Fluid bed type ion exchange water treatment device adopting electromagnetic vibration and provided with foam cushions for damping

Abstract

The invention discloses a fluid bed type ion exchange water treatment device adopting electromagnetic vibration and provided with foam cushions for damping. The device has the key characteristics that repeated conical funnel screen surfaces and bamboo hat screen surfaces in each tower body constitute multilayered support discs for dispersing resin, and water is taken as a medium carrier to transmit vibration, so that layer-by-layer falling and dispersing of resin are realized; resin on the conical funnel screen surfaces is transferred to the bamboo hat screen surfaces by the aid of central blanking pipes; the resin is transferred to the next conical funnel screen surface through micro-pressure opening which can be realized by elastic ring pieces on the edges of the bamboo hat screen surfaces; the resin is repeatedly diffused and falls off layer by layer, and finally, the resin is transferred and transported to a tower in the next work step by the aid of pumps and a Venturi ejection and absorption device at the corresponding tower bottom. The repeated conical funnel screen surfaces and bamboo hat screen surfaces in each tower body can sufficiently utilize buoyancy force, vibration and inclination to realize smooth falling and circulating of the resin, so that the contact time of the resin and a liquid phase is long, ion exchange is sufficient, liquid channeling and dead angles are avoided, automatic continuous operation is realized conveniently under the condition of efficient and uniform countercurrent mass transfer, and the device has an important application value.

Description

Technical field [0001] The invention relates to an electromagnetic vibration foaming cushion shock-absorbing fluid bed type ion exchange water treatment device. Background technique [0002] The softening treatment of water through ion exchange is widely used in the chemical, pharmaceutical, food and other fields. In addition, the treatment of boiler water uses the sodium ions in the cation exchange resin to exchange calcium and magnesium ions in the water to perform water Softening treatment to prevent boiler scaling and avoid safety accidents. [0003] After the resin adsorbs calcium and magnesium ions, the resin adsorption capacity can be regenerated with concentrated salt water, and the purpose of recycling can be achieved after washing. Ion exchange water treatment devices have several typical application modes in practical applications, such as fixed bed, floating bed, and fluidized bed. Among them, the fluidized bed is suitable for large flow and uninterrupted operation, an...

Problems solved by technology

Ion exchange water treatment devices have several typical application modes such as fixed bed, floating bed, and fluidized bed in practical applications. Among them, the fluidized bed is suitable for large flow and uninterrupted operation, and has the obvious advantage of high efficiency, but there are also resin and Short contact time of the liquid phase, insufficient ion exchange, and problems affecting ion exchange such as channel flow and dead ends make it difficult to achieve ion exchange under efficient and uniform counterflow mass flow conditions.
