Description

一种用于洁净新风系统的负压脱附型除湿去毒工艺
技术领域
本发明属于洁净新风处理的技术领域,具体涉及一种用于洁净新风系统的负压脱附型除湿去毒工艺。特别是涉及一种应用于洁净新风系统,利用吸附剂变压过程中对水蒸气、二氧化碳、二氧化硫、硫化氢、二氧化氮等有毒有害气体吸附量的变化,实现对新风除湿去毒处理。
背景技术
医院手术室、ICU病房、生物实验室、洁净厂房等公共建筑、工业建筑的室内都需要提供连续的洁净新风,在制取洁净新风的工艺流程中,需要对含湿量进行控制、对有毒有害气体进行清除。
在气候潮湿地区,控制新风的含湿量需要进行除湿处理。目前,进行除湿处理的方式主要有三种:冷凝除湿、溶液除湿、转轮除湿。
溶液除湿与转轮除湿因设备尺寸较大、占用建筑空间较多、设备投资费用及运行费用较高等原因,应用于洁净新风处理系统受限较多。目前,洁净新风系统主要采用外接冷源的冷凝除湿方式。
外接冷源的冷凝除湿:利用低温冷媒(冷冻水、制冷剂等)通过表冷器盘管,降低与之接触的湿空气温度,使之达到饱和状态(露点温度)后,空气中的水蒸汽凝结析出而进行除湿的方式。经表冷器冷却处理后,所处理空气的温度、含湿量均降低,达到饱和状态(露点温度),此时新风温度一般在13℃以下。通常,为满足建筑物室内温度控制参数要求(一般为20-26℃),冷凝除湿后需做再热处理。
外接冷源的冷凝除湿方式,存在如下问题:新风除湿后温度远低于室内设定温度,过低的新风温度意味着消耗庞大的能量(一般为电能)来制取低温度的新风(13℃),而这些冷量仅有少部分被用来冷凝新风中的水蒸汽,并且在洁净新风减焓除湿处理后,新风送风温度偏低,存在着管路及风口容易结露等弊端,此时需要对洁净新风再热,再热过程又需要巨量的能源(电能或热能)为洁净新风提供热量。由于除湿处理过程中出现了液态水,在风道局部形成潮湿环境,容易滋生各种病菌,降低了空气质量和卫生状况。
随着经济的不断发展,以及全球工业化程度越来越来高,给大气造成了严重的污染,室外空气中的二氧化碳(CO2)、一氧化氮(NO)、二氧化氮(NO2)、硫化氢(H2S)、二氧化硫(SO2) 等有毒有害气体大量增加;目前洁净室新风系统去毒普遍的做法为采用活性炭过滤,这样的去毒技术路线存在一定的缺陷:一是容尘量较小,需要经常更换活性炭,并且由于难以判断活性炭的污染程度,增大了活性炭的用量,增加了维护人员的工作量;二是过滤阻力大,洁净新风系统运行能耗比较高。
发明内容
本发明的目的在于避免现有技术中的不足而提供一种用于洁净新风系统的负压脱附型除湿去毒工艺,其采用一种新的工艺方法,采用可吸附水蒸汽和有毒有害气体的吸附剂,在常压工况下吸附新风中的水蒸汽和有毒有害气体,在负压工况下解吸脱附水蒸汽和有毒有害气体并排出室外,从而实现洁净新风处理过程的除湿去毒功能,保持洁净新风系统在干工况下运行,保证了系统卫生效果,并节能运行、投资费用和运行费用大幅降低。
为解决上述问题,本发明提供一种用于洁净新风系统的负压脱附型除湿去毒工艺,包括以下步骤:
S1:新风自室外引入空气处理机的壳体;
S2:新风流经装有吸附剂的箱笼,新风被除湿去毒;
S3:装有吸附剂的箱笼离开新风流道,并靠近负压脱附罐;
S4:箱笼中的吸附剂卸入负压脱附罐中;
S5:关闭负压脱附罐的密封阀,真空泵对脱附罐抽真空,对吸附剂进行负压脱附;
S6:真空泵停转,开启密封阀,吸附剂被送返箱笼;
S7:箱笼返回风道中;继续对新风除湿去毒;
S8:新风除湿去毒后的新风流出壳体,进行后续其它处理;
作为优选,可以把S2-S6的步骤分成两个并行的相同进程,交替轮换进行,即其中一项进程处于S2步骤时,另一项进程处于S3-S6进程。如此可以保证有一个进程处于对新风处于除湿去毒状态,实现对新风的连续除湿去毒。
作为优选,除湿去毒箱笼吸附时的压力为0.9~1.1个大气压(常压),负压脱附罐解吸脱附时的压力为0.2~0.6个大气压(负压)。
作为优选,吸附剂被包裹在带网孔的金属材料制成的球形空腔内,球形空腔的直径为 15mm~40mm,每组除湿去毒单元配套数百个装满吸附剂的网孔球。
作为优选,吸附剂是3A分子筛和13X分子筛的混合物,这两种物质的体积混合比为1:1。
