Condensate and steam recovery / supply device for furnace trap type steam generation system

The present invention relates to a condensed water and steam recovery / supply device of a steam generating system for recovering and recycling high-temperature, high-pressure condensed water and steam in a steam generating system such as a closed-circuit circulation steam boiler for heating water. Condensate of the furnace trap type steam generating system that recovers and recycles high-temperature and high-pressure condensate and steam by installing a condensate collection tank at a low position without using a trap or discharging high-temperature and high-pressure steam to the outside. And a steam recovery / supply apparatus.

In general, the high-pressure steam obtained by heating the water is widely used in various fields, such as heating in the room, laundry, sewing factory, kitchen, etc., such steam is usually obtained by a steam boiler.

1 is a longitudinal sectional view showing the main part of Patent No. 613397, which is a conventional apparatus, wherein a steam supply pipe 3 is installed on an upper portion of a boiler 1 and a heat exchanger 4 is connected to an end of the steam supply pipe 3. The other end of the heat exchanger is connected to a condensate return pipe (5) for steam 22 to exchange heat in the heat exchanger and to recover condensate generated as a result of the condensate return pipe (5). It is installed.

And condensate collection tank (8) having a float switch (7) is connected to the end of the condensate collection pipe (5) and on the connecting pipe (9) connected to one side of the condensate collection tank (8) in the condensate collection tank (8) As the float switch 7 detects that the water level is above the set level, a condensate recovery pump 12 that operates by driving the motor 10 and pumps the condensate in the condensate collection tank 8 to the replenishment tank 11 is installed. The check pipe 14 is installed on the connecting pipe 9 to prevent the condensate 13 in the condensate collection tank 11 from flowing back to the condensate collection tank 8.

In addition, one side of the boiler (1) has a supplemental water tank (11) for supplying the condensate 13 recovered through the connecting pipe (9) to the inside of the boiler (1) without water head difference on one side of the boiler (1) It is installed side by side and one side of the boiler 1 is provided with an automatic water level sensor 15 for detecting the water level of the condensate 13 located inside the boiler.

The compressed air supply pipe 16 is connected to an upper portion of the supplemental water tank 11 installed at one side of the boiler 1 without having a head difference from the boiler 1, and the supplemental water tank 11 is connected to the other end of the compressed air supply pipe. Compressor 19 for generating compressed air 18 by driving in accordance with the detection that the automatic pressure control switch 17 installed in the lower than the set pressure is installed.

Further, the condensed water in the supplemental water tank 11 is supplied to another boiler (not shown) on the condensed water supply pipe 20 that supplies the condensed water 13 in the supplemental water tank 11 to the inside of the boiler 1. It is further provided with a preliminary valve 21 for branching.

Therefore, when steam (2) is generated by the operation of the boiler (1), the generated steam 22 is supplied to the heat exchanger (4) along the steam supply pipe (3) for heating and some of the steam is a separate steam It is supplied through a pipe.

In this process, when the steam is converted into the condensate 13 by heat exchange, wet steam is removed from the trap 6 in the process of being recovered to the condensate collection tank 8 through the condensate return pipe 5.

When the condensate 13 is filled in the condensate collection tank 8 and detects that the float switch 7 is above the set level, power is automatically applied to the motor 10 to operate the condensate collection pump 12 so that the condensate collection tank is operated. The condensate 13 in the inside is recovered to the make-up water tank 11 through the connecting pipe 9.

After the condensate 13 is recovered to the make-up water tank 11, the high-pressure compressed air (higher than the steam pressure in the boiler) generated by driving the compressor 19 is located in the upper part of the make-up water tank 11. Is acting through the supply pipe 16, the operation of the compressor (19) is detected by the automatic pressure control switch 17 installed on the top of the replenishment water tank 11, the pressure in the replenishment water tank (11) is boiler 1 When the pressure in the tank is higher than the steam pressure in the tank), the compressor 19 is temporarily stopped. When the pressure in the make-up tank 11 is lower than the steam pressure in the boiler 1 by the supply of condensate water, the automatic pressure control switch 17 is replenished. Since the compressor 19 is restarted until it senses that the pressure in the water tank 11 is higher than the steam pressure in the boiler 1, the pressure in the make-up water tank 11 is always higher than the steam pressure in the boiler 1. State is maintained.

In this state, when the automatic water level sensor 15 detects that the water level of the condensate water 13 in the boiler is lower than the set water level due to the continuous operation of the boiler 1, the solenoid valve 23 installed on the condensate water supply pipe 20 is Since it is open, the condensed water in the replenishment water tank 11 is replenished into the inside of the boiler 1, wherein the replenishment water is maintained even though the level of the replenishment water tank 11 is lower than the level of the boiler 1 located on one side. Since the pressure of the compressed air higher than the steam pressure in the boiler 1 is applied to the upper portion of the tank 11, the condensed water in the replenishment water tank 11 is filled in the boiler 1 through the condensed water supply pipe 20.

However, such a conventional apparatus has high pressure in the condensate pipe 5 unless the wet steam contained in the condensate is removed, so that the condensate 13 is not recovered by gravity toward the condensate collection tank 8, and thus, each condensate pipe as shown in FIG. 2. The expensive trap 24 which removes the wet steam contained in the condensed water 13 on (5) is necessarily provided.

However, even if expensive traps are installed, high-temperature, high-pressure condensate and steam or parts contained in the condensate will corrode the components that make up the trap, causing high-temperature and high-pressure condensate and steam to escape to the outside, so that expensive traps are frequently replaced. Problems of use that must be brought up.

In addition, in the trap type that does not use a trap, the high temperature and high pressure steam is discharged to the atmosphere to lower the pressure in the condensate collection tank to recover condensate generated in the heat exchanger to the condensate collection tank.

However, such a system smoothly recovers the condensate generated from the heat exchanger to the condensate collection tank side by forcibly dropping the pressure of the condensate collection tank.However, if the pressure inside the condensate collection tank drops due to a defect in the steam supply pipe or condensate piping, the pressure inside the condensate collection tank Since condensate is present as condensate in the condensate collection tank at normal pressure, when the pressure of the condensate collection tank falls below the set pressure, the condensate inside the condensate collection tank starts to evaporate and the water level decreases rapidly. In other words, the condensate is evaporated to a temperature present as water and reduced.

In this way, when the pressure in the condensate collection tank falls below the set pressure and the condensate level is reduced, pumping condensate causes cavitation damage to the pump, resulting in a fatal result of burning the motor of the pump. .

Therefore, the low water level of the condensate collection tank should be set higher than necessary so as not to cause cavitation damage to the pump, so the condensate collection tank is designed to be higher than necessary.

The present invention has been devised to solve such a problem, and the structure of the condensate generated in the heat exchanger by pumping the condensate recovered in the condensate collection tank while maintaining the same internal pressure of the entire pipe by dramatically improving the structure The purpose is to recover the high-temperature, high-pressure condensate and steam to the condensate collection tank side for recycling without removing the wet steam.

Another object of the present invention is to prevent the cavitation damage to the pump even when the condensate in the condensate collection tank to the low water level, so that the height of the condensate collection tank does not have to be designed high.

According to an aspect of the present invention for achieving the above object, the condensate collection tank is installed to recover the condensate and steam generated by heat exchange in the heat exchanger through the condensate return pipe by gravity, and is installed inside the condensate collection tank A condensate suction pipe having a plurality of through holes formed at a bottom thereof, a pump installed at an outlet side of the condensate suction pipe to pump condensate in the condensate collection tank, and installed in the condensate collection tank to control the driving of the pump according to the condensate level A water level sensing rod, a condensate pipe installed at an output end of the pump to transfer the pumped condensed water to a supplement water tank or a boiler, and a steam pipe provided to be provided with an upper portion of the condensate collection tank and provided with a first check valve; It is installed on the discharge path of the condensed water and the steam discharged to the steam vent pipe A steam tank, a second check valve installed on the condensate pipe to prevent backflow of condensate, and a steam return pipe installed through the steam tank to transfer steam to the steam recovery pipe when the pump stops driving. Condensed water of the furnace trap type steam generating system comprising a steam regeneration valve configured to be opened when the steam is compressed by the condensate by the driving of the pump and to pass the compressed steam, and to close the flow path when the condensed water rises. Steam recovery / supply is provided.

The present invention has several advantages over the conventional apparatus as follows.

First, condensate can be recovered without installing an expensive trap for each heat exchanger, thereby reducing the facility cost by about 40%.

Second, since 100% of condensed water and steam generated by heat exchange are recovered and reused, thermal efficiency is improved, thereby reducing fuel costs.

Third, cavitation damage does not occur in the pump during the condensate pumping process, thereby maximizing expensive pump life.

Fourth, it is possible to pump as much condensate recovered in the condensate collection tank as much as possible to install the water head difference with the heat exchanger as low as possible.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. It is noted that the figures are schematic and not drawn to scale. The relative dimensions and ratios of the parts in the figures have been exaggerated or reduced in size for clarity and convenience in the figures and any dimensions are merely exemplary and not limiting. And the same reference numerals are used to refer to similar features in the same structure, element or part shown in more than one figure.

3A and 3B are longitudinal cross-sectional views showing a first embodiment of the present invention, and FIGS. 6A and 6B are longitudinal cross-sectional views showing the configuration of a steam regeneration valve, and the present invention is generated by heat exchange in the heat exchanger 4. The condensate collection tank 31 is installed so that the condensate 13 and the steam 22 are recovered through the condensate return pipe 30 by gravity, and a plurality of through holes 32a are formed in the bottom of the condensate collection tank. A condensate suction pipe 32 is provided, and a pump 33 for pumping the condensate 13 in the condensate collection tank 31 is installed at the outlet side of the condensate suction pipe 32.

The reason why the plurality of through holes 32a are formed on the bottom surface of the condensate suction pipe 32 is that although the condensate 13 collected in the condensate collection tank 31 is pumped to the low water level by the driving of the pump 33, the condensate collection tank is swirled. This is to prevent the cavitation damage from occurring in the pump 33 by preventing a part of the gas (steam) in 31 from flowing into the pump 33 side.

In addition, a level sensor rod 34 is installed in the condensate collection tank 31 to control the driving of the pump 33 according to the level of the condensate 13, and the output terminal of the pump 33 is pumped condensate ( 13 is connected to the condensate pipe (35) for transferring the refill water tank (11) or the boiler (1) side and the steam pipe (37) provided with a first check valve 36 on the upper portion of the condensate collection tank (31) Is installed, and a steam tank 38 for collecting the steam 22 discharged to the steam pipe 37 is installed on the discharge path of the condensate 13.

Therefore, when the driving of the pump 33 is stopped, the first check valve 36 opens the flow path of the steam pipe 37 so that the steam 22 recovered into the condensate collection tank 31 is the steam pipe ( 37 is filled in the steam tank 38 through.

Meanwhile, a second check valve 39 is installed on the condensate pipe 35 to prevent backflow of the condensate 13, and a steam regeneration valve 40 is provided in the steam recovery pipe 40 which is installed to be in contact with the steam tank 38. 41 is provided so that the steam 22 is not transferred to the steam recovery pipe 40 when the pump 33 is stopped, and the steam 22 is driven by the condensate 13 by the pump 33. When the pressure is compressed, the pressure is opened to allow the compressed steam to pass therethrough, and the flow path is closed by the condensate 13.

The steam regeneration valve 41 is provided with a housing 42 having an inner diameter larger than the inner diameter of the steam recovery pipe 40, and a valve disc 43 having a cutting surface 43 a formed on the outer circumferential surface thereof so as to be lifted and lowered. And a coil spring 44 installed above the valve disc and having an elastic modulus greater than the pressure of steam 22 compressed by the condensate 13 and less than the pumping pressure of the condensate.

In FIG. 3A of the first embodiment of the present invention, a steam tank 38 is installed on the condensate pipe 35. In FIGS. 4A and 5A of the second and third embodiments, the steam tank 38 is a condensate collection. It is provided in the upper part of the tank 31.

Therefore, since the installation area of the second and third embodiments is reduced rather than the first embodiment, the steam generating system can be compacted.

In addition, the second and third embodiments are different from each other in the second embodiment of the steam vent pipe 37 provided with a first check valve 36 in the steam tank 38 installed above the condensate collection tank 31. ) And the steam tank 38 is directly connected to the steam tank 38 to the condensate pipe 35, but in the third embodiment, the condensate collection tank 31 and the steam tank 38 are The vent pipe 47 is provided so as to pass through, and the vent pipe 47 is configured such that the valve 48 is elastically installed by the spring 49.

Accordingly, when the driving of the pump 33 is stopped, in the second embodiment, the condensed water 13 inside the steam tank 38 is drained through the condensed water pipe 35 to the condensed water collection tank 31. In the third embodiment, the condensate collection tank 31 is quickly drained through the vent pipe 47.

In each embodiment of the present invention, it is more preferable to connect the pressure discharge pipe 52 so that the upper part of the condensate collection tank 31 and the condensate recovery pipe 30 pass through.

This causes the upper pressure of the condensate collection tank 31 to be lowered even if the condensate 13 and the steam 22 are recovered to the condensate collection tank 31, thereby reducing the condensate 13 generated by heat exchange by gravity. It is to be more quickly recovered to the condensate collection tank 31.

In addition, it is more preferable that the air discharge pipe 50 is connected so that the upper portion of the pump 33 and the condensate pipe 35 pass.

This is because the pump 33 is filled when the condensate 13 is filled in the condensate collection tank 31 even if the operator does not manually discharge the gas existing inside the pump 33 while the pump 33 is stopped. In order to prevent the cavitation damage to the pump 33 when the pump 33 is driven by allowing the gas to be discharged to the outside through the air discharge pipe 50 while the condensed water is filled to have the same head.

On the other hand, a known discharge valve 51 for discharging the cold steam to the outside on the condensate pipe 35 is further installed.

This is to recover the steam by preventing the cold steam is transported together in the process of recovering the steam 22 by the bimetal (not shown) installed in the discharge valve 51 to the steam recovery pipe 40. This is to increase the efficiency.

Referring to the operation of the present invention configured as described above is as follows.

First, in the present invention, unlike the conventional steam generation system that used the trap, as shown in Figure 7 did not use a trap.

In the steam generating system of the present invention, when the driving of the pump 33 is stopped, the condensate 13 generated by heat exchange in the heat exchanger 4 is condensate collection tank 31 through the condensate return pipe 30 by gravity. ) Will be gathered to the side.

At this time, part of the steam 22 together with the condensate 13 is introduced into the condensate collection tank 31 to be filled in the upper portion of the condensate 13, the first check valve installed on the steam pipe (37) 36 is open and the second check valve 39 installed in the condensate pipe 35 is closed so that the steam 22 introduced into the condensate collection tank 31 is steam tank 38 through the steam pipe 37. The difference is inside of.

As the condensate 13 is charged into the condensate collection tank 31, some steam 22 exits to the condensate return pipe 30 through the pressure discharge pipe 52, so that the condensate 13 flows smoothly. You lose. That is, the condensate 13 generated in the heat exchanger 4 is smoothly gathered toward the condensate collection tank 31 by gravity.

When the condensate 13 generated in the heat exchanger 4 is filled in the condensate collection tank 31 and the water level sensing rod 34 senses the high water level, the pump 33 is controlled by the control unit (not shown). Since the driving is pumped of the condensate (13).

At this time, the valve disk 43 of the steam regeneration valve 41 closes the inlet of the steam recovery pipe 40 by the coil spring 44 as shown in FIG. 6C.

When the condensate 13 in the condensate collection tank 31 is pumped by the driving of the pump 33 as described above, the condensate 13 is condensate pipe 35 through a plurality of through holes 32a formed in the bottom surface of the condensate suction pipe 32. As it is discharged into the lower portion of the steam tank 38 to be filled, the steam 22 filled in the upper portion of the steam tank 38 is compressed.

When the steam 22 filled in the upper portion of the steam tank 38 is compressed by the condensate 13 due to the continuous pumping of the condensate 13, the valve disc 43 installed in the steam recovery pipe 40 is shown in FIG. 6A. As it rises by the pressure of the steam 22 to open the flow path, the compressed steam 22 is recovered and recycled to the steam recovery pipe 40.

That is, the condensate 13 is driven into the steam tank 38 by the driving of the pump 33 to compress the steam 22 and discharge the steam 22 to the steam recovery pipe 40. In this case, the valve disc 43 closes the flow path of the steam recovery pipe 40 by the pressure of the coil spring 44 and is compressed by the condensate 13 so that the pressure is increased. The valve disk 43 acts on the bottom surface and rises while compressing the coil spring 44. However, since the elastic modulus of the coil spring 44 is only about 1/5 compressed by the pressure of the steam 22, the compressed steam 22 ) Is recovered and recycled to the steam recovery pipe 40 through the cut surface 43a formed on the outer circumferential surface of the valve disc 43.

However, when the condensate 13 rises so that the condensate 13 fills the inside of the steam tank 38 due to the continuous pumping of the pump 33, the valve disc 43 is pushed up as shown in FIG. Since the outlet of the condensate (13) is prevented from coming out of the steam recovery pipe (40).

At this time, since the first check valve 36 installed in the steam pipe 37 closes the flow path of the steam pipe 37 by the pressure of the steam 22 and the condensate 13, the steam in the condensate collection tank 31 The transfer of 22 is temporarily stopped.

As described above, after pumping the condensate 13 collected in the condensate collection tank 31 by the driving of the pump 33, the steam 22 filled in the steam tank 38 is compressed, and then sent to the steam recovery pipe 40. As shown in FIGS. 3B, 4B, and 5B, the second check valve 39 installed at the outlet of the condensate pipe 35 opens the flow path by the pumping pressure of the condensate 13, thereby transferring the condensed water to the make-up tank 11. It is possible to send directly or to the inside of the boiler 1 as needed.

In the present invention, even if the condensate 13 in the condensate collection tank 31 is pumped until just before the water level sensing rod 34 detects the low water level, cavitation damage does not occur in the pump 33.

Unlike the conventional system in which the condensate pipe 35 is directly connected to the condensate collection tank 31 and exits through the condensate pipe, the condensate suction pipe 32 having a plurality of through holes 32a formed on the bottom thereof is connected to the condensate collection tank 31. 31 is located in the interior of the condensate (13a) pumping a large amount of condensate 13 through the exit of the condensate collection tank 31 is close to the bottom of the condensate collection tank 31 so that the gas flows through the through (32a) This is because it fundamentally prevents the phenomenon.

As such, when the condensate collection tank 31 pumps the condensate 13 and the water level sensing rod 34 detects the low water level, the driving of the pump 33 is temporarily stopped, and the driving of the pump 33 is temporarily stopped. When the pressure applied to the first and

second check valves

36 and 39 and the valve disc 43 are released, the first check valve 36 opens the flow path of the steam pipe 37 and the second check valve 39 ) Is the condensate pipe 35 and the valve disc 43 to close the flow path of the steam recovery pipe 40, respectively.

Accordingly, in the first and second embodiments, the condensate 13 in the steam tank 38 is drained to the condensate collection tank 31 through the condensate pipe 35, but in the third embodiment, the condensate 13 is pumped. Since the valve 48 which closed the flow path of the vent pipe 47 while compressing the spring 49 by the pressure acted upon is opened, the flow path of the vent pipe 47 is opened by the restoring force of the spring 49 as shown in FIG. 5C. The condensed water 13 in the steam tank 38 is quickly drained to the condensate collection tank 31.

As described above, when the condensate 13 in the condensate collection tank 31 is pumped to the condensate pipe 35 by the driving of the pump 33, the steam 22 in the steam tank 38 is removed by the condensate 13. After the compression and recovery to the steam recovery pipe 40 and recycled, and then the operation of the pump 33 is temporarily stopped, the condensed water 13 and steam 22 generated in the heat exchanger 4 is condensed water recovery pipe 30 Through the condensate collection tank 31 is filled, the gas present in the pump 33 is discharged through the air discharge pipe (50) as the condensate collection tank 31 is filled with the condensate (13) continues to condensate It is possible to recover the steam as well as pumping of.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, it will be understood by those skilled in the art that the present invention may be embodied in other specific forms without changing the technical spirit or essential features. will be.

Therefore, the above-described embodiments are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention described in the above detailed description is represented by the following claims, and the meanings of the claims and All changes or modifications derived from the scope and the equivalent concept should be construed as being included in the scope of the present invention.
