Description

Technical Field

[0001] The utility model relates to a resin transfer device for an ion resin exchanger, belonging to the technical field of water treatment. Background Art

[0002] Ion exchange resins are widely used in the water treatment industry. Their function is to reversibly exchange ions in water to purify water quality.

[0003] In actual industrial applications, ion exchange resins are usually loaded in ion exchangers. The appropriate exchanger and resin loading amount are selected according to the production capacity. The ion exchanger is a closed container with various components such as a middle discharge device and a water distribution device installed inside for the operation and regeneration of the exchanger. When inspecting the internal components of the exchanger, the ion exchange resin loaded inside the exchanger needs to be manually emptied, which consumes time and labor costs.

[0004] At present, the water treatment system of the combustion process of the production control center is equipped with a mixed ion resin exchanger, and each exchanger is loaded with 10 tons of ion exchange resin. When the resin is transported, the ion exchange resin inside the exchanger is usually removed to the outside of the exchanger manually through the manhole of the exchanger.

[0005] Although the ion exchange resin can now be transported under pressure by injecting water into the exchanger to increase the pressure, that is, connecting a temporary pipeline to pressurize the ion exchange resin inside the exchanger for maintenance to the spare exchanger; however, the pressure transport requires a spare exchanger to store the exchange resin to be transported, the equipment cost is high, and the transport operation is cumbersome and risky, and it is easy to leak the resin, causing the resin to be lost. On the other hand, too high an operating pressure will cause damage to the resin particles and reduce the resin performance. Utility Model Content

[0006] The purpose of the utility model is to provide a resin transfer device for an ion resin exchanger, which can effectively solve the above-mentioned problems.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] It includes an ion exchanger and a transfer device arranged on the ion exchanger; the transfer device includes a resin delivery pipe and a delivery control valve; the resin delivery pipe is connected to the ion exchanger, and the delivery control valve is installed on the resin delivery pipe; a flushing water valve is also arranged on the resin delivery pipe, and the flushing water valve is arranged on the resin delivery pipe between the delivery control valve and the ion exchanger.

[0009] Furthermore: a collecting container is also provided at the lower end of the resin delivery pipe.

[0010] Further: the resin delivery pipe is a right-angle pipe, and the flushing water valve is horizontally installed at the corner of the resin delivery pipe.

[0011] Further: the reverse transport device is installed on the inspection hand hole at the bottom of the ion exchanger.

[0012] The beneficial effects are:

[0013] Ion exchange resin is made of polyethylene spheres with a diameter of 0.3-1.0 mm and a density of 1.04-1.3 g / cm3. It has a certain fluidity when mixed with water. Using this characteristic, a resin transfer device for ion resin exchangers is designed. It is installed in the hand hole at the bottom of the resin exchanger and uses the fluidity of wet resin to transfer the resin out of the exchanger.

[0014] 1) According to the structure of the ion resin exchanger, select the position of the resin transfer interface, make and install the ion resin transfer device, which is composed of a resin delivery pipe, a delivery control valve, a delivery flushing valve, etc., and becomes a separate set of detachable and reusable devices.

[0015] 2) The resin transfer device is usually installed on the inspection hand hole at the bottom of the ion resin exchanger (connected with a standard flange). During the resin transfer process, the ion resin exchanger is first filled with water (just cover the resin layer) to keep the resin wet. After the device is connected, the delivery flushing valve can be opened, and water can be injected into the exchanger through the transfer device to increase the fluidity of the resin. Then the delivery control valve is adjusted to a suitable opening, and the resin inside the exchanger can flow to the collection container by gravity. After the resin transfer is completed, the device can be dismantled. The device has a simple structure and can be reused.

[0016] 3) This device can realize the normal pressure transfer of ion exchange resin, and has the advantages of high safety, small resin loss, and small amount of water used for transfer. It can be widely used in the cleaning and transfer of ion exchange resin. BRIEF DESCRIPTION OF THE DRAWINGS
