Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature sampling rack ion exchange equipment, in particular to an ion exchange column. Background Art

[0002] Under the pressure of the feed water pump, the feed water passes through heating, evaporation and superheating in turn to generate superheated steam with a certain pressure and temperature. This kind of boiler is called a direct current boiler. When the direct current boiler is in operation, some impurities in the feed water are carried away with the steam. Since there is no sewage system, the direct current boiler has relatively high requirements for the quality of feed water. Hydrogen conductivity is an important indicator for detecting the quality of feed water. When the feed water passes through the ion exchange column, the ammonia ions in the feed water are exchanged and the hydrogen ions generated combine with hydroxide to generate water. The hydrogen conductivity represents a conductivity that more accurately reflects the water quality by screening out ammonia in the feed water. After measuring the hydrogen conductivity, the content of anions in the feed water, that is, the content of impurities in the feed water, can be calculated based on the hydrogen conductivity.

[0003] In the water vapor monitoring of DC furnaces, hydrogen conductivity is one of the most important indicators. The laboratory personnel cannot compare it through manual measurement, and the accuracy of the monitoring instrument cannot be accurately judged when the water quality is abnormal, so the quality of chemical monitoring is reduced.

[0024] Please refer to Figure 1 In order to solve the problem of low accuracy in judging whether the water quality of the feed water meets the standard according to the measured hydrogen conductivity, the utility model proposes an ion exchange column 100, comprising:

[0025] A column 1 and a connecting component, wherein the column 1 is formed with an exchange chamber; the connecting component comprises an inlet pipe 21, an outlet pipe 22 and a detection branch pipe 23; the inlet pipe 21 is connected to the column 1 and is connected to the exchange chamber; the outlet pipe 22 is connected to the column 1 and is connected to the exchange chamber, and an end of the detection branch pipe 23 away from the outlet pipe 22 is used to connect a portable conductivity meter 3; a valve 231 is provided on the pipeline of the detection branch pipe 23 located between the outlet pipe 22 and the portable conductivity meter 3, and the valve 231 is used to control the on-off of the detection branch pipe 23.

[0026] In the technical solution of the utility model, the feed water after ion exchange flows out from the water outlet pipe 22, and the valve 231 on the detection branch pipe 23 can be opened to manually measure the hydrogen conductivity; this allows the laboratory personnel to manually measure and compare the hydrogen conductivity, solving the problem that the hydrogen conductivity cannot be measured manually, thereby improving the accuracy of judging whether the water quality of the feed water meets the standard based on the measured hydrogen conductivity.

[0027] In one embodiment of the utility model, the water outlet pipe 22 is inserted into the column 1, and the outlet of the water outlet pipe 22 is located in the exchange chamber and is arranged near the bottom wall of the exchange chamber. Due to the influence of gravity, the feed water entering the ion exchange column 100 will flow to the bottom of the column 1; the outlet of the water outlet pipe 22 is arranged at the bottom of the column 1, which can prevent part of the feed water from staying at the bottom of the column 1 for a long time, thereby enhancing the fluidity of the feed water in the exchange chamber; in this way, the feed water can fully exchange ions with the resin in the exchange chamber, so that more accurate hydrogen conductivity data can be measured, thereby improving the accuracy of judging whether the feed water quality meets the standard based on the measured hydrogen conductivity.

[0028] In one embodiment of the utility model, the connecting component further includes a filter 24, and the filter 24 is arranged at the outlet of the water outlet pipe 22 in the exchange chamber. The filter 24 is arranged at the outlet of the water outlet pipe 22 to prevent the resin from flowing out of the exchange chamber through the water outlet pipe 22, thereby ensuring that the feed water can fully exchange ions with the resin in the exchange chamber, so that more accurate hydrogen conductivity data can be measured, and thereby improve the accuracy of judging whether the feed water quality meets the standard based on the measured hydrogen conductivity.

[0029] The filter element 24 can be a filter screen or an activated carbon block. In one embodiment of the utility model, the filter element 24 is a filter screen, which can prevent the resin from flowing out of the exchange chamber through the outlet pipe 22 and will not affect the impurity content in the feed water, thereby improving the accuracy of judging whether the feed water quality meets the standard based on the measured hydrogen conductivity.

[0030] In one embodiment of the utility model, the water inlet pipe 21 is inserted into the column 1 and is located at the top of the column 1. Such a configuration allows the feed water to flow from the top of the column 1 to the bottom of the column 1, so that it can fully exchange ions with the resin in the column 1; in this way, more accurate hydrogen conductivity data can be measured to improve the accuracy of judging whether the feed water quality meets the standard based on the measured hydrogen conductivity.

[0031] In one embodiment of the utility model, the connecting component further includes a check valve 25, which is arranged on the pipeline of the water inlet pipe 21. The check valve 25 is arranged on the pipeline of the water inlet pipe 21 to prevent the feed water entering the exchange chamber from flowing back to the water inlet pipe 21, so that the feed water that has undergone ion exchange is mixed with the feed water that has not undergone ion exchange, thereby affecting the measurement result of the feed water hydrogen conductivity.

[0032] In one embodiment of the utility model, the connecting component also includes a flow meter 26, which is arranged on the pipeline of the water inlet pipe 21. The flow meter 26 can monitor the flow rate of the water supply in the water inlet pipe 21 in real time. By measuring the flow rate of the water supply in the water inlet pipe 21, the water inlet speed of the ion exchange column 100 can be accurately grasped, thereby monitoring the water flow in the treatment process in real time. If the flow rate is too high, the flow rate of the water supply through the ion exchange column 100 may be too fast, resulting in insufficient contact of the water supply in the ion exchange column 100, thereby reducing the treatment effect. On the contrary, if the flow rate is too low, it may cause stagnation of the water supply in the column, increase the treatment time and waste resources. Through the flow meter 26, the user can adjust the operating parameters according to the real-time data to optimize the treatment process and improve efficiency and economy.

[0033] In one embodiment of the utility model, the connecting component also includes a regulating valve 27, which is arranged on the pipeline of the water outlet pipe 22. The regulating valve 27 can be used to control the flow rate of the water outlet pipe 22 of the ion exchange column 100. By adjusting the opening of the regulating valve 27, the flow rate of the feed water in the water outlet pipe 22 can be adjusted to keep it within the required range, so as to ensure the stability of the water outlet flowing to the next process. At the same time, the regulating valve 27 can also be used to control the pressure of the water outlet pipe 22 of the ion exchange column 100; by adjusting the opening of the regulating valve 27, the pressure in the water outlet pipe 22 can be adjusted to ensure that the pressure during the water outlet is stable and meets the requirements; thereby preventing the water outlet pipe 22 from rupturing due to excessive pressure.

[0034] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
