Cooling water circulation system of calcining coke cooler

[0002] Needle coke is a high-quality variety that is vigorously developed among carbon materials. Its appearance is a silver-gray porous solid with metallic luster. The width ratio is like a fibrous or needle-like texture, and it feels smooth to the touch. It is the raw material for the production of high-end carbon products such as ultra-high-power electrodes, special carbon materials, carbon fibers and their composite materials. Due to the needle coke after calcination The temperature is very high. In the prior art, it is generally cooled by a rotary cooler. The water spraying device directly sprays water on the high-temperature needle coke in the cooler for cooling and sprays water on the cylinder of the cooler for cooling. Because the cooling water Direct contact with high-temperature needle coke will cause a reaction, which reduces the quality and output of needle coke. Therefore, some manufacturers refer to the principle of the drum slag cooler and use jacket water circulation to cool the hot coke through a membrane cold coke machine. , can effectively avoid the direct contact between the cooling water and the high-temperature needle coke, and the heat is absorbed by the water in the barrel wall of the film-type cold coke machine, thereby cooling the high-temperature needle coke. However, the high-temperature water after heat exchange needs to be cooled rapidly , to be able to achieve the purpose of recycling. In the prior art, the cooling cycle of high-temperature circulating water is mostly carried out through the cooling tower. The existing cooling tower structure is relatively simple. During the cooling operation, the water consumption is large and the heat exchange and cooling efficiency is not good. High, the waste of heat is relatively serious, and it is easy to generate a large amount of fog, which affects the quality of the surrounding environment of the factory. In view of this, in-depth research on the above problems led to this case.
