A variable frequency magnetized brackish water jet oxygenation device based on alternating flow channels

Abstract

The invention discloses a variable-frequency magnetization brackish water jet oxygenation device based on alternating flow channels. The variable-frequency magnetization brackish water jet oxygenationdevice comprises a variable-frequency magnetization brackish water treatment apparatus and an outer-layer circular pipe. A water delivery opening is formed in an end of the outer-layer circular pipe,a middle-layer sleeve is further nested into the outer-layer circular pipe, one end, which is close to the water delivery opening, of the middle-layer sleeve is closed, an inner-layer sleeve is further nested into the middle-layer sleeve, openings are formed in two ends of the inner-layer sleeve, the outer diameter of the inner-layer sleeve is as same as the inner diameter of an output end of theouter-layer circular pipe, and a coil is spirally wound on the outer wall of the outer-layer circular pipe and is connected to positive and negative poles of a frequency conversion circuit board of the variable-frequency magnetization brackish water treatment apparatus. The variable-frequency magnetization brackish water jet oxygenation device has the advantages that magnetization, activation andoxygenation treatment can be repeatedly performed on brackish water with different degrees of hardness and viscosity, different temperatures and different PH (potential of hydrogen) values in electromagnetic fields with alternating frequencies by the variable-frequency magnetization brackish water jet oxygenation device with the alternating flow channels, and accordingly comprehensive efficient magnetization, oxygenation and activation effects can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation and water treatment, and relates to a frequency conversion magnetized brackish water aeration device based on an alternating flow channel. Background technique [0002] Brackish water replaces part of fresh water for agricultural irrigation, which can alleviate the shortage of fresh water resources to a certain extent, but the problems of soil salt accumulation and crop yield reduction caused by brackish water irrigation have always been the focus and difficulty of research. The latest research also shows that brackish water is rich in a large amount of salt ions, which greatly reduces its own oxygen-dissolving capacity. Long-term use of brackish water for field irrigation will greatly reduce the dissolved oxygen in the soil rhizosphere, threatening crops. The growth of aerobic microorganisms in the root system and rhizosphere reduces the root activity of crops and the efficiency o...
