The problem of existing process chamber is present mainly has：(1) fast among flow velocity in process chamber, border is slow, causes flow velocity uneven
Even, partial material, which is detained, causes processing incomplete, and as inlet flow rate and chamber size increase, in exit electrodes
Fluid velocity inhomogeneities aggravation；(2) electric-field intensity distribution is unreasonable, and nearby electric-field intensity skyrockets electrode, spike electricity be present
, and the local too high possible guiding discharge problem of electric field；(3) bactericidal effect of single processing chamber is limited, and treating capacity
Restricted by physical dimension.
From the prior art, most of design of process chamber is confined to laboratory scale at present, from the processing of commercialization
It is required that larger gap be present.In order to improve the coupling field characteristic of process chamber, the middle promulgated by the State Council of Patent No. 201110359035.0
Bright patent discloses a kind of common field process chamber of the high-pressure pulse electric sterilization system based on coupled field structure optimization, and it is improved
In employing oval embedded field process chamber configurations altogether, preferable electric field, Flow and heat flux are obtained in material processing region
Characteristic, but in multiprocessing chamber unit tandem compound in use, with the raising of material inlet flow velocity or the increasing of chamber size
Greatly, the material lagging region of larger area is still had at the material outlet of each processing chamber unit, forms whole fluid system
The uneven phenomenon of the velocity flow profile of system, is unfavorable for commercial applications.
Utility model content
The utility model aims to overcome that above shortcomings in the prior art, there is provided one kind is excellent based on fluid behaviour
The common field process chamber of the high-pressure pulse electric sterilization system of change.
The technical scheme steps that the utility model is taken are as follows：
It is a kind of based on fluid behaviour optimization high-pressure pulse electric sterilization system common field process chamber by charging aperture conduit, go out
Material mouth conduit, metal hollow tubulose high-field electrode, insulator isolated tube, metal hollow tubular grounding electrode, sealing nut, cutting ferrule
And sealing ring composition, insulator isolated tube are located between metal hollow tubulose high-field electrode and metal hollow tubular grounding electrode
Form process chamber.
Metal hollow tubulose high-field electrode and metal hollow tubular grounding electrode interior cavity are respectively provided with certain taper, several
What is shaped as round table-like, taper >=7 of this round table-like cavity:100, the less end face in both apertures isolates with insulator respectively
It is close to the hole both sides of pipe.All electrode and insulator isolated tubes are sealed using threaded connection by sealing ring, prevent liquid
Body leaks.
The big end internal diameter of the round table-like cavity of metal hollow tubulose high-field electrode and metal hollow tubular grounding electrode is 2mm
~14mm, the long axis length and this distance of the ellipticity projection of insulator isolated tube are close or equal.
Compared with prior art, advantage is the utility model：It is described altogether field sterilization processing room in tandem compound in use,
Preferable fluid behaviour can be obtained, is solved in ordinary electrode inner chamber as inlet flow rate or chamber size increase and cause
The problem of exit velocity flow profile is uneven, it is incomplete existing to avoid the processing that material lagging in the case of larger process amount is brought
As.The distribution of process chamber electric field intensity inside high is also relatively reasonable, can obtain preferable sterilization processing efficiency.Therefore, the process chamber can
To meet the application requirement of Commercial scale, have the advantages that function admirable, it is compact-sized, be applied in combination convenient, be high-voltage pulse
The commercial applications of electric-field sterilizing provide possibility.
