Description

The methane fuelled engine waste heat recycling system
[technical field]
The utility model belongs to the methane fuelled engine energy-saving emission-reducing apparatus, is specifically related to a kind of methane fuelled engine waste heat recycling system.
[background technique]
The a large amount of hot water of cylinder sleeve cooling generation was directly lowered the temperature with fan cooling when methane fuelled engine was worked usually; And the waste gas of discharging passes through silencing apparatus, outlet pipe directly to air venting.And the water outlet of methane fuelled engine jacket-cooling water is compared with water inlet many temperature rises is arranged, and its temperature of smoke waste gas of discharging reaches about 600 ℃.Directly to environmental emission, not only wasted the energy but also polluted environment.And the most complex structure of equipment of at present waste heat of methane fuelled engine discharging being recycled, cost is high.
[model utility content]
Technical problem to be solved in the utility model is to provide a kind of simple in structure, the methane fuelled engine waste heat recycling system that can fully recycle the waste heat of the cylinder sleeve of methane fuelled engine discharging and tail gas; it can satisfy the environmental protection of country and the requirement of renewable energy utilization policy, reaches the purpose of energy-saving and emission-reduction.
The utility model solves the problems of the technologies described above by the following technical solutions:
The methane fuelled engine waste heat recycling system comprises methane fuelled engine, recycle pump, tail gas heat exchanger, buffer tank, uses hot equipment, described methane fuelled engine to connect respectively described recycle pump and described tail gas heat exchanger; Described recycle pump connects described tail gas heat exchanger; Described tail gas heat exchanger connects the described hot equipment of using; The described buffer tank of the hot equipment connection of described usefulness; Described buffer tank is connected to described methane fuelled engine.
Further, the hot equipment of described usefulness can be the heating equipment of piglet insulating bed.
Further, the hot equipment of described usefulness also can be the animal drinking water heating equipment
Further, the hot equipment of described usefulness can also be the heating equipment of anaerobism generator.
The utility model has the advantage of: the utility model adopts water/exhaust-heat exchanger series connection to reclaim heat, jacket-cooling water is after exhaust gas heat exchanger further heats, make the temperature of methane fuelled engine discharging flue gas drop to 300 ℃ from about 600 ℃, nearly 60% of recoverable methane fuelled engine discharges heat, the waste heat that reclaims can be used for the intensification of mathane generating pool feed liquid, perhaps heating, make the waste heat of methane fuelled engine obtain fully recycling, reach the purpose of energy recovery and resource reutilization.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 the utility model structural representation.
[embodiment]
As shown in Figure 1, the methane fuelled engine waste heat recycling system comprises methane fuelled engine 1, recycle pump 2, tail gas heat exchanger 3, buffer tank 4, with hot equipment 5, and described methane fuelled engine 1 connects respectively described recycle pump 2 and described tail gas heat exchanger 3; Described recycle pump 2 connects described tail gas heat exchanger 3; Described tail gas heat exchanger 3 connects the hot equipment 5 of described usefulness; The hot equipment 5 of described usefulness connects described buffer tank 4; Described buffer tank 4 is connected to described methane fuelled engine 1.
During work, the cooling water that buffer tank is 4 li, rely on self pressure to enter methane fuelled engine 1 by pipeline, from methane fuelled engine 1 hot water out, squeeze into tail gas heat exchanger 3 through recycle pump 2, the hot water that carries out further having improved after the sufficient heat exchange water temperature by heat conductive tube and tail gas enters with hot equipment 5.The current of buffer tank 4 are through methane fuelled engine 1; become hot water after the heat absorption; entering tail gas heat exchanger 3 further flows to hot equipment 5 after the heating again; thereby reach the waste heat that takes full advantage of cylinder sleeve of engine and outlet pipe; satisfied the requirement of national environmental protection and renewable energy utilization policy, reach turn waste into wealth, the purpose of energy-saving and emission-reduction.Can be the heating equipment of piglet insulating bed with hot equipment, also can be the animal drinking water heating equipment, can also be the heating equipment of anaerobism generator.
The utility model adopts water/exhaust-heat exchanger series connection to reclaim heat, jacket-cooling water is after exhaust gas heat exchanger further heats, make the temperature of methane fuelled engine discharging flue gas drop to 300 ℃ from about 600 ℃, nearly 60% of recoverable methane fuelled engine discharges heat, the waste heat that reclaims can be used for the intensification of mathane generating pool feed liquid, perhaps heating makes the waste heat of methane fuelled engine obtain fully recycling, reaches the purpose of energy recovery and resource reutilization.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
