Description
Technical field
The present invention relates to a kind of gas diffusion capturing device, particularly relate to a kind of rotary gas and spread continuous capturing device.
Background technology
Atmospheric water dissolubility gaseous contaminant mainly comprises gaseous ammonia (NH
3), sulphuric dioxide (SO
2), gaseous state nitric acid (HNO
3), gaseous state nitrous acid (HNO
2), gaseous hydrochloric acid (HCl), gaseous state organic acid (formic acid, acetic acid, oxalic acid etc.) etc., their concentration is in an atmosphere low, harm is large, how to its accurate acquisition with to measure be key issue in current environmental monitoring.In atmospheric environment, the state that primary water-soluble gaseous contaminant and airborne particulate state pollutant, common gases etc. are in Homogeneous phase mixing, balance each other, the prerequisite of its concentration of Accurate Determining gets rid of the interference, the particularly interference of particulate form pollutant of other materials in mixed state.Conventional solid detention method and condensation at low temperature all can not separating gaseous and particulate form atmosphere pollutions effectively, and during sampling, mutual interference ratio is between the two comparatively large, and collection efficiency is not high.And spread apart trapping technique can get rid of the interference between gas and particle well, be applied to the sampling of Atmospheric Trace pollutant in recent years.
The theoretical foundation of diffusion trapping technique is that gas and particle rate of diffusion difference are very large, in certain stroke range, gas is far longer than particle in the diffusion of air-flow longitudinal direction, now select particular absorber to catch the fast species of gases of diffusion at longitudinal direction, thus reach the object being separated noiseless divided gas flow and particle.Difform anemostat is had according to such principle design, absorbing agent is attached to anemostat inwall, gas molecule is diffused on tube wall trapped by absorbing agent, and particle is unaffected, can one straight through anemostat, measured by corresponding detecting instrument by the gas that absorbing agent traps, thus the concentration of the Gaseous Pollutants be captured can be obtained.For trapping the anemostat at least following condition of demand fulfillment of Gaseous Pollutants: 1, the material of anemostat needs affine absorbing liquid; 2, because Gaseous Pollutants concentration is low, anemostat wants high to the arresting efficiency of gaseous contaminant; 3, anemostat keeps stable to the arresting efficiency of gaseous contaminant in relatively long-time; 4, avoid interference the loss of composition granule thing in anemostat as far as possible; 5, because Gaseous Pollutants fluctuation of concentration scope is large, the capacity of the trapping gaseous pollutant of anemostat wants large.Foreign study person is designed with circular propagation pipe, annular denuder, parallel plate type anemostat etc. as the case may be, their application scenario is different, all there are respective relative merits, wherein because the inside surface of annular denuder is large, capacity large, are often applied to the trapping of Gaseous Pollutants.
Annular denuder conventional in the world at present has following defect: 1, unstable to the arresting efficiency of gaseous contaminant; 2, low to the trapping capacity of gaseous contaminant, under the environment of high pollution especially abroad, use in the world good annular denuder at home environmental applications time usually lost efficacy; 3, structure is partially complicated, and cause later maintenance loaded down with trivial details, cost is high.
