Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
This embodiment relates to a flue gas desulfurization device installs on the flue to constitute the desulfurization treatment to flue gas in the flue, this flue gas desulfurization device carries the aqueous ammonia to the first passageway of atomizing intracavity including establishing the atomizing chamber that is linked together in flue one side and with the flue, and carries compressed air to the second passageway of atomizing intracavity. Under the action of compressed air, the ammonia water can be atomized in the atomizing cavity and discharged into the flue for flue gas desulfurization treatment, and the chemical reaction principle is 2NH3·H2o ten SO2＝(NH4)2SO3ten H2O。
Based on the above design concept, an exemplary structure of the flue gas desulfurization device of the present embodiment is shown in fig. 1, where the atomization chamber 3 is located four to five meters above the high temperature fan air outlet channel 6, and relative to the flue 1, the first channel 4 is extended from the other end of the atomization chamber 3 and extends to the flue 1 along the length direction of the atomization chamber 3, and the water spray holes 401 located on the circumference of the first channel 4 are also arranged along the length direction of the first channel 4.
Meanwhile, a plurality of support frames 7 for supporting the first channel 4 are arranged in the atomizing chamber 3, and each support frame 7 is supported on the inner peripheral wall of the atomizing chamber 3 around the circumferential direction of the first channel 4. The specific structure of the supporting frame 7 is shown in fig. 2, and it includes a mounting ring 701 sleeved on the first pipe, and a plurality of supports with one end connected to the mounting ring 701 and the other end supported on the inner peripheral wall of the atomizing chamber 3. Through setting up a plurality of support frames 7, can with first passageway 4 support mounting in atomizing chamber 3, realize the even quick blowout of aqueous ammonia to atomize under compressed air's effect. In addition, in the present embodiment, the ammonia water in the first passage 4 can flow out from the ammonia water tank, and is driven to flow by the driving pump.
In order to improve the atomization effect of the ammonia water in the atomization chamber 3, the second channel 2 is wound on the outer peripheral surface of the atomization chamber 3 along the length direction of the atomization chamber 3, and a plurality of air injection holes which extend into the atomization chamber 3 and are arranged at intervals are arranged on the second channel 2. So set up, can improve the area of contact of aqueous ammonia and compressed air, reach and show the purpose that improves the aqueous ammonia, the aqueous ammonia after the atomizing can flow in flue 1 via atomizing chamber 3, carries out abundant contact and chemical reaction with the sulphide in the flue 1 again to reduce the sulphur content in the flue gas. It should be noted that the compressed air in the present embodiment can be ejected by the air compressor to achieve a better ejection effect. Of course, other devices capable of ejecting compressed air may be used in communication with the second passage 2, instead of the air compressor, to achieve the same ejection effect.
in addition, in order to improve the discharge amount of atomizing aqueous ammonia in the atomizing chamber 3 to carry out quick conversion to the sulphide, in this embodiment, the one end that atomizing chamber 3 and flue 1 communicate is constructed into the round platform form, and the path end deviates from flue 1 and sets up.

Rotary kiln tail flue gas processing apparatus when using, can adjust the aqueous ammonia quantity according to the condition that sulfur content in the flue gas and kiln tail flue 1 emit the blue light to reach sulfur content's emission standard. Namely, when the sulfur content is discharged to exceed the standard, the amount of the ammonia water flowing into the atomizing cavity 3 and the flow of the compressed air are increased by increasing the control valve 5, so that more ammonia water is atomized and used for reacting with the sulfide in the flue gas. And when the sulfur content reaches the standard, the control valve 5 can be adjusted to be small according to specific use requirements, so that the emission standard is met, and the using amount of ammonia water is reduced.
Of course, depending on the specific use, the control valve 5 can also be provided only on the first channel 4 or on the second channel 2, so as to make a single adjustment of the flow rates of the ammonia and of the compressed air.
