Lower section is provided with multiple shower nozzles, and the sparge pipe of the shower plate is also connected by water pipe with the moist closet, and the shower plate
Water pump four is communicated with water pipe between the moist closet, watering room bottom is loaded with water, one end of the smokejack
It is connected with boiler flue gas outlet, the other end of the smokejack passes through the watering room and reaches the water surface of watering room bottom
Under,
Watering room bottom is extended with water pipe, the water pipe that watering room bottom is stretched out through first filter with
The moist closet is connected, and water pump one is also associated with the water pipe between the watering room and first filter,
The watering ceiling portion is extended with smoke pipe, and the smoke pipe that the watering ceiling portion is stretched out sequentially passes through the low-temperature heat exchange
Device and the condenser, the condenser are also connected by smoke pipe with the chimney,
The delivery port and water inlet of the cryogenic heat exchanger are connected by water pipe with the moist closet respectively, and described
Water pump two and water check valve one are also associated with water pipe between the water inlet of cryogenic heat exchanger and the moist closet.
Particularly, it is also associated with the second filter on the water pipe between first filter and the moist closet.
Particularly, the moist closet is also connected with water pump three and water check valve two by water pipe.
The beneficial effects of the utility model are：The utility model is provided with two-stage heat sink, can be by exhaust gas temperature significantly
Reduction, collects discharge the mode that water directly absorbs in flue gas by way of heat and continued through low-temperature heat exchange machine respectively
The mode of heat in low-temperature flue gas, realizes the recovery of fume afterheat, and improves waste heat recovery rate, and finally discharge
For by cooling and the gas at normal temperature condensed, moisture vapor amount is relatively low, reduces haze and produce.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, 2, a kind of low-temperature flue gas waste heat retracting device, it is characterised in that including smokejack 2, watering room 1,
Cryogenic heat exchanger 4, condenser 5, chimney 6, the first filter 8 and moist closet 7, the internal upper part of watering room 1 are provided with shower plate 3,
The shower plate 3 is interconnected by many and sparge pipe groups arranged in parallel are into every sparge pipe lower section is provided with multiple shower nozzles, institute
The sparge pipe for stating shower plate 3 is also connected by water pipe with the moist closet 7, and between the shower plate 3 and the moist closet 7
Water pipe on be communicated with water pump 4 12, the bottom of watering room 1 is loaded with water, and one end of the smokejack 2 goes out with boiler smoke
Mouthful it is connected, the other end of the smokejack 2 is through the watering room 1 and reaches under the water surface of the bottom of watering room 1,
The bottom of watering room 1 is extended with water pipe, and the water pipe that the bottom of watering room 1 is stretched out passes through first filter
8 are connected with the moist closet 7, and water pump one is also associated with the water pipe between the watering room 1 and first filter 8
