Description

Novel bromine dropwise adding device

Technical Field

The utility model relates to a dropwise add device, concretely relates to bromine dropwise add device belongs to the chemical industry equipment field.

Background

Bromine is an important chemical raw material and is widely applied to the fields of medicines, pesticides, dyes, spices and the like, which relate to organic synthesis. Is mainly used for preparing bromide in the field of organic synthesis, and is usually required to be added dropwise. However, unlike common organic materials, bromine is a highly toxic, corrosive and dangerous chemical, which puts high demands on both operator quality and equipment reliability, and may cause serious accidents with little carelessness during operation. The traditional method is to add bromine into a head tank for dripping by the action of gravity, but the method is very dangerous, and is basically eliminated because the equipment failure rate is very high due to the strong corrosivity of the bromine. The existing documents and patents report a plurality of new methods, one is that a bromine elevated tank is pressurized by an external air source, and then is automatically dripped by the siphonage, so that the danger caused by leakage at the bottom of the elevated tank is avoided, but the material flushing or explosion is easy to occur in the pressing process, and the potential safety hazard is also existed; the other type is that complex and expensive equipment is adopted to dropwise add bromine, although the reliability is high, the equipment maintenance cost is high, the early investment is large, the economy is high, and the production of small and medium-sized chemical enterprises is not facilitated.

Disclosure of Invention

Aiming at the problems in the background technology, the utility model provides an improved scheme, which adopts a special device to replace a nitrogen pressurization or air pressurization mode to ensure that bromine obtains siphon kinetic energy and then automatically drips; in order to realize the technical purpose, reach the expectancy effect, the utility model discloses a following technical scheme realizes.

The utility model provides a bromine dropwise add device, includes bromine dropwise add jar, bromine dropwise add pipe and bromine reactor, bromine dropwise add jar gag have the diplopore rubber buffer, diplopore rubber buffer one end even have the gassing tube valve with the air intercommunication, the other end even has bromine dropwise add pipe, bromine dropwise add pipe one end even have tremble formula extractor, the bromine reactor is connected to the other end.

Furthermore, the bromine dropping pipe is made of polytetrafluoroethylene or polyvinylidene fluoride.

Furthermore, the two small balls in the shaking extractor connected with the bromine dropping pipe are made of glass.

Advantageous effects

1. The shaking extractor is adopted to firstly pump bromine into the reactor, and then siphon dripping is utilized, so that the danger caused by pressurization by an external gas source is avoided.

2. Because the bottom of the elevated tank is not provided with an opening, the possibility of bromine leakage is avoided. The device has the advantages of simple structure, convenient maintenance, quicker operation and higher safety, and is very suitable for the small and medium-scale bromine dripping production and application.

Of course, it is not necessary for any product of the present invention to achieve all of the above simultaneously

Has the advantages of simple process and low cost.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural diagram of the bromine dripping device of the present invention, and the component list represented by each symbol in the drawing is as follows: 1-a gas release pipe valve, 2-a double-hole rubber plug, a 3-bromine dripping tank, a 4-bromine dripping pipe, a 5-ball valve, a 6-ball valve, a 7-bromine reactor, an 8-shaking extractor, a 9-glass ball and a 10-glass ball.

Detailed Description

The first embodiment is as follows: as shown in fig. 1, a novel bromine dripping device comprises: 1-a gas release pipe valve, 2-a double-hole rubber plug, a 3-bromine dripping tank, a 4-bromine dripping pipe, a 5-ball valve, a 6-ball valve, a 7-bromine reactor, an 8-shaking extractor, a 9-glass ball, a 10-glass ball and the like.

The bromine dripping tank is connected with a rubber plug, the rubber plug is connected with an air release pipe valve and a dripping pipe which are communicated with air, the lower end of the dripping pipe is connected with a shaking type extractor, and the other end of the dripping pipe is connected with a bromine reactor.

Wherein, the dropping pipe is connected with two ball valves.

The bromine dropping pipe is made of polytetrafluoroethylene or polyvinylidene fluoride.

Wherein, the two small balls in the shaking extractor connected with the bromine dropping pipe are made of glass.

A concrete application of this embodiment is, extract diplopore rubber buffer 2, open valve 1, open valve 5, open valve 6, shake the dropping pipe 4 times until bromine flows into bromine reactor 7 through the dropping pipe, plug diplopore rubber buffer 2 into bromine dropwise add jar 3, through siphon dropping bromine, through valve 5 and the control dropping speed of valve 6.
