Description

Technical Field

[0001] The utility model relates to the technical field of steam heat pumps, in particular to a high-temperature steam heat pump device. Background Art

[0002] The use of steam in the industrial field, such as petrochemical, chemical, water treatment, food, pharmaceutical, printing and dyeing industries, requires a lot of fresh steam for distillation, evaporation, concentration, drying, power transmission, etc. However, after the fresh high-temperature steam is used, some low-temperature and low-pressure steam will be generated. If these low-temperature and low-pressure steam are directly discharged, it will waste heat energy. Therefore, it is necessary to use a high-temperature steam heat pump device to reheat these low-temperature and low-pressure steam and reuse them to achieve the purpose of energy saving.

[0003] There are two types of high-temperature steam heat pump devices in the prior art:

[0004] A high-temperature steam heat pump unit disclosed in Chinese patent CN220931233U, which improves the utilization efficiency of heat energy by passing fresh steam generated by a steam generator into a steam conduit, then heating the cold water in the heating pipe through a heat-conducting baffle, and then transporting it to other processes for use;

[0005] A novel steam heat pump device for recycling waste heat steam is disclosed in Chinese patent CN217952234U. After fresh steam is fully utilized, the low-temperature and low-pressure steam generated is sent to a twin-screw steam compressor and a vapor-liquid separator for secondary heating and reuse;

[0006] However, the above two high-temperature steam heat pump devices have the following defects:

[0007] A high-temperature steam heat pump unit disclosed in Chinese patent CN220931233U has a simple structure, but using fresh steam to heat cold water may cause the remaining heat of the steam to enter other processes and fail to meet the heating demand, affecting the production of other processes; a new type of steam heat pump device for recycling waste heat steam disclosed in Chinese patent CN217952234U does not affect the production of other processes, but the low-temperature and low-pressure steam requires a twin-screw steam compressor and a vapor-liquid separator to perform secondary heating on the steam, so more equipment is needed, the structure is complex, and the cost is high. Utility Model Content

[0008] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0009] Therefore, one purpose of the utility model is to provide a high-temperature steam heat pump device, aiming to solve the problem that the high-temperature steam heat pump device in the prior art cannot have both simple structure and efficient use of steam.

[0010] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a high-temperature steam heat pump device, including a water storage barrel and a steam generator, characterized in that a drain pipe is fixedly connected to one side of the bottom of the water storage barrel, a water pump is fixedly installed at the end of the drain pipe, the output end of the water pump is fixedly connected to a water supply pipe, the end of the water supply pipe is fixedly connected to the water inlet of the steam generator, the top of the water storage barrel is fixedly connected to a conduit, the conduit passes through the interior of the water storage barrel, and a steam pipe is fixedly installed at the input end of the conduit.

[0011] Preferably, any of the above schemes is that a booster pump is fixedly installed between the conduit and the steam pipe to pressurize the steam, thereby avoiding the problem that the steam is difficult to discharge from the bottom end of the conduit.

[0012] Preferably, any of the above schemes is that the outer surface of one end of the conduit that passes through the water storage barrel is fixedly connected to a pull rod, and the bottom end of the pull rod is fixedly connected to a dispersion plate. After the steam is discharged from the bottom end of the conduit, it collides with the dispersion plate and disperses to all sides, thereby allowing the steam to fully contact the water in the water storage barrel to accelerate heat transfer.

[0013] Preferably, any of the above schemes is that a conical head is fixedly connected to the top of the dispersion plate, and the conical head is located directly below the conduit to guide and disperse the steam, thereby reducing the impact force of the steam on the dispersion plate.

[0014] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0015] 1. Low-temperature and low-pressure steam is transported into the water storage barrel through the steam pipe to the conduit, mixed with the water in the water storage barrel, and then the mixture in the water storage barrel is transported to the steam generator through a water pump for secondary heating, thereby achieving the purpose of secondary heating of low-temperature and low-pressure steam, making full use of the waste heat of low-temperature steam, thus saving a certain amount of energy, ensuring the production of high-temperature and high-pressure steam in other processes, and having the advantages of simple structure and low cost.

[0016] 2. The booster pump pressurizes the low-temperature and low-pressure steam so that the steam can push the water in the conduit downward, thereby allowing the steam to continuously enter the water storage tank, avoiding the problem of low-temperature and low-pressure steam being blocked by water, resulting in slow heat energy transfer efficiency and partial heat energy loss in the pipeline, thereby improving heat utilization.

[0017] 3. By setting a dispersion plate, the steam entering the water storage tank can be dispersed to the surroundings, thereby accelerating the heat conduction between steam and water, and quickly heating the water in the water storage tank. In addition, by setting a conical head on the dispersion plate, the force of the steam impacting the dispersion plate can be dispersed, thereby achieving the purpose of protecting the dispersion plate.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model provides a high-temperature steam heat pump device.

[0027] Embodiment 1:

[0028] like Figure 1-2 As shown, it includes a water storage barrel 1 and a steam generator 2, characterized in that a drainage pipe 11 is fixedly connected to one side of the bottom of the water storage barrel 1, a water inlet pipe 12 is fixedly connected to the top of the water storage barrel 1, and a water delivery pipe is connected to the water inlet pipe 12. When the water volume decreases, water can be added to the water storage barrel 1. A water pump 4 is fixedly installed at the end of the drainage pipe 11, and a water delivery pipe 41 is fixedly connected to the output end of the water pump 4. The end of the water delivery pipe 41 is fixedly connected to the water inlet of the steam generator 2, and the water pump 4 delivers the water in the water storage barrel 1 to the steam generator 2. The steam generator 2 heats the water to prepare high-temperature steam. A conduit 3 is fixedly connected to the top of the water storage barrel 1. The conduit 3 runs through the interior of the water storage barrel 1 and is inserted into the water in the water storage barrel 1. A steam pipe 32 is fixedly installed at the input end of the conduit 3. After the high-temperature steam is applied, the low-temperature and low-pressure steam generated is transported to the conduit 3 through the steam pipe 32, and then transported to the water storage barrel 1 through the conduit 3, so as to preliminarily heat the water in the water storage barrel 1. The steam dissipates heat and cools into water, which is mixed with the water in the water storage barrel 1.

[0029] Specifically, a safety valve 13 is fixedly installed on the top of the water storage barrel 1. When the air pressure in the water storage barrel 1 is too high, the safety valve 13 can discharge a portion of the gas to avoid the problem of excessive pressure in the water storage barrel 1.

[0030] Embodiment 2:

[0031] Since the conduit 3 is inserted into the water, it is difficult for the low-temperature and low-pressure steam to enter the water storage barrel 1 from the conduit 3, which slows down the efficiency of heat transfer. Figure 1 As shown, on the basis of the first embodiment, a booster pump 31 is fixedly installed between the conduit 3 and the steam pipe 32. The booster pump 31 pressurizes the low-temperature and low-pressure steam so that the steam can push the water in the conduit 3 downward, thereby allowing the steam to continuously enter the water storage barrel 1.

[0032] Embodiment three:

[0033] like Figure 3 As shown, on the basis of the second embodiment, a pull rod 5 is fixedly connected to the outer surface of one end of the conduit 3 that passes through the water storage barrel 1, and a dispersion plate 51 is fixedly connected to the bottom end of the pull rod 5. After the low-temperature and low-pressure steam is quickly discharged from the bottom end of the conduit 3, it collides with the dispersion plate 51 and can be dispersed around along the dispersion plate 51, thereby increasing the contact area between the steam and the water in the water storage barrel 1, thereby accelerating the heat conduction between the steam and the water, and can quickly heat up the water in the water storage barrel 1.

[0034] Further preferably, a conical head 52 is fixedly connected to the top of the dispersion plate 51, and the conical head 52 is located directly below the conduit 3. After the steam is discharged from the conduit 3, when it passes through the conical head 52, the inclined outer surface of the conical head 52 can disperse the steam, causing the steam to move obliquely toward the dispersion plate 51, and then dispersed through the dispersion plate 51, thereby dispersing the force of the steam impacting the dispersion plate 51, thereby achieving the purpose of protecting the dispersion plate 51.

[0035] The working principle of the utility model is as follows: when in use, the water inlet pipe 12 of the water storage barrel 1 is connected to the water outlet of the solar water heater, and the water inlet of the solar water heater is connected to a water pipe for conveying water to the solar water heater. After the solar water heater heats the water to a certain temperature, low-temperature and low-pressure water vapor is generated, and then the low-temperature water and the low-temperature and low-pressure water vapor are conveyed to the water storage barrel 1, and then the low-temperature and low-pressure steam generated after the high-temperature steam is applied is conveyed to the conduit 3 through the steam pipe 32. On the way, the booster pump 31 pressurizes the low-temperature and low-pressure steam so that it can smoothly pass through the conduit 3 into the low-temperature water and low-temperature and low-pressure water vapor in the water storage barrel 1, and preliminarily heats the low-temperature water and low-pressure water vapor in the water storage barrel 1. The heated water is conveyed to the steam generator 2 through the water pump 4 for secondary heating. Since the low-temperature water is heated again after mixing with the low-temperature and low-pressure water vapor, a certain amount of energy can be saved when it is conveyed to the steam generator 2 for secondary heating.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. Low-temperature and low-pressure steam is transported into the water storage barrel 1 through the steam pipe 32 to the conduit 3, so that the water in the water storage barrel 1 is heated, and the steam is cooled into water after heat dissipation, and mixed with the water in the water storage barrel 1, and then the mixture in the water storage barrel 1 is transported to the steam generator 2 through the water pump 4 for secondary heating, thereby achieving the purpose of secondary heating of the low-temperature and low-pressure steam, making full use of the waste heat of the low-temperature steam, thereby saving a certain amount of energy, ensuring the production of high-temperature and high-pressure steam in other processes, and having the advantages of simple structure and low cost.

[0038] 2. By arranging a booster pump 31 between the conduit 3 and the steam pipe 32, the booster pump 31 pressurizes the low-temperature and low-pressure steam, so that the steam can push the water in the conduit 3 downward, thereby allowing the steam to continuously enter the water storage tank 1, thereby avoiding the problem that the low-temperature and low-pressure steam is blocked by water, resulting in slow heat energy transfer efficiency and partial heat energy loss in the pipeline, thereby improving heat utilization.

[0039] 3. By providing a dispersion plate 51, the steam entering the water storage barrel 1 can be dispersed to the surroundings, thereby increasing the contact area between the steam and the water in the water storage barrel 1, thereby accelerating the heat conduction between the steam and the water, and quickly heating the water in the water storage barrel 1. In addition, by providing a conical head 52 on the dispersion plate 51, the force of the steam impacting the dispersion plate 51 can be dispersed, thereby achieving the purpose of protecting the dispersion plate 51.
