[0035] See also Figure 1 and Figure 2 As shown, a pure steam sampling device provided in one embodiment of the present application can be used for online sampling of condensate from a pure steam generator, and can also be used for offline sampling of condensate on a pure steam sampling vehicle. The application environment of the pure steam sampling device is not limited herein.

[0036] The pure steam sampling device has an independent non-condensable gas separation chamber. Specifically, the pure steam sampling device includes a tank body 1, a heat exchange component 2 and a diffusion tube 3. A baffle 11 is provided in the tank body 1, and the tank body 1 is divided into a condensation chamber 12 and a separation chamber 13 arranged in an upper and lower manner by the baffle 11. The condensation chamber 12 is located above the baffle 11, and the separation chamber 13 is located below the baffle 11. The condensation chamber 12 has a steam inlet 121, and the heat exchange component 2 is arranged in the condensation chamber 12. After the pure steam enters the condensation chamber 12 from the steam inlet 121, based on the heat exchange effect of the heat exchange component 2 in the condensation chamber 12, the pure steam can be cooled and condensed. In this way, the heat exchange component 2 condenses the condensable steam in the condensation chamber 12 into condensed water, while the non-condensable gas in the condensation chamber 12 remains as non-condensable gas, so that condensed water mixed with non-condensable gas will be formed in the condensation chamber 12.

[0037] The baffle wall 11 is provided with a steam discharge port 112 that runs through the middle to the side wall, and the steam discharge port 112 is connected to the condensation chamber 12. In this way, the uncondensed steam and non-condensable gas in the condensation chamber 12 after heat exchange by the heat exchange component 2 are discharged through the steam discharge port 112. It can be understood that the extension direction of the steam discharge port 112 is perpendicular to the thickness direction of the baffle wall 11, so that the steam discharge port 112 runs through the side wall of the baffle wall 11.

[0038] The heat exchange structure of the heat exchange component 2 has various types and is not limited to Figure 1 The heat exchange structure of the spiral tube heat exchanger 21 is shown. In some embodiments, the heat exchange component 2 may also be a double tube sheet heat exchanger or a shell and tube heat exchanger or other types of heat exchangers that can condense the pure steam entering the condensation chamber 12 through heat exchange. The type of the heat exchange component 2 is not limited here.

[0039] In this embodiment, one end of the diffusion tube 3 is connected to the baffle 11 and communicated with the condensation chamber 12. After the condensed water mixed with non-condensable gas formed in the condensation chamber 12 enters the diffusion tube 3, the diffusion tube 3 is used to perform instantaneous flash evaporation on the condensed water to separate the non-condensable gas from the condensed water, thereby achieving separation of the non-condensable gas. Therefore, the pure steam sampling device can achieve a good gas-liquid separation effect, so as to improve the accuracy of the sampling result when sampling the condensed water.

[0040] The retaining wall 11 can be integrally formed with the tank body 1, so that no other assembly structure is required to improve the efficiency of separating the tank body 1 into the condensation chamber 12 and the separation chamber 13. It can be understood that since the tank body 1 is provided with the separation chamber 13 independent of the condensation chamber 12, the separation chamber 13 can be used to collect the separated non-condensable gas, so as to ensure the gas-liquid separation effect.

[0041] For example, in some embodiments, a vent hole 33 is provided on the wall of the diffuser 3, and the vent hole 33 is connected to the separation chamber 13. Therefore, when the condensed water in the diffuser 3 is flash evaporated to separate the non-condensable gas, the non-condensable gas can enter the separation chamber 13 through the vent hole 33, thereby realizing the timely separation of the non-condensable gas and the condensed water, avoiding the re-mixing of the non-condensable gas with the condensed water, so as to ensure the purity of the condensed water, thereby facilitating the improvement of the accuracy of sampling and testing the condensed water.

[0042] Continue reading Figure 1 and Figure 2 As shown, the baffle 11 is provided with a through hole 111 that runs through the thickness direction thereof. It is understandable that when no other structural components are provided in the through hole 111, the condensation chamber 12 located above the baffle 11 and the separation chamber 13 located below the baffle 11 are connected through the through hole 111. Therefore, the through hole 111 can be considered as the condensate outlet of the condensation chamber 12, so that when the steam generates condensate through the action of the heat exchange component 2, the condensate in the condensation chamber 12 will pass through the through hole 111 and enter the separation chamber 13 below for separation. In the pure steam sampling device of the present application, the diffuser 3 serves as a structural component for separating the non-condensable gas in the condensate at the separation chamber 13, and one end of the diffuser 3 cooperates with the through hole 111, so that the condensate formed in the condensation chamber 12 can enter the diffuser 3 through the through hole 111.

[0043] The pure steam sampling device also includes a throttling orifice plate 4, which is arranged in the path of the condensed water entering the diffusion tube 3. In this way, the condensed water in the condensation chamber 12 will flow through the throttling orifice plate 4, so that the throttling hole 41 of the throttling orifice plate 4 is used to adjust the flow rate of the condensed water entering the diffusion tube 3, so as to facilitate the stability of the flash separation of the non-condensable gas in the condensed water by the diffusion tube 3. In this embodiment, the throttling orifice plate 4 is located above the exhaust hole 33. In other words, the exhaust hole 33 is located below the throttling orifice plate 4. Therefore, the condensed water throttled by the throttling orifice plate 4 will not be discharged from the exhaust hole 33. Accordingly, after the condensed water flows into the diffusion tube 3 through the throttling orifice plate 4, the non-condensable gas will be separated under the flash evaporation action of the diffusion tube 3.

[0044] Since the condensed water will continue to flow into the diffuser 3 from the throttle hole 41 of the throttle hole plate 4, the condensed water will hinder the non-condensable gas from passing through the throttle hole 41 upwards in the process of flowing downwards from the throttle hole 41, that is, the non-condensable gas cannot flow back through the throttle hole 41 and enter the condensation chamber 12. Therefore, the non-condensable gas can only be discharged from the exhaust hole 33 located below the throttle hole plate 4 to the separation chamber 13. It can be seen that in this embodiment, the throttle hole plate 4 is arranged in the upper path of the exhaust hole 33 of the diffuser 3, which can prevent the condensed water from entering the separation chamber 13 from the exhaust hole 33, and can also prevent the non-condensable gas separated by flash evaporation of the diffuser 3 from flowing back to the condensation chamber 12 from the throttle hole 41 of the throttle hole plate 4, so that the non-condensable gas can only enter the separation chamber 13 through the exhaust hole 33, and the condensed water can only flow downwards along the diffuser 3 through the throttle hole 41, thereby improving the gas-liquid separation effect, so as to improve the accuracy of the sampling and detection results of the condensed water.

[0045] In some embodiments, the diffuser 3 includes an inlet section 31 and an extension section 32 that are connected. The inlet section 31 is inserted into the through hole 111, so that the inlet section 31 is connected to the condensation chamber 12. The extension section 32 is connected to the bottom of the inlet section 31, so that the condensed water formed in the condensation chamber 12 will flow into the extension section 32 through the inlet section 31. In this embodiment, the inlet section 31 can serve as a condensed water outlet of the condensation chamber 12 for the condensation chamber 12, and the inlet section 31 can serve as a condensed water inlet of the diffuser 3 for the diffuser 3. The inlet section 31 and the extension section 32 can be integrally formed or plug-in. The connection method between the inlet section 31 and the extension section 32 is not limited here.

[0046] In an embodiment where the diffuser 3 includes an inlet section 31 and an extension section 32 that are connected to each other, the throttling orifice plate 4 can be connected between the inlet section 31 and the extension section 32. In other words, the inlet section 31 is connected to the top of the throttling orifice plate 4, and the extension section 32 is connected to the bottom of the throttling orifice plate 4. The inlet section 31 and the extension section 32 are connected to each other via a throttling hole 41 on the throttling orifice plate 4.

[0047] The diameter of the extension section 32 of the diffuser tube 3 is larger than the diameter of the introduction section 31 , which is more conducive to the condensed water entering the diffuser tube 3 to release non-condensable gas through flash evaporation.

[0048] Continue reading Figure 1 As shown, the pure steam sampling device further includes a liquid storage chamber 5 located below the separation chamber 13, and the liquid storage chamber 5 is used to store the condensed water flowing out of the diffusion tube 3. In this embodiment, one end of the diffusion tube 3 away from the baffle 11 extends below the liquid surface of the liquid storage chamber 5, so that the condensed water in the liquid storage chamber 5 will generate back pressure on the diffusion tube 3, so that the non-condensable gas in the condensed water after flash evaporation in the diffusion tube 3 is more easily separated under the action of the back pressure and discharged from the exhaust hole 33 to the separation chamber 13 in time.

[0049] In addition, this structural setting can also effectively reduce the interference of the temperature fluctuation of the condensed water on the conductivity. When the temperature of the condensed water increases, the flash evaporation efficiency is accelerated. At this time, the steam in the condensation chamber 12 that has not yet condensed will enter the diffusion tube 3. Since the diffusion tube 3 extends below the liquid surface of the liquid storage chamber 5, the back pressure generated by the condensed water in the liquid storage chamber 5 on the diffusion tube 3 will cause the uncondensed steam in the diffusion tube 3 to be released from the exhaust hole 33, thereby reducing the temperature fluctuation of the condensed water. Therefore, the interference of the temperature fluctuation of the condensed water on the conductivity is reduced, which is conducive to the stability of the conductivity test of the condensed water.

[0050] Regarding the conductivity detection of condensed water, in some embodiments of the present application, combined with Figure 1 As shown, a conductivity cell 6 is provided in the liquid storage chamber 5, and one end of the diffusion tube 3 extending into the liquid surface of the liquid storage chamber 5 extends into the conductivity cell 6, so that the condensed water flowing out of the diffusion tube 3 will enter the conductivity cell 6, so that the conductivity of the condensed water flowing out of the diffusion tube 3 can be detected in real time by using the detection element in the conductivity cell 6. In the present application, since the non-condensable gas has been separated from the condensed water flowing out of the diffusion tube 3, the stability of the conductivity detection result of the condensed water is ensured.

[0051] Combination Figure 1 and Figure 3 As shown, a drain port 61 is provided at the bottom of the conductivity cell 6, and the drain port 61 is connected to the liquid storage chamber 5. Condensed water in the conductivity cell 6 can be discharged from the drain port 61 into the liquid storage chamber 5, thereby achieving a drain function.

[0052] The pure steam sampling device has a steam purge function. When the steam purge function is turned on, the high-temperature steam entering the condensation chamber 12 from the steam inlet 121 can flow into the conductivity cell 6 through the diffusion tube 3, and can also continue to flow into the liquid storage chamber 5 through the conductivity cell 6, thereby utilizing the high-temperature steam for purge sterilization.

[0053] Combination Figure 1 and Figure 2 As shown, an exhaust port 51 is provided at the top of the liquid storage chamber 5, and the liquid storage chamber 5 is connected to the separation chamber 13 through the exhaust port 51. In this way, as the condensed water enters the liquid storage chamber 5 from the diffusion tube 3, the liquid level of the condensed water in the liquid storage chamber 5 will rise, so that the air above the liquid level is discharged to the separation chamber 13 through the exhaust port 51. Therefore, under this structural setting, it is helpful to reduce the blocking effect of the air in the liquid storage chamber 5 on the outflow of the condensed water in the diffusion tube 3 through the condensed water, so that the condensed water in the diffusion tube 3 can flow into the liquid storage chamber 5 under its own gravity.

[0054] Combination Figure 2 and Figure 4As shown, in some embodiments, the pure steam sampling device includes a partition plate 7, which is arranged in the separation chamber 13, and the partition plate 7 divides the separation chamber 13 into an upper chamber 131 and a lower chamber 132. In this embodiment, the edge of the partition plate 7 has a notch 71, and the notch 71 connects the upper chamber 131 and the lower chamber 132. Thereby, the non-condensable gas is separated and discharged from the condensed water in time. The partition plate 7 is provided with a perforation 72, and the diffusion tube 3 is penetrated through the perforation 72 and sealed to the side wall of the perforation 72. The sealing connection method includes but is not limited to welding or sandwiching a sealing ring between the perforation 72 and the diffusion tube 3. The shape of the notch 71 formed by the edge of the partition plate 7 includes but is not limited to a crescent, a rectangle or a triangle.

[0055] Combination Figure 5 and Figure 6 As shown, the exhaust hole 33 is located between the partition plate 7 and the baffle wall 11, so that the exhaust hole 33 is connected to the upper chamber 131. Since the upper chamber 131 is connected to the lower chamber 132 through the notch 71, the non-condensable gas separated by flash evaporation in the diffusion tube 3 is discharged from the exhaust hole 33 and then passes through the upper chamber 131 and the notch 71 in sequence into the lower chamber 132.

[0056] Combination Figure 1 and Figure 5 As shown, the outer wall of the separation chamber 13 is provided with a condensate discharge port 15, and an inner circulation pipe 8 is provided in the liquid storage chamber 5. One end of the inner circulation pipe 8 is connected to the bottom of the liquid storage chamber 5, and the other end is connected to the condensate discharge port 15. A one-way valve can be provided on the inner circulation pipe 8 to ensure the closed and clean system. When the one-way valve is opened, the condensate in the liquid storage chamber 5 flows continuously through the inner circulation pipe 8 to the condensate discharge port 15 for discharge by relying on static pressure. With this structural setting, the discharge of the condensate is continuous and stable.

[0057] Combination Figure 7 As shown, a sampling valve 9 is provided below the liquid storage chamber 5, and the sampling valve 9 includes but is not limited to a sterile diaphragm valve. A water outlet 91 is provided at the bottom of the sampling valve 9. When the sampling valve 9 is opened, the condensed water in the liquid storage chamber 5 is discharged through the water outlet 91 of the sampling valve 9. In this way, the self-draining function of the pure steam sampling device when it is shut down can be realized.

[0058] Combination Figure 5 and Figure 7 As shown, in the embodiment in which the sampling valve 9 is arranged below the liquid storage chamber 5, a guide groove 92 communicating with the liquid storage chamber 5 is arranged on the side of the valve seat of the sampling valve 9 facing the liquid storage chamber 5, and one end of the inner circulation pipe 8 is inserted into the guide groove 92 and communicated with the liquid storage chamber 5 through the guide groove 92. In this embodiment, the other end of the inner circulation pipe 8 can be penetrated through the top of the liquid storage chamber 5 and communicated with the condensate discharge port 15 through a pipeline.

[0059] It should be noted that, in the present application, the liquid storage chamber 5 may also be a tank or tube structure. In some embodiments, the tank or tube structure forming the liquid storage chamber 5 may be connected to the tank 1 forming the condensation chamber 12 and the separation chamber 13 by welding or bolting. In order to ensure the sealing of the connection between the cavities, welding or clamping of sealing rings may be adopted at the connection position to achieve sealing between each other.

[0060] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the inventive concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
