Description
Technical field
The utility model relates to chemical field, what be specifically related to is 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) production system.
Background technology
The traditional technology that 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) is produced generally is to adopt one still process: acetic acid and the water of technique amount are joined in the reactor, then the phosphorus trichloride with the technique amount splashes in the reaction through dripping tank at leisure, react with the acetic acid and the water that add in advance, generate Acetyl Chloride 98Min. and phosphorous acid; Phosphorus trichloride dropwises, and logical steam heats material in the reaction chuck, and Acetyl Chloride 98Min. refluxes after the supercooler condensation because of the low start vaporizer of boiling point, until temperature rises to 120 ℃, is incubated one hour; Insulation adds water and is hydrolyzed after finishing, and then directly passes into steam and rushes steaming, and the acetic acid that produces in the material is steamed, and gets finished product.The characteristics of this technique be exactly whole reaction process all be in a reactor, to finish, therefore the utility appliance, the public utility that are connected with reactor are more: every reactor need to be equipped with the utility appliance such as two water coolers, acetometer measuring tank, phosphorus trichloride test tank, water measuring tank, Acetyl Chloride 98Min. receiving tank, reacting kettle jacketing should lead to steam, lead to again water coolant, cause the production cycle long (take 5000 liters of reactors as example, approximately 50 hours production cycle), material pipe is many, control facility is complicated, valve switches frequent, misoperation easily occurs; In whole production process, temperature span is larger simultaneously, and the utilization of some equipment all is interim, causes the idleness of equipment of production process, the waste resource.
The utility model content
The utility model is according to above-mentioned deficiency, provide a kind of equipment simple, easy to operate, install, use flexibly, according to the production technology characteristic of product, select targetedly equipment, reach optimum process mix and best control measures, with the investment that economizes most, create stable, a reliable production system.
For achieving the above object, the technical solution of the utility model is a kind of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) production system, described 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) production system is comprised of dropping system, synthesis system and punching steaming system, wherein dropping system is connecting synthesis system, and synthesis system is connecting punching steaming system.
Described dropping system comprises air-cooled tubulation reaction vessel.
Described synthesis system comprises glassed steel reaction vessels equipment.
Described punching steaming system comprises the reverse vapour formula hydrolysis tower that rushes.
Described punching steaming system comprises vertical multiple effect bubble absorption tank.
By the beneficial effect after the technique scheme be: the utility model is according to the characteristics of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) production process, be divided into dropping, synthetic, three systems of punching steaming, each system selects the equipment that more is fit to targetedly, compare with traditional technology: the dropping system replaces glassed steel reaction vessels with air-cooled tubulation reaction vessel, water cooler also can change to the graphite modified polypropylene shell and tube cooler, adopts the chilled brine single stage cooling to get final product; Synthesis system and traditional technology are close, and reacting kettle jacketing only logical steam gets final product, and only connect two-stage cooler (circulating water and chilled brine cooling) on the kettle cover, save test tank, dripped tank etc.; Rush the steaming system and replace glassed steel reaction vessels with the reverse vapour formula hydrolysis tower that rushes, the tail gas that punching is steamed gets final product with the cooling of single-stage circulation watercooler, has also save test tank, has dripped tank etc.; Can save a large amount of investments.Because each segment process index is simple: the dropping system just drips phosphorus trichloride and water (or moisture acetic acid) in air-cooled tubulation reaction vessel, the control temperature of charge is no more than process value (such as 35 ℃), drip off a collection of, material is shifted, drip again a collection of, control indexes is relatively simple, easy, and the quality index of product is easier to improve; Synthesis system just heats up, insulating process, to the logical steam of reacting kettle jacketing, temperature of charge is constantly risen, until be raised to 120 ℃, is incubated one hour; Steam off, the pure water that adds the technique amount is hydrolyzed; The abundant disposable steaming system that rushes that all is transferred to of material after the hydrolysis, whole building-up process finishes, the production of preparing next batch of material, the thermal shock of equipment is less, has reduced the switching of valve, work-ing life that can extension device; Rushing the steaming system uses reverse operation of rushing after vapour formula hydrolysis tower or vertical multiple effect bubble absorption (air lift) tank simpler, after regulating the flow that material advances the flow velocity of tower and bottom steam, do not need to remake other adjustment, produce continuously and get final product, namely save time and laborsaving, even can realize unattended.
