TECHNICAL FIELD

[0001] The utility model relates to a cooling tower technical field especially relates to a cooling tower cleaning and descaling device. BACKGROUND

[0002] Cooling tower, spray pipe, heat exchange pipe, filler and so on will form scale after running for a period of time, and the more scale will affect the heat exchange effect. The inside of the spray pool will also produce silt and sediment, which will affect the spray effect and increase the tendency of scaling in the cooling tower. With the development of society, heat exchange equipment is widely used in refrigeration, power, chemical industry and other fields, among which the cooling tower is one of the most common heat exchange equipment. The cooling tower is mainly composed of a tower body, a motor, a fan, a filler and a water distribution device. Its working principle is mainly to use the contact between water and air to dissipate heat in industrial or air conditioning systems through evaporation. Therefore, it is crucial to ensure the heat transfer performance in the air-water flow area of the cooling tower to improve its efficiency. According to investigations, more than 90% of heat exchangers have scaling problems, and the cooling tower as a heat exchange equipment is no exception. Scaling refers to the slow accumulation of solid substances on the surface of objects in contact with the medium in the medium flow area. The thermal conductivity of scaling is extremely low, which seriously affects the heat exchange performance of the heat exchange equipment and increases the operation and maintenance cost of the equipment.

However, in practical engineering applications, factors such as cost, maintenance, and technical level of operators must be considered. Once scaling occurs, it will develop rapidly, and scaling will inevitably occur in practical applications. In some practical engineering, water treatment equipment or scale inhibition devices are installed, but good results have not been achieved. UTILITY MODEL CONTENT
