Description

Non-contact heat exchanger for air separation machine precooling system Technical Field The utility model relates to the technical field of air separation equipment, in particular to a non-contact heat exchanger for an air separation machine precooling system. Background The air separation equipment takes air as a raw material, turns the air into liquid state through a compression circulation deep freezing method, and gradually separates and produces inert gases such as oxygen, nitrogen, argon and the like from the liquid air through rectification, so that the air separation equipment is widely applied to the fields of traditional metallurgy, novel coal chemical industry, large-scale nitrogen fertilizer, professional gas supply and the like. The structure of present air separation equipment includes air compression system, clean system, liquefaction refrigerating system and rectification system, in clean system, the mode that needs to adopt to spray purifies the compressed air of input, wash the sour material that gets rid of in the air, it is required to cool down to the air after compressing before purifying, because under low temperature condition, sour gas (such as SO 2, HCl) solubility in water or alkaline solution is higher, be favorable to reinforcing the washing effect, present clean system lacks the integration with cooling module, be distributed design, on-the-spot through pipeline intercommunication during the installation, on-the-spot personnel's work load has been increased, the skill proficiency requirement is higher after on the scene, secondly present plate-fin radiator is to the cooling effect of compressed air is not good, lead to follow-up washing effect incompletely, therefore need further improvement. Disclosure of utility model In view of the above, it is desirable to provide a non-contact heat exchanger for an air separation unit precooling system. The utility model provides a non-contact heat exchanger for air separation machine precooling system, includes the base, barrel and cooling runner, the barrel is installed on the base, the barrel is syllogic, including the inlet chamber that communicates in proper order, cooling chamber and clean room, the inlet chamber upper end is provided with the intake pipe, be provided with porous fin group and ripple fin group in the cooling chamber, two sets of porous fin group set up respectively at the both ends of ripple fin group, the cooling runner includes branch runner and sprue, branch runner is the U type, a plurality of branch runner is pegged graft in the barrel side by side spaced, and with porous fin group and ripple fin group connect heat transfer, branch runner both ends communicate with two sprue respectively. Preferably, a guide plate is arranged in the air inlet chamber, and the guide plate is obliquely arranged along the air inlet direction of the air inlet pipe. Preferably, a conical guide cylinder is arranged at the joint of the cooling chamber and the purifying chamber, an air outlet pipe is arranged at the top end of the conical guide cylinder in an extending way towards one side of the purifying chamber, and a plurality of air holes are arranged on the air outlet pipe.
