Description
Technical field
The present invention relates to gas on-line analysis systems technology field, particularly relate to a kind of high-dust flue gas sampler.
Background technology
Flue gas component comprises main gas component and trace harmful gases component.Main gas component is nitrogen, oxygen, carbon dioxide and water vapor etc.The object measuring these components investigates fuel combustion situation and provides calculating smoke density, the isoparametric data of molecular weight for flue dust measures.Harmful constituent is carbon monoxide, oxides of nitrogen, oxysulfide and sulfuretted hydrogen etc.Because gaseous state and steam-like material molecule distribute relatively more even in flue, do not need multi-point sampling, all can collect representative gas sample in any point near flue center.Meanwhile, gas molecule quality is minimum, can not consider inertia effect, therefore also not need isokinetic sampling, and its general sampling apparatus shows See Figure.If when needing gas sample amount less, the syringe of appropriate solvent can be used to sample, or by bulbs,double, gas sample is pressed in polybag at syringe interface place.As directly measured with instrument at the scene, then gas is passed through sampling pipe, dehumidifier suction analytical instrument with aspiration pump.Because smoke moisture is large, temperature is high, flue dust and harmful gas concentration large, and have corrosivity, therefore at sampling pipe head, smoke filter is housed, sampling pipe needs heating or insulation and corrosion-resistant, prevents water vapor condensation and causes tested component to be lost.Be sampled gas after heated at constant temperature pipe, absorption bottle, drying, flow through orifice metre, microprocessor is sent to process flow signal, draw instantaneous delivery and accumulated samples volume, and according to pressure before temperature before the meter collected and meter, be converted into mark condition volume, when sample streams value is different from setting flow, the power of bleeding of automatic adjustment sampling pump, makes sampling flow constant in setting value.
Tradition flue gas sampler maintenance under rugged environment is large, easily by blockings such as dust, moisture, tar in sample gas.Want frequent more renew cartridge, sampler is smoke collecting device, and filter core is wherein that sample gas first filters, because he is operated in the environment of high temperature, high dust, if design irrational words life cycle sometimes only have tens hours.On-line monitoring and the analysis of gas need continuity, this generates contradiction.
Summary of the invention
Based on the technical matters that background technology exists, the present invention proposes a kind of high-dust flue gas sampler.
A kind of high-dust flue gas sampler that the present invention proposes,
A kind of high-dust flue gas sampler, comprise rain cover, described rain cover side is provided with anti-burst temperature controller, the inner chamber upper end of described rain cover has sample gas to export and sweep gas entrance by support installing, the both sides, lower end of described sample gas outlet and sweep gas entrance are provided with heat insulation and heating equipment, the inwall of described heat insulation and heating equipment is provided with sampler protective cover, the inner chamber of described sampler protective cover is provided with two spacing stainless steel mesh, described spacing stainless steel mesh is provided with elasticity smoke filter between any two, the both sides, upper end of described spacing stainless steel mesh are separately installed with ultramicropore SiC high efficiency particulate air filter, the side of described heat insulation and heating equipment is provided with pneumatic vibrator, the downside of the spacing stainless steel mesh of described lower end is provided with mounting flange, the middle part of described mounting flange is provided with sampler feeler lever, the side of described sampler feeler lever extends to the outside of rain cover, described sampler feeler lever is provided with dust cover away from the side of mounting flange.
Preferably, described sample gas sampler is connected with process pipe by mounting flange, chooses corresponding feeler lever length according to process pipe size, and insertion depth is flue diameter 1/5 ~ 4/5.
Preferably, described dust cover can effectively reduce sample gas velocity, reduces the dust entering sampler.
Preferably, it is inner that described sample gas enters elasticity smoke filter by sampler feeler lever, dust is blocked in the gap being full of filter medium inside, its dust containing capacity of onesize filtrator increases greatly, be extend the important measures of maintenance period, again because time of filtration becomes large automatically when deashing, be easy to the grit be blocked in gap to clear out, without the need to pulling down the maintenance works such as cleaning, flue gas enters ultramicropore SiC high efficiency particulate air filter through first order elasticity filter element filtering.
Preferably; pneumatic vibrator aggravation vibration is installed additional outside described sampler protective cover; reduce dust at filter surfaces adhesion; in addition; also outside rain cover, anti-burst temperature controller is housed, outside sampler protective cover, is provided with heat insulation and heating equipment, by anti-burst temperature controller heating and temperature control constant temperature 140 DEG C; ensure that the gas temperature entering sampler is higher than dew point, there will not be condensation.
In the present invention, by having dust cover in sampler feeler lever tip designs, dust cover can reduce the flow velocity of tested gas in process pipe, and flow velocity reduces large dust and can automatically sink due to self gravitation effect, reduces the dust entering sampler; Medium sized dust granules can be allowed to stay elasticity smoke filter surface by introducing elasticity smoke filter, greatly reducing the blocking of rear class filtrator.Filter core gap is less can stop most of dust in flue gas when filtering for elasticity smoke filter 1, but when purging because purge gas pressure causes greatly elasticity smoke filter filter core gap to become large, be so just easy to go out adhering to dust cleaning in the filter; In the environment of high dust, high-moisture, only relying on elasticity smoke filter to be nowhere near, because dust easily hardens in the environment of high humility, introducing gas shock for addressing this problem this practicality; By introducing ultramicropore SiC high efficiency particulate air filter surface filtration filter core, there is vapour lock little, the feature such as corrosion-resistant.In addition this practicality provides constant temperature heating device guarantee flue gas can not form aqueous water in sampler.
