Description

Technical Field

[0001] The present application relates to the technical field of gas detection, and in particular to a cooling and hydrophobic pretreatment device before measuring hydrogen leakage in steam. Background Art

[0002] In the related art, a hydrogen online analyzer is used to measure the amount of hydrogen leaked in steam. However, before the hydrogen online analyzer detects and analyzes the hydrogen content in the steam, only a cyclone refrigerator is used to cool the sample steam, and the gas after the cooling treatment is then sent to the hydrogen online analyzer. This sample steam pretreatment method has the following problems: only using a cyclone refrigerator results in poor cooling effect, so that the temperature of the gas entering the hydrogen online analyzer is still too high, which will damage the hydrogen online analyzer; after the cooling treatment, a lot of condensate accumulates, and the staff needs to manually drain the liquid regularly. Once the staff fails to drain the liquid in time, the condensate will enter the hydrogen online analyzer with the gas, which is easy to damage the hydrogen online analyzer; because the sample gas introduced into the hydrogen online analyzer does not meet the preset measurement gas conditions, it is easy to cause damage to the hydrogen online analyzer and measurement distortion, which in turn leads to the low accuracy of the hydrogen content detection result obtained according to the hydrogen online analyzer, which is easy to cause the process to misjudge the operation according to the hydrogen content detection result and cause shutdown.

[0019] In the related art, a hydrogen online analyzer is used to measure the amount of hydrogen leaked in steam. However, before the hydrogen online analyzer detects and analyzes the hydrogen content in the steam, only a cyclone refrigerator is used to cool the sample steam, and the gas after the cooling treatment is then sent to the hydrogen online analyzer. This sample steam pretreatment method has the following problems: only using a cyclone refrigerator results in poor cooling effect, so that the temperature of the gas entering the hydrogen online analyzer is still too high, which will damage the hydrogen online analyzer; after the cooling treatment, a lot of condensate accumulates, and the staff needs to manually drain the liquid regularly. Once the staff fails to drain the liquid in time, the condensate will enter the hydrogen online analyzer with the gas, which is easy to damage the hydrogen online analyzer; because the sample gas introduced into the hydrogen online analyzer does not meet the preset measurement gas conditions, it is easy to cause damage to the hydrogen online analyzer and measurement distortion, which in turn leads to the low accuracy of the hydrogen content detection result obtained according to the hydrogen online analyzer, which is easy to cause the process to misjudge the operation according to the hydrogen content detection result and cause shutdown.

[0020] In order to solve the above-mentioned problem, the present application proposes a cooling and draining pretreatment device before measuring hydrogen leakage in steam. The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0021] Reference Figure 1The present application provides a cooling and draining pretreatment device for measuring hydrogen leakage in steam, comprising: a steam input pipeline 110, a water cooling mechanism, a water washing tank 113, an automatic drain tank 120, a vortex refrigerator 114, a hydrogen online analyzer 115 and a condensate drain pipeline 116; the output end of the steam input pipeline 110 is connected to the input end of the water cooling mechanism, the output end of the water cooling mechanism is connected to the input end of the water washing tank 113, the steam output end of the water washing tank 113 is connected to the input end of the vortex refrigerator 114, the steam output end of the vortex refrigerator 114 is connected to the hydrogen online analyzer 115; the water washing tank 113 An overflow hole is provided at two-thirds of the tank body near the top, and the top input end of the automatic drain tank 120 is connected to the water washing tank 113 through the overflow hole, and the output end of the automatic drain tank 120 and the condensate output end of the vortex refrigerator 114 are both connected to the input end of the condensate drain line 116; the water washing tank 113 is used to transport the condensate accumulated after condensation of the sample vapor transported through the water cooling mechanism to the automatic drain tank 120 through the overflow hole when the condensate accumulates and reaches the preset overflow level of the water washing tank 113, and the automatic drain tank 120 is used to output the condensate to the condensate drain line 116 and discharge it from the condensate drain line 116.

[0022] It should be noted that the input end of the water cooling mechanism is arranged at the top of the water cooling mechanism, and the output end of the water cooling mechanism is arranged at the bottom of the water cooling mechanism; the steam output end of the water washing tank 113 and the input end of the water washing tank 113 are respectively arranged on both sides of the top of the water washing tank 113, the input end of the vortex refrigerator 114 and the steam output end of the vortex refrigerator 114 are respectively arranged on both sides of the top of the vortex refrigerator 114, and the condensate output end of the vortex refrigerator 114 is arranged at the bottom of the vortex refrigerator 114.

[0023] It should be noted that, by providing an automatic drain tank 120 , when the liquid level in the water wash tank 113 reaches a preset overflow level at two-thirds of the tank body near the top, the liquid can be automatically drained to prevent the liquid from entering the hydrogen online analyzer 115 .

[0024] It should be noted that when the liquid level reaches the preset overflow level by the overflow method, the excess accumulated liquid overflows; the automatic drainage function of the automatic drain tank 120 is utilized to realize automatic drainage, reduce labor waste, and there is no need to arrange special personnel for drainage, thereby reducing labor waste and achieving efficiency improvement and cost reduction; the liquid can be drained automatically as the process changes, and the hydrogen online analyzer 115 can be protected in a timely and effective manner.

[0025] In the present application, the steam input pipeline 110 is used to transport the sample steam to the water cooling mechanism, the water cooling mechanism is used to perform the initial cooling and cooling of the sample steam and transport the sample steam after the initial cooling to the water washing tank 113, the water washing tank 113 is used to perform water washing on the sample steam to separate the impurities, condensate and gas in the sample steam, and the sample gas obtained after separation is transported to the vortex refrigerator 114, and the impurities and condensate obtained after separation fall to the bottom of the water washing tank 113 due to gravity. When the condensate accumulated in the water washing tank 113 reaches the preset overflow level of the water washing tank 113, it flows into the automatic drain tank 120 through the overflow hole, and is output in turn through the automatic drain pipe and the condensate emptying pipeline 116. Through this setting, the present application can realize multiple cooling of the sample steam, and can automatically drain the condensate obtained after cooling, to ensure that the accumulated liquid will not be brought into the hydrogen online analyzer 115, and improve the instrument detection accuracy.

[0026] Reference Figure 1 It can be understood that the water cooling mechanism includes a first water cooling tank 111 and a second water cooling tank 112, the input end of the first water cooling tank 111 is connected to the output end of the steam input pipeline 110, the output end of the first water cooling tank 111 is connected to the input end of the second water cooling tank 112, and the output end of the second water cooling tank 112 is connected to the input end of the water washing tank 113.

[0027] It should be noted that by arranging the first water-cooling tank 111 and the second water-cooling tank 112 in the water cooling mechanism, the cooling effect on the sample vapor is improved, so that after the sample vapor that has been cooled and treated is transported to the water washing tank 113, it loses moisture and becomes a relatively dry gas, thereby further reducing the liquid content of the gas transported to the hydrogen online analyzer 115.

[0028] Reference Figure 1 It can be understood that the cooling and draining pretreatment device before measuring the leakage of hydrogen in the steam also includes a first drain valve 121 and a first drain pipeline 122. A first drain port is opened at the bottom of the automatic drain tank 120. The input end of the first drain pipeline 122 is connected to the automatic drain tank 120 through the first drain port. The output end of the first drain pipeline 122 is connected to the input end of the condensate emptying pipeline 116. The first drain valve 121 is arranged on the first drain pipeline 122.

[0029] It should be noted that, by setting the first drain line 122 and the first drain valve 121, the first drain port is opened at the bottom of the automatic drain tank 120, so that the condensate flowing into the automatic drain tank 120 flows to the condensate emptying line 116 through the first drain port and the first drain pipeline 122 in turn, and the first drain valve 121 is always in a half-open state to control the amount of condensate flowing from the bottom of the automatic drain tank 120 to the condensate emptying line 116, and the staff can adjust the amount of condensate flowing from the bottom of the automatic drain tank 120 to the condensate emptying line 116 through the first drain valve 121.

[0030] In some embodiments, the first liquid discharge valve 121 is always in a half-open state.

[0031] Reference Figure 1 It can be understood that the cooling and draining pretreatment device before measuring the leakage of hydrogen in the steam also includes a second drain valve 123 and a second drain pipeline 124. A second drain port is opened at two-thirds of the tank body of the automatic drain tank 120 near the top. The input end of the second drain pipeline 124 is connected to the automatic drain tank 120 through the second drain port, and the output end of the second drain pipeline 124 is connected to the input end of the condensate emptying pipeline 116. The second drain valve 123 is arranged on the second drain pipeline 124.

[0032] It should be noted that by opening a second drain port at two-thirds of the tank body of the automatic drain tank 120 near the top, the input end of the second drain line 124 is connected to the automatic drain tank 120 through the second drain port, and the output end of the second drain line 124 is connected to the input end of the condensate emptying line 116, so that when the condensate content in the automatic drain tank 120 reaches two-thirds of the total height, it overflows into the condensate emptying line 116 through the second drain port and the second drain line 124, thereby preventing the condensate in the automatic drain tank 120 from accumulating too much condensate in the automatic drain tank 120 due to the slow outflow speed from the first drain port at the bottom and then flowing back to the washing tank 113 from the top input end of the automatic drain tank 120, and the staff can adjust the amount of condensate flowing from the second drain port of the automatic drain tank 120 to the condensate emptying line 116 through the second drain valve 123.
