Description

Technical Field

[0001] The utility model relates to a steam boosting system for supporting a steam generator, belonging to the technical field of heat exchange machinery. Background Art

[0002] The steam generator under normal pressure generates low-pressure steam, and the generated steam pressure is generally about 0.1 Mpa. High-pressure steam is required in many occasions, which limits the use of such steam generators. If high-pressure steam is to be output, the steam needs to be boosted. The common steam boosting device is a worm gear booster, and there are also various technical solutions related to worm gear boosting disclosed in Chinese patents, such as a steam turbine supercharger disclosed in CN110307044A, an exhaust gas steam turbocharging system disclosed in CN1987064A, etc. However, the worm gear boosting mechanism has a high price and it is difficult to avoid oil. CN115234525A discloses a multi-gas-source steam boosting device, but it itself requires a high-pressure gas source. Therefore, developing a simple and practical steam boosting system can enable the steam generator under normal pressure to meet the requirement of outputting high-pressure steam. Summary of the Invention

[0003] The purpose of the utility model is to meet the need of high-pressure steam output and provide a steam boosting system.

[0004] To achieve the purpose of the utility model, the following technical solution is adopted: A steam boosting system includes an input tank connected to the incoming steam. A steam input pipe is connected to the input tank. The output tank is communicated with the input tank through a connecting pipe. The connecting pipe is located at the upper parts of the output tank and the input tank. A check valve is installed on the connecting pipe, and the check valve enables the steam to only flow from the input tank to the output tank. A steam output pipe and a pressure gauge are connected to the output tank. Two pipelines are connected to the bottoms of the input tank and the output tank. Booster pumps are connected to both pipelines. An electric control valve is installed in front of the booster pump. Water is contained in the input tank and the output tank. One booster pump pumps water from the input tank into the output tank, and the other booster pump pumps water from the output tank to the input tank. A liquid level gauge is connected to the output tank. A water replenishing pipe is connected to the bottom of the output tank. A sewage discharge valve is connected to the bottom of the input tank or the output tank, or sewage discharge valves are connected to the bottoms of both the input tank and the output tank. The booster pumps and the electric control valves are all connected to a controller.

[0005] Further, the diameters of the input tank and the output tank are the same. Before starting, the liquid levels of the output tank and the input tank are the same.

[0006] Further, the steam output pipe is connected to the top surface of the output tank, and the steam input pipe is connected to the side wall of the input tank.

[0007] The positive and beneficial technical effects of the present utility model are as follows: The structure of this system is relatively simple, with low cost, and it avoids oil content and can achieve the pressurization of steam. Specific explanations will be given in combination with the specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 3 is the internal schematic diagram of the present utility model. SPECIFIC EMBODIMENTS

[0011] In order to more fully explain the implementation of the present utility model, implementation examples of the present utility model are provided. These implementation examples are only elaborations of the present utility model and do not limit the scope of the present utility model.

[0012] With reference to the accompanying drawings, the present utility model will be further explained in detail. The reference numerals in the drawings are: 1: input tank; 2: output tank; 3: steam input pipe; 4: steam output pipe; 5: connecting pipe; 6: check valve; 7: booster pump A; 8: electric control valve A; 9: booster pump B; 10: electric control valve B; 11: liquid level gauge; 12: water supply pipe; 13: drain valve; 14: water.

[0013] As shown in the accompanying drawings, a steam pressurization system includes an input tank 1 connected to the incoming steam. A steam input pipe 3 is connected to the input tank 1, and the steam input pipe is connected to the side wall of the input tank. The output tank 2 is communicated with the input tank 1 through a connecting pipe 5. The connecting pipe 5 is located at the upper parts of the output tank and the input tank. A check valve 6 is installed on the connecting pipe, and the check valve enables the steam to only flow from the input tank to the output tank. In this embodiment, the diameters of the input tank and the output tank are the same. A steam output pipe 3 and a pressure gauge (not shown in the figure) are connected to the output tank. The steam output pipe is connected to the top surface of the output tank. Two pipelines are connected to the bottoms of the input tank and the output tank, and booster pumps are connected to both pipelines. Electric control valves are installed in front of the booster pumps. In the figure, booster pump A 7 and electric control valve A 8 are located on one pipeline; booster pump B 9 and electric control valve B 10 are located on the other pipeline. Water 14 is contained in the input tank and the output tank. Before starting, the liquid levels of the output tank and the input tank are the same. One booster pump A pumps water from the input tank into the output tank, and the other booster pump B pumps water from the output tank to the input tank. A liquid level gauge 11 is connected to the output tank. A water supply pipe 12 is connected to the bottom of the output tank. A drain valve is connected to the bottom of the input tank or the output tank, or drain valves are connected to the bottoms of both the input tank and the output tank. In this embodiment, the drain valve is connected to the bottom of the output tank. The booster pumps and the electric control valves are all connected to the controller.

[0014] The booster pump in this system can be ZWWH-0.75-1.25 or ZWWH-1.0-1.25. After testing, the two booster pumps work alternately, each pump works for 2 minutes, the steam inlet pressure is less than 0.1Mpa, and the outlet pressure can reach more than 0.5Mpa.

[0015] In this system, the liquid levels in the input tank and the output tank are the same at the beginning. Steam first enters the input tank, and then enters the output tank through the connecting pipe and the check valve. The booster pump A is started for a certain time to pump water into the output tank. At this time, the space in the output tank is compressed, and the steam pressure increases. The valve on the steam output tank can output high-pressure steam. Then the booster pump B is started for the same time to pump water from the output tank into the input tank, and the steam flows from the input tank into the output tank. The above process is repeated to increase the pressure in the output tank. In this system, since the two booster pumps have the same startup time and the liquid levels in the input tank and the output pipe are the same before startup, it is only necessary to install a liquid level gauge on the output tank to obtain water level information. Since the steam temperature is high, it will exchange heat with water and take away some water, and will also lose some steam heat, but under continuous and stable operation, it will not affect the output of high-pressure steam.

[0016] After describing the implementation mode of the utility model in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of the technical solution of the utility model, and the utility model is not limited to the implementation mode of the examples given in the specification.
