Description
Technical field
The utility model belongs to the chemical plant field, relates to a kind of phosphorus trichloride production and uses chlorine liquid carburetor, is specifically related to a kind of novel phosphorus trichloride production with box comb vaporizer.
Background technology
The liquid chlorine vaporization is the primary operation in producing with chlorine, and liquid chlorine is low-pressure liquefied property severe toxicity gas, belongs to the dangerization article.The main unsafe factor that exists has: 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 electrolytic reaction with the refined brine that contains ammonium ion, then ammonium ion then with electrolysate chlorine generation chemical reaction, generate nitrogen trichloride, and get into the liquid chlorine production system together with chlorine.When chlorine was liquefied, nitrogen trichloride also was liquefied and sneaks in the liquid chlorine.When using chlorine, can store the nitrogen trichloride that together liquefies and bring when bottling in the gasifying pot gradually by chlorine gas liquefaction.And the boiling point of nitrogen trichloride is than the boiling point of liquid chlorine high (nitrogen trichloride boiling point＜71 ℃), liquid chlorine boiling point-34.6 ℃).The explosion hazard content of nitrogen trichloride is 5% in the liquid chlorine.When liquid chlorine in the gasifying pot is constantly vaporized; Nitrogen trichloride is not then vaporized or is vaporized not exclusively, goes down for a long time, can form nitrogen trichloride and gather and can reach finite concentration; And under certain condition (like vibration, sunlight, organism effect etc.), then possibly 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 surge tank, 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 gets into is with the gasifying pot of heating jacket 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 (like BW T, hot water pump etc.).And, can only adopt a plurality of chlorine bottle parallel connections when the evaporating capacity that needs to improve chlorine, perhaps give the heating of chlorine bottle; Like water spray, electric furnace, ir lamp baking etc., not only expense is high especially, and is absolutely unsafe; Sometimes Yin Wendu raises; Pressure also rises thereupon, exceeds pipe safety withstand voltage scope, too security incident can take place.
In existing production, also there is the box comb vaporizer of employing to vaporize; But existing chlorine liquid carburetor tubulation is prone to the perforation that is corroded in use, and this mainly is that defective, steam heating mode make that the corrodibility of water quality variation, water strengthens owing to itself just existing in the apparatus processing manufacturing, oxygen in water causes galvanic corrosion, discontinuous production to cause reason such as settling place corrosion to be brought.Can safety and stability guarantee the required chlorine of phosphorus trichloride production when therefore how to guarantee the liquid chlorine vaporization, the gathering of nitrogen trichloride in the minimizing system, and guarantee the stable of liquid chlorine vaporization equipment, in the daily production of enterprise, seem particularly important.
Summary of the invention
The purpose of the utility model is the above-mentioned deficiency to prior art, provides a kind of novel liquid chlorine vaporizing with anticorrosion box comb vaporizer.This device adopts electric heating device heating Evaporating Heat Transfer WATER AS FLOW MEDIUM, in accurate temperature controlling, has avoided in the steam heating process water quality deterioration to WATER AS FLOW MEDIUM, and has adopted and in WATER AS FLOW MEDIUM, add pH value and the antiseptic property that corrosion inhibiting and descaling agent improves water.
The technical scheme of the utility model is:
A kind of novel liquid chlorine vaporizing is with anticorrosion box comb vaporizer; This box comb vaporizer mainly by casing be positioned at the intravital comb of case and form; Laterally the level pipe section of the comb of serpentine tube structure be positioned at casing and bending tube section outside casing; Bending tube section and horizontal pipeline section are in the casing external welding, wherein: in said casing, be provided with the electric heating device of heating medium water, the water inlet on said casing is provided with the corrosion inhibiting and descaling agent charging box.Said electric heating device is controlled by automatic temperature control.
This automatic temperature control control comprises that hygrosensor, temperature show regulation system and temperature converter.The casing of box comb vaporizer is provided with hygrosensor, and said hygrosensor shows that through the outer temperature of casing regulation system links to each other with the intravital electric heating device of temperature converter and case.
Also be provided with the water level liquidometer on the said casing, said water level liquidometer adopts the implosion guard pipe coupling.Top at said casing is provided with riser, is provided with water port in the bottom of said casing.
Said water level liquidometer adopts the implosion guard pipe coupling.
The beneficial effect of the utility model:
This device utilizes electric heating device heating Evaporating Heat Transfer WATER AS FLOW MEDIUM; In accurate temperature controlling, avoided adopting in the process of steam heating WATER AS FLOW MEDIUM water quality deterioration, and adopted and in WATER AS FLOW MEDIUM, add pH value and the antiseptic property that corrosion inhibiting and descaling agent improves water WATER AS FLOW MEDIUM.
The utility model adopts the discharging of liquid chlorine cylinder liquid phase, adopts box calandria vaporizer that liquid chlorine is vaporized, and can avoid directly steel cylinder being heated, and remaining nitrogen trichloride amount is wanted much less than cylinder formula vaporizer.
The intravital comb in box comb vaporizer railway carriage or compartment does not have weld seam; The expansion pipe is made; Its weld seam design elbow envelope outside, thus can avoid in the prior art comb is dipped in the potential safety hazard because of being heated with the leakage of inside and outside two sides corrosion generation liquid chlorine of weld seam in the hot water fully.
