Description

Power generator using high pressure {Power producer for high pressure}

The present invention relates to a power generating device to obtain a driving force by the eccentric rotation of the piston by high pressure.

A power generator for obtaining propulsion by eccentric rotation of a piston by high pressure has already been provided through Patent Publication No. 87-7348.

This produces a high pressure combustion gas using an air compressor and a fuel compression pump, and the generated combustion gas is mixed with the steam of the boiler installed around the combustor before being introduced into the engine body having an eccentric piston from the combustor. It is configured to lower the temperature.

Therefore, the cooling can be effectively performed by the steam mixed with the combustion gas, but the heat loss is reduced as much as it is cooled, so the thermal efficiency is low, the fuel is excessively required, and various harmful gases are generated due to incomplete combustion by moisture, especially the mixed gas. It is pointed out that problems such as a large propulsion force cannot be obtained because the power is obtained only by compression.

The present invention is to provide a power generator using a high pressure that can maximize the thermal efficiency with a low fuel cost, can expect a complete combustion, and can double the propulsion force compared to the fuel cost in order to solve the above-mentioned problems.

In order to achieve the above object, the present invention allows the combustion gas to be cooled by heat exchange of a cooling tube passing through the inside of the combustor to obtain propulsion by the Brayton Cycle, and also to the steam converted during the heat exchange with the combustion gas. Characterized in that configured to obtain a driving force by the Rankine cycle (Rankine Cycle).

It is desirable to allow forced convection within).

Rapid convection by the impeller 14 can reduce the length of the cooling pipe 10 for the combustion chamber by rapid heating, so it is suitable for the vehicle application.

3 is a cross-sectional configuration diagram of the engine main body used in the present invention, the engine main body 8 is connected to the exhaust pipe of the combustor 6, and the engine main body 12 connected to the outlet of the cooling pipe 10 Although divided into the same structure, the piston 24 is installed eccentrically connected to the cylinder 20 having the inlet pipe 16 and the exhaust pipe 18, and the propulsion shaft 22 passing through the inner working chamber of the cylinder 20 And a partition plate which is elastically installed between the suction pipe 16 and the exhaust pipe 18 of the cylinder 20 by a spring 26 and whose sealing portion 28 is in sliding contact with the piston 24 to define the compression chamber and the discharge chamber. It consists of 30.

The suction pipe 16 of the cylinder 20 is provided with an opening / closing plate 32 controlled by a controller to maintain atmospheric pressure during exhaust and is connected to the exhaust pipe of the combustor 6 or the discharge pipe of the cooling pipe 10.

The piston 24 is composed of a sealing ring 38 having a plurality of bearings 36 between the main body 34 and the main body 34, which are connected to the propulsion shaft 22, thereby allowing independent rotation of the main body and the sealing ring. Configure it to be possible.

However, the engine main body operated by the combustion gas of the two engine main body of the present invention may use a gas turbine of a general structure, so the two engines operated by the steam generated during the heat exchange between the combustion gas and the combustion gas of the combustor If it is a structure which has a main body, it is satisfied.

The coiled cooling tube 10 inside the combustor 6 has a length such that the cooling water can be sufficiently converted to a high pressure saturated steam during the passage of the combustor 6, and the discharge pipe is the suction pipe 16 of the engine body 12. ), The exhaust pipe 18 of the engine body 12 is connected to the condenser 40, the condenser 40 is the inlet of the cooling chamber of the cylinder 20 of the engine body 12 and the low pressure water supply pump (42) ), The outlet of the cooling water is connected to the heat exchanger 44 installed in the exhaust pipe of the engine body (8) and the heat exchanger (44) and the inlet pipe of the cooling pipe (10) through the high pressure water pump (46) Configure the connection.

The present invention is the combustion gas generated by the combustion when the ignition of the combustor 6 is cooled to an appropriate temperature by heat exchange with the coil-shaped cooling tube 10 passing through the combustion chamber inside, the cooled combustion gas is the engine body through the exhaust pipe (8) is introduced into the Brayton cycle (Brayton Cycle), the saturated steam converted into heat exchange with the combustion gas during the passage of the cooling tube 10 is introduced into the engine main body 12 through the exhaust pipe and the Rankine cycle ( Rankin cycle) to gain momentum.

However, in the initial ignition, since the cooling pipe 10 passing through the combustor cannot sufficiently exchange heat with the combustion gas, the engine main body 12 operated by steam cannot expect normal operation, but this is a high pressure water supply pump 46. If a heating means such as a heating wire is provided in the tube between the cooling tube and 10, the solution can be easily solved.

In addition, due to forced convection by the impeller 14 facing the injection nozzle during combustion, the combustion gas undergoes heat exchange with the cooling tube 10 more quickly, thereby reducing the capacity of the combustor and the length of the cooling tube 10. I can do it.

On the other hand, in the engine body 8, the combustion gas or vapor is introduced into the compression chamber partitioned with the exhaust chamber by the partition plate 30 through the inlet pipe 16, and the compression chamber gradually increases in volume and is installed eccentrically on the propulsion shaft. The rotation of the piston 24 results in propulsion.

At this time, the inlet pipe 16 of the engine main body 8 and 12 is opened by the opening and closing plate 32 at the moment when the sealed surface having the longest section from the center of the propulsion shaft 22 passes through the inlet pipe 16 and the combustion gas or the like. The expansion is made by the inflow of steam, the amount of inflow is to allow the exhaust gas to maintain the same pressure as the atmospheric pressure when possible, and when the appropriate pressure is supplied, the opening and closing plate 32 blocks the inlet pipe 16 Make sure the exhaust gas is always at atmospheric pressure.

In addition, the piston 24 of the engine body 8, 12 is composed of a main body 34 fixed to the propulsion shaft 22 and a sealing ring 38 between the main body 34 and the bearing 36, The sealing ring 38 can partition the compression chamber and the exhaust chamber by simple contact with the inner wall of the cylinder 20, thereby minimizing wear.

In the present invention, the combustion gas of the high temperature during combustion is cooled to an appropriate temperature by the cooling tube 10 passing through the inside of the combustor 6, so that it can be expected to completely burn, thereby minimizing the generation of harmful gases.

In particular, the engine is compressed by the Brayton Cycle, which allows the engine to be compressed by the inflow of combustion gas generated during combustion of the combustor, and by the inflow of saturated steam, which is converted during the heat exchange for cooling the combustion gas. It is possible to operate two engines with one combustor 6 by constructing a combined cycle of a cycle (Rankin Cycle).

As described above, the present invention can expect complete combustion by allowing the combustion gas to be cooled to an appropriate temperature by the coil type cooling tube 10 passing through the combustor 6, thereby minimizing the emission of harmful gases, and using combustion gas. It is a useful invention that can maximize the thermal efficiency as well as double the propulsion force at a low fuel cost by obtaining power through a combined cycle of Rankine cycle using the converted steam during heat exchange of the Brayton cycle and combustion gas.
