Description

Technical Field

[0001] This utility model relates to the field of combined heating network heater technology, and in particular to a high-efficiency, low-noise combined heating network heater. Background Technology

[0002] Heat exchangers are key equipment in heat network systems and are one of the main auxiliary equipment in thermal power plants. Their main function is to use steam extracted from the steam turbine or steam drawn from the boiler (heating medium) to heat the circulating water in the hot water supply system to meet the requirements of heating users. According to the heating medium, heat exchangers can be divided into two types: steam-water heat exchangers and water-water heat exchangers.

[0003] In the prior art, Chinese Patent No. CN 220729028 U discloses a heat network heater, including a heater assembly and a gas-push diffuser assembly. One end of the heater assembly is provided with a bottom support, and the top of the bottom support is provided with a bidirectional gas supply assembly. A fixed pipe is inserted into the inlet end of the tube bundle heat exchanger and pushed inward. The gas supply pump can inject gas into the inward gas supply pipe at regular intervals. The auxiliary force drives the descaling pipe to move into the tube bundle heat exchanger, making it easier to push the descaling pipe to a certain position. Then, the gas supply pump injects gas into the winding pipe and the descaling pipe, causing it to drive the descaling scraper to expand outward until the descaling scraper reaches the inside of the tube bundle heat exchanger. Then, the descaling pipe is pulled back and forth to clean the scale deposited in the tube bundle heat exchanger, thereby completing the scale cleaning work inside the tube bundle heat exchanger.

[0004] The heat network heater in this patent does not have a noise reduction structure. Under low load conditions, due to insufficient steam supply, the shell side of the heat network heater is prone to negative pressure operation. At this time, the steam density is low, the specific volume is large, and the steam volume flow rate is too high, which causes the equipment noise to exceed the standard. Utility Model Content

[0005] In view of the technical problem mentioned in the background art that the heat network heater in the patent does not have a noise reduction structure, this utility model provides a high-efficiency, low-noise combined heat network heater.

[0006] The technical solution adopted by this utility model is: a high-efficiency, low-noise combined heat exchanger heater, including a first pipe and a second pipe, the first pipe and the second pipe being detachably and fixedly connected, a heat exchange component being provided inside the first pipe, a fixed pipe being fixedly connected to one side of the bottom of the first pipe, a first feed pipe being fixedly connected to the bottom of the fixed pipe, a first discharge pipe being fixedly connected to one side of the top of the first pipe, a second feed pipe and a second discharge pipe being fixedly connected to both ends of the second pipe respectively, a first regulating pipe being fixedly connected inside the fixed pipe, a plurality of first through holes being provided on the outside of the first regulating pipe, a second regulating pipe being provided inside the first regulating pipe, a plurality of second through holes being provided on the outside of the second regulating pipe, and a pressure regulating component being provided inside the second regulating pipe, the pressure regulating component being used to drive the second regulating pipe to rotate.

[0007] The present invention is further configured such that the heat exchange assembly includes a baffle plate fixedly connected inside the second pipe, a fixing plate fixedly connected inside one end of the first pipe, and multiple sets of U-shaped tubes fixedly connected inside the first pipe. Multiple sets of guide plates are fixedly connected inside the first pipe, and the two ends of the U-shaped tubes are respectively located on the upper and lower sides of the baffle plate.

[0008] A further feature of this invention is that the diameter of the first through hole and the diameter of the second through hole are equal.

[0009] The present invention is further configured such that the pressure regulating assembly includes a push plate disposed in the second regulating tube, protrusions fixedly connected to both sides of the push plate, and inclined grooves disposed on both sides inside the second regulating tube. The protrusions are engaged in the inclined grooves. A slide rod is fixedly connected to one end of the push plate. A fixing sleeve is fixedly connected inside the first regulating tube. A spring is connected between the fixing sleeve and the slide rod.

[0010] A further feature of this invention is that the two ends of the second regulating tube are open structures.

[0011] A further feature of this invention is that both the first pipe and the second pipe are covered with sound-insulating cotton.

[0012] The beneficial effects of this utility model are as follows: In this utility model, hot steam is transported into the first feed pipe. Driven by the steam pressure, the second regulating pipe can be rotated by the pressure regulating component. When the second regulating pipe rotates, the second through hole aligns with the first through hole. The larger the angle of rotation of the second regulating pipe, the larger the area of ​​overlap between the first and second through holes. That is to say, when the heating steam reaches a certain pressure, the steam can enter the first pipe through the first and second through holes. Thus, through the setting of the push plate and spring, the pressure can be automatically stabilized under unstable hot steam pressure and low load conditions. The heating steam enters the first pipe through the first and second through holes, reducing noise. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described below.

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a high-efficiency and low-noise combined heat network heater, including a first pipe 1 and a second pipe 2, the first pipe 1 and the second pipe 2 are detachably and fixedly connected, a heat exchange component is provided inside the first pipe 1, and sound insulation cotton is covered on the outside of both the first pipe 1 and the second pipe 2.

[0026] In the specific design, the heat exchange assembly includes a baffle 8 fixedly connected inside the second pipe 2, a fixed plate 9 fixedly connected inside one end of the first pipe 1, and multiple sets of U-shaped tubes 10 fixedly connected inside the first pipe 1. Multiple sets of guide plates 11 are fixedly connected inside the first pipe 1, and the two ends of the U-shaped tubes 10 are located on the upper and lower sides of the baffle 8, respectively.

[0027] A fixed pipe 7 is fixedly connected to one side of the bottom of the first pipe 1. A first feed pipe 3 is fixedly connected to the bottom of the fixed pipe 7. A first discharge pipe 4 is fixedly connected to one side of the top of the first pipe 1. A second feed pipe 5 and a second discharge pipe 6 are fixedly connected to both ends of the second pipe 2, respectively. A first regulating pipe 12 is fixedly connected inside the fixed pipe 7. The outside of the first regulating pipe 12 is provided with multiple sets of first through holes 13. A second regulating pipe 14 is provided inside the first regulating pipe 12. The two ends of the second regulating pipe 14 are open structures. The outside of the second regulating pipe 14 is provided with multiple sets of second through holes 15. The diameter of the through hole 13 is equal to the diameter of the second through hole 15. The second regulating pipe 14 is also provided with a pressure regulating component. The pressure regulating component is used to drive the second regulating pipe 14 to rotate. When the second regulating pipe 14 rotates, the second through hole 15 can correspond to the first through hole 13. The larger the angle of rotation of the second regulating pipe 14, the larger the area of ​​overlap between the first through hole 13 and the second through hole 15. That is to say, when the heating steam reaches a certain pressure, the steam can enter the first pipe 1 through the first through hole 13 and the second through hole 15.

[0028] The above technical solution is explained as follows: the feed pipe is used to enter cold material, the second discharge pipe 6 is used to discharge the cold material after heat exchange, and the first feed pipe 3 is used to enter hot steam.

[0029] Specifically, the pressure regulating assembly includes a push plate 16 disposed in the second regulating tube 14, protrusions 21 fixedly connected to both sides of the push plate 16, and inclined grooves 20 disposed on both sides inside the second regulating tube 14. The protrusions 21 are engaged in the inclined grooves 20. A slide rod 19 is fixedly connected to one end of the push plate 16. A fixing sleeve 17 is fixedly connected inside the first regulating tube 12. A spring 18 is connected between the fixing sleeve 17 and the slide rod 19.

[0030] The above technical solution is explained as follows: Hot steam is delivered into the first feed pipe 3. Under the pressure of the steam, the push plate 16 will slide. The sliding of the push plate 16 compresses the spring 18, realizing the floating of the push plate 16. At the same time, the sliding of the push plate 16 can drive the protrusion 21 to slide in the inclined groove 20. Due to the inclination of the inclined groove 20, the second regulating pipe 14 can be driven to rotate when the push plate 16 slides. When the second regulating pipe 14 rotates, the second through hole 15 can be aligned with the first through hole 13. The larger the angle of rotation of the second regulating pipe 14, the larger the area of ​​overlap between the first through hole 13 and the second through hole 15. That is to say, when the heating steam reaches a certain pressure, the steam can enter the first pipe 1 through the first through hole 13 and the second through hole 15.

[0031] The usage method of this embodiment is as follows:

[0032] Hot steam is delivered into the first feed pipe 3. Under the pressure of the steam, the push plate 16 slides. The sliding of the push plate 16 compresses the spring 18, causing the push plate 16 to float. At the same time, the sliding of the push plate 16 can drive the protrusion 21 to slide in the inclined groove 20. Due to the inclination of the inclined groove 20, the sliding of the push plate 16 can drive the second regulating pipe 14 to rotate. When the second regulating pipe 14 rotates, the second through hole 15 can correspond to the first through hole 13. The larger the rotation angle of the second regulating pipe 14, the larger the area of ​​overlap between the first through hole 13 and the second through hole 15. That is to say, when the heating steam reaches a certain pressure, the steam can enter the first pipe 1 through the first through hole 13 and the second through hole 15. Thus, in this embodiment, the push plate 16 and the spring 18 can automatically stabilize the pressure under unstable hot steam pressure and low load conditions. The heating steam enters the first pipe 1 through the first through hole 13 and the second through hole 15, reducing noise.
