Problems solved by technology

It requires a lot of water circulation and adding chemicals in the water. This kind of filtration method has high operation and maintenance costs. Many small enterprises will directly discharge the filtered water, which will cause re-pollution of the water source.
[0005] Therefore, the current spraying industry lacks filter materials that can effectively reduce actual industrial pollution and at the same time allow environmental protection costs to be accepted by most companies

Embodiment 1

[0047] Embodiment 1, a kind of preparation method of filtering paint mist environmental protection filter material, comprises the following steps:

[0048] S1: Prepare materials, use 4Kg low melting point fiber and 5Kg3D fine fiber as raw material A for making the basic filter layer, 3Kg low melting point fiber, 3Kg30D fiber and 1Kg 3D fiber as raw material B for the embossed filter layer;

[0049] S2: Material molding, put two parts of raw material A into the first opener and the third opener respectively, and add one part of raw material B into the second opener for uniform mixing and removal of impurities;

[0050] S3: Storing materials, transporting two parts of raw material A and one part of raw material B to the first, third and second cotton mixing boxes respectively through the wind force of the wind turbine for mixing;

[0051] S4: carding processing, two parts of raw material A and one part of raw material B are transported to corresponding first, third and second ca...

Embodiment 2

[0059] Embodiment 2, a kind of preparation method of filtering paint mist environmental protection filter material, comprises the following steps:

[0060] S1: Prepare materials, use 5Kg low melting point fiber and 6Kg3D fine fiber as raw material A for making the basic filter layer, 5Kg low melting point fiber, 6Kg30D fiber and 4Kg 3D fiber as raw material B for the embossed filter layer;

[0061] S6: Lay the fiber web C evenly on the bottom curtain of the web-laying machine through a flat-laying machine to form a 3cm-thick flat-type fiber layer 1, and then lay the fiber web D to a height through the vertical web-laying machine The vertical fiber web layer 2 with a thickness of 7 cm is first placed on the bottom layer of the flat fiber layer 1 made of fiber web C through the bottom curtain, and then the vertical fiber web layer 2 made of fiber web D is placed on the flat surface. On the top of the paved fiber layer 1, the fiber web E is evenly laid out with a 3cm thick flat f...

Embodiment 3

[0063] Embodiment 3, a kind of preparation method of filtering paint mist environmental protection filter material, comprises the following steps:

[0064] S1: Prepare materials, use 4.5Kg low melting point fiber and 5.5Kg3D fine fiber as raw material A for making the basic filter layer, 4Kg low melting point fiber, 4.5Kg30D fiber and 2.5Kg 3D fiber as raw material B for the embossed filter layer;

Abstract

The invention discloses an environment-friendly filter material for filtering paint mist. The environment-friendly filter material comprises multiples layers of tiled fiber layers arranged in parallelwith each other and multiples vertical fiber mesh layers perpendicular to the tiled fiber layers. One end of the vertical fiber mesh layer is fixedly connected to the tiled fiber layer. One end, faraway from the tiled fiber layer, of the vertical fiber mesh layer has a structure with surface concaves and convexes alternate with each other so that the filtration area is increased, the accumulation amount of the paint mist is increased and the special requirements on paint mist filtration are further satisfied.

Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to an environment-friendly filter material for filtering paint mist and a preparation method thereof. Background technique [0002] In the environment where the greening of industrial production is advocated all over the world, how to reduce the emission of various harmful gases in industrial production is a problem that must be considered in various fields. For the traditional spraying industry, this problem is even more serious, because during the spraying process, a large amount of paint mist will escape to the outside with the flow of air, causing pollution to the external environment. [0003] At present, in the spraying industry, two kinds of filtration methods are usually used to filter the paint mist. One of them is dry filtration. Dry filtration usually uses glass fiber as the main material of the filter screen. Glass fiber production requires glass raw materials to...
