Embodiment Construction

[0019] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] In the micro-irrigation emitter and its production method provided by the embodiments of the present invention, nano-titanium dioxide is sprayed on the surface of the finished spray irrigation emitter or the nano-titanium dioxide and production raw materials are mixed in a certain proportion to directly produce a micro-irrigation emitter product. Since the photocatalyst is only used as a catalyst to promote the oxidation-reduction reaction, it does not participate in the chemical reaction itself, and the substance itself is not lost during the catalytic process. Theoretically, as long as the nano-titanium dioxide coating or material is not damaged, it can exert redox activity for a long time, and use ...

Abstract

The invention discloses a micro-irrigation emitter, which comprises a water dropper, a spray-head and a drop-irrigation pipe (strip). The inner wall and / or the outer surface and / or a water outlet part of the micro-irrigation emitter are / is covered with a photocatalyst film coating layer. The micro-irrigation emitter of the invention has the advantages of: 1) a sterilizing function, namely, nano-TiO2 can damage cell membranes of cells because of super-oxidation decomposition capacity to cause cytoplasm loss to further cause the death of bacteria, which can prevent the occurrence of biological clogging; 2) a water purification function, namely, the micro-irrigation emitter has the function of eliminating water pollution and removing organic harmful substances in water so as to avoid chemical jamming; 3) a self-cleaning function, namely, the nano-TiO2 has extremely strong hydrophilicity so as to effectively prevent dust from being absorbed and staying to further realize the self-cleaning function and relieve physical jamming; and 4) an anti-aging function, namely, the nano-TiO2 needs to absorb a great amount of ultraviolet light to produce a light-catalyzed reaction, so the micro-irrigation emitter has relatively stronger functions of absorption, reflection, scattering and the like on the ultraviolet light and has weatherability and ageing resistance.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a micro-irrigation dispenser. Background technique [0002] Micro irrigation, according to the needs of the crops, through the pipeline system and the irrigator installed on the final pipeline, the water and the nutrients required for crop growth are directly delivered to the roots of the crops evenly and accurately at a small flow rate. A method of watering nearby soil. Compared with traditional surface irrigation, micro-irrigation only moistens part of the soil near the root zone of crops with a small flow rate, which belongs to local irrigation technology. Blockage of micro-irrigation system is a common phenomenon in the operation of micro-irrigation system, and it is also the main obstacle affecting the popularization and application of micro-irrigation technology. [0003] The reasons for the clogging of micro-irrigation emitters mainly include three major ...
