Abstract

PURPOSE:To permit heat exchange, excellent in thermal efficiency and capable of reducing the form of installation into one third to one half as well as averaging and controlling fluctuating heat at the same time by a method wherein supplying liquid is provided with heat at one end of a heat accumulater consisting of a heat pipe, whose other end is heated by waste gas while whose intermediate part is filled with heat accumulating liquid. CONSTITUTION:The left side of the heat accumulator 4 is the heating side heated by the waste gas 10 while the rightside thereof is a heat dissipating side. Heat, obtained from the heating sides of the heat pipes 1, 2, is transmitted once to the heat accumulating liquid 5 filling the heat accumulator 4 while sudden heat, coming from the heating side, is received and averaged by the heat accumulating liquid 5 and, thereafter, is transmitted to the heat dissipating side. The rotating speed of a rotary casing 7 is controlled by a motor 17 while the transfer degree of the heat is regulated by the mixing of the waste gas 10 due to the rotation of the heat pipes 1, 2, the mixing of the heat accumulating liquid 5 in the heat accumulator 4, mixing of the supplying liquid 11 in the heat pipes 1, 3 at supplying liquid paths 7b, 7a in the casing 7 and the control of condensation and evaporation in the heat pipe 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchange device that converts feed liquid into steam by converting heat from high-temperature waste gas into steam, and extracts energy for power generation, even if it is only 1".

Conventionally, this type of device is the so-called direct p7, in which high-temperature L^ gas is applied to a feed liquid flowing through a pipe and extracted as steam.
There is a father exchanger in Japan, but due to its inferior thermal efficiency, the size is approximately
It will increase 2 to 3 times. Unfortunately, due to corrosion and dust build-up during waste heat recovery, thermal efficiency decreased significantly over time and heat control was impossible.

Here, the present invention is a rotary heat exchanger N in which all heat pipes are applied, one end of which is heated by waste gas, and the other end of which heats the supplied liquid through a heat storage device filled with a heat storage liquid in the middle. 1 is an axial cross-sectional side view of one embodiment of the present invention.

/A is a passage for waste gas 10 in fixed casing /S.

The heat par r 7''l extends from inside the fixed gauging IS to the side 7a inside the rotating casing 7, passing through the rotating partition board/J if necessary.

Several or more can be provided. The heat pipe 2 extends from inside the fixed casing IS to the inside of the heat storage device ψ, and the heat pipe 3 is provided through the rotating partition board 13 from inside the heat storage device Hironai to the side 7a inside the rotating casing 7.

With the heat storage device 4/ as a boundary, one left side is the heating side by the gas IO, and the other right side is the heat radiation side.
The heat obtained from the heating side of the heat pipes t and l is once transferred to the heat storage liquid (oil @) J' sealed in the heat storage device Hiroshi, and the sudden tjj', H heat coming from the heating side is received by this heat storage liquid J. It is then averaged and transmitted to the cooling side. The entire heat pipe section may be separated as shown in section 3.

In this way, from the heating side, the heat pipes 1 and 2'f6 that first come into contact with the waste gas 10 at the heat storage device ψ and 2'f6 are arranged in a congruent row, and there is also another heat vibrator 3f! c Cooling from the heat storage device Hiroshi ■ Transfers heat indirectly to Ill, averages and recovers rapid heat fluctuations, transfers it to the supply liquid // of the heat waste body, which vaporizes it into steam 7.2 and generates heat. The rotating casing 7 connected to the water turbine also controls the rotational speed by the belt/

FIG.
30 is a heat pipe extending from the passage 10a'l of the waste gas 10, both ends of which are housed in the heat storage device ψ, and the intermediate portion thereof is a heat pipe through which the supply liquid // flows; J, / is the fixed casing 1. 2.2 is a separate lake that completely separates the exhaust gas population and outlet, and a hollow shaft that can be rotated by an external force (not shown).

In this embodiment as well, the heat pipes X and 30 may be used instead of the heat pipes L, and the heat from the waste gas is temporarily stored in the heat storage device V and then averaged to avoid rapid heat conduction. In addition to fully controlling the heat dissipation, absorption, conduction, and release of heat are also adjusted by controlling the rotation speed of the rotating shaft 600.

Thus, the present invention (12) has significantly better thermal efficiency compared to conventional 1σ heat exchanger means, and in its equipment configuration can be reduced to low/, while at the same time averaging and controlling fluctuating heat. This is a heat pipe heat exchanger that takes full advantage of the heat pipe's speed and maximum rotation speed.In particular, the present invention is a waste heat recovery system that requires heat control, compactness, and corrosion resistance. If applied to a system, outstanding effects will be recognized.
