Abstract
The utility model discloses a kind of polymeric meltblown superfine fibre and the composite spunlaced filter felt of dry-laid non-woven cloth, and polymer forms superfine fibre net through melt-blown, and superfine fibre net is reinforced through spun lacing with dry-laid non-woven cloth and is combined into filter felt.The utility model has the advantages that with high efficiency filter feature, melt-blown micro fibre layer has smaller space, can intercept smaller dust granules；Service life is long.
Description
Technical field
The utility model be related to it is a kind of be used to filtering the filter felt of flue gas, more particularly to a kind of polymeric meltblown superfine fibre with
The composite spunlaced filter felt of dry-laid non-woven cloth.
Background technology
With the raising of Environmental pollution problem attention degree, existing air pollution emission standard requires tighter
Lattice, the Atmospheric particulates emission limit of every profession and trade is commonly 30-50mg/m3.China's electric power, steel, the bulky grain thing weight of cement three
Pollution industry has put into effect more strict and discharge standard in succession, and it is necessary to have the filter felt of higher filter efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide for a kind of ultra-fine fibre of the good polymeric meltblown of filter effect
Dimension and the composite spunlaced filter felt of dry-laid non-woven cloth.
In order to solve the technical problem of the above, the utility model provide a kind of polymeric meltblown superfine fibre and dry method into
The composite spunlaced filter felt of net non-woven cloth, polymer forms superfine fibre net through melt-blown, superfine fibre net with dry-laying is non-knits
Make cloth and be combined into filter felt through spun lacing reinforcing.
Filter felt of the present utility model includes the superfine fibre layer on upper strata and the dry-laid non-woven cloth of lower floor, upper strata
Superfine fibre layer filtration, the non-woven cloth of lower floor provides the strength support of filter felt.
Superior effect of the present utility model is：
1）The utility model has high efficiency filter feature, and melt-blown micro fibre layer has smaller space, can intercepted smaller
Dust granules；
2）The utility model is reinforced using spun lacing, makes filtrate product surface finer and close, will not be damaged while spun lacing is reinforced
Fiber, enables fiber preferably to keep its physical and chemical performance, improves life of product.
Brief description of the drawings
The Figure of description for constituting the part of the application is used for providing further understanding to of the present utility model, this practicality
New schematic description and description is used to explain the utility model, does not constitute to improper restriction of the present utility model.
In the accompanying drawings：
Fig. 1 is structural representation of the present utility model；
Label declaration in figure
1-superfine fibre net；2-dry-laid non-woven cloth.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Describe embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
Fig. 1 shows the structural representation of the utility model embodiment.As shown in figure 1, the utility model provides one kind
Polymeric meltblown superfine fibre and the composite spunlaced filter felt of dry-laid non-woven cloth, polymer form superfine fibre net through melt-blown
1, superfine fibre net 1 is reinforced through spun lacing with dry-laid non-woven cloth 2 and is combined into filter felt.
Filter felt of the present utility model includes the superfine fibre layer 1 on upper strata and the dry-laid non-woven cloth 2 of lower floor, upper strata
Superfine fibre 1 filtration of layer, the strength that the non-woven cloth 2 of lower floor provides filter felt supports.
First processing is dried in polymer by the utility model, through screw extruder, spinning head spinneret production superfine fibre；
Then superfine fibre net melt-blown obtained is reinforced with dry-laid non-woven cloth through spun lacing；Last drying and shaping, obtains spun lacing
Filter felt.
Preferred embodiments of the present utility model are the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
