近几年,随着大型空分设备液体输送业务的发展,对小型制氧机用户带来了生存的严峻考验,是停机购买贮槽(罐)满足用氧需求,还是降低成本、向节能要效益谋求发展呢?同时,也给小型制氧机制造厂商带来了挑战。事实上,气体分离设备行业在20世纪90年代就研制生产了全低压流程小型制氧机,其后十几年中,行业一直在跟踪研究这一技术,尤以近几年发展最快,已研制成功80、150、170(180)、300、350、600、800m~3/h等级规模的节能型制氧机,满足了用户的需要,使单位氧电耗下降了0.6度左右。根据气体分离设备行业统计资料,2000、2001、2002及2003年上半年行业生产小型空分设备的套数分别为52、50、78、30,呈上升趋势。目前,小空分有一定的市场。为此,本刊请小空分专家、苏州制氧机有限责任公司吴其蒙总师谈了节能型小型制氧机的情况,供广大用户选择时参考。
In recent years, with the development of the liquid transportation business of large-scale air separation plant, the user of small oxygen generator has brought a severe test of survival, whether to stop the purchase of storage tank (tank) to meet the oxygen demand or reduce the cost, The pursuit of efficiency? At the same time, it also poses a challenge for small oxygen manufacturers. In fact, in the 1990s, the gas separation equipment industry developed and manufactured a full-pressure oxygen plant with low-pressure process. In the following ten years, the industry has been tracking the technology, especially the fastest-growing in recent years. The success of energy-saving oxygen generator of 80,150,170 (180), 300,350,600,800m ~ 3 / h scale meets the needs of users and reduces unit oxygen consumption by about 0.6 degrees. According to the statistics of gas separation equipment industry, the numbers of small-sized air separation plants in production in the first half of 2000, 2001, and the first half of 2003 were 52, 50, 78 and 30, respectively, showing an upward trend. At present, a small space has a certain market. To this end, the publication of a small space experts, Suzhou oxygen limited liability company Wu Qimeng, general manager talked about energy-saving small oxygen machine for the general user selection reference.
