Abstract
The utility model provides a novel high temperature enamel reaction vessel. Heating of the enamel reaction vessel is provided by an inner heater. The inner heater which comprises a steam distributing tube, a heating column tube and a collecting duct for steam condensate is coated with glass lining. The inner heater can provide heat via overheated steam of 4.0 Mpa, therefore the heating temperature can reach as high as 400 degrees. The utility model can be used as a reaction equipment of high temperature (>=158 degree) and corrosion resistance.
Description
The utility model belongs to the chemical industry equipment field, relates to enamel reaction still.
The mode of heating of enamel reaction still has jacket steam heating and chuck heat-conducting oil heating at present.Jacket steam heating reactor is to provide thermal source by steam condensation in the chuck, and shortcoming is because of the steam pressure that uses in the chuck is up to 0.6MPa, so 158 ℃ heating-up temperature can only be provided.When requiring to be higher than 158 ℃, can only adopt electrical heating for some reaction temperature.Promptly fill conduction oil in chuck, by electrically heated rod heating conduction oil, conduction oil passes to reactive material with heat.Shortcoming is that electrical heating power consumption is big, and heat transfer rate is slow, and the thermal efficiency is low.
Chinese patent (the patent No.: 90216043) introduced a kind of novel still internal heater that is used for enamel reaction still, mainly by in kettle cover inserts still and to be lifted on some groups of surfaces on the kettle cover be that the U type metal tube of enamel is in series.But increase because of increasing of connecting port makes leakage point, need open several air inlets, air outlet valve when using, increased operation easier simultaneously because of U type pipe influences the stirring of material in the still in the still central distribution, and because of heater.
The purpose of this utility model provides a kind of high temperature (〉=158 ℃), Fast Heating, corrosion resistant enamel reaction still.
New type high temperature enamel reaction still of the present utility model, mode of heating are interior heating.Internal heater is made up of steam inlet pipe, distribution of steam pipe, heating tubulation, steam condensate collecting pipe, steam condensate efferent duct, wherein the main part likeness in form mouse cage that is made of distribution of steam pipe, heating tubulation and steam condensate collecting pipe.Internal heater outer surface and enamel reaction still inner surface all are coated with enamel.
Size according to the rerum natura decision heater of the rerum natura of reactive material, technological requirement, heating steam, wherein the internal radius ring of distribution of steam pipe formation must not be less than the diameter of enamel reaction still agitator, the diameter of distribution of steam pipe is definite according to steam flow, but must not be less than 2 times of heating tubulation diameter; Requirement condition to radical is as follows: arrangement pitches must not be less than 50mm on the distribution of steam pipe promptly to heat tubulation.The size of steam condensate collecting pipe, diameter are identical with the distribution of steam pipe.Heating tubulation upper end and the welding of distribution of steam pipe, heating tubulation lower end and the welding of steam condensate collecting pipe, outer part of distribution of steam pipe and steam condensate collecting pipe still and corresponding flange welding, other structures are with common enamel reaction still.
The enamel reaction still of the utility model manufacturing can use middle pressure steam as heat supply, and heating-up temperature can be up to 400 ℃, and firing rate is fast.Because internal heater is built in the reactant, so heat loss is little, the steam utilization height has invigoration effect to mixing, the mass transfer of material, and operating cost is low.
Fig. 1 is a reactor center line cutaway view.
Below in conjunction with Fig. 1 the utility model embodiment is elaborated.
When a kind of organic chemical industry's intermediate of polymerization reacted, used enamel reaction still volume was 1.2m
3, 35 of internal heater heating tubulations, heat exchange area is 5.2m
2Use superheated steam (370 ℃) heat supply of 4.0MPa, steam is entered the distribution of steam pipe 2 of internal heater by steam inlet pipe 1, by distribution of steam pipe 2, steam evenly enters heating tubulation 3, and under the stirring of the agitator 4 that is driven by motor 5, each heats steam and the interior abundant heat exchange of material of reactor in the tubulation 3, the steam condensate that condensation is got off is pooled to condensate collector tube 7, and last condensate liquid is discharged heater by condensate drain 6.
The 1000Kg solvent can be heated to reaction temperature by normal temperature in 0.6hr, can finish 400Kg urea melting, polymerisation subsequently in 2.5hr.Whole process need consume steam 0.5t, always needs 3.1hr consuming time.
Comparative Examples:
When polymerization and embodiment like products, used reactor volume is identical with embodiment 1, and heat exchange area is 5.5m
2Adopt electrical heating (heating conduction oil in the conduction oil of electrically heated rod in chuck) mode heat supply, electrically heated rod power is 48KW, and heating 1000Kg solvent to the reaction temperature identical with embodiment 1 needs 3hr, finishes 400Kg urea melting, polymerisation subsequently in 5hr.Whole process electricity consumption 384KWH always needs 8.0hr consuming time.
Claims (2)
1, a kind of high-temperature tubring reactor, form by still shell, internal heater and agitator etc., internal heater is made up of steam inlet pipe, distribution of steam pipe, heating tubulation, steam condensate collecting pipe, steam condensate efferent duct, it is characterized in that, the main part form mouse cage that the distribution of steam pipe of internal heater, heating tubulation, steam condensate collecting pipe constitute, internal heater outer surface and enamel reaction still inner surface all are coated with enamel.
2, enamel reaction still according to claim 1, it is characterized in that, the diameter of distribution of steam pipe is determined according to steam flow, but should be greater than 2 times of heating tubulation diameter, arrangement pitches should be greater than 50mm on the distribution of steam pipe for the heating tubulation, the size of steam condensate collecting pipe, diameter are identical with the distribution of steam pipe, heating tubulation upper end and the welding of distribution of steam pipe, heating tubulation lower end and the welding of steam condensate collecting pipe, outer part of distribution of steam pipe and steam condensate collecting pipe still and corresponding flange welding.
