The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
The present utility model will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, a novel flue gas waste heat recovery device comprises an underframe 1, a bag-type dust collector 2, a heat recovery water tank 3, a fan 4, a return pipe 5, a plate heat exchanger 6, a return pipe 7, a water inlet pipe 8, a water pump 9, a water injection pipe 10, a valve 11, a water outlet 12 and other components.
The upper end of the underframe 1 is fixedly provided with a cloth bag dust collector 2 and a heat recovery water tank 3, and an air outlet of the cloth bag dust collector 2 is connected with a fan 4. The air outlet connection of fan 4 is equipped with return pipe 5 to return pipe 5 is fixed to be located inside the heat recovery water tank 3. A plate heat exchanger 6 is arranged inside the bag-type dust collector 2, and the plate heat exchanger 6 is communicated with the heat recovery water tank 3. Meanwhile, a water return pipe 7 and a water inlet pipe 8 are connected between the plate heat exchanger 6 and the heat recovery water tank 3, and a water pump 9 is connected on the water return pipe 7. The upper end of the heat recovery water tank 3 is communicated with a water injection pipe 10, and a valve 11 is arranged on the water injection pipe 10. The side bottom of the heat recovery water tank 3 is provided with a drain outlet 12.
In the use process, high-temperature flue gas discharged by the combustion equipment enters the return pipe 5 through the bag-type dust collector 2, and further, the flue gas waste heat recovery is realized in the heat recovery water tank 3. The return pipe 5 can be used to adjust the flow of flue gas if necessary to ensure that the flue gas passes through the return pipe 5 at a suitable rate. The water pump 9 pumps water into the plate heat exchanger 6 to exchange heat with heat energy in the bag-type dust collector, and when the bag-type dust collector is used for dust collection, heat lost by flue gas is recovered, so that the waste heat recovery efficiency is further improved. If the water level in the heat recovery water tank 3 drops, water can be injected into the heat recovery water tank 3 through the water injection pipe 10 to maintain a proper water level. Meanwhile, the valve 11 may be used to control the flow rate and time of the water injection to increase the accuracy and control of the water injection.
In actual use, dust and particles in the flue gas enter the bag-type dust collector 2, and the dust and the particles are left through the filtering effect of the filter bag, so that the purpose of flue gas dust removal is achieved. The flue gas after dust removal treatment flows into the heat recovery water tank 3 for waste heat recovery.
