Embodiment 1

[0031] The device A of the present invention is composed of a device B and a device C, and the device B and the device C are combined in a complete set, and the device C is sleeved outside the device B to form the device A. Device B is a 250mL conical flask with an external grinding mouth; Device C has an internal grinding mouth to match device B, and device C is equipped with a piston, a ventilation tube, and a filter element. The designed device C has a large weight and is tightly seamed with the device B, which avoids the problem of being pushed up and broken during the experiment. After the resin-containing soaking solution is soaked at room temperature for 20 minutes, the resin and the soaking solution are quickly separated by using device A. The obtained soaking solution does not contain resin, thus avoiding the problem of inhaling the resin when the pipette removes the soaking solution and avoiding soaking The measurement error of the maximum strong group regeneration ca...

Embodiment 2

[0043] The difference from Example 1 is that the device B is a container with an outer grinding mouth, and the device C is a filter with an inner grinding mouth, and the inner diameter of the inner grinding mouth is the same as the outer diameter of the outer grinding mouth.

Embodiment 3

[0045] The difference from Example 1 is that the device B is a container with an inner grinding mouth, and the device C is a filter with an outer grinding mouth, and the inner diameter of the inner grinding mouth is the same as the outer diameter of the outer grinding mouth.

Abstract

The invention discloses an apparatus for determining the maximum strong group regeneration capacity of oxyhydrogen anion 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 intake in the process of removal of an immersion liquid through a pipet on the determination of the maximum strong group regeneration capacity of the oxyhydrogen anion 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, and particularly relates to a device for measuring the maximum strong group regeneration capacity of a hydroxide type anion exchange resin. technical background [0002] Anion exchange resins are widely used in power plants, pharmaceutical factories, and electronics industries, and play an important role in purifying water quality and removing anions and organics in water. The maximum strong group regeneration capacity is an important performance index of the hydroxide anion exchange resin. It is related to the quality of the resin product and the amount of water produced, as well as the price and interest between the supplier and the user, so the hydroxide anion is accurately determined The regeneration capacity of the largest strong group of the exchange resin is of great significance. [0003] National standard GB / T5760-2000 "Method for the determination of the exchange capacity of hydroxide t...
