Abstract
A device for purifying ozone gas belongs to the technical field of atmospheric monitoring equipment, is used to purify ozone gas used in a nitrogen oxide automatic monitor, and adopts technical scheme as follows: the device is composed of a purification reaction chamber, ozone purification reagent and metal meshes, wherein the purification reaction chamber is a hollow chamber, the ozone purification reagent is placed in the chamber of the purification reaction chamber, two ends of the purification reaction chamber are provided with a gas inlet and a gas outlet for purified gas respectively, and the metal meshes are installed between the gas inlet and the ozone purification reagent and between the gas outlet and the ozone purification reagent. According to the invention, fine pored silica gel of the ozone purification reagent in the purification reaction chamber has a larger surface area and small holes, so as to absorb moisture, nitrate, sulfate aerosol and other components in purified ozone gas, further achieve the purpose of purifying ozone, and ensure accurate measurement of NO and NO2. The device disclosed by the invention has the advantages of simple structure, convenience for maintenance and the like, and is particularly suitable for matching with the nitrogen oxide automatic monitor for use.
Description
Technical field
The present invention relates to a kind of device of purification ozone gas, relate in particular to the purification plant of the employed ozone gas of oxides of nitrogen automonitor, belong to the atmospheric surveillance equipment technical field.
Background technology
Ozone is that pollutant chemistry is poisoned the main participator who develops and urged power in the air, is the main monitoring target of pollutant harm in the prediction air.Because the physics and the chemical property of ozone itself make ozone standard gas can not adopt the method for traditional gas standard material to prepare, store and transport.Prepare the method that ozone standard gas must adopt " promptly join promptly and use ", this has just increased the difficulty of ozone standard gas preparation and storage.
At present, the on-line monitoring appearance of chemoluminescence method is adopted in the oxides of nitrogen monitoring usually, needs to use excessive ozone (O
3) reacting with airborne nitrogen monoxide (NO) generates the nitrogen dioxide (NO of excited state
2*), the nitrogen dioxide (NO of excited state
2*) molecule is got back to low-energy state through ballistic phonon to discharge unnecessary energy, and its luminous intensity is directly proportional with the concentration of NO, through detecting the concentration that luminous intensity obtains NO.Wherein need adopt ozone generator to produce excessive O
3If but the air dried inadequate words that get into ozone generator, the O of generation
3Just impure, contain small gasoloid impurity such as a large amount of nitrate, sulfate, on the optical filter of reaction chamber, form one deck wax, seeing through of block light influences the accurate monitoring of NO, and serious words also can the corrosion reaction chamber and pipeline etc.Therefore, ozone gas is purified accuracy rate that just becomes raising NO and the requisite measure of protecting monitoring equipment.
Summary of the invention
Technical matters to be solved by this invention is the deficiency that overcomes prior art, and the device of the purification ozone gas of impurity such as a kind of nitrate that is used for purifying impure ozone, sulfate is provided.
The technical scheme that solves the problems of the technologies described above is:
A kind of device of purification ozone gas; It is formed by purifying reaction chamber, ozone purification reagent and wire netting; Purifying reaction chamber is the chamber of hollow; Ozone purification reagent is positioned in the chamber that purifies reaction chamber, and the two ends that purify reaction chamber have the air intake opening and the gas outlet of Purge gas respectively, between air intake opening and the ozone purification reagent, between gas outlet and the ozone purification reagent wire netting is housed respectively.
The device of above-mentioned purification ozone gas, said ozone purification reagent are the Kiselgel As of some.
The device of above-mentioned purification ozone gas, the aluminium that said purification reaction chamber is stainless steel or special processing etc. not with the material of ozone reaction.
Usefulness of the present invention is:
Ozone purification reagent Kiselgel A in the purification reaction chamber of the present invention has bigger surface area and aperture, can to reach the purpose of purification ozone, guarantee NO and NO to absorption such as the moisture in the ozone gas that is cleaned, nitrate, sulfate aerosol
2The accurate measurement of concentration is for the monitoring of environmental atmospheric condition provides reference.The present invention has advantages such as simple in structure, easy to maintenance, is specially adapted to the supporting use of oxides of nitrogen automonitor.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present invention.
Mark is following among the figure: purify reaction chamber 1, ozone purification reagent 2, wire netting 3, air intake opening 4, gas outlet 5.
Embodiment
The present invention forms by purifying reaction chamber 1, ozone purification reagent 2 and wire netting 3.
Show among the figure that the purification reaction chamber 1 of one embodiment of the present of invention is two cylinder shape structures, the upper end of two cylinders is respectively equipped with import and export 4 and gas outlet 5, and the lower end has communicating pipe to be connected.
Show among the figure; Being filled in the ozone purification reagent 2 that purifies in the reaction chamber 1 is Kiselgel As of some; Kiselgel A has bigger surface area and aperture, can be absorption such as the moisture in the ozone gas that is cleaned, nitrate, sulfate aerosol, to reach the purpose of purification ozone.
Show among the figure, the aluminium etc. that purifies reaction chamber 1 and be stainless steel or special processing not with the material of ozone reaction, can not produce other impurity, to guarantee the purity and the reliability of purification.
The present invention places between the ozone generator and reaction chamber of oxides of nitrogen automonitor in use, air intake opening 4, gas outlet 5 respectively with the oxides of nitrogen automonitor in ozone generator be connected with reaction chamber.Its course of work is following: air gets into ozone generator through exsiccator; In ozone generator, produce ozone through effluve; Ozone gets into reaction chamber through behind the present invention; In reaction chamber, carry out chemical reaction, the monitoring personnel are according to the concentration value of nitrogen monoxide, nitrogen dioxide and oxides of nitrogen in the chemiluminescence reaction principle monitoring atmosphere.
