Abstract
The utility model belongs to the field of chemical equipment, relating to a box-type exhaust pipe carburetor for phosphorus trichloride production. The carburetor is mainly composed of a box body and an exhaust pipe positioned in the box body, wherein the exhaust pipe is in a transverse coiled pipe structure. The horizontal pipe segment of the coiled pipe structure of the exhaust pipe is positioned in the box body, the bent pipe segment of the coiled pipe structure of the exhaust pipe is positioned out the box body, and the bent pipe segment and the horizontal pipe segment are welded out the box body. The exhaust pipe in the box body of the box-type exhaust pipe carburetor has no welding, the welding is designed at an elbow out the box body, and therefore the box-type exhaust pipe carburetor can avoid the safe hidden trouble in the prior art that the exhaust pipe is completely dipped in hot water and welded joints are heated to corrode with the inner surface and the outer surface to leak liquid chlorine. The box-type exhaust pipe carburetor has the advantages of simple structure, easy operation, safety and reliability.
Description
Technical field
The utility model belongs to the chemical industry equipment field, relates to a kind of phosphorus trichloride production chlorine liquid carburetor, is specifically related to a kind of phosphorus trichloride production with box comb vaporizer.
Background technology
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 electrolytic reaction with the refined brine that contains ammonium ion, ammonium ion then with electrolysate chlorine generation chemical reaction, generate nitrogen trichloride.The latter enters 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 much higher (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, and in the course of time, nitrogen trichloride will enrichment gathers and reaches finite concentration, and under certain condition (as vibration, sunlight, organism 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 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 enters 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 (as hot-water cylinder, hot water pump etc.).
Application number is that 96226485.7 utility model patent discloses a kind of chlorine liquid carburetor, this vaporizer is made up of liquid chlorine passage and indirect heating apparatus, stainless steel helix tube places the hot water of cylindrical level land flat cover cylinder of steel, by automatically controlled heating unit being set in steel pipe or the heat in the cylinder of steel being incubated in 60～70 ℃ in the mode that steel pipe adds jacket steam heating, liquid chlorine from stainless steel helix tube by obtaining vaporization.But the stainless steel helix tube of this chlorine liquid carburetor is immersed in the hot water fully, and the weld seam of stainless steel helix tube is subjected to the corrosion of inside and outside two sides, and the possibility of the leakage that liquid chlorine is revealed is very high.
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, the rational liquid chlorine gasification process equipment of design safety is very main.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of phosphorus trichloride production with box comb vaporizer.
The technical solution of the utility model is:
A kind of phosphorus trichloride production is with box comb vaporizer, this vaporizer is mainly by casing be positioned at the intravital comb of case and form, comb is horizontal serpentine tube structure, the level pipe section of described comb serpentine tube structure is positioned at casing, the bending tube section of comb serpentine tube structure is outside casing, and bending tube section and horizontal pipeline section are in the casing external welding.
The casing of described box comb vaporizer is provided with thermometer; Casing is communicated with the steam supply pipeline of steam supply equipment.
Described box comb vaporizer also is provided with a water level liquidometer, water-in, overflow port, bottom half and is provided with water port.
The beneficial effects of the utility model:
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 fully weld seam in the hot water because of being heated and the potential safety hazard of inside and outside two sides corrosion generation liquid chlorine leakage.
The utility model adopts the mode of logical steam that the intravital hot water of case is heated, and can safety and stability guarantee the required chlorine of phosphorus trichloride production.
In sum, simple in structure, the easy handling, safe and reliable of the utility model.
