's.Meanwhile, swirl vane it is simple in construction.
In the present embodiment, circumferentially direction is evenly arranged on the inwall of venturi enlarged tube 4 swirl vane 51.
In order to further enhance the rotary speed and less turbulence of gas-liquid flow, can circumferentially direction in venturi enlarged tube
More than one layer swirl vane 51 is evenly arranged on 4 inwalls.
In the present embodiment, swirl vane 51 can also be selected twist to be arranged on the inwall of venturi enlarged tube 4.
In the present embodiment, in addition to feed tube 6.Feed tube 6 is sheathed on air inlet pipe 1 and the periphery of venturi collapsible tube 3.Feed liquor
Pipe 6 is connected with venturi enlarged tube 4.Inlet 2 is arranged in the inwall of feed tube 6 and air inlet pipe 1 and the outer wall of venturi collapsible tube 3
Between.
In the present embodiment, feed tube 6 includes portion respectively with air inlet pipe 1 and the formation form fit of venturi collapsible tube 3
Point.
Because feed tube has the part that the shape with venturi collapsible tube is worked in coordination, decontamination solution is received by this feed tube
When contracting section enters inlet, the flowing velocity of decontamination solution can also be increased, so as to increase decontamination solution and the gas of entrainment leak liquid
Stream is strong to be mixed, and increases decontamination efficiency.
In the present embodiment, air inlet pipe 1, feed tube 6, venturi collapsible tube 3 and venturi enlarged tube 4 are revolving body.
Above-mentioned each body is easy to processing using rotary structure.
In the present embodiment, air inlet pipe 1, venturi collapsible tube 3, venturi enlarged tube 4, eddy flow generation device 5 and feed tube 6
Including metal level.
The reliability and service life of venturi washing sterilizer can be improved using metal material.
In the present embodiment, air inlet pipe 1, venturi collapsible tube 3, venturi enlarged tube 4, eddy flow generation device 5 and feed tube 6
Including perspex layer.
Mitigate the weight of washing sterilizer on the premise of may insure washing sterilizer mechanical strength using lucite material, together
When lucite material be also easy to processing.
The venturi washing sterilizer specific work process that the utility model is related to is as follows：
In the presence of blower fan, harmful influence waste gas entrained leakage liquid is in the way of negative-pressure ward or malleation air blowing by air inlet
The entrance of pipe 1 enters venturi collapsible tube 3.Because venturi collapsible tube 3 is pyramidal structure, flow section is gradually reduced, in folder
In the case of gas flow rate constant with leakage liquid, the gas velocity of entrained leakage liquid increases, in venturi washing sterilizer 7
Static pressure reduces, and there is pressure difference with external pressure.Decontamination solution enters venturi collapsible tube in the presence of pressure difference by inlet 2
3 and the junction of venturi enlarged tube 4 contacted with the gas of entrained leakage liquid.Due to the gas velocity of entrained leakage liquid
Very fast, decontamination solution and leak liquid are atomized as fine droplet, and now gas is continuous phase, and liquid is dispersed phase.
Wherein directly expand because the venturi washing sterilizer in the present embodiment employs venturi collapsible tube with venturi
The structure of pipe connection, so that the gas for reducing entrained leakage liquid loses from what venturi collapsible tube flowed out along stroke pressure.Phase
The structure connected again with venturi enlarged tube after being connected to use venturi collapsible tube in the prior art with Venturi throat is more
It is simple and improve decontamination efficiency.
Afterwards, the fine droplet after gas entrainment atomization continues to ascend into venturi enlarged tube 4, in inwall swirl vane
It is changed into rotation from original vertical ascent in the presence of 51 to rise, the tangential velocity of gas-liquid flow is increased, while avoiding gas
The adherent effect of liquid stream, enhances contact of the gas phase with liquid phase, and swirl vane adds liquid phase in venturi enlarged tube
Interior residence time, and to fluid cut further increase gas-liquid flow turbulence, reinforcing decontamination solution and harmful influence steam and let out
The contact of leakage body, and then add decontamination efficiency of the decontamination solution to harmful influence steam and gas leakage.
Expand because swirl-flow devices are arranged in venturi on inside pipe wall, inlet is arranged in Venturi tube inlet and is arranged in
Venturi collapsible tube and venturi enlarged tube junction, so can avoid swirl-flow devices excessive and easy by the impulsive force of fluid
Come off.
Finally, gas-liquid mixture is discharged in the outlet of venturi enlarged tube 4.
Although the utility model is described by reference to preferred embodiment, the utility model scope is not being departed from
In the case of, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as being not present
The every technical characteristic being previously mentioned in structural hazard, each embodiment can combine in any way.The utility model is simultaneously
It is not limited to specific embodiment disclosed herein, but all technical schemes including falling within the scope of the claims.
