Abstract
The utility model discloses a heat exchange type water turbine which comprises a water inlet volute and an impeller seat, wherein a heat exchange device is arranged between the water inlet volute and the impeller seat; the water inlet volute is communicated with the impeller seat through the heat exchange device; and the heat exchange device comprises a plurality of heat exchange tubes. The heat exchange type water turbine has the advantages as follows: the structure is reasonable, the size is small, the heat exchange tubes are added between impellers of the water turbine and the water inlet volute, and the wind resistance is reduced, so that power required by fan blades on the water turbine is reduced correspondingly. Hot air can radiate heat uniformly, and the heat exchange effect is good.
Description
Technical field
Relate to a kind of band heat exchange-type water turbine, particularly a kind of high efficient heat exchanging formula water turbine.
Background technique
Water turbine is to be the transformation of energy of current the dynamic power machine of rotating mechanical energy, and it belongs to the turbomachinery in the fluid machinery.Water turbine can be divided into impulse turbine and reaction turbine two big classes by working principle.The runner of impulse turbine is subjected to the impact of current and rotates, and the pressure of current is constant in the working procedure, mainly is the conversion of kinetic energy; The runner of reaction turbine is subjected to the reaction force of current and rotates in water, the pressure of current energy and kinetic energy all change in the working procedure, but mainly is the conversion of pressure energy.
But the heat exchange windage that existing water turbine causes because the water turbine volume is big is also big, so the heat exchange weak effect designs the little and high-power water turbine of a kind of volume and be the difficult problem in the design.
The model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide the little and high-power high efficient heat exchanging formula of a kind of volume water turbine.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of heat exchange-type water turbine, comprise into water spiral case and impeller base, be provided with heat-exchanger rig between described water inlet spiral case and impeller base, described water inlet spiral case is communicated with described impeller base by described heat-exchanger rig.
Further, described heat-exchanger rig comprises many heat exchanging tubes.
Working principle of the present utility model: cooling water is in entering the hydraulic turbine operation process, earlier through heat exchanging tube and then the work of promotion turbine impeller.
In order to make more reasonable structure, an end of every described heat exchanging tube is located on the inside portion of described water inlet spiral case, the other end is connected on the described impeller base.
In order to make the hot gas heat radiation evenly, all heat exchanging tubes evenly distribute.
Beneficial effect: compared with prior art, the utility model has the advantages that: rational in infrastructure, volume is little, owing to increase heat exchanging tube between turbine impeller and the water inlet spiral case, windage reduces, so required corresponding the reducing of power of the fan blade on the water turbine.The hot gas heat radiation is even, good effect of heat exchange.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of high efficient heat exchanging formula of the utility model water turbine, comprise into water spiral case 1, heat-exchanger rig and impeller base 3, in impeller base 3, be provided with impeller, rotatingshaft, impeller is installed on the rotatingshaft, top at rotatingshaft is connected with fan blade, above-mentioned heat-exchanger rig is made up of 18 heat exchanging tubes 2, all heat exchanging tubes 2 are evenly distributed on between the water spiral case 1 and impeller base 3, and an end of every heat exchanging tube 2 is connected on the inside portion of described water inlet spiral case 1, the other end is connected on the impeller base 3, so just can be communicated with impeller base 3 by heat exchanging tube 2 spiral case 1 of will intaking.The radical of heat exchanging tube can be adjusted according to actual needs in the utility model.
During use, cooling water enters water turbine by the import of water inlet spiral case 1, then in the hydraulic turbine operation process, spiral case 1 has been communicated with impeller base 3 because heat exchanging tube 2 will be intake, water is just earlier through heat exchanging tube 2, and then promotion impeller rotation, thereby drive the fan blade rotation, cooling water is got back to cooling tower filler through behind the water turbine like this, in this process, because having produced air, the rotation of the fan blade above the water turbine flows, water in heat exchanging tube flows some heat take away to flow air, cooling water is flowing to behind heat exchanging tube in the turbine impeller seat process then, and return in the cooling tower filler process, along with rotate producing wind, fan blade takes away heat in the cooling water.
The above, only being preferred embodiment of the present invention, is not that the present invention is done any pro forma restriction, and every foundation technology of the present invention is implemented above embodiment is made any simple modification, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
