Description

Technical Field

[0001] This utility model relates to steam-water separation technology, and more particularly to a steam-water separation tank device suitable for steam systems. Background Technology

[0002] Gas-liquid separators are primarily used to separate water and gas in a medium. In the production and processing of petrochemicals, environmental protection, and new energy industries, the resulting high-temperature wastewater often contains toxic, harmful, and even flammable gases, with complex compositions. Therefore, gas-liquid separators must be used to treat the wastewater during discharge. If not treated in time, the wastewater will carry the gas into the next process, affecting production efficiency and potentially causing safety hazards. Untreated gas, if directly released into the air, will pollute the environment and harm the health of workers; while untreated high-temperature wastewater, if directly discharged into underground pipe networks, will damage the pipe network system and seep into the soil, polluting the land and groundwater.

[0003] Existing gas-liquid separators are baffle-type separators. The medium changes its flow direction multiple times within the separator. Due to the large mass and inertia of the water droplets, when they encounter a baffle that changes the flow direction, the gas can bypass the baffle and continue forward, while the water droplets accumulate on the baffle and eventually fall to the bottom of the separator for discharge. This gas-liquid separator has significant drawbacks: the container is cylindrical, and key components such as the cylinder, internal baffles, end caps, and fixed legs require special processing; the overall structure is large, occupying considerable space; the internal working status of the gas-liquid separator cannot be observed and reported in a timely and effective manner during operation; the gas-liquid separation effect relies solely on the kinetic energy of the medium without auxiliary measures, resulting in unstable gas-liquid separation and easy mixing of gas with the discharged wastewater. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by proposing a steam-water separator device suitable for steam systems. This device has a simple, reasonable, and compact structure. It meets the relevant requirements for the discharge of steam-containing wastewater within steam systems, effectively improves the steam-water separation effect, reduces the gas content in high-temperature wastewater, minimizes the impact on the surrounding environment, and eliminates safety hazards.

[0005] It should be noted that, in this utility model, unless otherwise specified, the specific meaning of "comprising" in the context of composition definition and description includes both open-ended meanings such as "comprising," "including," etc., and closed-ended meanings such as "composed of," "consisting of," etc., and similar meanings.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a steam-water separator device suitable for steam systems, comprising: a steam-water separator body, wherein a baffle is provided inside the steam-water separator body; an inlet pipe is provided on one side of the steam-water separator body, and a sight glass, an outlet pipe, and an vent pipe are provided on the side opposite to the inlet pipe; an outlet pipe control valve is installed in conjunction with the outlet pipe, and an vent pipe control valve is installed in conjunction with the vent pipe; the outlet of the outlet pipe and the outlet of the vent pipe are connected; a level gauge port and an exhaust port are provided on the top of the steam-water separator body, and a level sensor is installed in conjunction with the level gauge port.

[0007] Furthermore, the overall shape of the gas-water separator tank is square. The square structure is relatively simple to manufacture, and compared to the cylindrical structure of a general gas-water separator tank, the gas-water separator tank has a larger storage capacity and better gas condensation effect.

[0008] Furthermore, the bottom of the gas-water separator is provided with a fixed base plate, and the fixed base plate is provided with positioning bolt holes. The expansion bolts cooperate with the positioning bolt holes, so that the gas-water separator can be installed and fixed more stably on the foundation plane.

[0009] Furthermore, the baffle includes: two short plates connected to the top of the gas-water separator tank body and one long plate connected to the bottom of the gas-water separator tank body. The long plate is located between the two short plates, and the two short plates and the long plate are parallel. Both ends of the short plates and the long plate are connected to the gas-water separator tank body. The baffle is positioned perpendicular to the medium inlet direction of the inlet pipe, and the baffle serves to condense steam, divert the medium, and support the tank body's strength.

[0010] Furthermore, the lower edge of the short plate is lower than the upper edge of the long plate.

[0011] Furthermore, the two short plates are respectively close to the inlet pipe and the outlet pipe, with the lower edge of the short plate close to the outlet pipe being higher than the outlet pipe.

[0012] The baffle structure inside the gas-liquid separator separates the gas and liquid inside the tank. There are three baffles in total: a short baffle connected to the top near the inlet pipe, a long plate with a broken top and bottom in the middle of the gas-liquid separator, and a short baffle connected to the top near the outlet pipe. The bottom of the short baffle is installed at a height higher than the outlet pipe elevation.

[0013] Furthermore, the installation height of the sight glass is located between the lower edge of the short board and the outlet pipe nozzle, that is, the installation height of the sight glass corresponds to the bottom height of the baffle-connected top short board and the installation height of the outlet pipe nozzle at the same time. The arrangement of the sight glass can directly observe the liquid level in the steam-water separation tank. The sight glass adopts the structure of a short-tube sight glass, with a sealed structure and a transparent tempered borosilicate glass embedded in the middle. This material is heat-resistant and corrosion-resistant, meeting the working conditions of the steam-water separation tank device and being easy to observe the liquid level inside the device.

[0014] Furthermore, an inner extension steel pipe communicating with the outlet pipe nozzle is arranged inside the steam-water separation tank. The nozzle of the inner extension steel pipe is perpendicular to the fixed bottom plate and has a certain height reserved from the fixed bottom plate. This structure can effectively reduce the gas content in the discharged sewage. An outlet pipe nozzle control valve is installed in a supporting manner at the outlet pipe nozzle. The pipeline behind the outlet pipe nozzle control valve and the pipeline behind the vent pipe nozzle control valve converge through a three-way element. The residual sewage in the steam-water separation tank can flow out through the vent pipe nozzle. A discharge pipe nozzle control valve is provided at the discharge pipe nozzle. When a failure or other situations occur in the steam-water separation tank device, opening the discharge pipe nozzle control valve can discharge the residual sewage in the tank. The pipeline behind the vent pipe nozzle control valve and the pipeline behind the outlet pipe nozzle control valve converge through a three-way element.

[0015] Furthermore, the exhaust pipe nozzle is located at the top of the steam-water separation tank and away from the inlet pipe nozzle side. The gas in the steam-water separation tank is discharged through the exhaust pipe nozzle; the liquid level gauge nozzle is also arranged at the top of the steam-water separation tank for installing a liquid level sensor.

[0016] Furthermore, the liquid level sensor supporting the liquid level gauge nozzle is communicatively connected to the outlet pipe nozzle control valve through a control unit. The liquid level sensor and the outlet pipe nozzle control valve interlock to control the steam-water separation tank device. When the liquid level sensor detects that the liquid level rises to the set height, the outlet pipe nozzle control valve opens, and the sewage in the steam-water separation tank flows out. When the liquid level drops to the set height, the outlet pipe nozzle control valve closes.

[0017] Furthermore, the exhaust pipe nozzle is connected to a negative pressure gas collection system, and the negative pressure system functions to guide the gas flow direction in the steam-water separation tank.

[0018] The working principle of this utility model's steam-water separator device for steam systems is as follows: The gas-liquid mixture enters the steam-water separator through the inlet pipe. Internal baffles within the separator divert and guide the medium. Some steam condenses upon contact with the baffles or the low-temperature air inside the tank, producing condensate, which mixes with the wastewater within the tank. Residual steam flows through the internal channels of the steam-water separator to the exhaust pipe, the rear end of which is connected to a negative pressure gas collection system. After the gas-water separator has been running for a period of time, when the sewage level inside the tank rises to the specified parameter of the level sensor installed at the level gauge port, the system interlock is activated, the outlet control valve opens, and the sewage flows out through the outlet to the external sewage treatment system. When the sewage level inside the tank drops to the specified parameter of the level sensor installed at the level gauge port, the system interlock is deactivated, the outlet control valve closes, and the sewage no longer flows out through the outlet. This interlocking method effectively utilizes the siphon structure of the internal extension pipe, effectively avoiding the situation where some gas is mixed with the sewage and discharged together, as is common in ordinary gas-water separators. When an abnormal liquid state is observed inside the gas-water separator through the sight glass, the drain port control valve can be opened to drain the sewage from the tank. After this, the level sensor at the level gauge port and the outlet control valve at the outlet can be inspected and repaired. Compared to ordinary gas-water separators, this design makes it easier to observe the internal working status.

[0019] This utility model is applicable to a steam-water separator device for steam systems, and has the following advantages compared with the prior art:

[0020] 1) This utility model is applicable to the steam-water separator device for steam systems. By increasing the length of the flow channel in the tank, the steam-water separation effect is significantly improved. Through the negative pressure guidance of the internal baffle and exhaust pipe of the steam-water separator, the water in the steam is forced to come into contact with the cold air and wall plate inside the steam-water separation tank, thereby achieving efficient condensation and separation.

[0021] 2) This utility model is applicable to a steam-water separator device for steam systems. Through the construction of an internally extended steel pipe at the outlet, the gas content in the discharged wastewater is effectively reduced. Simultaneously, the interlocking action between the liquid level sensor and the outlet control valve enables automatic wastewater discharge, further enhancing the automation level of the device.

[0022] 3) This utility model is applicable to the steam-water separator device for steam systems. It adopts a fixed base plate and sight glass, which significantly simplifies the installation and maintenance process of the equipment and improves the ease of operation compared with traditional steam-water separators.

[0023] In summary, the steam-water separator device of this utility model is simple and practical in structure, easy to install and maintain, and can effectively improve the steam-water separation effect and reduce the gas content in high-temperature wastewater. Attached Figure Description

[0031] Example 1

Figure 1-3 As shown, a steam-water separator device suitable for steam systems includes: a steam-water separator tank body 1, with a baffle 2 inside the tank body 1; an inlet pipe 3 on one side of the tank body 1, and a sight glass 4, an outlet pipe 5, and an vent pipe 6 on the side opposite to the inlet pipe 3; an outlet pipe 5 is equipped with an outlet pipe control valve 11, and an vent pipe 6 is equipped with an vent pipe control valve 12; the outlet of the outlet pipe 5 and the outlet of the vent pipe 6 are connected; a level gauge port 7 and an exhaust port 8 are provided on the top of the steam-water separator tank body 1, and a level sensor 9 is equipped with the level gauge port 7.

[0033] The gas-water separator tank body 1 has a square shape. The square structure is relatively simple to manufacture. Compared with the cylindrical structure of general gas-water separators, the gas-water separator tank body 1 has a larger storage capacity and a better gas condensation effect.

[0034] The bottom of the gas-water separator tank body 1 is provided with a fixed base plate 10. The fixed base plate 10 is provided with positioning bolt holes. The expansion bolts cooperate with the positioning bolt holes, so that the gas-water separator device can be installed and fixed more stably on the foundation plane.

[0035] The baffle 2 includes two short plates connected to the top of the gas-water separator tank body 1 and one long plate connected to the bottom of the gas-water separator tank body 1. The long plate is located between the two short plates, and the two short plates and the long plate are parallel. Both ends of the short plates and the long plate are connected to the gas-water separator tank body 1. The baffle is positioned perpendicular to the medium inlet direction of the inlet pipe, and serves to condense steam, divert the medium, and support the tank body's strength. The lower edge of the short plate is lower than the upper edge of the long plate. The two short plates are respectively adjacent to the inlet pipe 3 and the outlet pipe 5, with the lower edge of the short plate adjacent to the outlet pipe 5 being higher than the outlet pipe 5.

[0036] The baffle 2 inside the tank body 1 of the gas-water separator separates the gas and liquid inside the tank. There are three baffles 2 in total. Near the inlet pipe 3, there is a short plate connected to the top. The tank body 1 of the gas-water separator has a long plate with a broken top and bottom in the middle. Near the outlet pipe 5, there is a short plate connected to the top. The bottom of the short plate connected to the top is installed at a height higher than the elevation of the outlet pipe 5.

[0037] The sight glass 4 is installed at a height between the lower edge of the short plate and the outlet pipe 5, meaning its installation height corresponds to both the bottom height of the short plate connected to the baffle 2 and the installation height of the outlet pipe 5. The sight glass 4 allows direct observation of the liquid level inside the gas-water separator tank 1. The sight glass adopts a short-tube structure, is sealed, and has a transparent tempered borosilicate glass inlaid in the middle. This material is high-temperature resistant and corrosion-resistant, meeting the operating conditions of the gas-water separator and facilitating observation of the internal liquid level.

[0038] The gas-water separator tank body 1 is equipped with an internally extending steel pipe connected to the outlet port 5. The outlet of the internally extending steel pipe is perpendicular to the fixed base plate 10 and is pre-installed at a certain height with the fixed base plate 10. This structure can effectively reduce the gas content in the discharged wastewater. The outlet port 5 is equipped with an outlet port control valve 11. The rear end pipe of the outlet port control valve 11 and the rear end pipe of the venting port control valve 12 are connected by a three-way component. The residual wastewater in the gas-water separator tank can flow out through the venting port. The venting port is equipped with a venting port control valve. When the gas-water separator device malfunctions or other situations occur, opening the venting port control valve can discharge the residual wastewater in the tank. The rear end pipe of the venting port control valve and the rear end pipe of the outlet port control valve are connected by a three-way component.

[0039] The exhaust pipe is located at the top of the gas-water separator and away from the inlet pipe. Gas inside the gas-water separator is discharged through the exhaust pipe. The level gauge port is also located at the top of the gas-water separator and is used to install the level sensor.

[0040] The level sensor 9, which is matched with the level gauge port 7, is connected to the outlet control valve 11 via a control unit. The level sensor 9 and the outlet control valve 11 interlock to control the gas-water separator device. When the level sensor 9 detects that the liquid level has risen to a set height, the outlet control valve 11 opens, and the sewage in the gas-water separator 1 flows out. When the liquid level falls to a set height, the outlet control valve 11 closes.

[0041] The exhaust port 8 is connected to the negative pressure gas collection system, which guides the gas flow inside the steam-water separator 1.

[0042] The working principle of this utility model's steam-water separator device for steam systems is as follows: The gas-liquid mixture enters the steam-water separator body 1 through the inlet pipe 3. The baffle 2 inside the steam-water separator body 1 diverts and guides the medium. Some of the steam condenses due to contact with the baffle 2 or the low-temperature air inside the tank, producing condensate, which mixes with the wastewater inside the tank. The remaining steam flows through the internal channel of the steam-water separator body 1 to the exhaust pipe 8, the rear end of which is connected to a negative pressure gas collection system. After the gas-water separator has been running for a period of time, when the sewage level inside the tank rises to the specified parameter of the level sensor 9 installed at the level gauge port 7, the system interlock is activated, the outlet control valve 11 opens, and the sewage flows out through the outlet port 5 to the external sewage treatment system. When the sewage level inside the tank drops to the specified parameter of the level sensor 9 installed at the level gauge port 7, the system interlock is deactivated, the outlet control valve 11 closes, and the sewage no longer flows out through the outlet port 5. This interlocking method effectively utilizes the siphon structure of the internal extension pipe, effectively avoiding the situation where some gas is mixed with sewage and discharged together, as is seen in ordinary gas-water separators. When the abnormal liquid state is observed inside the gas-water separator tank 1 through the sight glass 4, the outlet control valve 12 of the drain port 6 can be opened to drain the sewage from the tank. After that, the level sensor 9 at the level gauge port 7 and the outlet control valve 11 at the outlet port 5 can be inspected and repaired. Compared with ordinary gas-water separators, this design makes it easier to observe the internal working status.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
