The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

An automated flush system for an evaporative cooling system may be employed in barns or other facilities that house animals to provide cooling and to reduce production loss. The evaporative cooling control system may include an automated flush system that has a controllable valve at a flush end of the cooling system. Based on a timer, the controllable valve is opened and water drains (e.g., pumped or gravity feed) out of the cooling pad enclosure. Fresh water is introduced at the “fill” end of the system, rinsing out the evaporative cooling pads. After a predetermined time, the valve at the flush end of the system is closed, and the fresh water refills the cooling pad enclosure.

An electrostatic precipitating apparatus for a cooling tower is provided. The precipitating apparatus include an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied and a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded, a washing water supply spraying the washing water to the electrostatic precipitator, and a frame assembly supporting the electrostatic precipitator. The electrostatic precipitator includes a first setting beam having a plurality of lower slots into which the discharge electrodes are fixedly inserted, and the frame assembly includes a lower frame extending in a stacking direction of the discharge electrodes to support the first setting beam, via which a voltage is applied to the discharge electrode.

The invention also relates to a system (200) comprising an evaporative humidifier and cooler apparatus (1) for humidification and cooling of air, a control device (100) and a sensor device (10) arranged in communication with the control device (100).

A liquid collection assembly positionable between a fill material and a fan of a cooling tower for collecting liquid gravitating through the fill material while allowing air to pass up to the fill material. The liquid collection assembly includes a plurality of trough assemblies supported in a spaced apart, vertically overlapping relationship to provide a uniform path for rising air, to capture the down flowing liquid, to provide a barrier between the liquid distribution system and the fan, and to carry the liquid into the at least one gutter. The trough assemblies are supported by a first end plate and a second end plate through which trough assemblies extend.

An air-over evaporative heat exchanger with multi-lobed or “peanut” shaped tubes replacing conventional round or elliptical tubes. The tubes have a narrow horizontal cross section and tall vertical cross section to allow the multiplication of surface area in the same coil volume while maintaining or increasing the open-air passage area. This configuration allows the coil to have an overall external heat transfer coefficient much higher than a conventional coil, while the tube shape allows the use of thinner material, reducing the weight and cost of the heat exchanger.

The present invention relates to an evaporator of a working fluid for an OTEC plant, comprising an elongated evaporator body extending along a main axis, a bundle of evaporators transporting hot water and extending along the main axis, and a sprinkling system extending above the bundle of evaporators and suitable for sprinkling the working fluid in the liquid state onto the bundle of evaporators in order to evaporate this working fluid.

The evaporator body defines a bottom and an exhaust space for the gaseous working fluid between the bottom and the bundle of evaporators. The evaporator further comprises a damper system arranged in the exhaust space and configured to damp the drop of working fluid droplets in a non-evaporated liquid state after passing through the bundle of evaporators.

The present invention relates to a working fluid evaporator for an OTEC plant, comprising an evaporator body extending along a longitudinal axis, a bundle of evaporators transporting hot water and comprising a plurality of evaporation elements, a sprinkling system extending above the bundle of evaporators and a casing covering the bundle of evaporators and the sprinkling system, an evacuation area being formed between end columns of the evaporator elements and the casing. The evaporator further comprises a redistribution system configured to collect the working fluid in a liquid state in the evacuation area and direct it to interior evaporator elements.

An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel. The wet channel is located directly above the dry channel. A first side of the dry channel is connected to a first opening with a fan and outside air.

Disclosed are a cooling water-saving device for a cooling tower, and a wet cooling tower. The cooling water-saving device comprises indirect heat exchange devices and a water collecting tank. The inner wall of a cooling tower shell is sealed by the water collecting tank. The indirect heat exchange device comprises a heat exchange channel and a heat insulation channel. The heat insulation channel penetrates through the bottom of the water collecting tank, and the bottom inlet of the heat insulation channel communicates with air entering from the bottom of the cooling tower shell. The heat exchange channel for shielding water drops is arranged at the top outlet of the heat insulation channel, and the top of the heat exchange channel extends into an air outlet in the upper part of the cooling tower shell. The lower outlet of the heat exchange channel communicates with a rain area.
