Description
Technical field
This utility model relates to Petroleum refining equipment technical field, is specifically related to a kind of refinery gas fractionating device.
Background technology
Fractional distillation is a kind of method of the mixture of the volatile material separating several different boiling；A certain mixture is carried out
Heating, the different boiling for composition each in mixture carries out the one matter process that refrigerated separation becomes relatively pure.During
Do not have novel substance to generate, simply the starting substance is separated, belong to physical change.Fractional distillation is actually repeatedly distilled, and it is suitableeer
The liquid organic mixture being more or less the same together in separating-purifying boiling point.Fractional distillation such as coal tar；The fractional distillation of oil.Boiling when material
When point is sufficiently close to, about difference 20 degree, then cannot use simple distllation, can use fractionating process instead.The pillar of dephlegmator can provide
One high surface area gives devaporation.
But traditional fractionating device is fairly simple, being merely able to carry out single fractional distillation, work efficiency is relatively low.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of reasonable in design, structure letter
Single refinery gas's fractionating device.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this one refinery gas fractionating device,
It comprises heating crude oil storage tank, gas fractionation connecting tube, condensing unit, collection mouth, arc connecting tube, plugging valve, waste material receipts
Collection storage tank；The upper end of described heating crude oil storage tank connects several gas fractionation connecting tube；Adjacent gas fractionation connecting tube
Between be provided with condensing unit, the inner side of condensing unit connects collection mouth；Outside described adjacent gas fractionation connecting tube
Side connects has arc connecting tube, the entrance point of arc connecting tube to be provided with plugging valve；The gas fractionation connecting tube of low order end is even
It is connected to garbage collection storage tank.
In above-mentioned a kind of refinery gas fractionating device, the spiral that is internally provided with of described condensing unit condenses
Pipe, spiral cold-finger one end is connected with air inlet, and the other end is connected with collection mouth；And the inside of condensing unit be filled with circulation cold
But liquid.
In above-mentioned a kind of refinery gas fractionating device, between described gas fractionation connecting tube and condensing unit all
Employing is tightly connected.
Compared with prior art, the beneficial effects of the utility model are: its simple in construction, novel in design, it is possible to according to former
Different material boiling point at different temperatures in oil, head is collected in only switching condensation；With ensure each other will not cross-contamination,
More convenient and practical.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is this utility model condensing unit structural representation.
Description of reference numerals: heating crude oil storage tank 1, gas fractionation connecting tube 2, condensing unit 3, collection mouth 4, arc connect
Pipe 5, plugging valve 6, garbage collection storage tank 7, spiral cold-finger 8, circulating cooling liquid 9, air inlet 10.
Detailed description of the invention:
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figure 1 and Figure 2, this detailed description of the invention adopts the following technical scheme that it comprises heating crude oil storage tank 1, gas
Fractional distillation connecting tube 2, condensing unit 3, collection mouth 4, arc connecting tube 5, plugging valve 6, garbage collection storage tank 7；Described crude oil
The upper end connection adding hot tank 1 has several gas fractionation connecting tube 2；It is provided with condensation between adjacent gas fractionation connecting tube 2
Device 3, the inner side of condensing unit 3 connects collection mouth 4；The outside of described adjacent gas fractionation connecting tube 2 connects arc
Shape connecting tube 5, the entrance point of arc connecting tube 5 is provided with plugging valve 6；Gas fractionation connecting tube 2 connection of low order end has useless
Storage tank 7 collected by material.
In above-mentioned a kind of refinery gas fractionating device, the spiral that is internally provided with of described condensing unit 3 condenses
Pipe 8, spiral cold-finger 8 one end is connected with air inlet 10, and the other end is connected with collection mouth 4；And the inside of condensing unit 3 is filled with
Circulating cooling liquid 9.
In above-mentioned a kind of refinery gas fractionating device, between described gas fractionation connecting tube 2 and condensing unit 3
All use and be tightly connected.
The operation principle of this detailed description of the invention is: first passes through heater and carries out controlled to heating crude oil storage tank 1
Heated at constant temperature, in crude oil, different material gasifies at different temperatures, is then carried out with coordinating of collection mouth 4 by condensing unit 3
Collect, then regulate the steady temperature of heater；Open first plugging valve 6, by second group of condensing unit 3 and collection
The cooperation of mouth 4 carries out the condensation of the second material and collects operation；By that analogy.
Although this utility model being described in detail with reference to previous embodiment, those skilled in the art is come
Saying, the technical scheme described in foregoing embodiments still can be modified by it, or enters wherein portion of techniques feature
Row equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all should
