Various waste water, exhaust gases and waste residues generated in the process undergo proper treatment by the equipment, thus reducing environmental pollution. And the final products have high purity, stable quality and good performance, with the color and purity all achieving the first grade or a superfine grade.
Description
Technical field
The invention belongs to the Gum Rosin production field, be specifically related to a kind of modified rosin resin production equipment.
Background technology
Modified rosin resin carries out the esterification preparation with tetramethylolmethane mainly by carrying out addition reaction earlier after rosin and MALEIC ANHYDRIDE (abbreviation cis-butenedioic anhydride) fusion under catalyst action.That this modified rosin resin has is fast light, resistance to oxidation and softening temperature advantages of higher, be usually used in the reinforcement sizing agent in the paper industry, also be the important source material that paint, printing ink, tackiness agent etc. are produced, also can be widely used in the super infusion of concrete, tackiness agent, pull out the preparation of aqua and other Chemicals.
But it is main that the production unit of existing modified rosin resin adopts intermittent type more, and production efficiency is lower.Also be easy to generate waste gas and waste water in process of production, produce a large amount of light constituents during as esterification, as untimely processing meeting environment is produced and pollute.Existing equipment lacks reacting the aftertreatment of back product, causes the instability of quality product easily.Addition reaction and esterification reaction temperature in the modified rosin resin preparation process are higher, and about 160~210 ℃, molten-bath and reactor be not as handling especially, and thermosteresis is bigger.
Summary of the invention
The objective of the invention is on the basis of existing installation, to transform, thereby provide a kind of pollutent of generation few, a whole set of production unit of modified rosin resin that energy-conserving and environment-protective, product performance are stable.
Purpose of the present invention can reach by following measure:
A kind of modified rosin resin production unit, comprise modified rosin resin reactor, rosin molten-bath and cis-butenedioic anhydride molten-bath, also be provided with filtration unit, refrigerating unit and adsorption tower, described filtration unit communicates by the material outlet of pipeline with described modified rosin resin reactor, described filtration unit is provided with products export and vapour outlet, described products export communicates with described refrigerating unit by pipeline, and described vapour outlet communicates with described adsorption tower by pipeline.
Be provided with rosin inlet and cis-butenedioic anhydride inlet at modified rosin resin reactor top, the material outlet of rosin molten-bath communicates with described rosin inlet by the rosin transfer line, and the material outlet of cis-butenedioic anhydride molten-bath communicates with described cis-butenedioic anhydride inlet by pipeline.Directly feed the loss that can cause the rosin heat in the reactor after the rosin fusion, therefore outside rosin molten-bath and rosin transfer line, attemperator is set respectively,, can avoid energy waste to the full extent as muff etc. by pipeline.Attemperator also is set outside the modified rosin resin reactor can ensures the control of reactor internal temperature.
This equipment also is provided with cooling tower, is provided with pneumatic outlet at modified rosin resin reactor top, and this pneumatic outlet communicates with described cooling tower by pipeline.On the pneumatic outlet of modified rosin resin reactor and the pipeline between the described cooling tower, can also be provided with vacuum pump.Carrying out the esterification later stage, can directly will carry out refrigerated separation in the light constituent suction cooling tower of generation, collecting each component and technology and generate water, respectively reuse or the concentrated burning disposal of carrying out by vacuum pump.
Filtration unit in this equipment can be removed the most of impurity in the product, and then can directly obtain finished product through apparatus for supercooling the aftertreatment that becomes more meticulous of reacted product.Filtration unit preferably adopts kieselguhr filter.The waste residue that kieselguhr filter produces focuses on after collecting.
Adsorption tower in order to remove produce in the filtration unit filtration procedure or reactor in pollutent in the steam that produces, adsorption tower preferably adopts activated carbon adsorber, the gas after the absorption can directly discharge, waste active carbon focuses on after collecting.
The present invention can significantly reduce the loss of energy in rosin fusion, conveying and the reaction process, keeps the temperature of reactor; This equipment has all carried out suitable disposal with various waste water, waste gas and the waste residue that technology produces, and has reduced the pollution to environment.The product purity height of finally preparing, steady quality, performance are good, and its color and luster and purity have all reached one-level or superfine.
