Abstract
The invention relates to an aerosol generator which comprises a shell body, an air inlet and an air outlet are formed in the shell body which is internally provided with a Laskin nozzle, the Laskin nozzle is connected with the air inlet through a pipeline, compressed air is fed into the air inlet, an air outlet nozzle is arranged on the air outlet, and the air outlet nozzle is fixed on the upper portion of the side wall and inclines upwards. Accordingly, by means of the inclined air outlet nozzle, water drops can be formed by fogdrop retained inside and flow back to the inside of the shell body, follow-up spraying is facilitated, backflow can not be blocked, the structure is simple, and use is convenient.
Description
Technical field
The present invention relates to measuring for materials field, especially relate to a kind of aerosol generator for material tests.
Background technology
At present, detection and filter leak many employings air of filtrate, finished product filter are dirt source, and due to the difference in geographic position, the concentration of atmospheric dust and particle diameter can change, and can cause the uncertainty of filtrate test structure and the nonrepeatability of test; In detecting filtrate, in order to reduce the error in testing efficiency of air filter, atmospheric dust is replaced to be very important as test dirt source with the artificial colloidal sol that domain size distribution is determined.Its principle of work of aerosol generator is that pressurized air or oxygen (driving force) pass through thin mouth nozzle with high velocity air, according to Venturi effect, around nozzle, produce negative pressure carry receiver liquid and involve in high velocity air and be ground into droplet not of uniform size, wherein more than 99% be oarse-grained droplet composition, collide tiny droplet remaining in the receiver that falls back with ejection at a high speed by the interception of nozzle, hit the particle fallen and be again atomized.
Its outgassing nozzle of existing aerosol generator normally side install and horizontal, oarse-grained droplet can be trapped in nozzle pipe after being tackled by nozzle, ejection and the backflow of subsequent spray will be affected like this, thus cause the uncertainty of spraying granule and speed, affect Detection results.
Summary of the invention
Technical matters to be solved by this invention is to provide its colloidal sol generator that a kind of droplet be blocked realizes backflow rapidly.
The present invention solves the technical scheme that its technical matters takes: a kind of aerosol generator, comprise shell body, described shell body is provided with air intake opening and gas outlet, Laskin nozzle is provided with in described shell body inside, described Laskin nozzle is connected with air intake opening by pipeline, described air intake opening passes into pressurized air, and described gas outlet place is provided with outgassing nozzle, and described outgassing nozzle is fixed on the top of sidewall and is inclined upwardly.
Concrete further, the inside of described shell body is provided with level sensor, described shell body is provided with control chip and is connected with level sensor, described shell body is provided with liquid-adding device and is connected with control chip.
Concrete further, described liquid-adding device comprises solution reservoir, and described solution reservoir is provided with water pump, and solution is delivered in shell body by described water pump.
Concrete further, the acclivitous angle of described outgassing nozzle is 30 °.
The invention has the beneficial effects as follows: after have employed said structure, by the outgassing nozzle tilted, shell body inside can be back to rapidly by being trapped in after inner droplet is combined into water droplet, facilitate follow-up ejection and backflow to be obstructed, structure is simple, easy to use.

Embodiment
Below in conjunction with accompanying drawing, the present invention is explained in detail.
A kind of aerosol generator as shown in Figure 1, comprise shell body 1, described shell body 1 is provided with air intake opening 2 and gas outlet 3, Laskin nozzle 6 is provided with in described shell body 1 inside, described Laskin nozzle 6 is connected with air intake opening 2 by pipeline, described air intake opening 2 passes into pressurized air 4, and described gas outlet 3 place is provided with outgassing nozzle 7, and described outgassing nozzle 7 is fixed on the top of sidewall and is inclined upwardly; The inside of described shell body 1 is provided with level sensor 8, described shell body 1 is provided with control chip 9 and is connected with level sensor 8, described shell body 1 is provided with liquid-adding device 5 and is connected with control chip 9; Described liquid-adding device 5 comprises solution reservoir, and described solution reservoir is provided with water pump, and solution is delivered in shell body 1 by described water pump; The described acclivitous angle of outgassing nozzle 7 is 30 °.
When using, the nozzle tilted makes droplet reflux rapidly, the liquid level of level sensor 8 pairs of shell body 1 inside is responded to, when sensing that liquid level is not enough, control liquid feeding in shell body 1, after being added to correct position by control chip 9 pairs of liquid-adding devices 5, control chip 9 controls liquid-adding device 5 and quits work, complete intelligent filling operation, structure is simple, easy to use.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
