Description
Technical field
The utility model belongs to the chemical industry equipment field, relates to a kind of phosphorus trichloride production liquid chlorine carburetion system.
Background technique
The liquid chlorine vaporization is the primary operation that phosphorus trichloride is produced, and liquid chlorine is low-pressure liquefied property severe toxicity gas, belongs to the dangerization product.Least safe factor is: employed raw material is industrial table salt and water in the chlor-alkali production, keeps away and unavoidably brings ammonium class material into.When carrying out cell reaction with the refined brine that contains ammonium ion, ammonium ion then with electrolysate chlorine generation chemical reaction, generate agene.The latter enters the liquid chlorine production system together with chlorine.When chlorine was liquefied, agene also was liquefied and sneaks in the liquid chlorine.When using chlorine, can store the agene that together liquefies and bring when bottling in the gasifying pot gradually by chlorine gas liquefaction.And the boiling point of agene is than the boiling point of liquid chlorine much higher (agene boiling point＜71 ℃), liquid chlorine boiling point-34.6 ℃).The explosion risk content of agene is 5% in the liquid chlorine.When liquid chlorine in the gasifying pot is constantly vaporized, agene is not then vaporized or is vaporized not exclusively, and in the course of time, agene will enrichment gathers and reaches finite concentration, and under certain condition (as vibration, sunlight, organic substance effect etc.), then may cause the gasifying pot blast.
Liquid chlorine is many, and the vaporization amount of chlorine of steel cylinder self (particularly winter) can not satisfy the production needs sometimes by the discharging of steel cylinder gas phase, often adopts the direct-fired method of steel cylinder, to quicken vaporization.This method might make the liquid chlorine temperature sharply rise, and causes superpressure or safety plug fusing in liquid chlorine cylinder or the knock out drum, causes accident to take place.Also have quite a few enterprise that uses chlorine to adopt steel cylinder liquid phase discharging method.The liquid chlorine that goes out steel cylinder enters is with the gasifying pot of heating resistance collar to vaporize (gasifying pot belongs to third class(grade) pressure vessel), usually logical steam or hot water heating in the chuck.Logical steam can cause the sharply vaporization and wayward of jar interior liquid chlorine; Logical hot water then need increase by a cover hot water circulating device (as hot-water cylinder, hot water pump etc.).
Can safety and stability guarantee the required chlorine of phosphorus trichloride production when therefore how to guarantee the liquid chlorine vaporization, the gathering of agene in the minimizing system, the rational liquid chlorine gasification process equipment of design safety is very main.
