Abstract

PURPOSE:To prevent the entry of harmful substances into the secondary side of a heat exchanger at the time of breakage of the heat exchanger by a method wherein a circulation pump is controlled by a signal from a pressure switch on the primary side of an exhaust water line and a signal from a pressure switch on the secondary side of a circulation line. CONSTITUTION:In case where the heat exchanger goes out of order, thre is a danger of the harmful substances entering the secndary side of the heat exchanger when the pressure of the primary side is higher than that of the secondary side. Therefore, when the above condition is judged to exist by a discriminator of a control device 14, only the circulation pump 8 is stopped and an alarm signal is generated whereupon the water in the heat exchanger is drained through a drain valve 12.

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.

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
