Description
Technical Field
The utility model relates to an air purification equipment technical field, more specifically say, in particular to honeycomb filter paper and a honeycomb filter core and an internal-combustion engine air supply system.
Background
For enterprises producing honeycomb filter elements, it is a goal of the enterprises to produce filters with low resistance and high dust holding capacity. The low resistance and high dust holding capacity are expressed as follows: 1. on the premise of the same size (same volume) of the filter element, the area of the filter paper is increased, so that the purpose of increasing the dust holding capacity of the filter element is achieved; 2. on the premise of the same air quantity, the smaller the pressure difference of the filter element (the difference between the pressure at one end of the air inlet and the pressure at one end of the air outlet) is, the better the filter element is.
At present, common honeycomb filter element filter paper in the market is corrugated structure, including corrugated filter paper a (wave paper structure) and flat filter paper b (plane paper structure), and the bonding mode between corrugated filter paper a and the flat filter paper b has two kinds:
referring to fig. 1, fig. 1 is a schematic structural view of a honeycomb filter element after splitting a corrugated filter paper and a flat filter paper. Fig. 1 mainly shows a first adhering method of the corrugated filter paper and the flat filter paper described below.
Firstly, uniformly coating a plurality of hot melt adhesives c (the length direction of the hot melt adhesives c is vertical to the depth direction of a corrugation) on a flat-plate filter paper b at certain intervals along the direction (vertical to the corrugation direction on the corrugated filter paper a) vertical to the corrugated filter paper a, and bonding the corrugated filter paper a and the flat-plate filter paper b together in such a way;
secondly, an adhesive is continuously applied to the bottom of the corrugated filter paper a, thus bonding the corrugated filter paper a and the flat filter paper b together.
The first bonding method has the advantages that: the air entering the filter element can freely flow in the whole filter element space (between the corrugated filter paper a and the flat filter paper b), so that the wind resistance can be reduced, all the filter paper is uniformly subjected to dust, and the dust holding capacity is improved. The disadvantages are: the corrugated filter paper a and the flat filter paper b are bonded in a point mode, the connection strength is low, so that the support force of the corrugated filter paper is insufficient, the corrugated filter paper has a collapse risk under certain wind resistance, once the corrugated filter paper collapses, an original flow channel of the corrugated filter paper is blocked, the area of the filter paper in the part is invalid, the filter paper becomes an invalid filter area, and therefore the dust holding capacity is reduced and the resistance is increased.
In the second bonding method, the bonding between the corrugated filter paper a and the flat filter paper b is line connection, so that the original corrugation can be guaranteed to have enough supporting force, the risk of collapse of the corrugation is avoided, and all the unfolded areas are effective areas. However, in the second mode, because the linear connection is adopted, each flow channel is independently formed, air cannot freely flow in the whole filter element, and the running resistance of the filter element is large.
