Description
Technical field
This utility model relates to gas on-line analysis systems technology field, particularly relates to a kind of high-dust flue gas sampler.
Background technology
Flue gas component includes main gas component and trace harmful gases component.Main gas component is nitrogen, oxygen, carbon dioxide and steam etc..The purpose measuring these components is to investigate fuel combustion situation and measure offer calculating smoke density, the isoparametric data of molecular weight for flue dust.Harmful constituent is carbon monoxide, nitrogen oxides, oxysulfide and hydrogen sulfide etc..Due to gaseous state and steam-like material molecule, to be distributed ratio in flue more uniform, it is not necessary to multi-point sampling, all can collect representative gas sample in any point near flue center.Meanwhile, gas molecule quality is minimum, can be left out effect of inertia, therefore also without isokinetic sampling, its general sampling apparatus See Figure.If need gas sample amount less, the syringe of appropriate solvent can be used to sample, or by bulbs,double, gas sample is pressed in plastic bag at syringe interface place.As directly measured with instrument at the scene, then with air pump, gas is passed through sampling tube, dehumidifier suction analytical tool.Because smoke moisture is big, temperature is high, and flue dust and harmful gas concentration are big, and have corrosivity, therefore at sampling tube head equipped with smoke filter, sampling tube needs heating or insulation and corrosion-resistant, it is prevented that water vapor condensation and cause that tested component is lost.It is 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 accumulated samples volume, and according to pressure before temperature before the meter collected and meter, it is converted into mark condition volume, when sample streams value is different from setting flow, it is automatically adjusted the power of bleeding of sampling pump, makes sampling flow constant in setting value.
Tradition flue gas sampler maintenance under rugged environment is big, it is easy to blocked by dust, moisture, tar in sample gas etc..Frequently changing filter element, sampler is smoke collecting device, and filter element therein is that sample gas first filters, owing to he is operated in the environment of high temperature, high dust, if designing irrational words life cycle sometimes only have tens hours.The on-line monitoring of gas and analysis need seriality, this generates contradiction.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of high-dust flue gas sampler proposed.
To achieve these goals, this utility model adopts the technical scheme that
nullA kind of high-dust flue gas sampler，Including rain cover，Described rain cover side is provided with anti-burst temperature controller，The inner chamber upper end of described rain cover is provided with sample gas outlet by support and purges gas entrance，The both sides, lower end of the outlet of described sample gas and purging 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 meshs，Described spacing stainless steel mesh is provided with elastic 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，The side of the described remotely mounted flange of sampler feeler lever is provided with dust cover.
Preferably, the side of described rain cover is provided with control knob, and the side of control knob is provided with shoe.
Preferably, the side of described rain cover is provided with a support arrangement, and the lower end of a support arrangement is provided with fixing device.
Preferably, described sampler feeler lever is inserted through mounting flange away from one end of dust cover and is connected with spacing stainless steel mesh.
In this utility model, 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 big dust and can automatically sink due to self gravitation effect, reduces the dust entering sampler；Medium sized dust granules can be allowed to stay flexible filter surface by introducing elastic material filter, greatly reduce the blocking of rear class filter.Flexible filter filter element gap when filtering is less can stop major part dust in flue gas, but when purging owing to purging gas pressure causes that greatly flexible filter filter element gap becomes big, is thus easy to go out adhering to dust cleaning in the filter；High dust, high-moisture environment in rely solely on flexible filter and be also nowhere near because dust easily hardens in the environment of high humility, introduce gas shock for solving this this practicality of problem；By introducing ultramicropore surface of SiC 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 will not form aqueous water in sampler.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-dust flue gas sampler that the utility model proposes.
In figure: 1 elastic smoke filter, 2 spacing stainless steel meshs, 3 sampler protective covers, 4 heat insulation and heating equipments, 5 sampler feeler levers, 6 dust covers, 7 anti-burst temperature controllers, 8 ultramicropore SiC high efficiency particulate air filters, 9 rain covers, 10 sample gas outlets and purging gas entrance, 11 pneumatic vibrators, 12 mounting flanges.
