The process characteristics include a new control method,which eliminated the on-off-on water spraying;the spraying width varied with the slab width;the number of the cooling zone and loop,and the length of the narrow spraying zone increased;almost all the zone used air-water cooling spray nozzles,etc.

Based on experimental apparatus, how the spray density and water temperature affected the heat and mass transfer performance of the evaporative condenser are studied.

The effects of the spray density and the head-on air velocity on the heat transfer performance of the water film were investigated under various operation conditions.

Processing the Zinc alloy white smoke includes the gaseous and granular pollutant simultaneously with the packed tower,investigating the influence degree of pH as well as spray density of absorption fluid to the processing of Zinc alloy white smoke,and inspecting the effect of alkali-acid two stages treatment.

With a tester designed to study the spraying intensity,a systematic study was performed of the spraying in tensity of the swirling atomizing spraying nozzles under different conditions.

Relationships of pressure drop across the packing zone with the apparent velocity and flooding volocity with spraying density are obtained.

It is found that the main factor affecting padding + baffle plate pressure drop is gas velocity without spraying;When spraying,it is shown that gas velocity and spraying density jointly affect pressure drop.

Some parameters such as volume flux, nozzle width, outlet velocity, the height between nozzle and plate, and single nozzle hold-up water velocity were studied.

The flow field of nozzle outlet is simulated by using FDM,and the influence of nozzle width B on its flow field is investigated.

The distribution of spray droplet size,distribution of radial spray flux,and the uniformity of circumferential spray were studied.
