Abstract
本实用新型提供了一种新型搪瓷反应釜。搪瓷反应釜的供热是由内加热器提供。由蒸汽分布管、加热列管和蒸汽冷凝液收集管组成鼠笼式结构的内加热器，其外表镀有搪玻璃。内加热器可使用4.0MPa的过热蒸汽供热，加热温度可达400℃。用作高温(≥158℃)、耐腐蚀的反应设备。
The utility model provides a novel enamel reaction kettle. The heating of the enamel reactor is provided by the internal heater. The internal heater of squirrel cage structure is composed of steam distribution pipe, heating tube and steam condensate collection pipe, and its surface is coated with glass lining. The internal heater can use 4.0MPa superheated steam for heating, and the heating temperature can reach 400°C. Used as high temperature (≥158°C), corrosion-resistant reaction equipment.
Description
Technical field
The utility model belongs to the chemical industry equipment field, relates to enamel reaction still.
Background technology
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 utility model content
The purpose of this utility model provides a kind of high temperature (〉=158 ℃), Fast Heating, corrosion resistant enamel reaction still.
Novel a kind of enamel reaction still of the present utility model, mode of heating is 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.
Description of drawings
Fig. 1 is a reactor center line cutaway view.
Below in conjunction with Fig. 1 the utility model embodiment is elaborated.
The specific embodiment
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 4.0bFa, 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.
