Abstract
The utility model relates to a filtering absorber, in particular to a filtering absorber with a humidity indicating device. The filtering absorber comprises a casing, an air inlet is formed at one end of the casing, an air inlet diffusion chamber is arranged between the casing and the air inlet, an air outlet is formed at the other end of the casing, a discharge diffusion chamber is arranged between the air outlet and the casing, an efficient filtering layer and an activated charcoal filtering layer are arranged in the casing in sequence in the air current direction, and the humidity indicating device is inserted at the upper part of the casing. The filtering absorber has the advantages of strong intuitiveness, convenient operation and prolonged service life.
Description
Technical field
The utility model is a kind of gas-particulate filter, particularly a kind of gas-particulate filter with moisture indicator means.
Background technology
Gas-particulate filter is important air processor in protection works and the military manned equipment in the prior art, its main effect is: filter the airborne toxic smoke of outside contamination, malicious mist, radioactive dust and gas, to guarantee fortification or the inner air that cleaning is provided of equipment for being attacked.Gas-particulate filter is made up of fine filter (high efficiency filter layer) and canister (activated carbon filter layer) two parts.High efficiency filter layer and activated carbon filter layer make moist, and the back is easy lost efficacy, and imported and exported the flange end cap so gas-particulate filter is forbidden to open at ordinary times, in order to avoid damp failure.But gas-particulate filter all might cause gas-particulate filter body seal performance to descend in arbitrary link existing problems such as production, transportation, installation, use, humid air enters gas-particulate filter inside, cause gas-particulate filter in depositing the time limit, to lose efficacy, influence result of use, threaten personnel's life security.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, a kind of gas-particulate filter with moisture indicator means is provided, so that in the gas-particulate filter use, can make things convenient for administrative staff to differentiate the relative humidity situation of gas-particulate filter inner air, prevent that gas-particulate filter lost efficacy because of humidity.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of gas-particulate filter with moisture indicator means, comprise housing, one end of housing is an air inlet, be provided with the air intake diffuser casing between described housing and air inlet, the other end of described housing is provided with air outlet, be provided with the discharging diffuser casing between described air outlet and housing, be provided with high efficiency filter layer and activated carbon filter layer successively along airflow direction in the described housing, the top of described housing is plugged with moisture indicator means.Moisture indicator means humidity inside inductive means contacts with the air of gas-particulate filter inside, and its color changes with the relative air humidity of gas-particulate filter inside.The color that administrative staff watch the humidity inductive parts by transparent windows, thus can judge the relative humidity situation of gas-particulate filter inside, prevent that gas-particulate filter lost efficacy because of humidity.
As preferably, described moisture indicator means comprises shell, humidity inductive parts and transparent windows, and transparent windows places the top of housing, and the humidity inductive parts are positioned at shell.
As preferably, the bottom of described shell is provided with air vent, and described air vent is connected with high efficiency filter layer and activated carbon filter layer in the housing.
As preferably, described humidity inductive parts are discolour silica gel.
As preferably, described humidity inductive parts are humidity indicating card.
Therefore, a kind of gas-particulate filter that the utility model provides with moisture indicator means, intuitive is strong, and is easy to operate, increases the service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of moisture indicator means in the utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
