Abstract
The utility model discloses a large-scale chloroactic acid crystallization kettle. The large-scale chloroactic acid crystallization kettle comprises a kettle body and a stirrer, wherein the stirrer can realize speed regulation through a frequency converter, and an electric tracing device is mounted at the bottom of the kettle body. The large-scale chloroactic acid crystallization kettle disclosed by the utility model can improve the effect of cooling chlorination liquid, shorten crystallization time, improve the efficiency of the crystallization kettle, meet the large-scale production requirements, avoid the amplification effect in chemical production and reduce the production of chloroactic acid by increasing cooling area of the chloroactic acid crystallization kettle and performing variable-frequency stirring. The variable-frequency stirring can adopt different speeds according to different time periods, ensure the particle size of the chloroactic acid, further improve the quality of the chloroactic acid and keep the product purity above 98%. Tracing electric heating is adopted at the bottom of the crystallization kettle, and the smooth discharge can be ensured.
Description
Technical field
The utility model relates to a kind of large-scale crystallizing chloroacetic acid device.
Background technology
Domestic crystallizing chloroacetic acid still is generally 2～5m
3, have no 15m
3Above large-scale crystallization kettle.Be subject to the impact of equipment, output per single reactor is lower, and the monoxone quality fluctuation is larger, and the heavy knot of easy crystallization at the bottom of large-scale crystallization kettle still affects crystalline product quality and discharging packing.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model is to provide a kind of chlorated liquid good cooling results, large-scale crystallizing chloroacetic acid still that crystallization yields is high.
Technical scheme: a kind of large-scale crystallizing chloroacetic acid still, comprise kettle, agitator, described agitator is by frequency converter timing, and described autoclave body bottom is installed electric heat tracing device.
By increasing film-cooled heat, improve the chlorated liquid cooling effect simultaneously, shorten crystallization time, for 16m
3Nonstandard crystallization kettle, its film-cooled heat is 33.2m
2For 16m
3The standard crystallization kettle, its film-cooled heat is 29.48m
2.
Beneficial effect: compared with prior art, the utility model has the advantages that by the crystallizing chloroacetic acid still being increased to film-cooled heat, frequency conversion stirring, improve the chlorated liquid cooling effect, shorten crystallization time, improve crystallization kettle efficiency, meet the requirement of maximizing and producing, avoided the enlarge-effect of Chemical Manufacture, reduced the production of chloroacetic acid cost.Frequency conversion is stirred according to the different friction speeds that adopt of time period, guarantees the monoxone granularity, thereby improves the monoxone quality, and product purity remains on more than 98%.The crystallization kettle bottom adopts the heating of companion's thermoelectricity, guarantees that discharging is smooth and easy.
The accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, a kind of large-scale crystallizing chloroacetic acid still, comprise kettle 1, agitator 2, frequency converter 3, electric heat tracing device 4.Frequency converter 3 is connected and installed with agitator 2, according to the different mixing speeds of different employing of time period.Electric heat tracing device 4 is arranged on kettle 1 bottom.
The utility model is mainly for 15m
3Above large-scale crystallization kettle and the architecture advances taked, for 16m
3Nonstandard crystallization kettle, film-cooled heat design is risen to 33.2m
2For 16m
3The standard crystallization kettle, film-cooled heat design is risen to 29.48m
2.
After chlorated liquid enters crystallization kettle, open stirring, frequency converter, according to crystallization processes, by the different periods, regulate mixing speeds.Open cooling water chlorated liquid in crystallization kettle is effectively lowered the temperature, until the blowing temperature, open electric tracing at the bottom of still simultaneously, guarantee that discharging is smooth and easy.
Claims (2)
1. one kind large-scale crystallizing chloroacetic acid still, comprise kettle (1), agitator (2), it is characterized in that: described agitator (2) is by frequency converter (3) speed governing, and electric heat tracing device (4) is installed in described kettle (1) bottom.
2. a kind of large-scale crystallizing chloroacetic acid still according to claim 1, is characterized in that: for 16m
3Nonstandard crystallization kettle, its film-cooled heat is 33.2m
2For 16m
3The standard crystallization kettle, its film-cooled heat is 29.48m
2.
