IMPOSION PUMP, AND IMPLOSION PUMP ASSEMBLY USING THE SAME}

The present invention relates to an immersion pump, and more particularly, an immersion pump capable of driving a pump by using the coagulation force of Brown gas and cooling the driving unit by using a fluid conveyed by the pump, and an immersion pump assembly using the same. It is about.

As fossil fuels are depleted and environmental pollution due to the use of fossil fuels increases, there is a growing interest in the development and practical use of energy to replace them. In this situation, one of the emerging emerging alternative energy sources is Brown Gas, a mixture of hydrogen and oxygen.

Brown gas is a 2: 1 mixture of hydrogen and oxygen, which burns with less energy input than fossil fuels and has a faster flame propagation rate. During combustion, the combustion chamber is evacuated with an implosion rather than an explosion. In addition, very small volumes of combustion products are produced and contaminants are rarely generated.

Korean Unexamined Patent Publication No. 10-2008-0007029 proposes an ignition engine using the characteristics of Brown gas. Unlike the driving principle of a conventional internal combustion engine, it is a device that generates power by operating a piston using the coagulation property generated during combustion of Brown gas.

The quenching engine is provided on a cooling flow path through which a coolant circulates outside the cylinder liner, and is installed on the outer surface of the cylinder to cool the circulating coolant, and includes a cooling device including a thermoelectric element, a radiating fin, and a radiating fan. When the epoch engine operates, the refrigerant is circulated to cool the cylinder, and the heated refrigerant can be cooled using a cooling device outside the cylinder.

However, such an ignition engine has a problem in that a separate cooling device is installed on the outside of the cylinder, and the device is complicated and bulky, and additional energy is required for the operation of the cooling device.

As shown in FIG. 1, the immersion pump of the first embodiment includes a driving unit 10 having a driving cylinder 11 and a driving piston 12, and a pump unit having a pressure cylinder 41 and a pressure piston 42. 40). The driving cylinder 11 and the pressure cylinder 41 may be arranged to coincide with their center axes, and may be integrally provided in the state in which the inside is partitioned to both sides by the partition part 30. Here, the case where the driving cylinder 11 and the pressure cylinder 41 are integrated is illustrated, but they may be combined in a state in which they are separately manufactured.

The driving piston 12 is installed in the driving cylinder 11 so as to be able to move forward and backward, and partitions the inside of the driving cylinder 11 into the first combustion chamber 13 and the second combustion chamber 14 on both sides.

The first combustion chamber 13 has a first gas inlet 15 to which the brown gas supply pipe 26 is connected so that brown gas can be introduced into the inside, and a condensate discharge pipe to discharge the condensed water generated by the combustion of the brown gas. A first condensate outlet 16 is connected.

The second gas inlet 19 and the second condensed water outlet 20 are provided with a second inlet valve 21 and a second outlet valve 22 for opening and closing the flow path, respectively. In the second combustion chamber 14, a second igniter 24 for igniting Brown gas is provided.

As shown in FIG. 2, the driving unit 10 has a coagulation when Brown gas of the first combustion chamber 13 is combusted to reduce the volume of the first combustion chamber 13, thereby driving the driving piston 12 to the pump. It may move toward the portion 40. At the same time, since the volume of the second combustion chamber 14 increases, brown gas may flow into the second combustion chamber 14. On the contrary, as shown in FIG. 3, when the brown gas of the second combustion chamber 14 is burned, the driving piston 12 may move in the opposite direction, and brown gas may flow into the first combustion chamber 13. have. As such, the driving piston 12 moves forward and backward by alternately generating the first combustion chamber and the second combustion chamber. More details regarding the operation of the driving unit 10 will be described later.

Referring to FIG. 1, the pressure feeding piston 42 is installed in the pressure feeding cylinder 41 in a retractable manner, and forms a pump chamber 43 that is variable in volume with the pressure feeding cylinder 41. The inside of the pressure cylinder 41 may be partitioned by the pressure piston 42 into the pump chamber 43 opposite the compartment 30 and the clearance 44 on the compartment 30. The free space 44 is a space for the operation of the pressure feeding piston 42, and one or more vent holes 45 communicating with the outside may be provided for smooth operation of the pressure feeding piston 42.

The pressure feeding piston 42 is connected to the driving piston 12 by one or more connecting rods 32 passing through the partition 30. Therefore, the pressure feeding piston 42 changes the volume of the pump chamber 43 while retreating by the operation of the driving piston 12.

The pump chamber 43 includes a fluid inlet 46 through which fluid is introduced into the fluid, a fluid outlet 47 through which the fluid inside is discharged, a fluid inlet valve 48 that opens and closes the fluid inlet 46, and a fluid outlet 47. It includes a fluid discharge valve 49 for opening and closing the. When the volume of the pump chamber 43 is increased by the operation of the pressure feeding piston 42, the fluid inlet 46 is opened and the fluid outlet 47 is closed, so that the fluid is sucked into the pump chamber 43. On the contrary, when the volume of the pump chamber 43 decreases, the fluid inlet 46 is closed and the fluid outlet 47 is opened, so that the fluid in the pump chamber 43 can be discharged to the fluid outlet 47. As such, the pump unit 40 moves forward and backward by the operation of the driving unit 10 to change the volume of the pump chamber 43, and the fluid inlet valve 48 and the fluid discharge valve 49 are opened and closed alternately. Pressing can be performed.

In addition, the quenching pump of the first embodiment is provided with cooling passages 52 and 54 on the outside of the driving cylinder 11 so as to cool the driving cylinder 11 by using the fluid pumped by the operation of the pump unit 40. do. This is to cool the heat generated when the brown gas is combusted in the first and second combustion chambers 13 and 14.

The cooling passages 52 and 54 are formed by the first cooling passage 52 through which the fluid flowing into the fluid inlet 46 of the pump chamber 43 flows, and the fluid flowing out of the fluid outlet 47 of the pump chamber 43. It includes two cooling passages (54). To this end, a first cooling jacket 51 having a first cooling passage 52 formed therein is installed on one outer surface (the upper outer surface of FIG. 1) of the driving cylinder 11, and the other outer surface of the driving cylinder 11 is provided. A second cooling jacket 53 having a second cooling passage 54 formed therein may be installed on the lower outer surface of FIG. 1.

In addition, the immersion pump of the first embodiment has an inlet 52a of the first cooling channel 52 so that the fluid pumped by the pump unit 40 can pass through the first cooling channel 52 and the second cooling channel 54. The first fluid inlet pipe 61 connected to the second fluid inlet pipe 62 connecting the outlet 52b of the first cooling flow path 52 and the fluid inlet port 46, the fluid outlet port 47, and the And a first fluid discharge pipe 63 connecting the inlet 54a of the second cooling path 54 and a second fluid discharge pipe 64 connected to the outlet 54b of the second cooling path 54.

As shown in FIG. 4, the first cooling jacket 51 may be provided in a semicircular cross-sectional structure so as to be mounted on the driving cylinder 11 in a form surrounding the outer surface of the driving cylinder 11. In addition, the internal space constituting the first cooling passage 52 is partitioned by a plurality of first heat transfer plates 51a so that the fluid introduced into the inlet 52a can be divided into a plurality of flow paths and flow toward the outlet 52b. The plurality of first heat transfer plates 51a extend in a direction from the inlet 52a toward the outlet 52b and are spaced apart from each other in the circumferential direction of the driving cylinder 11. Therefore, the fluid introduced into the inlet 52a may be divided into a plurality of flow paths and flow toward the outlet 52b to exchange heat with the first cooling jacket 51, thereby cooling the driving cylinder 11.

The second cooling jacket 53 illustrated in FIG. 1 may also be provided in the same form as the first cooling jacket 51 and may be mounted to surround the remaining outer surface of the driving cylinder 11. In addition, a plurality of second heat transfer plates 53a may be installed in the second cooling jacket 53.

The following describes the operation of the immersion pump according to the first embodiment.

In the state of FIG. 1, when the first igniter 23 is ignited and the brown gas introduced into the first combustion chamber 13 is burned, the brown gas of the first combustion chamber 13 is coagulated and its volume is about 1/1860. Decreases to. Therefore, since the first combustion chamber 13 is in a vacuum state, as shown in FIG. 2, the driving piston 12 moves toward the pump unit 40, so that the first combustion chamber 13 becomes small and the second combustion chamber 14 is Gets bigger In this case, the first gas inlet 15 is closed and the second gas inlet 16 is opened. In addition, the first condensate outlet 19 is opened at the time when the condensation is almost completed, and the second condensate outlet 20 is closed. Therefore, brown gas is newly introduced into the second combustion chamber 14 through the second gas inlet 19, and condensed water generated in the first combustion chamber 13 is discharged through the first condensate outlet 16.

When the second igniter 24 is ignited in the state of FIG. 2 and the coagulation occurs in the second combustion chamber 14, as shown in FIG. 3, the second combustion chamber 14 is in a vacuum state. Therefore, at this time, as opposed to the above case, the driving piston 12 moves to the opposite side of the pump unit 40 so that the second combustion chamber 14 becomes smaller and the first combustion chamber 13 becomes larger. In this case, the first gas inlet 15 is opened and the second gas inlet 19 is closed. In addition, the first condensed water outlet 16 is closed and the second condensed water outlet 20 is opened at the time when the condensation is almost completed. Therefore, the brown gas is newly introduced into the first combustion chamber 13 through the first gas inlet 15, and the condensed water generated in the second combustion chamber 14 is discharged through the second condensed water outlet 20.

The condensed water discharged through the first condensed water outlet 16 and the second condensed water outlet 20 may be collected by flowing along the condensed water discharge pipe 27 and then regenerated into brown gas through electrolysis.

As the driving unit 10 repeats the above-described operation, the driving piston 12 retreats, and the movement of the driving piston 12 moves the pressure feeding piston 42 connected by the connecting rod 32. In addition, since the volume of the pump chamber 43 is changed by the advancing and descending of the pressure feeding piston 42, the pump chamber 43 pumps the fluid in such a manner as to suck the fluid into the inside thereof and pressurize the fluid.

That is, as shown in FIG. 3, when the pressure feeding piston 42 moves toward the driving unit 10 and the pump chamber 43 becomes large, the fluid inlet 46 is opened and the fluid outlet 47 is closed. Therefore, the fluid is sucked into the pump chamber 43 at this time. On the contrary, as shown in FIG. 2, when the pumping piston 42 moves backward and the pump chamber 43 becomes small, the fluid inlet 46 is closed and the fluid outlet 47 is opened. Therefore, at this time, the fluid of the pump chamber 43 is discharged to the fluid outlet 47.

When such an operation is made, the fluid flowing into the pump chamber 43 flows through the first cooling passage 52 of the first cooling jacket 51 to cool one outer surface of the driving cylinder 11 and is discharged from the pump chamber 43. The fluid flows through the second cooling passage 54 of the second cooling jacket 53 to cool the other outer surface of the driving cylinder 11. Therefore, even if a separate cooling device is not provided as in the related art, the driving cylinder 11 can be cooled.

Since the driving piston 12 and the pressure feeding piston 42 are directly connected by the connecting rods 32 and move together, the immersion pump of the first embodiment has less energy and vibration than the pump employing a conventional mechanical engine. Efficiency is also high. Its simple structure makes it easy to manufacture and maintain.

FIG. 5 illustrates an immersion pump assembly in which a plurality of immersion pumps are connected according to a first embodiment. In other words, a plurality of immersion pumps are connected and used. Such an immersion pump assembly is branched to a fluid supply first branch connection pipe (71) connected to the first cooling passage (52) of each amp pump and branched to the second cooling passage (54) of each ump pump. The second branch connecting pipe 72 for fluid discharge, the third branch connecting pipe 73 for brown gas supply, which is branched and connected to the first and second gas inlets 15 and 19 of each amp pump, It may include a fourth branch connecting pipe (74) for condensate discharge is branched to the first and second condensed water outlet (16, 20) of the pump.

In addition, the immersion pump assembly may include a controller (not shown) for controlling the igniter of each amp pump to be ignited at a time difference. When the operation of each immersion pump with a time difference as described above, a time lag occurs in the operation of the pressure-feed piston 42 of each AMP pump can reduce the pressure fluctuation of the fluid to be conveyed.

According to the second embodiment, even when the fluid pumped by the pump unit 40 is not suitable for cooling the driving cylinder 11, the driving cylinder 11 may be cooled by using a separate cooling water. In this case, the fluid to be conveyed may not be suitable for cooling the driving cylinder 11 because the temperature of the fluid is very high or the fluid is in a gaseous state.

In addition to the configuration of the first embodiment described above, the immersion pump of the second embodiment includes a first opening / closing valve 81 provided in the first fluid inlet pipe 61 and a second opening / closing valve provided in the second fluid inlet pipe 62 ( 82), a third open / close valve 83 provided in the first fluid discharge pipe 63, and a fourth open / close valve 84 provided in the second fluid discharge pipe 64.

And a bypass inlet pipe 91 having a fifth open / close valve 85 on the way, and a fluid outlet 47 so that the fluid discharged from the fluid outlet 47 can bypass the second cooling passage 54. A second discharge valve (64) downstream of the fourth opening / closing valve (84) is connected to the bypass discharge pipe (92) having a sixth opening / closing valve (86).

Operation of the immersion pump according to the second embodiment may be performed as follows.

When the drive cylinder 11 is cooled using external cooling water, the first open / close valve 81, the second open / close valve 82, the third open / close valve 83, and the fourth open / close valve 84 are closed. The fifth open / close valve 85, the sixth open / close valve 86, the seventh open / close valve 87, the eighth open / close valve 88, the ninth open / close valve 89, and the tenth open / close valve 90 are opened. do.

In this case, the fluid is introduced into the pump chamber 43 through the bypass inlet pipe 91, and the fluid discharged from the pump chamber 43 may be discharged through the bypass discharge tube 92.
