る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat recovery system for heated waste water that recovers waste heat of heated waste water containing harmful substances through a heat exchanger.
従来、例えば染色機などからは多量の温排水が発生する
が、この多量の排熱を回収するシステムの開発が望まれ
ていた。Conventionally, dyeing machines and the like generate a large amount of heated waste water, and there has been a desire to develop a system that can recover this large amount of waste heat.
この発明は、温排水の排熱を熱交換器を介して回収する

装置を設けたことを特徴とするものである。This invention aims to prevent harmful substances from flowing into the secondary side (heat recovery line) of the heat exchanger when the heat exchanger is damaged, when waste heat of heated wastewater is recovered through the heat exchanger. A heat exchanger is installed to exchange heat between the drainage line from the hot water tank and the circulation line of the hot well tank.A primary side pressure cage is installed in the drainage line, and a circulation pump and secondary side pressure are installed in the circulation line. The pump is characterized in that it is provided with a control device which is provided with a cutout and an orifice, and which controls the circulation pump by signals from the downstream pressure cutout and the outlet pressure cutout and the secondary side pressure cutout.

This is the drainage line from. The drainage line 3 is provided with a pump 4 and a primary side pressure filter 5. 6 is a hot well tank 11 which is a circulation line of the hot well tank 6. The circulation line 7 is provided with a circulation pump 8, a secondary pressure inlet 9, and an orifice 10. In the figure, 11 is a make-up water inlet pipe, and 12 is a drain pulp. 13 is a heat exchanger for exchanging heat between the drainage line 3 and the circulation line 7. 14 is a control device that controls the circulation pump 8 based on signals from the primary side pressure switch 5 and the secondary side pressure switch 9. In the figure, 15 is an alarm.

けばよい。In the above configuration, the operation will be explained. Since the orifice 10 pressurizes, the secondary side pressure switch 9 is normally larger than the primary side pressure switch 5. In this case, normal operation is being performed. In the event of an abnormality, harmful substances may flow into the secondary side if - the downstream pressure is greater than the secondary side pressure. In that case, the control device 1

Issue an alarm. If an alarm occurs, drain the drain using the drain valve 12.
以上のようにこの発明によれば、有害物が二次側の熱回
収ラインに混入するのを防止することができる。As described above, according to the present invention, it is possible to prevent harmful substances from entering the heat recovery line on the secondary side.
