Ultrasonic wave high energy oxygen iron removal device

Abstract

The invention discloses an ultrasonic wave high energy oxygen iron removal device. The device includes a stock solution tank and an iron removal reaction tower. The stock solution tank is respectivelyprovided with a liquid inlet pipe, a liquid extraction pipe, a liquid return pipe and an infusion pipe. The iron removal reaction tower is internally divided into a gas-liquid mixing area and a reaction area longitudinally, the gas-liquid mixing area is located above the reaction area, the gas-liquid mixing area is internally provided with a gas-liquid contactor, the top end of the gas-liquid contactor extends upward out of the iron removal reaction tower and is communicated with the liquid extraction pipe, the bottom is an injection part for ejecting the liquid in the gas-liquid contactor and sucking the air in the gas-liquid mixing area into the gas-liquid contactor, and the iron removal reaction tower is also internally provided with at least one ultrasonic generator. The device provided by the invention avoids the use of hydrogen peroxide, does not produce sewage in the whole process, breaks through the technical bottleneck of using a large amount of hydrogen peroxide in the past,not only has good iron removal effect on the stock solution, and also does not produce oxide product in the whole process, thus improving the product quality and output.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an ultrasonic high-energy oxygen iron removal device. Background technique [0002] In the existing water treatment field, for the liquid iron removal process, hydrogen peroxide is usually added to the zinc sulfate solution, and the solution is stirred to react, so as to achieve the effect of iron removal. This method actually has the following disadvantages: [0003] 1. Since hydrogen peroxide must be used, a large amount of sewage will be generated in the whole process, and the subsequent treatment process is troublesome, which is not only time-consuming and labor-intensive, but also costs a lot. [0004] 2. Since hydrogen peroxide must be used, more product oxides will be produced, resulting in a reduction in final output and affecting product quality. Contents of the invention [0005] Purpose of the invention: In order to overcome the deficiencies in t...
