Description

The filter adsorbent of Purge gas

The invention relates to as the filter of the Purge gas of uses such as cigarette filter tip, anti-poison respirator, air cleaner such as cigarette that elimination is included in cigarette and harmful substances in air used absorbent.

Since the waste gas of the cigarette of cigarette and automobile has been since the report of carcinogen is delivered, the Development and Production of eliminating the filter tip of the harmful substance in the cigarette cigarette and being used for the air cleaner of automobile bodies and factory is developed rapidly.For example cellulose-based fibrous filter tip such as acetylcellulose arranged as what cigarette filter tip used, accompany simultaneously active carbon scheming to improve its attraction performance, and then the also suggestion that has can be in the middle of cellulose-based fibrous filter tip and above-mentioned active carbon or press from both sides boiomacromolecule materials such as serum protein, lactalbumin, egg albumin, yeast nucleic acid separately in this cellulose-based centre fibrous with filter tip.

; use the cellulose fibre shape with filter tip and press from both sides therebetween aspect the cigarette filter tip of active carbon having only; though eliminate effect for the absorption that tar and nicotine have to a certain degree; for come on the scene as the carcinogen in the cigarette cigarette in recent years 3; 4-ring-type hydrocarbon but can't be eliminated at all in absorption; though adopt the boiomacromolecule material to press from both sides the middle way of into cellulose-based fibrous filter tip to 3 separately or with above-mentioned active carbon in addition; 4-ring-type carbonization Hydrogen Energy demonstrates attraction performance to a certain degree, but its attraction performance can't be satisfactory.

It is a kind of for multiple harmful substances that purpose of the present invention is intended to provide, particularly 3,4-ring-type hydrocarbon can be brought into play attraction performance preferably, is suitable at the filter tip of filter-tip partly and be loaded on the absorbent of the cigarette filter thing that uses in the tobacco pipe, anti-poison respirator, air cleaner etc.

In addition, another object of the present invention is to provide and contain drying and make the cyanophycear absorbent of pulverous conveyor screw.

And then another purpose of the present invention is to provide with above-mentioned conveyor screw blue algae and cooperates pulverous carrier to form granular absorbent separately or again.

Used in the present invention is dark green conveyor screw blue algae, and general length is 300～500 μ m, and thick about 8 μ m are extremely large-scale hair shape frond, and generally all contains and account for the more protein of weight 64.2～72.6%.

This conveyor screw blue algae be after obtaining in about 120～130 ℃ rapidly drying do for 3～10 seconds Powdered, and the dry powdered conveyor screw blue algae of this state, its protein amount normally accounts for about 60% of weight.Though can directly use it as absorbent or as the Main Ingredients and Appearance of absorbent, also can adopt method such as alcoholic extraction to remove pigment, the protein amount bring up to account for weight 70% after just use.

Flat dry pulverous conveyor screw blue algae of adopting the said method gained except can be directly separately or and other Powdered carriers mix use as Powdered absorbent, also can be mixed and made into graininess big and porous graininess absorbent use separately or with other Powdered carriers as surface area.

As the Powdered carrier that matches with above-mentioned dry powdered conveyor screw blue algae, preferably comparatively desirable for the material that various harmful substances have attraction performance with himself.That for example can adopt has active carbon, zeolite, alumina, silica gel, atlapulgite, ion exchange resin, enzyme, crosses charcoal hydrochlorate, perborate, peroxidating pyrophosphate or the like, and comparatively ideal is active carbon, zeolite, alumina, silica gel and atlapulgite.

In addition, as above-mentioned dry powdered conveyor screw cyanophycear separately or and other Powdered carriers be mixed and made into the method for granular absorbent, though can adopt original known granular preparation method, but in liquid such as water, alcohol, allow it suspend with suitable binders such as dextrin, paste, carboxy methyl celluloses to adopt, and then be mixed into pasty state after carrying out spray-dired method or reducing the use amount of liquid such as water, alcohol, while extrude the method cutting off and carry out drying for well from ozzle again.

The absorbent that forms with said method, except can allow pay the fiber filter of cigarette suction inlet chew with other absorbent, be contained in fiber filter in the cigarette holder chew with other absorbent, be installed in the deodorant that the gas permeability fiber body structure that uses in anti-poison respirator and the air cleaner and synthetic resin continuous air bubbles foaming body or other absorbent load hold in the paper bag body that can also be filled in gas permeability the use as refrigerator etc. and use.

Followingly the filter absorbent of the present invention's Purge gas is specified according to embodiment.

Embodiment 1
