摘要

在大型直接空冷机组(直冷机组)中

由于北方地区冬夏季及昼夜温差Δt很大

导致空气凝汽器(空凝器)中应抽出的气汽混合物容积流量相差很大

如果抽真空系统不能及时将气汽混合物抽出

会大大降低空凝器的换热效果。对此

提出当环境温度在2℃以上时

可选用Δt=5℃来优化水环式真空泵(水环泵)运行;当环境温度在2℃以下时

可选用Δt=3℃来优化水环泵运行。此外

夏季空凝器运行压力较高

需时刻监视水环泵的循环冷却水温度

防止水环泵工作水汽化

影响空凝器换热性能。

Abstract

Because of large temperature difference between summer and winter

as well as in day and night

in north China

the volume flow rate of air-steam mixture

that should be extracted out from the air-cooled condenser

is variating considerably.If the said mixture isn't drawn out by the vacuum-extracting system

the effect of heat transfer in air-cooled condenser will decrease sharply.For this

a reasonable scheme has been put forward as follows:in the case of ambient temperature being above 2 ℃

the operation of water-ring pump can be optimized by using Δt=5 ℃;in the event of ambient temperature being below 2 ℃

the operation of water-ring pump can be optimized by using Δt=3 ℃.Furthermore

the pressure in air-cooled condenser during operation in summer is comparatively higher

the temperature of circulatory cooling water for the water-ring pump has to be always monitored

preventing the working water in said pump from vapourization

so as not to affect the effectiveness of heat transfer in the air-cooled condenser.
