Abstract

The utility model relates to a biodiesel pipe reactor, which is formed by connecting a support with a plurality of reaction segments, wherein a plurality of reaction segments are arranged on the support, and a plurality of reaction segments are connected by 180 degrees of elbows. The reaction segments are composed of a plurality of static mixing units, inner pipes and jackets. A plurality of static mixing units are arranged in the inner pipes, and the jackets are sheathed out the inner pipes. Two ends of the jackets are in welding connection with the inner pipes, and the jackets are connected by jacket communicating pipes. The static mixing unit in the first reaction segment of a plurality of reaction segments is an SX type static mixing unit, and the static mixing units in other first reaction segments are SL type static mixing unit. In the reaction segments, the outlet of every five to seven reaction segments from the first reaction segment is provided with a temperature measurement opening, a pressure measurement opening and a sampling opening. Compared with the tank reactor used for biodiesel at present, the biodiesel pipe reactor has the advantages of low energy consumption, continuous production and easy control in the production process.

Description

A kind of biodiesel pipeline reactor

Affiliated technical field

The utility model relates to the reactor that uses in the Chemical Manufacture, particularly relates to a kind of pipeline reactor of making biodiesel.

Technical background

Biodiesel is the new product that the alternative oil that is developed at energy shortage recent years is made diesel oil, used reactor is a tank reactor in the manufacturing of production biodiesel, its weak point is that the mixing in the reaction mass is stirred with the agitator in the motor drives still and mixed, it is bigger to consume energy, exist the dead angle to mix inhomogeneous in the stirring and cause reaction not thorough, make the yield of biodiesel lower, aborning can not serialization production.

The utility model content

The purpose of this utility model is to overcome the weak point of using reactor to produce in the present production of biodiesel, provide a kind of use static mixer hybrid energy dissipation little, can be continuously produced, in process of production a kind of biodiesel pipeline reactor of the easy control of technology.

The purpose of this utility model is achieved through the following technical solutions, and the biodiesel pipeline reactor is linked by support and a plurality of conversion zone and forms, and a plurality of conversion zones are contained on the support, link with 180 ° of elbows between a plurality of conversion zones.Conversion zone is made up of a plurality of static mixing unit, interior pipe and chuck, and in the pipe, outside the pipe, the two ends of chuck connected with interior pipe welding, link with the chuck cross over pipe between chuck in chuck was enclosed within a plurality of static mixing unit was contained in.Static mixing unit in a plurality of conversion zones in first conversion zone is SX type static mixing unit, static mixing unit in the remaining reaction section is SL type static mixing unit, is provided with temperature-measuring port, pressure tap and sample tap every the exit of 5-7 conversion zone in a plurality of conversion zones.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the left view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing: in the accompanying drawing 1---flange; 2---interior pipe; 3---SX type static mixing unit; 4---chuck; 5---support; 6---180 ° of elbows; 7---the chuck cross over pipe; 8---SL type static mixer unit; 9---retainer ring; N1---reacting material inlet; N2---reaction mass (biodiesel) outlet; N3---heat transferring medium import; N4---heat transferring medium outlet; N5---sample tap.

During enforcement, interior pipe 2 can be made with tubing, SX type static mixing unit 3 and SL type static mixing unit 8 can be made by Machinery Ministry proposed standard JB/T7660, gap during manufacturing between static mixing unit and interior pipe is suitable littler, help mixing of reaction mass, the also available tubing of chuck 4 is made, the internal diameter of chuck 4 should be than the external diameter of interior pipe 2 big 20～25mm, the heat exchange of pipe 2 internal reaction materials in helping like this, the two ends of chuck 4 be the end socket in hole in the middle of can be made into, and the aperture of this interstitial hole is bigger slightly than the external diameter of interior pipe 2, after the cylindrical section of end of end socket with holes and chuck is welded, behind the outside of pipe 2, interior pipe 2 and chuck 4 are welded into one in being enclosed within.Working condition of the present utility model is, reaction mass entered from N1, and be the classification of the endothermic reaction or exothermic reaction according to the reaction of reaction mass, in N3, feed heating agent or refrigerant.Flow out from N4 after between chuck 4 and internal diameter, flowing.Internally the reaction mass in the pipe 2 carries out heat exchange, and pipe 2 internal reaction storerooms reacts to each other in helping.Its conversion zone is with several sections, and the difference of visual reaction mass is tested after Chemical Engineering Calculation again and determined, and is after the sampling of sample tap reaches the index of biodiesel, so far.The utility model can constantly be imported reaction mass aborning from reacting material inlet N1, be allowed to condition at and constantly carry out hybrid reaction in the utility model, constantly produces biodiesel, can realize serialization production.
