Abstract
The invention relates to the technical field of fire-fighting and anti-gas appliances, in particular to a canister of a fire-fighting filter type self-rescue respirator. The canister comprises a canister body; the canister body is provided with an air inlet and an aspiration inlet; a filter agent layer and a drying layer are arranged in the canister body; and the drying layer is an activated carbon fiber layer. The canister adopts activated carbon fiber to replace lithium bromide dryer to be served as water vapor adsorbing material, can sufficiently guarantee the water vapor adsorption rate, can not produce potential safety hazard caused by the lithium bromide dryer, improves the filter effect, and reduces the weight.
Description
Technical field
The present invention relates to a kind of fire-fighting gas defence utensil technical field, is the parts that self-rescue apparatus is crossed in fire-fighting, relates in particular to a kind of canister of filtering respiratory protective devise for self-rescue from fire.
Background technology
During continuous increases fast-developing and fire frequency in recent years, the configuration of escape equipment is one of the factor that must consider in the city, and that filtering respiratory protective devise for self-rescue from fire disposes is the most extensive.But whether the structure-design technique of a product is scientific and reasonable, often is related to user's health and safety.The core component of filtering respiratory protective devise for self-rescue from fire is a canister; Canister is provided with filter toxicant layer and drying layer; In the prior art, drying layer all adopts the lithium bromide drier as the steam adsorbent, the drier that this lithium bromide is synthetic; Though it is better to absorption steam effect, can produce murder by poisoning to user's health.Put down in writing according to pertinent literature; Human body is obeyed into lithium bromide can suppress central nervous system, and long-term suction can cause the disorder of skin macula and nervous centralis.Therefore, there is certain potential safety hazard in the canister of prior art in the use of filtering respiratory protective devise for self-rescue from fire.
Summary of the invention
Technical problem to be solved by this invention is to overcome the prior art defective, and a kind of canister of filtering respiratory protective devise for self-rescue from fire is provided, and can fully guarantee the adsorption rate of steam, and is safe and reliable, and strengthened filter toxic effect fruit.
The technical scheme that technical problem adopted that the present invention solves is: a kind of canister of filtering respiratory protective devise for self-rescue from fire; Comprise tank body; Tank body is provided with air inlet and air entry, is provided with filter toxicant layer and drying layer in the tank body, it is characterized in that drying layer is the NACF layer.
NACF is to adopt natural or staple fibre to surmount the efficient sorbing material in granular activated carbon through what special process such as high temperature, catalysis were made, contains highly developed microcellular structure, and it is big to have specific area, therefore has very high wettability power.Substitute the lithium bromide drier as the steam sorbing material with NACF, human body is had no injury, and can fully guarantee the adsorption rate of steam, can not produce the potential safety hazard that the lithium bromide drier produces.NACF light weight in addition can reduce the weight of canister.
NACF also has characteristics such as the adsorption desorption capacity is high, adsorption desorption speed is fast, good purification, pernicious gases such as the airborne ozone of ability adsorption filtration, nitrogen dioxide and sulfur dioxide and stench, poison gas, flue gas.Therefore, on gas defence utensils such as anti-poison respirator also as the filter malicious material.NACF has functions/drying except substituting the lithium bromide drier in the present invention, can also strengthen its filter toxic effect fruit further as air is filtered poison, is to achieve many things at one stroke.
During practical implementation, above-mentioned NACF layer is the NACF felt.
During practical implementation; Also be provided with web plate, following web plate, filter paper and particulate filter in the tank body; Go up web plate, filter toxicant layer, NACF layer, following web plate and particulate filter from top to bottom successively, be respectively equipped with filter paper between last web plate and filter toxicant interlayer, filter toxicant layer and NACF interlayer and NACF interlayer and following web plate.
During practical implementation, tank body comprises upper tank body and lower tank, is provided with sealing ring between upper tank body and lower tank.
The invention has the beneficial effects as follows: the present invention substitutes the lithium bromide drier as the steam sorbing material with NACF; Can fully guarantee the adsorption rate of steam; Can not produce the potential safety hazard that the lithium bromide drier produces; And strengthened filter toxic effect fruit, alleviated weight, can be widely used in occasions such as hotel, office building, market, bank, specialized hospital and post and telecommunications, power department, place of public amusement.
Description of drawings
Below in conjunction with accompanying drawing and embodiment invention is further specified.
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure: 1, filter toxicant layer 2, NACF layer 3, last web plate 4, particulate filter 5, filter paper 6, upper tank body 7, lower tank 8, sealing ring 9, following web plate 61, air inlet 71, air entry.
The specific embodiment
Among Fig. 1; A kind of canister of filtering respiratory protective devise for self-rescue from fire; Comprise tank body, tank body comprises upper tank body 6 and lower tank 7, and 7 of upper tank body 6 and lower tanks are provided with sealing ring 8; Tank body is provided with air inlet 61 and air entry 62; Go up web plate 3, filter toxicant layer 1, NACF layer 2, following web plate 9 and particulate filter 4 in the tank body from top to bottom successively, last web plate 3 and 1 on filter toxicant layer, filter toxicant layer 1 and 2 on NACF layer and 2 on NACF layer and 9 of following web plates are respectively equipped with filter paper 5, and NACF layer 2 is the NACF felt.When concrete the use, the air inlet 61 of canister adopts the soft rubber sealing with air entry 62, and sealing keeps for a long time, and performance is constant before the deadline to guarantee product.The present invention utilizes filter toxicant, filter cigarette element and the NACF in the canister to realize the filtering respiratory protective devise for self-rescue from fire function; Toxic gases such as the airborne carbon monoxide in the scene of a fire, hydrocyanic acid, dense smoke, malicious mist are filtered out; Make it to become the comparatively air of cleaning, supply the survivor to breathe usefulness.The present invention substitutes the lithium bromide drier as the steam sorbing material with NACF, human body is had no injury, and can fully guarantee the adsorption rate of steam, can not produce the potential safety hazard that the lithium bromide drier produces.NACF light weight in addition can reduce the weight of canister.NACF has functions/drying except substituting the lithium bromide drier in the present invention in addition, can also strengthen its filter toxic effect fruit further as air is filtered poison.
