Description

Energy conversion equipment and heating systems

technical field

The utility model relates to the technical field of boiler equipment, in particular to an energy conversion equipment and a heating system.

Background technique

The working principle of energy conversion equipment such as boilers is that the energy input to it can be chemical energy or electrical energy of fuel, and then can output steam, high-temperature water or organic heat carrier with certain heat energy.

The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator.

The heat medium is the carrier of heat in the heating system. The heat medium of the heating system should be determined based on comprehensive consideration of factors such as safety, sanitation, economy, building properties and regional heating conditions. Generally speaking, the main choice of heat medium is hot water or steam.

Boilers that provide hot water are called hot water boilers, which can be used mainly for domestic purposes or for industrial production. Boilers that provide steam are called steam boilers, often referred to as boilers for short, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.

However, when the working power of the existing boiler changes, due to the insufficient heat exchange of the internal heat medium, the pressure inside the boiler exceeds the limit, resulting in part of the steam formed by heating the heat medium, which will overflow through the exhaust valve of the boiler to ensure the internal pressure of the boiler. The pressure is within the safe range. If so, the heat medium in the boiler will be reduced. For this reason, existing boiler products generally need to be additionally equipped with a circulating water recovery system, resulting in poor functionality of the boiler and relatively large volume.

Please refer to Fig. 1 and Fig. 2, Fig. 1 is a schematic structural diagram of an embodiment of the heating system of the present invention, and Fig. 2 is a schematic structural diagram of an embodiment of the energy conversion equipment and heating equipment of the present invention.

The energy conversion equipment in the utility model is described as an example below. It should be noted that the energy conversion equipment of the present utility model is not limited to be used in heating systems, but can also be used in industrial production, etc., so it will not be repeated here.

Please refer to FIG. 3 . FIG. 3 is a schematic structural diagram of an embodiment of the energy conversion device of the present invention.

In one embodiment, the energy conversion device includes a housing component 21 , a heat exchange component 22 , a pipeline component 23 and a water supply component 24 .

The housing assembly 21 is provided with a storage cylinder 211 , an electrode cylinder 212 and an exhaust valve 213 . The storage cylinder 211 is used for storing the heat medium and replenishing the heat medium to the electrode cylinder 212 ; wherein, the heat medium may be a mixture of water and electrolyte, etc., and is not limited herein. The electrode cylinder 212 is used to heat the contained heat medium to form heat exchange steam. As the heat medium in the electrode cylinder 212 is heated to form heat exchange steam, the pressure in the shell assembly 21 may increase accordingly, so the exhaust valve 213 can discharge part of the heat exchange steam to adjust the pressure in the shell assembly 21 , to improve the safety of energy conversion equipment.

The heat exchanging component 22 is arranged on the shell component 21 , and there is flowing hot network water inside it, and the hot net water can exchange heat with the heat exchanging steam. In other words, the temperature of the heat exchange steam formed by heating the electrode cylinder 212 is higher than that of the heating network water, and can conduct heat to the heating network water, so that the heating network water heats up, so that when the heating network water flows into the heating equipment 10 (as shown in Figure 1 ), the heating device 10 can release heat to the surrounding environment.

The pipeline assembly 23 is respectively connected to the electrode cylinder 212 and the storage cylinder 211 to allow the heat medium to flow between the two, thereby adjusting the heating capacity. That is to say, the heat medium can flow from the storage cylinder 211 to the electrode cylinder 212 through the pipe assembly 23 to increase the heating capacity of the energy conversion device. The heat medium can also flow from the electrode cylinder 212 to the storage cylinder 211 through the pipeline assembly 23, so as to reduce the heating capacity of the energy conversion equipment.

The water supply assembly 24 is connected to the storage cylinder 211 and the heat exchange assembly 22 respectively. Part of the heating network water flows from the heat exchange component 22 through the water replenishment component 24 and passes into the shell component 21, which can supplement the heat exchange steam discharged from the exhaust valve 213, reduce the risk of insufficient heat medium in the energy conversion equipment, and realize the heat medium in the The internal recycling of the energy conversion equipment can also reduce the tedious operation of supplementing the heat medium through an additional supplementary heat medium system, simplify the operation mode of the energy equipment, enrich the functionality of the energy conversion equipment, and simplify the structure of the energy conversion equipment.

It can be seen that, in this embodiment, part of the hot grid water is replenished into the storage cylinder 211 through the water supply component 24 to replenish the heat exchange steam overflowed by the energy conversion equipment due to high internal pressure, which can simplify the operation mode of the energy equipment. The heat exchange steam overflowing the energy conversion equipment is less, and the heat network water that needs to be supplemented into the storage cylinder 211 from the heat exchange component 22 is also less, which has a weak impact on the heating effect of the heating system.

Please continue with Figure 3. In one embodiment, the pipeline assembly 23 includes a first water supply pipeline 231 and a second water supply pipeline 232 . The water supply assembly 24 includes a filter element 241 .

The first water supply pipeline 231 is connected to the heat exchange assembly 22 and the filter element 241 , and the second water supply pipeline 232 is connected to the filter element 241 and the storage cylinder 211 . The heating network water flows from the heat exchange assembly 22 to the filter element 241 through the first replenishing water pipeline 231, and the filter element 241 can filter the heating network water, and the filtered heating network water flows to the storage cylinder 211 through the second replenishing water pipeline 232, which can It acts as a heat medium in the storage cylinder 211 to reduce the risk of insufficient heat medium in the energy conversion equipment.

Further, the pipeline assembly 23 also includes a first water supply switch part and a second water supply switch part (not shown in the figure), which are respectively provided in the first water supply pipeline and the second water supply pipeline. The energy conversion device also includes a liquid level monitoring element (not shown in the figure), and the liquid level monitoring element is arranged on the housing assembly 21 . That is to say, the liquid level monitoring element may be disposed in the storage cylinder 211 and/or in the electrode cylinder 212 .

The first water replenishment switch part, the second water replenishment switch part and the liquid level monitoring part are respectively connected with an external control device 30 (as shown in FIG. 1 ). The liquid level monitoring part can monitor the remaining amount of heat medium in the housing assembly 21, and feed back to the control device 30, and the control device 30 controls the conduction and connection between the first water replenishment switch part and the second water replenishment switch part based on the received heat medium remaining amount information. no.

When the liquid level monitoring part detects that the liquid level of the heat medium in the housing assembly 21 is less than or equal to the first liquid level value, the control device controls the first water supply switch part to conduct with the second water supply switch part to allow the heating network water to fill in Housing assembly 21 . When the liquid level monitoring part detects that the liquid level of the heat medium in the shell assembly is greater than or equal to the second liquid level value, the control device controls the first water replenishment switch part and the second water replenishment switch part to be turned off, and there is no need to replenish the heating network water into the shell body assembly 21. Wherein, the first liquid level value is smaller than the second liquid level value.

For example, the first liquid level value may be 1000mm, and the second liquid level value may be 1600mm, which can be adjusted according to the volume and height of the shell assembly in practical applications, and are not limited here.

In an alternative embodiment, the overflow rate of the heat medium overflowing from the exhaust valve 213 can also be pre-calculated, and the heating network water can be controlled to continuously replenish the shell assembly at the same rate, which is not limited here.

Please continue with Figure 3. In one embodiment, the water replenishment assembly 24 further includes a heating element 242 disposed between the filter element 241 and the second water replenishment pipeline 232 . The heating element 242 can heat the heating network water filtered by the filter element 241 to form heating steam, and the heating steam is passed into the storage cylinder 211 through the second replenishment pipeline 232, and condensed to form a heat medium to further purify the heating network water. When the heating network water forms heating steam, the impurities mixed in the heating network water settle at the bottom, and the heating steam diffuses upwards and enters the storage cylinder 211, which is equivalent to further filtering the heating network water.

In addition, due to the influence of the pressure change in the capacity conversion equipment, when the heating network water is directly injected into the storage cylinder 211, the pressure in the storage cylinder 211 may be too high to replenish the heating network water into the storage cylinder 211. The heating steam formed by heating the heating network water is more likely to enter the storage cylinder 211 than the heating network water.

Specifically, the heating network water can be directly replenished into the storage cylinder 211, and the storage cylinder 211 supplies heat medium to the electrode cylinder 212; The heat component 22 is returned to the electrode cylinder 212, and the specific return method is the same as that of the heat medium vapor returning to the electrode cylinder 212, which will be described in detail later.

Please continue with Figure 1 and Figure 3. In one embodiment, the energy conversion device includes a pressure monitoring element 26 , which is disposed on the shell assembly 21 and capable of monitoring the pressure inside the shell assembly 21 , and then monitors the pressure inside the energy conversion device. The pressure monitoring element 26 is connected with the control device 30 to feed back the monitored pressure to the control device 30 .

The pipeline assembly 23 includes a first heat medium pipeline 233 and a second heat medium pipeline 234 , both of which are connected to the electrode cylinder 212 and the storage cylinder 211 . The first heat medium pipeline 233 can guide the heat medium from the electrode cylinder 212 to the storage cylinder 211 , and the second heat medium pipeline 234 can flow the heat medium back from the storage cylinder 211 to the electrode cylinder 212 .

The first heat medium pipeline 233 and the second heat medium pipeline 234 are respectively provided with a first heat medium switch 2331 and a second heat medium switch 2341 . The first heat medium switch 2331 and the second heat medium switch 2341 are respectively connected to the control device 30, and the control device 30 controls whether the first heat medium switch 2331 is turned on or not to control whether the heat medium is allowed to flow from the storage cylinder 211 to the electrode cylinder 212 , and the control device 30 controls whether the second heat medium switch 2341 is turned on or not to control whether the heat medium is allowed to flow from the electrode cylinder 212 to the storage cylinder 211 .

Optionally, the first heat medium pipeline 233 can communicate with the communication pipeline 235, which means that the heat medium in the storage cylinder 211 flows through the first heat medium pipeline 233, and is pumped into the communication pipe through the first heat medium switching member 2331 235, and then flow into the electrode cylinder 212, which simplifies the pipeline structure of the energy conversion equipment.

Furthermore, the liquid level monitoring part is arranged in the electrode cylinder 212, so that when the energy conversion device is started, the control device 30 controls the first heat medium switch part 2331 to conduct, and the heat medium in the storage cylinder 211 is supplemented into the electrode cylinder 212. .

When the energy conversion device operates at a stable power, the liquid level in the shell assembly remains basically unchanged, the storage cylinder 211 does not need to replenish heat medium into the electrode cylinder 212, and the first heat medium switch 2331 is kept closed, that is, the first The heat medium pipeline is kept closed to prevent the heat medium from flowing from the storage cylinder 211 to the electrode cylinder 212 .

As mentioned above, when changing the heating capacity of the energy conversion device, it is usually to change the remaining amount of heat medium in the electrode cylinder 212 . When the heat medium flows into the electrode cylinder 212 , the heating capacity can be increased; when the heat medium flows out from the electrode cylinder 212 , the heating capacity can be reduced.

Considering that when the existing energy conversion equipment increases the heating capacity (such as heating power, etc.), the load change causes the gas inside the energy conversion equipment to fluctuate violently. The internal pressure of the energy conversion equipment rises rapidly, and when it reaches the limit pressure of the exhaust valve 213, the exhaust valve 213 opens to discharge the heat exchange steam, resulting in the loss of heat medium inside the energy conversion equipment. At this time, it is usually necessary to add a large amount of additional heat medium, which will affect the long-term stable operation of the equipment.

For this reason, in this embodiment, when the pressure monitoring component 26 detects that the pressure is greater than or equal to the first preset value, the control device 30 controls the first heating medium switching component 2331 to shut off the first heating medium pipeline 233 . When the monitored pressure is less than or equal to the second preset value, the control device 30 controls the first heat medium switching element 2331 to conduct the first heat medium pipeline 233 .

If so, the pressure of the energy conversion equipment can be maintained in a slightly positive pressure state during operation, that is, slightly higher than the standard atmospheric pressure, so that the temperature of the heat medium in the energy conversion equipment is slightly higher than the standard atmospheric pressure, for example, the temperature of water can exceed 100 ° C, and at the same time The slightly positive pressure state is beneficial to ensure the safety of energy conversion equipment.

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

For example, the first preset value and the second preset value may be gauge pressure or absolute pressure, which is not limited here. Gauge pressure refers to the amount by which the total absolute pressure exceeds the surrounding atmospheric pressure or the pressure of a certain point in a liquid above atmospheric pressure.

Taking the first preset value and the second preset value as gauge pressure as an example, the first preset value can be 45kPa (that is, the absolute pressure is 146.32545kPa), and the second preset value can be 20kPa (that is, the absolute pressure is 121.32545kPa ). The above numerical 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 to say, when replenishing the heat medium into the electrode cylinder 212, whether to supplement the heat medium can be controlled in combination with the pressure information. When the monitored pressure exceeds the safe range, the heat medium replenishment is suspended; when the pressure returns to the safe range, then Restore supplementary heat medium. If the monitored pressure is always less than or equal to the first preset value, combined with the liquid level information monitored by the liquid level monitoring part, the control device controls the first heat medium switch part 2331 to replenish the heat medium at a preset liquid level raising rate until the energy level is reached. Convert the target power of the device/target liquid level of the housing assembly.

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

Please refer to FIG. 3 and FIG. 4 in conjunction. FIG. 4 is a schematic structural diagram of the energy conversion device shown in FIG. 3 in related directions.

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

If so, the electrode cylinder 212 and the storage cylinder 211 can be arranged side by side to reduce the height of the energy conversion device and improve the compactness of the energy conversion device. Moreover, when the height of the energy conversion device is reduced, it is beneficial to enrich the application scenarios of the energy conversion device.

Further, the relative direction C of the electrode cylinder 212 and the storage cylinder 211 can be parallel to the extension direction D of the heat exchange assembly 22, and can also be perpendicular to the relative direction E of the heat exchange assembly 22, the storage cylinder 211, and the electrode cylinder 212 to further increase the energy Converting equipment compactness.

Please continue with Figure 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 cylinder 212 . The connection housing 214 is provided with a return hole 2141 . The pipeline assembly 23 includes a communication pipeline 235 connecting the electrode cylinder 212 and the return hole 2141 .

After the heat exchange steam exchanges heat with the heat network water of the heat exchange component 22, the heat medium formed by condensation due to the heat conduction to the heat network water will drop to the connection shell 214 under the action of gravity, and flow in through the return hole 2141 The communication pipeline 235, based on the principle of liquid level difference, flows back to the electrode cylinder 212 through the communication pipeline 235, and is used for subsequent heating to form heat exchange steam again, so as to realize the recycling of the heat medium.

Please continue with Figure 3. In one embodiment, the energy conversion device further includes an electrical parameter detection component 27, which is arranged on the metal part of the housing component 21, and can detect grounding resistance and/or ground voltage to determine whether the energy conversion device has Abnormal, improve the reliability of energy conversion equipment.

The electrodes 2121 are evenly distributed around the circumference of the electrode cylinder 212 , that is, the intervals between the electrodes 2121 are 120°. The three-phase electricity of the external power supply is respectively connected to the three-phase electrodes 2121, and the heat medium can be used as a load resistance.

Alternatively, please refer to FIG. 5 , which is a structural schematic diagram of an embodiment of the electrode cartridge and the electrode of the present invention. FIG. 5 exemplifies an implementation in which the number of electrodes 2121 in the electrode cylinder 212 is six, that is, three-phase and six-level. The electrodes 2121 are uniformly distributed around the circumference of the electrode cylinder 212 , that is, the electrodes 2121 are spaced apart by 60°. Among them, X1, X2, and X3 are respectively used to represent electrodes of different phases, the electrodes of the same phase are connected to the circuit of the same phase, and the electrodes of different phases are 120° to each other.
