Hydraulic jet magnetic resin adsorptive reactor

Abstract

The invention provides a hydraulic jet magnetic resin adsorptive reactor, which is used for an adsorptive reaction of particle magnetic resin with the diameter of between 60 and 150 mu m. Two thirds of the upper part of the reactor body is an open cylinder, while one third of the bottom is a cone with the gradient of 60+ / -5 degrees; a gas-water-solid three phase separator is arranged inside the reactor body; a stirrer is arranged in the reactor, and the diameter of the stirrer is one fourth to one third of the diameter of the cross section of the reactor body; a radial water collecting weir is arranged at the position 0.5+ / -0.1m under the top part of the reactor; the reactor is provided with a water inlet, a water outlet, an air outlet and a service port; the water inlet is arranged on the bottom lateral surface of the reactor, and is provided with a hydraulic jet device which is provided with an air inlet device; and the water outlet is arranged at the effluent part of the water collecting weir. Inflow water adopts jet inflow of a jet pipe, and air-water mixture generated by jet promotes the resin to be sufficiently contacted with water; and the arrangement of the three phase separator improves the separation efficiency of the resin and the water and reduces the wastage rate of the resin.

Description

technical field [0001] The invention relates to a resin adsorption reaction device, in particular to a hydraulic jet type magnetic resin adsorption reaction device, especially a solid spherical particle magnetic resin adsorption reaction device with a diameter of 60-150um. Background technique [0002] In the treatment of water supply and special chemical wastewater, it is often necessary to use ion exchange resins to treat industrial solutions to achieve decolorization, softening, clarification, decontamination, etc. When using a solution, not only there are problems such as slow action speed and complicated pretreatment process, but also the separation of the resin from this kind of solution is quite difficult, and the regeneration efficiency is low. The particle solid magnetic resin overcomes the shortcomings of the above resins, and has a large specific surface area. Strong decontamination ability, easy to separate after adsorption, no internal pore blockage problem, hig...

Problems solved by technology

[0002] In the treatment of water supply and special chemical wastewater, it is often necessary to use ion exchange resins to treat industrial solutions to achieve decolorization, softening, clarification, decontamination, etc. When using a solution, not only there are problems such as slow action speed and complicated pretreatment process, but also the separation of the resin from this kind of solution is quite difficult, and the regeneration efficiency is low. The particle solid magnetic resin overcomes the shortcomings of the above resins, and has a large specific surface area. Strong decontamination ability, easy to separate after adsorption, no internal pore blockage problem, high degree of activity recovery after regeneration, long service life and many other advantages, but when the magnetic resin adopts the traditional fixed bed or suspension bed as the resin adsorption reactor The magnetic resin with high layer pressure is easy to be compacted and broken due to mutual attraction, the bed layer is easy to channel, and the overall contact area is small; the resin is easy to be lost due to the small particles during backwashing; the adsorption and regeneration are intermittently operated, and continuous operation cannot be realized. Seriously affect the normal performance of the adsorption performance of particulate solid magnetic resin, it is necessary to develop an adsorption reactor suitable for particulate magnetic resin
