The present invention relates to a high-vacuum serial condenser system that can minimize a pressure drop of fluid in condensers by disposing straight pipes between the condensers and installing baffles at predetermined angles in the condensers.

The heat exchange system is for heating water from a water source and comprises first and second flooded heat exchangers that have steam sides that are each independently fed with steam, but water sides that are serially fed with water through the first heat exchanger then through the second heat exchanger. The system also comprises first and second control valves located at or downstream of subcooled condensate outlets of the first and second heat exchangers, first and second water temperature sensors at or downstream of the heated water outlets of the first and second heat exchangers, and a control device for receiving temperature data from the first and second water temperature sensors and for controlling the first and second control valves. The proportions of the first and second steam sides that are flooded are respectively selectively adjusted by controlling the debit of condensate allowed through the first and second subcooled condensate outlets with the first and second control valves, for allowing heat exchange to the water to be adjusted as a result of the water temperature measured by the first and second water temperature sensors. The first and second control valves are set in one of a first state in which they are both at least partly opened to allow effective heat exchange from the steam to the water in both first and second heat exchangers, and a second state in which one of them is closed while the other is at least partly opened to have an effective heat exchange from the steam to the water in only one of the first or second heat exchangers while the first and second steam sides remain both supplied with steam.

A condensation dedust-demister device, comprises at least one of the followings: a condensator, a refluent demister, a large curve demister, a mixed curve demister and a super-sine demister etc.. Said condensator with a shell/cavity style pipeline refrigerating system or cooling system can condense dust into mist/haze and be designed as the first class tube demister, consequently said refluent demister and so on can collect and dedust-demist what condensator condensed by centrifugal effect, with the assisting of easiness made by collecting liquid wall and drain as well as multiple classes composition the condensation dedust-demister set can dedust flue gas to 0 mg/Nm3 and demist to 10 mg/Nm3 when raw gas containing dust less than 20 mg/Nm3. This set can remove grains of SO3 aerosol and Hg0 etc. due to be condensed to haze at the same time.

A liquid separator and concentrator is disclosed. An example liquid separator and concentrator includes a separator column. A spray chamber has a sprayer nozzle to spray an influent within the spray chamber and create a falling film in the separator column. A heating jacket surrounds the separator column, wherein the heating jacket heats the falling film to evaporate at least one portion of the falling film and leaves a concentrate. A concentrate collection vessel receives the concentrate from the separator column.

The present invention relates to a precision air conditioner with an indirect evaporative unit, which comprises a gas-gas heat exchanger, an external circulation fan, an internal circulation fan, a gas filter module, a gas humidification module, an evaporator, a condenser, a condenser fan, a compressor and an air conditioner enclosure. The combination of indirect evaporative cooling and mechanical refrigeration enables indirect evaporative cooling to operate all year round with high air conditioning and refrigeration efficiency. During summer, mechanical refrigeration is used for secondary cooling to achieve the desired temperature. Further, the condenser of the precision air conditioner is upgraded to an indirect evaporative condenser, and the mechanical refrigeration efficiency can be greatly improved.

Large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.
