Fraction it is cooling in condenser pipe after form liquid again after, taken over and flow in receiving bottle by tail.
In existing list fraction distillation process, vaporish fraction condensation rate is slow, and since the pressure of steam acts on,
The condensation of fraction is formed under high pressure, causes fraction impure.
Utility model content
The purpose of this utility model is to provide a kind of constant pressure addition for distillation for the deficiency in above-mentioned background technology
Pipe, to solve in the prior art, fraction condensation rate technical problem impure slowly and after fraction condensation.
To achieve the above object, the utility model uses the following technical solution：
For the constant pressure addition pipe of distillation, the constant pressure addition pipe includes pipe main body, and condensation is provided in the pipe main body
Net, the pipe main body upper and lower ends mouth are opening, and the upper end has detachable plug, and lower end is provided with controlled valve；Institute
The branch pipe for being additionally provided on the outer wall of pipe main body and being flowed for steam is stated, the branch pipe and the upper end junction of the pipe main body are located at
On the pipe main body inner condensat liquid net, the branch pipe and the lower end junction of the pipe main body are located under controlled valve, institute
It states branch pipe and converges the lower port for being connected to and constituting the pipe main body with the lower end of the pipe main body.
Compared with the prior art, the utility model has the advantages that：In the utility model, in constant pressure addition pipe master
It is horizontally disposed in vivo to have condensation net, by condensing contact of the net with steam, accelerates the condensation of steam, improve the condensation speed of fraction
Degree；Also, due to being additionally provided with the branch pipe flowed for steam, the upper end junction position of branch pipe and pipe main body on the outer wall of pipe main body
On pipe main body inner condensat liquid net, branch pipe and the lower end junction of pipe main body are located under controlled valve, so when in use,
Steam flowing is existed simultaneously in pipe main body and branch pipe, and is interconnected, and is realized constant pressure distillation, be ensure that the purity of fraction.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram that net is condensed in the utility model.
Specific implementation mode
The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.
As shown in Figure 1 and Figure 2, as a kind of preferred embodiment of the utility model, the utility model proposes one kind to be used for
The constant pressure addition pipe of distillation, the constant pressure addition pipe include pipe main body 10, and being horizontally disposed in the pipe main body 10 has condensation net 11,
10 upper and lower ends mouth of the pipe main body is opening, and the upper end has detachable plug 12, and lower end is provided with controlled valve 13；
The branch pipe 14 flowed for steam, the upper end of the branch pipe 14 and the pipe main body 10 are additionally provided on the outer wall of the pipe main body 10
Junction is located on the pipe main body inner condensat liquid net 11, and the branch pipe 14 and the lower end junction of the pipe main body 10 are located at
Under controlled valve 13, the branch pipe 14 converges the lower port for being connected to and constituting the pipe main body 10 with the lower end of the pipe main body 10
15, and the lower port 15 is taper, the lower end of the pipe main body 10 is arranged to contract in the upside pipeline section close to controlled valve 13
Cervical part of esophagus, and level is communicated with outlet tube 16 in the necking segment, the outlet tube 16 is located under condensation net 11 and on outlet tube 16
Valve 17 is set；14 outside of branch pipe of the constant pressure addition pipe is provided with hot water casing 18, the lower section tool of the hot water casing 18
There are hot water inlet 181, top that there is hot water outlet 182, the purpose of setting hot water casing 18 is to be branch in distillation process
Pipe heat supply prevents fraction from occurring condensing to flow back into distillation container in branch pipe, reduces distillation efficiency.
In said program, there are several condensation holes 111, the condensation hole 111 penetrates the condensation on the condensation net 11
The opening of net 11, the condensation hole 111 is gradually reduced the condensation hole 111 to form that cross section is taper from top to bottom.
Said program is connect with the outlet of distillation container when in use, by the lower port 15, under heat effect, distillation
After fraction the upper end of the pipe main body 10 is flowed to by the branch pipe 14, since the upper port of pipe main body 10 has plug
12, fraction flows and CONTACT WITH FRICTION occurs with the condensation net 11 gradually downward, at this point, fraction is under the action of condensing hole 111,
Rapidly condensation forms the fraction of liquid, and is dropped in the bottom of the pipe main body 10, since the bottom of pipe main body 10 is provided with out
Closing valve 14, fraction can not flow back into distillation container, can be from when liquid level constantly increases, and reaches the height of outlet tube 16
Outlet tube 16 flows out, and completes distillation process.
In the utility model, there is condensation net by being horizontally disposed in constant pressure addition pipe main body, by condensing net and steam
