Automatic temperature control circulating water supply system
Technical Field
The utility model relates to a circulating water supply equipment technical field especially relates to an automatic accuse temperature circulating water supply system.
Background
The circulating water mainly comprises industrial circulating water and household circulating water, and the main purpose is to save water. Industrial circulating water is mainly used in cooling water systems, and is also called circulating cooling water. The circulating cooling water is divided into a closed type (closed type) and an open type. In a closed cooling water system, cooling water is not exposed to air, water loss is little, and the contents of various minerals and ions in the water are not changed generally. The circulating water plays a very important role in chemical production, is a main refrigerant medium of each heat exchange device and a main cooling medium of dynamic equipment, and the circulating water pump capable of supplying the circulating water is widely applied in the field of chemical production and is important equipment in the chemical production. Along with the implementation of the policy of 'energy conservation and emission reduction' and 'high pressure and low pressure' on thermal power generating units in China, the urban centralized heat supply system taking a thermal power plant provided with a high-capacity steam extraction and condensation type unit with good economy and strong load adaptability as a heat source is increasingly common in the 'three north' region of China. The thermal power plant is assisted with an absorption heat pump to recover the waste heat of circulating water, so that the transformation of energy conservation and efficiency improvement is realized. Because the temperature is low in northern areas in winter, the temperature of circulating water is difficult to meet the requirements of equipment on water temperature and water flow, the problems of freezing of a cooling tower, performance guarantee of a heat pump, optimized running of the circulating water and the like caused by the temperature are more obvious, the failure rate of the equipment is high, the maintenance cost and the production cost are greatly increased, and the economic benefit is reduced.
