Apparatus for determining exchange capacity of ion exchange resin

Abstract

The invention discloses an apparatus for determining the exchange capacity of ion exchange resin. The apparatus is composed of a device B and a device C, the device B is an open-ended container, the device C comprises a filter, the outlet pipeline of the device C is provided with a flow control device, and the opening of the device B is connected with the inlet end of the device C; when the flow control device is closed, a closed cavity is formed between the device C and the device B, and the volume of the cavity is kept unchanged; the device C is provided with a gas change tube, the bottom end of the gas change tube extends into the device B, the top end of the gas change tube extends to the outside of the device B, and the top end of the gas change tube is provided with a gas flow control device; and when in a stationary state, the bottom end of the gas change tube is positioned above the liquid level of a reaction liquid. The problems of influences of resin and immersion liquid cooling time difference, cooling mode difference and resin extraction in the immersion liquid removal process on the determination of the exchange capacity of ion exchange resin and on avoiding of bottle stopper breaking in test are solved.

Description

technical field [0001] The invention belongs to the field of power grid construction, in particular to a device for measuring the exchange capacity of ion exchange resins. technical background [0002] Ion exchange resins are widely used in power plants, pharmaceutical factories, and electronics industries, and play an important role in purifying water, removing anions and cations in water, and removing organic matter. Exchange capacity is an important performance index of ion exchange resins. It is related to the quality of resin products and water production, as well as the price and benefits between suppliers and users. Therefore, it is of great significance to accurately measure the exchange capacity of ion exchange resins. [0003] The total exchange capacity of ion exchange resin refers to the total amount of chemical groups that can undergo ion exchange reaction per unit quantity (weight or volume) of resin. The reaction temperature and equilibrium time between ion ex...

Problems solved by technology

Because the tapered stopper is pointed, use a heavy object to press the pointed object. Because the contact point is too small, the heavy object is not firmly pressed on the bottle stopper.

During the test, due to the high air pressure in the bottle, accidents occurred from time to time when the bottle cork was opened and fell to the ground and broke, which led to the termination of the test halfway, and the smooth progress of the test could not be guaranteed.
