Description
Technical field
The present invention relates to a kind of washing sterilizer of self-priming double-venturi structure and its applications, belong to harmful influence accident emergency
Toxic and harmful gas field is in particular to disposed using absorption process in disposal facility field.
Background technique
It in harmful influence leakage accident, usually exists simultaneously and endangers steam and leakage liquid, absorption process is mostly used to carry out it
Decontamination.In numerous washing equipments, Venturi scrubber has many advantages, such as that structure is simple, purification efficiency is high, easy to operate, in gas
Body absorbs and industrial dedusting field is used widely.
Venturi scrubber is generally divided into contraction section, throat and expanding reach, and liquid is by spraying into or passing through throat's gas
The negative-pressure ward of generation enters Venturi scrubber.Venturi scrubber currently used for decontamination toxic gas is mostly single venturi
Structure, there are liquid distribution unevenness, gas-liquid contact time section in expanding reach, injection volume is smaller the problems such as, be not able to satisfy high decontamination
The decontamination requirement of efficiency.The quantity for increasing Venturi tube structure can extend the decontamination time, strengthen gas-liquid contact, improve decontamination effect
Rate, therefore the decontamination ability of washer can be improved using the washer of double-venturi structure.Utility model patent CN
201529468 U propose a kind of combination type Venturi gas processing tower, pass through the arranged in parallel in gas treatment tower and are evenly distributed with
Several identical Venturi tubes are to solve the application problem of Venturi tube large-scale industrial production.The Venturi tube of laid out in parallel
Although the treating capacity of gas can be improved, total gas decontamination efficiency is identical as the decontamination efficiency in single Venturi tube, therefore
The detersive efficiency of gas treatment tower can not be improved.203315930 U of utility model patent CN proposes a kind of double-venturi punching
Formula desulfurizing dust-collector is hit, inside there are two Venturi tubes arranged side by side, expanding reach is connected with air inlet, and is equipped in expanding reach
Spray equipment, gas enter from expanding reach, enter in two Venturi tubes with ejecting liquid fair current and complete desulfurization and dedusting.This row
Although cloth structure improves the gas velocity in deduster, improve efficiency of dust collection, but throat easily blocks, and pressure needed for gas
Higher, operational stability is poor.
In conclusion, there is many lack in the washer development of double-venturi structure at present and immature, mostly laid out in parallel
Point, is not able to satisfy the requirement of toxic gas emergency washing and disin fecting, therefore the washing sterilizer for developing a kind of novel double-venturi structure is ten
Divide necessary.
Summary of the invention
The first technical problem to be solved by the present invention is that exist in the prior art arrangement mode single, is not able to satisfy toxic
Gas emergency washing and disin fecting, the low problem of detersive efficiency provide a kind of washing sterilizer of new self-priming double-venturi structure, have and deposit
In arrangement mode multiplicity, it is able to satisfy toxic gas emergency washing and disin fecting, the high advantage of detersive efficiency.Technology to be solved by this invention is asked
The two of topic are to provide a kind of washing sterilizer with corresponding self-priming double-venturi structure one of the technical issues of solution and answer
With.
One of in order to solve the above problem, The technical solution adopted by the invention is as follows: a kind of self-priming double-venturi structure
Washing sterilizer, including the import of gas straight tube, liquid annular entrance, venturi converging transition, venturi expanding reach, built-in venturi into
Liquid pipe and built-in venturi section composition, wherein liquid annular entrance is located above gas straight tube import, by after straight-run of pipe and
