In the known technology, the existing industrial circulating water cooling tower is mainly composed of a fan duct, a fan installed on the top of the main body of the frame cooling tower, a water distribution system, a sump, a countercurrent water collector, and a countercurrent packing. It sends hot water from the heat exchanger of the process device, enters the water distribution system of the cooling tower, and sprays it into the packing system with a large specific surface area through the water distribution pipe of the water distribution system to the nozzle to form a water film; at the same time, the fan on the top of the cooling tower rotates Air extraction creates negative pressure inside the cooling tower, and dry and cold air outside the cooling tower continuously enters the tower; hot water and dry and cold air flow reversely or laterally on the surface of the filler, and the air takes away water molecules from the surface of the water film to generate evaporation and heat dissipation to achieve mass transfer The physical process of heat transfer; the increase of air enthalpy and humidity becomes hot and humid air, which is discharged to the atmosphere through the air duct; at the same time, the enthalpy and temperature of water decrease, and it falls into the water collection tank under the tower, and is pumped to the process heat exchange equipment for recirculation. When the hot and humid air discharged from the tower is mixed with the cold outside air, and when the moisture content of the mixed air reaches a supersaturated state, a large amount of visible water mist clusters are generated, which provides conditions for the production of haze, especially the whole process of circulating water cooling Water resources are consumed, resulting in waste of water resources; in order to eliminate fog, wet and dry cooling towers have also been developed in recent years, and two parallel channels with finned tubes are added on both sides of the upper part of the cooling tower. The dry and cold outside air passes through two parallel passages, passes through the dry section and the wet section in parallel, and mixes in the air chamber, and then discharges the atmosphere outside the tower with a relatively low humidity, but limited by its structure, one is the overall structure Clumsy, metal finned tubes have heavy weight, heavy load, high cost, and large equipment investment; second, the gap between the finned tubes and fins is easily blocked by dust and flocs in the air, and the metal finned tubes have poor corrosion resistance.

In the air-cooled wet-cooled combined water-saving and fog-eliminating cooling tower, the open-type circulating water-gas-liquid orthogonal membrane plate air cooler is composed of several open-type circulating water-gas-liquid orthogonal wave-shaped membrane plates arranged and combined into a water cooling section. The air channels in the channel and the air cooling section have different fluid flow directions and a dual-channel air cooler that is not connected to each other. Several open-type circulating water-gas-liquid orthogonal wave-shaped membranes form the windward and water-facing surfaces of the air channel and the water channel. The water membrane panel is made with a closed edge that completely isolates the air channel and the water channel, and several connection limit fulcrums and connections are installed on the open-type circulating water-gas-liquid orthogonal wavy membrane panel to position the membrane panel at intervals. location point.

In the above-mentioned open circulating water-gas-liquid orthogonal membrane plate type air cooler, the body of the open-type circulating water-gas-liquid orthogonal wave-shaped membrane plate is provided with reinforcing rib plates, several strip-shaped reinforcing ribs, and mesh reinforcing ribs. any kind of reinforcement.

In the air-cooled wet-cooled combined water-saving and fog-eliminating cooling tower, the open-type circulating water-gas-liquid orthogonal membrane plate air cooler installed on the main frame of the cooling tower and the corresponding matching primary water distribution spray system and adjustable shutters It is any kind of connection structure that is installed and connected inside and outside the side body of the main frame of the cooling tower, and the inside and outside are staggered and stacked.

In the air-cooled wet-cooled combined water-saving and fog-eliminating cooling tower, the open-type circulating water-gas-liquid orthogonal membrane plate air cooler installed on the main frame of the cooling tower is connected with the counter-current packing, the secondary water distribution system and the counter-current water eliminator. Installed with isolation baffle.

In the above-mentioned open-type circulating water-gas-liquid orthogonal membrane-plate air cooler, the outside of the frame of the main body of the cooling tower is located at the top of the inner tower connected to the open-type circulating water-gas-liquid orthogonal membrane-plate air cooler, and auxiliary air ducts and Auxiliary blower and isolation of the mixed air chamber in the cross-flow and counter-flow sections.

For the above-mentioned open circulating water-gas-liquid orthogonal diaphragm air cooler, the several air coolers installed on the main body of the cooling tower are open circulating water-gas-liquid orthogonal diaphragm air coolers and cross-flow air-cooled packing block air coolers. It is arranged on the frame of the tower body, and a cross-flow water eliminator is installed on the frame of the cooling tower body located inside the open-type circulating water gas-liquid orthogonal membrane plate air cooler and the cross-flow air-cooled packing block air cooler.

When the air-cooled wet-cooled combined water-saving and fog-eliminating cooling tower of the present invention is used, it is installed and connected to the set position according to the design requirements. When working, the water sprayed by the primary water distribution spray system enters the open-type circulating water-air-liquid orthogonal diaphragm air cooler, and the external air also enters the open-type circulating water-air-liquid orthogonal diaphragm air cooler. The air flow channel in the air cooler forms the dry hot air entering the mixed air chamber of the main body of the cooling tower, and the spray water enters the water collection tank through the water flow channel of the open circulating water gas-liquid orthogonal membrane plate air cooler and then enters the secondary water distribution system, which distributes water to the countercurrent fill. The dry and cold air enters from under the counter-current packing, and exchanges heat with the water sprayed by the secondary water distribution system inside the counter-current packing to form hot and humid saturated air, which passes through the counter-current water collector and enters the mixed air chamber of the main body of the cooling tower and the hot and humid saturated air After mixing, hot and humid unsaturated air is formed, which is discharged out of the cooling tower by the fan at the top of the tower. The cross-flow part realizes the air-cooling function, and the counter-flow part realizes the wet-cooling function.

The cooling tower of the present invention adopts an open circulating water-air-liquid orthogonal membrane plate air cooler to separate the air channel and the water channel. The cooling tower is operated jointly by the air cooling section and the wet cooling section, and the circulating water passes through the dry section to dissipate heat through conduction The temperature is lowered. Since the air and water channels are isolated, there is no evaporation of water in this process, that is, there will be no loss of water; when water flows through the wet section, only the rest of the temperature difference needs to be reduced. That is to say, the water lost from the cooling tower of the present invention is only produced by countercurrent flow or part of the heat load of the wet cooling section. Since this heat load is lower than that of the existing cooling tower, water can be saved. Because the unsaturated hot and dry air at the outlet of the dry section is mixed with the saturated hot and humid air in the wet section, the mixed air is not saturated, and its moisture content is much smaller than that of the existing cooling tower, which eliminates the visible fog group and reduces the fog haze. The open circulating water-air-liquid orthogonal membrane plate air cooler of the present invention adopts plastic non-metallic materials, overcomes the problem of corrosion, and minimizes the load of the cooling tower at the same time. The air-cooling section and the wet-cooling section of the open-type circulating water-gas-liquid orthogonal membrane plate air cooler of the present invention can also be adjusted and run independently. Because the cooling tower is running, it is inevitable that fungi will grow in the water and adhere to the wet-cooling part or the air-cooling part together with the silt. , which will lead to a decrease in heat transfer efficiency and a multiplied increase in load; when the temperature drop of the circulating water in the dry section can meet the process temperature requirements, the water distribution in the wet section can be closed. When there is no water flow, the bacteria and algae will also be lost. The living conditions are conducive to the cleanliness and efficiency of the heat exchange device.

Because the design of the present invention adopts the above-mentioned technical scheme, countercurrent tower and cross-flow tower technologies are comprehensively used, and the combination of air cooling and wet cooling is preferably used. The technical solution of the combined operation of the two modes effectively solves the problems of clumsy overall structure, waste of water resources and short operation period of the existing industrial circulating water cooling towers. After several tests, the results show that compared with the existing technology, it has the advantages of simple and practical overall structure, joint operation of air-cooling section and wet-cooling section, water saving and fog elimination, low cost, long operating cycle, and convenient use. It is suitable for Cooling device for industrial circulating water.
