Description

Technical Field

[0001] The invention relates to the field of hot water storage tanks, and in particular to a self-cleaning high-temperature steam heating water tank and a use method thereof. Background Art

[0002] A hot water storage tank is a device that uses water as a medium to store heat. Existing hot water storage tanks generally store heat energy by directly injecting hot water. However, they are subject to great limitations during use. Moreover, in actual applications, they can only store heat energy but not water, and have a small scope of application.

[0003] A stepless stratified hot water storage tank with a publication number of CNB, a stepless stratified hot water storage tank, comprising a water tank, a heat exchange tube arranged at the bottom of the water tank, an isolation cover with a gap between the heat exchange tube and the bottom of the water tank, the top of the isolation cover is connected to a drainage element combination tube extending vertically upward, the outer wall of the drainage element combination tube is fin-shaped, and the tube wall between each layer of fins is connected to the water tank. The drainage element combination tube is composed of drainage elements, the drainage element is a frustum-shaped tube body, and a circle of fixed guide eaves extends outward from the end with a larger opening of the frustum-shaped tube body, and the fixed guide eaves are provided with fixed screw holes, and multiple drainage elements are overlapped in sequence and connected and fixed by fixed studs at the fixed screw holes to form a drainage element combination tube.

[0004] The above technical solution realizes the synchronous storage of cold water and hot water by setting an isolation cover in the water tank. However, the heat exchange effect between cold water and hot water is single, and the storage and utilization efficiency of thermal energy is low.

[0005] At the same time, when the heat storage box is performing water storage operation, impurities in the water are precipitated during the heat exchange of cold water in the heat pipe, thereby generating scale on the inner wall of the heat pipe, which in turn causes the heat pipe to be blocked, causing the flow rate discharged from the pipe to change. At the same time, the scale in the heat pipe affects the heat exchange between cold water and steam, so that after the water flows through the pipe to the heat storage box, the temperature and air pressure in the heat storage box change, which may cause safety accidents in serious cases. The prior art lacks a technical solution for judging whether scaling occurs and cleaning it by changing the flow rate when the heat storage box is performing water storage operation. Summary of the invention

[0006] The object of the present invention is to provide a self-cleaning high-temperature steam heating water tank and a method of using the same to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a self-cleaning high-temperature steam heating water tank, comprising a water storage tank, a steam injection assembly is provided on the top of the water storage tank, a heat storage tank is provided inside the water storage tank, a condensation assembly is provided on the top of the heat storage tank, and a bearing assembly is provided on the surrounding side of the heat storage tank.

The condensed water in the heat exchange tube 12 can exchange heat with the water in the hot water tank again to achieve the recovery of the waste heat of the steam.

[0056] Embodiment 2

[0057] Although the above embodiment can recycle steam, when the heat storage tank 3 is performing water storage operation, impurities in the water are precipitated during the heat exchange of cold water in the heat pipe 407, thereby generating scale on the inner wall of the heat pipe 407, thereby blocking the heat pipe 407, causing the flow rate discharged from the conduit 401 to change. At the same time, the scale in the heat pipe 407 affects the heat exchange between cold water and steam, so that after the water flows into the heat storage tank 3 through the conduit 401, the temperature and air pressure in the heat storage tank 3 change, and safety accidents may occur in serious cases. The prior art lacks a technical solution for judging whether scaling occurs and cleaning it by changing the flow rate when the heat storage tank 3 is performing water storage operation. In view of this, technical improvements are made on the basis of the first embodiment, and the specific solution is as follows:

[0058] Reference Figures 1 to 13 A self-cleaning high-temperature steam heating water tank comprises a water storage tank 1, a steam injection assembly 2 is provided on the top of the water storage tank 1, a heat storage tank 3 is provided inside the water storage tank 1, a condensation assembly 4 is provided on the top of the heat storage tank 3, and a bearing assembly 5 is provided on the surrounding side of the heat storage tank 3.

[0059] The bearing assembly 5 includes a guide plate 501 arranged on the outer wall of the heat storage tank 3, the inner circle of the guide plate 501 is sealingly and slidably connected to the outer wall of the heat storage tank 3, the top of the guide plate 501 is provided with an array-distributed expansion assembly 6, the top of the expansion assembly 6 is provided with a filter screen 502 with an annular structure, the inner circle of the filter screen 502 is fixedly connected to the outer wall of the heat storage tank 3, and the outer circle of the filter screen 502 is fixedly connected to the inner wall of the water storage tank 1.

[0060] The expansion assembly 6 includes an elastic airbag 601 fixedly connected to the guide plate 501, the top of the elastic airbag 601 is connected to the filter 502, the top of the elastic airbag 601 is provided with an air outlet valve 602, the outer side wall of the elastic airbag 601 is provided with an air inlet pipe 603, and the air inlet pipe 603 is connected to the inside of the heat storage box 3.

[0061] The condensing assembly 4 includes a conduit 401 , the water outlet of which is located inside the heat storage tank 3 , a floating assembly 7 is provided inside the conduit 401 , a connecting pipe 8 is provided outside the conduit 401 , a one-way valve is provided inside the connecting pipe 8 , and the connecting pipe 8 is located above the floating assembly 7 .

[0062] Specifically, the floating assembly 7 includes a bracket fixedly connected to the inside of the catheter 401, an expansion member 701 is provided below the bracket, a delivery pipe 702 is provided on the outer wall of the expansion member 701, the other end of the delivery pipe 702 passes through the catheter 401 and is connected to the inside of the elastic airbag 601, a stop valve is provided inside the delivery pipe 702, and the connecting pipe 8 is located above the bracket away from one end of the expansion ball.

[0063] In the initial state, the elastic airbag 601 is in a contracted state, the expansion ball is in a contracted state, the stop valve in the delivery pipe 702 is in a closed state, the water inlet end of the connecting pipe 11 is located above the guide plate 501, and the water inlet end of the connecting pipe 11 is provided with a stop valve. In the initial state, the stop valve in the connecting pipe 11 is in a closed state, that is, the space above the guide plate 501 cannot be connected to the heat exchange tube 12 through the connecting pipe 11; the air outlet valve 602 is in a closed state, that is, the gas inside the elastic airbag 601 cannot be discharged through the air outlet valve 602.

[0064] During normal use, cold water is injected into the water tank 1 through the water supply pipe 15, and the water tank 1 stores the cold water. When the liquid level in the water tank 1 reaches the set value, the water supply pipe 15 is controlled to stop further injecting water into the water tank 1, and the liquid level of the water tank 1 is located at the bottom of the heat storage tank 3.

[0065] The water pump 413 and the external steam generator are controlled to start, the water pump 413 pumps out the cold water in the water tank 1, and discharges the cold water to the liquid inlet pipe 409 through the water pumping pipe 412, and the cold water entering the liquid inlet pipe 409 enters the guide pipe 406 through the first installation pipe 411; the external steam generator transmits steam into the extension cover 202 through the steam injection pipe 201, and the steam entering the extension cover 202 is ejected from the nozzle 203, and the steam ejected from the nozzle 203 is connected with the heat-conducting fins 408 on the guide pipe 406. The steam heats the cold water in the guide pipe 406, so that the cold water in the guide pipe 406 becomes hot water, and the cold water in the guide pipe 406 cools down and condenses the steam, so that the steam forms condensed water.

[0066] The condensed water formed by the steam gathers at the top of the collecting cover 402. After a certain amount of condensed water accumulates in the collecting cover 402, it flows outward through the overflow groove 405 and finally flows to the top of the guide plate 501. Although part of the steam will also be discharged to the outside through the overflow groove 405, since the liquid inlet pipe 409 and the liquid discharge pipe 410 are both located on the outside of the fixed cover 403, the cold water in the liquid inlet pipe 409 will also cool down and condense the steam, and finally the condensed water will fall on the top of the guide plate 501. Since the inner ring of the guide plate 501 is sealed and slidably connected to the heat storage tank 3, and the on-off valve inside the connecting pipe 11 is in a closed state, the condensed water can continue to remain above the guide plate 501.

[0067] The hot water in the guide pipe 406 enters the drain pipe 410 through the second installation pipe 414, and the drain pipe 410 discharges the hot water into the heat storage tank 3 through the conduit 401. The heat storage tank 3 keeps the discharged hot water warm. When it is needed, just open the drain pipe 10 for use.

[0068] At the same time, as more and more hot water flows into the heat storage tank 3, the hot water squeezes the gas in the heat storage tank 3, so that the gas is discharged into the elastic airbag 601 through the air inlet pipe 603, causing the elastic airbag 601 to expand. Since the two ends of the elastic airbag 601 are fixedly connected to the filter 502 and the guide plate 501 respectively, and the inner ring of the guide plate 501 is sealed and slidably connected to the outer wall of the heat storage tank 3, the elastic airbag 601 synchronously drives the guide plate 501 to move downward during the expansion process, and the guide plate 501 can still receive condensed water during the downward movement. When the elastic airbag 601 expands to the maximum value, the water pump 413 and the steam generator are controlled to stop working, and the hot water flowing into the heat storage tank 3 is kept warm by the heat storage tank 3.

[0069] It should be noted that the expansion direction of the elastic airbag 601 inside the device is axial expansion. The expansion of the elastic airbag 601 is driven by the gas discharged into the elastic airbag 601 by the heat storage tank 3. The condensed water falling on the guide plate 501 cannot generate enough gravity to stretch the elastic airbag 601.

[0070] Since a flow sensor is provided inside the conduit 401, the capacity of hot water in the heat storage tank 3 per unit time can be obtained by detecting the value of the flow sensor and the working time of the flow sensor; and whether the temperature in the heat storage tank 3 exceeds the set value can be obtained by detecting the expansion amount of the elastic airbag 601 per unit time.

[0071] It should be noted that the guide plate 501 in this embodiment has a funnel-shaped cross section, and the inner ring of the guide plate 501 is sealingly and slidably connected to the outer wall of the heat storage tank 3, and the outer ring of the guide plate 501 does not contact the inner wall of the water storage tank 1, so that after the space between the guide plate 501 and the heat storage tank 3 is filled with condensed water, the excess condensed water will directly flow into the water storage tank 1 over the guide plate 501.

[0072] When the control system detects that the induction value of the flow sensor decreases, and the expansion amount of the elastic airbag 601 is greater than the set value, it indicates that the liquid inlet pipe 409 is blocked, so that the amount of cold water flowing into the guide pipe 406 is reduced. When the cold water and steam perform heat exchange, the temperature of the heated cold water is increased. Therefore, after the heated cold water flows into the heat storage tank 3, the water temperature in the heat storage tank 3 increases, the air pressure increases, and finally the expansion amount of the elastic airbag 601 increases.

[0073] At this time, the control system controls the on-off valve in the delivery pipe 702 to open, so that part of the gas in the elastic airbag 601 enters the delivery pipe 702, and the gas in the delivery pipe 702 is delivered to the expansion member 701, so that the expansion member 701 expands and blocks the water outlet of the conduit 401. Since the flow guide pipe 406, the heat conduction pipe 407, the liquid inlet pipe 409, the liquid discharge pipe 410, the first installation pipe 411 and the second installation pipe 414 in the device are all flexible pipes, the expansion member 701 blocks the water outlet of the conduit 401. Afterwards, as the water pumping pipe 412 continuously injects water into the guide pipe 406, the liquid inlet pipe 409 and the like will expand and deform to varying degrees, that is, the internal pressure will increase. When the pressure exceeds the set value, the water pressure will open the one-way valve in the connecting pipe 8, and the connecting pipe 8 will relieve the pressure on the water flow in the liquid inlet pipe 409. During the pressure relief process, the liquid inlet pipe 409 and the like will shrink. During the expansion and contraction process, the stress structure of the scaling in the liquid inlet pipe 409 will be destroyed, thereby achieving a clearing effect. The destroyed scaling materials will be discharged along the connecting pipe 8 to the upper surface of the filter screen 502.

[0074] At the same time, during the process of water flow pressure relief, the air outlet valve 602 on the elastic airbag 601 is controlled to open, so that the gas in the elastic airbag 601 and the gas in the expansion ball are discharged. After the gas in the expansion ball is discharged, the water flow entering from the conduit 401 can continue to flow into the heat storage tank 3, and the gas in the elastic airbag 601 is discharged. Due to the elastic restoring force of the elastic airbag 601, the elastic airbag 601 drives the guide plate 501 to move upward. During the upward movement of the guide plate 501, the stop valve in the connecting pipe 11 is opened, so that the condensed water carried by the guide plate 501 can flow along the connecting pipe 11 to the heat exchange pipe 12, and finally discharged from the drain port 13 to the inside of the water storage tank 1. When the condensed water flows in the heat exchange pipe 12, it exchanges heat with the hot water in the heat storage tank 3, so that the temperature of the hot water in the heat storage tank 3 is reduced, and the temperature in the heat storage tank 3 is prevented from being too high, which causes the internal pressure of the heat storage tank 3 to be too high.

[0075] As the elastic airbag 601 drives the guide plate 501 upward, as the condensed water on the guide plate 501 becomes less and less, the top of the guide plate 501 eventually collides with the bottom of the filter 502, causing the scale above the filter 502 to vibrate and break away from the mesh of the filter 502, thereby preventing the scale from clogging the filter 502.
