Detailed Description
The technical scheme of the utility model is specifically explained by combining an embodiment and the accompanying drawings, and as shown in figures 1-2, the utility model discloses a heat exchanger waste heat recycling device which comprises a hollow heat insulation baffle layer 1 arranged at an outlet section 21 of a heat exchanger and a water tank 4 communicated with the heat insulation baffle layer 1, wherein the installation height of the water tank 4 is higher than that of the heat exchanger. In order to better preserve heat and prevent heat from being emitted, a sealing interlayer is arranged in the heat insulation baffle layer 1.
The bottom of the water tank 4 is provided with a heat exchange water inlet and a heat exchange water outlet, and the two water inlets are respectively connected with the heat insulation baffle layer 1 through corresponding pipelines. Specifically, the heat exchange water outlet end 5 of the pipeline is communicated with the water inlet 2 of the heat insulation baffle layer 1. The water inlet 2 is arranged at the lower part of the heat insulation baffle layer 1, and the water outlet 3 is arranged at the upper part of the heat insulation baffle layer 1.
And the pipeline heat exchange water inlet end 6 of the water tank is communicated with the water outlet 3 of the heat insulation baffle layer 1. The height of the pipe heat exchange water outlet end 5 is lower than that of the pipe heat exchange water inlet end 6.
An overflow port 9 is arranged at the upper end of the water tank 4, and a hot water outlet 7 is arranged at the lower part of the water tank 4. And a water replenishing port is arranged on the water tank 4, and a floating ball type water replenishing valve 8 is arranged on the water replenishing port and used for automatically replenishing water.
An anti-scald baffle 11 is further arranged on the outer side of the heat insulation baffle layer 1, and a gap is formed between the anti-scald baffle 11 and the heat insulation baffle layer 1.

The following brief description of the principles of the utility model:
the high temperature tail gas of 900 ℃ at the radiant tube 22 enters the heat exchanger through the position A, and is discharged through the outlet end B end of the heat exchanger after being cooled to about 400 ℃ after passing through the heat exchanger. At the moment, the temperature of the pipeline surface of the outlet section 21 of the heat exchanger is still high, cold water in the water tank 4 enters the lower part of the heat insulation baffle layer 1 through the pipeline heat exchange water outlet end 5, the water temperature in the heat insulation baffle layer 1 rises after high temperature, the volume expands, and hot water enters the water tank 4 from the water outlet 3, so that the heat exchange between the water in the water tank 4 and the water in the heat insulation baffle layer 1 is realized, and the purpose of collecting waste heat is better achieved.
The hot water in the water tank 4 can be used for flushing salt on the ground in a workshop, so that a new heating device is prevented from being added for heating water, the original heat emission is reduced, and the cost is saved.
