Description
Technical field
The utility model relates to the synthetic chloroprene rubber field, is specially a kind of chloroprene monomer preparation facilities.
Background technology
The important chemical property of chloroprene is can polymerization to generate polymkeric substance, and chloroprene is extremely unstable, air, heat, illumination, water, and the oxide compound of iron in the presence of voluntarily polymerization get faster.Because the difference of condition, the polymerization of chloroprene can obtain several different polymers, wherein ω-polymeric formation brings very adverse influence and unsafe factor to production, it can be drawn chloroprene and continue polymerization from gas phase and liquid phase, thereby increase volume and form blocks of solid, just can make equipment and line clogging in a short time, must in time remove, and high more its growing amount of chloroprene ω-polymeric growing amount temperature in the identical time is many more.According to the above conclusion that chloroprene and polymeric physico-chemical property thereof are analyzed, prevent and reduce the polymeric generation of chloroprene, in process system, must take anoxybiotic, low temperature, dewater, lucifuge and prevent the measure that the oxide compound of iron produces.
At present, in chloroprene monomer preparation process, by usually having a spot of acid and moisture in decompression, the smart chloroprene produced of rectifying two towers, these sour waters are by being placed with in Calcium Chloride Powder Anhydrous (CaCl2) and the soda ash (NaCO3) and drying tower, in and drying tower in, wherein Calcium Chloride Powder Anhydrous is used for absorbing the moisture in the chloroprene, during soda ash is used for and material in acid, obtain qualified smart chloroprene.To in and the temperature monitoring of smart chloroprene solution in the drying tower, medial temperature is at 3～5 ℃.Extremely unstable according to above-mentioned chloroprene, air, heat, illumination, water, and the oxide compound of iron in the presence of polymerization voluntarily, wherein decomposition reaction easily takes place and brings out the autohemagglutination of chloroprene when being higher than 0 ℃ in the interpolymer of chloroprene and oxygen.
Because current technology makes smart chloroprene delivery temperature higher (3～5 ℃), bring out polymeric generation easily, thereby can not normally move with drying tower and finished product storage tank in causing, in order not influence the quality of product, guarantee carrying out smoothly of production, need in and the polymer that generates in drying tower and the finished product storage tank often clear up, not only influence the quality of product, cause the material waste, simultaneously because the polymer that generates can absorb airborne oxygen, form complicated oxide compound, spontaneous combustion takes place easily, bring very large potential safety hazard to production, in scale removal process, the cleaning personnel directly contact with material, and the harm employee is healthy, and labour intensity is big.
Summary of the invention
The utility model is in order to solve in the existing chloroprene monomer preparation process, in and in drying tower and the smart chloroprene pan tank temperature higher and bring out polymer and generate, influence quality product, cause problems such as material waste, a kind of chloroprene monomer preparation facilities is provided.
The utility model is to adopt following technical scheme to realize: chloroprene monomer preparation facilities, comprise rectifying tower, be installed on the continuous complete condenser of heating kettle, the condenser that is installed in the rectifying tower top, the partial condenser that links to each other with condenser and partial condenser of rectifying tower below, the discharge port of partial condenser and complete condenser through first pipeline with in and the drying tower opening for feed be communicated with, in and the drying tower discharge port be communicated with smart neoprene pan tank opening for feed through second pipeline, innovative point of the present utility model is to be equipped with on first pipeline at least one blanking water cooler.Adopt structure design of the present utility model, since chloroprene decompression, rectifying two tower blankings in and set up the blanking water cooler between the drying tower, smart chloroprene delivery temperature is dropped to-2～-5 ℃ by 3～5 ℃, make in and drying tower and smart chloroprene pan tank polymer generate and be effectively controlled, thereby improved quality product.
Described blanking water cooler is a shell and tube cooler, in comprising, its structure establishes the housing of tubulation, case top is provided with material inlet, the material outlet that is communicated with first pipeline, the housing upper and lower is respectively equipped with heat-eliminating medium outlet and cooling medium inlet, housing bottom is provided with the sour water collecting chamber, and housing is provided with the sour water discharge outlet that connects with the sour water collecting chamber.Enter the material of water cooler by material inlet, when lowering the temperature by heat-eliminating medium, the small amount of acid that wherein is mingled with is separated with moisture, and is deposited in the sour water collector, regularly discharging.Thus in normal productive process, in and drying tower need not to add again calcium chloride and soda ash.
Compared with prior art, the utility model is simple in structure, improvement is reasonable, result of use is fine, reduced the material waste in the chloroprene monomer production process, reduced the production cost of chloroprene, improved the quality product of chloroprene since in and drying tower and smart chloroprene pan tank polymer generate and be effectively controlled, avoided scale removal process, thereby reduced the material harm healthy to the employee, applied range is applicable to that chloroprene rubber synthesizes the field.
