Description
Technical field
The utility model relates to the complete vaporization cold energy recovering device of a kind of liquid chlorine.
Background technique
In chemical process, common liquid chlorine vaporization device has tubular type and autoclave two kinds, and vapourizing temperature major part controls at normal temperature, agene at this temperature in liquid chlorine cannot be vaporized, cause savings, particularly autoclave vaporizer, be easy to blast and cause security incident.Therefore national security supervision general bureau explicitly calls for superseded autoclave gasification process about printing and distributing in the notice of eliminating and falling behind safety technical equipment catalogue (2015 first), adopts the full gasification process of tubular type tube still type heating liquid chlorine.But simple adopt this technique, can bring three negative effects, a heat load being the increase in chlorination reactor, because chlorination reaction major part is exothermic reaction, the raising of chlorine temperature can fast reaction speed, increases thermal discharge, needs the heat removed to increase.Two is cannot reclaim with (cold) the latent heat of vaporization of liquid chlorine, the vaporization heat of liquid chlorine is 20.495KJ/mol(-34.1 DEG C), namely the vaporization heat of liquid chlorine per ton is 288.66MJ, be the refrigerator of 80kw as consumption per hour one ton of chlorine is equivalent to a refrigerating capacity, calculate about 3 by general refrigerator Energy Efficiency Ratio, need consumption of electric power to be about 27kw.Three is high temperature when entirely vaporizing, and need consume the heat such as steam or hot water, liquid chlorine per ton of vaporizing needs the steam of about 120kg.
At present, major part producer, because device is backward and liquid chlorine consumption is less, all do not recycle the latent heat of vaporization of liquid chlorine, and nearly all Chemical Manufacture all must use refrigeration equipment, recycling the latent heat of vaporization of liquid chlorine, is an extraordinary energy saving way.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, fully can reclaim cold during liquid chlorine vaporization, and can vaporize completely to the agene in liquid chlorine, thoroughly eliminate the complete vaporization cold energy recovering device of liquid chlorine of the potential risk in liquid chlorine vaporization process.
Technical solution of the present utility model is:
The complete vaporization cold energy recovering device of a kind of liquid chlorine, is characterized in that: comprise low temperature chlorine liquid carburetor, arranges high temperature enhanced vaporization device after low temperature chlorine liquid carburetor; Described low temperature chlorine liquid carburetor comprises shell, and outer casing underpart arranges freezing liquid import, and shell upper arranges freezing liquid outlet, arranges upper and lower supervisor, arrange the volute of multiple parallel connection between upper and lower supervisor in shell; The entrance point of lower supervisor is connected with liquid chlorine cylinder, and the primary outlet of lower supervisor connects alkali liquor absorption tank, and the sub-outlet of lower supervisor connects the looped pipeline stretched in high temperature enhanced vaporization device; Upper supervisor, by being installed on the extension tube in high temperature enhanced vaporization device, connects Chlorine Buffer Vessel; Described high temperature enhanced vaporization device comprises housing, arranges volute and hot water in housing, and one end of volute is connected with described extension tube, and the other end of volute is connected with described looped pipeline.
Described extension tube is connected to the safety valve communicated with alkali liquor absorption pipe.
The utility model is rational in infrastructure, fully can reclaim cold during liquid chlorine vaporization, and can vaporize completely to the agene in liquid chlorine, thoroughly eliminates the potential risk in liquid chlorine vaporization process.The utility model eliminates two negative effects that aforementioned full gasification process brings, in recyclable liquid chlorine vaporization process more than 95% latent heat, only need consume the heat of former gasification process about 5%, there is larger power savings advantages.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The complete vaporization cold energy recovering device of a kind of liquid chlorine, comprises low temperature chlorine liquid carburetor 1, arranges high temperature enhanced vaporization device 2 after low temperature chlorine liquid carburetor; Described low temperature chlorine liquid carburetor comprises shell 3, outer casing underpart arranges freezing liquid import 4(freezing liquid and adopts 20% sodium chloride or calcium chloride freezing liquid, chilled liquid temperature is-15 DEG C), shell upper arranges freezing liquid outlet 5, upper and lower supervisor is set in shell, the volute 6 of multiple parallel connection is set between upper and lower supervisor; The entrance point of lower supervisor is connected with liquid chlorine cylinder 7, and the primary outlet of lower supervisor connects alkali liquor absorption tank, and the sub-outlet of lower supervisor connects the looped pipeline 9 stretched in high temperature enhanced vaporization device; Upper supervisor, by being installed on the extension tube 8 in high temperature enhanced vaporization device, connects Chlorine Buffer Vessel; Described high temperature enhanced vaporization device comprises housing 10, and arrange volute 11 and 75 DEG C of hot water in housing, one end of volute is connected with described extension tube, and the other end of volute is connected with described looped pipeline.
Described extension tube is connected to the safety valve 12 communicated with alkali liquor absorption pipe.
The utility model is made up of two groups of vaporizers, and the first order is low temperature chlorine liquid carburetor, and most of liquid chlorine is vaporized at this, general vapourizing temperature controls at about 0 ~-25 DEG C (according to technique needs), because vapourizing temperature is lower, corresponding saturation pressure is also low, so the first order can not arrange safety valve.The second level is high temperature enhanced vaporization device, and import is connected to the bottom of first order vaporizer, and vapourizing temperature is 75 ~ 85 DEG C, liquid chlorine and the agene of small part are vaporized at this, because the liquid chlorine of vaporizing in this vaporizer only has about 5% of total chlorine gas amount, the heat of consumption is little, can ignore.Owing to all adopting pipe type evapourator, eliminate the potential safety hazard that autoclave vaporizer exists.Meet national security supervision general bureau about printing and distributing the relevant requirements of eliminating in the notice falling behind safety technical equipment catalogue (2015 first).Second level vaporizer is provided with safety valve because vapourizing temperature is higher, to prevent from vaporizer being imported and exported Close All by mistake, causes vaporizer tube internal pressure to raise.
