An energy-saving closed cooling tower

Abstract

The invention provides an energy-saving closed cooling tower. The energy-saving closed cooling tower comprises a box, heat exchangers, a high-pressure micro-mist cooling system, an induced air device and water tanks, wherein the heat exchangers are mounted in the box, the high-pressure micro-mist cooling system is used for cooling the heat exchangers, and the induced air device and the water tanks are mounted on the top and the lower portion of the box respectively. The box is a square box or a V-shaped box. The high-pressure micro-mist cooling system is located on the outer sides of the heat exchangers. The heat exchangers comprise at least one heat pipe exchanger, and the heat pipe exchangers are mounted on the two sides of a box body of the square box or form a V-shaped structure to be mounted on the two sides of the V-shaped box. The heat pipe exchangers are two-phase thermal siphon heat exchangers, and the starting temperature is smaller than or equal to 40 DEG C. The evaporation sections of the heat pipe exchangers are mounted inside the water tanks. The energy-saving closed cooling tower has the advantages that heat exchange efficiency is high, water and electricity can be saved, freeze-proofing can be achieved, environmental pollution is avoided, zero pollution and zero emission can be achieved as well, and the intake air temperature can be lowered in summer; by the adoption of the unitization structure, industrial production is facilitated, and cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of industrial cooling equipment, and in particular relates to an energy-saving closed cooling tower. Background technique [0002] Cooling towers are divided into open cooling towers and closed cooling towers. The main disadvantages of the open cooling tower are as follows: First, the water consumption is large. In addition to the effective loss of the heat of the circulating water absorbed by evaporation and vaporization, there is also a part of the invalid loss of the wind blowing loss; the second is the high power consumption. From the heat exchanger The cooling water flowing out still has a residual pressure of more than 20 meters, which becomes normal pressure after entering the cooling tower, and this part of the head energy is wasted. Breeding fungi, in order to reduce scaling in water, measures of dosing and sewage are usually required; Fourth, the life of the heat exchange equipment is short, becau...

Problems solved by technology

The main disadvantages of the open cooling tower are as follows: First, the water consumption is large. In addition to the effective loss of the heat of the circulating water absorbed by evaporation and vaporization, there is also a part of the invalid loss of the wind blowing loss; the second is the high power consumption. From the heat exchanger The cooling water flowing out still has a residual pressure of more than 20 meters, which becomes normal pressure after entering the cooling tower, and this part of the head energy is wasted. Breeding fungi, in order to reduce scaling in water, measures of dosing and sewage are usually required; Fourth, the life of the heat exchange equipment is short, because the water is directly in contact with the atmosphere, the water quality is easy to deteriorate, and the hardness increases, resulting in scaling of the heat exchange equipment, Corrosion reduces the heat transfer effect and shortens the life of the equipment; fifth, the maintenance cost is high, the packing of the cooling water tower needs to be replaced regularly, and the dosing cost is also high, and the annual dosing fee is about 134 yuan / ton of water; the sixth is to reduce production capacity, The circulating water quality of the open cooling tower is complex, which is easy to corrode other heat exchangers in the process, shorten the maintenance cycle of other heat exchangers in the entire process, and increase maintenance costs

However, the heat pipe negative pressure cooling tower has a complex structure, a large investment, is affected by various factors during operation, is unstable, and consumes a lot of energy
