Anti-biological clogging device for drip-irrigation system

Abstract

The invention relates to an anti-biological clogging device for a drip-irrigation system. The drip-irrigation system is started, an air intake brake valve is opened, an ozone generator is started, and compressed water which comes from the head part of the drip-irrigation system is sprayed at high speed from a jet orifice of a jet nozzle so as to form the negative pressure in a gas injection cavity; and under the action of the negative pressure, the ozone generator ensures that ozone generated through air ionization enters the gas injection cavity through the air intake brake valve, a check valve and an air inlet pipe along with the air filtered by an air filter, and enters an oscillating cavity for vortex oscillation, stirring and aerification along with the high-speed water flow sprayed by the jet nozzle so as to form 'ozone water' of which gas and liquid are distributed uniformly, and the 'ozone water' enters the drip-irrigation system to kill microorganisms in flow channels and cansynchronously inhibit crop root systems from growing toward the direction of a water outlet of a drip irrigation emitter in an underground drip-irrigation system, so that the aim of biological clogging resistance of the drip-irrigation system is fulfilled. Compared with a method of injecting a chemical agent into irrigation water, the invention has the advantages that: the residue of harmful substances which can pollute the environment is not produced, and the risk of using dangerous chemical agents is avoided.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and in particular relates to an anti-biological clogging device for a drip irrigation system. Background technique: [0002] Drip irrigation is a kind of local irrigation, which consists of five parts: the first hub, the main pipe, the branch pipe, the capillary pipe, and the sprinkler. ①The head hub is responsible for water intake, pressurization and water treatment, and is composed of water pumps, fertilizer tanks, filters, pressure gauges, flow meters and other components; ②The main pipe plays the role of water delivery; Crop water demand, distribute irrigation water to the irrigation area; ④ Capillary pipes are connected with branch pipes to send water to the roots of crops; ⑤ Irrigators, including: drippers, water outlets, etc., have different types and shapes to Moisten the soil at the root of the crop. Arranging drip irrigation capillaries and emitters under...

Problems solved by technology

However, the sterilizing function of the technical solutions of the above two patents is only limited to the emitter. The biological matter that grows and reproduces in the water delivery pipeline before the emitter of the drip irrigation system and behind the head hub filter can still cause blockage of the emitter. Anti-bioclogging effect and durability are still not guaranteed

In addition, photocatalyst substances, as the name suggests, need to be stimulated by light to produce bactericidal activity, which is obviously not suitable for underground drip irrigation systems

The biological clogging of the drip irrigation system has seriously affected the irrigation efficiency and quality of the drip irrigation, which has limited the popularization and application of the drip irrigation technology, especially the underground drip irrigation technology. There is an urgent need for better anti-biological clogging methods and devices for the drip irrigation system.
