Description

Vertical Horizontal Hybrid Heat exchanger Module type heat exchanger

The present invention relates to a vertical horizontal hybrid heat exchanger module and a modular heat exchanger.

In general, a heat exchanger refers to a device that transfers heat from a fluid with a high temperature to a fluid with a low temperature through a heat transfer wall. The fluid used in the heat transfer tube may be classified into a liquid fluid such as cooling water or a refrigerant flowing in the heat transfer tube, a liquid fluid such as cooling water flowing through the outer surface of the heat transfer tube, a solid fluid such as a catalyst, and a gaseous fluid such as air.

And the classification according to the heat transfer method of the heat exchanger is a multi-tube type heat exchanger in which fluids of different temperatures flow in a space separated by a heat transfer wall and heat is transferred by heat conduction through the heat transfer wall and fluid convection on the surface of the heat transfer wall. Heat exchangers, double tube heat exchangers and surface heat exchangers of various structures, contact a solid heat storage agent (a medium that stores heat) with a high temperature fluid to absorb heat from the high temperature fluid, and then contact the low temperature fluid As a heat exchanger that transfers heat to a low temperature fluid by -type exchanger),

There is a direct-contact heat exchanger that heats two fluids by directly contacting them.

In addition, the classification of the use of the heat exchanger is an evaporative cooling tower, an air cooled cooler, a refrigerant condenser, a heater, an evaporator, a preheater, etc. there is.

And, the structure of the heat transfer tube of the tube includes a serpentine-type heat transfer tube configured by continuously bending a curved tube portion (“U” shape) and a straight tube portion between the fluid inlet header and the fluid outlet header, and the fluid inlet A serpentine-type heat transfer tube is formed by welding a curved tube (U-bend) to the end of a straight tube portion and a straight tube portion between the header and the fluid outlet header, and a straight tube is formed between the fluid inlet header and the fluid outlet header. type heat pipe, etc.

In addition, a heat exchanger in which a liquid fluid such as cooling water flows to the outside of the heat transfer tube and exchanges heat generally constitutes a bare tube heat transfer tube. It is common to configure a heat transfer fin.

In addition, the heat pipe is generally composed of a copper tube, but may also be composed of a stainless tube or a hot-dip galvanized steel tube.

In addition, it may be classified into a vertical type heat exchanger and a horizontal type heat exchanger according to the arrangement shape of the heat transfer tube.

1 is a perspective view of a conventional vertical heat exchanger (1). As shown in FIG. 1 , the heat source in which gas and solid are mixed is introduced from the lower side of the housing and discharged to the upper side, and the heat source is transferred to the fluid inside the heat pipe, and the fluid is passed through the fluid inlet 3 at the lower left. It can be seen that the heat transfer tube is supplied to the inside of the heat transfer tube and is composed of a vertical tube 6 arranged vertically and a U-bend 5 bent to connect the lower portion and the upper portion of the vertical tube 6 . And the support 7 for supporting the heat pipe as a whole is installed at regular intervals.

Such a vertical heat exchanger has disadvantages such as high flow rate, wear, difficulty in fixing the heat exchanger in the reactor, and the need to install supports for fixing the heat exchanger at regular intervals. In addition, abrasion of the support and connection pipe and smooth movement of particles may be disturbed (settling starting point), and since the high-temperature coolant (fluid) heat-exchanged from the top flows to the bottom, the heat transfer effect is reduced, and the flow of coolant flows in the downward direction. It exists (bubbles, cooling water cannot be completely drained out when the operation is stopped), and there are disadvantages in that maintenance is difficult, the temperature gradient in the section is severe, so drift can occur, and the pressure load of the fluid is high, so energy consumption is high.

On the other hand, in the case of the horizontal type heat exchanger, heat transfer is better than that of the vertical type, maintenance is possible for each heat pipe, and there is an advantage that there is no pinhole generation due to welding inside, but the pressure drop of the fluid is high and abrasion due to solid particles is high. It is higher than the vertical type, and there is a possibility that particles may accumulate on the upper part of the heat transfer tube, and it is difficult to manufacture because it has to be installed with an incline to keep the gas flow rate (Ug) constant for each height.

Also, a modular heat exchanger installed by connecting a plurality of heat exchange modules is currently used.

2 is a perspective view of a conventional vertical modular heat exchanger (2). As shown in FIG. 2 , each of the vertical heat exchange modules has a fluid inlet header 110 at the bottom and a fluid outlet header 120 at the top, and a plurality of between the fluid inlet header 110 and the fluid outlet header 120 . The vertical heat pipe 8 of 120), it can be seen that it is configured to be merged and discharged.

In the case of such a modular type, 5 to 10 modules can be manufactured and installed, but the flow rate of the fluid in the heat transfer tube is small, and the flow rate of the fluid is high in the horizontal section (fluid inlet header, fluid outlet header) in the upper and lower parts, so the pressure There are disadvantages in that the drop is high, a bar is required to maintain a gap between the module and the module, and welding is required in the inner T part.

Therefore, the development of a vertical and horizontal hybrid modular heat exchanger capable of maximizing the advantages of a vertical type and minimizing the problems of a horizontal type while being modular was required.
