De-electronic jet aeration apparatus for irrigation brackish water

Abstract

The present invention discloses de-electronic jet aeration apparatus for irrigation brackish water. The apparatus includes a de-electronic device main body, the de-electronic device main body is connected with a grounding device through a conductor, and the de-electronic device main body is made of a metal material; the apparatus also includes an insulating plate, the insulating plate is providedwith an insulating support, and the de-electronic device main body is fixed on the insulating support through connection pieces; and one end of the de-electronic device main body is connected with a jet aeration pipeline and a fertilizing device in sequence. According to the apparatus provided by the present invention, the de-electronic device main body is subjected to grounding treatment, a partial micro current is formed in the pipeline, so that the physical and chemical properties of the brackish water can be effectively improved, and the oxygen dissolving capacity of the brackish water canbe improved; and the jet aeration pipeline is arranged, based on the principles of hydraulics and aerodynamics, pipeline negative pressure generated by jetting of a high-speed water flow is applied to automatically suck air into the pipeline, and the high-efficiency aeration of the irrigation brackish water is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation devices, and relates to a brackish water jet aeration device for de-electron irrigation. Background technique [0002] Our country is rich in underground brackish water resources. In areas where fresh water resources are insufficient, brackish water is usually used for irrigation. The scientific and rational development and utilization of brackish water irrigation is conducive to alleviating the shortage of fresh water resources, renewing groundwater resources, and building and protecting the ecological environment. In arid and semi-arid areas, film-covering irrigation, drip irrigation and brackish water irrigation have been organically combined to form a vital water-saving irrigation method called drip irrigation under brackish water film. However, brackish water brings salt into the soil while providing moisture to crops, causing different degrees of salinity stress to crops. T...

Problems solved by technology

Mechanical ventilation oxygenation is to use air compressor to aerate the irrigated soil, which has high energy consumption, high investment cost, and high equipment maintenance and maintenance costs in the later period; chemical oxygenation is to use chemical reagents such as hydrogen peroxide to add oxygen, often increasing the effect of oxygenation. It is not obvious, and it will cause certain pollution to water sources and soil; Venturi air jets have a simple structure, low cost, and wide application, but because they cannot change the dissolved oxygen capacity of brackish water itself, a large amount of dissolved oxygen is used in irrigation. During the process, it will be lost from the dripper or the ground part
