Embodiment Construction

[0015] Below in conjunction with accompanying drawing, patent of the present invention is described further.

[0016] figure 1 Schematic diagram of the structure of the antifreeze, fog, and water-saving cooling tower provided by the present invention when mechanical ventilation is used. The cooling tower includes a tower body 17, a water collector 10, a water distributor 9, a packing layer 7, a water storage tank 5 arranged in the tower body, a packing air inlet louver 6 arranged on the side wall of the tower body below the packing layer, circulating water Water inlet pipe 1, circulating water return pipe 3 and corresponding valves. Air cooler air inlet louvers 12 are arranged symmetrically on the tower body side wall of the cooling tower, and first air coolers 13a and first air coolers 13b are arranged symmetrically on the inside of the tower body close to the air cooler air inlet louvers. A second air cooler 25a and a second air cooler 25b are arranged symmetrically on the...

Abstract

A kind of preventing frostbite, falling fog and water saving cooling tower relates to cooling equipment using for dropping circulating water in temperature. Set air intake blind on each side of top and bottom of tower and set the first and second air-cooling implements near the blind inside the tower. Water distribution pipe of two types of air cooling implements connects with water intake pipe of circulating water, while the outlet pipe connects with distributor and water return pipe of circulating water with by-pass pipe. Collecting water implement sets between tanks under the first air-cooling implement. The cooling of circulating water carries by air-cooling implement and it reduces the cooling load of packed stage and saves water by reducing the amount of evaporation. The exhaust gas is mixture formed by gas from the first air-cooling implement and collecting water implement, whose dew point temperature is lower than the other existing tower to eliminate or reduce the spray of tower and is benefit for environment. The second air-cooling implement increases the cooling load of circulating water in the air-cooling implement to greatly increase water conservation efficiency and warm up the intake air to prevent freezing in winter.

Description

technical field [0001] The invention relates to a cooling tower for circulating water cooling, which can be widely used in various technical fields such as petroleum, chemical industry, textile and thermal power generation. Background technique [0002] The function of the cooling tower is to exchange heat between the circulating water carrying waste heat and the air in the tower, transfer the heat of the water to the air and disperse it into the atmosphere, and cool down the circulating water. Cooling towers are divided into wet cooling towers and dry cooling towers according to the contact mode of circulating water and air. [0003] In the wet cooling tower, the circulating water spread on the surface of the filler is in direct contact with the air, and the heat of the water is transferred to the air through contact heat transfer and evaporative heat dissipation. The heat exchange efficiency of the wet tower is high, and the limit temperature at which the water is cooled ...
