Only increase production energy consumption, also wastes the cooling capacity of deep cooling sulfur dioxide.Therefore, deep cooling sulfur dioxide how is made full use of
Cooling capacity, realize the energy-saving of production process, there is very big practicability and necessity.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of conversions of deep cooling sulfur dioxide cooling capacity to fill
It sets, it is scientific and reasonable, it is simple and easy, the cooling capacity of deep cooling sulfur dioxide can not only be made full use of, realizes the energy conservation drop of production process
Consumption, and improve the safety and stability of production.
Deep cooling sulfur dioxide cooling capacity reforming unit described in the utility model, including sulfur dioxide storage tank, condenser are gentle
Change pond；The sulfur dioxide storage tank is connected by circulation by the cold source medium channel of circulating pump and condenser；The sulfur dioxide storage
Tank is connected by gas phase discharging pipeline and liquid phase discharging pipeline with gasification pond respectively.
The sulfur dioxide storage tank is connected with feeding line, gas phase discharging pipeline and liquid phase discharging pipeline, and wherein gas phase goes out
Expects pipe line is equipped with pneumatic operated valve and pressure reducing valve, and liquid phase discharges pipeline equipped with discharging pump.
The condenser is connected with heat source medium inlet line, vapor delivery line and liquid phase pipeline, is used for acyl chlorides production process
The condensation split-phase of middle gaseous component.
The course of work of the utility model, comprising the following steps:
1) sulfur dioxide of -10 DEG C after deep cooling~-5 DEG C is passed through in sulfur dioxide storage tank by feeding line, then led to
The cold source medium channel that sulfur dioxide is passed through condenser by circulating pump is crossed, sulfur dioxide storage tank is back to after heat exchange；
2) heat source medium is passed through condenser by heat source medium inlet line, and after heat exchange condensation, on-condensible gas is passed through gas phase
Pipeline, condensed fluid are passed through liquid phase pipeline；
3) in sulfur dioxide storage tank, upper gas sulfur dioxide enters gasification pond, lower liquid two through gas phase discharging pipeline
Sulfur oxide enters gasification pond through liquid phase discharging pipeline, and the production of chlorosulfuric acid is sufficiently used for after gasification.
Compared with prior art, the utility model has the advantage that
The cold source medium channel of sulfur dioxide storage tank and condenser is connected by circulation by the utility model, passes through deep cooling titanium dioxide
The condensation of sulphur realizes the energy in the cooling capacity and acyl chlorides synthesis process of deep cooling sulfur dioxide between the heat of gaseous component
Conversion, preheated sulfur dioxide, reduce the later period gasification thermal energy consumption, while use deep cooling sulfur dioxide instead of chilled water as
The cold source medium of condenser, decreases the consumption of chilled water, keeps entire production process more energy saving, reduces and be produced into
This；In addition, reducing sulfur dioxide and vapor, water contact probability in production process, the safety of apparatus and process is improved, is reduced
Extent of injury when accident occurs, while can be energy-saving, realize heat conversion.
