【発明の詳細な説明】
本発明は、総熱量を利用した発電装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power generation device that utilizes total heat.
従来、エンジンに発電機が連結された発電装置では、排
気ガスに含まれる熱は大気中に放出されるか、また大気
に放出されずに冷却水を温めるようにしたものでも、そ
の温められた冷却水はその温度が負荷の変動で変化する
ために温められた冷却水を利用しにくく、結局、従来の
発電装置では、エンジンで発生した熱の有効利用は非常
に少なかった。Conventionally, in power generation systems in which a generator is connected to the engine, the heat contained in the exhaust gas is either released into the atmosphere, or even if it is designed to warm the cooling water without being released into the atmosphere, the heat contained in the exhaust gas is released into the atmosphere. Because the temperature of cooling water changes with load fluctuations, it is difficult to utilize heated cooling water, and as a result, in conventional power generation systems, the effective use of heat generated by the engine is extremely limited.
本発明は、上記の点を考慮して、温水タンクの温水でエ

うにして、エンジンの総熱量を利用した発電装置を提供
するものである。In consideration of the above points, the present invention cools the engine with hot water in a hot water tank, heats this hot water with exhaust gas from the engine, and further cools the engine when the load is below a predetermined load or when the hot water reaches a certain temperature. At the following times, electric power is supplied from a generator connected to the engine to a heater provided in the hot water, thereby providing a power generation device that utilizes the total heat amount of the engine.
以下、図面により実施例を詳細に説明する。Hereinafter, embodiments will be described in detail with reference to the drawings.

。The figure shows one embodiment of the present invention, where 1 is an engine, 2 is a generator, 3 is a switchboard, and 4 is a hot water tank.The switchboard 3 is provided with a load detector 5, and the hot water tank 4
is provided with an exhaust heat exchanger 6, an electric heater 7, a temperature detector 8, a high temperature overflow valve 9, and a constant water level valve 10.

し、また第２の電磁スイッチ１２は配電盤３の主回路に
接続された負荷が予め定めた値以上になった時、配電盤
３からの電力を遮断する。Further, a part of the electric power from the switchboard 3 is supplied to the electric heater γ via the first and second electromagnetic switches 11. When the load exceeds a predetermined value, the second electromagnetic switch 12 shuts off the power from the switchboard 3 when the load connected to the main circuit of the switchboard 3 exceeds a predetermined value. Cut off.
また発電機２で発電された電力は配電盤３を介して主回
路に供給され、温水タンク４からの温水はエンジン１を
冷却して温水タンク４に戻され、エンジン１からの排気
ガスは排気熱交換器６で温水タンク内の温水を加熱した
後、排気される。Furthermore, the electric power generated by the generator 2 is supplied to the main circuit via the switchboard 3, the hot water from the hot water tank 4 cools the engine 1 and is returned to the hot water tank 4, and the exhaust gas from the engine 1 is supplied with exhaust heat. After the hot water in the hot water tank is heated by the exchanger 6, it is exhausted.
次に、本実施例の動作を説明する。Next, the operation of this embodiment will be explained.
まず、低負荷時に温水を利用する場合は、配電盤３に設
けられた負荷検出器５は負荷が予め定めた値以下である
ので、電磁スイッチ１２は電力を供給するようにオンに
なっている。First, when hot water is used during low load, the load detector 5 provided on the switchboard 3 indicates that the load is below a predetermined value, so the electromagnetic switch 12 is turned on to supply power.
しかし、温度検出器８が温水タンク４内の温水の温度を
予め定めた温度以上であることを検出しているので、電
磁スイッチ１１はオフの状態になって電気ヒータ７に電
力を供給しない。However, since the temperature detector 8 detects that the temperature of the hot water in the hot water tank 4 is higher than the predetermined temperature, the electromagnetic switch 11 is turned off and does not supply power to the electric heater 7.
従って、その状態で温水を利用すると、定水位弁１０が
作動して、温水利用で減水した分だけ冷水が供給される
。Therefore, when hot water is used in this state, the constant water level valve 10 is activated and cold water is supplied by the amount of water reduced by using hot water.
ここで、温水タンク４内の温水が予め定めた温度より低
くなった場合には、電磁スイッチ１１が作動し、電気ヒ
ータ７で温水が加熱され、一定温度に温められて利用さ
れる。Here, when the temperature of the hot water in the hot water tank 4 becomes lower than a predetermined temperature, the electromagnetic switch 11 is activated, the hot water is heated by the electric heater 7, and is heated to a constant temperature for use.
次に、低負荷で温水が利用されない場合は、定水位弁１
０で温水タンク内の水位は一定になっているが、温水の
温度が高い時、電磁スイッチ１１はオフで、温水は加熱
されない。Next, when hot water is not used under low load, constant water level valve 1
At 0, the water level in the hot water tank is constant, but when the temperature of the hot water is high, the electromagnetic switch 11 is off and the hot water is not heated.
ここで、温水の温度が低くなった時、電磁スイッチ１１
が作動して電気ヒータ７で温水を加熱し、一定温度に保
持する。Here, when the temperature of the hot water becomes low, the electromagnetic switch 11
is activated, the electric heater 7 heats the hot water and maintains it at a constant temperature.
一般に、エンジンを低負荷で、長時間連続運転すること
は、燃焼状態が悪く、内部にカーボンが付着してエンジ
ンのためによくない。In general, continuous operation of an engine at low load for long periods of time causes poor combustion conditions and builds up carbon inside the engine, which is not good for the engine.
しかし、上記のようにすることによって、ヒータの分だ
け負荷が増加し、低負荷の状態がまぬがれるという利点
がある。However, by doing as described above, the load increases by the amount of the heater, and there is an advantage that a low load state can be avoided.
また、高負荷の時に温水を利用した場合は温水が減るの
で、定水位弁１０が作動し、冷水が温水タンク４に供給
され、また温度検出器８は高い温度を検出し、負荷検出
器５は高負荷を検出しているので、電磁スイッチ１１，
１２は動作しない。In addition, when hot water is used at a time of high load, the amount of hot water decreases, so the constant water level valve 10 operates, cold water is supplied to the hot water tank 4, and the temperature detector 8 detects a high temperature, and the load detector 5 detects a high load, so the electromagnetic switch 11,
12 does not work.
高負荷で温水の使用がない場合は高温オーバーフロー弁
９が作動し、高温水を排出し、定水位弁１０より冷水を
補給して冷却水温を一定に保持する。When the load is high and hot water is not used, the high temperature overflow valve 9 operates to discharge the high temperature water and replenish cold water from the constant water level valve 10 to maintain the cooling water temperature constant.
なお、エンジンの冷却水温以上の高温水をを利用したい
場合は、温水タンク４からの温水を電気ヒータや他の加
熱器等により加熱すればよい。Note that if it is desired to use high-temperature water that is higher than the engine cooling water temperature, the hot water from the hot water tank 4 may be heated with an electric heater or other heater.
本実施例は、以上のように構成したので、温水の形でエ
ネルギーを保存することができ、温水の温度を略々一定
にすることができるので、温水の利用および制御が容易
であり、また主回路が低負荷でエンジンの発熱、排気熱
が少なくても、水温を所望の温度にすることができ、更
に、低負荷時でもエンジンはある一定温度の温水で冷却
即ち恒温冷却されるので、シリンダの酸化腐蝕を防止で
き、エンジンの不調を防止し、また温水タンクの容量を
選ぶことにより、温水のオーバーフローを防止すること
も可能で、熱効率を高め、またエンジンの超低負荷を防
止することもできる。Since this embodiment is configured as described above, energy can be stored in the form of hot water, and the temperature of the hot water can be kept approximately constant, making it easy to use and control the hot water. Even when the main circuit is under low load and there is little engine heat or exhaust heat, the water temperature can be maintained at the desired temperature.Furthermore, even when the load is low, the engine is cooled with hot water at a certain temperature, that is, isothermally cooled. It can prevent oxidation corrosion of the cylinder, prevent engine malfunction, and by selecting the capacity of the hot water tank, it is also possible to prevent hot water from overflowing, increasing thermal efficiency and preventing extremely low engine loads. You can also do it.
以上説明したように、本発明によれば、エンジンから出

率の高い発電装置を提供できる利点がある。As described above, according to the present invention, the total amount of heat emitted from the engine can be effectively utilized, so there is an advantage that a power generation device with high thermal efficiency can be provided.
