Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
A kind of spray as shown in Figures 1 to 3 scatters tower, including tower body 1, chimney 2, flue outlet 3, demister 4, particulate matter
Blocking apparatus 5, the stage casing inner cylinder 6 along the setting of 1 inner wall of tower body, the flue entrance 7 on 1 wall surface of tower body, the spray equipment in middle storehouse
8, the diffuser 9 under middle storehouse, the uptake flue 60 of connection upper storehouse and lower storehouse, the absorption liquid pool 10 in lower orlop portion, absorption liquid pool 10
The interior overflow port 12 connect on oxidation fan oxygen-supplying tube 11 and absorption liquid pool 10 at liquid level.
As shown in Fig. 2, in needing the flue gas purified to enter first by flue entrance 7 in storehouse, and sprayed by spray equipment 8
The spray liquid spilt increases humidity to flue gas, flue-gas temperature is dropped to chemical reaction required temperature, while flue gas uniformly being distributed
Into multiple diffusers 9, the preliminary trapping to the fine grained pollutant in flue gas and preliminary desulfurization and denitration to flue gas are completed,
Diffuser 9 is mounted below middle storehouse and is connected to lower storehouse, and is inserted into the absorption liquid pool 10 in lower storehouse, and therefrom storehouse passes through air-dispersing to flue gas
Pipe 9 enters directly into the absorbing liquid in lower storehouse, and is gushed to floating by absorbing liquid in the form of tiny bubble, and absorbing liquid is to flue gas
In SO2 and NOx carry out mass transferring in gas phase, while absorbing the oxidation fan oxygen-supplying tube 11 that connects in liquid pool 10 can be by the Asia in flue gas
Salt etc. is oxidized into normal salt, flue gas is floating gush during complete deep purifying to flue gas, i.e.,：Fine dedusting to flue gas
It falls off with depth and denitration, flue gas enters upper storehouse by uptake flue 60 again, removed through particulate matter blocking apparatus 5 and demister 4
After the moisture carried secretly in salt fog, PM2.5 atmosphere pollution below and flue gas, clean flue gas is by 7 qualified discharge of flue outlet
Into air.
Multiple diffusers 9 are connected below middle storehouse, flue gas enters absorption liquid pool in a manner of multi-passage circulating along diffuser 9
In 10, flue gas influx increases, and explosive flue gas can be handled with fast purification, and diffuser 9 is extended to and absorbed in liquid pool 10
Layer or lower layer position, the time of flue gas residence in a liquid is longer when flue gas is gushed to liquid level is floating, and the contact of gas-liquid is more abundant,
So that smoke gas fine dedusting and depth is fallen off and reaches best with denitration.
Particulate matter blocking apparatus 5 is that aerosol and ease ammonia blocking apparatus, such as PM2.5 that can be handled in flue gas are below
Atmosphere pollution, it is more preferable to the purified treatment effect of particulate matter in flue gas.
Oxidation fan oxygen-supplying tube 11 is connect at least provided with two sections absorbing in liquid pool 10, is to ensure the oxygen of oxygen-supplying tube discharge
Change gas and be more than or equal to exhaust gas volumn, keeps the reaction of oxidizing gas and flue gas sufficient, avoid oxidizing gas content deficiency flue gas
It cannot be purified completely, occur omitting flue gas.
Overflow port 12 is equipped at liquid level on absorbing liquid pool 10, the liquid level for absorbing liquid pool 10 can be monitored and controlled,
Limitation liquid level is more than to prevent liquid from releasing.
The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art
Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
Range.
