Embodiment Construction

[0020] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the present invention provides a kind of HO in the atmospheric gaseous pollutant that is suitable for mooring airship 2 Free radical online measurement system, including airship 1, online measurement of HO 2 Radical component 2, air intake pipe 3 and battery power system 4.

[0022] The airboat 1 includes an airboat body 11 , a suspension basket 12 , a counterweight 13 , cables 14 and a cable control motor 15 .

[0023] The airboat body 11 has buoyancy after being filled with helium, so that the airboat 1 can rise to any height. The suspension basket 12 is suspended below the airboat body 11 through suspension wires 16 . The counterweight 13 is evenly arranged on the outside of the hanging basket 12 to keep the hanging basket 12 in a balanced state. One end of the cable 14 is connected to the center ...

Abstract

The invention discloses an on-line measurement system for HO2 free radicals in atmospheric gaseous pollutants suitable for airship mooring. The on-line measurement system comprises an airship, an on-line HO2 free radical measurement part and a gas inlet pipe, wherein the on-line HO2 free radical measurement component is arranged in a hanging basket of the gas boat and comprises a filter, a mixer,a heating pipe, a high-pressure reaction pipe, a measurement chamber unit and a gas pump, which are sequentially arranged in the gas flowing direction. Laser emitted by the laser generation emitter isinduced to be emitted into the high-pressure reaction tube, gas is reacted in the high-pressure reaction tube under the induction of the laser so taht HO2 free radicals are generated; the laser detector emits laser to penetrate through the measuring chamber unit, wherein the laser is absorbed by HO2 free radicals in the measuring chamber unit when penetrating through the measuring chamber unit, then the intensity of the laser attenuates, the laser receiver receives the laser penetrating through the measuring chamber unit, and the concentration of the HO2 free radicals is obtained according tothe attenuation amount of the laser intensity. The method has the advantages of accuracy, high efficiency, stability and the like.

Description

technical field [0001] The invention belongs to the field of environmental measurement, and relates to a method for measuring HO in atmospheric gaseous pollutants 2 Free radical online measurement system, especially related to HO in atmospheric gaseous pollutants suitable for moored airships 2 Free radical online measurement system. Background technique [0002] Atmospheric active HO 2 Free radicals are initiators and catalysts of atmospheric photochemical reactions, and play a key role in the formation of haze and the balance of ozone in the troposphere, and their concentration levels can be used as an important indicator to measure the oxidation level of the atmosphere itself. Atmospheric HO 2 Free radicals are an important intermediate product in atmospheric chemical processes, and an important medium for the removal of primary pollutants and the generation of secondary pollutants. Therefore, the field measurement of atmospheric peroxyl radicals is helpful to understa...
