Abstract

According to the present invention, a heat exchanger jacket in which a spiral heat exchanger plate is formed in a double layer is laminated in a multi-layered manner by a diaphragm having a hole in a distribution hole, so that high-temperature waste liquids are circulated downward from the top to the bottom along each heat exchanger jacket. The fresh liquid at low temperature is to be circulated upward from the lower side to the upper side along each heat exchange jacket, but heat exchange is performed when these high-temperature waste liquid and the low temperature fresh liquid are circularly circulated through the double-helix heat exchanger. As for the heat exchanger to be built,

Since the heat exchange plate 13 is installed inside the heat exchange jacket 10 in a double spiral form, it is possible to secure a large heat exchange area, and since the heat exchange jacket 10 configured as above is laminated in multiple layers without idle space, the heat exchange area is wide. The efficiency can be maximized, and the fluid movement space is large, allowing not only heat exchange while also distributing fluid containing a large amount of foreign substances, but also high temperature and high pressure.

When the heat exchange jacket 10 is stacked, the external idle space is excluded from the source, thereby providing a heat exchanger having relatively high heat exchange efficiency while reducing volume and volume.

Description

Heat exchanger

The present invention relates to a heat exchanger for preheating freshly supplied fresh liquid material using high temperature heat of waste liquid material from high temperature waste liquid material generated when operating various plant facilities or sanitary facilities. .

In more detail,

The heat exchanger jacket in which the spiral heat exchanger plate is formed inside the outer casing is laminated in multiple layers by the diaphragm which is perforated with a distribution hole, so that the high-temperature waste liquid is circulated downward from the upper side to the lower side along each heat exchanger jacket, The liquid is to be circulated upward from the bottom to the top along each heat exchange jacket, but the heat exchange is performed when these high-temperature waste liquid and low-temperature fresh liquid are circularly circulated through the double-helix heat exchanger. Relates to a device.

The present invention forms a heat exchanger plate provided inside the heat exchanger jacket separated by the diaphragm plate in a double spiral type, which maximizes the heat exchange area and secures a large circulation path so that there are many foreign substances. It can be used under high pressure and high temperature while allowing the power to circulate, but it can be used for various waste waters, such as dyeing waste water, abrasive waste water, paper waste water, washing waste water, bathroom / pool waste water, and liquid materials such as palm oil and cooking oil with high viscosity. It is possible to perform heat exchange while circulating as well,

In particular, to maximize the utilization of the installation space to reduce the size of the volume (COMPACT) while providing a relatively large capacity to provide such a heat exchange device that can greatly improve the heat exchange efficiency.

Conventionally, heat exchangers using wastewater heat have been widely known.

In the conventional heat exchanger, a distribution pipe is installed in the form of a spring coil in a sealed container in which supply and discharge ports are spaced up, down, or left and right, or a plurality of linear distribution pipes are installed to penetrate opposite surfaces. It is mainly known to connect separate supply and discharge pipes at both ends of the distribution pipe. The distribution pipe mounted inside the sealed container circulates the wastewater of the device and the low temperature purified water in the closed container to allow heat exchange. It is supposed to be done.

The conventional heat exchanger constructed and operated as described above has a small heat exchange area, which reduces heat exchange efficiency. If the flow pipe is installed too much to increase the heat exchange efficiency, the diameter of the flow pipe is narrowed, and the circulation rate decreases, and various foreign matters are smooth. There is a problem that the efficiency of the efficiency of the water is reduced by preventing the flow of water purification (passage) passing through the inside of the hermetically sealed container if the installation of a lot of distribution pipes to be in contact with the inner surface is not discharged.

As a known heat exchanger, a wastewater heat recovery system disclosed in Korean Utility Model Publication No. 81-477 is mentioned. A plurality of heat pipes are piped in the longitudinal direction to the inside of the heat exchanger cylinder which is cylindrical and both sides are closed, but both ends of each heat exchanger tube are exposed to the side of the heat exchanger tube. In this way, a plurality of heat exchanger pipes in which heat pipes are piped inside are installed to be inclined alternately, and the heat exchanger pipes of adjacent heat exchanger pipes are connected by separate connection pipes. It is provided with a discharge chamber, each heat exchange cylinder is to connect the proximal portion to the distribution pipe, but the upper end and the lower end is provided with a purified water supply port and the purified water discharge port.

If heat wastewater is supplied through the supply chamber provided at the bottom of the heat exchanger cylinder located at the lowest side, the heat wastewater is circulated and rises sequentially along the heat pipes of each heat exchanger, and is discharged through the discharge chamber, and is supplied through the upper water supply port. The low temperature purified water is sequentially circulated downwards in each heat exchanger and then discharged through the purified water outlet so as to perform heat exchange.

However, in the conventional heat exchanger configured as described above, the following problems are pointed out as disadvantages.

First, the heat exchange efficiency is low because the heat exchange area is small.

In other words, the heat transfer water is circulated through the heat pipe installed inside the heat exchange tube, so the heat transfer area varies according to the number of heat pipes installed. If the heat pipe is installed less, the heat transfer area decreases. On the other hand, even if the heat pipes are installed too much, the low temperature purified water will flow downward, so that some of the heat pipes cannot be used. There was also a distraction that hampered distribution.

In addition, since the heat exchange time was small and the heat exchange time was short depending on the contact, heat exchange was not sufficiently performed, thereby reducing the heat exchange efficiency.

In addition, the conventional heat exchanger is large in volume taking up a lot of installation space. In other words, when the heat exchanger tube with heat transfer tube inside is laminated in multiple layers, the length of the heat exchanger tube should be lengthened to widen the heat exchange area, and the heat exchanger tube is alternately inclined in order to smooth the flow of fluid. There was a problem that the volume is not generated a lot of space.

As described above, the conventional heat exchanger has a problem that the heat exchange efficiency decreases due to a large volume and a small heat exchange area.

The present invention is to provide an improved heat exchanger to solve the above problems and closed ends.

The present invention is provided with a heat exchanger jacket in which the heat exchanger plate is repeatedly wound on the inside of the cylindrical outer cylinder on the basis of the central partition plate, and both ends are hermetically fixed to the inner surface of the outer cylinder. In order to provide a heat exchanger by stacking a heat exchanger jacket in multiple layers with a diaphragm plate having a central distribution hole or an outer distribution hole formed therebetween, and alternately installing a diaphragm having a central distribution hole or an outer distribution hole interposed therebetween. There is this.

Another object of the present invention is to maintain the hot water circulation space and the cold water circulation space formed in the heat exchange jacket by the heat exchanger plate installed in a double spiral almost the same and to maximize the area of the heat exchanger plate to improve the heat exchange efficiency To provide a device.

Another object of the present invention is to secure a large circulation passage through which hot water and cold water are circulated so that heat exchange can be carried out while circulating liquid substances containing a large amount of foreign substances, and a heat exchanger device capable of being used under high pressure can be provided. It is.

The heat exchanger 1 according to the present invention is installed in a predetermined place by using a support device (means) such as a support frame 7 on the bottom.

When the heat and waste water is supplied through the hot water supply pipe 7, the heat and waste water flows into the hot water jacket 14 of the heat exchange jacket 10 located at the top, and then circulates and moves to the center side along the hot water circulation path 15. Is passed downward from the central hot water chamber (16) to pass through one of the central distribution hole 24 of the diaphragm (20) and flows into the central hot water chamber (16) of the heat exchange jacket (10) located on the lower side, the central hot water The hot water introduced into the chamber 16 moves outward along the hot water circulation path 15 and flows into the hot water jacket 14. The hot water flowing into the hot water jacket 14 of the second heat exchange jacket 10 from the upper side is introduced into the hot water jacket 14 of the third heat exchange jacket 10 through the outer distribution hole 33 in the diaphragm 30. After moving to the inside along the hot water circulation path 15, the hot water is introduced into the hot water jacket 14 of the heat exchange jacket 10 located at the lowermost side and the hot water discharge pipe 7- It is discharged through 1).

Cold water, on the other hand, is discharged by rising in countercurrent to hot water.

The cold water supplied through the cold water supply pipe 8 of the heat exchange jacket 10 located at the lowermost side is introduced into the cold water jacket 17 and circulated to the central side along the cold water circulation path 18, and the cold water is the central cold water chamber ( 19, it flows up from the central distribution hole 24 of the diaphragm 20 and passes through the central cold water chamber 19 of the heat exchange jacket 10 located second from the lower side, the central cold water chamber (19) The cold water introduced into) is circulated outward along the cold water circulation path 18 and flows into the cold water jacket 17 of the outer circumference. Cold water flowing from the lower side into the cold water jacket 17 of the second heat exchange jacket 10 is introduced into the cold water jacket 17 of the third heat exchange jacket 10 through the outer distribution hole 33 in the diaphragm 30 and then cold water. After the above process is repeatedly performed, cold water flows into the cold water jacket 17 of the heat exchange jacket 10 located at the uppermost side and the cold water discharge pipe 8-1. Is discharged through).

In this way, the hot water (heat waste water) and the cold water are circulated oppositely to each other along the hot water circulation path 15 and the cold water circulation path 18 of each heat exchange jacket 10 separated by the heat exchange plate 13 to perform heat exchange. . Therefore, the cold water supplied through the cold water supply pipe 8 is discharged while being heated to a high temperature when discharged through the cold water discharge pipe 8-1.

In the heat exchanger 1 according to the present invention, since the entire area of the heat exchanger plates 13 installed on the inside of each heat exchange jacket 10 to be stacked becomes a heat exchange area, the heat exchange area is extremely wide, thereby maximizing heat exchange efficiency. The heat exchange plate 13 installed in each heat exchange jacket 10 can utilize the internal space of the heat exchange jacket 10 without idle space, thereby ensuring the maximum heat exchange area. Heat exchange efficiency is increased because the circulation moves along the area of the circulation.

In particular, the hot water and cold water are circulated while the heat exchange is performed on both sides when the hot water is circulated along the hot water circulation path 15 and the cold water circulation path 18 so that the hot water retained can be transferred as much as possible, thereby maximizing heat exchange efficiency. Will be.

In addition, since the heat exchanger 1 according to the present invention can secure a large space ratio between the hot water circulation path 15 and the cold water circulation path 18 through which hot water and cold water are circulated, the flow can be smoothly flowed, and the viscosity is high. Fluid and mixed fluids can be circulated as well, so the type of fluids: dyed waste water, abrasive waste water, paper waste water, washing waste water, bath water and swimming pool water, pool water and high viscosity palm oil, It is possible to conduct heat exchange while circulating cooking oil.

In addition, since the heat exchange plate 13 is spirally wound, the present invention has a low pressure loss and a wide landscape (space rate of the pure environment path), so that it can be easily used to recover wastewater heat having a large amount of foreign substances, and the space rate of the circulation path is high. It can be used easily even at high temperature and high pressure fluid.

In addition, the present invention can provide a heat exchanger having a high heat exchange efficiency while minimizing the installation volume and volume because it can be installed without the idle space of the outer space when the cold water jacket 10 is laminated.

As described above, according to the present invention,

Since the heat exchange plate 13 is installed inside the heat exchange jacket 10 in a double spiral form, it is possible to secure a large heat exchange area, and since the heat exchange jacket 10 configured as above is laminated in multiple layers without idle space, the heat exchange area is wide. The efficiency can be maximized, and the fluid movement space is large, allowing not only heat exchange while also distributing fluid containing a large amount of foreign substances, but also high temperature and high pressure.

When the heat exchange jacket 10 is laminated, the external idle space is essentially excluded, thereby providing a heat exchanger having a relatively high heat exchange efficiency while reducing volume and volume.
