Description

Technical Field

[0001] The utility model relates to the technical field of steam-water separators, in particular to an anti-scaling type steam-water separator. Background Art

[0002] Existing steam-water separators do not pre-filter the steam-water mixture to be separated, which easily causes a large amount of dirt to accumulate inside the separator, making it difficult to clean and affecting the separation efficiency of the separator. Therefore, some anti-scaling steam-water separators will set a filter at the inlet to filter the steam and water. For example, Chinese patent CN207769465U (an anti-scaling steam-water separator) sets a filter tube at the inlet and a filter inside the filter tube. However, after a period of use, the filter holes of the filter will be blocked by impurities, which will cause the steam and water to enter unsmoothly, resulting in the steam-water separator not being able to work properly.

A filter screen 508 is fixedly installed inside the filter pipe 501. The drain pipe 502 is connected to the filter pipe 501. The drain pipe 502 is located on the left side of the filter screen 508. The water inlet pipe 503 is connected to the inlet pipe 2. The water inlet pipe 503 is located on the right side of the filter pipe 501. A valve 504 is provided at the connection between the inlet pipe 2 and the left end of the filter pipe 501. The inlet pipe 2 and the separator housing 1 are connected. A valve 2 505 is provided at the connection point, a valve 4 507 is provided at the connection point between the water inlet pipe 503 and the inlet pipe 2, a valve 3 506 is provided at the connection point between the drain pipe 502 and the filter pipe 501, a guide pipe 1 509 and a guide pipe 2 5010 are fixedly installed on the inner wall of the filter pipe 501, the guide pipe 1 509 and the guide pipe 2 5010 are both located on the left side of the filter screen 508, the guide pipe 1 509 and the guide pipe 2 5010 are both trumpet-shaped, and the trumpet mouths on the guide pipe 1 509 and the guide pipe 2 5010 are opposite to each other. The connection between the drainage pipe 502 and the filter pipe 501 is located between the guide pipe 1 509 and the guide pipe 2 5010. The filter pipe 501 is provided for installing the filter screen 508, so that when the soda passes through the filter screen 508, the impurities therein are filtered out by the filter screen 508, thereby preventing the impurities from forming scale inside the separator housing 1, thereby achieving the purpose of scale prevention. After the filter screen 508 has worked for a period of time, the valve 1 504 and the valve 2 505 are closed, and the valve 3 506 and the valve 4 507 are opened to pass the purified water from the water inlet. Pipe 503 is introduced, and clean water is used to backwash the filter 508 from the right side of the filter 508 to wash away impurities blocking the filter 508. The impurities are discharged from the drain pipe 502 along with the water flow. A guide pipe 1 509 and a guide pipe 2 5010 are provided to guide the soda and backwash water. In particular, when the backwash water flows out from the guide pipe 2 5010 and then flows onto the guide pipe 1 509, the water is rebounded by the inner wall of the guide pipe 1 509, so that the water quickly enters the drain pipe 502 and is then discharged.

[0022] A hollow tube 8 is fixedly installed inside the separator shell 1, and the interior of the hollow tube 8 is connected to the air outlet pipe 3. A spiral blade 9 is fixedly installed on the outer wall of the hollow tube 8. The bottom end of the hollow tube 8 is an opening. A liquid separator 10 is fixedly installed on the inner wall of the separator shell 1. The liquid separator 10 is located between the bottom end of the hollow tube 8 and the water outlet pipe 4. The different specific gravities of liquid and gas are utilized to separate the water from the soda when it passes through the spiral blade 9. The water drops onto the liquid separator 10, and the gas rises from the bottom end of the hollow tube 8 and is then discharged from the air outlet pipe 3.

[0023] The bottom end of the drain pipe 502 and the top end of the water inlet pipe 503 are both fixedly installed with quick-release connectors for quickly connecting the drain pipe 502 to the sewage pipe, and connecting the water inlet pipe 503 to the clean water pipe.

[0024] A pressure gauge 6 is fixedly installed on the inlet pipe 2 and is located on the right side of the valve 2 505 . The pressure gauge 6 is provided to detect the pressure of the steam and water before entering the separator housing 1 .

[0025] The left side of the separator housing 1 is connected to a pressure relief pipe 7 , on which a pressure relief valve is provided. The pressure relief pipe 7 is close to the inlet pipe 2 .

A scattering plate 13 is fixedly installed on the outer wall of the rotating tube 12. The central axis of the rotating tube 12 is higher than the central axis of the inlet pipe 2. By using the scattering plate 13 that is higher than the inlet pipe 2, the soda and water can be blocked by the scattering plate 13 when passing through the scattering plate 13, and then flow downward, so that the scattering plate 13 can not only play the role of scattering the soda and water, but also play the role of diverting the flow downward.

[0027] Working principle: When in use, the soda is passed through the inlet pipe 2, and the impurities therein are filtered out after the soda passes through the filter 508, and then enters the separator shell 1 from the inlet pipe 2. The soda is blown to the scattering plate 13, and is scattered by the scattering plate 13 and guided to the spiral blade 9. The different specific gravities of liquid and gas are used to separate the water from the soda when it passes through the spiral blade 9, and the water drops onto the liquid separation plate 10. The gas rises from the bottom of the hollow tube 8 and is then discharged from the air outlet pipe 3. After the filter 508 has worked for a period of time, valve one 504 and valve two 505 are closed, and valve three 506 and valve four 507 are opened, and clean water is passed through the water inlet pipe 503. The clean water backwashes the filter 508 from the right side of the filter 508 to flush out the impurities blocking the filter 508, and the impurities are discharged from the drain pipe 502 along with the water flow.

[0028] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
