不経済である。In such heat recovery equipment, insoluble substances contained in the hot waste water adhere to the surfaces of the heat exchanger tubes and fins of the heat exchanger, resulting in a significant decrease in heat transfer performance and obstruction of the flow of the hot waste water. Not only does it cost a lot of money and effort to clean and replace the heat exchanger. Furthermore, depending on the nature of the undissolved substances, the heat exchanger may need to be made of corrosion-resistant materials;
It is uneconomical.

Publication No. 9071 describes the purpose of a heat exchanger that uses combustion gas to heat a fluid flowing through water pipes, to remove harmful components contained in the combustion gas and to improve heat exchange performance. The following invention is shown. However, in these inventions, since harmful components are present in the cleaning fluid in the cleaning fluid chamber where heat is stored in the water pipes where heat is recovered, harmful components, etc. may adhere to the surface of the water pipes.
Furthermore, due to these harmful components, the perforated plate forming the cleaning liquid chamber tends to become clogged, making cleaning and other maintenance difficult. In addition, when the flow rate of combustion gas fluctuates, the amount of heat recovery does not remain constant (one of the inventions has been made in view of the above-mentioned drawbacks, and the purpose of the invention is to prevent insoluble substances from adhering to the heat exchanger. It is an object of the present invention to provide an apparatus that has high heat transfer performance, is easy to maintain such as removing insoluble substances or cleaning a heat exchanger, and can obtain a stable amount of heat recovery.
本発明の一実施例を第２図により説明する。温水槽１内
には砂のような固形粒子からなる濾過材５が熱交換器２
を埋設する程度に充填されている。An embodiment of the present invention will be described with reference to FIG. In the hot water tank 1, a filter material 5 made of solid particles such as sand is installed in a heat exchanger 2.
It is filled to the extent that it is buried.
この濾過材５が温水槽１から流出するのを防ぐために、
排温水流出口４にはフィルタ６が設けられている。また
、不溶解物を含む排温水は、温水槽１内の濾過材５上方
に設けられた排温水流入口５から温水槽１内に流入する
。In order to prevent this filter material 5 from flowing out from the hot water tank 1,
A filter 6 is provided at the exhaust hot water outlet 4. Further, the waste hot water containing insoluble matter flows into the hot water tank 1 from the waste hot water inlet 5 provided above the filter material 5 in the hot water tank 1 .
以上のような構成にすれば、排温水が濾過材５によって
濾過されて、排温水に含まれる不溶解物質は濾過材面７
上に残り、不溶解物質を含まない温水だけが濾過材５中
を通って流下し熱交換器２と接触することＫなる。With the above configuration, the waste hot water is filtered by the filter material 5, and the insoluble substances contained in the waste water are removed from the filter material surface 7.
Only the hot water remaining above and containing no undissolved substances flows down through the filter medium 5 and comes into contact with the heat exchanger 2.

とができる。As a result, insoluble substances in the waste hot water do not adhere to the surface of the heat exchanger 20. Therefore, the heat exchanger does not have the problem of deterioration of heat exchange performance due to insoluble substances adhering to it, and is easy to clean. Moreover, even if the undissolved substances are corrosive, there is no need to line the heat exchanger with corrosion-resistant material, and the flow of waste hot water flowing into the hot water tank 1 is constant. Even if it is a regular filter, since the heat capacity of the filter medium 5 is large, constant heat recovery can be performed due to the heat storage effect.

守が簡単でかつ熱回収量の一定した熱回収―置を得るこ
とができる、As explained above, according to the present invention, it is possible to obtain a heat recovery system with high transfer performance, easy maintenance, and a constant amount of heat recovery.
