Description of drawings
Fig. 1 is the structural drawing according to a kind of Decomposition Cycle water electricity generating device of the present utility model.
Embodiment
The Decomposition Cycle water electricity generating device that the utility model proposes, accompanying drawings is as follows.
As shown in Figure 1, prong 7 on return pipe 1 and before being positioned at flow control valve 2 front end places and opening, rear end is opened a back prong 8, is that preceding prong 7 is higher than back prong 8, and bigger drop is preferably arranged between the two.Increase by a bypass between preceding prong 7 and back prong 8, water turbine 4 is installed in the bypass, it is by the bypass water pipe at prong 7 places before introducing valve 5 and slip joint 6 and being connected to, and is connected to the bypass water pipe at prong 8 places, back by drawing valve 3.Introduce valve 5 thereby the past of the circulating water in the return pipe 1 prong 7 is driven water turbine 4 actings through slip joint 6 oblique introducing water turbine 4, drawing valve 3 draws the water in the water turbine 4 again and gets back in the return pipe 1 of back behind the prong 8, at this moment, flow control valve 2 is in closed condition.
The hydraulic generator unit is installed in return pipe 1 below; utilize water turbine 4 actings to generate electricity; can be according to the hydraulic generator unit of the concrete landform design arrangement of user; the hydraulic turbine generator assembly has the Comprehensive Control screen; design has automatic synchronizing paralleling device and tripping operation to drop into water resistance protective gear, the full-time guard of the personnel that need not automatically.When water turbine 4 or hydraulic generator unit break down, close and introduce valve 5 and draw valve 3, open flow control valve 2 and get final product, do not influence original production like this.
Wherein, water turbine 4 design discharges are the water pump rated flow 1600m of former Decomposition Cycle water device
3/ h=0.44m
3/ s, according to the concrete topographical elevation difference and the circulation situation of decomposing, available head is about 28 to 35 meters according to a preliminary estimate, may be higher, every water return pipeline can be adorned 100kw hydraulic generator unit one cover.Generator is 380 volts of three-phases, directly incorporates our factory's electrical network into.
Summer is during the highest temperature, about 28 meters of head, flow 1600m
3/ h, the 86kw that can generate electricity, ordinary circumstance can be utilized the water pump lift of having more than needed, about 35 meters of head, flow 1500m
3/ h, 100kw can generate electricity.
Winter discharge 700m
3/ h, about 25kw can generate electricity.
Produce in the alumina producing factory test of producing 1000000 tons per year, it in order to the illumination of full factory, has saved the electric power spending at the Decomposition Cycle Decomposition Cycle water electricity generating device that installs additional waterborne.
Fully invested needs about 300,000 yuan of fund altogether, wherein:
240,000 yuan in hydraulic generator unit 1 cover;
15 meters in water pipe, 1 about 40,000 yuan of 3 on valve and slip joints;
10,000 yuan of installation fees;
10,000 yuan of board-like factory building 10 square meters and monitoring camera-shooting equipment meters.
Put into operation the back by 90kw calculating, and 90 degree that promptly per hour generate electricity calculate by 0.45 yuan/degree, move 250 days in 1 year, ten thousand yuan of the income of can generating electricity 90 * 24 * 250 * 0.45=34.
Invest return period less than 1 year, economic benefit is considerable.
Above mode of execution only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
