Abstract
The utility model relates to a primary cooler equipment for being directed at coke oven high temperature coal gas carries out refrigerated. The light tube dividing wall heat exchange element adopted by the traditional primary cooler is changed into a three-line spiral corrugated heat exchange tube. Therefore, the heat exchange area of the heat exchanger is effectively increased, the original laminar flow heat exchange state is changed into a semi-turbulent flow state, the total heat exchange coefficient of the heat exchanger is obviously improved, the heat exchange capacity of the primary cooler is effectively increased, or the number of the heat exchange tubes of the primary cooler using the same heat exchange capacity can be reduced by more than 20%, the manufacturing cost is correspondingly reduced, and a large amount of cooling water can be saved.
Description
The utility model relates to a kind of primary cooler equipment that coke-stove gas is cooled off.
For the coal gas of high temperature that is come out by coke oven is cooled off, the coke-oven plant achieves the goal by coal gas primary cooler, but known primary cooler all is to adopt bright and clean seamless steel pipe as the partition heat exchange element.To the primary cooler of same service condition,, just can only strengthen heat exchange area and improve the coefficient of heat transfer if will improve its exchange capability of heat again because of its heat exchanger tube material of selecting for use, caliber, wall thickness, medium, flow velocity etc. are all identical.The heat exchange area of present large-scale primary cooler is up to 4800 square metres, and the ton surplus in the of 190 that weighs if strengthen heat exchange area again, will bring great difficulty to manufacturing, transportation and installation.
The technical solution of the utility model is with bright and clean seamless steel pipe surface, becomes three-way helical bellows (seeing accompanying drawing) through pressure processing, so just can make the primary cooler heat exchange area of same number of tubes increase 10-20%; Simultaneously, making the media flow state in the heat exchanger tube again is curve and half turbulence state by typical parallel laminar motion, makes the interlayer attenuation of laminar flow limit, limit interlayer thermal resistance reduces, turbulence level strengthens, and has improved the hotting mask coefficient, thereby has increased total coefficient of heat transfer K value (can increase more than the 20-30) effectively.
Owing to taked such scheme, the exchange capability of heat of primary cooler is greatly improved, the primary cooler heat exchange original paper material of same exchange capability of heat is saved more than the 20-30%, thereby also reduced the manufacturing cost of primary cooler effectively and saved a large amount of cooling waters.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is the helical fissure pipe after pressure processing.
1. accompanying drawing is tube sheet.
2. accompanying drawing is corrugated tube.
In the accompanying drawings, illustrated that heat exchanger tube becomes the situation for the helical fissure pipe after pressure processing, to the seamless pipe of Ф 57 * 3.5 commonly used, employing pitch is that the triple thread about 20mm is advisable, the indent degree of depth should be between 3～6mm, and heat exchange area then can increase 10-20%.
Coal gas primary cooler is except that being replaced by light pipe the bellows, and other concrete structure does not change, and repeats no more here.
Claims (2)
1, a kind of coal gas primary cooler is characterized in that having adopted spiral bellows as the partition heat exchange element, and bellows is fixed on equipment both sides and the tube sheet by welding or expanded joint.
2, coal gas primary cooler according to claim 1 is characterized in that having adopted the helical fissure pipe as partition heat exchange original paper.
