Problems solved by technology

This life support system relies on on-site staff for on-site operation and control, and cannot remotely monitor the operating status of the system, nor can it automatically shut down, exhaust or switch according to the gas supply situation
In addition, the pressure of the gas supplied by this system fluctuates greatly

Embodiment Construction

[0024] see figure 1 , which shows an overall schematic diagram of the breathing air supply system 100 according to an embodiment of the present invention. As shown in the figure, the respiratory air supply system 100 is overall arranged in a series-parallel combination, and all the equipment of the system are arranged along the main pipeline 1 . The main pipeline 1 has an input end 11 communicating with the outside atmosphere for inputting air and an output end 12 communicating with an air consumption unit (not shown) such as a positive pressure protective suit for outputting air. The main line 1 branches near the input 11 into a first branch line 1 a and a second branch line 1 b , which respectively have a first input 11 a and a second input 11 b , and merge into the main line 1 upstream of the gas switching device 4 . A first air intake device 2a and a first pretreatment device 3a are sequentially arranged on the first branch line 1a, and a second air intake device 2b and a...

Abstract

The invention provides a respiration air feed system (100). The respiration air feed system is provided with a main pipe (1), wherein the input end (11) of the main pipe (1) communicates with the outside air, and the output end (12) of the main pipe (1) communicates with an air using unit. The respiration air feed system comprises air inlet devices (2a and 2b), preprocessing apparatuses (3a and 3b), an air monitoring apparatus (4), a secondary air storage tank (5) and a temperature adjusting apparatus (6), wherein the air inlet devices (2a and 2b) are used for sucking in air from the outside world and compressing the air, the preprocessing apparatus (3a) comprises a drying device (31a) used for drying air, a primary air storage tank (32a) used for temporarily storing the air and a filtering device (33a) used for filtering out the unwanted ingredients in the air, the preprocessing apparatus (3b) comprises a drying device (31b) used for drying air, a primary air storage tank (32b) used for temporarily storing the air and a filtering device (33b) used for filtering out the unwanted ingredients in the air, the air monitoring apparatus (4) comprises a detecting device (41) and an analysis control device (42), the detecting device (41) is used for detecting the content or contents of one or more ingredients in the air, the analysis control device (42) is used for analyzing the detection results and giving out control signals according to the analysis result, the secondary air storage tank (5) is used for buffering the pressure of air, and the temperature adjusting apparatus (6) comprises a cooling device (61) used for cooling air and a heating device (62) used for heating air.

Description

technical field [0001] The present invention relates generally to protective equipment, and more particularly to a breathing air supply system. Background technique [0002] Some toxic and hazardous substances may be stored in biosafety laboratories, chemical laboratories and some medical places, and workers who conduct experiments and operations in these places need to wear protective equipment to keep them separated from these dangerous substances. For example, in a Biosafety Level 4 (BSL-4) laboratory, workers must wear airtight positive pressure suits and breathe through a ventilator connected to the inside of the suit. The gas supply device for the protective clothing or the ventilator can be a gas storage bottle carried by the staff or a centralized gas supply system. A centralized air supply system generally collects air from the outside atmosphere, performs a series of treatments on the collected air, and then delivers it to the protective clothing. Internationally...
