Description
Technical field
The utility model relates to the device that improves the gas reactant temperature in a kind of sulfur oxychloride preparation, belongs to the chemical industry equipment field.
Background technology
Sulfur oxychloride is a kind of important organic synthesis chlorizating agent, such as the chlorine displacement of chlorination, organic sulfonic acid or the nitro-compound of the chlorination of the chlorination of alcohols hydroxyl, carboxylic acid, acid anhydrides.Make acyl chloride, can also be used for ring-closure reaction and beckmann rearrangement.(select from " inorganic chemicals industry handbook second edition, P601 compiles in Tianjin chemical research institute)
The synthetic method of the sulfur oxychloride of suitable suitability for industrialized production commonly used has three kinds:
⑴ sulphur trioxide method: the reaction of phosphorus pentachloride and sulphur trioxide, generate sulfur oxychloride and phosphorus oxychloride, this route technique is simple, but because sulfur oxychloride and phosphorus oxychloride separating difficulty are large, product is not easy to purify.
⑵ chlorosulfonic acid method: take antimony chloride etc. as catalyzer, make sulfur monochloride and chlorine, chlorsulfonic acid reaction, this method complex process, backward in technique, material consumption is large, and is seriously polluted.
⑶ sulfurous gas method: advanced operational path, chlorine, sulfur dichloride and sulfurous gas under the condition of activated carbon catalyst, the generation sulfur oxychloride that reacts, this technique is simple, less investment, product purity are high, at present this technique of domestic most employing.
The sulfur oxychloride synthesis reactor is a shell and tube fixation reaction bed, and tube side is equipped with the catalyst activity charcoal, and shell side is equipped with thermal oil, and the sulfur oxychloride building-up reactions is carried out under 180-300 ℃, is a reversible thermopositive reaction, and Heat of Formation is-197.48KJ/mol.Along with the carrying out of reaction, the temperature of reaction mass can improve gradually, utilizes natural circulation or the pump circulation of thermal oil, guarantees that temperature is even up and down in the fixed-bed reactor.From reactor crude product sulfur oxychloride temperature out about 250-300 ℃, in the existing published technology there are no the report that utilizes this part waste heat.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: the device that improves the gas reactant temperature in a kind of sulfur oxychloride preparation is provided, utilizes the waste heat of crude product sulfur oxychloride, the heated air reactant, realize heat recovery, reduce reaction cost.
The technical scheme that its technical problem that solves the utility model adopts is: the device that improves the gas reactant temperature in a kind of sulfur oxychloride preparation is provided, it is characterized in that comprising: interchanger and shell and tube fixation reaction bed, heat exchanger tube pass is by the gas inlet of pipeline connection shell and tube fixation reaction bed upper end, and the material outlet of shell and tube fixation reaction bed lower end connects the heat exchanger shell pass import by pipeline.
Described heat exchanger shell pass outlet connects sulfur oxychloride crude product storage tank by pipeline.
Chlorine after the vaporization enters the sulfur dichloride synthesis reactor after metering, the sulfur monochloride that comes from the weight-removing column tower reactor also flows into the sulfur dichloride synthesis reactor after measuring, chlorine and sulfur monochloride react under 70 ℃-92 ℃ in the ratio of 150:0.25 (liquid), generate sulfur dichloride.The sulfurous gas temperature of coming from vaporizer is about 20-45 ℃, be the ratio mixing of 150:100:0.25 in Cl2:SO2:S2Cl2 with above-mentioned material after metering, temperature is about 50 ℃-90 ℃ after mixing, enter shell and tube heat exchanger of the present invention, carry out heat exchange with the crude product that from the next temperature of sulfur oxychloride synthesis reactor is 250 ℃-300 ℃, temperature is increased to 80 ℃ of-180 ℃ of laggard synthesis reactors, be 180 ℃-300 ℃ in temperature of reaction, pressure is to generate the sulfur oxychloride crude product under the 0.10MPa-0.25MPa.
The beneficial effects of the utility model are: by reactor crude product sulfur oxychloride temperature out, come the gas of reacting by heating, realized like this utilization of product waste heat, realized the recycle of energy, reduce reaction cost, improved product competitiveness, this device structure is simple simultaneously, is convenient to care and maintenance.
