With reference to the actual conditions of aluminium alloy production and processing factory material and processing step are handled from the most suitable.Through in the utility model
Aluminium alloy producing line waste gas after processing unit is purified can reach the standard directly discharged, and any dirt will not be caused to environment
Dye, and processing cost is low, and economy is high.
The utility model technique effect to be reached is realized by following scheme：
Aluminium alloy producing line emission-control equipment in the utility model includes device case, air inlet and gas outlet；It is described
Acid gas/alkali gas filter layer, ozone lamp, dried filtering layer, uviol lamp, thick is sequentially provided with device case from air inlet to gas outlet
Filtering layer and fresh air filter layer；The coarse filtration layer is glass fiber filters, and the fresh air filter layer is activated carbon filter layer.
Further, the acid gas/alkali gas filter layer is to be soaked with alkali lye or the cotton filter layer of acid solution.Preferably, institute
It is limewash to state alkali lye, and the acid solution is acetum.
Further, the dried filtering layer is hygroscopicity resin layer.Preferably, it is compounded with light in the dried filtering layer
Catalyst filter screen.
Further, the glass fiber filters are glass fibre pocket type filter.
Further, used in the activated carbon filter layer for cocoanut active charcoal.
Further, the air inlet and gas outlet are set to bucket-shaped structure.
Further, air intake wind speed is 3-5m/s in the emission-control equipment.
The utility model has advantages below：
1st, the utility model provides a kind of emission-control equipment for aluminium alloy producing line, and the processing unit is closed for aluminium
Acid mist, alkali mist and other harmful substances in golden producing line waste gas are handled, and combine the reality of aluminium alloy production and processing factory
Border situation is from processing material the most suitable and processing step.
2nd, the filter layer in the utility model emission-control equipment uses restored acid liquid in aluminium alloy producing line, alkali lye to carry out
Processing, filtering material are also carried out using material simple and easy to get, make processing cost very low, practical.
Brief description of the drawings
Fig. 1 is the structural representation of aluminium alloy producing line emission-control equipment in the utility model.
Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Aluminium alloy producing line emission-control equipment in the present embodiment as shown in Figure 1, arrow in gas inlet direction such as accompanying drawing
Shown in head direction.
Aluminium alloy producing line emission-control equipment in embodiment includes device case 102, air inlet 101 and gas outlet 109.
Be sequentially provided with from air inlet to gas outlet in device case acid gas/alkali gas filter layer 103, ozone lamp 104, dried filtering layer 105,
Uviol lamp 106, coarse filtration layer 107 and fresh air filter layer 108.Coarse filtration layer is glass fiber filters, and fresh air filter layer is activated carbon
Filter layer.
Firstly the need of what is be disposed off it is acid mist or alkali mist in waste gas, acid mist or alkali mist in aluminium alloy producing line waste gas
Generation it is relevant with aluminum alloy surface handling process, such as using the descaling technique of highly acid, surface with chemical polishing technology, anodic oxygen
Chemical industry skill etc., there will be a certain amount of acid gas in waste gas, otherwise alkaline waste gas is then also easy to produce using the technique for including highly basic.
In the utility model, highly acid or the composition of strong basicity are removed using acid gas/alkali gas filter layer first at air inlet, acid
Gas/alkali gas filter layer is to be soaked with alkali lye or the cotton filter layer of acid solution.Cotton filter cloth is a kind of cheap filter material
Material, it is cheap and easily-available, and cotton good hygroscopicity, moisture absorption degree is easy to control, cotton filter cloth is pressed into cotton filter layer, then
Alkali lye or acid solution are drawn, is just used on the acid mist or alkali mist removed in waste gas.The alkali lye used in this step is preferably stone
Buck, acid solution are acetum, are cheap material.Finished once the alkali lye or acid solution in cotton neutralize,
Again make alkali lye or acid solution, the use of its absorption addition very simple.
The waste gas of acid mist or alkali mist composition is removed in the presence of ozone lamp 104, the partial organic substances included in waste gas
Decomposed, while serve the effect of preliminary purification.On the one hand waste gas removes moisture, the opposing party into dried filtering layer 105
Face coarse filtration falls the dust granules of bulky grain, in order to avoid producing interference effect to subsequent purification, dried filtering layer is hygroscopicity resin layer.
Waste gas main harm thing after the processing of uviol lamp 106 is organic molecule gas, such as carbon containing organic of nitrogen oxides, sulfur-bearing
Gas, therefore in the present embodiment by composite photo catalyst filter screen in dried filtering layer, accelerate catalyst nox, sulfur-bearing is carbon containing has
The decomposition of machine gas.After question response, the waste gas after the 107 pairs of processing of coarse filtration layer is completely filtered, and is removed residual in waste gas
Small particle particulate and the liquid residual stayed, fresh air filter layer 108 then adsorb last residual particles and organic matter, make finally to discharge
The gas gone does not have unpleasant temperature.
Coarse filtration layer preferably uses glass fibre pocket type filter, and filter efficiency is high and easy to use, and fresh air filter layer is preferred
Using cocoanut active charcoal filter layer, organic matter best results are adsorbed.To reach optimal treatment effect, air inlet and gas outlet are set
For bucket-shaped structure, it is big that air inlet is set to the small outlet of entrance, and it is small that gas outlet is set to entrance large outlet, effectively increases pending gas
Residence time in emission-control equipment, it can also avoid escape of the gas in air inlet and gas outlet.For up to optimization process
Effect, air intake wind speed is 3-5m/s to pending waste gas in emission-control equipment in the utility model.
The utility model provides a kind of emission-control equipment for aluminium alloy producing line, and the processing unit is directed to aluminium alloy
Acid mist, alkali mist and other harmful substances in producing line waste gas are handled, and combine the reality of aluminium alloy production and processing factory
Situation is from processing material the most suitable and processing step.Filter is simply easy in the utility model emission-control equipment
, cost it is cheap, practical, be adapted to promote the use of in aluminium alloy manufacturing industry.Enter through processing unit in the utility model
Aluminium alloy producing line waste gas after row purification can reach the standard directly discharged, and any pollution will not be caused to environment, and locate
It is low to manage cost, economy is high.
It is last it should be noted that above example is only illustrating the technical scheme of the embodiment of the present invention rather than it is entered
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, one of ordinary skill in the art
It should be understood that can still be modified to the technical scheme of the embodiment of the present invention or equivalent substitution, and these modifications or wait
