Description
Technical field
The utility model relates to ambient air monitoring technical field, is specifically related to a kind of Atmospheric particulates cyclone type sampling thief of low discharge.
Background technology
The severe haze of wreaking havoc the second half year in 2013 whole nation makes air quality become the topic in everybody streets and lanes at ordinary times, has also urged some neologisms of heat, such as PM
2.5(PM
2.5refer to that in surrounding air, aerodynamics equivalent diameter is less than or equal to the particle of 2.5 μm, also claims fine particle).Fine pollutant in air is air-polluting main source, the suspended particulate substance that in air, aerodynamics equivalent diameter is less than 10 μm is defined as sucking suspended particulate substance, they can be collected at lung, harm humans is healthy, and the fine particle that wherein equivalent diameter is less than 2.5 μm directly can enter human body alveolar, therefore also maximum to human health damage.
Along with people pay attention to for improvement air-polluting further for the common concern of air quality and government, the strict discharge controlling air pollution source becomes the important handgrip that air quality is set about improving by environmental administration.Therefore, environmental administration is in the urgent need to effectively polluting the equipment of unit, place air quality by Real-Time Monitoring emphasis.And the mode that on market, existing sample devices adopts filter membrane or micro-strainer to trap bulky grain thing is mostly sampled and the method for air quality monitoring function, shortcoming is obvious.The first, can not work incessantly for a long time, frequency of maintenance is frequent, needs manually to pull down for every 1 ~ 2 month and manual cleaning; The second, volume large (long 200mm, more than diameter 100mm), sampling flow large (more than 16L/min), cause that dust stratification is serious, noise and energy consumption all excessive.And the technology that the utility model adopts can overcome these shortcomings.
Summary of the invention
The purpose of this utility model, it is the Atmospheric particulates cyclone type sampling thief in order to provide a kind of low discharge (about 2 ~ 5L/min), this sampling thief is separated the gas obtaining the fine particle being less than or equal to required PM value containing equivalent diameter under different inlet air flow velocity with the effect of gravity by centrifugal force, thus realize the sampling of gas; When cleaning is needed, automatically open solenoid valve and the particle that deposit in ash bucket is discharged sampling thief, thus realize the automatically cleaning of sampling thief by control system, really like this accomplish unmanned, manpower-free safeguards.
Above-mentioned the purpose of this utility model realized by following technical scheme:
The utility model provides a kind of Atmospheric particulates cyclone type sampling thief of low discharge, consists predominantly of: speed governing air pump, miniature whirlwind cutter, ash bucket, solenoid valve and control system.Miniature whirlwind cutter bottom ash hole and ash bucket by thread connection, and realize the air seal of screw thread place by seal approach; Ash bucket bottom is connected with a solenoid valve by screw thread, and screw thread place also takes air seal measure, and solenoid valve is closed type, and the open and close of solenoid valve is controlled by control system.
Cyclone type sampling thief as above, there is a gas feed side of miniature whirlwind cutter, and there is a gas vent on top; Gas feed is connected with surrounding air by a tracheae; Head gas outlet is connected with speed governing air pump by a tracheae, and the outlet side of speed governing air pump is sample gas; Speed governing air pump controls cutter gas inlet velocity by control system.After gas enters miniature whirlwind cutter, air-flow becomes circular motion from rectilinear motion, under the effect of centrifugal force, gravity and viscous resistance etc., large-size particles thing settles down, small size particle is discharged with sample gas through gas vent, within the scope of certain inlet velocity, inlet gas velocity is higher, and separable minimum grain size is less.
Cyclone type sampling thief as above, need the inlet flow rate recording the corresponding miniature whirlwind cutter of required PM value in advance by experiment, like this when using this sampling thief to carry out particle sampling, just can carry out the gas sampling of particulate in air according to the inlet flow rate value of PM value correspondence.
By above technical scheme, the utility model has the advantage of:
The speed governing air pump of cyclone type sampling thief is controlled by control system, effectively can control the gas flow entering miniature whirlwind cutter, the separable particle minimum diameter of miniature like this whirlwind cutter also changes thereupon, thus obtain the sample gas of required PM value, and then realize the target of " sampling thief provides multiple sample gas ".In addition, when needs are clean, solenoid valve is opened by control system automatically, and the particle deposited in ash bucket discharges miniature whirlwind cutter automatically, thus realizes the self-cleaning effect of cutter.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present utility model.
Critical piece label declaration:
Embodiment
For making goal of the invention of the present utility model, technological means and technique effect have more complete and clearly disclose, below will describe in detail, and seeing also accompanying drawing and part numbers.
The utility model provides a kind of Atmospheric particulates cyclone type sampling thief of low discharge, refers to shown in Fig. 1, consists predominantly of miniature whirlwind cutter 2, speed governing air pump 7, ash bucket 5, solenoid valve 1, control system 6.
Wherein, this cyclone type sampling thief is provided with a miniature whirlwind cutter 2, and there is a gas feed 3 this cutter 2 side, and there is a gas vent 4 on top, and an ash hole 10 is arranged at bottom; Cutter side import 3 is directly connected to surrounding air by tracheae 9; Ash hole place, cutter bottom 10 is by thread connection ash bucket 5, and screw thread place adopts sealant tape or parcel raw material band to seal; Gas outlet, top 4 is connected with speed governing air pump air intake opening 11 by tracheae 9; Speed governing air pump outlet 8 is sample gas.
Ash bucket 5 bottom is connected with a solenoid valve 1 by screw thread, and screw thread place adopts sealant tape or parcel raw material band to seal, and solenoid valve 1 is closed type, and the folding of solenoid valve 1 is controlled by control system 6; Speed governing air pump 7 changes flow by control system 6, the object controlling miniature whirlwind cutter air intake opening 3 flow can be reached like this, after cutter air intake opening 3 flow changes, the centrifugal force of particulate in air suffered by miniature whirlwind cutter 2 also can change, the separable smallest particles diameter of such vortex cutter 2 also changes thereupon, thus realizes the gas sampling of different PM value.
Above act is only the schematic section Example of the utility model; and be not used to limit scope of the present utility model; any those skilled in the art; equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should be included within this patent protection domain.
