Abstract
The utility model discloses a filtration membrane that is used for industry flue gas one -level to remove dust, include: first gross porosity filter layer, second gross porosity filter layer, membrane supporting layer, first polysulfone (PSO) nanofiber be filter membrane layer and second polysulfone (PSO) nanofiber filter membrane layer in advance, the internal surface of first gross porosity filter layer by interior toward having set gradually outward second gross porosity filter layer the membrane supporting layer first polysulfone (PSO) nanofiber in advance filter membrane layer with second polysulfone (PSO) nanofiber filter membrane layer in advance. In this way, the utility model discloses abundant to the dust filter in the flue gas, it is high to the filtration efficiency of ultrafine dust granule, can improve SOx/NOx control's work efficiency.
Description
Technical field
This utility model is related to filter membrane field, more particularly to a kind of filter membrane for industrial smoke primary dust removing.
Background technology
With China's expanding economy, the environmental pollution bringing in energy-consuming is also increasingly severe.Wherein air cigarette
The destruction of dirt, acid rain, greenhouse effect and ozone layer has become four big killers of harm people's existence.Cigarette contained by coal-fired flue-gas
The harmful substances such as dirt, sulfur dioxide, nitrogen oxides are the main contributors causing atmospheric pollution, acid rain and greenhouse effect.China south
Frequently there is the disaster of acid rain and acid mist in the quite a sheet of region in side and Localities In Southwest.The coal-fired energy obtaining of China reaches energy
More than the 75% of source total amount, and this energy resource structure will not change in recent years.The titanium dioxide meanwhile discharged in coal-fired flue-gas
Sulfur and nitrogen oxides account for the 90% of national total release.It is instant for therefore carrying out desulphurization denitration in China to coal-fired flue-gas
Task.
Flue gas will first carry out pretreatment before desulphurization denitration, however, the pretreatment of current flue gas is to ultrafine dust
The filter efficiency of grain is low, so that having had influence on the denitration desulfurized effect in later stage.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of filter membrane pair for industrial smoke primary dust removing
Dust-filtering in flue gas abundant, high to the filter efficiency of ultrafine dust granule, it is possible to increase the work efficiency of desulphurization denitration.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provides one kind for industrial cigarette
The filter membrane of gas primary dust removing, comprising: the first gross porosity filter layer, the second gross porosity filter layer, film supporting layer, the first polysulfones Nanowire
Dimension pre-filtering film layer and the second polysulfones nanofiber pre-filtering film layer, the inner surface of described the first gross porosity filter layer by interior outward
It is disposed with the second described gross porosity filter layer, described film supporting layer, the first described polysulfones nanofiber pre-filtering film
Layer and the second described polysulfones nanofiber pre-filtering film layer.
In one preferred embodiment of this utility model, the thickness of the first described gross porosity filter layer is more than the second gross porosity mistake
The thickness of filtering layer.
In one preferred embodiment of this utility model, the described thickness of the first polysulfones nanofiber pre-filtering film layer with
The thickness of the second polysulfones nanofiber pre-filtering film layer is identical.
In one preferred embodiment of this utility model, described film supporting layer is ceramic filter film layer.
The beneficial effects of the utility model are: this utility model is abundant to the dust-filtering in flue gas, to ultrafine dust
The filter efficiency of granule is high, it is possible to increase the work efficiency of desulphurization denitration.

2nd, film supporting layer 3, the first polysulfones nanofiber pre-filtering film layer 4 and the second polysulfones nanofiber pre-filtering film layer 5, described
The inner surface of one gross porosity filter layer 1 by interior be disposed with outward the second described gross porosity filter layer 2, described film supporting layer 3,
The first described polysulfones nanofiber pre-filtering film layer 4 and the second described polysulfones nanofiber pre-filtering film layer 5.
In this utility model, the thickness of the first described gross porosity filter layer 1 is more than the thickness of the second gross porosity filter layer 2.
In this utility model, the described thickness of the first polysulfones nanofiber pre-filtering film layer 4 and the second polysulfones Nanowire
The thickness of dimension pre-filtering film layer 5 is identical.
In this utility model, described film supporting layer 3 is ceramic filter film layer.
The beneficial effect that this utility model is used for the filter membrane of industrial smoke primary dust removing is: this utility model is in flue gas
Dust-filtering abundant, high to the filter efficiency of ultrafine dust granule, it is possible to increase the work efficiency of desulphurization denitration.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
