Description
Technical field
The present invention relates to a kind of exhaust-gas treatment frock, specifically a kind of green starch packaging special exhaust gas mistake of film preparation
Filter frock.
Background technology
Built up membrane is usually plastic polymer, its production process and product abandonment thing can all cause natural ecological environment
Huge destruction, and it is all oil product to produce raw material used in such film, is non-renewable resources.Natural plant starch
Compared as packaging membrane material with artificial synthesized polymer film, starch packaging film has nontoxic, environmentally protective, energy biology
The advantages that degraded.But plant amylum is crushed and other reactants due to needing in the process of production starch packaging film
Mixing is stirred, the exhaust gas produced in process of production can be doped with dust particles, if being directly discharged in air to make
Into air pollution, therefore it is directed to the waste gas produced research and development for recycling of green starch packaging film preparation and is increasingly subject to
The concern of people.
The content of the invention
The present invention proposes a kind of special exhaust gas filtering frock of green starch packaging film preparation, the frock regarding to the issue above
By a variety of different filter layers, particulate matter in exhaust gas can be effectively filtered, avoids particulate matter from causing dust pollution into air.
Specific technical solution is as follows：
A kind of special exhaust gas filtering frock of green starch packaging film preparation, it is characterised in that including filtering tool shell, the mistake
It is in unfilled corner cube structure to filter tool shell, and filtering one side bottom of tool shell is equipped with air inlet, the filtering frock shell
Gas outlet is equipped with the top of body opposite side, gas outlet described in the air inlet is inclined to set；The filtering frock housing bottom
Equipped with support feet；The filtering frock enclosure interior is provided with four filter screens, includes first successively from air inlet to gas outlet
Filter screen, the second filter screen, the 3rd filter screen and the 4th filter screen, four filter screens are in incline in the filtering frock
Tiltedly set, in arranged in parallel, four filter screens and bottom in the filtering tool shell between four filter screens
Face is in that included angle A is 45 degree；Size, the shape of first filter screen are identical with the 4th filter screen, second filtering
Size, the shape of net are identical with the 3rd filter screen；All it is evenly arranged with four filter screens and is provided with filter hole, institute
Filter hole on the first filter screen and the filter hole structure triangular in shape on the 3rd filter screen are stated, on second filter screen
Filter hole is in regular hexagon structure with the filter hole on the 4th filter screen；The aperture of filter hole is on first filter screen
40-80 mesh, the aperture of filter hole is 100-150 mesh on second filter screen, filter hole on the 3rd filter screen
Aperture is 200-250 mesh, and the aperture of filter hole is 300-400 mesh on the 4th filter screen.
Further, the housing is equipped with chamfering at air inlet and at gas outlet.
Further, the support feet quantity is 4, is uniformly arranged on the housing bottom surrounding, the support feet is in
Rectangular parallelepiped structure, in being vertically arranged.
Further, the aperture of filter hole is 50-60 mesh on first filter screen.
Further, the aperture of filter hole is 120-140 mesh on second filter screen.
Further, the aperture of filter hole is 220-240 mesh on the 3rd filter screen.
Further, the aperture of filter hole is 330-370 mesh on the 4th filter screen.
Compared with the prior art, beneficial effects of the present invention are：Multiple times of filtration is carried out using multi-filtering net, from air inlet
To the first filter screen that gas outlet uses to the aperture of the 4th filter screen from large to small, particulate matter can be filtered by several times according to size,
Filter efficiency is lifted, improves using effect.Filter hole on first filter screen is in the filter hole on the 3rd filter screen
Triangular structure, its triangular shaped stabilization, service life are high；In filter hole and the 4th filter screen on second filter screen
Filter hole be in regular hexagon structure, multiple regular hexagons are arranged in honeycomb structure, and force stability is high.
Since packaging film is stirred in reaction process with heating process, the exhaust gas in its reaction process out is mostly heat
Gas, hot gas can hoist flowing from lower, therefore air inlet is positioned over bottom by the housing of special designing, and gas outlet is put
Top side is placed in, can be good at the characteristic risen using gas so that gas is automatically from the first filter screen to the 4th filtering
Net flowing, improves filter effect.
