Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] see figure 1 , the multi-stage air filter 1, CO filter 2, pressure reducer 3, aerosol humidifier 4 and vortex tube 5 are connected in series in sequence, the multi-stage air filter 1 is connected to the compressed air supply source, and the vortex tube 5 passes through The conduits are connected with a plurality of flow regulating valves 6 and a plurality of breathing masks 7 .

[0017] The multi-stage air filter 1 includes but not limited to a three-stage air filter.

[0018] The aerosol humidifier 4 for controlling air humidity has a flow regulating function, and can adjust the humidity according to actual needs.

[0019] The vortex tube 5 used to control the air temperature has a flow regulating function, and can adjust the temperature as required.

[0020] The breathing mask 7 is a breathing mask with one-way breathing function, that is, when the breathing mas...

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 [0001] The invention relates to a respirator, in particular to a respirator protective device used in coal mines, non-ferrous metal mines and other environments with toxic and harmful gases and dust. Background technique [0002] Positive pressure respirator is a kind of respiratory protective equipment widely used in dense smoke, toxic and harmful gas, dust and hypoxic environment. At present, the commonly used structures of positive pressure respirators are the air source part and the breathing mask. The air source part adopts the way of high-pressure gas cylinder supply, which has the disadvantages of high pressure, large volume, short gas supply time, etc., and is not suitable for long-term uninterrupted use. Respiratory protection. In coal mines, non-ferrous metal mines and other environments with ventilation equipment, the on-site compressed air supply can be directly used. After filtration and decompression, it can be directly used for the air supply ...
