Technical Field

[0001] The present invention relates to the technical field of steam generation, in particular to a novel steam generator for generating highly saturated steam. Background Art

[0002] A steam generator is a thermal energy conversion device that converts heated water into steam. It is widely used in industries such as industry, energy, healthcare, and food processing. It evaporates water to produce high-temperature, high-pressure, or low-pressure steam to meet the needs of different scenarios.

[0003] For example, the invention with authorization publication number CN101268307B provides a steam generator, in which a water supply port is provided at the lower side of a container formed into a hollow shape, and on the other hand, a discharge port for discharging a gas-liquid two-phase flow is provided at the upper end portion. Several heaters are also provided in the container as heating mechanisms for heating water to generate a gas-liquid two-phase flow.

[0004] Taking the above-mentioned steam generator as an example, several heaters are set up to ensure the speed of water generating steam.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Figures 1-12As shown, the present invention provides a technical solution for a new type of steam generator for generating highly saturated steam, comprising a generator housing 1 and a support base 6, an exhaust pipe 5 is fixedly inserted at the top of the generator housing 1, and a heating structure 7 is connected to the bottom of the exhaust pipe 5. The heating structure 7 includes a plurality of electric heaters 72, a heat conducting plate 1 73, a heat conducting plate 2 75 and a centrifugal gas-liquid separator 76 arranged in sequence from bottom to top, a water supply structure 2 is provided between the heating structure 7 and the generator housing 1, and the water supply structure 2 includes a fixed portion on the generator housing 1. A fixedly inserted guide pipe 25, several flow control components installed inside the guide pipe 25, a guide box 210 set at the bottom of the heat conduction plate 73, several injection components fixedly installed inside the guide box 210, a sealed tube 223 fixedly installed inside the guide box 210 and a liquid supply component set between the several injection components, a sealed tube 222 fixedly connected to the inside of the guide box 210, a drive structure 4 is passed through the inside of the sealed tube 223, and several electric heaters 72 all pass through the guide box 210.

[0022] Specifically, such as Figure 1 As shown, the support base 6 is fixedly installed at the bottom of the generator housing 1, and the support base 6 supports the generator housing 1. A drain valve 3 is fixedly embedded on the top of the support base 6, and the drain valve 3 is fixedly installed at the bottom outside the generator housing 1. The drain valve 3 is controlled to open to discharge the water inside the generator housing 1, which is convenient for discharging the sewage generated during the cleaning process inside the generator housing 1.

[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, one end of the diversion pipe 25 extends to the outside of the generator housing 1 and is fixedly connected to a three-way valve 23. The water inlet end of the one-way valve 22 fixedly connected to one end of the three-way valve 23 is fixedly connected to a connecting pipe 21. The connecting pipe 21 is connected to the water supply system. Under the one-way conduction characteristic of the one-way valve 22, the high-temperature water inside the generator housing 1 cannot flow back to the water supply system, thereby ensuring the safety of the water supply system. A drain pipe 24 is fixedly connected between the normally closed end of the three-way valve 23 and the generator housing 1. When the three-way valve 23 is in the normally open state, water is supplied to the inside of the generator housing 1 through the diversion pipe 25. The normally closed end of the three-way valve 23 is controlled to open, and water can be supplied to the inside of the generator housing 1 through the drain pipe 24.

[0024] When water is supplied to the interior of the generator housing 1 through the guide pipe 25, since a number of flow control components are provided inside the guide pipe 25, each flow control component includes a blocking plate 26 that is slidably inserted on the guide pipe 25, and a hydraulic cylinder 28 and a telescopic rod 29 are provided inside the telescopic tube 27 that is fixedly connected between one side of the blocking plate 26 and the inner wall of the generator housing 1. The hydraulic cylinder 28 and the telescopic rod 29 are located inside the sealed space separated from the water formed by the blocking plate 26 and the telescopic tube 27. The housings of the hydraulic cylinder 28 and the telescopic rod 29 are fixedly connected to the inner wall of the guide pipe 25. The hydraulic cylinder 28 and the telescopic rod 29 are fixedly connected to the inner wall of the guide pipe 25. 8 and the piston ends of the telescopic rod 29 are fixedly connected to the blocking plate 26. Under the action of the hydraulic cylinder 28 and the telescopic rod 29, the blocking plate 26 moves according to the preset trajectory. The top of the diversion pipe 25 passes through the diversion box 210. One of the blocking plates 26 is arranged inside the diversion box 210. One of the flow control components is arranged inside the diversion box 210. The hydraulic cylinder 28 in the flow control component is controlled to contract so that the blocking plate 26 moves completely into the diversion pipe 25. The interior of the diversion pipe 25 is connected to the interior of the diversion box 210, so that water can be supplied to the interior of the diversion box 210.

[0025] Specifically, such as Figure 4 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the vertical circular tube 211 in each spray assembly is fixedly installed inside the guide box 210, and a number of atomizing nozzles 214 are fixedly connected to the inside of the vertical circular tube 211. A number of electric heaters 72 pass through the guide box 210. The vertical circular tube 211 corresponds to the electric heater 72 one by one and is sleeved on the outside of the electric heater 72. When the atomizing nozzle 214 is not spraying water, the part of the electric heater 72 passing through the inside of the vertical circular tube 211 will not be affected by the water inside the guide box 210. A guide groove 213 is provided at the top of the vertical circular tube 211, and a number of atomizing nozzles 214 are connected to the inside of the guide groove 213. A number of guide grooves 212 are provided on the outside of the vertical circular tube 211. The guide groove 213 is connected to the inside of the guide box 210 through a number of guide grooves 212, and the atomizing nozzles 214 are connected to the inside of the guide box 210.

[0026] The guide box 215 fixedly connected to the bottom end of the vertical circular tube 211 is fixedly embedded in the bottom of the guide box 1 210. The inner diameter of the hydraulic expansion member 216 fixedly connected inside the guide box 215 is slightly smaller than the inner diameter of the vertical circular tube 211, so that the water inside the vertical circular tube 211 can fall into the inside of the generator housing 1.

[0027] The water pump 221 in the liquid supply component is fixedly installed inside the guide box 1 210, the water inlet end of the water pump 221 is fixedly connected to the sealing pipe 1 222, and the water outlet end of the water pump 221 is fixedly connected to the guide pipe 3 219, one end of which is fixedly connected to the guide box 3 218. The guide box 3 218 is fixedly installed on the outside of the sealing pipe 1 222 and the relative position between the guide box 1 210 remains unchanged. The guide box 3 218 and each guide box 2 215 are fixedly connected to the guide pipe 2 217. Under the action of the guide box 3 218 and several guide pipes 2 217, the guide box 3 218 and the guide pipes 2 The water pump 221 can supply water to the interior of several diversion boxes 215. During the process of supplying water to the interior of several diversion boxes 215 through the liquid supply component, the hydraulic sensor 220 fixedly connected to one side of the diversion pipe 3 219 detects the internal hydraulic pressure of the diversion pipe 3 219. When the internal hydraulic pressure of the diversion pipe 3 219 reaches a preset value, the solenoid valve 225 fixedly connected to the water inlet end of the water pump 221 is controlled to close, so that the internal hydraulic pressure of the diversion pipe 3 219, the diversion box 3 218, the diversion box 2 215 and the hydraulic expansion member 216 remains stable.

[0028] Specifically, such as Figure 2 、 Figure 4 and Figure 6 As shown, the forward and reverse motors 42 in the driving structure 4 are arranged on the outside of the generator housing 1, and two fixed vertical plates 41 are fixedly connected between the outer wall of the forward and reverse motor 42 and the generator housing 1, so that the forward and reverse motors 42 can work stably. A transmission seat 45 is installed on the outside of the screw rod 44 fixedly connected to the output end of the forward and reverse motor 42 through a nut pair. The transmission seat 45 is fixedly connected to the sealing tube 223, and the bottom end of the screw rod 44 is rotatably connected to the support base 6 to be able to rotate stably. When the screw rod 44 rotates, the screw rod 44 drives the transmission seat 45, the sealing tube 223 and the guide box 1 210 fixedly connected to the sealing tube 223 to move up and down. A brake 43 is provided on the outside of the screw rod 44, and the brake 43 is fixedly connected between the two fixed vertical plates 41. After the forward and reverse motor 42 completes its work, the brake 43 is controlled to work, so that the screw rod 44 can be braked and limited.

[0029] Reserved grooves 224 are provided at the top and bottom of the guide box 1 210 , and the sealing tube 223 is arranged between the two reserved grooves 224 . The screw rod 44 passes through the two reserved grooves 224 , and the screw rod 44 will not destroy the sealing inside the guide box 1 210 .

[0030] Specifically, such as Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, a mounting base 71 is fixedly connected between the electric heater 72 and the supporting base 6. The mounting base 71 supports and mounts the electric heater 72 to ensure the sealing of the wire connection of the electric heater 72 and the safety of the use of the mounting base 71. The heat conducting plate 1 73 is fixedly mounted on the bottom outer side of the centrifugal gas-liquid separator 76 and is fixedly connected to the generator housing 1. The centrifugal gas-liquid separator 76 and the heat conducting plate 1 73 cooperate with each other to form a partition frame with good sealing performance inside the generator housing 1. Several small holes 74 are opened on the outside of the heat conducting plate 1 73. The tops of several electric heaters 72 all pass through the heat conducting plate 1 73. The heat conducting plate 2 75 is fixedly mounted on the tops of several electric heaters 72. The heat conducting plate 2 75 is heated by the several electric heaters 72 to maintain a high temperature state.

[0031] The centrifugal gas-liquid separator 76 is fixedly installed at the bottom end of the exhaust pipe 5. Several air guide pipes 77 are fixedly installed on the outside of the centrifugal gas-liquid separator 76. One end of the inclined air guide pipe 77 is set on the top of the second heat conducting plate 75. The air guide pipe 77 introduces steam into the centrifugal gas-liquid separator 76. The steam enters the centrifugal gas-liquid separator 76 along the tangential direction of the high-speed rotating impeller inside the centrifugal gas-liquid separator 76. The high-speed rotation of the steam generates centrifugal force. Under the action of the centrifugal force, the liquid in the steam is thrown out and contacts the inner wall of the centrifugal gas-liquid separator 76 and is discharged into the centrifugal gas-liquid separator 76. The inner wall of the separator 76 guides the downward flow, and a one-way valve 2 78 is fixedly installed at the bottom of the centrifugal gas-liquid separator 76. The bottom end of the one-way valve 2 78 is arranged inside the sealing tube 1 222. The water separated from the inside of the centrifugal gas-liquid separator 76 flows out along the inner wall of the centrifugal gas-liquid separator 76 and the one-way valve 2 78 and falls into the inside of the generator housing 1, and the air guide pipe 77 is arranged on the upper end of the outer side of the centrifugal gas-liquid separator 76. The liquid generated inside the centrifugal gas-liquid separator 76 cannot flow out through the air guide pipe 77, so as to avoid water accumulation on the top of the heat conduction plate 1 73 to increase the water content of the steam.

[0032] In this application, the generator housing 1, support base 6, exhaust pipe 5, heating structure 7, water supply structure 2 and drive structure 4 constitute a steam generator. Connecting the steam generator to a human-computer interaction device to control its automated operation is an existing technology and will not be described in detail here.

[0033] The working principle of the steam generator is as follows: The water supply system connected to the connecting pipe 21 is controlled to supply water to the connecting pipe 21, and the normally closed end of the three-way valve 23 is controlled to open. Under the action of the three-way valve 23 and the drain pipe 24, water enters the inside of the generator housing 1. When the water level inside the generator housing 1 reaches a preset value, the three-way valve 23 is controlled to stop working. At this time, the guide box 210 is located above the water surface. Then, several electric heaters 72 in the heating structure 7 are controlled to work to heat the water inside the generator housing 1. As the working time of the electric heater 72 increases, the water is heated into steam to perform steam generation.

[0034] After the electric heater 72 has been working for a period of time, the water supply system is controlled to work again to supply water to the three-way valve 23, and the water enters the diversion pipe 25 fixedly connected to the normally open end of the three-way valve 23. At this time, the hydraulic cylinder 28 in the flow control component inside the diversion box 210 is controlled to work and contract, and the blocking plate 26 on one side of the hydraulic cylinder 28 completely enters the diversion pipe 25. The water inside the diversion pipe 25 enters the diversion box 210, and enters the diversion groove 2 213 through the diversion box 210. The atomizing nozzle 214 is connected to the water source. As the water supply time increases, the water pressure inside the diversion box 210 increases to reach the threshold of the atomizing nozzle 214. The atomizing nozzle 214 atomizes the water and sprays it out. The vertical circular tube 211 corresponds one to one with the several electric heaters 72 that pass through the diversion box 210. There are several atomizing nozzles fixedly installed inside the vertical circular tube 211. 214 surrounds the outside of the electric heater 72, and the water mist sprayed by the atomizing nozzle 214 moves directly to the outside of the electric heater 72; after a period of time, the water supply system supplies water to the inside of the guide box 210 at a preset flow rate and water pressure, so that several atomizing nozzles 214 atomize the water supplied to the inside of the generator housing 1 and then spray it to the outside of the electric heater 72. Through the cooperation of the guide box 210, several vertical circular tubes 211 and several atomizing nozzles 214, a small amount of water is continuously supplied to the inside of the generator housing 1 to balance the internal pressure of the generator housing 1. The high-temperature electric heater 72 heats most of the water mist into steam, and a small amount of water is heated and falls into the inside of the generator housing 1 to continue heating. The scale is concentrated on the outside of the electric heater 72 to reduce the scale coverage area inside the steam generator, while accelerating the speed at which the supplemented water is processed into steam to ensure sufficient steam supply.

[0035] The centrifugal gas-liquid separator 76 and the heat conducting plate 1 73 cooperate to form a partition frame with good sealing performance inside the generator housing 1. The steam generated by the water heated at the bottom of the partition frame moves upward through a number of small holes 74 opened on the outside of the heat conducting plate 1 73. Since the heat conducting plate 1 73 is arranged on the top of the guide box 1 210 and has a slightly lower contact temperature with the water newly added to the generator housing 1, the heat conducting plate 1 73 plays a role in the preliminary dehydration of the steam. After the steam collides with the high-temperature heat conducting plate 2 75 under the guidance of the small holes 74, the air flow and liquid in the steam are separated by the collision. Separation, a small amount of liquid is heated into steam by the high-temperature heat conducting plate 2 75, and the steam is heated by the high-temperature heat conducting plate 2 75 to ensure the temperature. During the steam dehydration process, the steam temperature can be guaranteed and a small amount of water in the steam can be evaporated to ensure that the water is quickly utilized and reduce the generation of "thousand-boiled water". Finally, the steam enters the centrifugal gas-liquid separator 76 for dehydration again, and then the highly saturated steam is discharged through the exhaust pipe 5.

[0036] In addition, when the steam generator has been used for a period of time and the scale on the outside of the electric heater 72 for heating water needs to be treated during maintenance, the drain valve 3 is controlled to open to empty the interior of the generator housing 1, and the hydraulic cylinder 28 in the flow control component at the bottom of the outside of the diversion pipe 25 is controlled to work and retract, and the blocking plate 26 connected to the hydraulic cylinder 28 completely enters the inside of the diversion pipe 25 to empty the inside of the blocking plate 26. After a period of time, the hydraulic cylinder 28 is controlled to work and push the blocking plate 26 to reset, and the drain valve 3 is controlled to work and close, and the hydraulic cylinder 28 in the flow control component located inside the diversion box 210 is controlled to work and retract. At this time, the diversion pipe 25 is connected to the inside of the diversion box 210.

[0037] Subsequently, the water supply system is controlled to supply a solution with a certain concentration of descaling agent into the diversion pipe 1 25. After the solution enters the diversion box 1 210, the solenoid valve 225 is controlled to open, and the water pump 221 is controlled to extract the solution inside the diversion box 1 210. Under the action of the liquid supply component, several hydraulic expansion pieces 216 fixedly connected inside the diversion box 215 are filled with water. As the working time of the water pump 221 increases, the hydraulic expansion piece 216 expands. After expansion, the hydraulic expansion piece 216 is tightly attached to the outside of the electric heater 72. The hydraulic sensor 220 monitors the internal hydraulic pressure of the diversion pipe 3 219. When the internal hydraulic pressure of the hydraulic sensor 220 reaches a preset value, the solenoid valve 225 is controlled to stop working and close. The water pump 221 is controlled to stop working, and the interior of the diversion pipe 25 is no longer connected to the interior of the diversion box 210. At this time, under the action of the diversion box 215 and the hydraulic expansion member 216, the part of the electric heater 72 located inside the vertical circular tube 211 is sealed and stored, and as the hydraulic pressure inside the diversion box 210 increases, several atomizing nozzles 214 spray the solution to the outside of the electric heater 72. After a period of time, the supply of solution to the interior of the diversion pipe 25 is stopped, and the hydraulic cylinder 28 in the liquid supply assembly inside the diversion box 210 is controlled to work to drive the blocking plate 26 to reset. The solution is immersed in the outside of the part of the electric heater 72 located inside the vertical circular tube 211, and the solution softens the scale on the outside of the electric heater 72.

[0038] After a period of time, the solenoid valve 225 is controlled to open for a short period of time, so that the pressure inside the hydraulic expansion member 216 is slightly relieved, and the hydraulic expansion member 216 still remains in close contact with the electric heater 72, and the interior of the vertical circular tube 211 maintains a certain degree of sealing, and the solution will not leak from the interior of the vertical circular tube 211. The forward and reverse motor 42 is controlled to work forward to drive the screw rod 44 to rotate clockwise, and the screw rod 44 drives the guide box 1 210 to move downward through the transmission seat 45 and the sealing tube 223. The top of the electric heater 72 passes through the guide box 1 210 and the outer wall of the electric heater 72 is in close contact with the guide box 1 210. During the downward movement of the guide box 1 210, the electric heater 72 is pressed against the guide box 1 The outside of the electric heater 72 is cleaned, and the hydraulic expansion member 216 can be deformed to meet the need of moving the guide box 210 downward. The solution stored in the vertical circular tube 211 will not leak in large quantities. The guide box 210 moves down a certain distance to clean the part of the electric heater 72 soaked in the solution. After the guide box 210 moves to the outside of the next flow control component, the forward and reverse motors 42 are controlled to stop working, the water pump 221 is controlled to work, and the solenoid valve 225 is controlled to open. The water pump 221 supplies liquid to the inside of the hydraulic expansion member 216 through the liquid supply component, so that the hydraulic pressure of the hydraulic expansion member 216 is restored, and the cleaning work of the outside of the electric heater 72 is completed once.

[0039] After the outer side of the electric heater 72 is cleaned for 3 to 4 times, the solenoid valve 225 is controlled to be open for a period of time. Since the hydraulic pressure required for the elastic expansion of the hydraulic expansion member 216 is much higher than the hydraulic pressure of the atomized liquid of the atomizing nozzle 214, the hydraulic expansion member 216 contracts, and the solution inside the hydraulic expansion member 216 returns to the inside of the guide box 210. After the hydraulic expansion member 216 contracts, the scale and solution inside the vertical circular tube 211 are discharged, and then the hydraulic cylinder 28 in the flow control component inside the guide box 210 is controlled to work and contract, and the solution is supplied to the inside of the guide box 210 through the guide pipe 25, and the liquid supply component is controlled to work to several guides. The hydraulic expansion member 216 fixedly connected inside the box 215 is filled with water, causing several hydraulic expansion members 216 to expand. When the hydraulic pressure detected by the hydraulic sensor 220 reaches a preset value, the water pump 221 and the solenoid valve 225 stop working. After the hydraulic pressure inside the guide box 1 210 is reached, several atomizing nozzles 214 spray a certain amount of solution into the vertical circular tube 211 sealed by the hydraulic expansion member 216. After that, the hydraulic cylinder 28 in the flow control component is controlled to work and extend, and the guide pipe 1 25 and the guide box 1 210 are sealed, and the stage cleaning work on the outside of the electric heater 72 can be carried out again to ensure that the solution has a softening effect on the scale on the outside of the electric heater 72.

[0040] When the outside of the electric heater 72 is cleaned, the drain valve 3 is controlled to open to discharge the solution and scale, and the forward and reverse motor 42 is controlled to reverse, so that the guide box 210 moves up and resets to conflict with the heat conduction plate 73, thereby completing the automatic cleaning of several electric heaters 72. The scale on the outside of several electric heaters 72 can be cleaned quickly and conveniently, and through the coordination of the guide box 1 210, the flow control component, several guide box 215, several hydraulic expansion parts 216, the liquid supply component and other structures, the soaking, softening and scraping of the scale on the outside of the electric heater 72 can be achieved under the premise of adding a small amount of descaling agent, and the scale removal work on the outside of several electric heaters 72 can be completed automatically, thereby reducing time cost investment, reducing the difficulty of steam generator maintenance work, and reducing labor cost investment.
