Abstract
The utility model relates to a marsh gas pretreating device, which comprises a separator, a fan, a desulphurization tower, a cooling and dewatering device and a fine filter. The marsh gas is firstly jointed in the separator, and then the separator removes the corresponding impurities and the fan is used to push the marsh gas to flow in the device, and then the marsh gas flows to the desulphurization tower and removes the corresponding sulfur gases and removes the water vapor in the cooling and dewatering device. The marsh gas after dewatering enters the fine filter and is supplied to the application equipments (inner gas and boiler) to work. The utility model is designed by the purity technology of separating, desulphurization, dewatering and further filtering and can effectively enter the marsh gas to perform purification treatment, which avoids the short operation life of the application equipments due to the marsh gas erosion and increases the utilization ratio of the marsh gas and the working efficiency of the application equipments. The utility model has the advantages of novel and simple structure and strong practicability.
Description
Technical field
The utility model relates to the technical field of biogas pretreatment unit, and it can be widely used in industrial occasions such as generating, gas.
Background technology
Biogas is exactly the gas in the marsh as its name suggests.People often see in swampland, side bilge or manure pit, having bubble to come up, and, just light it the biogas of the natural generation of nature that Here it is if we are drawing match so long.At present, biogas also can be by various organic substances at secluding air (reductive condition) and under suitable temperature, humidity, and the fermentative action of process microorganism obtains; Wherein, no matter be natural or the biogas that manually obtains, its main component is a methane, and methane is a kind of ideal geseous fuel, its colorless and odorless; At present, countries in the world have begun biogas is widely used in occasions such as generating, gas as fuel; But general biogas complicated component also contains a large amount of obnoxious flavoures and rare gas element, such as sulfurous gas (SO except methane
2), hydrogen sulfide (H
2S) sulfurous gas, carbonic acid gas (CO such as
2) wait carbonaceous gas, wherein, obnoxious flavoures such as sulfur-bearing can application device produce corrosion, make application apparatus operation life short, and gases such as carbon containing can have influence on the working efficiency of application apparatus etc.; So must anticipate accordingly before using biogas, for example at Chinese patent application number 200610040318.8 disclosed biomass marsh gas preprocessing systems, its structure is comparatively complicated, and technology is loaded down with trivial details, has disappearances such as operation inconvenience.
The utility model content
The utility model is at the existing disappearance of above-mentioned prior art, main purpose is to provide a kind of simple in structure, biogas pretreatment unit that decontamination effect improving is good, and it has solved the short and not high problem of utilization ratio of the burn into operation life that influences application device in the biogas industrial applications for a long time.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of biogas pretreatment unit, it comprises:
One is used to handle biogas separate impurities device;
One blower fan, this blower fan is communicated with separator;
One thionizer, this thionizer is communicated with blower fan;
One cooled dehydrated device, it is communicated with thionizer; And
One secondary filter, this secondary filter is communicated with the cooled dehydrated device.
Described cooled dehydrated device is connected in sequence by high temperature cooling device, subcooler, dewatering unit, and this high temperature cooling device is communicated with blower fan, and dewatering unit is communicated with secondary filter.
The advantage of the utility model be by separation, desulfurization, dehydration more further the purification process of filtration design, can make the biogas that enters wherein carry out purifying treatment effectively, avoid application apparatus to be subjected to biogas corrosion and the phenomenon of its operation life weak point is taken place, and also strengthen the biogas utilization rate, promote the working efficiency of application apparatus.The utility model novel structure, simple and practical.
Description of drawings
Fig. 1 is the utility model one-piece construction connection diagram.
The drawing reference numeral explanation:
10, separator 20, blower fan 30, thionizer 40, cooled dehydrated device 41, high temperature cooling device 42, subcooler 43, dewatering unit 50, secondary filter
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, a kind of biogas pretreatment unit comprises separator 10, blower fan 20, thionizer 30, cooled dehydrated device 40 and secondary filter 50, wherein:
Thionizer 30, this thionizer 30 is communicated with blower fan 20, and it can be by the chemical replacement reaction with sulfurous gas (SO in the biogas
2, H
2S etc.) handle, to prevent to enter the phenomenon generation that produces corrosion in the application apparatus and cause the operation life weak point.
Cooled dehydrated device 40, it is connected in sequence by high temperature cooling device 41, subcooler 42, dewatering unit 43, and this high temperature cooling device 41 is communicated with thionizer 30, and dewatering unit 43 is communicated with secondary filter 50; The structure design of this cooled dehydrated device 40 can guarantee to remove the effect of water vapour in the biogas better.
The utility model principle of work: earlier biogas is inserted in the separator 10 by pipeline, remove behind the corresponding impurity through blower fan 20 by separator 10, utilizing the work of this blower fan 20 to promote biogas flows in device, flow into then and remove corresponding sulfurous gas in the thionizer 30, slough water vapour in the high temperature cooling device 31 of process cooled dehydrated device 30, subcooler 32, the dewatering unit 33 successively again, biogas after the dehydration enters in the secondary filter 40, offers application apparatus (interior combustion gas, boiler) at last and carries out work; Its by separation, desulfurization, dehydration more further the purification process of filtration design, can make the biogas that enters wherein carry out purifying treatment effectively, avoid application apparatus to be subjected to biogas corrosion and the phenomenon of its operation life weak point is taken place, and also strengthen the biogas utilization rate, promote the working efficiency of application apparatus.The utility model novel structure, simple and practical.
In sum, it only is the preferred embodiment of a kind of biogas pretreatment unit of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
