Novel noise reduction and bacteriostasis method for water cooling tower

Abstract

The invention discloses a novel noise reduction and bacteriostasis method for a water cooling tower. According to the invention, high-density polyethylene vacuum plastic balls which can completely cover the surface of a water pool and float on the water surface and a filter screen provided with a drain outlet and a high-water-level overflow port are put into pool water of the water cooling tower; the high-density polyethylene vacuum plastic balls are resistant to impact, can absorb sound and are not corroded, the round surface characteristic of the balls can change the impact direction of water drop falling, sound generated when water drops beat the water surface is reduced, and water spraying noise of the water cooling tower is reduced; the sphere covers the surface of a water body, so that irradiation of the sun to microorganisms in the water is isolated, photosynthesis of the microorganisms is shielded, biosynthetic chains of the microorganisms and bacteria and algae are blocked, and the function of inhibiting bacteria and algae breeding is achieved. The method has the advantages of low material cost, simplicity in use, no site requirement, long service life of the plastic ball, good reliability, acid and alkali resistance, no exposure, small loss after long-term use, almost no maintenance, wide popularization and application, reduction of water vapor evaporation and blowing loss, water saving and energy saving.

Problems solved by technology

[0002] In recent years, with the continuous improvement of national environmental protection requirements, industrial noise has also been included in the assessment system, and relevant national standards have been formulated. Large-scale wet-cooled industrial cooling towers such as power plants, fertilizer plants, chemical plants, oil refineries and pharmaceutical plants are all There are cooling water towers, and office buildings and hotels also have cooling water towers for air conditioning. The water after heat exchange needs to be cooled quickly and reused. During the cooling process, the warm water is generally raised to a sufficient height and sprayed into the pool below through the water spray tray. When water droplets fall, they slap the water surface and generate noise, which has a great impact on the environment of residents working and living nearby. The Environmental Protection Bureau has received such complaints. In order to reduce noise, the above-mentioned enterprises installed sound insulation walls around the cooling water towers that are higher than the shower trays. These The sound insulation wall needs a ground space for construction and high investment costs. When encountering strong winds, the sound insulation wall is likely to be blown over and blown away. The sound insulation wall may be damaged, or the vehicle or pedestrian under the wall may be injured. Safety It is not high, and the noise reduction effect of the sound insulation wall does not exceed 10%. It also blocks the air induction line of the cooling water tower and reduces the working efficiency of the cooling water tower, so there has been no better solution for everyone to implement

[0003] Because the temperature of the circulating cooling water is very suitable for the growth of bacteria and microorganisms, coupled with sufficient sunlight, the bacteria and microorganisms in the water multiply rapidly, and the microorganisms will metabolize in the water to produce slime, which will reduce the heat transfer efficiency when the slime adheres to the surface of the heat exchange equipment , will also cause under-scale corrosion to damage the equipment. When the bacteria and algae are serious, it is necessary to add chemicals such as fungicides to the water body, which will have a negative impact on environmental protection and staff.

[0004] The past processing methods in the past are time-consuming and labor-intensive than this technical solution, and the economy is obviously insufficient
