Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ion exchange columns and relates to an automatic waste discharge system for ion exchange columns. Background Art
[0002] An ion exchange column refers to a columnar pressure vessel used for ion exchange reactions. The solution to be treated is introduced from one end of the column and fully contacts the fixed ion exchange resin layer or flowing ion exchange resin bed in the column to carry out ion exchange.
[0003] At present, ion exchange columns mostly use compressed air, compressed nitrogen and other methods to drain excess water from the ion exchange column to reduce the time required for the ion exchange column to feed and run. This method requires constant attention to the liquid level of the ion exchange column during the drainage process to avoid oxidation of the ion exchange resin due to the low liquid level. Due to various factors such as air flow rate, drainage time and valve size, this method causes the liquid level in the ion exchange column to be highly unstable, which is not conducive to maintaining production. At the same time, it wastes employees' working time, increases their workload and increases the adverse effects of compressed gas on ion exchange columns. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an automatic waste discharge system for an ion exchange column, which reduces the consumption of compressed air, shortens the working time of employees, and automatically discharges water and waste.
[0005] The utility model is implemented in this way, providing an automatic waste discharge system for an ion exchange column, comprising a waste discharge pipeline arranged at the bottom of the ion exchange column and a waste discharge valve arranged on the waste discharge pipeline, further comprising an air-breaking valve arranged at the top of the waste discharge pipeline, further comprising an emptying pipeline arranged at the top of the ion exchange column and an emptying valve arranged on the emptying pipeline, wherein the height of the top of the waste discharge pipeline is higher than the filling height of the exchange resin filled in the ion exchange column.
[0006] Furthermore, the height of the top of the waste discharge pipeline is higher than the filling height of the exchange resin filled in the ion exchange column by 0-2 m.
[0007] Compared with the prior art, the automatic waste discharge system of the ion exchange column of the utility model includes a waste discharge pipeline and a waste discharge valve arranged on the waste discharge pipeline, and also includes a breaker valve arranged at the top of the waste discharge pipeline, and also includes an emptying pipeline arranged at the top of the ion exchange column and an emptying valve arranged on the emptying pipeline, wherein the height of the top of the waste discharge pipeline is higher than the filling height of the exchange resin filled in the ion exchange column. The utility model realizes automatic water and waste discharge of the ion exchange column, does not require manual intervention during waste discharge, and also reduces compressed air consumption and shortens employee working hours. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 The figure is a schematic diagram of the structural principle of a preferred embodiment of the automatic waste discharge system of the ion exchange column of the utility model. DETAILED DESCRIPTION
[0009] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0010] Please refer to Figure 1 As shown, a preferred embodiment of the automatic waste discharge system of an ion exchange column of the utility model includes a waste discharge pipeline 2 arranged at the bottom of the ion exchange column 1 and a waste discharge valve 3 arranged on the waste discharge pipeline 2, and also includes a breaker valve 4 arranged at the top of the waste discharge pipeline 2, and also includes an emptying pipeline 5 arranged at the top of the ion exchange column 1 and an emptying valve 6 arranged on the emptying pipeline 5, wherein the height of the top of the waste discharge pipeline 2 is higher than the filling height of the exchange resin A filled in the ion exchange column 1, and is the same as the liquid level height in the ion exchange column.
[0011] The height of the top of the waste discharge pipe 2 is set to be higher than the filling height of the exchange resin A filled in the ion exchange column 1, and the air-breaking valve 4 is set. The purpose is to prevent the liquid in the ion exchange column from being completely emptied due to the siphon phenomenon during the waste discharge process of the ion exchange column 1, thereby causing the ion exchange resin to be oxidized.
[0012] The height of the top of the waste discharge pipeline 2 is higher than the filling height of the exchange resin A filled in the ion exchange column 1 by 0-2 m.
[0013] The height of the top of the waste discharge pipe 2 is set at 1.5m higher than the filling height of the exchange resin A inside the ion exchange column 1, and the time required to lower the liquid level is 5h. The height of the top of the waste discharge pipe 2 is set at 2.0m higher than the filling height of the exchange resin A inside the ion exchange column 1, and the time required to lower the liquid level is 4h.
[0014] When it is necessary to discharge the waste water in the ion exchange column 1, the drain valve 6, the waste valve 3 and the air-breaking valve 4 are opened to discharge the waste water through the waste discharge pipeline 2. Each time the waste water is discharged, the liquid level in the ion exchange column 1 drops to a consistent height, which reduces the requirements for employee experience and proficiency. After the waste water is discharged, the drain valve 6, the air-breaking valve 4 and the waste valve 3 are closed.
[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
