1a,1b : 개수로, 2 : 발전기,1a, 1b: in number, 2: generator,

3 : 수차, 4 : 개수로의 오리피스 부분.3: aberration, 4: orifice part in the channel.

본 발명은 화력 및 원자력 발전소의 복수기에 냉각수를 공급하는 순환수의 개수로와 방출수의 개수로에 설치되어 순환수와 방출수의 유속과 유량을 이용하여 전기를 생산할 수 있는 개수로의 순환수 및 방출수를 이용한 발전장치에 관한 것이다.The present invention is installed in the circulating water channel and the discharge water channel for supplying the cooling water to the condenser of the thermal power plant and nuclear power plant, the circulating water in the channel to produce electricity using the flow rate and flow rate of the circulating water and discharge water And a power generation device using discharged water.

주지된 바와 같이 화력 및 원자력 발전소에서는 복수기로 냉각용 순환수를 공급하고, 이 복수기 냉각에 사용된 순환수는 단순히 복수기 냉각용으로 복수기를 통과한 후 방수로를 통하여 바다와 같은 외부로 방출된다.As is well known, the thermal power and nuclear power plants supply the circulating water for cooling to the condenser, and the circulating water used for the condenser cooling simply passes through the condenser for cooling the condenser, and then is discharged to the outside such as the sea through the waterproof passage.

즉 복수기 냉각용 순환수는 발전 호기당 개수로를 통하여 유입되는바, 예를 들어 펌프로 다량의 바닷물을 펌핑하여 개수로를 통하여 복수기에 공급되고, 복수기를 냉각시킨 순환수는 방수로를 통하여 다시 바다로 되돌려 보내지도록 되어 있다.That is, the circulator water for cooling the condenser is introduced through the channel per power generation unit. For example, a large amount of sea water is pumped into the condenser and supplied to the condenser through the conduit. It is supposed to be sent back.

이와 같이 종래에는 화력 및 원자력 발전의 개수로를 통해 유입되는 다량의 복수기 냉각용 순환수는 단순히 복수기 냉각용으로 복수기를 통과한 다음, 방수로를 통하여 그대로 방류됨에 따라 다량의 순환수 및 방출수의 유량과 유속 에너지를 회수하지 못하였다.As described above, a plurality of condenser cooling circulation water introduced through a thermal and nuclear power plant channel simply passes through the condenser for condenser cooling, and is discharged as it is through a waterproof passage, so that a large amount of circulating water and discharged water flow. Overflow energy could not be recovered.

이에 본 발명은 종래 상기와 같은 문제점을 감안하여 발명된 것으로, 화력 및 원자력 발전소의 복수기 냉각용 순환수와 방출수의 유량과 유속을 이용하여 전기를 생산할 수 있는 개수로의 순환수 및 방출수를 이용한 발전장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented in view of the above-described problems, and uses the flow rate and flow rate of the circulating water for cooling the condenser and the discharged water of the thermal power plant and nuclear power plant, and the circulating water and the discharged water in the number to generate electricity. The purpose is to provide a power generator used.

상기와 같은 목적을 달성하기 위한 본 발명은 일정한 폭을 가진 순환수 유입용 개수로와 일정한 폭을 가진 방출수 배출용 개수로에 발전기를 가진 수차를 각각 설치하되, 상기 수차는 개수로의 폭과 단면적의 약 1/2을 형성하는 오리피스 부분에 설치한 구조로 되어 있다.In order to achieve the above object, the present invention is to install aberrations having a generator in the circulating water inlet channel having a constant width and discharge water discharge channel having a constant width, respectively, the aberration and the width of the channel It is a structure provided in the orifice part which forms about 1/2 of cross-sectional area.

이하, 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명이 적용된 개수로의 순환수 및 방출수 개수로를 나타낸 개략 구성도이다.1 is a schematic configuration diagram showing the circulation water and the discharge water channel to the channel to which the present invention is applied.

본 발명은 일정한 폭(W)을 가진 순환수 유입용 개수로(1a)와 일정한 폭(W)을 가진 방출수 배출용 개수로(1b)에 발전기(2)를 갖춘 수차(3)를 각각 설치하되, 상기 수차(3)들은 개수로(1a,1b)의 폭(W)과 단면적(S)의 약 1/2를 형성하는 개수로의 오리피스 부분(4)에 설치하여 이루어진 구조로 되어 있다.According to the present invention, a water wheel (3) having a generator (2) is installed in each of the circulating water inflow channel (1a) having a constant width (W) and the discharge water discharge channel (1b) having a constant width (W), respectively. However, the aberrations 3 have a structure in which the aberrations 3 are provided in the orifice portion 4 of the channel to form about half of the width W and the cross-sectional area S of the channels 1a and 1b.

즉 본 발명은 화력 및 원자력 발전소의 복수기 냉각용 순환수와 방출수를 유도 안내하는 각각의 개수로(1a,1b)에 수차(3)를 설치하였는데, 이 발전용 수차(3)는 해당 개수로(1a,1b) 유량과 유속이 변하는 지점인 개수로의 오리피스 부분(4)에 설치되어 있다.That is, according to the present invention, the aberration 3 is installed in each channel 1a and 1b for guiding the circulating water and the discharge water for the condenser cooling of the thermal power plant and the nuclear power plant. (1a, 1b) It is provided in the orifice part 4 of the channel which is a point where a flow volume and a flow velocity change.

여기서 상기 개수로의 오리피스 부분(4)은 개수로(1a,1b)에 흐르는 순환수와 방출수의 유량과 유속이 변하는 지점으로 상기 개수로(1a,1b)들의 입구 및 출구 쪽의 유량과 속도 변화없이 냉각수를 공급 및 방출시키면서 이 개수로의 오리피스 부분(4)에 형성된 단면적과 폭이 작은 1/2 지점에서 수차(3)를 이용하여 발전하도록 되어 있다.Here, the orifice portion 4 of the channel is a point where the flow rate and the flow rate of the circulating water and the discharged water flowing in the channel 1a, 1b are changed, and the flow rate and the velocity at the inlet and the outlet of the channel 1a, 1b. The power is generated using the aberration 3 at the half point where the cross-sectional area and the width formed in the orifice portion 4 of this channel are small while supplying and discharging the cooling water without change.

공지된 바와 같이 발전기(2)의 출력(P) = 9.8×Q×H×ηt× ηg에서 베르누이 정리 H+P/W+V2/2g=K(일정)의 식을 적용하면, H=0, P/W=0일 경우, H(위치수도) 대신에 속도수두(V2/2g)를 대입하면, 상기 발전기(2)의 출력(P)=9.8×Q×V2/2g×ηt×ηg 식에 의하여 발전출력을 얻을 수 있다(여기서, ηt:수차효율, ηg:발전기 효 율, H:위치수도, P:압력수도, V:개수로의 유속, g:중력이다).The output of the generator (2) as is known in the art (P) = 9.8 × Q × H × From the ηt × ηg applying expression of Bernoulli H + P / W + V 2 / 2g = K ( constant), H = 0 When P / W = 0, the speed head (V 2 / 2g) is substituted for H (positional water), and the output (P) of the generator 2 = 9.8 × Q × V 2 / 2g × ηt × The power generation output can be obtained by the equation ηg (where ηt: aberration efficiency, ηg: generator efficiency, H: position water, P: pressure water, V: channel flow rate, and g: gravity).

일예로, 본원 발명의 개수로(1a,1b)의 전후 부근인 (가), (나)지점에서 순환수 및 방출수의 유속이 2m이면, 상기 개수로의 오리피스 부분(4)은 유속이 4m정도 유지되기 때문에 이 유속을 이용하여 수차(3)를 돌려 발전기(2)로 발전할 수가 있다.For example, if the flow rate of the circulating water and the discharged water is 2 m at the points (a) and (b) near the front and rear of the channels 1a and 1b of the present invention, the orifice portion 4 of the channels is 4m. Since the accuracy is maintained, it is possible to generate the generator 2 by turning the aberration 3 using this flow rate.

상기와 같이 본 발명에 따른 개수로의 순환수 및 방출수를 이용한 발전장치를 순환수 및 방출수가 유출입되는 개수로의 일정부분에 단면적과 폭이 약 1/2폭으로 줄어드는 개수로의 오리피스 부분(4)을 만들고, 이 목부분에 수차를 이용하여 유속 에너지를 발전 에너지로 회수할 수 있는 효과를 가진다.As described above, the orifice portion of the power generation device using the circulation water and the discharge water in the channel according to the present invention has a cross-sectional area and a width reduced to about 1/2 width in a predetermined portion of the channel through which the circulation water and the discharge water flow in and out ( 4) and the aberration is used to recover the flow rate energy as power generation energy.
