The utility model also provides a kind for the treatment of process of the Environmental-protecting dust-removing equipment for Copper making, and detailed process is as follows:
a:Containing least a portion of sulfide, fluoride in the flue gas that smelting furnace 21 discharges, by 8 He of the first deduster host
Treated that flue gas enters that the mating shared rotational flow and spray desulfurizing tower 5 of rear class carries out for the bag filter of second deduster host 10
The processing of water spray alkali desulphurization；
b:Newel is arranged in 5 inside of desulfurizing tower, and configures 1 layer of spiral board layer, after so that flue gas is tangentially entered from king-tower bottom
Helically rise, increases the time and distance that flue gas is contacted with water mist；Two layers of spray system is set in tower, using 1 cun of heavy caliber
Silicon carbide hollow cone atomizer, one 22KW anticorrosive anti-wear horizontal pump of every layer of use individually supply water, and dust removing effects is made to reach
Most preferably, setting stainless steel Z-type in king-tower top efficiently blocks water demister, and the net gas containing a large amount of steam after atomization process is flowing
When through demister, steam is prevented from, and net gas is discharged, and the phenomenon that coloured soot emissions never occurs in entire production process,
Since flue gas acidic substance content is less, the dispensings such as corrective such as alkali, ammonia, calcium carbonate are also relatively fewer, therefore recirculated water PH
Manual material feeding holding may be used in value holding, and cascade spinning-board tower configures two sets of circulated sprinkling water pumps, one is enabled when air quantity is smaller
Platform water pump enables two water pumps when air quantity is larger, alkali is neutralized using manual launch, and byproduct is no longer matched also due to output is less
Set the byproducts corollary equipments such as tower external oxidation pond, vacuum belt rotary vacuum filter；
c:Periodically timing a certain amount of dry powder can be sprayed into babinet when automatic injection apparatus operation, so that deashing is thorough
Bottom promptly sprays into a large amount of dry powder, can put out fire to a certain extent when occurring that dust combustion or filter bag burn in babinet
Star, fire hydrant top of the box and around spray cooling, prevent box deformation.Make intensity of a fire nature due to anoxic in babinet
Extinguish, the loss and consequence that explosion is brought can be reduced to the greatest extent.
The technique effect and advantage of the utility model：By being equipped with dust-extraction unit, contain in the flue gas of smelting furnace discharge few
Partial sulfide, fluoride, by the first deduster host and and the flue gas after deduster host process enters rear class and matches
The shared rotational flow and spray desulfurizing tower of set carries out water spray alkali desulphurization processing, is discharged into after removing most of water mist using demister
Air, since flue gas acidic substance content is less, the dispensings such as corrective such as alkali, ammonia, calcium carbonate are also relatively fewer, therefore recycle
Manual material feeding holding may be used in water ph value holding, the phenomenon that coloured soot emissions never occurs in entire production process, leads to
Cross and be equipped with multiple gravity explosion-proof valves, automatic injection apparatus and fire hydrant, when the operation of automatic injection apparatus can periodically timing to
A certain amount of dry powder of injection in babinet, it is urgent to spray into when dust combustion or filter bag burn in generation babinet so that deashing is thorough
A large amount of dry powder, can put out Mars to a certain extent, fire hydrant top of the box and around spray cooling, prevent case
Body deforms, and the intensity of a fire is made to extinguish naturally because of anoxic in babinet, can reduce loss and consequence that explosion is brought to the greatest extent.
Embodiment two, what is different from the first embodiment is that the first deduster host 8 and the second deduster host 10 are internally provided with
Another set of temperature control system：
Temperature control uses automatic control system, by PLC+ temperature controllers+temperature measuring probe+pneumatic control air-valve group
At control flow uses two temperature controller（Detection probe containing two temperature）, the end of 1# temperature controllers control multitube cooler
End and the end of bypass pipe, 2# temperature controllers control cold blast sliding valve, and the flue-gas temperature due to entering filter bag necessarily is greater than dew point, with
Generation condensed water is avoided to cause to paste bag, therefore system default flue gas enters bag filter from by-pass line.It is set when temperature is higher than
When setting temperature, the channel of multitube cooler is opened, closes by-pass line, so that flue-gas temperature is laggard by multitube cooler cooling
Enter bag filter；When temperature drops to setting temperature, the channel of multitube cooler is closed, by-pass line is opened, makes flue gas
Temperature quickly improves.With the above arrangement, the temperature into bag filter is made to control always in a controllable wave band.Make
Bag filter operation is more stable.Such as because of special operation condition, flue gas moment overtemperature, cold and hot pipeline switching cannot make bag filter into
The temperature in air port is controlled in the resistance to temperature of filter bag（170℃）Cold cooling is mixed hereinafter, should quickly open cold blast sliding valve and carry out cold wind, works as flue gas
Temperature it is back to normal and be reduced to setting temperature after, cold blast sliding valve is automatically closed.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
Equivalent replacement is carried out, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
