Description

Utilize the power plant of internal-combustion engine high-temp waste gas as the energy

Technical field

The utility model relates to a kind of power plant, particularly a kind of power plant that utilize the internal-combustion engine high-temp waste gas as the energy, this device utilizes high-temp waste gas that internal combustion engine air vent discharges as the energy, boiler by a particular design produces high pressure steam, drive a novel steam turbine and rotate, thus the device of generation usable power.

Background technique

At present, internal-combustion engine is that the volumetric expansion that taken place when utilizing fuel combustion promotes piston and moves reciprocatingly at work, becomes to rotatablely move by connecting bar and crankshaft and does work.And the produced simultaneously heat energy that fuel combustion is expanded and done work, wherein sub-fraction is passed to body by transmission of heat, and organism temperature is raise, and most of heat then enters by outlet pipe and wastes in the atmosphere, and environment is also caused harmful effect.

Now existing gas turbine generating set uses traditional steam turbine to utilize the situation of waste gas, but does not see have same device to use on internal-combustion engine, particularly in communications and transportation, engineering machinery field, does not also find to utilize the precedent of this part heat energy at present.

The heat energy summation that a large amount of in the world internal-combustion engines is discharged from relief opening is very huge.How this part heat energy is used, in today of energy scarcity and the continuous increase of environmental deterioration pressure, meaning is very great.

In the world today, the most widely used communications and transportation, engineering machinery and the small generator field of surely belonging to of internal-combustion engine, constantly surging along with oil price, the cost that uses internal-combustion engine is also in that when the river rises the boat goes up, sometimes to bearing degree.The heat that fuel detonation produced during internal combustion engine, according to estimating action time, the part of passing to body by the heat transmission is seldom, can not surpass 30%, so, have at least 70% heat to discharge by relief opening, if this part energy is used, as long as its utilization ratio reaches 40%, so, overall energy-saving effect can reach more than 25%, and this will be very considerable.

Summary of the invention

The purpose of this utility model is, a kind of power plant that utilize the internal-combustion engine high-temp waste gas as the energy are provided, and this device can be used the internal-combustion engine high-temp waste gas.

In order to realize above-mentioned task, the utility model is taked following technical solution:

A kind of power plant that utilize the internal-combustion engine high-temp waste gas as the energy is characterized in that, this device is made up of a steam turbine and boiler; Described boiler comprises: a housing, housing has thermal insulation layer outward, center arrangement in the housing has the heat exchange chamber of heat absorption tube, the heat absorption tube top is useful on the steam chest that collection is deposited high pressure steam, and steam (vapor) outlet is arranged on the steam chest, and the below is provided with water tank, water tank is provided with water supplement port, heat exchange chamber all is connected with steam chest and water tank, and an end of heat absorption tube connects internal-combustion engine vent-pipe by pipeline, and the other end connects baffler; The admission section of steam turbine is connected with the steam ouput of boiler, and the steam discharge section of steam turbine communicates with atmosphere.

The utility model orders about the steam turbine work done owing to adopt boiler and steam turbine that internal-combustion engine high-temp waste gas heat energy utilization is got up, one side energy saving, the user cost of reduction internal-combustion engine; Reduce the harmful effect that heat that internal-combustion engine discharges causes environment on the other hand.

Fig. 2 is a steam turbine structural drawing of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing and working principle.

Embodiment

The power plant that utilize the internal-combustion engine high-temp waste gas as the energy of the present utility model comprise boiler part and steam turbine two-part.

Boiler part as shown in Figure 1, the boiler shape designs according to the structure characteristic of internal combustion engine air vent, it is little to make every effort to heat loss, the energy conversion efficiency height.Its cross section is divided into three layers, and the upper strata is a steam chest, is used for collection and deposits high pressure steam, and the top design has steam (vapor) outlet; The centre is a heat exchange chamber, is furnished with heat-absorbing water pipe, and top communicates with steam chest, and the bottom communicates with water tank; Lower floor is a water tank, and design has water supplement port on the water tank.Whole boiler appearance is wrapped up by thermal insulation layer.The front end of boiler has a tube-like interface directly to be connected with internal combustion engine air vent, and the high-temperature gas that internal-combustion engine is produced directly enters heat exchange chamber heating heat-absorbing water pipe; Also there is a tube-like interface rear end of boiler, and this tube-like interface links to each other with baffler, and the lowered waste gas of temperature is discharged from baffler.

The structure of steam turbine as shown in Figure 2,01 is impeller, its external diameter is Φ 1, on blade groove is arranged.02 is housing, and its internal diameter is Φ 2, on the admission passage is arranged, R is a blade.The admission section of steam turbine is A, and the steam discharge section is B, and C is excessive section.The eccentric setting of interior circle of impeller and housing, throw of eccentric is a, its geometrical relationship is 1/2R2=1/2R1+a.When impeller rotated in housing, the blade outer end was close in the housing slick and sly moving, slided inside and outside diametric(al) in the blade groove of impeller simultaneously, and because of impeller and the eccentric configuration of housing, impeller rotates a circle, and the distance that each blade slides into, skids off in the impeller groove is S.The admission section of steam turbine and the steam ouput of boiler join, and high pressure steam is from entering steam turbine here; The exhaust section of steam turbine communicates with atmosphere or imports the condenser dewfall is water.

Working principle of the present utility model is: after the high pressure steam that comes out from boiler enters steam turbine from the A section, the mode of action of steam turbine is had two kinds:

(1) kinetic energy that high pressure steam had with certain speed is passed to blade, makes blade promote impeller rotation acting, and this mode is identical with traditional steam turbine.

(2) pressure of high pressure steam is passed to blade, makes blade become a piston in the C district and promotes impeller rotation acting, and this mode is identical with traditional steam-cylinder piston.

When steam turbine is worked, above-mentioned dual mode works simultaneously, the utility model utilizes the power plant of internal-combustion engine high-temp waste gas as the energy, traditional steam turbine and steam-cylinder piston are combined dexterously, can be effectively the high-temp waste gas of internal-combustion engine be converted into high pressure steam, as the power source of steam turbine, reduced the user cost of internal-combustion engine; Reduced the harmful effect that heat that internal-combustion engine discharges causes environment.
