The invention relates to a nitrogen direct cooling and cooling water cooling combined cooler and a cooling technology. The cooler comprises a lower flange, two short water cooling devices, two long water cooling devices, a square barrel, an upper flange and two nitrogen direct cooling devices. The two ends of the square barrel are connected with the upper flange and the lower flange correspondingly. The two short water cooling devices and the two long water cooling devices are arranged on outer wall plates on the periphery of the square barrel correspondingly. One of the two nitrogen direct cooling devices is arranged at the lower end of the square barrel, and the other of the two nitrogen direct cooling devices is arranged at the upper end of the square barrel. A cryogenic nitrogen directcooling and cooling water cooling combined mode is adopted for performing heat exchanging with high-temperature solid materials, the cooling effect is greatly improved, the heat exchanging efficiencyis high, the heat exchanging effect is good, heat exchanging equipment is not prone to blockage, the maintenance frequency and time can be reduced, and the normal production demand is met.
Description
technical field [0001] The invention relates to a heat exchange device in the technical field of chemical industry, in particular to a nitrogen direct cooling and cooling water combined cooler and a cooling process. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. Due to the poor fluidity of solid materials and poor thermal conductivity, the current conventional heat exchange equipment is easy to block, it is difficult to complete the cooling or heating process efficiently, the heat exchange efficiency is low, the heat exchange effect is poor, and the maintenance and repair frequency of heat exchange equipment High, long...
