Description
Technical field
The utility model relates to a kind of marine diesel engine tail gas energy and loops back receiving apparatus, can be applicable in marine ships diesel engine.
Background technique
In the energy that traditional boat diesel engine does not have to utilize in its working procedure, the waste gas of its main frame discharge has comprised a large amount of energy, has reached fuel combustion and has produced 25.5% of total energy.We are also very low to the utilization of this part energy at present, have caused energy dissipation to a great extent.Although marine diesel engine has been brought into use turbo charge system at present,, waste gas, after turbo charge system, still has higher heat, and this part waste gas is directly discharged to the external world, true unfortunate.If this part energy can be utilized, will improve so undoubtedly energy utilization rate, reduce discharge thereby reduce energy consumption.
Model utility content
The purpose of this utility model is to overcome existing the problems referred to above in prior art, and a kind of reasonable in design is provided, and marine diesel engine tail gas energies convenient, energy-saving and environmental protection loop back receiving apparatus.
The utility model solves the problems of the technologies described above adopted technological scheme: this marine diesel engine tail gas energy loops back receiving apparatus, include diesel engine, the outlet pipe matching with it, it is characterized in that, also include heat-collection water tank, intake pipe, waste pipe, inlet valve, drain valve, circulating pipe, suction booster, drive turbine and generator, described outlet pipe is placed in heat-collection water tank, on described heat-collection water tank, have pore, top and the intake pipe of this heat-collection water tank are connected, bottom and the waste pipe of heat-collection water tank are connected, between described intake pipe and waste pipe, be connected by circulating pipe, on the feed-water end of described intake pipe, inlet valve is installed, in the discharge ends of described waste pipe, drain valve is installed, one section of outlet pipe between described diesel engine and heat-collection water tank is provided with driving turbine, described driving turbine and generator are in transmission connection.
As preferably, on described circulating pipe, suction booster is installed.
As preferably, described outlet pipe is folding shape coil pipe.
The beneficial effects of the utility model are: this product can reduce energy consumption, collect waste heat, the heat of simultaneously collecting can feedback diesel engine, the ship particularly navigating by water at sea, under microthermal climate, may make diesel powered output unstable, and adopt this device can reach minimizing oil consumption, and increase power, make power export object stably.
