Operation principle of the present utility model is：According to the effect of the absorption affinity of liquid and centrifugal force so that liquid can liquid
Each blinds surface can be paved with automatically, make each blade（182）Everywhere surface all form dynamic liquid film so that liquid expose
Largest surface area, the chance contacted with gas just maximizes, the quick rotation on blade face in addition, but several times add and gas
The touch opportunity of body, and with gas what is contacted is all new liquid film, substantially increases effective processing to gas；Meanwhile
By blade（182）Above-below direction louvered is made, the blinds of adjacent louvered air drain is opened in the opposite direction so that pass through blinds
The flow perturbation of air drain is stronger, increases time of contact and the area of gas and liquid level again；In addition, by setting up each treatment region
Independent loops system, acted on, realized to the multi-functional integrated treatment of gas with completing the processing different to gas.
The utility model is vertically swept away, strong stirring, new liquid contact, multiple impact, gas as a result of dynamic liquid film
Effective processing time length in tower, thus it is high to the treatment effeciency of gas, and processing is thorough.As long as flue gas flow rate design is reasonable,
Resistance of the gas in tower is very small.Gas flow rate is more much higher than the gas flow rate of general spray Deethanizer design, according to tower height and tower
Intra vane（182）Series can meet gas flow rate more than 10 meters/it is per second more than, therefore treatment effeciency is very high, processing unit ratio
Conventional process mode is much smaller.
Treatment fluid in the utility model sprays without being atomized, major diameter outlet, as long as spraying the blade for flowing to rotation
（182）It is upper, prevent the failure that traditional atomising device treatment fluid blocks atomizer.As long as treatment fluid spray volume meets
Rotating vane（182）On be completely formed liquid film, the effect of efficient process can be just realized to gas.
Easily realization is handled gas multifunctional all the utility model, such as fume treatment to coal-burning boiler, from
It can realize that the multifunctional disposable such as dedusting, desulfurization, out of stock, dehydration, recuperation of heat is handled on down, ring is installed additional in different process levels
The equipment such as shape drip tray, filtering that supporting level needs, dosing, forms this grade of function self-circulation system, multistage multi-functional order
Superposition, flue gas enter a tower and complete whole processing functions, realize qualified discharge.Gas treatment flow is short and simple, whole process processing
Resistance is greatly reduced, and can reduce air inducing unit power, and the vertical installation of equipment accounts for day and do not taken up an area, and gas lift is rationally direct, pipeline letter
Change.The utility model greatly reduces the occupation of land and fund input of fire coal boiler fume afterbody processing equipment.Due to every grade of place
Reason is all independent and extremely efficient, whole course integration, therefore easily reaches the flue gas minimum discharge standard of national regulation, runs into
This also has larger reduction than traditional flue gas processing device.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
