Description

Respiratory protection article adapter with timing function
Technical Field
The invention relates to the technical field of breathing protective masks, in particular to a breathing protective article adapter with a timing function.
Background
The respiratory protection mask is a special labor protection article for protecting the respiratory system of people, is the last line of defense against dust and toxic substances in the environment, and generally consists of a filter element and a mask main body. The mask main body is tightly attached to the face of a user to isolate air and play a role in sealing; the filter element mainly comprises a poison filtering box or a poison filtering tank, plays a role in filtering toxic gas and dust, and is widely applied to the fields of petroleum, chemical engineering, mines, metallurgy, military affairs, fire fighting, emergency rescue and relief, health and epidemic prevention, science and technology environmental protection and the like.
The past field survey of occupational health finds that the replacement period of respiratory protection articles by enterprises often lacks scientific basis, and respiratory protection articles of similar enterprises are often carried or used along with the distribution management system. However, even if the production processes of different enterprises are the same, the raw materials, working system and protection facilities used are not always consistent. Thus, it is extremely erroneous and dangerous to schedule the respiratory protection article change cycle at will. (see quantitative analysis of respiratory protection article selection in certain can plants [ J ] China occupational medicine, 2017,44(02): 221-.
Enterprises at present do not have quantitative indexes and replacement bases, so that the replacement period of the breathing protective articles is set at will, and the management mode can bring adverse effects on two aspects:
(1) the overlong replacement period exceeds the adsorption capacity of the canister or the canister, so that dust and toxic substances penetrate through the canister or the canister, workers are exposed in an overproof working environment, and the respiratory protection article does not play a corresponding protection role.
(2) The short replacement period causes the replacement of the protective articles too frequently, and the canister or canister with the surplus adsorption capacity is replaced, thereby causing unnecessary waste.
Under actual working conditions, the poison filtering box is used for a long time under a more dangerous condition, the protection capability of the poison filtering box cannot meet the protection requirement of a workplace, health risk potential hazards are brought to workers, and operation management potential hazards are brought to enterprises.
Through consulting documents, the correlation between the penetration time of the poison filtering box and the use environment is extremely high, and the method for determining the penetration time through measuring the penetration concentration after filtering materials has two difficulties in the aspect of specific industrial application; secondly, in actual work, along with the change of labor intensity, the water vapor in breath has nonlinear influence on the adsorption capacity of the filter material, and the error difficulty of the part is higher.
The existing mature calculation model for evaluating the service life of the filter material is a 3M company which synthesizes the information of the type and concentration of the on-site poison, the on-site temperature and humidity parameters and the like, estimates and calculates the adsorption time of the filter material and provides a proposal with a targeted replacement period for replacing a poison filtering box and a poison filtering tank. Therefore, the statistics of the actual use duration of the filter material is particularly important.
