Technical field
This utility model relates to biogas detection field, it is specifically related to the integrated on-line analysis device of a kind of biogas component, mainly realize the on-line checking of biogas component, it is used for monitoring bionethanation system, such as anaerobic system, biogas desulfurization system and biogas comprehensive utilization system, realize the purpose of on-line checking, it is simple to the comprehensive utilization of biogas.
Background technology
Containing multiple gases component in biogas, being wherein mainly methane and carbon dioxide, possibly together with minimum gas such as a small amount of hydrogen sulfide, carbon monoxides, the comprehensive utilization of biogas is had very important significance by the component analyzing biogas.
It is methane that biogas main utilizes composition, and the comprehensive utilization of biogas is played deciding factor by the content of methane.Therefore, the detection of methane content is particularly important.The simultaneously analysis of methane in sewage gas and hydrogen is one of most direct indicator judging anaerobic fermentation system duty, and the content analyzing methane and hydrogen both gas is to regulate and control significant to biogas production.
The biogas key component produced by anaerobic fermentation is methane, and contains the hydrogen sulfide of trace in biogas.In biogas utilization process, equipment can be caused serious corrosion by hydrogen sulfide, it is therefore necessary to by hydrogen sulfide removal before biogas utilization, therefore realizes the on-line checking of hydrogen sulfide is just particularly important when biogas utilization.Microcomponent in biogas is also required by some marsh gas treatment technologies, for instance will strictly control the oxygen content in biogas, because oxygen remains in the danger in biogas easily caused by blast.So trace gas component is also particularly significant for biogas whole system in analysis biogas.
Gas detector function singleness conventional at present, the detection to a certain pure gas can only be realized, and sample gas is required dustless, anhydrous and oil-free by on-site detecting device, it is easily subject to the impact of the factor such as testing staff, environment, can there is certain error in testing result, on-line checking can not be realized, be inconvenient in actual applications.Therefore, it is necessary to provide a kind of being capable of biogas carries out pretreatment and detects the device of various ingredients simultaneously.
Summary of the invention
This utility model is in order to overcome the deficiency of above technology, it is provided that a kind of device being capable of the on-line checking simultaneously of gas component in biogas.
This utility model overcomes its technical problem be the technical scheme is that
A kind of integrated on-line analysis device simultaneously detecting biogas component, including: the valve being connected to biogas pipeline, the sample gas filter being connected to valve, the particulate filter being connected to sample gas filter, the some air chambers mutually connected in series being connected to particulate filter and some gas analysers, sample gas filter is connected to draining pump, some being connected with corresponding air chamber for detecting the gas analyser of gas with various content in biogas, described some gas analysers are connected to signal receiving end.
In order to improve filter effect further, also include the membrane filter being connected to particulate filter with air chamber.
For the ease of controlling charge flow rate, also include the sample gas effusion meter being connected to membrane filter with air chamber.
The beneficial effects of the utility model are: when needing the biogas in biogas pipeline is carried out on-line checking, and after Open valve, biogas first passes through sample gas filter and filters out moisture therein, it is possible to discharged by the water filtered by draining pump.Biogas filters particulate matter therein then through particulate filter afterwards, and pure biogas enters in air chamber, and the content of the biogas each component in air chamber is detected by each gas analyser, and feedback signal reception end.Achieve to on-line checking while the components such as biogas filtration, dehumidifying and methane in sewage gas, hydrogen sulfide, oxygen, carbon dioxide, improve the convenience in practical application.
