Efficient softening and crystallizing equipment for reverse osmosis concentrated water

Abstract

The invention discloses efficient softening and crystallizing equipment for reverse osmosis concentrated water. The efficient softening and crystallizing equipment comprises a softening and crystallizing equipment body, power supply equipment and electromagnetic equipment; the softening and crystallizing equipment body is of a hollow structure, a water inlet is formed in the bottom of the softening and crystallizing equipment body, a water outlet is formed in the top of the softening and crystallizing equipment body, a seed crystal or filter material feeding port is formed in the side face of the top of the softening and crystallizing equipment body, and a seed crystal or filter material discharging port is formed in the side face of the bottom of the softening and crystallizing equipment body. An acid-base agent feeding port and a softening agent feeding port are formed in the side face of the softening and crystallizing equipment body, the softening and crystallizing equipment body is sleeved with the electromagnetic equipment, the power supply equipment is connected with the electromagnetic equipment, and the equipment effectively avoids the problems that the softening effect is affected by a scale inhibitor and the bottom of the equipment scales, the water distribution device is kept smooth, so that the flow state in the whole softening and crystallizing equipment is stable, the softening and crystallizing effect is good, and the treatment efficiency is high.

Description

technical field [0001] The invention relates to softening and crystallization equipment, in particular to a high-efficiency softening and crystallization equipment for reverse osmosis concentrated water. Background technique [0002] At present, there are various forms of softening treatment equipment in the field of water treatment. Crystallization granulation fluidized bed equipment has the characteristics of low moisture content in sludge discharge, saving sludge dewatering unit, small footprint, low investment and operating costs, etc. , has attracted much attention. Most of the existing crystallization and granulation fluidized bed equipment focuses on innovation in uniform water distribution, dosing equipment, seed crystal dosing and pH adjustment to ensure the softening effect of the effluent. However, in the actual operation process, due to the oversaturation of the ion concentration in the bottom area of ​​the fluidized bed after dosing, large particles will deposi...

AI Technical Summary

Problems solved by technology

However, in the actual operation process, due to the oversaturation of the ion concentration in the bottom area of ​​the fluidized bed after dosing, large particles will deposit at the bottom, causing a large amount of calcium scale to bond with the crystal seed or filter material into large pieces, blocking the dosing port and affecting water distribution. , resulting in the phenomenon of bias flow in the fluidized bed after long-term operation, and when the bonding volume is large enough, it will affect the efflux of crystal seeds, and the softening treatment efficiency will decrease

In addition, since reverse osmosis concentrated water contains a certain concentration of scale inhibitors, after entering the crystallization granulation fluidized bed, there is a problem that the softening efficiency decreases
