A kind of flash vaporization kettle
Technical field
The utility model relates to a kind of chemical production equipment, is specifically related to a kind of flash vaporization kettle.
Background technology
In modern chemical industry production, some reaction is step reaction, needs cleaning reactor rapidly and efficiently, and for next time produces ready, this just requires that product can be cleared out fast.Such as polyacrylic production process is batch (-type), production cycle is approximately 4 hours once, the polypropylene of output is transported to flash vaporization kettle by propylene polymeric kettle, bottom discharge mouth discharging directly from flash vaporization kettle after flash vaporization kettle completes flash distillation, if therefore the fast also less residue of the discharging speed of flash vaporization kettle will save the production time, also greatly reducing the workload of cleaning still simultaneously.
Based on the problems referred to above, a kind of novel flash vaporization kettle of design invention, can clear up reactor fast, just seems particularly necessary.
Summary of the invention
For the deficiencies in the prior art, the invention provides the flash vaporization kettle that a kind of structure is simple, reasonable in design.Product after the present invention can effectively ensure flash distillation is separated with still wall, and make product flow out flash vaporization kettle fast, residual quantity is little, and then reduces the workload of clear still work, enhances productivity, reduces production cost.
The concrete technical scheme that the utility model is taked is: a kind of flash vaporization kettle, comprise enclosed kettle, the upper end of kettle is provided with motor, the lower end of motor is connected with positioner, the lower end of positioner is connected with shaft, and it is inner that shaft inserts kettle; The upper end of kettle is provided with feed liquid port and thermometer socket, and it is inner that thermometer inserts kettle by thermometer socket, for measuring kettle inner heat reaction temperature; The bottom of kettle is provided with material liquid outlet; Autoclave body bottom is provided with inflating device;
Described inflating device, comprises aerostatic press, and described aerostatic press connects on gas supervisor by interface, and gas supervisor circularizes the outside being looped around kettle, and gas supervisor is at least two, and gas supervisor is evenly distributed in the outside of kettle; Gas service pipe is connected between gas supervisor and kettle, and the described upper gas service pipe connected of every bar gas supervisor is at least 4, and gas service pipe is symmetrically arranged with kettle between two.
After material enters flash vaporization kettle, aerostatic press squeezes into high voltage protective gas by interface to gas supervisor, and protective gas enters in flash vaporization kettle by gas service pipe, and now protective gas can make the portioned product of production can not paste on the inwall of kettle; Annular due to gas supervisor is arranged and the symmetrical expression design of gas service pipe, makes gas momentum that inner wall of kettle all directions are subject to even, can ensure that the product in all directions of kettle inside can be got off by gas shock; After question response is complete, opens discharging opening and release product, after product major part flows out, strengthen the pressure of protective gas with the frequency of 10-12 time per minute, finally make the disposable recovery of product 99.9%.
In sum, adopt flash vaporization kettle provided by the utility model, discharging speed can be improved fast, and make and less residue, effectively can save the production time, also greatly reducing the workload of cleaning still simultaneously.

In figure, 1 is thermometer, and 2 is shaft, and 3 is gas supervisor, and 4 is gas service pipe, and 5 is material liquid outlet, and 6 is liquor inlet, and 7 is positioner, and 8 is motor, and 9 is thermometer socket, and 10 is interface.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the schematic diagram of flash vaporization kettle, and a kind of flash vaporization kettle comprises enclosed kettle, and the upper end of kettle is provided with motor 8, and the lower end of motor 8 is connected with positioner 7, and the lower end of positioner 7 is connected with shaft 2, and shaft 2 inserts kettle inside; The upper end of kettle is provided with feed liquid port 6 and thermometer socket 9, and thermometer 1 inserts kettle inside by thermometer socket 9, for measuring kettle inner heat reaction temperature; The bottom of kettle is provided with material liquid outlet 5; Autoclave body bottom is provided with inflating device;
Described inflating device, comprises aerostatic press 11, and described aerostatic press 11 connects on gas supervisor 3 by interface 10, and gas supervisor 3 circularizes the outside being looped around kettle, and gas supervisor 3 is at least two, and gas supervisor 3 is evenly distributed in the outside of kettle; Gas service pipe 4 is connected between gas supervisor 3 and kettle, and the gas service pipe 4 that described every bar gas supervisor 3 connects is at least 4, and gas service pipe 4 is symmetrically arranged with kettle between two.
After material enters flash vaporization kettle, aerostatic press squeezes into high voltage protective gas by interface to gas supervisor, and protective gas enters in flash vaporization kettle by gas service pipe, and now protective gas can make the portioned product of production can not paste on the inwall of kettle; Annular due to gas supervisor is arranged and the symmetrical expression design of gas service pipe, makes gas momentum that inner wall of kettle all directions are subject to even, can ensure that the product in all directions of kettle inside can be got off by gas shock; After question response is complete, opens discharging opening and release product, after product major part flows out, strengthen the pressure of protective gas with the frequency of 10-12 time per minute, finally make the disposable recovery of product 99.9%.
In sum, adopt flash vaporization kettle provided by the utility model, discharging speed can be improved fast, and make and less residue, effectively can save the production time, also greatly reducing the workload of cleaning still simultaneously.
