立式大型冷凝塔是制药、冷库、化工和机电等行业进行空调、制冷和干燥工艺中的必备设备之一。由于这些冷凝塔 (实用中多为塔群 )多安装于室外 ,利用水柱落差与空气进行自然热交换降低水温。冷凝塔水柱落入集水池时溅落激发的噪声一般可达 90dB(A)左右的声级。成为影响周围环境的污染源。本文介绍的内外集水圈与锥体散热器组成复合的降噪器件不仅可使冷凝塔的落水噪声降低 8～ 9dB(A) ,而且可使冷凝塔落水的热交换率增强 ,收到一举两得的结果。
Vertical large condensing tower is the pharmaceutical, cold storage, chemical and mechanical and electrical industries for air conditioning, refrigeration and drying technology in one of the necessary equipment. Since these condensing towers (mostly utility tower groups) are mostly installed outdoors, the water temperature drops due to the natural heat exchange between the water column drop and the air. Condensation tower water column falling into the pool splash excitation noise up to about 90dB (A) about the sound level. Become a source of pollution affect the surrounding environment. This paper describes the composition of the inner and outer collector ring and the cone radiator composite noise reduction device can not only reduce the condensing tower falling water noise 8 ~ 9dB (A), but also condensate tower falling water heat exchange rate, receive double benefit result.
