Abstract
An alkyl sulfonyl chloride reaction device with an external circulating heat exchanger comprises a reactor, a feed pump and an ultraviolet light generator, wherein an inlet of the feed pump is connected with the reactor. The reaction device further comprises the heat exchanger; a tee at an outlet of the material pump is connected with a circulating valve and a discharging valve; an outlet of the circulating valve is connected with an inlet of the heat exchanger; and an outlet of the heat exchanger is connected to the upper part of the reactor. Through the improvement on the prior art, the problems that the heat exchange area of a heat exchange pipe coil made of lead is limited, the product quality is not guaranteed, the manufacturing and the replacement are inconvenient, and the product is polluted by heavy metal are solved. The utility model has the characteristics of low investment and long service life of equipment.
Description
Technical field
The utility model relates to a kind of alkyl sulfonyl chloride production technical field, especially a kind of alkyl sulfonyl chloride production technical field with the outer circulation heat exchange.
Background technology
Alkyl sulfonyl chloride is a kind of light yellow or brown oily liquids.Alkyl sulfonyl chloride can be prevented blocking ammonium caking as fertilizer additive.Alkyl sulfonyl chloride is a kind of non-water-soluble oily liquids simultaneously, is the raw material of producing the leather synthetic fat liquor.Alkyl sulfonyl chloride is to be that 15 natural oil n-alkane is a raw material with average carbochain, carries out the methyl chloride acylation reaction with chlorine, sulfur dioxide and generates.This reaction is exothermic reaction, and the heat that produces in must will reacting is taken away with the mode of cooling.
At present the most frequently used method is as shown in Figure 1, and n-alkane generates alkyl sulfonyl chloride with a certain proportion of chlorine, sulfur dioxide reaction under the UV-irradiation that ultraviolet light generator 3 produces.Technological process is: n-alkane gets into after preliminary treatment in the reactor 1, feeds chlorine and sulfur dioxide, under the irradiation of ultraviolet light, carries out the methyl chloride acylation reaction, and cooling water is taken the reaction liberated heat out of through lead system heat exchange coil 2.Material was through 4 outputs of material pump after reaction was accomplished.Raw material chlorine, the sulfur dioxide of alkyl sulfonyl chloride production are the highly acid material, are reflected in the severe corrosive environment and carry out, and harsh to the material requirements of device, reactor commonly used is a polypropylene material.The temperature requirement of reaction is strict controlled in below 45 ℃.In order in time heat to be taken out of, heat-exchanger rig adopts the better and relative corrosion-resistant metallic lead material that conducts heat to process heat exchange coil.But there is following shortcoming in plumbous system heat exchange coil: 1, because space reactor is limited, and heat exchange area is restricted, reaction temperature can not get guaranteeing; 2, fabrication and installation coil pipe operating difficulties in reactor; 3, metallic lead is not good to the corrosion resistance of medium, needs to change once in general one to two year; 4, the lead that is corroded is sneaked in the product, causes heavy metal pollution.
The utility model content
The utility model purpose provides a kind of technical scheme, adopts external circulating device, and material is accomplished reaction in the cycle heat exchange outside, to overcome the shortcoming that exists in the above-mentioned prior art.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of alkyl sulfonyl chloride reaction unit of outer circulation heat exchange; Comprise reactor, material pump, ultraviolet light generator; The import of material pump is connected with reactor, it is characterized in that also comprising heat exchanger, and the threeway of material delivery side of pump is connected with circulation valve and discharging valve; The circulation valve outlet is connected with the import of heat exchanger, and the outlet of heat exchanger is connected to reactor top.
Usually heat exchanger adopts the enamel spiral heat exchanger.
The prior art that changed the utility model adopts the lead system heat exchange coil of cooling water in reactor to cool off; Adopt the outer circulation heat exchange of peripheral hardware heat exchanger; Reaction mass materials pump transported in the enamel spiral heat exchanger corrosion-resistant, that heat conduction good, heat exchange area can dispose arbitrarily cool off; Under design temperature control requires, accomplish reaction, obtain finished product.
The beneficial effect of the utility model is: the utility model passes through improvements over the prior art; The heat exchange area that has solved plumbous system heat exchange coil is restricted; And product quality can not get guaranteeing, make change inconvenient, cause problems such as product heavy metal pollution; Has small investment, the characteristics that service life of equipment is long.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
The process flow diagram of Fig. 1 prior art.
The process flow diagram of Fig. 2 the utility model embodiment.
Among the figure: 1, reactor 2, plumbous system heat exchange coil 3, ultraviolet light generator 4, material pump 5, enamel spiral heat exchanger 6, circulation valve 7, discharging valve 8, n-alkane import 9, chlorine and sulfur dioxide import.
The specific embodiment
Among Fig. 2; A kind of alkyl sulfonyl chloride reaction unit of outer circulation heat exchange; Comprise reactor 1, enamel spiral heat exchanger 5, material pump 4, ultraviolet light generator 3; Reactor 1 is provided with n-alkane import 8, chlorine and sulfur dioxide import 9, and the import of material pump 4 is connected with reactor 1, and the outlet threeway of material pump 4 is connected with circulation valve 6 and discharging valve 7; Circulation valve 6 outlets are connected with the import of enamel spiral heat exchanger 5, and the outlet of enamel spiral heat exchanger 5 is connected to reactor 1 top.
Among Fig. 2; Its technological process is: n-alkane gets in the reactor 1 after preliminary treatment; Close discharging valve 7, open material pump 4, enamel spiral heat exchanger 5 cooling waters and circulation valve 6, feed chlorine and sulfur dioxide; Under the irradiation of the ultraviolet light of ultraviolet light generator 3, carry out the methyl chloride acylation reaction, the reaction liberated heat entering reactor 1 that after enamel spiral heat exchanger 5 carries out heat exchange, circulate.After reaction is accomplished, close circulation valve 6, open discharging valve 7, material is through 7 outputs of discharging valve.
