摘要
目的液态氧经汽化器转变为气态氧的过程中会大量吸收热量,为避免汽化器表面结冰现象对液态氧汽化速率的不利影响,特研制一种智能型喷淋除冰装置。方法采用灵活、轻便、耐用的PPR管道为主要材质,配以可灵活调节角度的喷淋头(顶部、中部、下部)、开关,结合汽化器的表面结冰分布情况及除冰需求进行设计,制作一种智能型汽化器专用喷淋装置。结果中部喷淋头的工作压力为3~4 kg,可根据需求调节出水量及出水方式;使用该液氧汽化器喷淋装置节省了人力、时间,夏天人工除冰时间约为30 min;冬天环境温度低,人工完全除掉冰时间约为2 h。结论此喷淋装置安装简单,使用灵活方便,材质坚固耐用,能够自动感应并启动与关闭并及时去除霜冻,避免表面结冰,还促使液氧汽化充分,为医院医用氧气的正常使用提供了更好的保障。
Objective A large amount of heat would be absorbed in the process of liquid oxygen being transformed into gaseous oxygen by vaporizer.In order to avoid the adverse effect of the vaporizer surface icing on the vaporization rate of liquid oxygen,a spray deicing device was developed.Methods Flexible,Light and Durable PPR pipes were used as the main materials,with spray heads(top,middle,lower)and switches which can adjust the angle flexibly.The design was combined with the distribution of ice on the surface of carburetor and the demand of deicing.An intelligent special spray device for carburetor was produced.Results The working pressure of the middle spray head was 3~4 kg,which can adjust the water output and the way of water outlet according to the demand.Using the spray device of the liquid oxygen carburetor saved manpower and time,and the artificial deicing time was about 30 min in summer.In winter,the ambient temperature was low,so it took about 2 h to completely remove the ice manually.Conclusion The spray device is simple to install,flexible to use,solid and durable in material,can remove frost in time,avoid surface icing,cause unnecessary load of vaporizer,make liquid oxygen vaporize fully,and provide better guarantee for normal use of hospital medical oxygen.
