Description
Technical field
The present invention relates to a kind of drip emitter and method for using thereof that is used for the water-saving irrigation field, particularly about a kind of stacked self adaptation drip irrigation pipe (band) douche and method for using thereof.
Background technology
Drip irrigation is considered to the most safe and reliable irrigation method in the modern irrigation method because of its smart amount, controlled characteristics; Yet contain materials such as a large amount of particles, nutrient salt, organic matter, microorganism in the natural water, make the douche blockage problem become more complicated.Douche is the parts of drip irrigation system most critical, and its effect is after making pressure water stream through its inner long and narrow runner or the abundant energy dissipating of micropore, to splash into soil with even, stable low discharge.But also just because of the needs of douche energy dissipating; Channel size generally has only about 0.5～1.2mm; Impurity such as the suspension in the water, dissolving salt, chemical precipitation, microorganism all very easily cause the obstruction of douche; The douche blockage problem has become the major obstacle that the restriction drip irrigation technique is used, promoted, and the quality that it solves is directly determining the service life and the application benefit of engineering.
It also is to cause the whole system uneven main cause of pouring water that douche stops up, even limited several douches stop up the uniformity that also can reduce douches greatly.Since Israel held, a large amount of scientific research persons attempted to solve from the many-sides such as processing of reasonable disposition filter plant, periodicity acid and chlorine the problem of system jams, has obtained some more significant achievements from first international drip irrigation meeting in 1971.Chinese scholar also solves the douche blockage problem from douche structural design angle and has carried out some explorations: disclose a kind of flow passage structure design method for anti-blocking turbulant irrigator like (publication number CN1636437A) such as the Fan Xingke of Xibei Univ. of Agricultural & Forest Science & Technology; Adopt arc-shaped curved surface to avoid the deposition of fine particle based on erratic flow in the hydraulics and vortex theory to runner cell side face, but prevent that for what biology stopped up effect is not remarkable with eddy current curved surface features.Yang Peiling etc. (publication number CN1454459) disclose a kind of drip emitter, adopt the form of fractal runner to strengthen effect of energy dissipation, but performance of anti-blockage are relatively poor.Also have the part scholar to invent Antiplugging drip irrigation irrigator, for example Dai Baixin etc. (publication number: CN101244407A) disclose a kind of anti-blocking dropping head, can realize pressure compensation, but owing to there is not the energy-dissipating structure unit through the pressure mouth, effect of energy dissipation a little less than.
In general; Relevant research at present also mainly concentrates on douche anti-block designing method aspect; The anti-obstruction douche product function of exploitation is single; The anti-obstruction of the real meaning that also is unrealized relies on the product of the adaptive ability lifting douche performance of anti-blockage of douche itself also not appear in the newspapers.Therefore, rely on the adaptive ability of douche, develop the good and multi-functional drip emitter new product of a kind of waterpower and performance of anti-blockage, become the task of top priority of modern agriculture production development.
