Description
Technical field
The invention belongs to agricultural technology fields, and in particular to a kind of electrostatic atomizer and method based on induction charging.
Background technology
Electrostatic spray is to make the spray method that the droplet of ejection charges by high-voltage electrostatic generator, applies and is sprayed in pesticide
On mist, it is remarkably improved the effective rate of utilization of pesticide.The charging modes of droplet are divided into three kinds, i.e., corona charging, induction charging and
Contact is charged, and in three kinds of charging modes, contact charging effect is best, and induction charging takes second place, but is contacted charging and be relatively stranded because insulating
Difficult and seldom apply, induction charging is most widely used in practice.In induction charging, is formed near area in droplet, utilize electrode and medicine
Electric field between liquid jet stream makes droplet charge, and liquid can be grounded, and spray tank need not generally insulate, but electrode must and liquid
Insulation, induction charging voltage is relatively low, only needs several kilovolts, is suitable for conducting liquid.But current induction charging electrostatic atomiser
It has the following defects：Electrode setting nozzle periphery, spraying formed area distribution of charges have successively decrease from outer lateral center
The characteristics of, and spray and formed big with free surrounding space contact surface on the outside of area, higher charge gradient accelerates spraying and is formed outside area
The decaying of side distributed charge, affects spray effect.
Invention content
The technical purpose of the present invention is to provide a kind of novel electrostatic atomizer and method, to overcome the prior art not
Foot, technical solution are：
A kind of electrostatic atomizer based on induction charging, the electrode for being equipped with nozzle and being connect with electrostatic generator are special
Sign is that there are the nozzle more than two spouts, the spout to be symmetricly set on electrode both sides or the shape with annular array
Formula is distributed in around electrode.
On the basis of said program, it is further improved or preferred mode further includes：
Preferably, the electrode is plate electrode, the spout is the spout with fan-spray form, two spouts pair
Claim setting in electrode both sides, electrode plate body is clipped in two spouts spraying form area between, and spray covering of the fan and electrode plate body
Plate face is unfolded in the same direction.
The nozzle includes sprinkler cap, nozzle boss and connector, and the sprinkler cap is connected mounted on nozzle boss, the spray
Headstock is connect by connector with infusion pipeline, and the spout is in processing formation on sprinkler cap, the electrode setting is in the spray
On head cap.
A kind of electrostatic spraying method based on induction charging, which is characterized in that more than two spouts, choosing are arranged to nozzle
The electrode for selecting the Sprayable external shape fits having with spout, by electrode arrangement in the centre position of each spout, each spout is symmetrical
Be distributed in electrode both sides or it is arranged in a ring be evenly distributed on surrounding them, so that nozzle is integrally sprayed and form area's middle part bit distribution
Charge inducing increase, outside distribution charge inducing reduced relative to intermediate position, make the charge gradient phase between free surrounding space
The protective layer that area's outside left forms the larger intermediate position of charge gradient is formed to smaller spraying, it is quiet that reduction spraying forms area
The decaying of charge.
Preferably, it is the spout with fan-spray form, institute that the electrode, which uses plate electrode, the notch setting,
The plate body for stating electrode is clipped in the sprayings of two spouts and is formed between area.
Advantageous effect：
Electrostatic atomizer of the present invention and method, reasonable design, it is easy to accomplish, spraying droplet induced electricity can be effectively reduced
The decaying of lotus significantly improves electrostatic spray effect, and position between electrode setting in the showerhead, improves the safety used.
Description of the drawings
Fig. 1 is the main structure diagram of one embodiment of the invention.
Fig. 2 is the side structure schematic view of Fig. 1 embodiments.
Specific implementation mode
In order to clarify the technical solutions and technical objectives of the present invention, below in conjunction with the accompanying drawings and specific embodiment is the present invention
It is further to introduce.
A kind of electrostatic spraying method based on induction charging, can be used for the improvement to existing spray technique, and process is as follows：
According to the preset flow of nozzle, more than two spouts are arranged to nozzle, and select the spraying shape having with spout
