Description
Technical field
The utility model relates to atmospheric sampling technical field, relates in particular to a kind of hyperchannel air sampler that can Measurement accuracy gas flow.
Background technology
Along with the industrialized process of the mankind, environmental problem is day by day serious.The a large amount of discharging waste gas of commercial production, in air, harmful gas content constantly increases, and has brought serious harm to people's health.
Weather scientist and medical expert think, the haze weather being caused by fine particle is even larger than sandstorm to the harm of health.10 microns of above particles of particle diameter, can be blocked in outside people's nose; The particle of particle diameter between 2.5 microns to 10 microns, can enter the upper respiratory tract, but part can excrete by sputum etc., also can be stopped by the fine hair of nasal cavity inside in addition, relatively little to human health damage; And particle diameter is at the fine particle below 2.5 microns, diameter is equivalent to human hair's 1/10 size, is difficult for being blocked.After being inhaled into human body, can directly enter bronchus, disturb the gas exchange of lung, cause the disease that comprises the aspects such as asthma, bronchitis and cardiovascular disease.For this reason, must strengthen the monitoring of atmospheric environment and control.In order to realize atmospheric surveillance, need to carry out sample collection to perform an analysis to atmosphere, air sampler arises at the historic moment.Orthoscopic hyperchannel atmospheric sampling equipment major function is exactly accurately to realize the quantitative collection to surrounding air, for constituent analysis provides reliable sample.
When atmosphere is sampled, need to measure entering the endotracheal gas flow parameter of air sampler, such as to endotracheal gas flow measurement, with the most use is metal perforated plate flowmeter or orifice metre on the market, and it is widely used in each field that needs measurement of discharge.It is to utilize gas or liquid to produce differential pressure on the Shi both sides, aperture of flowing through, and square being directly proportional of this differential pressure and flow, utilizes this differential pressure to obtain flow.Yet, because of the differential pressure that orifice plate produces smaller, for can obtain large differential pressure with meet tonometric needs admittedly needs the bore of orifice plate is done little, and this makes foreign matter and dust easily in this accumulation, result in blockage and not detect flow.With orifice plate, measure when measuring the liquid that contains a small amount of solid or the gas that contains a small amount of liquid, middle nozzle easily stops up, and causes that measuring flow is inaccurate.
Therefore, need a kind of hyperchannel air sampler that can Measurement accuracy gas flow badly.
