Problems solved by technology

[0005] The advantage of microspherical adsorption or exchange resin is that the problem of internal diffusion is small, but when it is used in a fixed bed to treat a large amount of gas and liquid, there is a problem of high bed resistance, which limits the flow of liquid or gas, and requires a larger pressure head. Fan or pump, and it is easy to trap mechanical impurities and cause local blockage, so it cannot be applied in many occasions, or it is not easy to play an effective role, especially when dealing with fugitive exhaust gas with a large flow rate; if a bubbling bed or a fluidized bed is used, although The processing capacity is large, but there is a problem of insufficient processing accuracy, and a fan with a large pressure head is still required when processing gas

Embodiment 1

[0031] Dilute glue A of epoxy AB glue to the appropriate viscosity with thinner, add the required amount of glue B, mix quickly, take 120ml and spread it on a 300x400mm horizontal plate, with a depth of about 1mm, and 400g of polypropylene plastic balls with a diameter of 3mm. Apply glue on the surface of the glue plate three times. Immediately after the glue is applied, the plastic balls are moved one by one into the plate with a sufficient amount of macroporous strong acid cation exchange resin microspheres (type 732) with an average diameter of 1.0 mm. Shake the plate to make the surface of the plastic balls The resin microspheres were covered or nearly full, removed, and cured at room temperature in a fume hood to obtain the macroporous strongly acidic cation exchange resin low-resistance adsorbent of this embodiment. Take 20ml of the adsorbent and spread it in a horizontal plate, and judge that the adhesion rate of the resin microspheres on the surface of the plastic balls...

Abstract

The invention provides a low-resistance adsorbing material based on resin microspheres. The low-resistance adsorbing material has a boundary dimension much bigger than that of a microsphere, so that the resistance of a bed layer is relatively low when the adsorbing material is used for fixing a bed, meanwhile, the internal diffusion problem is relatively small, the adsorption and exchange capacity and precision are basically not decreased. The low-resistance adsorbing material is formed by bonding a spherical, strip-shaped, honeycombed, cylindrical or abnormal-shaped body with boundary dimension much bigger than that of the microsphere with a plenty of adsorbing or ion exchange resin microspheres, most openings of internal micropores of the resin microspheres in the outer surfaces of the microspheres are not blocked, and the resin microspheres are directly communicated with the outer surface of the adsorbing material or are communicated with the adsorbing material through ducts among the microspheres; and the low-resistance adsorbing material can be applied to the recycling of organic solvents, the tissue and non-tissue exhaust VOCs removal and the deoiling treatment of oil-containing water.

Description

technical field [0001] The invention relates to a resin adsorption material and its application, in particular to a low-resistance adsorption material based on resin microspheres and its application. Background technique [0002] In recent years, improving the environment has become a major demand for social development, and reducing pollutant emissions is the basis for solving problems. [0003] Under realistic conditions, the methods for reducing pollutant emissions, except for some that can reduce the amount of pollutants produced and reduce emissions by improving the main raw materials and key processes, or by transforming pollutants into harmless, low-efficiency Most of the pollutants that meet the discharge standards are achieved through adsorption and interception, and most of the pollutants are enriched and captured, and then specially treated or recycled, while the liquid, The discharge of gas meets the standard. Of course, some liquids and gases that have removed ...
