Abstract
An atomizer for extracting and purifying 2-sulfydryl benzothiazole by a solvent method is disclosed, and comprises an atomizer shell (8). An atomizer sprayer (6) is arranged at the top of the shell (8) and the sprayer (6) is provided with a methylbenzene feed inlet (5) and a 2-sulfydryl benzothiazole feed inlet (4). An oxygen content test port (3) is arranged in the upper part of the shell, a vacuumizing opening (2), a nitrogen filling opening (1) and an anti-explosion opening (7) are arranged on the side wall of the shell and a discharge hole (9) is arranged at the bottom of the shell (8). With adoption of the technical scheme, an extractant enters from a methylbenzene liquid inlet pipe and forms a circular film through a methylbenzene film-forming cavity and the substance to be extracted enters from a 2-sulfydryl benzothiazole liquid inlet pipe and forms a ring-like film through the 2-sulfydryl benzothiazole liquid film forming cavity. The two ring-like films are intersected at the communication part of the liquid film forming cavity in large contact area. The two liquids are mixed evenly and the mixed liquid atomized adequately in an atomizer enters the extraction kettle for extraction with high extraction rate.
Description
Technical field
The utility model belongs to the purification technique field of thiofide 2-mercapto benzothiazole, is specifically related to a kind of atomizer that is used for solvent extraction purification 2-mercapto benzothiazole.
Background technology
Thiofide 2-mercapto benzothiazole (MBT) is widely used a kind of universal promoter in the rubber industry, is the maximum product of at present domestic and international thiofide volume of production and marketing, also is simultaneously the primary raw material of producing other promoter.High-load MBT still produces the primary raw material of cephalosporin analog antibiotic medicine.But the MBT purity that high pressure is synthesized is low, contains plurality of impurities (being referred to as resin), can not directly use.Therefore, the refining purification process of MBT becomes a very important step in its production.The production method of present domestic rubber vulcanization accelerant MBT has two kinds: the one, and the soda acid WATER-WASHING METHOD; The 2nd, solvent extraction.The soda acid WATER-WASHING METHOD is present domestic the most frequently used process for refining and purifying, accounts for dominant position.This method will consume a large amount of strong acid, highly basic and water, produces product per ton and can produce the high concentration saliferous organic basic waste water more than 45 tons, the post processing difficulty.Solvent extraction is present more novel process for refining and purifying.Along with the increasing of environmental protection dynamics, refining purification technique of solvent extraction and non-aqueous technique more and more receive people's attention.The solvent that existing solvent method uses is main with toluene mainly.Shortcomings such as but this technology is the opened type manually-operated, and extractant evaporates in the air, has severe operational environment, and labour intensity is big.
The utility model content
The purpose of the utility model is to solve the above-mentioned technical problem that exists in the prior art, and a kind of atomizer that is used for thiofide 2-mercapto benzothiazole totally enclosed type production system is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following:
The atomizer that is used for solvent extraction purification 2-mercapto benzothiazole of the utility model; Comprise the atomizer housing, be provided with the atomizer shower nozzle in case top, housing top is provided with the oxygen content test port; Housing sidewall is provided with vacuum orifice, adds nitrogen mouth and venting, and housing bottom is provided with discharging opening.
Described atomizer shower nozzle comprises head body, is provided with the toluene feed tube that is communicated with the toluene feed mouth on head body top, and the toluene feed tube is communicated with the toluene film forming chamber; On the sidewall of head body, be provided with the 2-mercapto benzothiazole feed tube that is communicated with 2-mercapto benzothiazole charging aperture; 2-mercapto benzothiazole feed tube is communicated with 2-mercapto benzothiazole film forming chamber; Toluene liquid film forming chamber bottom is connected with 2-mercapto benzothiazole film forming chamber bottom, and the head body bottom is provided with mixture export.
Described toluene film forming chamber is cylindric.
Described 2-mercapto benzothiazole film forming chamber is cylindric.
Described toluene film forming chamber bottom is a conically shaped with the place of being connected, 2-mercapto benzothiazole film forming chamber bottom.
Owing to adopt technique scheme, extractant gets into through the toluene feed tube, forms the annular film through the toluene film forming chamber; Treat that extracting substance passes through 2-mercapto benzothiazole feed tube and gets into, form circular membrane through 2-mercapto benzothiazole film forming chamber, two circular membrane cross in connection place of liquid film forming chamber; Contact area is big; Two kinds of liquid mixing are even, and mixing material fully extracts through discharging opening entering extraction kettle after the atomizing in atomizer, and extraction yield is high.
