Description
Art
The utility model belongs to personal respiratory protection safety device, particularly a kind of oxygen breathing apparatus.
Background technology
At present, the oxygen breathing apparatus that domestic and international sizing is produced is when normally working: the temperature that personnel's suction gas is worn in (1), respirator is quite high, and the maximum temperature of the respirator of different model suction gas is under various operating conditions generally within the scope of 32 ~ 40 DEG C; (2), that the humidity of personnel's suction gas worn by respirator is quite high, and the humidity of the respirator of different model suction gas is under various operating conditions generally 100%.Therefore, there are the following problems: (1), due to the temperature and humidity of suction gas too high, define the continuous working period wearing this type of respirator work, generally should more than 4 hours; (2), due to the temperature and humidity of suction gas too high, be unfavorable for the realization of other functions of respirator; (3), due to the temperature and humidity of this type of respirator in use suction gas too high, so it is very uncomfortable that personnel's subjective sensation worn by respirator.
In a word, this type of respirator is not only dangerous but also uncomfortable also will by the restriction of service time and the realization being unfavorable for other functions of respirator.
Summary of the invention
The utility model belongs to personal respiratory protection safety device, particularly a kind of oxygen breathing apparatus.The utility model: 1, be provided with desiccant layer in the optional position of the closed circuit breath cycle passage of respirator.2, at CO
2desiccant layer is provided with in tourie.3, the absorbent in CO2 absorber layer is not by the absorbent that the drier in desiccant layer affects.
Technical solution of the present utility model can realize according to such as under type:
A kind of oxygen breathing apparatus, comprising: expiration flexible pipe, breathing bag or tidal air cabin, CO
2tourie, cooler, inhaling hose, breathing mask; Described breathing mask is connected with expiration flexible pipe, and described expiration flexible pipe is connected with breathing bag or tidal air cabin, described breathing bag or tidal air cabin and CO
2tourie is connected, described CO
2tourie is connected with cooler, and described cooler is connected with inhaling hose, and described breathing mask is connected with inhaling hose, forms the closed circuit breath cycle passage of respirator thus; Described CO
2containing CO in tourie
2absorber layer; It is characterized in that: in the optional position of closed circuit breath cycle passage, desiccant layer is set.
Further, at CO
2in tourie, desiccant layer is set.
Further, the absorbent in CO2 absorber layer is not by the absorbent that the drier in desiccant layer affects.
Further, cooling agent is contained in cooler.
The utility model oxygen breathing apparatus compares with existing oxygen breathing apparatus following features:
(1), owing to being provided with desiccant layer in the optional position of closed circuit breath cycle passage, have employed the cooler that cooling agent is housed, so, have significant cooling-down effect, the temperature of suction gas when respirator can be worked under various operating conditions controls from start to finish within the scope of 15 ~ 25 DEG C.
(2), owing to being provided with desiccant layer in the optional position of closed circuit breath cycle passage, have employed the cooler that cooling agent is housed, so, have significant effect on moisture extraction, the humidity of suction gas when respirator can be worked under various operating conditions controls from start to finish in 40 ~ 80% scopes.
(3), use this type of respirator not only safety but also comfortable also by service time restriction and also be conducive to the realization of other functions of respirator.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
The purpose of this utility model is realized by following technical measures:
Temperature in order to suction gas when being worked under various operating conditions by respirator 10 controls from start to finish within the scope of 15 ~ 25 DEG C, humidity controls from start to finish in 40 ~ 80% scopes
(A), have employed the structure that desiccant layer 5 is set in the optional position of closed circuit breath cycle passage.
(B), have employed cooler 6 structure that cooling agent 7 is housed.
(C), have employed the CO2 absorbent do not affected by drier.
As shown in Figure 1, to enter through expiration flexible pipe 1, breathing bag or tidal air cabin 2 when people wears the gas of breathing out through breathing mask 9 when the utility model respirator 10 works CO is housed
2the CO of absorber layer 4, desiccant layer 5
2tourie 3.CO
2cO in tourie 3
2absorber layer 4 is by the CO in breath
2remove, CO
2desiccant layer 5 in tourie 3 is by the moisture removal in breath and keep the certain relative humidity in breath.Purify through CO2 absorber layer 4 and desiccant layer 5, gas after moisture absorption regenerates after mixing with the pure oxygen of input.Through CO
2the gas that tourie 3 exports enters cooler 6, from cooler 6 exports after carrying out heat exchange with cooling agent 7.The gas exported from cooler 6 sucks human lung through inhaling hose 8, breathing mask 9.The temperature of suction gas remains within the scope of 15 ~ 25 DEG C from start to finish, humidity remains in 40 ~ 80% scopes from start to finish, that is guarantee that people wears the temperature of suction gas when the utility model respirator 10 works under various operating conditions and remains within the scope of 15 ~ 25 DEG C from start to finish, humidity controls from start to finish in 40 ~ 80% scopes.
In another kind of embodiment, desiccant layer 5 can be arranged on the optional position of closed circuit breath cycle passage, e.g., and CO
2cO in tourie 3
2passage before absorber layer 4, CO
2the passage etc. of the passage between tourie 3 and cooler 6, cooler 6.
