Description
Technical field
The utility model belongs to tobacco processing equipment field, is specifically related to a kind of nicotine extraction tower.
Background technology
Containing multiple alkaloid in tobacco, what obtained qualification just has kind more than 40, and wherein maximum with nicotine content, account for 95% of nicotiana alkaloids, nicotine accounts for the 0.5-6% of tobacco dry weight.Nicotine all has a wide range of applications in field of medicaments and chemical field.Pharmacological research shows: nicotine can be combined with the nicotine cholinergic of periphery and central nervous system, multiple effect is had to brain, can multiple neurochemistry passage be activated, can cause improving awakening, notice and reactivity to the effect of nervous centralis, reduce anxiety and nervous reaction.Some pharmaceutically acceptable nicotine salt compound is effective in cure to some disease, as by nicotine tartrate local drug delivery, can treat the muscle cramp and arthralgia that can not alleviate with massage or aspirin.In addition nicotine sulphate is a kind of high-efficiency low-toxicity, and without the resistance to the action of a drug, noresidue, does not poison, the very potential vegetable insecticide of contaminated land, is " environment friendly agricultural ", for control cotton and vegetable aphid effect excellent.What generally adopt at present is in sulfuric acid and reextraction nicotine, in common container, add sulfuric acid and extract carry out artificial or machine and stirred extraction, when organic solvent exposure is to sulfuric acid, the impurity produced in whipping process, bubble and serious turbulent flow easily produce emulsion, cause percent defective high, and cannot consecutive production.Domestic not yet have good equipment efficiently to extract nicotine extract at present.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of nicotine extraction tower, its compact conformation, reasonable in design, eliminates the generation of emulsion, achieves consecutive production, improve economic benefit.
The technical solution of the utility model is achieved in that a kind of nicotine extraction tower, comprises tower body, and this tower body top is provided with solvent recovery pipe and escape pipe, and bottom is provided with extract inlet tube and sulfuric acid inlet tube; Probe tube is provided with in the middle part of described tower body; Described extract inlet tube is also connected with shower, and this shower top seal, tube wall has and organizes spray apertures more; Described extract inlet tube and sulfuric acid inlet tube are also connected to acid and alkali-proof pump.
Preferably, the length 100 ~ 180cm of described shower, the spray apertures diameter 5 ~ 8mm on this shower.
Preferably, described nicotine extraction tower tower body is cylindrical, and tower top is spherical in shape.
Preferably, described extract inlet tube and the nozzle diameter of sulfuric acid inlet tube are 50mm.
Preferably, described solvent recovery pipe, sulfuric acid inlet tube, extract inlet tube and probe tube are made up of PVC material.
The utility model solves the defect existed in background technology, and the utility model has beneficial effect and is:
The nicotine extraction tower that the utility model provides, adopt reflux type extraction nicotine, eliminate the generation of emulsion in stirring in conventional container, Simultaneous Stabilization is good, achieves continuous seepage, improves production efficiency; In addition product is convenient reclaims, and eliminates the energy consumption adopted needed for agitating mode, energy-efficient, easy suitability for industrialized production.
Accompanying drawing explanation
Fig. 1 is the structural representation of nicotine extraction tower;
Fig. 2 is the top view of Fig. 1 nicotine extraction tower;
In figure: 1-tower body, 2-escape pipe, 3-solvent recovery pipe, 4-probe tube, 5-extract inlet tube, 6-sulfuric acid inlet tube, 7-nicotine extract, 8-sulfuric acid solution, 9-acid and alkali-proof pump, 10-shower.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of nicotine extraction tower as depicted in figs. 1 and 2, comprises tower body 1, and this tower body 1 top is provided with solvent recovery pipe 3 and escape pipe 2, and bottom is provided with extract inlet tube 5 and sulfuric acid inlet tube 6; Probe tube 4 is provided with in the middle part of tower body 1; Extract inlet tube 5 is also connected with shower 10, and this shower top seal, tube wall has and organizes spray apertures more; Extract inlet tube 5 and sulfuric acid inlet tube 6 are also connected to acid and alkali-proof pump 9.Length 100 ~ the 180cm of shower, the spray apertures diameter 5 ~ 8mm on this shower.The length 150cm of shower 10 in the present embodiment, spray apertures diameter 7mm, shower 10 diameter is 55mm.Spray apertures diameter is less than 5mm, and spray rate is excessively slow, increases the production time; Spray apertures diameter is greater than 8mm, then jet speed is excessive, can cause locally emulsification occurring.Nicotine extraction tower tower body 1 is cylindrical, and tower top is spherical in shape, tower height 6 meters.The nozzle diameter of extract inlet tube 5 and sulfuric acid inlet tube 6 is 50mm.Solvent recovery pipe 3, sulfuric acid inlet tube 6, extract inlet tube 5 and probe tube 4 are made up of PVC material.PVC has low flammability, high strength, resistance to climate variability and excellent geometrical stability.In addition PVC has very strong resistance to oxidant, reducing agent and strong acid, is highly suitable for the manufactured materials of the pipeline of this extraction tower.
Utility model works principle is: this nicotine extraction tower adopts reflux type extraction nicotine, according to sulfuric acid and extract proportion characteristic, heavy sulfuric acid extractant is as static phase, and the little organic extract liquid of proportion is as mobile phase, extract slowly upwards penetrates sulfuric acid solution from tower body 1 bottom adverse current and completes extraction overall process.
The course of work of the present utility model is: first open sulfuric acid inlet tube 6, start the acid and alkali-proof pump 9 be attached thereto, the full sulfuric acid liquid 8 of pump in the cylindrical shell 1 of nicotine extraction tower, then extract inlet tube 5 is opened, start the acid and alkali-proof pump 9 be attached thereto, in nicotine extraction tower cylindrical shell 1, pump into the nicotine extract 7 being mixed with normal hexane from storage tank.Extract is by shower 10, and due to shower 10 top seal, extract is radial direction evenly ejection from the spray apertures tube wall to surrounding, and direct axially the ejection upward of traditional liquid is compared, and hydraulic shock power reduces a lot, and nicotine extract diffusion effect is good.When nicotine extract 7 sprays from shower 10, upwards can permeate uniformly, through the sulfuric acid solution 8 of 6 meters high, carry out extractive reaction.Last can reaching neutralizes completely, excellent.Nicotine extract 7 enters from lower end toward upper end continuously, evenly penetrates sulfuric acid liquid, automatically overflows and reclaims from solvent recovery pipe 3 outflow, namely obtain the product of nicotine sulphate when finally arriving tower body 1 top.Nicotine extraction tower height 6 meters, normal extraction time 12-18 hour, terminates until pH value reaches 6-6.5 extraction.Can carry out the tracing detection pH value of overall process in operating process, operating personnel can carry out pH value detection from probe tube 4 sampling, easy to operate.Adopt this nicotine extraction tower, be easy to aqueous phase to be separated with organic layer, avoid the generation of emulsification, also achieve efficient and continuous prodution simultaneously, improve the productivity ratio of nicotine extraction.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
