Technical Field

[0001] The invention relates to the technical field of steam-water separation, in particular to a steam-water separator. Background Art

[0002] A boiler is an energy conversion device that uses the heat released by fuel combustion or other energy sources (such as electricity, solar energy, etc.) to heat water or other working fluids to reach or maintain a certain temperature and pressure. In the process of using a boiler, for large boilers, steam and water can be easily separated, but for small boilers, steam and water separation is difficult and prone to leakage, so a steam-water separator is needed.

[0003] When the steam-water separator is in use, the steam-water mixture is passed into the separator, and the mixture contacts the cyclone plate inside the separator to separate the steam and water, wherein the water is discharged through the lower end pipe, and the relatively dry steam is output as a driving source. However, in the existing steam-water separator, the internal structure of the separator is simple, and the steam-water separation is only performed by the cyclone plate, and the separation effect is average, and the output steam still has a large humidity, which further affects the use effect of the steam.

[0004] Previously, boilers were relatively large, so steam-water separation was easy to handle. Now, for boilers smaller than 30L, steam-water separation is more difficult and is prone to leaking outside, which has always been a difficult problem to solve. Summary of the invention

[0005] The main purpose of the present invention is to provide a steam-water separator which can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A steam-water separator comprises a separator body, wherein an upper head is provided at the upper end of the separator body, and a lower head is provided at the lower end of the separator body, a separation inner sleeve is provided inside the separator body, and an inclined partition plate and a spiral separation guide plate are installed inside the separator body, a liquid separation plate is provided at the inner bottom end of the separator body, and a steam inlet pipe and a steam outlet pipe are installed at the upper end of the separator body, an auxiliary separation structure is provided inside the separator body, and a liquid guide pipe is provided inside the separator body.

[0011] Preferably, the auxiliary separation structure includes a condensation guide assembly and a centrifugal assembly, the upper end of the condensation guide assembly passes through the upper head, and the condensation guide assembly is connected to the centrifugal assembly, and the centrifugal assembly is located directly above the separation inner sleeve.

[0012] Preferably, the condensation guide assembly includes an arc-shaped cover, a cavity, a water inlet pipe and a water outlet pipe, the cavity is opened on the arc-shaped cover, the water inlet pipe is fixed at the edge of the arc-shaped cover, the water outlet pipe is installed on the top of the arc-shaped cover, and the water inlet pipe and the water outlet pipe are connected to the cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the steam-water separator, by arranging a separation inner sleeve, an inclined partition, a spiral separation guide plate, a liquid separation plate and an auxiliary separation structure inside the separator body, can use the spiral separation guide plate to perform preliminary separation of steam and water, and use the inclined partition plate in conjunction with the auxiliary separation structure to further separate the steam and water, thereby improving the steam-water separation effect and increasing the steam quality; a cooling guide assembly and a centrifugal assembly are arranged in the auxiliary separation structure; the steam and water blown out of the separation inner sleeve exert a force on the turbine blades, and the turbine blades rotate to exert centrifugal force, so that part of the steam and water diffuses to the surroundings, and part of the steam and water passes through the turbine blades to contact the condensation guide assembly, thereby increasing the steam-water separation efficiency and at the same time blocking the water droplets on the condensation guide assembly to prevent the water droplets from falling from the separation inner sleeve and not affecting the normal transportation of the steam and water, thereby further ensuring the separation efficiency; cold water can be selectively injected into the cavity in the condensation guide assembly to facilitate rapid condensation of moisture in the steam and water and improve the efficiency of drying steam.

[0015] After the soda-water mixture comes in, part of it collides with the inclined partition, and the water flows down along the liquid guide tube; part of it collides with the spiral separation guide plate, and due to the force of gravity, the water continues to flow downward and flows down through the liquid separator plate; the soda-water mixture that first goes downward and then moves from bottom to top collides with the inclined partition and is separated.

[0016] The steam quality is good and the water can be recycled. For boilers less than 30L, it is relatively easy to separate steam and water, and it will not leak to the outside. Dual effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 5 As shown, a steam-water separator comprises a separator body 1, an upper end cap 2 is provided at the upper end of the separator body 1, a lower end cap 3 is provided at the lower end of the separator body 1, a separation inner sleeve 4 is provided inside the separator body 1, an inclined partition plate 8 and a spiral separation guide plate 10 are installed inside the separator body 1, a liquid separation plate 11 is provided at the bottom end of the separator body 1, a steam inlet pipe 5 and a steam outlet pipe 6 are installed at the upper end of the separator body 1, an auxiliary separation structure 9 is provided inside the separator body 1, and a liquid guide pipe 14 is provided inside the separator body 1. The upper end cap 2 and the lower end cap 3 are fixedly mounted on the separator body 1, and the auxiliary separation structure 9 is mounted on the upper end cap 2. By arranging the separation inner sleeve 4, the inclined partition plate 8, the spiral separation guide plate 10, the liquid separation plate 11 and the auxiliary separation structure 9 inside the separator body 1, the spiral separation guide plate 10 can be used to perform preliminary separation of steam and water, and the inclined partition plate 8 and the auxiliary separation structure 9 can be used to further separate steam and water, thereby improving the steam-water separation effect and increasing the steam quality.

[0021] The ends of the steam inlet pipe 5 and the steam outlet pipe 6 are provided with connecting flanges 12, and the liquid separator plate 11 is provided with through holes 13. The two ends of the liquid guide pipe 14 respectively penetrate the inclined partition plate 8 and the liquid separator plate 11, and the separation inner sleeve 4 is fixedly connected to the inclined partition plate 8 and the spiral separation guide plate 10. The lower end of the lower head 3 is fixed with a drain pipe 7, and the drain pipe 7 is connected to the inside of the separator body 1.

[0022] When the separator body 1 is in use, the steam inlet pipe 5 and the steam outlet pipe 6 are connected to the corresponding pipes through the connecting flange 12, and the steam-water mixture enters the separator body 1 through the steam inlet pipe 5. The steam-water mixture moves downward, with a part of it colliding with the inclined partition plate 8 and a part of it colliding with the spiral separation guide plate 10, thereby achieving the preliminary separation of steam and water. The water drips through the through hole 13 on the liquid separation plate 11, and the remaining steam-water mixture rises through the separation inner sleeve 4. When it contacts the auxiliary separation structure 9 at the upper head 2, it is dispersed and further separated. After separation, the water flows along the inclined partition plate 8 and finally flows from the liquid guide pipe 14 to the lower head 3. The steam is discharged from the steam outlet pipe 6, and the water at the lower head 3 is discharged through the drain pipe 7, thereby achieving an efficient steam-water separation effect.

[0023] Through the above implementation scheme, the auxiliary separation structure 9 includes a condensation guide component 901 and a centrifugal component 902. The upper end of the condensation guide component 901 passes through the upper head 2, and the condensation guide component 901 is connected to the centrifugal component 902. The centrifugal component 902 is located directly above the separation inner sleeve 4.

[0024] When in use, when the steam and water rise through the separation inner sleeve 4, they first contact the centrifugal assembly 902, part of which diffuses to the surroundings through the centrifugal assembly 902, and part of which continues to move upward to contact the condensation guide assembly 901. The diffused steam and water are directly separated, and the water drops onto the inclined partition 8, while the steam and water contacting the condensation guide assembly 901 are separated on the condensation guide assembly 901, and the water flows along the condensation guide assembly 901 and drops onto the inclined partition 8, and finally the water is discharged through the liquid guide pipe 14, and the steam is output from the steam outlet pipe 6.

[0025] The condensation guide assembly 901 includes an arc-shaped cover 9011, a cavity 9012, an inlet pipe 9013 and an outlet pipe 9014. The cavity 9012 is opened on the arc-shaped cover 9011, the inlet pipe 9013 is fixed at the edge of the arc-shaped cover 9011, and the outlet pipe 9014 is installed on the top of the arc-shaped cover 9011. The inlet pipe 9013 and the outlet pipe 9014 are connected to the cavity 9012.

[0026] The centrifugal assembly 902 includes a connecting shaft 9021, a bearing 9022, a connecting sleeve 9023, a turbine blade 9024 and a circular hole 9025. The bearing 9022 is installed at the lower end of the connecting shaft 9021, and the connecting shaft 9021 is set on the condensation guide assembly 901. The connecting sleeve 9023 is fixedly connected to the turbine blade 9024, and the connecting sleeve 9023 is sleeved on the bearing 9022 through the circular hole 9025.

[0027] During the process of steam and water contacting the centrifugal assembly 902, a force is applied to the turbine blades 9024 on the connecting sleeve 9023. The turbine blades 9024 rotate on the connecting shaft 9021 through the bearing 9022 and provide centrifugal force, so that part of the steam and water diffuses to the surroundings, and part of the steam and water passes through the turbine blades 9024 and contacts the arc cover 9011. At this time, cold water is input into the cavity 9012 through the water inlet pipe 9013, and hot water is discharged from the water outlet pipe 9014. The cold water condenses and separates the steam and water, and the water flows along the arc cover 9011 toward the edge position and finally drips onto the inclined partition 8, which can prevent water from dripping from the middle position into the separation inner sleeve 4. At the same time, the rotating turbine blades 9024 can also form a barrier to further prevent water from dripping from the middle position into the separation inner sleeve 4, and will not affect the normal rise of steam and water in the separation inner sleeve 4. The separated steam is discharged from the steam outlet pipe 6, and the water flows through the liquid guide pipe 14 and is finally discharged from the drain pipe 7 for recycling.
