Technical field
This utility model relates to a kind of TRT, particularly relates to a kind of marsh gas power generation and waste-heat recovery device.
Background technology
In technique for treating industrial wastewater, often use anaerobic treatment.Substantial amounts of natural pond is often produced during anaerobic treatment
Gas, biogas is enriched in the biomass gas of methane, and methane content is up to more than 70%, and calorific value is more slightly higher than town gas, is very
Good gaseous fuel, has good value.Biogas is also pollution gas simultaneously, containing sulfide gas (hydrogen sulfide,
The organic sulfur compounds such as mercaptan, thioether, thiophene), ammonia, stench or the irritative gas such as halogen gas, have a strong impact on big compression ring
Border quality.The additionally methane in biogas or strong greenhouse gases, its equivalent quality is 21 times of carbon dioxide.Therefore resource
Changing utilizes biogas to have multiple economic worth and environmental value.
In the prior art, biogas is typically transported in common methane power generating system, is not utilized effectively, and
Biogas generator not through reclaiming, causes the waste of resource from produced high-temperature flue gas during in generating.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of biogas to send out
Electricity and waste-heat recovery device, its simple in construction, it is convenient to run, and not only greatly reduces the operating cost of Sewage Disposal, and
Improve the temperature of waste water, it is ensured that anaerobic ferment process properly functioning.
This utility model solves its technical problem and be the technical scheme is that
Described marsh gas power generation and waste-heat recovery device, high-concentration industrial-water storage tank and wastewater equalization pond, anaerobic reaction
Device and subsequent processing units are sequentially connected；Anaerobic reactor and methane holder, desulfurizing tower, surge tank, moisture trap, back-fire relief
Device and Biogas Generator Set are sequentially connected；Biogas Generator Set is sequentially connected with heat recovery boiler and plate type heat exchanger.
Described Biogas Generator Set is respectively connected with sewage treatment plant and workshop, i.e. Biogas Generator Set sends
Electricity can directly feed workshop and use, convenient and swift.
Described Biogas Generator Set is automatically controlled outer mixed lean-burn so that the ratio of oxygen is higher, beneficially fuel
Fully burning, solves tempering, phenomenon of blowing out that common outer mixed machine exists, improves economy and the safety of electromotor.
Described plate type heat exchanger is connected with wastewater equalization pond, and the heat in plate type heat exchanger is for improving wastewater equalization pond
Temperature.
The cooling water circulation unit of described Biogas Generator Set is semi-open type dual temperature Two-way Cycle mode, by low temperature water pump respectively
The engine interior closed circuit cooling system formed with high and low temperature heat exchanger, and outer cooling system is to high and low warm friendship
Electromotor is lowered the temperature by parallel operation and cooling tower, the external circulation cooling system of water pump composition, cooling effective, and is unlikely to make
Impurity enters engine interior, substantially prolongs its service life.
Described surge tank has cushioning effect to the change of biogas air pressure, thus avoids the frequent starting of pressure charging system,
Also can guarantee that stable gas pressure, favourable to subsequent processing units.
This utility model is had the beneficial effect that
This utility model simple in construction, it is convenient to run, and the biogas that can effectively utilize waste water to produce in anaerobic fermentation enters
Row generating, in addition to supplying self Sewage Disposal and utilizing, remaining part also adds to workshop, greatly reduces sewage disposal
The operating cost stood, Biogas Generator Set, is used for from produced high-temperature flue gas during in generating after waste heat recovery simultaneously
Improve the temperature of waste water, thus ensure that the properly functioning of anaerobic ferment process.
