Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an embodiment of a heating system of the present invention, and fig. 2 is a schematic structural diagram of an embodiment of an energy conversion device and a heating device of the present invention.

In an embodiment, the heating system comprises a heating apparatus 10, an energy conversion apparatus 20 and a control apparatus 30. The heating apparatus 10 is connected to the energy conversion apparatus 20. The heat supply network water, which exchanges heat with the heat exchange steam, can flow from the energy conversion apparatus 20 to the heat supply apparatus 10 to realize heat supply by the heat supply apparatus 10. The control device 30 is capable of controlling the operation of the energy conversion device 20. The control device 30 is connected to the energy conversion device 20, and the two may be connected by a communication connection, an electrical connection, or the like, which is not limited herein. The control device 30 may be a control cabinet, a mobile terminal such as a mobile phone, and the like, which is not limited herein.

The heating device 10 may be a heating radiator, a floor heating system, or the like, which is not limited herein.

The energy conversion device of the present invention is illustrated below by way of example. It should be noted that, the utility model discloses energy conversion equipment is not restricted to being applied to heating system, can also be applied to industrial production etc. and is not repeated here.

Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of the energy conversion apparatus of the present invention.

In one embodiment, the energy conversion apparatus includes a housing assembly 21, a heat exchange assembly 22, a conduit assembly 23, and a water refill assembly 24.

The housing assembly 21 is provided with a storage cylinder 211, an electrode cylinder 212, and a discharge valve 213. The storage cylinder 211 is used for storing the heating medium and supplementing the heating medium to the electrode cylinder 212; the heating medium may be a mixture of water and an electrolyte, and is not limited herein. The electrode cartridge 212 is used to heat the contained heating medium to form heat exchange vapor. As the heating medium is heated in the electrode cylinder 212 to form the heat exchange steam, the pressure in the housing assembly 21 may increase, and for this reason, the exhaust valve 213 can exhaust a portion of the heat exchange steam to adjust the pressure in the housing assembly 21, thereby improving the safety of the energy conversion device.

The heat exchange assembly 22 is disposed in the casing assembly 21, and has a flowing heat supply network water therein, which can exchange heat with the heat exchange steam. In other words, the heat exchange steam heated by the electrode cylinder 212 has a temperature higher than that of the grid water, and can conduct heat to the grid water, so that the grid water is heated up, and thus the heat supply device 10 can release heat to the environment when the grid water flows into the heat supply device 10 (as shown in fig. 1).

The pipe assembly 23 is connected to the electrode cartridge 212 and the storage cartridge 211, respectively, to allow a heating medium to flow therebetween, thereby adjusting the amount of heating. That is, the heating medium can flow from the storage cylinder 211 to the electrode cylinder 212 through the manifold assembly 23 to increase the heating capacity of the energy conversion device. The heating medium can also flow from the electrode cartridge 212 through the manifold assembly 23 to the storage cartridge 211 to reduce the amount of heating of the energy conversion device.

The water replenishing assembly 24 is connected with the storage cylinder 211 and the heat exchange assembly 22 respectively. Partial heat supply network water flows through the water supplementing assembly 24 from the heat exchange assembly 22, enters the shell assembly 21, can supplement heat exchange steam exhausted from the exhaust valve 213, reduces the risk that heat medium is insufficient in the energy conversion equipment, realizes the internal recycling of the heat medium in the energy conversion equipment, can reduce the tedious operation of supplementing the heat medium through an additional heat medium supplementing system, simplifies the operation mode of the energy equipment, can enrich the functionality of the energy conversion equipment, and simplifies the structure of the energy conversion equipment.

Therefore, in the embodiment, part of the heat supply network water is supplemented into the storage cylinder 211 through the water supplementing assembly 24 so as to supplement the heat exchange steam overflowing due to the large internal pressure of the energy conversion equipment, and the operation mode of the energy equipment can be simplified. Less heat exchange steam overflows from the energy conversion equipment, less heat supply network water needs to be supplemented into the storage cylinder 211 from the heat exchange assembly 22, and the heat supply effect of the heat supply system is slightly influenced.

Please continue to refer to fig. 3. In one embodiment, the pipe assembly 23 includes a first water replenishing pipe 231 and a second water replenishing pipe 232. The refill assembly 24 includes a filter 241.

The first water replenishing pipeline 231 is connected with the heat exchange component 22 and the filtering piece 241, and the second water replenishing pipeline 232 is connected with the filtering piece 241 and the storage cylinder 211. The heat supply network water flows to the filtering piece 241 from the heat exchange component 22 through the first water replenishing pipeline 231, the filtering piece 241 can filter the heat supply network water, the filtered heat supply network water flows to the storage cylinder 211 through the second water replenishing pipeline 232, and the filtered heat supply network water can serve as heat medium in the storage cylinder 211, so that the risk of insufficient total amount of the heat medium in the energy conversion equipment is reduced.

Further, the pipeline assembly 23 further includes a first water replenishing switch and a second water replenishing switch (not shown), which are respectively disposed on the first water replenishing pipeline and the second water replenishing pipeline. The energy conversion apparatus further comprises a liquid level monitoring member (not shown) disposed in the housing assembly 21. That is, the fluid level monitoring member may be disposed within the storage barrel 211 and/or within the electrode barrel 212.

The first water replenishing switch member, the second water replenishing switch member and the liquid level monitoring member are respectively connected to an external control device 30 (shown in fig. 1). The liquid level monitoring piece can monitor the residual amount of the heating medium in the shell assembly 21 and feed back the residual amount of the heating medium to the control device 30, and the control device 30 controls whether the first water supplementing switch piece and the second water supplementing switch piece are conducted or not based on the received heating medium residual amount information.

When the liquid level monitoring piece detects that the liquid level of the heating medium in the shell assembly 21 is smaller than or equal to the first liquid level value, the control device controls the first water supplementing switch piece to be conducted with the second water supplementing switch piece so as to allow the heat supply network water to be supplemented into the shell assembly 21. When the liquid level monitoring piece detects that the liquid level of the heating medium in the shell assembly is larger than or equal to the second liquid level value, the control device controls the first water supplementing switch piece and the second water supplementing switch piece to be turned off, and the heat supply network water is not required to be supplemented into the shell assembly 21. Wherein the first liquid level value is smaller than the second liquid level value.

For example, the first level value may be 1000mm, and the second level value may be 1600mm, which may be adjusted according to the volume and height of the housing assembly in practical applications, and is not limited herein.

In an alternative embodiment, the overflow rate of the heating medium overflowing from the exhaust valve 213 may be calculated in advance, and the network water may be controlled to be continuously supplied to the housing assembly at the same rate, which is not limited herein.

Please continue to refer to fig. 3. In one embodiment, the water replenishing assembly 24 further comprises a heating element 242, and the heating element 242 is disposed between the filtering element 241 and the second water replenishing pipe 232. The heating element 242 can heat the heat supply network water filtered by the filtering element 241 to form heating steam, and the heating steam is introduced into the storage cylinder 211 through the second water replenishing pipeline 232 and condensed to form a heating medium so as to further purify the heat supply network water. When the heat supply network water forms heating steam, impurities mixed in the heat supply network water are precipitated at the bottom, and the heating steam is upwards diffused to carry out the storage cylinder 211, which is equivalent to further filtering the heat supply network water.

Moreover, when the heat supply network water is directly injected into the storage cylinder 211 under the influence of the pressure change in the capacity conversion device, the pressure in the storage cylinder 211 may be large, and the heat supply network water may not be replenished into the storage cylinder 211. And the heating steam formed by heating the heat supply network water is easier to enter the storage cylinder 211 compared with the heat supply network water.

Specifically, the heat supply network water can be directly supplemented into the storage cylinder 211, and the heat medium is supplemented into the electrode cylinder 212 from the storage cylinder 211; alternatively, the heating steam entering the storage cylinder 211 is convected and further flows up to the heat exchange assembly 22, and then flows back to the electrode cylinder 212 through the heat exchange assembly 22, and the specific flow back is the same as the flow back of the heating medium steam to the electrode cylinder 212, which will be described in detail later.

Please continue to refer to fig. 1 and 3. In one embodiment, the energy conversion device includes a pressure monitoring member 26, and the pressure monitoring member 26 is disposed in the housing assembly 21 and is capable of monitoring the pressure inside the housing assembly 21, and thus the pressure inside the energy conversion device. The pressure monitoring member 26 is connected to the control device 30 to feed back the monitored pressure to the control device 30.

The circuit assembly 23 includes a first heating medium circuit 233 and a second heating medium circuit 234, both of which connect the electrode cartridge 212 and the storage cartridge 211. The first heating medium circuit 233 may direct the heating medium from the electrode cartridge 212 to the storage cartridge 211, and the second heating medium circuit 234 may reverse the heating medium from the storage cartridge 211 to the electrode cartridge 212.

The first and second heating medium pipes 233 and 234 are provided with first and second heating medium switches 2331 and 2341, respectively. The first and second heat medium switching members 2331 and 2341 are connected to the control unit 30, respectively, and the control unit 30 controls whether the first heat medium switching member 2331 is turned on or off to control whether the heat medium is allowed to flow from the cartridge 211 to the electrode cartridge 212, and the control unit 30 controls whether the second heat medium switching member 2341 is turned on or off to control whether the heat medium is allowed to flow from the electrode cartridge 212 to the cartridge 211.

Alternatively, the first heating medium line 233 may be communicated with the communication line 235, which means that the heating medium of the storage cylinder 211 flows through the first heating medium line 233, is pumped into the communication line 235 through the first heating medium switch 2331, and then flows into the electrode cylinder 212, simplifying the line structure of the energy conversion device.

Still further, a liquid level monitor is disposed in the electrode cylinder 212, so that when the energy conversion device is started, the control device 30 controls the first heating medium switch 2331 to be turned on, and the heating medium in the storage cylinder 211 is replenished into the electrode cylinder 212.

During operation of the energy conversion device at steady power, the fluid level in the housing assembly remains substantially constant, storage cartridge 211 may not be replenished with heating medium into electrode cartridge 212, and first heating medium switch 2331 remains off, i.e., the first heating medium line remains off, to prevent heating medium from flowing from storage cartridge 211 to electrode cartridge 212.

As mentioned above, when the heating amount of the energy conversion device is changed, it is general to change the remaining amount of the heating medium in the electrode cartridge 212. The heating amount can be increased when the heating medium flows into the electrode cylinder 212; the heating amount can be reduced when the heating medium flows out of the electrode cylinder 212.

It is considered that when the heating amount (such as heating power) of the energy conversion apparatus currently existing is increased, the load change causes the gas inside the energy conversion apparatus to fluctuate drastically. The pressure inside the energy conversion device rises rapidly, and when the pressure limited by the exhaust valve 213 is reached, the exhaust valve 213 is opened to discharge the heat exchange steam, so that the heat medium inside the energy conversion device is lost. At this time, a large amount of heat medium is usually required to be additionally supplemented, which influences the long-term stable operation of the equipment.

For this reason, in the present embodiment, when the pressure monitoring part 26 monitors that the pressure is greater than or equal to the first preset value, the control device 30 controls the first heating medium switch 2331 to turn off the first heating medium line 233. When the monitored pressure is less than or equal to the second preset value, the control device 30 controls the first heating medium switch 2331 to turn on the first heating medium line 233.

Therefore, the pressure of the energy conversion equipment can be kept in a micro-positive pressure state during operation, namely, the pressure is slightly higher than the standard atmospheric pressure, so that the temperature of a heating medium in the energy conversion equipment is slightly higher than the standard atmospheric pressure, for example, the temperature of water can exceed 100 ℃, and meanwhile, the micro-positive pressure state is beneficial to ensuring the safety of the energy conversion equipment.

The first preset value is greater than or equal to the second preset value, and the specific difference between the first preset value and the second preset value can be limited according to the actual application scene.

For example, the first preset value and the second preset value may be gauge pressure or absolute pressure, and are not limited herein. Gauge pressure refers to the number of total absolute pressures above ambient atmospheric pressure or the fraction of the pressure in the liquid that is above atmospheric pressure at some point.

Taking the first preset value and the second preset value as gauge pressure as an example, the first preset value can be 45kPa (i.e. the absolute pressure is 146.32545 kPa), and the second preset value can be 20kPa (i.e. the absolute pressure is 121.32545 kPa). The above values are for illustration, and are not intended to limit the specific data of the first preset value and the second preset value in the present invention. That is, when the heat medium is supplied into the electrode cylinder 212, whether the heat medium is supplied or not can be controlled in combination with the pressure information, the supply of the heat medium is suspended when the monitored pressure is out of the safety range, and the supply of the heat medium is resumed when the pressure is restored to the safety range. If the monitored pressure is always less than or equal to the first predetermined value, the control device controls the first heating medium switch 2331 to replenish the heating medium at a predetermined liquid level ramp rate in combination with the liquid level information monitored by the liquid level monitor until the target power/shell assembly target liquid level of the energy conversion device is reached.

Further, the exhaust valve 213 may also be connected to the control device 30. When the monitored pressure is greater than or equal to a third preset value, the control device controls the exhaust valve 213 to be opened to allow the gas in the housing assembly 21 to escape, so that the pressure in the energy conversion device is within a safe range; when the monitored pressure is less than or equal to the first preset value, the control apparatus controls the exhaust valve 213 to be closed. Taking the third preset value as an example of gauge pressure, the third preset value may be 50kPa (i.e. an absolute pressure of 151.32545 kPa).

Referring to fig. 3 and 4 in combination, fig. 4 is a structural schematic diagram of the energy conversion apparatus shown in fig. 3 in a related direction.

In one embodiment, the opening direction a of the electrode cartridge 212 is the same as the opening direction B of the storage cartridge 211.

Thus, the electrode cylinder 212 and the storage cylinder 211 may be arranged in parallel to reduce the height of the energy conversion apparatus and improve the compactness of the energy conversion apparatus. And after the height of the energy conversion equipment is reduced, the application scenes of the energy conversion equipment are enriched.

Further, the relative direction C between the electrode cylinder 212 and the storage cylinder 211 can be parallel to the extending direction D of the heat exchange assembly 22, and can also be perpendicular to the relative direction E between the heat exchange assembly 22 and the storage cylinder 211 and the electrode cylinder 212, so as to further improve the compactness of the energy conversion device.

Please continue to refer to fig. 3. In one embodiment, the housing assembly 21 includes a connection housing 214, and the connection housing 214 is disposed between the heat exchange assembly 22 and the electrode cartridge 212. The connection housing 214 is provided with a reflow hole 2141. The pipe assembly 23 includes a connecting pipe 235 connecting the electrode cartridge 212 and the reflow hole 2141.

After heat exchange is carried out between the heat exchange steam and the heat supply network water of the heat exchange assembly 22, the heat medium formed by condensation due to heat conduction to the heat supply network water drops to the connecting shell 214 under the action of gravity and flows into the communicating pipeline 235 through the backflow hole 2141, and flows back to the electrode cylinder 212 through the communicating pipeline 235 based on the liquid level difference principle to be used for forming the heat exchange steam again in subsequent heating, so that the heat medium is recycled.

Please continue to refer to fig. 3. In an embodiment, the energy conversion device further includes an electrical parameter detection component 27, and the electrical parameter detection component 27 is disposed on a metal portion of the housing component 21 and is capable of detecting a ground resistance and/or a voltage to ground to determine whether the energy conversion device is abnormal, so as to improve the reliability of the energy conversion device.

The electrodes 2121 are uniformly distributed around the circumference of the electrode cylinder 212, i.e., the electrodes 2121 are spaced 120 ° apart. The three-phase power of the external power supply is connected to the three-phase electrodes 2121, and the heating medium can be used as a load resistor.

Alternatively, please refer to fig. 5, fig. 5 is a schematic structural diagram of an electrode cylinder and an embodiment of an electrode according to the present invention. An embodiment in which the number of electrodes 2121 in the electrode cartridge 212 is six, i.e., three-phase six-stage, is illustrated in fig. 5 by way of example.

Wherein, X1, X2 and X3 are respectively used for representing different phase electrodes, the same phase electrodes are connected with the same phase circuit, and the different phase electrodes mutually form an angle of 120 degrees.
