Background technique
The preparation key reaction of biodiesel is carried out in esterifier, and the judgement of reaction end is according to reaction
Depending on the acid value of liquid, the definition of acid value refers to potassium hydroxide required for the free fatty acid for neutralizing and containing in 1 gram of sample
Milligram number, the accuracy of acid value measuring directly affect the progress of reaction, the quality of product.General obtained by sampler
Accurate sample is sent to laboratory, measures acid value using manual titration's either machine titration.
Since the raw material oil quality for producing biodiesel is unstable, so biodiesel is in continuous production process,
Its acidity is continually changing, so needing frequently to detect it.The biodiesel produced flows master in the duct
If laminar flow, laminar flow is a kind of flow regime of fluid, it makees the flowing of stratiform.Its particle is made along the direction parallel with pipe axis
Smooth linear motion.The flow velocity of fluid is maximum at tube hub, minimum at nearly wall.It is new close to the biodiesel of tube hub
Production, closer to the biodiesel of tube wall it is more long before produce, result in biological bavin everywhere in pipeline section
Oil is not quite similar.
Present biodiesel detector is general, and only certain samples in pipeline, can not obtain in pipeline biological bavin everywhere
The information of oil, error is larger, affects the quality of biodiesel.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, propose a kind of acid number of biodiesel on-line checking device,
It is not comprehensive to solve the sampling of the biodiesel detector as caused by laminar flow in the prior art, leads to the biggish skill of experimental results error
Art problem.
In order to reach above-mentioned technical purpose, the utility model embodiment provides a kind of acid number of biodiesel on-line checking
Device, the acid number of biodiesel on-line checking device include:
Titrate room comprising neutralizing tank, material-pumping tube and buret neutralize and offer observation window on pot sidewall, and bottom is opened
Equipped with drain hole, material-pumping tube upper end is connected to neutralizing tank, and biodiesel delivery pipe is run through in lower end, and material-pumping tube is located at biological oil-producing conveying
Part in pipe is uniformly provided with multiple feed openings, and buret is connected to neutralizing tank；
Vacuum pump is connected to neutralizing tank；
Soda acid detector, test side are inserted into neutralizing tank.
Compared with prior art, the utility model has the following beneficial effects: the acid number of biodiesel of the utility model exists
Biodiesel delivery pipe is run through in the material-pumping tube lower end of thread detector, and is uniformly provided with multiple feed openings, can comprehensively take out
Biodiesel everywhere in pipeline is taken, so that measurement result is more nearly the actual conditions in pipeline, reduces error, promotes biology
The production quality of diesel oil.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of acid number of biodiesel on-line checking device provided by the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Referring to Figure 1, Fig. 1 is the structural schematic diagram of acid number of biodiesel on-line checking device provided by the utility model.
Acid number of biodiesel on-line checking device includes: titration room, vacuum pump 2 and soda acid detector 3.
Titrating room includes neutralizing tank 11, material-pumping tube 12, buret 13 and support column 14.
In order to realize the function of on-line checking, titration room is arranged in biodiesel delivery pipe 4, at any time in extraction conduit
Biodiesel is detected.Neutralizing tank 11 is connect by support column 14 with biodiesel delivery pipe 4, and it is solid that support column 14 plays connection
Surely the effect supported offers a transparent observation window 111 on neutralizing tank 11, has one or more quarters on observation window 111
Line is spent, for facilitating operator to control the amount of the biodiesel in neutralizing tank 11, is allowed to the life extracted in detection each time
The amount of object diesel oil is all identical.The bottom of neutralizing tank 11 offers a drain hole 112, and experiment opens drain hole 112 after finishing,
Liquid for being vented in neutralizing tank 11.12 upper end of material-pumping tube is connected to the bottom of neutralizing tank 11, and it is defeated that lower end is inserted into biodiesel
It send in pipe 4, and passes through the axis of biodiesel delivery pipe 4, extend to the other side of biodiesel delivery pipe 4.In material-pumping tube
12 part between neutralizing tank 11 and biodiesel delivery pipe 4 is provided with valve.Material-pumping tube 12 is located at biological oil-producing conveying
Part in pipe 4 is uniformly provided with multiple feed openings 121, enable extract biodiesel delivery pipe 4 apart from axis it is each away from
From Bio-diesel Samples.Buret 13 is connected to the upper end of neutralizing tank 11, and the amount of lye, buret 13 is added dropwise in observation for convenience
It is designed to transparent configuration, and is provided with graduation mark on side wall, the side close to neutralizing tank 11 is provided with valve.
Vacuum pump 2 is connected to neutralizing tank 11, for will be pumped into negative pressure in neutralizing tank 11, by the life in biodiesel delivery pipe 4
