The vent gas treatment assembly of a kind of marsh gas power generation unit of the utility model; Through a flue gas heat exchange device is set on the exhaust pipe of emission power generation unit; Water circulating pipe with the heat transferred flue gas heat exchange gas in the tail gas; Not only can effectively be used, more can reduce the pollution of tail gas through reducing the temperature of tail gas to atmosphere to the heat in the tail gas.
Description of drawings
Shown in Figure 1 is the vent gas treatment assembly embodiment's one of a kind of marsh gas power generation unit of the utility model structural drawing.
Embodiment
Shown in Figure 1 is the vent gas treatment assembly embodiment's one of a kind of marsh gas power generation unit of the utility model structural drawing; The structure of the vent gas treatment assembly of a kind of marsh gas power generation unit of the utility model does; The exhaust pipe 8 of marsh gas power generation unit connects a flue gas heat exchange device 1, has water circulating pipe in the flue gas heat exchange device 1, and; Flue gas heat exchange device 1 has the space of ccontaining tail gas, and the pipe main body of above-mentioned water circulating pipe 2 passes this space.
In embodiment one; Tail gas in the exhaust pipe 8 gets into an end of flue gas heat exchange device 1; Water circulating pipe 2 is tortuous repeatedly being arranged in the space of ccontaining tail gas in flue gas heat exchange device 1, and the temperature of the water temperature ratio exhaust gas in the water circulating pipe 2 is low, so just with the circulating water in the heat transferred water circulating pipe in the tail gas 2; Tail gas after the other end of flue gas heat exchange device will be lowered the temperature is discharged; Not only played the effect that reduces exhaust temperature, can heat to circulating water simultaneously, the circulating water after the heating can be used for aspects such as heating, bathing and insulation.
The embodiment two of the vent gas treatment assembly of the utility model marsh gas power generation unit, as shown in Figure 1, between exhaust pipe 8 and flue gas heat exchange device 1, also be provided with a pyrolysis apparatus 3.Because contain a large amount of carbon granules in the tail gas, directly in the exhausting air, can pollute air, therefore, this pyrolysis apparatus 3 is set, with the carbon granule in the cracking tail gas.
The embodiment three of the vent gas treatment assembly of the utility model marsh gas power generation unit, as shown in Figure 1, a primary heater 4 is arranged on the water circulating pipe 10 of marsh gas power generation unit, and primary heater 4 is arranged on before the flue gas heat exchange device 1.One side of this primary heater 4 has 4 interfaces that are connected with exhaust pipe 7, and the downside of primary heater 4 is communicated with exhaust pipe 8.
In present embodiment three; The purpose that primary heater 4 is set mainly is to utilize the heat of vigor generator set tail gas to keep the temperature of the circulating water of marsh gas power generation unit; Because the circulating water of marsh gas power generation unit need keep certain temperature, so that the marsh gas power generation unit can proper functioning.A three-way valve can be set on the water circulating pipe of marsh gas power generation unit, and three ends of this three-way valve connect three sections said water circulating pipes respectively, and wherein two sections said water circulating pipes are at the normal water circulating pipe of vigor generator set; And the circulating water water temperature just often these two pipelines keep conducting through three-way valve; Another section then is the water circulating pipe 10 shown in Fig. 1, inserts in the primary heater 4, when the temperature of circulating water is not enough; Can be with water circulating pipe 10 conductings; So that circulating water flow is through primary heater 4, and after heating through primary heater 4, circulation gets into the marsh gas power generation unit again.Because primary heater 4 volumes are less, and the required temperature of water circulating pipe 10 is higher, therefore can be arranged on before the flue gas heat exchange device 1, makes and when tail gas temperature is higher, can the circulating water of marsh gas power generation unit be heated
The embodiment four of the vent gas treatment assembly of the utility model marsh gas power generation unit; As shown in Figure 1; An one-level silencing apparatus 5 and a secondary muffler 6 are communicated with; One-level silencing apparatus 5 is positioned at before the secondary muffler 6, and one-level silencing apparatus 5 is connected with the tail gas exhaust port of flue gas heat exchange device 1, and the exhaust port of secondary muffler 6 is connected with exhaust pipe 9.
Owing to the marsh gas power generation unit can produce very big noise in running, and noise can pass to the outside along with the eliminating pipeline of tail gas, in the present embodiment four, reduces along with the outside noise of propagating of exhaust pipe through one-level silencing apparatus 5 and secondary muffler 6.Tail gas successively flows through one-level silencing apparatus 5 and secondary muffler 6; Through exhaust pipe 9, just can standard compliantly be discharged in the air, certainly; Also can further increase some filtrating equipments; Further to reduce the pollution of tail gas, those skilled in the art can be provided with according to demand flexibly, seldom do at this and give unnecessary details.
In sum; The vent gas treatment assembly of a kind of marsh gas power generation unit of the utility model; Through a flue gas heat exchange device is set on the exhaust pipe of emission power generation unit, the water circulating pipe with the heat transferred flue gas heat exchange gas in the tail gas not only can effectively be used to the heat in the tail gas; More can reduce the pollution of tail gas through reducing the temperature of tail gas to atmosphere.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
