Abstract
The utility model relates to an activated carbon poison protective gauze mask, comprising a filter layer, lacing holes, lacings, a plain bag, a spacer layer, the activated carbon. The utility model has the advantages of low cost, long poison protective time, good poison protective effect, convenient and comfort use, simple manufacturing process. The utility model is suitable for various situations with toxic substances in the air, and the utility model is especially suitable for jobs with low concentration toxic works.
Description
The utility model belongs to the gas defence utensil, is specifically related to a kind of software active carbon anti-poison respirator, is applicable to the various occasions that have noxious material in the air.
Existing anti-poison respirator generally is also referred to as breathing mask, generally includes a thin rubber face shield, connects the coiled pipe of one section weak point above, and the pipe tail connects a medicinal cupping.Or on face shield, directly connect one or two little medicine box.Active carbon is placed in the medicine box, to various toxic gases and steam suction-operated in various degree, realizes the function of filter poison by active carbon.This anti-poison respirator weight is big, cost height, inconvenience when wearing, uncomfortable, not attractive in appearance, be difficult to accept for people, use in the post that is unsuitable for the low concentration harmful work especially, at the shortcoming of above-mentioned anti-poison respirator, the someone has invented a kind of anti-poison respirator that utilizes carbon fiber to make, and this anti-poison respirator is attractive in appearance, comfortable wearing has the function of protection low concentration toxic gas.But carbon fiber is in light weight, and adsorbance is limited, adsorption rate low (being not more than 20%), and generally when benzene during at 100PPM, protection time is no more than 20 minutes, and cost is still higher.
The purpose of this invention is to provide a kind of improved anti-poison respirator, it not only can protect the toxic gas of humble concentration, and compares with existing mouth mask and to have in light weightly, and price is low, comfortable wearing, and pattern is attractive in appearance, the advantage that protection time is long.
The purpose of this utility model is achieved in that software active carbon anti-poison respirator of the present utility model comprises that there is the packed filtering material in plane the centre of filter course, frenulum hole, frenulum, filter course.
The filtering material of software active carbon anti-poison respirator of the present utility model is the active carbon of fine particulate, and said plane bag is a software, is made by nonwoven, has in the bag of plane the equally distributed separate layer of active carbon.
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is a view in transverse section of the present utility model
(1) is filter course among the figure, is made by gauze, and (2) are the frenulum hole, and (3) are frenulum, and (4) are the plane bag, are made by nonwoven, and (5) are separate layer, is also made by nonwoven, and (6) are the fine grained active carbon.
The manufacturing process of the utility model active carbon anti-poison respirator is as follows: at first, make plane bag through heat seal with nonwoven with separate layer, active carbon is filled in the septated hole that is separated out by separate layer, then that the plane bag is bonding, pack in the filter course that makes, make active carbon anti-poison respirator of the present utility model with frenulum hole.
Filtering material of the present utility model can be selected according to environment requirement, can select active carbon to organic compound steam, can select soda lime to acid mist, can select copper sulphate to ammonia, can select " blocking suddenly ", can select to contain the iodine active carbon mercuryvapour to carbon monoxide.
Active carbon anti-poison respirator of the present utility model, gas defence is effective, and protection time is long, and cost is low, manufacture craft is simple, and is easy to use, comfortable wearing, attractive in appearance, and the adsorption rate to benzene is 49% after tested, when benzene during at 100PPM, protection time was greater than 8 hours, and inspiratory resistance is less than 15 millimeters water.
Claims (2)
1, a kind of active carbon anti-poison respirator comprises filter course (1), frenulum hole (2), frenulum (3), and there is the filtering material of plane bag (4) dress the centre that it is characterized in that filter course.
2,, it is characterized in that filtering material is the active carbon (6) of fine particulate as said active carbon anti-poison respirator in the claim 1.Said plane bag (4) is a software, is made by nonwoven, has the equally distributed separate layer of active carbon (5) in the plane bag (4).
