Description

Anti-blocking gas collector for urea catalytic hydrolysis

Technical Field

The utility model relates to a gas collector, the urea catalysis of specially adapted product for the gaseous reactor or reation kettle's of easy absorption, condensation, crystallization area water outlet is hydrolysised and is prevented stifled type gas collector.

Background

In order to improve the gas separation efficiency of a gas collector of an existing urea catalytic hydrolysis reactor, a centrifugal separation device with a cone-shaped structure and the like is additionally arranged at the bottom end of a main cylinder body of the gas collector to remove dust and increase the speed, and gas easily carries salt in solution into a gas output channel of the gas collector. Salt and crystal accumulate for a long time, easily cause the valve on the passageway to block up, and the reason that this phenomenon formed is for the gas-liquid soaks and forms steam and takes the salt altogether, influences the normal use of functional elements such as valve and instrument in the product gas transmission pipeline, leads to card look, corruption, or sealed inefficacy, consequently needs to improve.
