposite end to the outlet 7611 of the solar heat collector 761. The one end of second conduit 763 is connected to the outlet of the tank and the opposite end 7632 to the inlet of solar heat collector 760. The second solar heat collector 780 has similar connection arrangement.

Based on the application requirement, two couple inlet and outlet, 721/722 and 723/724 may be arranged at the sidewall in any angle from 90-180 degree. When the heat driven self-circulated liquid heating system is used as building elements, for example as a unit element of the roof, fence, veranda etc, the units with two solar heat collectors arranged in 180 degree are the plane unit of building walls, fences and verandas. The units with two solar heat collectors arranged in 90 degree are the corner units.

As a building component unit, the heat driven and self-circulating solar heating and storage system should be and can be a compacted component. In Fig. 6, when the solar heat collectors are moved close to the fluid heating and storage tank and make the solar heat collector's sizes larger, a compacted solar heating and storage system will be find.

Similar to those shown in Fig. 5, each of the two couple of inletioutlet ports is in a plumb line.
However, the angle of the solar heat collector may be oriented to an obliquity (i.e. not 90 degree) angle to the surface of the earth. Even if the inlet and out ports are in a plumb line, we still can adjust the arrangement of connecting conduits 762, 763,782and 783 to let the solar heat collector to be at an obliquity angle (not 90 degree) to the surface of the earth for receiving a point-black amount of sun light, It is also possible to arrange the entire unit of the solar heat collector and the tank to stay at an oblique angle to the earth. In this case the tank is catty-cornered. To protect the fall, the support of the system needs a special design.

After installation, the heat driven self-circulating solar heating and storage system 90 comes into being two fluidly separated but heat connected liquid spaces. The first space is the interior container of tank 70 which may be filled with the liquid to be heated e.g.
water, air or other fluids. The second space is formed by the interlayer 719, two conflux tubes of the two solar heat collectors, connecting conduits and the inner space of the apparatus for fluid condensing and reclaiming 51. This close-loop system connects to the atmosphere indirectly through the U-shaped tube 63. After the system is installed, the system will be filled with the heat conductive liquid, e.g. water or glycol. The liquid level in the tank will be lower than the breathing fitting.
When the sunlight irradiation heats the liquid in the solar heat collectors 760 and 780, the liquid in the conflux tubes 761 and 781 (within the heat insulation which is not shown in the Figure) is heated and tends to flow upwardly. The heated liquid flows through the connecting conduit 762 into the interlayer 719, and the heated liquid transfers its heat to the liquid in the tank through the sidewall and bottom wall of the interior container. Then the liquid temperature drops and the volume of the liquid also drops too. Through the outlet 724 and the conduit pipe 763, the cooled liquid flows back into solar heat collector 760 again for being heated. This processing continues in circles to heat the water in the tank by the solar heater. In this process, the solar heat is the only energy source to drive the circulating liquid and to complete the energy exchange.
Therefore, no other energy source, e.g. electric power, is required except the solar heat. In this process, when the sunlight is stronger, the heat circulation will be faster, whereas the heat circulating is slower, when the sunlight is weaker. When there is no sunlight, the heat circulating will terminate completely, It is not necessary to provide additional controller for controlling the liquid circulation. This head driven system has the functions of self-driven, self-control and self-circulating.

When the system is in operation, the breathing port 725 serves several important functions.
First it releases the pressure in the system caused by the heated liquid expansion for keeping the system pressure closes to the atmospheric pressure. It also provides a space for the liquid's breathing (namely, expansion and contraction) so as to facilitate the self-circulating operation.
When the heater is in operation, the heated liquid causes some liquid and vapor to flow into the container 51. The part of the vapor is cooled and condensed in the container 51, and then is returned to the heat exchanger. Some vapor may escape into the U-Shaped tube and then change into liquid, which will stay in the lower part of the tube. The gathered liquid in the tube blocks the further escape of vapor and would enhance further vapor to condense in the tube. When the heater stops working, the liquid in the container 51 and interlayer 719 cools down and contracts, so that the system generates a negative pressure to reclaim all the liquid gathered in the U-shaped tube to be drawn back into the heat exchanger. Even though the space storing the heat liquid is connected to the atmosphere directly or indirectly, the system working temperature is high, but the loss of the secondary liquid through vaporizing is not significant.
Accordingly the system operates continuously and safely.

For the space or other reasons, sometimes the solar heating system may be equipped with single solar heat collector only. In this case, the solar heat collector 780 may be removed and the spare inlet and outlet ports 421 and 423 are closed as shown in Fig.5. In another alternative, we can also replace the single solar heat collector by another type of heater operated with another energy source.

Based on the above-mentioned description, the tank in Fig.5 and Fig. 6 can be replaced by a tank with double layers of sidewalls or double layers of bottom walls.

Fig. 7 illustrates a heat driven self-circulating liquid heating and storage system 11 using a tank with double layer sidewalls and bottom walls. Comparing to Fig. 5, a solar hear collector 760 and a other energy source heater. The system illustrated shows a nature gas heater.

The tank 10, solar heat collector 760 and the connections between it and the tank are the same as shown in Fig.6. Here the nature gas heater 1100 is a central vacant cylinder (or other shaped e.g.
taper, square etc) metal (or ceramic etc) tank. There is a second liquid inlet 1106 provided at the bottom wall and a conduit connects the inlet with an outlet 124. At the upper (or top) sidewall there is a secondary fluid outlet 1105, which is connected to an inlet 123 of the tank through conduit 1107. A valve 1109 mounted in series to the tube 1107 is operative for turning off the gas supply when the heater is out of service. A similar valve may also be connected to the bottom conduit for the same purpose. The cover 1113 is for sheltering from the spark occurring in the heater.

The gas heater 1100 has a outer wall 1101 and a interior 1102 and heat insulation 1103 (not show in the figure). The secondary fluid is stored in the space enclosed by interior and outer walls, top and bottoms caps. The interior chamber 1104 has a gas burner 1110 which is supplied the gas by gas pipe 1111. There is a control valve 1112 for adjusting the gas supply.

When the system is in operation, the nature gas burns in the chamber 1104 of the heater to heat the inside wall 1102, thus the liquid, of the heater 1100 (there may be protective coat for heat insulation and corrosion protection). The heated liquid passes through the outlet 1105 and conduit 1107 to reach in the interlayer 119 of the tank. After the secondary liquid has transferred the heat to the water in the tank, the secondary liquid returns to the heater 1100 through the outlet of the tank. This processing is similar to the solar heat collector.

For a heat driven self-circulating fluid heating and storage system with a solar heat collector and another heater having another energy source, its operation is similar to that mentioned in the system with two solar heat collectors.

Even though the second heater shown in Gig. 7 is a nature gas heater, it can also be any alternative kind of non-solar heaters, e.g. fossil fuel (e.g. coal) heater, biomass energy heater, (including biomass gasification heater), nature gas, earth energy and air energy heater. The differences of this kind of the liquid heater is that the heating liquid storage space of this kind of heater is much smaller than any other kind of liquid heater. For example, one metal tube can be the storage container of the liquid to be heated in the heater. For the reason such as heat insulation and corrosion protection e.g. a firebrick or a ceramic protective layer may be provided.
Further more, this heater can be a heater of earth or air heat energy. Because these kinds of the heaters usually need the forced circulation, so the heaters need a separator (e.g. separator 207 in Fig.2) to separate the liquid into two sub-systems. In this case, only the sub-system connected to the solar heat collector has a breathing port. Another sub-system either has no breathing port or the port is closed with a spare cap.

Fig. 8 illustrates the heat driven self-circulating fluid heating and storage system 130 with a heat appliance (here is a radiator). The system includes a solar heater 760, a radiator and a liquid heating and storage tank 10 with double sidewalls and double bottom walls. In Fig. 8, the tank 10 and radiator and their connections are same as the embodiment shown in Fig.7.
The radiator includes a fin pipe 771 (it also can be a coil tube, helix tube, straight tube or a flat heat exchanger etc). Two pipes connect inlet 773 and outlet 774 of the radiator to the inlet 123 and the outlet 124 of the tank respectively. Two valves 777 and 778 are for separating the radiator with the tank when necessary.

Solar heat collector 760 receives solar energy and transfers it to the tank 10, so the temperature in the tank is higher than the temperature of the surrounding air. When heated air is required, the valve 777 and 778 of the tank are opened, so that the hot water circulates into valve 777 and go through fin tube 771 to emit warm air there from. After the emission of warm air, the cold water then goes through valve 778 to returns to the bottom of the tank 10. In order to increase the amount of heated air generating and to send the air to a planned direction, a cover 772 with an active window 770 may be provided. (as shown in the figure 8, the window is opened upwardly. The cover 772 has an inlet 779 for the air to be heated. In fact the direction of the window can be varied. One or more fans may be provided in the cover to speed up the heat pervasion from the fin tube. ( the fans did not show in the figure). If a canal is added to the window of cover 772, the heated air can be transferred to a desire location ( the canal did not show in the figure).

It can be note that the fitting 123 of the tank is an inlet when it is connected to a heater, but when it is connected to a radiator, it becomes an outlet, while the fitting 124 is an outlet when it is connected to a heater, but it becomes an inlet when it is connected to a radiator,.

It is also possible to install the radiator or other heat appliances in a heat driven and self-circulating system with two solar heat collectors or with one solar hear and one other heat source.
In this case, the fluid heating and storage tank need three couple inlets and outlets.

While the present invention has been shown and described in the preferred embodiments thereof, it will be apparent that various modifications can be made therein without departing from the spirit or essential attributes thereof, and it is desired therefore that only such limitations be placed thereon as are imposed by the appended claims.
