Abstract

PURPOSE:To improve the performance of a heat accumulating apparatus, by passing a high- temperature gas or a low-temperature gas through gas-permeable solid elements, heating heat accumulating elements by radiant heat radiated from the gas-permeable solid elements, and making the solid elements absorb the radiant heat radiated from the heat accumulating elements. CONSTITUTION:Heat accumulating elements 3 are disposed in the form of parallel layers with proper spacings from each other, and gas-permeable solid elements 8 obtained by processing a heat-resisting material into a gas-permeable member with pores or the like are interposed between the heat accumulating elements 3. A high-termperature gas or a low-termperature gas is passed alternately through the gas-permeable solid elements 8. For instance, if the heat accumulating elements 3 are fixed to a turning shaft 2 in the form of a plurality of layers and they are heated directly by high-temperature gas introduced from an inlet port 4, the high-temperature gas is passed also through the solid elements 8, so that the heat accumulating elements 3 are heated by the radiant heat radiated from the solid elements 8. When the section of the heat accumulating elements 3 heated to a high temperature is turned to the right half region of the apparatus where low-temperature gas is passed, the low-temperature gas is heated directly by convection, and at the same time, heat radiated from the elements 3 is absorbed by the solid elements 8 located on the right half section. Further, the low-temperature gas is heated when it is passed through the solid elements 8.

Description

[Detailed Description of the Invention] This invention utilizes the thermal energy of the combustion exhaust gas and other high-temperature gases emitted from the combustion furnace. I
Regarding stone heat storage*W, which is stored and used effectively.

A heat storage device that saves energy by retaining and storing the heat of high-temperature gas in large thermal materials such as bricks, and then extracting the heat one after another and using it effectively when necessary. Since the heat was transferred to the heat storage body almost exclusively by K in the new method, the heat transfer efficiency was poor, and therefore, if the surface area was large ≦ bare, the heat would not be transferred effectively, which was a big surprise. I was also unable to get a good response from the engineer.

This invention aims to eliminate the above-mentioned drawbacks of heat storage devices, and is made by using a heat-resistant material in a porous manner.
11 ** Formed in a corner shape, with a breathable integrated structure,
lI-gar winter allows Ii-gas to flow through, heats the 5 heat storage body with the radiant heat emitted from the test air, or IF
The radiant heat radiated from one piece is absorbed by the scissors and the two pieces. A jump in power transmission efficiency! We are trying to improve the

First of all, let me explain whether it's a connoisseur or a temperament disorder. This is all midwinter, 1. Yo-ho...? It:! I! l? --Shi is subdued, 11 eka, 4 trivial,..., delicacy, etc., g! sex badge,

The radiation ability of 1/a is much higher than that of air (compared to 1*), so if you apply the heat of high-temperature gas to this permeability once, a large amount of radiation will be 1! Therefore, the first factor of the radiation shape l! of radiant heat will be explained.
If high-temperature gas such as combustion exhaust gas is flowed to the right in the same figure, the high-temperature gas will become as low as an electric lamp as shown by curve a due to convection and radiant heat transfer. In each layer 111, 11..., the radiant heat emitted to the inflow side ω and outflow side of the °r*ai gas flow in the town is indicated by the arrow Fs,
Fh〜-ru, but among them, radiant heat #@, 1g, shi6
．． Since F5 is attenuated within the hyperatmospheric sphere, it can be said that the radiant heat is ultimately radiated mainly toward the inflow side (G).

Figures 1 to 4 show the heat storage device according to the present invention.
This example shows a rotating shaft at the center of the cylindrical vessel 1! is supported, and disk-shaped heat storage bodies 3, 3... are supported on the rotating shaft.
・ are fixed in a laminated manner to cover the gap, 4 is an inlet for high temperature gas, 5 is an outlet thereof, 6 is an inlet for low temperature gas,
7 is its outlet. @, I...□ is each heat storage body 8
．． The air permeable solid is interposed in the gap between the parts 3 and 3, and each air permeable solid is attached with its outer peripheral edge fixed to the inner wall surface of the unit 1. And the left half through which high-temperature gas passes and the right half through which low-temperature gas passes are partition I! It is divided by 9. The rotary shaft is rotated at low speed in the normal state,
Alternatively, by rotating ito@electrically intermittently during the running time 11, the heat storage bodies 3, 3, etc. can be switched between the left and right sides in a timely manner.

In that case, the high temperature gas flowing in from the inlet 4 is transferred to the heat storage body 1.3.
... to directly heat the heat storage bodies m, s... (i.e., convection heat transfer), and at the same time, the breathable solid 8.8
By flowing through the air-permeable solid S, radiant heat is emitted from the air-permeable solid S to heat the experimental heat storage bodies 3.3.

When the heated heat storage weight, l..., moves to the right half of the low temperature gas, it directly heats the low temperature gas by the convection of the low temperature gas, and at the same time, the heat storage body 3. The radiant heat radiated from the field is absorbed by the breathable solid field on the right half, and furthermore, the image area gas flows through the wrinkled structure to heat the low-temperature gas. Therefore, the gas heated thereby can be effectively used for the primary air of the Illll shaft, the burner, or for preheating the object to be heated.

As shown in FIG. 1, the radiant heat of the breathable solid body is radiated to the gas inlet side at a high level. S' is provided so that radiant heat is radiated to the storage unit within it.

Although this example has been explained by using the storage unit, the same heat exchange effect can be obtained even if the high temperature gas ice flow path and the aim gas flow path are switched. Of course, it is not the case that high-temperature gas and low-temperature gas are always separated by E1m. The second flag is being carried out in the distance.

In short, in the heat storage device of the present invention, since the gastric side of the heat storage body is made of a breathable solid material, the heat transfer efficiency between the heat storage body and the high-temperature gas or insect gas is very good. It is a useful device that greatly improves the performance of the device and greatly contributes to the labor saving and energy saving of various thermal equipment.
