Description

Technical Field

[0001] This utility model relates to the field of steam, specifically a steam pressurization device. Background Technology

[0002] In existing chemical production plants, the rational use and recovery of steam is a key factor in energy conservation and consumption reduction. Steam is also divided into many grades, including high steam, medium steam, and low steam. Different operating conditions require different grades and qualities of steam. Low-pressure steam is often not used rationally, which will lead to energy waste. For example, low-pressure waste heat boilers in nitric acid plants, low-pressure waste boilers in synthetic ammonia plants, low-pressure flash tanks in ammonium nitrate plants, and low-pressure steam produced as a by-product of melamine plants may be directly vented due to their low pressure, or the heat may be directly cooled by condensers (including but not limited to water coolers, air coolers, evaporative air coolers, etc.) and discharged into the main steam.

[0003] In the current steam pressurization process, a separator is needed to separate the steam into liquid and vapor. However, in the current separator, the low-vapor inlet pipe is directly inserted into the separator tank, and a filter screen is installed at the top of the tank to achieve steam-liquid separation. In this type of separator, because the low-vapor inlet pipe concentrates the steam supply to the center of the filter screen, the separated aqueous solution blocks the mesh of the filter screen. This results in poor steam-liquid separation effect of the steam pressurization device, thus affecting the use of the steam pressurization device. Utility Model Content

[0004] The purpose of this invention is to provide a steam pressurization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steam pressurization device includes a low-steam inlet pipe. One end of the low-steam inlet pipe is connected to a first steam generating device, a second steam generating device, a third steam generating device, and a fourth steam generating device. The other end of the low-steam inlet pipe is connected to a vapor-liquid separator. The vapor-liquid separator includes a tank body with a steam outlet at the top. The steam outlet is connected to a compressor via a connecting pipe. The compressor is connected to a desuperheater via a connecting pipe. The desuperheater is connected to an interstage separator via a connecting pipe. The interstage separator is connected to a first low-steam user, a second low-steam user, and a third low-steam user via the low-steam outlet pipe. A conical steam storage device is fixedly installed inside the tank body. The conical steam storage hood has a sealing cover at its bottom. A rotating motor is fixedly installed inside the sealing cover, and a rotating rod is mounted on the motor shaft. An exhaust pipe is opened inside the rotating rod. Several steam inlets are evenly spaced at the bottom of the exhaust pipe inside the conical steam storage hood. Support frames are fixedly installed at the four corners of the top of the rotating rod above the conical steam storage hood. Nozzles are fixedly installed on the support frames, and the bottom of the nozzles are connected to the exhaust pipe through a steam injection pipe. A conical filter bucket is fixedly installed inside the tank above the nozzles. Several ventilation holes are opened on the conical filter bucket. A filter plate is installed inside the tank at the top of the conical filter bucket. Several liquid drainage components are evenly spaced at the bottom of the conical filter bucket.

[0007] Preferably, the low-evaporation pipeline inlet pipe is sequentially equipped with a flow control regulating valve, a first flow meter, a first pressure detection element, and a first thermometer.

[0008] Preferably, a drain outlet is provided at the bottom of the tank.

[0009] Preferably, the drainage assembly includes drainage channels equally spaced at the bottom outer end of the conical filter hopper, and a drainage pipe is provided at the bottom of the drainage channel.

[0010] Preferably, the desuperheater is equipped with a spray nozzle inside, the outer end of which is connected to the steam condensate pipe via a connecting pipe, and a condensate regulating valve and a condensate flow meter are installed on the connecting pipe between the spray nozzle and the steam condensate pipe.

[0011] Preferably, a second pressure detection element and a second thermometer are sequentially installed on the low-evaporation pipeline's main discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a rotating motor to drive a rotating rod to rotate a support frame, which in turn drives the nozzle to rotate. Water vapor enters the conical steam storage hood through a low-evapor pipe and a collection inlet pipe. Water vapor then enters the exhaust pipe through an inlet nozzle and is sprayed onto the nozzle through a spray pipe. The nozzle evenly adds water vapor into the groove at the bottom of the conical filter bucket. Water vapor is also evenly added into the filter plate through ventilation holes. The filter plate filters and separates the aqueous solution in the water vapor. The aqueous solution is discharged through a drain assembly. This facilitates rapid vapor-liquid separation of the water vapor solution, thus facilitating steam pressurization. The steam after vapor-liquid separation enters the compressor for pressurization. The pressurized water vapor is then cooled by a desuperheater to maintain its temperature. After being graded by an interstage separator, the graded water vapor is discharged to users with different needs through a low-evapor pipe collection outlet pipe, thus facilitating the use of steam.

Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figure 1-3 In this embodiment of the present invention, a steam pressurization device includes a low-steam pipeline inlet pipe 1. One end of the low-steam pipeline inlet pipe 1 is connected to a first steam generating device 18, a second steam generating device 19, a third steam generating device 20, and a fourth steam generating device 21, respectively. The other end of the low-steam pipeline inlet pipe 1 is connected to a vapor-liquid separator 6. The vapor-liquid separator 6 includes a tank body 61, with a steam outlet 62 at the top. The steam outlet 62 is connected to a compressor 7 via a connecting pipe. The compressor 7 is connected to a desuperheater 8 via a connecting pipe. The desuperheater 8 is connected to an interstage separator 10 via a connecting pipe. The interstage separator 10 is connected to a first low-steam user 14, a second low-steam user 15, and a third low-steam user 16 via a low-steam pipeline outlet pipe 13, respectively. A conical steam storage hood 64 is fixedly installed inside the tank body 61. 4. A sealing cover 65 is provided at the bottom of the interior. A rotating motor 66 is fixedly installed inside the sealing cover 65. A rotating rod 67 is installed on the motor shaft of the rotating motor 66. A steam exhaust pipe 68 is opened inside the rotating rod 67. Several steam inlets 69 are evenly spaced at the bottom of the steam exhaust pipe 68 located inside the conical steam storage cover 64. A support frame 610 is fixedly installed at the four corners of the top of the rotating rod 67 located above the conical steam storage cover 64. A nozzle 611 is fixedly installed on the support frame 610. The bottom of the nozzle 611 is connected to the steam exhaust pipe 68 through a steam injection pipe 612. A conical filter bucket 613 is fixedly installed inside the tank body 61 located above the nozzle 611. Several ventilation holes 614 are opened on the conical filter bucket 613. A filter plate 615 is provided inside the tank body 61 located at the top of the conical filter bucket 613. Several liquid drainage components are evenly spaced at the bottom of the conical filter bucket 613.

[0021] This invention incorporates steam generated by the first steam generator 18, the second steam generator 19, the third steam generator 20, and the fourth steam generator 21 into the conical steam storage hood 64 inside the vapor-liquid separator 6 via a low-steam concentrator inlet pipe 1. The steam enters the exhaust pipe 68 through the inlet nozzle 69 and is then injected into the nozzle 611 via the injection pipe 612. During the injection process, the nozzle 611 is driven by a rotating motor 66 to rotate a rotating rod 67, which in turn rotates the support frame 610. The support frame 610 then drives the nozzle 611 to rotate. The rotating steam injection process involves nozzle 611 uniformly injecting steam into the conical filter bucket 613, allowing water vapor to be evenly added into the filter plate 615. The filter plate 615 filters and separates the aqueous solution in the water vapor, which is then discharged through the drain assembly. The water vapor is supplied to the compressor 7 through the steam outlet 62, which pressurizes the water vapor. The pressurized water vapor then enters the interstage separator 10 for vapor-liquid separation and is discharged sequentially through the low-vapor pipeline and the discharge pipe 13. This process achieves the pressurization of the water vapor.

[0022] See Figure 1 In one embodiment of this utility model, a flow control regulating valve 2, a first flow meter 3, a first pressure detection element 4, and a first thermometer 5 are sequentially installed on the low-evaporation pipeline inlet pipe 1. By setting the flow control regulating valve 2, the first flow meter 3, the first pressure detection element 4, and the first thermometer 5 on the low-evaporation pipeline inlet pipe 1, the flow rate of water vapor inside the low-evaporation pipeline inlet pipe 1 can be controlled and the temperature of the water vapor can be measured, thereby facilitating the monitoring of the incoming water vapor.

[0023] See Figure 2 In one embodiment of this utility model, a drain outlet 63 is provided at the bottom of the tank 61, which allows the separated aqueous solution to be discharged.

[0024] See Figure 3 In one embodiment of this utility model, the drainage component includes drainage grooves 616 equally spaced at the bottom outer end of the conical filter hopper 613. A drainage pipe 617 is provided at the bottom of the drainage groove 616. Water vapor enters the filter plate 615, and the filter holes on the filter plate 615 filter the liquid in the water vapor. The liquid flows downward with gravity into the drainage groove 616 at the bottom of the conical filter hopper 613 and is discharged through the drainage pipe 617. This facilitates the separation and treatment of the aqueous solution inside the water vapor.

[0025] See Figure 1In one embodiment of this utility model, the desuperheater 8 is provided with a spray nozzle 93. The outer end of the spray nozzle 93 is connected to the steam condensate pipe 9 through a connecting pipe. A condensate regulating valve 91 and a condensate flow meter 92 are provided on the connecting pipe between the spray nozzle 93 and the steam condensate pipe 9. The steam condensate pipe 9 cools the water vapor inside the desuperheater 8 through the connecting pipe and the spray nozzle 93. This can cool the pressurized water vapor. The condensate regulating valve 91 and the condensate flow meter 92 control the cooling of the spray nozzle 93.

[0026] See Figure 1 In one embodiment of this utility model, a second pressure detection element 11 and a second thermometer 12 are sequentially installed on the low-evaporation pipeline collection and discharge pipe 13. The setting of the second pressure detection element 11 and the second thermometer 12 can facilitate the detection and processing of water vapor pressure and temperature after pressure division.

[0027] See Figure 1 In one embodiment of this utility model, a circulation pipe is installed on the connecting pipes on both sides of the compressor 7, and an anti-kick control regulating valve 17 is installed on the circulation pipe. The anti-kick control regulating valve 17 is set so that if the inlet steam volume of the compressor 7 is too small, the outlet pressure of the compressor 7 will be too high. The high outlet pressure steam can be returned to the inlet of the compressor 7 through the anti-kick control regulating valve 17, which can meet the requirements of maintaining stable steam pressure output and stable operation of the compressor.

[0028] Working Principle: This invention collects steam generated inside various steam-generating devices through a low-steam pipe and introduces it into the conical steam storage hood 64 inside the steam-liquid separator 6. Water vapor is supplied to the nozzles 611 through the steam inlet 69, exhaust pipe 68, and injection pipe 612. The rotating motor 66 drives the rotating rod 67, causing the four corner nozzles 611 to rotate and inject steam. This ensures that water vapor is evenly injected into the groove at the bottom of the conical filter hopper 613, and then enters the filter plate 615 through the ventilation holes 614, where the filter plate 615 filters the water vapor. The filtered steam is introduced into the compressor tank 7 through the steam outlet 62 and the connecting pipe for air compression and pressurization. The temperature of the compressed steam will also increase accordingly. The steam is then introduced into the desuperheater 8 through the connecting pipe. The aqueous solution inside the steam condensate pipe 9 is introduced into the spray nozzle 93 through the connecting pipe to cool the steam inside the desuperheater 8. The treated steam is then introduced into the interstage separator 10 through the connecting pipe for pressure separation. The separated steam is then supplied to each low-steam user through the low-steam pipeline and the discharge pipe 13. This allows for safe pressurization of the steam, making it convenient for steam use.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
