Abstract
The utility model relates to an aerosol generator, which comprises an air inlet control device, a compressed air generation device, and an aerosol generation device. The air inlet control device is used for controlling the pressure and inflow of compressed air and is connected with a gas generation device and the aerosol generation device. The air inlet control device comprises a change-over valve, an adjusting valve, a pressure regulating valve, and a compressed air intake. The compressed air generation device comprises an air pump, a filter, and an air pump adjusting button for adjusting the air pump. The gas generation device comprises a container, a spraying port, a liquid level pipe arranged on the side wall of the container and a plurality of Laskin spray nozzles arranged in the container. The generator can supply a stable gas source, so that the detection of filter mediums and finished filters and the leak detection of filters are more accurate.
Description
[technical field]
The utility model relates to a kind of aerosol generator, is specifically related to a kind of the leak detection for filtrate, filter the aerosol generating device of stablizing source of the gas and being used for demarcation of particle detection quasi-instrument and test is provided.
[background technology]
At present, it is the dirt source that the detection of domestic filtrate, finished product filter and filter leak adopt atmosphere more, its advantage is convenient, but big air exhaustion instability, important parameters such as the concentration of atmospheric dust and particle diameter distribution change whenever and wherever possible, cause testing efficiency of air filter result's the uncertainty and the nonrepeatability of test.And the Atmospheric composition of various places is all inequality, causes net effect all bad, has greatly hindered the development of China's filter.In testing efficiency of air filter, in order to reduce the error in the testing efficiency of air filter, the artificial colloidal sol of determining with the particle diameter distribution replaces atmospheric dust to be very important as test dirt source.
In the efficiency test of air cleaner,, compare with atmosphere as test dirt source with artificial aerosol, the dirt source stability is good, and particle decentralization and concentration are easy to control, test result accuracy height, good reproducibility.Replace atmospheric dust more reliable with artificial aerosol, can satisfy the requirements at the higher level that filter industry proposes testing as the efficient testing result of test dirt source test air cleaner.At present, the test dirt source of American-European countries's testing efficiency of air filter is artificial aerosol.
General aerosol generator comprises that is used to make the pipeline that is heated that evaporates.For example the United States Patent (USP) patent No. 5743251, and it discloses a kind of aerosol generator, comprise that the heater of a pipeline and an operability volatilizees liquid pipeline is heated to sufficiently high temperature in pipeline.The material of volatilization goes out from the pipe end expansion and mixes with surrounding air, thereby forms the aerosol of condensation.Its structure is also comparatively complicated.
[utility model content]
In order to solve the above-mentioned deficiency of prior art, the utility model purpose is to provide a kind of aerosol generator.
For achieving the above object, one of the utility model embodiment provides a kind of aerosol generator, comprising: an Intaker controller, a compressed air generation device, and an aerosol generating device.Described inlet duct is controlled compressed-air actuated pressure and air inflow, and connects gas generation apparatus and aerosol generating device.Described Intaker controller comprises a switching valve, a control valve, a pressure regulator valve and a compressed air inlet port.Described compressed air generation device comprises an air pump, and a filter and is regulated the air pump adjusting knob of air pump.Described gas generating unit comprises a container, and a nozzle, a liquid level tube are located at container side wall and some Laskin nozzles are located in the container.
Design based on the foregoing description, advantage of the present utility model is: this aerosol generator is comprehensive, can provide stable source of the gas for the detection and the filter leak of filtrate, finished product filter, and aerocolloidal refractive index is close with atmosphere, makes the detection effect more accurate.
Other purposes of the present utility model and advantage can be further understood from the disclosed technical characterictic of the utility model.State with other purposes, feature and advantage and can become apparent on the utility model for allowing, embodiment cited below particularly also cooperates appended graphicly, is described in detail below.

[specific embodiment]
About addressing other technologies content, characteristics and effect before the utility model, in the following detailed description that cooperates with reference to graphic embodiment, can clearly present.The direction term of being mentioned in following examples, for example: upper and lower, left and right, front or rear etc. only are the directions with reference to annexed drawings.Therefore, the direction term of use is to be used for illustrating not to be to be used for limiting the utility model.
Please refer to Fig. 1, a kind of aerosol generator of an embodiment of the present utility model comprises: an Intaker controller, a compressed air generation device, and an aerosol generating device.Described inlet duct is controlled compressed-air actuated pressure and air inflow, and connects gas generation apparatus and aerosol generating device.Described Intaker controller comprises switching valve 1, one control valve, 2, one pressure regulator valves 3 and a compressed air inlet port 4.Described compressed air generation device comprises the air pump adjusting knob 8 of an air pump 10, one filters 9 and an adjusting air pump.Described gas generating unit comprises that a container 11, one nozzles 5, one liquid level tubes 7 are located at container 11 sidewalls and some Laskin nozzles 6 are located in the container 11.Because this aerosol generating device internal pump 10 just needs external compressed air so have only when aerosol concentration is not enough.Ordinary circumstance can be controlled the Compressed Gas that reaches Laskin nozzle 6 by filter 9 by air pump adjusting knob 8 control air pumps 8.Compressed Gas produces aerosol behind Laskin nozzle 6, aerosol is atomized the back by baffle plate, and big particle is blocked, and little particle enters required equipment by nozzle 5.This aerosol generator is comprehensive, can provide stable source of the gas for the detection and the filter leak of filtrate, finished product filter, and the aerocolloidal refractive index and the atmosphere that are produced is close, makes the detection effect more accurate.
Though the utility model discloses as above with preferred embodiment; so it is not to be used for limiting the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; when can doing a little change, so the protection domain of the utility model is as the criterion when looking the patent protection scope person of defining.In addition, arbitrary embodiment of the present utility model or claim must not reached whole purposes or advantage or the characteristics that the utility model discloses.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the rights protection scope that is used for limiting the utility model.
