Background technology
Gas-liquid reactor and gas-liquid separator generally are two equipment that design respectively and arrange.When gas, fluid flow are all big, inferior separating effect often in the gas-liquid separator of smaller size smaller, entrained liquid is serious.
Hydrogen peroxide solution (hydrogen peroxide) production is used the reaction tower of oxidizing tower as oxygen in organic materials and the air and stream, only has the gas liquid reaction section, and the gas-liquid flow is all bigger during reaction, and reaction back gas-liquid separation effect is poor, and entrained liquid is serious, brings potential safety hazard to production; And many group U type bobbin carriage coolers or simple material distribution sieve plate only are set in the reaction tower, and the reaction oxidization-hydrogenation ratio is low, generally has only 90～93%.
Summary of the invention
The utility model technical problem to be solved is: to the deficiency of above-mentioned prior art, provide a kind of gas collection liquid reaction and the hydrogen peroxide solution of the tool gas-liquid separation section that is located away from one to produce oxidizing tower.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of hydrogen peroxide solution of tool gas-liquid separation section is produced oxidizing tower; Comprise gas liquid reaction mass transfer section; This gas liquid reaction mass transfer section comprises gas distribution tube, and the gas-liquid sieve plate that distributes again of tower bottom, and this gas-liquid sieve plate that distributes again is arranged on the gas distribution tube top; Be characterized in: said oxidizing tower also comprises the gas-liquid separation section, and this gas-liquid separation section is distributed in gas liquid reaction mass transfer section top, by isolating cap, several gas-liquid rise material pipe, demister, and downspout form; This isolating cap 4 is taper, and the bottom is fixed on the oxidizing tower inwall, and this gas-liquid rises the material pipe and evenly is arranged on the isolating cap, and this demister is arranged on the top that this gas-liquid rises the material pipe, and this demister lower end is connected with downspout.
Said demister lower end is connected to liquid collecting plate; This liquid collecting plate is obliquely installed and is fixed on the reaction tower inwall; This demister is connected with downspout through this liquid collecting plate; Can flow to downspout along liquid collecting plate after making the gas droplets entrained catch, and be back in the liquid phase of gas-liquid separation section by demister.
Said gas liquid reaction mass transfer section is provided with XPG gas-liquid mass transfer packing layer above gas-liquid distributes sieve plate again; Make and be in even distribution between reaction mass all the time; Improved the collision probability between reaction molecular; Shortened effective time of staying (more than 6 minutes) of material in the tower, improved oxidization-hydrogenation ratio, made oxidization-hydrogenation ratio reach 95～98%.
Said gas-liquid rises in the material pipe and is provided with deflector, has avoided each to rise the mutual disturbance after the interior gas-liquid material of material pipe goes out pipe, thereby has improved gas-liquid separation efficient greatly.
So, this hydrogen peroxide solution is produced the setting of oxidizing tower gas-liquid separation section, gas liquid reaction and the design of gas-liquid isolation integral, has saved the setting and the pipe arrangement of external separator; Gas-liquid separation efficient is improved greatly; Reduce oxidized tail gas and carried working solution phenomenon and oxidation liquid entrapped air phenomenon secretly; Both improved the security of producing; The working solution that make to separate again directly force feed to extraction tower, thereby province's deoxidation liquid groove, oxidation liquid pump is saved the long-time running of a large amount of oxidation liquid pumps and is used electric consumption.
