Square cross flow cooling tower with single-side air intake

Abstract

The invention discloses a square cross flow cooling tower with single-side air intake, which comprises a machine frame, a blow dryer on the top of the machine frame and a fan in the blow dryer; a water spraying device composed of a water spraying basin, a water distributing nozzle, water spraying filling and a water collecting basin is arranged in the internal part of the machine frame; the water spraying basin is located over the water spraying filling; the water distributing nozzle is installed in the water spraying basin; the water collecting basin is arranged below the water spraying filling; the water spraying filling is formed in a manner that a plurality of filling sheets are overlapped; each filling sheet is provided with an air inlet zone, a heat exchanging zone and an air outlet zone in sequence; a protruding ridge is arranged between the adjacent zones for preventing water from spraying; the air inlet zones and the air outlet zones of the adjacent filling sheets are contacted mutually to form honeycomb-shaped air inlets and air outlets respectively; and the water distributing nozzle comprises a main body pipe, a honeycomb duct and a petal-shaped disc which are arranged coaxially. When the square cross flow cooling tower with single-side air intake is applied, uniform water distribution can be realized and the cooling property of the cooling tower can be improved. Air comes into the air inlet of the water spraying filling and goes out of the air outlet and the air goes out of the top surface under the function of the fan. Consequently, the energy consumption of the fan and noise at the top of the tower can be reduced.

Description

technical field [0001] The invention relates to a cooling tower, in particular to a water-saving and energy-saving square single-sided air-inlet cross-flow cooling tower. Background technique [0002] At present, all central air conditioning and circulating cooling water systems for industrial processes are equipped with cooling towers. The function of the cooling tower is to cool down the central air conditioner in operation. During the operation, the cooling water carrying waste heat exchanges heat with the air in the tower, so that the waste heat is transferred to the air and diffused into the atmosphere. The working principle of the cooling tower is that the cooling water in the shower basin flows downward in a linear shape through the water distribution nozzle and splashes into fine water droplets, and then flows into the water collection basin after being filled with water. When the water flow forms a water film and flows down, the cold air relies on the suction forme...

Problems solved by technology

[0003] Generally, square cross-flow cooling towers are often used in central air-conditioning and industrial process circulating cooling water systems, mainly with two-sided air intake, and occupy a large area; even if there is one-sided air intake, due to poor air conduction conditions, increase fan energy consumption

Moreover, the general water-sprinkling packing has no water collection device. When it is installed in a multi-layer shelving type, its floating situation is more obvious. There are obvious water drops falling out of the inner air outlet area of ​​the water-sprinkling packing and falling to the ground, and the outer side of the water-sprinkling packing enters the air. The area will also splash water to the ground, which wastes water resources and cannot ensure a good circulation of cooling water; secondly, the ground around the cooling tower is wet for a long time and there is water flow, which will increase the water replenishment of the cooling tower, which will cause the fan efficiency of the entire system. decrease, power consumption increases, and the power consumption ratio cannot even meet the national standard of not more than 0.035kw / ( m 3 / h)

In addition, the water distributed by the water distribution system composed of shower basins and water distribution nozzles is thick and uneven, which will affect the thermal performance of the cooling tower. The thermal performance is even below 85%, which is not less than 95% lower than the national standard. %
