Abstract

The invention relates to a magnetic-acoustic field synergistically enhanced sponge iron water deoxygenizing component, which comprises flanges arranged at left and right ends of a shell, at least one deoxygenizing unit located on the shell and a partition arranged between two adjacent deoxygenizing units, wherein the deoxygenizing unit is characterized in that filter nets are arranged at the left and right ends inside the shell, radial ultrasound radiation pipes are arranged at the center positions of the front and rear inner walls of the shell, a front power ultrasonic transducer is arranged on the front outer wall of the shell, a rear power ultrasonic transducer is arranged on the rear outer wall of the shell, the radiation end of the front power ultrasonic transducer is connected with the front ends of the radial ultrasound radiation pipes inside the shell, the radiation end of the rear power ultrasonic transducer is connected with the rear ends of the radial ultrasound radiation pipes inside the shell, an upper permanent magnet is located at the inner top of the shell, a lower permanent magnet is located at the inner bottom of the shell, the lower end surface of the upper permanent magnet and the upper end surface of the lower permanent magnet have opposite polarities, and sponge iron particles are filled between the upper permanent magnet and the lower permanent magnet and between the two filter nets.

Description

technical field [0001] The invention belongs to the technical field of oxygen removal for industrial water, and in particular relates to a magnetic-acoustic field synergistically strengthened oxygen-removing component for a sponge molten iron body. Background technique [0002] In industrial water, in order to reduce the corrosion of facilities such as industrial boilers and circulating cooling, it is necessary to remove or reduce the content of dissolved oxygen in the water. Therefore, a series of methods and devices for removing dissolved oxygen in water have been produced. [0003] At present, the dissolved oxygen removal technologies in water mainly include thermal deaeration, vacuum deaeration, analytical deaeration, chemical deaeration, etc. Thermal deaeration, vacuum deaeration, and analytic deaeration are physical water body dissolved oxygen removal methods based on Henry’s principle. Although these methods are currently the main methods for water body deaeration, t...

Problems solved by technology

[0004] First, under normal conditions, the amount of commonly used gases such as chemically adsorbed oxygen on the surface of iron is very small, and the process is also very slow, thus restricting its deoxygenation rate; The dissolved oxygen content in the depth of the filter layer is very low, which cannot make Fe(OH) 2 All converted to Fe(OH) 3 , so there is a small amount of F in the effluent e +2 Ions; third, the product Fe(OH) of the sponge iron water body deoxygenation reaction 3 It is a floc, which will stay and deposit in the pores of sponge iron and affect the subsequent water O 2 Contact with sponge iron surface

The traditional method is to backwash with water to remove Fe(OH) 3 flocs, which not only complicates the structure of the equipment, but also must be equipped with more than two sets of independently working oxygen removal systems to solve the problem of interrupted water discharge caused by flushing

The above aspects restrict the popularization and application of sponge iron deoxidation technology
