Description
Technical field
The invention belongs to the chemical industry technical field of heat exchange, supply gallic acid decarboxylic reaction, the evaporation of reaction product pyrogallic acid and condense to reclaim to use.
Background technology
Existing pyrogallic acid production ties up in a static reacting by heating cylindrical shell of batch (-type) and the static condenser to be carried out; Disposable throwing gallic acid powder shape raw material is established in the reacting cylinder body of electric furnace in the bottom, under vacuum and heating, makes the gallic acid fusing and plays decarboxylic reaction.Because pyrogallic acid melting temperature and evaporating temperature that reaction produces all are lower than the decarboxylic reaction temperature, so the fusing shape pyrogallic acid that produces evaporates gasification immediately, the pyrogallic acid of gasification goes condenser to condense on the inwall of condenser.Because the powder shape raw material thermal conductivity of electrically heated non-uniform temperature and accumulation is very poor, the unavoidable hot-spot of congee appearance shape reactant mixture that forms at reactor bottom and produce side reaction, at a large amount of burnt shape refuse of reactor bottom generation, recovery rate only about 50%.Pyrogallic acid gas condenses on the condenser inwall, and the work that gets into the pyrogallic acid on the artificial shovel lower wall in the condenser is very arduous and very unhygienic, very not hommization of production operation.
Summary of the invention
The present invention seeks to provides a kind of continous vacuum reactive evaporation machine that condenses for pyrogallic acid production; The evaporation of decarboxylic reaction and pyrogallic acid is respectively in two kinds of different temperatures, the different time of staying with under the uniform thin layer condition of temperature, carry out; Evaporate the pyrogallic acid gas that and advance in the machine with fixed attention with dynamic to put the pyrogallic acid powder body that in the machine that condenses quality meets the pyrogallic acid product standard through giving of cooling and contact, hot pyrogallic acid gas is condensed on the cold powder body.
Technical scheme of the present invention is: the continous vacuum reactive evaporation machine that condenses is connected to form through the pyrogallic acid outlet by vertical response rapid steamer and the horizontal machine two parts that condense; The reactive evaporation machine is the vertical cylindrical shell of bullet for the ellipsoidal head bottom by the top of band heat-conducting oil heating chuck; In vertical cylindrical shell, establish polylith heat-conducting oil heating square position; Each heats the square position and establishes independent conduction oil import and export; All establish flat mouthful an of discharging on the every square position, the flat mouth of discharging has deflector, the position of the leading discharge port of directed flow direction of flow; Installing hole is established at each center, square position; The concentric bispin rotating shaft of two kinds of different rotating speeds is located at the center of cylindrical shell; The inward turning shaft support of bispin rotating shaft is on the cover plate for manhole of cylindrical shell bottom with one heart, and the fastening material supporting arm of scraping in the inside and outside rotating shaft both sides of bispin rotating shaft, scraper plate are fastened on to be scraped on the material supporting arm; Scraper plate in the outward turning rotating shaft is specially scraped the product on the decarboxylic reaction square position, and the scraper plate on the interior rotating shaft is specially scraped pyrogallic acid molten thing; Solid material is added on the lastblock square position, reacts secondary output object and is discharged into the cone from next piece square position, all establishes vacuum seal between the outer shaft of bispin rotating shaft and interior axle and outer shaft and the cylindrical shell; In the machine that condenses, establish the flight sub-assembly that is combined into by polylith flight and flight driving shaft etc.; In the gallic acid gas outlet tube of flight rotating shaft one end bearing in stretching into the reactive evaporation machine; Driving machine drives the sprocket wheel on the flight rotating shaft; Promote the flight sub-assembly and rotate to a direction, the pyrogallic acid powder body of in rotation, taking up pre-cooled, continuation is spilt cold powder body on the pyrogallic acid gas passage of thermotropism again; So gallic acid gas condenses on the powder body, incoagulability tail gas is extracted out through vacuum pumping opening; Spray pipe is established at the horizontal machine drum body top of condensing, and cooling water collects in the bosh and discharges through coolant outlet.
The continous vacuum reactive evaporation condense machine be by the reaction and the evaporation the different temperatures needs; Be respectively reaction and evaporate required suitable conduction oil temperature is provided; Be aided with thin layer heating on reaction and the evaporation square position again and by time of staying of scraper plate rotating speed control; Avoid reaction and evaporation material to meet with hot-spot; For reducing side reaction and improving recovery rate and create conditions, condense machine more product condense on the qualified homogeneous product of flow dispersion, extremely conveniently discharge product and thoroughly solve problem user-friendly for operation.
