Description

Technical Field

[0001] The utility model relates to the fields of industrial production and energy utilization, in particular to a steam temperature and pressure raising system. Background Art

[0002] The existing 2.8MPa(G) medium-pressure saturated steam is the by-product steam of Fischer-Tropsch synthesis, and the steam temperature is only 232 degrees. Other grades of steam are generated by boilers, and the steam grades do not match. If the steam generated by the boiler is used, the cost of pipeline use will increase, and it will also cause waste of steam (excess heat cannot be consumed and cooling is required). The amount of steam required by the downstream device is small, and the temperature is required to be above 230 degrees. During the long-distance steam pipeline transportation process, the steam will be affected by pressure and temperature, resulting in condensate loss and steam heat loss. In addition, the internal pressure of the pipeline is reduced, and the condensate is excessive, which is prone to pipeline liquid hammer. Conventional insulation measures can no longer meet the production and operation requirements, and the steam quality needs to be improved urgently. Conventional steam use generally reduces the temperature and pressure of high-pressure steam and reduces the grade of use, which not only wastes steam energy but also increases production consumption.

[0003] Therefore, it is necessary to provide a new steam temperature and pressure raising system to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a steam temperature and pressure raising system.

[0005] The steam temperature and pressure raising system provided by the utility model comprises: a base plate, a pressure matcher, a medium-pressure pipeline, a high-pressure pipeline, a desuperheater, a water inlet pipe and a discharge pipe. A pressure matcher is arranged on the top of the base plate, and a medium-pressure pipeline and a high-pressure pipeline are arranged on the top of the base plate. One end of the medium-pressure pipeline and one end of the high-pressure pipeline are respectively connected to the input end corresponding to the pressure matcher, the output end of the pressure matcher is connected to the desuperheater through a pipeline, the input end of the desuperheater is connected to the water inlet pipe, and the output end of the desuperheater is connected to the discharge pipe.

[0006] Preferably, the water inlet pipe and the outlet pipe are both equipped with a plurality of test gauges.

[0007] Preferably, support frames are equidistantly sleeved on the outside of the water inlet pipe and the outside of the outlet pipe, and the support frames are fixedly connected to the top of the base plate.

[0008] Preferably, 2.8 MPa (G) medium-pressure saturated steam is passed through the medium-pressure pipeline.

[0009] Preferably, a small amount of medium-pressure superheated steam of 5.0 MPa (G) and 395° C. is passed through the interior of the high-pressure pipeline.

[0010] Preferably, deoxygenated water at 6.0 MPa (G) and 120° C. is passed through the water inlet pipe.

[0011] Preferably, a plurality of flow nozzles are provided at the connection between the high-pressure pipeline and the pressure matcher, and the flow nozzles are used to control the inlet flow of the introduced superheated steam.

[0012] Compared with the related art, the steam temperature and pressure raising system provided by the utility model has the following beneficial effects:

[0013] The utility model provides a steam temperature and pressure raising system, which achieves steam temperature and pressure raising by mixing and compressing low-pressure steam and high-pressure superheated steam in a pressure matcher, thereby improving the energy density and availability of the steam. Compared with directly generating high-temperature and high-pressure steam, this processing method is more energy-efficient and improves energy utilization efficiency. During the temperature and pressure raising process, the system uses deoxygenated water as a cooling medium, reduces the temperature of the steam through heat exchange, and avoids energy waste and environmental pollution that may be caused by directly discharging high-temperature steam. This processing method meets the requirements of environmental protection and energy saving, and is conducive to sustainable development. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

The pressure matcher 2 is provided on the top of the base plate 1, and the medium-pressure pipeline 3 and the high-pressure pipeline 4 are provided on the top of the base plate 1. One end of the medium-pressure pipeline 3 and one end of the high-pressure pipeline 4 are respectively connected to the corresponding input end of the pressure matcher 2, the output end of the pressure matcher 2 is connected to the desuperheater 5 through a pipeline, the input end of the desuperheater 5 is connected to the water inlet pipe 6, and the output end of the desuperheater 5 is connected to the discharge pipe 7.

[0021] See also Figures 1 to 3 , the water inlet pipe 6 and the discharge pipe 7 are both equipped with a number of detection meters 8;

[0022] See also Figures 1 to 3 , support frames 9 are equidistantly sleeved on the outside of the water inlet pipe 6 and the outside of the discharge pipe 7, and the support frames 9 are fixedly connected to the top of the base plate 1;

[0023] See also Figures 1 to 3 , 2.8MPa(G) medium-pressure saturated steam is passed through the medium-pressure pipeline 3;

[0024] See also Figures 1 to 3 A small amount of medium-pressure superheated steam of 5.0 MPa (G) and 395°C is passed through the high-pressure pipeline 4;

[0025] See also Figures 1 to 3 , deoxygenated water at 6.0MPa(G) and 120℃ is passed through the water inlet pipe 6;

[0026] See also Figures 1 to 3 A plurality of flow nozzles are provided at the connection between the high-pressure pipeline 4 and the pressure matcher 2, and the flow nozzles are used to control the inlet flow of the introduced superheated steam;

[0027] The working principle of the steam temperature and pressure raising system provided by the utility model is as follows: the steam temperature and pressure raising system is mainly composed of key components such as a base plate 1, a pressure matching device 2, a medium-pressure pipeline 3, a high-pressure pipeline 4, a desuperheater 5, a water inlet pipe 6 and a discharge pipe 7, and these components work together to ensure that the steam can achieve efficient temperature and pressure raising;

[0028] First, the medium-pressure pipeline 3 is responsible for introducing 2.8MPa(G) medium-pressure saturated steam into the system as the steam source to be treated, and at the same time, the high-pressure pipeline 4 introduces a small amount of 5.0MPa(G) 395℃ medium-pressure superheated steam into the system as driving steam;

[0029] Next, these steams enter the corresponding input ends of the pressure matcher 2 respectively. Inside the pressure matcher 2, the steam to be processed is sucked in by the negative pressure generated by the high-speed flow of the driving steam. Through the mixing and compression process, the steam to be processed is heated and the pressure is increased by the driving steam in the pressure matcher 2, thereby reaching the required temperature and pressure level.

[0030] In order to ensure that the temperature of the steam can meet specific requirements after being raised, the system is equipped with a desuperheater 5. The steam after being raised in temperature and pressure by the pressure matcher 2 enters the desuperheater 5. At the same time, the water inlet pipe 6 introduces 6.0MPa(G) 120℃ deoxygenated water into the desuperheater 5 as a cooling medium. In the desuperheater 5, the deoxygenated water exchanges heat with the high-temperature steam to reduce the temperature of the steam to the set value.

[0031] In order to monitor the operating status of the system in real time, several test meters 8 are installed on the water inlet pipe 6 and the outlet pipe 7 to monitor key parameters such as the flow rate and temperature of water and steam. The data of these test meters 8 provide important feedback information for the system to ensure the stable operation of the system;

[0032] In addition, in order to support and fix the pipelines, support frames 9 are equidistantly sleeved on the outside of the water inlet pipe 6 and the outlet pipe 7. These support frames 9 are fixedly connected to the top of the base plate 1, which effectively prevents the pipelines from being displaced or damaged due to vibration or external force;

[0033] Finally, the steam after temperature increase and pressure increase and temperature adjustment is output through the exhaust pipe 7 and supplied to the downstream equipment. The working process of the whole system realizes the efficient temperature increase and pressure increase of the steam and meets the needs of industrial applications.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
