Abstract
The invention discloses a positive pressure respirator. A multi-stage air filter (1), a CD filter (2), a pressure reducer (3), a mist humidifier (4) and a vortex tube (5) are sequentially connected in series, the multi-stage air filter (1) is connected with a compressed-air supply source, and the vortex tube (5) is connected with at least one flow adjusting valve (6) and at least one breathing mask (7) through ducts. The positive pressure respirator is simple in structure, the external compressed-air supply source is connected with the positive pressure respirator so that the air source can be guaranteed to continuously supply compressed air for a long time, the positive pressure respirator has a purification function, a heating function and a humidification function, and external air can be guaranteed not to be inhaled by the human body through the breathing mask which has a one-way breathing function.
Description
Technical field
The present invention relates to a kind of respirator, relate in particular to a kind of respiratory protection utensil under the environment such as toxic and harmful, dust that has for colliery, nonferrous metal mine etc.
Background technology
Positive pressure respirator be a kind of under dense smoke, toxic and harmful, dust, anaerobic environment widely used a kind of respiratory protection utensil.The structure that positive pressure respirator is commonly used at present is source of the gas part and breathing mask, and source of the gas partly adopts the mode of gas cylinder air feed, has the shortcomings such as pressure is large, volume is large, service life is short, is not suitable for long-time continual respiratory protection.And in colliery, nonferrous metal mine etc. itself possesses the environment of ventilation equipment, can directly utilize the on-the-spot wind air feed source of the gas of pressing, in the source of the gas supply that is directly used in respirator after the processing such as filtration, decompression, needn't carry the gas cylinder air feed.
Summary of the invention
Problem solved by the invention is to provide a kind of positive pressure respirator that can directly utilize on-the-spot existing pressure wind air feed source of the gas to breathe.
In order to solve the problems of the technologies described above, positive pressure respirator provided by the invention, comprise breathing mask, multistage air cleaner, CO filter, pressure reducer, aerosol humidifier and vortex tube are connected in series successively, described multistage air cleaner connects presses wind air feed source of the gas, and described vortex tube connects at least one flow control valve and at least one described breathing mask by conduit.
As a modification of the present invention, described multistage air cleaner includes, but are not limited to three grades of air cleaners.
Preferably, be used to the described aerosol humidifier of controlling air humidity, possess flow regulating function, can regulate according to actual needs the humidity size.
Preferably, be used to the described vortex tube of controlling air themperature, possess flow regulating function, can regulate as required temperature level.
Preferably, described breathing mask is the breathing mask with unidirectional respiratory function, and namely when correctly wearing the use breathing mask, human body can only suck gas from the air supply pipe of breathing mask, and can not suck from the external world gas; The waste gas of characteristics of contaminated respiratory droplets can be discharged by the exhaust outlet of breathing mask.
Adopt the positive pressure respirator of technique scheme, adopt the external on-the-spot wind air feed source of the gas mode of pressing, multistage air cleaner, CO filter, pressure reducer, aerosol humidifier, vortex tube are connected in series, multistage air cleaner connects presses wind air feed source of the gas, and vortex tube is by conduit connection traffic control valve and breathing mask.
The invention has the beneficial effects as follows:
Adopt the external on-the-spot plenum system of wind air feed source of the gas of pressing can guarantee long-time continual source of the gas supply; The function that the mode that adopts multistage air cleaner, CO filter, pressure reducer, aerosol humidifier, vortex tube to be connected in series can reach low pressure air feed, air filtration, toxic gas removal, gas humidification, heat; Breathing mask with unidirectional breathing can guarantee that the ambient atmos environment is not sucked by human body.
In sum, the present invention a kind ofly can directly utilize on-the-spot existing pressure wind air feed source of the gas, possesses air filtration, toxic gas removal, humidification, heats, the positive pressure respirator of unidirectional respiratory function.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Wherein: 1, multistage air cleaner; 2, CO filter; 3, pressure reducer; 4, aerosol humidifier; 5, vortex tube; 6, flow control valve; 7, breathing mask.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1, multistage air cleaner 1, CO filter 2, pressure reducer 3, aerosol humidifier 4 and vortex tube 5 are connected in series successively, and multistage air cleaner 1 connects presses wind air feed source of the gas, and vortex tube 5 connects a plurality of flow control valves 6 and a plurality of breathing mask 7 by conduit.
Multistage air cleaner 1 includes, but are not limited to three grades of air cleaners.
For the aerosol humidifier 4 of controlling air humidity, possess flow regulating function, can regulate according to actual needs the humidity size.
For the vortex tube 5 of controlling air themperature, possess flow regulating function, can regulate as required temperature level.
Breathing mask 7 is for having the breathing mask of unidirectional respiratory function, and namely when correctly wearing the use breathing mask, human body can only suck gas from the air supply pipe of breathing mask, and can not suck from the external world gas; The waste gas of characteristics of contaminated respiratory droplets can be discharged by the exhaust outlet of breathing mask.
Referring to Fig. 1, adopt the external on-the-spot plenum system of wind air feed source of the gas of pressing can guarantee long-time continual source of the gas supply; The function that the mode that adopts multistage air cleaner, CO filter, pressure reducer, aerosol humidifier, vortex tube to be connected in series can reach low pressure air feed, air filtration, toxic gas removal, gas humidification, heat; Breathing mask with unidirectional breathing can guarantee that the ambient atmos environment is not sucked by human body.
