Outside the kettle of melting kettle, sulfonation still, hydrolysis kettle and condensation still, be equipped with and add hot jacket, not only can give the reactor even heating, can also be with unnecessary heat by heat transfer medium flows adding in the hot jacket to other reactors.The hot jacket that adds outside each still is in series by the heat-conducting medium conduit and forms under the round-robin situation, more can make heat fully mobile at each still place.Can also the heat-conducting medium pump be set at heat-conducting medium conduit place, circulate power to provide.
A kind of approach that preferably circulates of heat-conducting medium is as follows: melting kettle adds hot jacket and adds hot jacket by the heat-conducting medium conduit with the sulfonation still and communicate, the sulfonation still adds hot jacket and adds hot jacket by heat-conducting medium conduit and hydrolysis kettle and communicate, hydrolysis kettle adds hot jacket and adds hot jacket by the heat-conducting medium conduit with the condensation still and communicate, and the condensation still adds hot jacket and adds hot jacket with melting kettle again by the heat-conducting medium conduit and communicate; Thereby medium flows by adding the circulation passage internal recycle that hot jacket and heat-conducting medium conduit constitute at this, reaches the purpose that cuts down the consumption of energy as far as possible.
Also be provided with the sulfuric acid inlet on the sulfonation still, this sulfuric acid inlet links to each other with sulfuric acid volume pump or sour scale tank, in order to add the required sulfuric acid of sulfonation.
Hydrolysis kettle is provided with the hydrolysis water inlet, and this hydrolysis water inlet links to each other with hydrolysis water volume pump or water tank.
The condensation still is provided with the formaldehyde inlet, and this formaldehyde inlet links to each other with formaldehyde volume pump or formaldehyde storage tank.
In and still be provided with liquid caustic soda inlet, this liquid caustic soda inlet links to each other with the liquid caustic soda volume pump, in order to adding neutralization reaction desired raw material.
The beneficial effects of the utility model:
Device of the present utility model can accurately be controlled the reaction conditions of each reaction, makes the very fast and reaction fully of sulfonation reaction, hydrolysis reaction, condensation reaction and neutralization reaction, has thickly guaranteed quality product.Each reactor good heat insulation of while, the heat utilization efficiency height has reduced energy consumption as much as possible.
