Abstract
Description
Technical Field
[0001] The utility model relates to an ion exchange column with a novel structure and belongs to the field of ion exchange. Background Art
[0002] At present, solid-liquid ion exchange is mainly completed in a columnar ion exchanger. First, the solid to be pre-exchanged is put into the exchange column, and then liquid is introduced into the column to complete the exchange task. Generally, the discharged liquid is drained completely, and the solid material is discharged from the exchange column. The solid particle material is carried away from the exchange column by the way of turbulent liquid entrainment. However, in order to prevent the exchange liquid from carrying the solid material out of the exchange column and causing material loss during the exchange, generally a water cap or a filter element is used to intercept the solid particle material. The following disadvantages of the water cap and the filter element are found in daily applications: the manufacturing cost is high, the installation workload is large, and the reliability is poor. If one of hundreds of water caps falls off, a material leakage accident will occur. The water cap and the filter element are installed in the exchange column, which is easy to cause bridging, adhesion and wall hanging of solid materials, and is very unfavorable for the complete discharge of solid materials. The filtration accuracy of the water cap and the filter element can only reach 0.1 mm, and the manufacturing accuracy is difficult to control. Content of the Utility Model
[0003] According to the above deficiencies in the structure of the existing exchange column, the problem to be solved by the utility model is to provide a novel exchange column with simple internal structure, low manufacturing cost, more reliable operation, faster and more complete entry and exit of solid particles, and water resource saving.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] An ion exchange column with a novel structure includes an upper head, a cylinder body, a lower head and an alloy filter screen. The upper head is fixedly connected to the top end of the cylinder body, and the lower head is fixedly connected to the lower end of the cylinder body. The lower head is provided with a material outlet, an exchange liquid inlet, a vent port and a maintenance discharge port. The alloy filter screen is arranged inside the lower head and divides the inner wall of the lower head into an upper wall and a lower wall. The material outlet is arranged on the upper wall, and the exchange liquid inlet, the vent port and the maintenance discharge port are arranged on the lower wall. A material inlet, a vent port, a pressurization port and an exchange liquid outlet are opened at the top of the upper head. An exchange filter screen is arranged at the exchange liquid outlet.
[0006] Preferably, the cylinder body is provided with a temperature measuring port, a pressure measuring port, a viewing window and an ear.
[0007] Preferably, the inclination angle of the alloy filter screen is greater than 4°36′, and the lowest side is on the same side as the material outlet, so that the solid material can be more easily discharged from the material outlet.
[0008] Preferably, the vent port and the maintenance discharge port communicate with the bottom end of the lower head through a tee.
[0009] Preferably, the window is provided at the lower part of the cylinder body, the temperature measuring port is provided at the upper part of the cylinder body, and the supporting ear is provided at the middle part of the cylinder body.
[0010] Preferably, a secondary filter screen is provided at the maintenance discharge outlet. To prevent materials from being discharged from the air defense port when the alloy filter screen is damaged, resulting in losses.
[0011] The materials enter the exchange column through the material inlet of the upper head and fall on the alloy filter screen. The exchange liquid enters the exchange column through the exchange liquid inlet of the lower head and fully exchanges and washes with the materials. To prevent the exchange liquid from carrying the materials out of the exchange column, a highly precise exchange filter screen is installed at the exchange liquid outlet of the upper head. When the exchange and washing are qualified, the residual exchange liquid is discharged through the evacuation port, and then water is first injected and high-pressure air is introduced through the top pressurization port for pressurization. The materials are discharged from the material outlet of the exchange column, and the air residual pressure is discharged through the evacuation port.
[0012] The beneficial effects of the present utility model are as follows:
[0013] The present utility model designs the exchange column into three parts. The new alloy filter screen has a larger filtering area and higher precision, and is inclined and installed in the lower head part. The liquid materials are more easily drained, and the solid particle materials are transferred out more cleanly and thoroughly.
[0014] The structure of the present utility model is simple, easy to maintain, and reliable in operation. An exchange liquid filter screen is installed inside the exchange liquid outlet of the upper head to prevent material loss. All maintenance of the exchange column can be completed by disassembling the upper and lower heads, without entering the inside of the exchange column, avoiding the risk of working in a confined space.
