Embodiment 1

[0065] The segmented flue gas purification treatment and waste heat recovery system device of the present invention such as figure 1 As shown: the system device includes a recovery tower 1, the air outlet at the lower end of the recovery tower 1 is connected to the air inlet at the top of the recovery water tank 6; A water film device 3; the lower part of the recovery water tank 6 is connected to the heat exchanger 4 through the first water pump 5, and the heat exchanger 4 is connected to the first liquid atomizing nozzle 2 of the recovery tower 1 and the first water film device 3 through a pipeline; The water tank 6 air outlets are connected in series with the 9 air inlets of the multi-stage spray gas cabinets, the 9 air outlets of the spray gas cabinets are connected with the multi-stage photolysis gas cabinets 12 air inlets in series, and the air outlets of the photolysis gas cabinets 12 are connected with The air inlet of the induced draft fan 14 is connected, and the air ...

Embodiment 2

[0072] Different from Embodiment 1, the spray gas cabinet 9 is directly connected to the discharge tower 17 through the induced draft fan 14, and the system does not have a photolysis gas cabinet 12. Only step 1, step 2 and step 4 of the first embodiment are implemented, and step 3 is not involved.

Embodiment 3

[0074] The difference from Embodiment 1 is that the recovery water tank 6 is directly connected to the photolysis gas cabinet 12, and the system does not have a spray gas cabinet 9. Only step 1, step 3, and step 4 of Embodiment 1 are implemented, and step 2 is not involved.

Abstract

The invention provides a sectional-type flue gas purifying treatment and waste heat recovery system device and a using method of the system device. A recovering tower, a spraying gas tank, a photolysis gas tank and a discharging tower in the system device are flexibly combined according to the components of the flue gas to be treated, different medicals are allocated or photolysis and oxidization techniques are adopted to treat so as to completely clean the flue gas with complex components, purify dust particles and toxic and harmful gas such as sulfur dioxide and hydrogen sulfide, and synchronously recover waste heat of flue gas and steam, in this way, the environment protection object of flue gas clean emission is reached. The sectional-type flue gas purifying treatment and waste heat recovery system device has the following beneficial effects that the flue gas is subjected to dust particle cleaning and waste heat recovering and then is subjected to multiple chemicals sectional reaction and absorption, and multi-stage photolysis and oxidizations so as to treat the toxic and harmful gas in the flue gas, finally the qualified gas is exhausted in air. The system device is suitable for the flue gas generated in industrial incinerations and industrial drying treatments, and is further suitable for the flue gas generated in incinerations of garbage and other substances.

Description

technical field [0001] The invention relates to the treatment of flue gas produced during industrial incineration and drying treatment and a waste heat recovery system device, in particular to a segmented flue gas purification treatment and waste heat recovery system device and its use method. Background technique [0002] At present, the control of flue gas emission is becoming more and more strict at home and abroad. Especially the flue gas produced during industrial furnace incineration, garbage incineration, sludge drying and incineration contains not only dust particles and water vapor, but also sulfur dioxide, nitrogen oxides, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide Various toxic and harmful gases such as sulfide, ammonia, and styrene must undergo strict purification before they can be discharged into the atmosphere. The national standard GB16297-1996 "Comprehensive Emission Standard of Air Pollutants" and GB14554-93 "Emission Standard o...
