Description
Technical field
The utility model is related to field of mechanical technique, and in particular to CO 2 purification system.
Background technology
Carbon dioxide is the main by-product generated in Alcohol Production fermentation process, often produces 1 ton of alcohol and theoretically may be used
About 0.96 ton of carbon dioxide is obtained, the concentration of carbon dioxide is higher in alcoholic fermentation gas, can reach 95% or more, and impurity is
Alcohols, aldehydes, esters and trace oxygen are conducive to the food-grade carbon-dioxide of production high-purity.To produce the wine of 100,000 tons of alcohol per year
For smart factory, production process can generate 90,000 tons of carbon dioxide year.The direct emission of carbon dioxide not only endangers environment, in fact
It is also a kind of wasting of resources.If this partial CO 2 can be recycled, greenhouse gas either is reduced to environmental protection
The discharge of body, or be all meaningful to the benefit of enterprise.
Carbon dioxide recovery technology during wine brewing, is generally used.
It generally comprises：Sequentially connected gas pretreatment unit, compression unit, purge drying unit, refrigeration condensing units,
Storage element, vaporization purifier units and the electronic control unit etc. for controlling said units work.
The carbon dioxide purification tower in purifier units is vaporized, is the important equipment of purifying carbon dioxide, more directly
The purity for determining carbon dioxide.
And the gas supply stability of carbon dioxide purification tower, then it is the working performance for determining equipment.Existing dioxy
Change the gas supply stability of carbon purification tower, there is also deficiencies.
Utility model content
The purpose of the utility model is to provide carbon dioxide recovery back pressure decompressors, solve above at least one skill
Art problem.
Following technical scheme may be used to realize in the technical issues of the utility model is solved：
Carbon dioxide recovery back pressure decompressor, it is characterised in that：Including a decompressor shell, outside the decompressor
Shell, one end are provided with the air inlet with air source unicom, and the other end is provided with the gas outlet with carbon dioxide purification tower unicom；
A back pressure pressure reducing valve is equipped in the decompressor shell；
The inlet end of the back pressure pressure reducing valve connects the air inlet, and the outlet side of the back pressure pressure reducing valve passes through a metal
Pipe connects the gas outlet；
It further include an electric heating system；
The electric heating system is provided with a power supply and a carbon fiber heating film, the power supply and the carbon fiber heating film
Between, by a pressure more than the pressure switch system unicom connected after threshold value；
The pressure switch system includes a switching circuit and a pressure sensor, and the pressure sensor is arranged described
In metal tube；
The metal tube outsourcing is equipped with carbon fiber heating film.
High pressure gas, after back pressure pressure reducing valve, gas pressure reduces, and volume expansion, temperature reduces rapidly, or even knot
Ice.
With the gas outlet of carbon dioxide purification tower unicom at freeze (dry ice or other organic gas ice), be common
Imaging.The stability of gas supply is seriously affected.
In this patent, the outlet side of back pressure pressure reducing valve is not allowed to be directly connected to carbon dioxide purification tower, but in
Between set up a metal tube, and provide pressure beyond the carbon fiber heating film for connecting heating after threshold value, heated for metal tube.
When because of freezing, and hindering outlet, the pressure in metal tube rises naturally, when the rising of pressure exceeds threshold value,
Natural driving pressure switching system powers on, and provides heating, and the tied ice (dry ice or other organic gas ice) of fusion makes gas
It flows smooth.Ensure equipment performance.
The metal tube is length in 20cm~30cm, and wall thickness is the White Copper Tubes of 2mm~4mm.Ensure anti-pressure ability, heat conduction
Ability is easy to the characteristics such as heating.
