Problems solved by technology
Most of the existing flue gas distributors are simple in structure. When the air flow enters the desulfurization tower, either the flue gas cannot be divided into the above two types of air flow, or the two types of air flow formed cannot achieve a good air flow distribution effect; the result is that the flue gas and The desulfurization droplets cannot be effectively contacted, and the gas-liquid mixing is disordered, which directly affects the desulfurization efficiency, not only wastes materials, but also makes the desulfurization tower equipment easy to scale and damage

The invention relates to a smoke distributor for rotary atomizing desulfurization and a smoke distribution method. The smoke distributor comprises a uniform-pressure wind room arranged on the outer side of a rotating atomizer at the top of a desulfurizing tower, a gradually-shrinking cone-shaped annular airflow channel and a gradually-expanding cone-shaped annular airflow channel, wherein an annular smoke outlet is formed in the inner side surface of the uniform-pressure wind room in the circumferential direction, and a top guide blade group is arranged at the smoke outlet; the gradually-shrinking cone-shaped annular airflow channel comprises an annular airflow channel shrinking towards the inside of the desulfurizing tower, and a guide blade group I is arranged in the gradually-shrinking cone-shaped annular airflow channel in the circumferential direction; the gradually-expanding cone-shaped annular airflow channel comprises an annular airflow channel expanding towards the inside of the desulfurizing tower, and a guide blade group II is arranged in the gradually-expanding cone-shaped annular airflow channel in the circumferential direction. Smoke airflow entering the desulfurizing tower can be redistributed, so that smoke can enter the desulfurizing tower strictly in two paths, turbulence of two kinds of airflow during distribution can be reduced, airflow can be contacted with atomized drops more effectively, accordingly, the desulfurization and purification effects of the smoke are improved, the material utilization rate is increased, and scaling of the desulfurizing tower is avoided.
Description
technical field [0001] The invention relates to the technical field of rotary atomization desulfurization, in particular to a flue gas distributor and a flue gas distribution method for rotary atomization desulfurization. Background technique [0002] Rotary atomization technology has a wide range of applications, including drying, cooling, absorption and flue gas purification. The characteristics of its application in the field of flue gas purification are: the flue gas temperature is medium and low temperature, the flue gas volume is large, the process liquid is large, and the requirements for sanitary conditions are not strict. According to the above characteristics, in order to make the rotary atomization technology have a better effect in flue gas purification, it is necessary to pay attention to the contact conditions between flue gas and process liquid, so that a large amount of flue gas and process liquid can be contacted as effectively as possible. The contact area...
