Claims

[Scope of utility model registration request]

A heat exchange section 4 in which a plurality of heat exchange elements 3 are arranged at the intersection of the exhaust duct 1 and the heat supply duct 2, both of which have a sealed structure.
is arranged, the high-temperature waste fluid flows outside the heat exchange element 3 from the exhaust inlet 5 at the bottom of the heat exchange section 4 toward the exhaust outlet 6 at the top, and the low-temperature feed fluid flows through the heat exchange section 4. A cleaning pipe that injects cleaning liquid into a discharge outlet 6 in a device that recovers waste heat by circulating inside a heat exchange element 3 from a heat supply input lower on the upper side toward a temperature supply outlet 8 on the lower side. 1
1, a cleaning liquid supply device 14 which selectively supplies warm water and the cleaning liquid under pressure to the cleaning pipe 11 via a stop valve 12; and a cleaning liquid supply device 14 disposed in front of the heating input lower, heating port 8 and exhaust inlet 5, duct closing valves 15, 16 and 17 for sealing the exhaust duct 1 and the heating duct 2, respectively;
From a pipe 19 that connects the cleaning pipe 11 and the temperature supply inlet side duct of the duct shutoff valve 16 via the stop valve 18, and from the drain port 10 that forms the tip of the cleaning waste liquid receiving tray 9 provided below the drain inlet 5. A drain pipe 21 connected via a stop valve 20, a pipe 23 connecting this drain pipe 21 and the temperature supply inlet side duct of the duct shutoff valve 16 via a stop valve 22, and a pipe 23 connected to the temperature supply inlet side duct of the duct shutoff valve 16 near the lower temperature supply inlet. A cleaning device for an exhaust heat recovery device, characterized in that it is equipped with a drainage port 24 provided on the top surface of a hot duct 2.
