Embodiment 1

[0031] This embodiment provides a capillary air-water combined flushing system for direct drip irrigation of high-sand content water, such as Figure 1 to Figure 3 As shown, it includes a water pump 1, and the water pump 1 is connected to the water distribution pipe 3-2 of the drip irrigation belt 3 through the water delivery pipeline 2. The drip irrigation belt 3 includes a plurality of drip irrigation capillaries 3-1, and the plurality of drip irrigation capillaries 3-1 The head end of 1 is connected by water distribution pipe 3-2, and the tail ends of multiple drip irrigation capillary pipes 3-1 are connected by flushing and mud discharge pipe 3-3;

[0032] The water pipeline 2 between the water pump 1 and the water distribution pipe 3-2 communicates with the air compressor 5 through the gas pipeline 4 with the first valve 7;

[0033] A gas-water turbulent mixer 6 is connected in parallel on the water pipeline 2 between the gas pipeline 4 and the water distribution pipe 3-2...

Embodiment 2

[0047] This embodiment provides a capillary air-water flushing method for direct drip irrigation of high-sand content water, the method adopts the capillary air-water flushing system for direct drip irrigation of high-sand content water as described in Example 1, wherein : the pressure in the air pipeline (4) is greater than the pressure in the water pipeline (2) during the air-water combined flushing process.

[0048] During the implementation of the above-mentioned flushing process, three specific parameters need to be controlled: the flushing time T of the system, the gas pressure P during the flushing process, and the flushing water head H. A complete flushing process of the drip irrigation system combined with air and water is completed.

Abstract

The invention provides an air-water combined flushing system and method for a high-sand-laden water direct drip irrigation capillary tube. According to the air-water combined flushing system, a water pipeline arranged between a water pump and a water distributing pipeline communicates with an air compressor through an air pipeline provided with a first valve; an air-water turbulent mixer parallelly communicates a water pipeline arranged between the air pipeline and the water distributing pipeline; a second valve and a third valve are mounted at two ends of the air-water turbulent mixer; and a fourth valve and a fifth valve are mounted on the water pipeline which parallelly communicates with the air-water turbulent mixer. The air-water combined flushing system provided by the invention combines water flushing and air flushing, thereby reducing the waste of water resources and ensuring a water flushing effect on the tail end of the drip irrigation capillary tube. High-pressure air and high-velocity water flow are subjected to turbulent mixing in the air-water turbulent mixer, so that condensed sediment particles which are deposited on the bottom of the drip irrigation capillary tube can be impacted and sufficiently mixed with air-water mixed flow.

Description

technical field [0001] The invention belongs to the field of drip irrigation and relates to a drip irrigation system, in particular to a capillary air-water combined flushing system and method for direct drip irrigation of high-sand content water. Background technique [0002] my country is a country seriously short of available water resources. Although the total reserves of water resources are very rich, the per capita water resources are only a quarter of the world's average level. At the same time, there are still prominent problems of low water resource utilization efficiency and serious waste in the field of agricultural water resource utilization in my country. Based on the above-mentioned current situation of my country's water resources and the existing problems in the field of agricultural water resource utilization, it is imperative to promote the development of efficient water-saving agricultural irrigation methods and improve the utilization rate of agricultural...
