Description

Generation of electric power small heat annexation boiler combined}

The present invention allows the use of hot water by heating the water using the heat source and waste heat of the exhaust gas obtained during the explosion and combustion of the engine, and compact heat merging to obtain auxiliary energy by installing a generator on the rotating shaft of the engine that is idle. More specifically, it relates to a boiler and a power generation device, and more specifically, to directly supply the supplied water to a primary heating tank at the rear end of the exhaust pipe using heat of exhaust gas, and branch the heated water into a secondary heating tank and a water cooling jacket at the end of the exhaust pipe. By supplying secondary heating, it can be used as hot water or for heating, so that it can be reused by absorbing the heat energy that is unnecessarily dissipated or discarded through the exhaust pipe as much as possible and saving energy accordingly. Always supply warm air to burn and explode In addition, when not used as a boiler, the supply of direct water is stopped and the internal water is cooled and circulated to be used as a general engine. To a small heat coalition boiler and a power plant.

In general, the engine linearly reciprocates the piston with energy obtained in the process of cylinder intake, compression, explosion, and exhaust, and this reciprocating motion converts the crank rotational axis into rotational motion through the connecting rod, thereby driving the machine by using the rotational force. The boiler for heating the water used for heating or bathrooms is a furnace boiler, an associated boiler, an furnace boiler, an upright boiler, a water pipe according to the structure of a device for generating steam, a main body, a combustion device and an auxiliary device. It is well known that water, which is classified as a boiler, is used to directly heat water circulated in a pipe as heat generated by combustion of fuel.

However, such a conventional engine has been manufactured and used to construct a power source by rotating the crankshaft by the reciprocating motion of the piston through combustion of the fuel, or separately configured to supply hot water by heating water with the combustion heat of the fuel. For example, in the case of electricity, there is a drawback that the energy efficiency is lowered compared to the fuel consumption by simply burning a lot of fuel to obtain and use only a crankshaft power source.

On the other hand, the boiler is installed by winding a water pipe capable of circulating water along the pipe in the combustion chamber inside the boiler body, and installs a burner on one side and a communication on the other side, thereby igniting the burner in the combustion chamber inside the body. As the fuel is burned and heated, the water pipe circulated by the heat of combustion is heated to supply hot water for heating or bathroom. The conventional boiler is a fuel that is injected by cooling the combustion chamber of the boiler body during initial ignition. It was not completely burned and was discharged directly to the unburned state, which was the main cause of air pollution. In addition, even after heating in the pre-heated state, the injected fuel is burned to heat only the water pipes, and then, as it is directly discharged into the atmosphere as a high temperature through the communication, a loss of heating energy is large compared to the combustion amount of the fuel. Caused. In addition, the boiler was limited to the function of heating the water of the water pipe wound therein by burning the fuel supplied into the combustion chamber and there was no configuration capable of realizing separate energy generation.

The present invention has been made to solve the above-mentioned conventional drawbacks and problems, the main object of the present invention is that the water supplied to the hot water primarily by using the exhaust gas heat energy emitted through the exhaust pipe of the engine The heated water is reheated in the water cooling jacket and the secondary heating tank of the engine to supply hot water, and heated air by heat energy emitted from the engine and the primary and secondary heating tanks is provided through the air filter. It is intended to provide a combined heat generation boiler combined power plant to eliminate the noise pollution by completely blocking the noise generated by the engine to be completely burned together with the fuel.

Another object of the present invention is to provide a generator combined with a combined heat boiler for generating a separate power or electrical energy through the generator is built on the crank rotation shaft idle when the engine is operating.

Still another object of the present invention is to provide a combined power generation unit for a combined heat boiler for facilitating the cleaning of the exhaust pipe and the primary and secondary heating tanks by forming a washing water supply pipe through which the washing water is supplied to the tip end of the exhaust pipe.

On the other hand, the catalyst 15 is connected to the front end of the exhaust pipe 7 between the primary and secondary heating tanks 9 and 8 in a detachable state.

At this time, in the interior of the secondary heating tank 8 and the primary heating tank 9, the honeycomb heat sink 9a is arranged in several layers so as to circulate the drain in order to increase the heating surface area of the supplied water, and the air filter 4 Heated air introduced through the) is to be forcibly supplied to the intake valve (3) by the intercooler (5), the spiral guide portion (5a) is installed in the inlet end of the intake valve (3) to quickly suck the heated air do.

On the one side of the primary heating tank (9) through which the exhaust pipe (7) is passed, a direct water supply pipe (16) is installed in communication with the honeycomb heat sink (9a) arranged in several layers inside the primary heating tank (9). The drain pipe 17 is installed in communication with the other side so that the supplied water is first heated to be supplied to the radiator 2, and at one point of the drain pipe 17, it is easy to control the supply or blocking of water. The valve 18 is installed so that the branch supply pipe 20 is connected to the other side of the radiator 2 so that the water supplied by the primary heating is branched to the water cooling jacket 19 and the secondary heating tank 8. On the other side of the secondary heating tank 8 and the water cooling jacket 19, a pump 22 for mixing hot water heated from the engine 1 and the exhaust pipe 7 respectively and forcibly draining it to the radiator 2 is installed.

According to the valve 25 is installed to selectively supply or shut off the water supplied to the radiator (2).

At this time, the condensation water discharge pipe 31 which is opened and closed by the operation of the valve is installed in the lower portion of the primary heating tank (9) to extend the life of the primary heating tank (9) to be drained from time to time when condensation occurs.

In addition, a generator 26 is installed on the crank rotation shaft of the engine 1 so as to obtain separate electric energy, and the engine 1 and the air filter 4 or the primary and secondary heating tanks 9 and 8 are provided. The case 27 is covered to block noise and heat radiated to the outside, and a noise blocking material 28 is attached to an inner surface of the case 27, and a plurality of points of the case 27 lack internal air. A plurality of inlet holes (29) are formed so that outside air as much as the lack of air flows in.

In particular, it is formed so that the warm air inside the case 27 is not discharged, the air filter 4 is located inside the case 27, the engine (1) and the primary and secondary heating tanks (9) (8), etc. Heated hot air is sucked in to further increase the combustion efficiency and reduce the generation of soot due to unburned.

According to the present invention configured as described above, while the fuel is supplied into the combustion chamber of the engine 1 and the air sucked into the air filter 4 is introduced into the combustion chamber by the intercooler 5 and ignited, as in a general engine, suction, compression, When the explosion and exhaust stroke are repeatedly operated, the piston inside the combustion chamber reciprocates and the connecting rod connected thereto rotates the crank rotation shaft, and the suction air sucked into the suction valve 3 is discharged from the intercooler 5. It is introduced more strongly by the operation, which is guided through the spiral guide portion 5a and sucked into the suction valve 3 to induce powerful air transfer, and the exhaust gas is atmospheric by the operation of the turbine 11. It is quickly discharged to the middle to obtain a strong power of the engine (1).

When the engine 1 operated as described above is to be used as a boiler for hot water supply or heating, as shown in FIG. 5, first, the valve 25 mounted below the pump 22 of the mixing drain pipe 21 and The pump 22 in a state in which the valve installed at the condensation water discharge pipe 31 is completely shut off and the valve 18 mounted at the drain pipe 17 and the valve 24 mounted at the tip of the hot water pipe 23 are opened. When the water is supplied, the water supplied through the direct water supply pipe 16 is primarily heat-exchanged and heated in the honeycomb heat sink 9a arranged in several layers inside the primary heating tank 9, and the heated water is drained. The water circulated to the radiator 2 through the 17 and circulated to the radiator 2 is circulated to the water cooling jacket 19 and the secondary heating tank 8 of the engine 1 and the heat of explosion and the exhaust pipe of the engine 1. Branched water is heated by exhaust heat exhausted to (7), and this branched and heated water is mixed with a drain pipe (21). The cold water supplied to the primary heating tank (9) through the direct water supply pipe (16) is sequentially arranged in several layers inside the primary heating tank (1). The exhaust heat is absorbed to a large area by the exhaust gas heat released into the atmosphere from the surface of the heat sink 9a and is primarily heated. The water heated in the primary heating tank 7 is forced by the operation of the pump 22. It is supplied to the radiator 2 through the drain pipe 17.

Shut off the valve 14 installed in front of the turbine 11 and supply the washing water through the washing water supply pipe 12 formed at the end of the exhaust pipe 7 to open the exhaust pipe and the primary and secondary heating tanks 9 and 8 formed at the front end thereof. Wash. Subsequently, when the washing is completed, the valve 13 of the washing water supply pipe 12 is shut off, the valve 14 installed in front of the tub 11 is opened, and the engine 1 is driven to wash the residue water by exhaust gas. As the exhaust pipe 7 and the first and second heating tanks are completely discharged to the outside, the user completes the cleaning of the inside of the exhaust pipes 7 and the first and second heating tanks. In addition, since the exhaust gas discharged from the engine 1 is completely burned by the heater 10 installed at the tip of the exhaust pipe 7, there is no smoke of the gas discharged into the atmosphere. The condensation water discharge pipe 31 installed through the primary heating tank 9 opens and closes the valve from time to time to completely remove the condensation water therein.

As described above, in the boiler combined power generation apparatus of the present invention, the water supplied to the direct water supply pipe is primarily heated in the primary heating tank by using the thermal energy emitted through the exhaust pipe, and the heated water is supplied to the water cooling jacket and the secondary of the engine.
