In rectification tower the meeting in producing a course produces waste gas of many high temperature, this part waste gas is to accord with those who discharge a standard below normal circumstance, but if the situation is unusual, need to introduce the ability after be being handled with purifying device of dust catcher of type of bag of pulse of craft form a complete set to discharge. But the limitation as a result of craft, cannot undertake handling to its directly, settling way is mix into mixes a large number of cold air to undertake dropping in temperature. For this, technical personnel hope can find a kind of skill with conform to of off-gas treatment of high temperature of processing rectify tower.
Had positive result eventually through ceaseless research, be sparge refrigeration technology then apply, the implementation of this technology needs to evaporate sends a few shares such as system of device of cooling tower, sparge, control. To achieve the use result of beautiful, above all the design of vapour refrigeration tower must reasonable, no matter be a structure,on still is solvent respect. It is the choice of sparge device next, the material that includes spray head, installation is decorated, operation control means is waited a moment. Using evaporate to send purpose of pilot of cooling tower system is to make sure flue gas outlet temperature is inside set value scope, and to achieve this one goal, the system should have self-adjusting function, filter function, realize the automatic switch of loop. Can prove from practice, sparge refrigeration system is handling flue gas of rectification tower high temperature to remove dust the application in the system is very effective, the investment that handles flue gas discharge, economic system collecting dust to reducing a system and energy-saving fall bad news has enormous sense.
