The specific embodiment
A kind of dirty alcohol distillation column as shown in Figure 1, heat exchanger a4, heating clamber a5, heating clamber b6, vaporization chamber a9, the vaporization chamber b10 heating clamber of dirty alcohol stoste outside tower a11, tower b16 enters tower a11, tower b16 with the form of alcohol steam after processing, and avoided the corrosion of salt pair tower.This alcohol distillation column adopts Double-Tower Structure, and tower a11 adopts Steam Heating; The Steam Heating that tower b16 can adopt tower a11 not utilize; The steam that heating clamber a5, heating clamber b6 do not utilize completely, then enter tower a11, tower b16 heats to tower; The waste water of tower b16 is drained and is advanced into heat exchanger a4 for giving dirty alcohol preheating, and the waste water of tower b16 is comprised of three parts: the one, and the alcohol steam waste water that condensation forms in tower b16; The 2nd, the steam condensate (SC) in heating clamber a5 and heating clamber b6; The 3rd, the alcohol steam waste water that condensation forms in tower a11.The alcohol steam of tower a11 output heats to the steam in tower b16 by heat exchanger b12 before entering moisture trap a13.
Between dirty alcohol feed pump 1 and heat exchanger a4, be provided with valve member a2, valve member b3, control respectively the charging of heating clamber a5 and heating clamber b6, heating clamber a5 and heating clamber b6 have liquid level gauge, by computer, control dirty alcohol and enter heating clamber a5 and heating clamber b6, dirty alcohol enters vaporization chamber a9 and vaporization chamber b10 after Steam Heating, the gaseous state alcohol of evaporation enters tower a11 and tower b16 from vaporization chamber, unevaporated dirty reflow of alcohol returns heating clamber a5 and heating clamber b6 reheats, and forms circulation between heating clamber and vaporization chamber.
Tower a11 alcohol steam out enters heat exchanger b12 heat exchange and enters moisture trap a13 after cooling and carry out gas-liquid separation, and alcohol steam enters condenser b21 condensation and reclaims; Liquid alcohol enters reflux pump a14, reclaims the wine seminal concentration at initial stage when defective, and alcohol liquid anhydrates again through the reflux pump a14 tower a11 that refluxes back; When moisture trap a13 stores fullly, unnecessary alcohol also can be by the reflux pump a14 tower a11 that refluxes back.When alcohol reaches requirement concentration, Shut-off fitting g29 opens valve member h30 and makes alcohol in reflux pump a14 enter cooler 15 condensations to obtain alcohol finished product.After steam in heat exchanger b12 absorption heating tower b16 heating chamber, flow back to tower b16 heating chamber.
Alcohol steam in tower b16 enters moisture trap b18 after condenser a17 condensation, reclaims when the initial stage, wine seminal concentration was defective, and alcohol liquid anhydrates again through the reflux pump b19 tower b16 that refluxes back; When moisture trap b18 stores fullly, unnecessary alcohol also can be by the reflux pump b19 tower b16 that refluxes back.When alcohol reaches requirement concentration, Shut-off fitting i31 makes the liquid alcohol in reflux pump b19 enter the cooling alcohol finished product that obtains of cooler 15.The isolated alcohol steam of moisture trap b18 is sucked condenser b21 condensation by vavuum pump 20, the alcohol liquid obtaining enters collecting tank 22 and is back to reflux pump b19 through pump 23, remaining waste gas is spirituosity hardly, by the exhaust outlet 24 discharge systems on collecting tank 22 tops.
In dirty alcohol, contain salt, dirty alcohol enters tower a11, tower b16 with the form of alcohol steam and has avoided the corrosion to tower a11, tower b16, feed pump 1, valve member a2, valve member b3, heat exchanger a4, heating clamber a5, heating clamber b6, salt discharge valve a7, salt discharge valve b8, vaporization chamber a9, vaporization chamber b10 and be all provided with titanium coating or adopt the processing of titanium material with the connecting line between upper-part and dirty Ethanol Exposure face, recovery tower miscellaneous part adopts 304 stainless steels processing.
The be heated bottom in chamber of heating clamber a5 and heating clamber b6 inside is respectively arranged with salt discharge valve a7 and salt discharge valve b8, evaporating the impurity such as remaining salt can drain from salt discharge valve a7 and salt discharge valve b8, play the effect of automated cleaning, be conducive to the work of continuation continuity, therefore played good antisepsis.
Tower a11 bottom is provided with steam trap 36, and steam trap 36 is automatic valves of a kind of draining resistance vapour, and the waste water that tower a11 can be produced is discharged to tower b16, and the waste water in tower a11 is comprised of the condensed water of dirty alcohol steam and the steam condensate (SC) in tower a11.
Use this equipment to reclaim the finished product alcohol concentration >=90%(V/V obtaining), treating capacity can reach 120 tons/24 hours.
The above-mentioned specific embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to product form and the style of the above-mentioned specific embodiment; anyly meet a kind of dirty alcohol distillation column of the claims in the present invention book and suitable variation or the modification that any person of an ordinary skill in the technical field does it, all should fall into scope of patent protection of the present invention.
