Description

TANK AND SYSTEM OF HEATING AND STORAGE OF FLUID OF SELF-CIRCULATED FLUID AND OF HEAT DRIVEN FIELD OF THE INVENTION The present description relates to storage tanks and fluid heating, especially relates to storage tanks and heating of fluids having double walls. It is also related to storage and heating systems of circulated and circulated heat fluids used by tanks and that have multiple sources of energy, especially solar heat collectors.

BACKGROUND OF THE INVENTION Currently, solar heat is becoming increasingly popular. To reduce physical equipment, software, installation, operation and maintenance costs, the applicant of this application describes a self-driven pump and hot fluid drive technology in Patent Applications No. CA2628605 and PCT 2009000531. In another application Patent CA2678584, the applicant of this application further describes various hot fluid and self-circulating conduction systems. All these systems need the basic equipment-heating tank and fluid storage. The tanks described in the above patent applications are different in construction in the above systems. This is not convenient for manufacturing and installation. One purpose of this application is to develop tanks for solar heating systems and circulating auto heat storage storage through a standardized and modularized manufacturing.

Solar energy varies in different seasons, locations and climates. Thus solar energy in solar heat collected in a solar heating system is not constant. It is expected by solar energy customers that a fluid fluid storage and heating 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 into buildings in recent decades. The technology of driving hot fluid and self circulation has made it much easier to integrate the solar heating system with the buildings. It is the third purpose of this invention to return to the solar heating systems a part of the integral structure of the modular units of the building.

Heating and fluid storage tanks with double walls are currently known. However, existing tanks can not be used for storage systems and heating of heat fluid driven and self-circulating when the tank is not located above the heater. Existing tanks for multiple energy sources can also not be used in a heat conduction and self-circulation system.

The fluid that vaporizes and escapes from the heating fluid is a risk for the continuous safety operation of a system and for storage and heating of heat conduction fluid and self circulation. Some solutions to solve such problem have been developed in the previous patent applications. This description provides an improved and more efficient fluid vapor condensing and recovery apparatus.

It has an inner container 111 comprising a side wall 112, an upper lid 113, a lower lid 114 for forming 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 in the upper part (this can be in the side wall as well), a drain valve 135 and an electric power heater 136. Of course, two electric power heaters can be provided if necessary.

A second column (or other shape) shaped layer wall 115 is disposed outside the inner container 111. Its upper cover (here is a ring) 117 is mounted on the side wall of the tank and its bottom 118 is below the edge lower 116 of the inner container. So that the inner container 119 or the second space is enclosed by the lower lid and the side wall 112 of the inner container, the outer wall 115, the ring 117 and the lower lid 118. The second container is for the second fluid, the which is a liquid for example water or ethylene glycol etc.

On the second wall the entrances 121 and 123, the exits 122 and 124 are arranged for a secondary fluid. The outlets 122 and 124 are not higher than the outlets 121 and 123 to ensure self-circulation of the heated liquid. In the lower lid of the second wall there may be some braces 128 and 129 to support the inner container for the second wall.

The heat of the container 119 is transferred to the fluid in the inner container 111 through the side wall 112 and the lower lid 114. Thus the material of the inner container needs to be of a heat conducting material eg copper, aluminum, stainless steel or steel enamel glass or porcelain.

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

The second fluid condensing and recovery apparatus 51 is connected to the assembly 126. Figure 3 is a schematic diagram illustrating the apparatus 51.

The apparatus 51 is an airtight container. This has a top 511 and a bottom 512 and side wall 513. An inlet pipe 52 having its end extending upwardly from the bottom in the container and ted to the bottom of the container. In the Figure. 3, the inlet pipe 52 is a hollow pin. Its opposite end 522 can be rotated directly inside the breathing assembly in the upper part of the tank.

A U-shaped flex pipe 53 (may be many other forms of pipe, for example in the form of W etc.) extends its end 531 from the side wall of the container 51 into the container and below the stop wall 511. Its upper end is separated from the upper wall. The other parts, including the lower part of the pipe, are located outside the tank. The pipe extends its opposite end downwards first and then upwards. So that the opposite end of the pipe 53 is directed upwards and its lower part 533 is located near the bottom of the container.

With reference to Figure 4, an alternative fluid vapor condensation and recovery apparatus is illustrated. Except for the U-shaped tube 63, other parts of this second embodiment are similar to the apparatus 51 described above. The reference numbers in this Figure are changed from the first digit 5 to 6. Otherwise the construction is similar to the apparatus 51 described above.

A U-shaped tube 63 extends its end 634 from the bottom 612 of the container 61 within the container and below the top wall 611. There is a clearance between the end and the top wall. In Figure 6, the apparatus provides breathing for the liquid due to extension and contraction. A small at of condensed liquid is retained in the lower part of the apparatus 61, which further avoids vapor escaping into the atmosphere through the U-shaped tube 63.

Figure 4 is a schematic diagram illustrating another class of apparatus for recovering and condensing liquid vapor.

The feature of the container mentioned above is to condense the vapor of liquid in the container and allow the condensed fluid to return to the heater. Generally, any interior wall of a vessel at a temperature less than 100 degrees can cause steam to condense. Generally, any metal, for example plastic, glass or polymer material, can be used to make the container. When the system and the ambient temperature is high, to accelerate the condensation process, some condensation pieces may be installed in the container (not shown in Figures 3 and 4). The flex pipe 63 also needs to cause the steam to condense in the tube.

In addition, in the U-shaped bottom part of the pipeline a little condensate liquid can be stored temporarily to block the escape of escaped steam. The bending pipe can be made with many different materials such as glass, metal, plastic, polymeric material etc. The shapes of the pipe are flexible, for example U-shaped, W-shaped or the like in which the lower part of the pipe can store some condensed liquid. Transparent pipes can be used to provide visible monitoring of condensed liquid.

One of the main problems in operating a heating tank and storage of circulated auto driven heat fluid such as the solar heating system is the vaporizer of fluid and the vapor escaping through the breathing port. It may result in a failure of the system operation. The use of the apparatus introduced above to condense and recover fluids solves this problem completely. Generally the containers of the apparatus are made with materials with transparency, for example transparent glass, plastic or polymeric materials, so the liquid level of the heat exchanger can be monitored visually, and more liquid can be added through the port of respiration if it is necessary.

When the position of the secondary bottom wall moves upwardly until it is connected to the edge of the first lower wall, the tank becomes a tank for heating and storing fluid with double side walls. Figure 5 also illustrates the operating situation of a tank with double side walls but without the double bottom wall.

There are two spare bolt caps to close the unused inlet and outlet and a spare bolt cover to close the unused breathing assembly. If necessary, all breathing ports can be closed. In this case, the tank can be used as a regular tank with the heat exchanger or be used with the self-powered pump or an electric pump.

Figure 2 is a schematic diagram illustrating the fluid storage and storage tank with double bottom walls, which is a water tank with column 20. The side wall with column 201, the coronary top cap 202 and the bottom cap 203 form a closed space 21 for the main fluid, which may be water. The side wall 201 extends from the lower edge 206 and forms a new extended side wall 204. The side wall 204 together with the first lower wall 203 and the second lower wall 205 enclose a second space 22 for the secondary fluid which may be water or an antifreeze for example glycol etc. In the side wall 201 of the tank, there are two pipes 208 and 209 arranged at 180 ° in relation to one another. Their lower ends 221 and 222 respectively extended through the side wall and into the second space 22. The other ends 223 and 224 extend upwardly around the side wall and are connected with 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 to connect with the secondary fluid heater. The two tubes 208 and 209 can be other types of channels. For example, there may be two grooves to fit on the surface of the side wall. One end of these tubes extends into the second space and the opposite end extends towards the top of the tank. For corrosion protection purposes, the interior of the channels needs to be veneered with glass enamel or porcelain. Alternatively, the tubes or channels can be arranged inside the tanks. The ends of the pipes or channels can also be located in some locations below the top of the tank. The angle of the two pipes 208 and 209 on the side wall of the tank can also be located at 90 degrees or other selected angles.

On the side wall near the bottom, the exits 212 and 214 of the secondary fluid are arranged. Figure 5 also shows that the second tank space is separated into two left and right sub-spaces by a board 207. The fluids in these two sub-spaces are isolated. There are two separate sub-liquid systems in the second space. This type of system is used for two types of heaters on both sides of the tank. Especially it is used for the system where a heater requires forced circulation. For example, the first heater is a solar heater and the second heater is another heater of energy which needs a forced circulation, for example the energy of the earth or energy of the air. To use some source of energy r, for example biomass energy, gas energy and fossil fuel energy, if there is no need for forced circulation, the secondary liquid system can be either separated or not separated.

Correspondingly the breathing ports 223 and 224 can be connected to the atmosphere by means of two ports or any (for example 224) of the two ports, when the other port is closed by a spare cover.

When the two heaters connected to the tank are both a solar heat collector, the splint in the second space of the water tank may not be necessary. Then the upper ends of the two pipes open. This can be understood by persons skilled in the art to have many common elements, for example, the release valve, drain valve, protective anode and one or two electric heater (s) etc. They can also be conditioned in the tank. In addition, a layer of heat insulation and an outer shell of the tank wall can be provided. All of these elements are shown in the Figure. 1. Please refer to Figure 1.

Figure 6 is a schematic diagram illustrating the heating and storage system of conducted heat and self-circulating heat that employs a tank for heating and storing fluid with double side walls and double bottom walls and two solar heat collectors. Even both solar heat collectors in Figure 6 are plate solar heat collectors. But each of them can be any type of solar heat collector, for example, the plate solar heat collector (with or without the heat tube), the vacuum tube solar heat collector (with or without the tube of heat) and the U-shaped solar heat collector, etc.

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

Based on the application requirement, two inlet and outlet couplings, 721/722 and 723/724 can be fixed to the side wall at any angle from 90-180 degrees. When the self-circulating heat conduction fluid heating system is used as building elements, for example as a unitary element of the roof, fence, gazebo etc., the units with two solar heat collectors arranged in 180 degrees are the flat unit of building walls, fences and lookouts. The units with two solar heat collectors arranged at 90 degrees are the corner units.

As a building component unit, the heating and solar storage system of heat conduction and self-circulating must be and can be a compacted component. In the Figure. 6, when the solar heat collectors move near the heating and fluid storage tank and make the larger sizes of the solar heat collector, you will find a condensed compacted solar heating and storage system.

Similar to those shown in Figure 5, each of the two input / output port couplings is in a plumbing line. However, the angle of the solar heat collector can be oriented at an oblique angle (ie, it is not a 90 degree angle) to the ground surface. Even if the input and output ports are on a pipeline, you can still adjust the arrangement of the connecting conduits 762, 763,782 and 783 to allow a solar heat collector to be at an oblique angle (not 90). degrees) to the surface of the earth to receive a number of black-points of sunlight. It is also possible to fix the entire unit of the solar heat collector and the tank to remain at an oblique angle to the ground. In this case the tank is in opposite diagonals. To protect the fall, the system support needs a special design. After installation, the self-circulating solar heat conduction heating and storage system 90 emerges two liquid spaces that are fluidly separated but thermally connected. The first space is the inner container of the tank 70 which can be filled with the liquid to be heated such as water, air or other fluids. The second space is formed by the intermediate layer 719, the two confluent tubes of the two solar heat collectors, the connection conduits and the interior space of the apparatus for condensing and recovering the fluid 51. This closed 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 conducting liquid, for example water or glycol. The level of liquid in the tank will be lower than the breathing assembly.

When the irradiation of the sunlight heats the liquid in the solar heat collectors 760 and 780, the liquid in the confluent tubes 761 and 781 (inside the heat insulation which is not shown in the Figure) is heated and tends to flow ascending 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 side wall and the lower wall of the inner container. Then the temperature of the liquid drops and the volume of the liquid also decreases. Through the outlet 724 and the conduit pipe 763, the cooled liquid flows back into the solar heat collector 760 again to be heated. This processing continues in circles to heat the water in the tank by the solar heater. In this process, solar heat is the only source of energy to conduct the circulating liquid and to complete the exchange of energy. Therefore, no other source of energy, for example electrical energy, is required except solar heat. In this process, when the sunlight is stronger, the circulation of heat will be faster, while the circulation of heat is slower, when the sunlight is weaker. When there is no sunlight, the circulation of heat will end completely. It is not necessary to provide additional control to control the circulation of liquid. This main driving system has the functions of self-driving, self-control and self-circulation. 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 expansion of heated liquid to maintain the system pressure close to atmospheric pressure. It also provides a space for the fluid to breathe (ie, an expansion and contraction) to facilitate self-circulation 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 returned to the heat exchanger. Some steam can escape into the U-shaped tube and then change into liquid, which will remain in the bottom of the tube. The liquid collected in the tube blocks the additional escape of steam and would further improve the steam to condense in the tube.

When the heater stops working, the liquid in the container 51 and the interlayer 719 cools and contracts, so that the system generates a negative pressure to recover all the liquid collected in the U-shaped tube to be sucked back inside. of the heat exchanger. Even when the space that stores the hot liquid is directly or indirectly connected to the atmosphere, the working temperature of the system is high, but the loss of the secondary fluid through vaporization is not significant. Therefore, the system works continuously and safely.

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

According to the above description, the tank in the Figure 5 and Figure 6 can be replaced by a tank with double layers of side walls or double layers of bottom walls.

Figure 7 illustrates a self-circulating heat conduction liquid heating and storage system using a tank 10 with double layer side walls and the bottom walls. In comparison with Figure 5, a solar heat collector 760 and a different energy source heater. The illustrated system shows a natural gas heater.

Tank 10, the solar heat collector 760 and the connections between it and the tank are the same as those shown in Figure 6. Here the natural gas heater 1100 is a central free cylindrical metal (or ceramic) tank ( or otherwise for example flared, square, etc.) (or ceramic etc.). There is a second liquid inlet 1106 provided in the bottom wall and a duct connects the inlet with an outlet 12. In the upper (or upper) side wall there is a secondary fluid outlet 1105, which is connected to an inlet 123 of the tank through the duct 1107. A valve 1109 mounted in series with the tube 1107 can be operated to shut off the gas source when the heater is out of service. A similar valve can also be connected to the lower conduit for the same purpose. Cover 1113 is to protect against a spark that occurs in the heater.

The gas heater 1100 has an outer wall 1101 and an interior 1102 and heat insulation 1103 (not shown in the Figure). The secondary fluid is stored in the space enclosed by the interior and exterior walls, the upper and lower covers. The inner chamber 1104 has a gas burner 1110 which is supplied with gas by the gas line 1111. There is a control valve 1112 for adjusting the gas source.

When the system is in operation, the natural gas is burned in the chamber 1104 of the heater to heat the inner wall 1102, thus the liquid, of the heater 1100 (there may be a protective coating for heat insulation and corrosion protection). The hot liquid passes through the outlet 1105 and the duct 1107 to reach 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 heating and storage system of self-circulated heat driven fluid with a solar heat collector and another heater that has another energy source, its operation is similar to that mentioned in the system with two solar heat collectors.

Although the second heater shown in Figure 7 is a natural gas heater, it can also be any alternative type of non-solar heaters, for example a fossil fuel heater (eg coal), biomass energy heater, ( including the biomass gasification heater), natural gas heater, ground energy and air power. The difference of this type of liquid heater is that the storage space of heating liquid of this type of heater is much smaller than any other type of liquid heater. For example, a metal tube may be the storage container for the liquid that will be heated in the heater. For a reason such as heat insulation and corrosion protection for example refractory brick or ceramic protective layer can be provided. In addition, this heater can be a heater of thermal energy from the ground or from the air. Because these types of heaters generally require forced circulation, the heaters require a separator (eg, separator 207 in Figure 2) to separate the liquid into two subsystems. In this case, only the subsystem connected to the solar heat collector has a breathing port. Another subsystem either has no breathing port or the port is closed with a spare cover.

Figure 8 illustrates the system of heating and storage of circulated self-circulated heat fluid 130 with a heating equipment (here is a radiator). The system includes a solar heater 760, a radiator and a liquid storage and heating tank 10 with double side walls and double bottom walls. In the Figure. 8, the tank 10 and the radiator and their connections are the same as the mode shown in Figure 7. The radiator includes a 771 fin pipe (it can also be a coil pipe, a propeller pipe, a straight pipe or a flat heat exchanger). etc.). Two pipes connect the inlet 773 and the outlet 774 of the radiator with 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.

The solar heat collector 760 receives solar energy and transfers it to tank 10, thus the temperature in the tank is higher than the temperature of the surrounding air. When heated air is required, valves 777 and 778 of the tank are opened, whereby hot water circulates within valve 777 and passes through tube 771 to emit hot air therefrom. After the emission of hot air, the cold water then runs through the valve 778 to return to the bottom of the tank 10. In order to increase the amount of heated air that is generated and send the air to a planned direction, it can a cover 772 with an active window 770 is provided (according to that shown in 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 can be provided on the deck to accelerate the pervasion of heat from the fin tube (the blades are not shown in the Figure). If a channel is added to the cover window 772, the heated air can be transferred to a desired location (the channel is not shown in the figure). It can be seen that the assembly 123 of the tank is an inlet when connected to a heater, but when connected to a radiator, it becomes an outlet, while assembly 124 is an outlet when connected to a heater, but it becomes an entrance when it is connected to a radiator.

It is also possible to install the radiator or other heat equipment in a system of heat driven and self-circulation with two solar heat collectors or with a solar heater and another heat source. In this case, the heating and fluid storage tank needs three input and output couplings.

While the present invention has been shown and described in the preferred embodiments thereof, it will be evident that various modifications may be made therein without departing from the spirit or essential attributes thereof, and it is therefore desired that only limitations be placed on it. on it according to what is established in the appended claims.
