Description

technical field [0001] The invention relates to the technical field of ventilation and cooling, in particular to a structural method and device for transforming a mechanical packing tower into a jet spray energy-saving tower. Background technique [0002] At present, the stock market of old cooling towers in my country's petrochemical, metallurgy, cement, pharmaceutical, textile, paper and other major industrial industries and civil construction industries has reached a scale of 226 million tons per hour, and most of them are mechanical ventilation packing cooling towers. The consumption exceeds 65 billion yuan. If the transformation of the existing old tower into a new type of jet spray energy-saving and environmental protection cooling tower can be effectively promoted, more than 70 billion yuan in electric energy consumption and operation and maintenance costs can be saved every year. [0003] At present, the existing technologies commonly used in the industry are as follo...

AI Technical Summary

Problems solved by technology

[0006] (1) In the existing technology, the structural layout of the standardized small square jet spray energy-saving cooling tower is basically adopted, and the design of the spraying water density is relatively small. Due to the size design of the packing tower, the usable area is relatively small, and some of them are rectangular or even irregular polygonal structures. The concrete beams, columns, partitions, etc. in the tower are staggered. There are many difficulties and structural discomforts in the reconstruction and installation of the existing tower structure.

[0007] (2) The industry, working conditions and water quality of traditional mechanical packing cooling towers in the domestic stock market are quite different. The tower type in the existing technology is only suitable for industry users with better comprehensive working conditions. How to deal with users with thousands of differences in the transformation process The working condition is the difficulty faced by the existing technology

[0008] (3) Most of the medium and large traditional mechanical packing cooling towers in the domestic stock market are concrete steel-concrete structure tower frame structures, the construction cost of the early civil works is relatively high, and the tower frame is intact, which is completely arranged according to the new jet spray energy-saving cooling tower structure , I want users to completely push the old tower to build a new jet spray energy-saving cooling tower. The comprehensive construction cost is still significantly higher than the existing traditional mechanical ventilation packing cooling tower, which is unacceptable to users. This also directly shows that the new jet flow in the existing technology Although the spray energy-saving cooling tower can save energy for users, it cannot meet the expectations of the user's investment payback period. It is necessary to adopt the new method and structural layout design of the old tower transformation

This greatly reduces the acceptance of the industrial application of jet spray energy-saving cooling towers, and also seriously lags behind the process of transforming domestic energy-consuming mechanical packing towers into jet spray energy-saving cooling towers to achieve energy-saving and environmental protection benefits.
