Abstract
Description
Technical Field
[0001] The present invention relates to a rotary venturi carbon neutral steam trap. Specifically, the present invention aims to improve power generation efficiency and heat recovery efficiency by separating and discharging condensed water generated in high-temperature and high-pressure steam pipelines. The present invention also has the function of efficiently cleaning steam, and can dynamically adjust the steam aperture according to the steam pressure and discharge volume, so as to achieve accurate and continuous discharge of condensed water. In this process, the present invention can stabilize the steam pressure and maintain a constant temperature. The steam trap of this design is a rotary structure with carbon neutral performance. Background Art
[0002] Typically, in industrial facilities such as power plants, steam traps are installed on the pipes of the steam delivery system. This device is mainly used to discharge condensed water generated during the constant pressure steam supply process due to external low temperature influences.
[0003] The steam trap installed on the steam pipe is essentially an intelligent automatic control valve. Its core function is to effectively separate and discharge condensed water during steam transportation while preventing steam leakage.
[0004] Therefore, the steam trap on the steam pipeline must have the function of removing air and non-condensable gases to ensure the stable performance of the entire system and achieve energy-saving effects.
[0005] If steam leaks from the steam trap in the steam pipeline, the heat carried by the steam will be lost, resulting in energy waste. At the same time, the pressure in the condensate recovery pipe will increase, which will affect the pressure balance of other steam traps in the connected pipeline, and ultimately reduce the efficiency of the entire system.
[0006] In addition, if the steam trap fails to operate properly, it may cause water hammer, which will not only damage the piping system, but also greatly shorten the service life of the valve and main pipeline.
[0007] At present, steam traps are mainly used to automatically discharge condensate from pipelines. Common designs include float type, disc type, bimetallic type, float barrel type and orifice plate type.
[0008] Among the various types of steam traps mentioned above, the float type steam trap uses the density difference between steam and condensate to discharge condensate. Although it is not susceptible to drastic fluctuations in pressure and flow, it is susceptible to damage caused by scale deposition.
[0009] The working principle of the disc type steam trap is that when condensate accumulates in the trap, the temperature inside the valve decreases, causing the pressure in the transformer chamber to drop, thereby causing the disc to rise and discharge the condensate.
[0010] The bimetallic steam trap is such that when condensate accumulates in the trap, the temperature inside the trap decreases, and the ball valve is opened through the deformation of the bimetal, thereby discharging the condensate.
[0011] The bimetal in the bimetallic steam trap is composed of two metals with different coefficients of thermal expansion bonded together and will bend due to temperature changes.
[0012] The bucket steam trap operates on the principle of buoyancy. Under normal conditions, the bucket floats and closes the drain valve; when the inlet condensate flows in and accumulates in the bucket, the bucket sinks and drives the drain valve connected to it to open, and the accumulated condensate is discharged under the action of steam pressure.
[0013] The principle of the orifice plate steam trap is to prevent steam leakage by keeping the discharged condensate occupy the small holes of the orifice plate.
[0014] Due to the advantages of minimizing steam leakage, no need for operating devices, small heat dissipation area, high heat transfer efficiency to the heating body, etc., the orifice plate steam trap has become an economical, efficient and most widely used type.
[0015] However, the orifice plate steam trap of the traditional technology will always be in the open state under the action of the pressure difference between steam and condensate, and may be frequently opened under unnecessary circumstances, resulting in valve wear, thereby shortening the service life of the steam trap and generating noise.
[0016] When the condensate in the system accumulates rapidly at a rate exceeding the expected rate, backflow to the main pipeline may occur, triggering a water hammer phenomenon, which will seriously affect the service life of the valve and the main pipeline.
[0017] Patent Document 1 (Republic of Korea Registered Patent Gazette No. 10-2181147, registered on November 16, 2020) discloses a steam trap having a Venturi nozzle type, an orifice plate nozzle type or a tunnel structure resistance pipe, and adopts a rotary adjustment mechanism to change the height difference between the drain port of the low drainage part of the steam trap and the external discharge port of the system, thereby realizing adjustable condensate discharge.
[0018] Although the nozzle type steam trap of Patent Document 1 can adjust the condensate discharge amount without replacing core components such as the orifice plate nozzle, Venturi nozzle and tunnel structure resistance pipe when the steam usage amount or working pressure changes, it cannot automatically adjust the steam flow according to the ambient temperature change, and cannot control the size of the steam hole in a way that does not require disassembly and tool intervention during the adjustment process, resulting in problems that the steam pressure and temperature fluctuate due to external temperature changes.
[0019] Patent Document 2 (Korean Registered Patent Gazette No. 10-2681773, registered on July 1, 2024) proposed an improved rotary venturi carbon-neutral steam trap, including: a valve body assembly installed between the steam supply pipe and the discharge pipe, which integrates a steam drainage device and a control valve; an intelligent adjustment system provided on the valve body, which can adjust in real time according to the steam pressure and discharge volume to ensure the stability of the system pressure and temperature; and a discharge device dedicated to draining the condensate water in the valve body. This design regulates the steam discharge volume through the precision nozzle of the drainage part, realizing the continuous and stable discharge of condensate water, while ensuring the constancy of the system temperature and pressure.
[0020] The plug-type venturi carbon-neutral steam trap related to Patent Document 2 is an invention previously applied by the applicant, which has the effect of adjusting the condensate water discharge volume according to the on-site environment, that is, this invention can control the steam pressure and the condensate water discharge volume outside the steam trap with condensate water in the venturi hole by using tools.
[0021] However, the steam drainage part of the plug-type venturi carbon-neutral steam trap related to Patent Document 2 is composed of multiple fittings including a nozzle, a rotary handle, a combination body, and a rotary cover. Therefore, there are problems that the production of the fittings of the steam drainage part is cumbersome and the production cost is relatively high. Summary of the Invention

[0070] The rotary Venturi carbon-neutral steam trap related to the present invention includes a main body (100), a steam trap part (200), and a valve part (300). Its effect is that when installing or repairing a rotary Venturi orifice steam trap that can adjust the amount of condensed water from the outside, it eliminates the restrictions on the operation or installation space, effectively improves the flow efficiency of the fluid, and effectively cleans the steam. It adjusts the size of the steam orifice according to the steam pressure and discharge amount to prevent changes in steam pressure and temperature, effectively responds to changes in condensed water, and adjusts the steam orifice from the outside according to the steam pressure, thereby adjusting the steam supply amount according to the steam pressure and discharge amount.
[0071] The main body (100) is a component installed on the steam pipeline, and its overall shape has an integrally formed inclined pipe body in the lower center of the horizontal pipe body, and a connection part (110) for installing the steam trap component (220) is provided in the center of the front end of the horizontal pipe body.
[0072] The structure of the main body (100) is such that steam flows in from one side of the horizontal pipe body and discharges from the other side.
[0073] On the connection part (110) protruding from the center of the front end of the main body (100), a rotary cover (250) of the steam trap part (200) described later is installed by threaded connection.
[0074] A protruding surface (111) is formed at the front end of the connection part (110) for installing the rear end of the nozzle (220) of the steam trap part (200).
[0075] On the protruding surface (111), a main body steam hole (112) is provided for supplying high-pressure steam flowing into the main body (100), and a condensed water discharge hole (113) is provided for discharging the condensed water processed by the steam trap part (200).
[0076] A connection part gasket (114) is installed on the connection part (110) to improve the sealing performance during the threaded connection of the rotary cover (250) and prevent the separation of the connection part (110) and the rotary cover (250).
[0077] The steam trap unit (200) is installed on the connection part (110) of the main body (100), and its function is to adjust the steam pressure according to the steam pressure and discharge amount, so as to keep the steam pressure and temperature constant, thus facilitating steam supply.
[0078] The steam trap unit (200) includes a nozzle (220), a rotary cover (250), a nameplate (260) and a cover ring (270).
[0079] In the rotary vane Venturi carbon neutral steam trap involved in the present invention, the condensed water generated by the initially introduced steam remains inside the rotary cover (250), and when the newly generated condensed water exceeds a predetermined water level, it is discharged through the condensed water drain hole (113) of the connection part (110).
[0080] The nozzle (220) is a part that adjusts the amount of steam discharged to the main steam hole (112) of the connection part (110) of the main body (100), and can rotate left and right in front of the connection part (110) of the main body (100).
[0081] The shape of the nozzle (220) is that a pressing circular plate (222) is provided in front of the adjusting circular plate (221) closely attached to the protruding surface (111) of the connection part (110), and an adjusting shaft (223) is provided in front of the pressing circular plate (222), which is inserted and connected to the coupling hole (251) of the rotary cover (250) to be mentioned later.
[0082] At the position corresponding to the main steam hole (112) on the adjusting circular plate (221) of the nozzle (220), a plurality of nozzle steam holes (221-1) are formed in a circular arrangement to adjust the steam supply amount flowing into the main steam hole (112) of the protruding surface (111) of the connection part (110).
[0083] The plurality of nozzle steam holes (221-1) formed on the adjusting circular plate (221) are arranged in the order of increasing diameter in the clockwise or counterclockwise direction.
[0084] In the illustrated embodiment, there are 5 nozzle steam holes (221-1) on the adjusting circular plate (221). Of course, in the rotary vane Venturi carbon neutral steam trap involved in the present invention, the number of nozzle steam holes (221-1) formed on the adjusting circular plate (221) can be a predictable number, such as 1 to 4 or 6 to 8, etc.
[0085] The pressing circular plate (222) is a part that, during the process of screwing the rotary cover (250) into the connecting part (110), moves the nozzle (220) towards the connecting part (110), so that the adjusting circular plate (221) of the nozzle (220) stably adheres to the protruding surface (111) of the connecting part (110). Its diameter is slightly smaller than that of the adjusting circular plate (221).
[0086] The adjusting shaft (223) is a component used to connect a wrench to achieve the left - right rotation of the nozzle (220). On the exposed end face passing through the coupling hole (251) of the rotary cover (250), there are a wrench groove (223 - 1) and an indicating groove (223 - 2).
[0087] An elastic compression washer (224) is inserted and installed on the adjusting shaft (223). When the rotary cover (250) is thread - connected to the connecting part (110), this washer applies appropriate elastic pressure to the pressing circular plate (222) to ensure the stability and sealing of the assembly.
[0088] The compression washer (224) adopts a disc - shaped design with the central part protruding forward to provide elastic force.
[0089] In the figure, the reference numeral 225 not shown is an O - ring for sealing.
[0090] The rotary cover (250) is installed in front of the connecting part (110) of the main body (100) and is used to tightly support the nozzle (220). It is thread - connected to the connecting part (110) of the main body (100).
[0091] The rotary cover (250) is a cylindrical shape with a sealed front end. At the front end, there is a coupling hole (251) for inserting the adjusting shaft (223) of the nozzle (220), and at the outer peripheral end, there is an external thread for thread - connecting with the cover ring (270).
[0092] The nameplate (260) is used to display the steam volume corresponding to the steam volume adjustment position of the nozzle (220). It is in the shape of a circular plate, and in the center, there is a through - hole (261) for the end part of the adjusting shaft (223) of the nozzle (220) to pass through.
[0093] On the said nameplate (260), there is formed a steam volume component (262) for adjusting the steam volume supplied by the main body (100), and a steam hole component (263) formed on the adjusting circular plate (221) to confirm the position of the nozzle steam hole (221 - 1).
[0094] The cover ring (270) is a part that fixedly installs the nameplate (260) in front of the rotary cover (250). It is located at the front end of the rotary cover (250).
[0095] The cover ring (270) is annular to identify the steam quantity member (262) and the steam hole member (263) formed on the nameplate (260) and is screwed onto the rotary cover (250).
[0096] In the rotary venturi carbon neutral steam trap according to the present invention, the steam flowing into the horizontal pipe body side of the main body (100) passes through the main body steam hole (112) of the connecting portion (110) and flows into the inside of the rotary cover (250). At this time, by using a tool such as a wrench to rotate the nozzle (220) clockwise or counterclockwise, the amount of steam flowing into the inside of the rotary cover (250) can be adjusted.
[0097] Specifically, the user can insert a tool into the wrench groove (223-1) at the front end of the adjusting shaft (223) of the nozzle (220) exposed from the coupling hole (251) of the rotary cover (250), and at the same time refer to the steam quantity diagram (262) and the steam hole diagram (263) on the nameplate (260), and rotate the nozzle (220) clockwise or counterclockwise, so as to conveniently adjust the amount of steam entering the inside of the rotary cover (250).
[0098] When the nozzle (220) is rotated clockwise or counterclockwise by using a tool, the nozzle steam hole (221-1) on the adjusting circular plate (221) corresponding to the main body steam hole (112) of the connecting portion (110) can be changed. If the nozzle steam hole (221-1) with a diameter smaller than the original set nozzle steam hole (221-1) corresponds to the main body steam hole (112) of the connecting portion (110), the amount of steam flowing into the inside of the rotary cover (250) is reduced; if the nozzle steam hole (221-1) with a diameter larger than the original set nozzle steam hole (221-1) corresponds to the main body steam hole (112) of the connecting portion (110), the amount of steam flowing into the inside of the rotary cover (250) is increased.
[0099] The condensed water generated by the steam flowing into the inside of the rotary cover (250) through the nozzle steam hole (221-1) of the adjusting circular plate (221) is discharged through the condensed water discharge hole (113) of the connecting portion (110) and is supplied to the valve portion (300) through the main body (100).
[0100] As described above, in the rotary venturi carbon neutral steam trap according to the present invention, the user can adjust the amount of steam flowing into the rotary cover (250) according to the on-site situation, so as to discharge an appropriate amount of condensed water to maintain a certain temperature.

[0102] The valve part (300) is a part that can discharge the condensed water condensed in the main body (100). It is arranged in the inclined pipe body of the main body (100) to discharge the condensed water generated by adjusting the steam supply amount from the steam trap part (200).
[0103] The valve part (300) is composed of a screen cover (310), a plug (320) and a foreign object removal component (330).
[0104] The screen cover (310) is inserted into the inclined pipe body, that is, the inside of the cap connecting pipe (120) of the main body (100), and is spirally connected thereto.
[0105] A threaded fastening hole (311) is formed in the center of the screen cover (310), and the plug (320) is connected in the fastening hole.
[0106] The inside of the screen cover (310) has a coupling groove (312-1) capable of coupling the foreign object removal component (330), and a mesh coupling body (312) is formed. A plurality of foreign object removal holes (312-2) are formed in the coupling groove (312-1) of the mesh coupling body (312) to remove the foreign objects contained in the steam filtered by the foreign object removal component (310) by using high-pressure steam.
[0107] The foreign object removal holes (312-2) are preferably formed as circular or oval long holes, but can also be formed into various other shapes.
[0108] A cover gasket (313) made of metal is provided in the screen cover (310), and the cover gasket (313) has its own elasticity to prevent the cap connecting pipe (120) and the screen cover (310) from separating in the coupled state.
[0109] In addition, the cover gasket (313) maintains the sealing performance between the cap connecting pipe (120) and the screen cover (310) through its own elasticity, thereby preventing steam leakage.
[0110] The plug (320) is arranged in the fastening hole (311) to discharge the foreign objects filtered by the foreign object removal component (330) controlled by the on-off valve, and at the same time discharge the condensed water generated by the steam flowing in from the main body (100).
[0111] In addition, in order to remove impurities in the steam flowing in from the main body (100), an impurity removal component (330) is installed on the grid body (312) of the filter cap (320) and is located inside the cap connecting pipe (120).
[0112] The impurity removal component (330) is composed of a first filter screen (331), a second filter screen (332), and a grid fixing body (333).
[0113] The first filter screen (331) is installed inside the connecting groove (312-1) formed on the grid body (312) of the filter cap (310) and is located inside the cap connecting pipe (120).
[0114] The second filter screen (332) is kept at a certain distance from the first filter screen (331) and is also installed inside the connecting groove (312-1) formed on the grid body (312) and is located inside the cap connecting pipe (120).
[0115] The mesh holes of the first filter screen (331) are larger than those of the second filter screen (332), and the mesh holes of the second filter screen (332) are relatively small. This design enables impurities to be removed step by step through the first filter screen (331) and the second filter screen (332).
[0116] The first filter screen (331) and the second filter screen (332) ensure that the steam flowing towards the steam trap part (200) has been filtered for impurities.
[0117] The grid fixing body (333) has a circular structure. One side is provided with a grid fixing protrusion (333-1), and a grid fixing groove (333-2) is provided inside the protrusion. The first filter screen (331) is installed on the inner side surface of the grid fixing protrusion (333-1), and the second filter screen (332) is installed in the grid fixing groove (333-2).
[0118] The grid fixing body (333) is inserted into the inside of the cap connecting pipe (120) in a state where the first filter screen (331) and the second filter screen (332) are provided. This facilitates the installation of the first filter screen (331) and the second filter screen (332), and also facilitates the assembly of the steam trap part (200), thereby improving the convenience of production.
[0119] The rotary venturi carbon neutral steam trap involved in the present invention can set the steam pressure and the condensate discharge amount from the outside, so the condensate discharge amount can be easily adjusted according to the on-site environment.
[0120] In addition, while effectively cleaning the steam, the position of the nozzle steam hole (221-1) can be adjusted according to the steam pressure and discharge amount, so that without changing the steam pressure and temperature, the change of condensate water can also be dealt with, thereby improving the efficiency of steam supply.
[0121] In addition, the diameter of the nozzle steam hole (221-1) gradually increases from the outside of the rotary venturi orifice steam trap that can adjust the amount of condensate water using steam pressure, thus ensuring the rapid discharge of condensate water.
[0122] The rotary venturi carbon-neutral steam trap of the present invention discharges condensate water by using a valve portion (300) that can adjust the amount of condensate water from the outside. Therefore, even if a large amount of condensate water is generated below a specific temperature, the smooth discharge of condensate water can be ensured.
[0123] The invention completed by the inventor has been specifically described according to the above embodiments, but the present invention is not limited to the above embodiments, and various changes can be made without departing from its gist.
