Abstract
The utility model discloses a temperature measuring device of a sulfonation kettle. The device comprises a first temperature measuring instrument and a second temperature measuring instrument, wherein the first temperature measuring instrument is installed at the top part of the sulfonation kettle and stretches from the top part into the sulfonation kettle; and the second temperature measuring instrument is installed at the bottom of the sulfonation kettle and stretches from the bottom into the sulfonation kettle. The temperature measuring device can accurately measure the material temperature in the sulfonation kettle, greatly improve the contents of main products and greatly reduce the generation of byproducts.
Description
Technical field
The utility model relates to a kind of temperature measuring equipment, relates in particular to a kind of sulfonation still temperature measuring equipment.
Background technology
Sulfonating reaction is one critical process in the H acid production process, H acid, it is 1-amino-8-naphthol-3, the 6-disulfonic acid, it is important naphthalene series dye intermediate, it is mainly used in and produces directly, acid, reactive dye and azo dyes intermediate, as acid day blue, direct kind surplus the black Reactive Brilliant Red K-2BP etc. 90, also can be used for pharmaceuticals industry.Sulfonating reaction is very strict to the requirement of temperature, and the trickle fluctuation of the temperature difference will have very big influence to the quality and the yield of product.The sulfonating reaction still is the key equipment of sulfonating reaction, sulfonating reaction control ratio to temperature of charge in the H acid production process is strict, require ± 1 ℃, and the temperature measuring equipment of present sulfonation still is when just beginning to feed intake, material ratio is measured not accurate enoughly more after a little while in the still, can't measure actual temperature, and can only measure material steam state temperature in the still, the inaccurate content of major product that will make of temperature survey reduces like this, and the growing amount of byproduct improves, reduce the product production rate, reduced the quality of product.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of sulfonation still temperature measuring equipment is provided, and this temperature measuring equipment can be measured the temperature of charge in the sulfonation still more accurately, has improved the content of major product greatly, greatly reduces the generation of byproduct.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of sulfonation still temperature measuring equipment, comprise first temperature measuring set and second temperature measuring set, described first temperature measuring set is installed on the top of sulfonation still and extend into sulfonation still inside from the top, and described second temperature measuring set is installed on the bottom of sulfonation still and extend into sulfonation still inside from the bottom.
As a kind of preferred scheme, the top of described sulfonation still is provided with temperature and surveys mouth, and described first temperature measuring set comprises the first sleeve thermometer, and the described first sleeve thermometer is installed on described temperature and surveys a mouthful place.
As a kind of preferred scheme, described second temperature measuring set comprises the second sleeve thermometer, and the described second sleeve thermometer stretches into described sulfonation still inside from the discharge port of sulfonation still bottom.
After having adopted technique scheme, effect of the present utility model is: because described sulfonation still temperature measuring equipment, comprise first temperature measuring set and second temperature measuring set, described first temperature measuring set is installed on the top of sulfonation still and extend into sulfonation still inside from the top, described second temperature measuring set is installed on the bottom of sulfonation still and extend into sulfonation still inside from the bottom, therefore, first temperature measuring set and second temperature measuring set can and be calibrated temperature of charge in the sulfonation still and steam state temperature formation contrast, when beginning to throw material, material ratio more after a little while in the still, second temperature measuring set of bottom then can accurately measure the temperature in the sulfonation still, and the later stage material for a long time, identical with first temperature measuring set with the measurement data of second temperature measuring set, all can be used as actual temperature of charge numerical value, being convenient to like this has grasp more accurately to the temperature in the reactor, has improved the content of major product greatly, greatly reduces the generation of byproduct.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structure cutaway view of the utility model embodiment;
In the accompanying drawing: 1. sulfonation still; 2. first temperature measuring set; 3. second temperature measuring set; 4. discharge port; 5. stirring vane; 6. motor.
The specific embodiment
A kind of sulfonation still 1 temperature measuring equipment, as shown in drawings, described sulfonation still 1 comprises kettle, and described kettle is provided with charging aperture and discharge port 4, is rotatablely equipped with stirring vane 5 in the described kettle, and described stirring vane 5 is driven by motor 6.Described measurement mechanism comprises first temperature measuring set 2 and second temperature measuring set 3, described first temperature measuring set 2 is installed on the top of sulfonation still 1 and extend into sulfonation still inside from the top, and described second temperature measuring set 3 is installed on the bottom of sulfonation still and extend into sulfonation still inside from the bottom.The top of described sulfonation still 1 is provided with temperature and surveys mouth, and described first temperature measuring set 2 comprises the first sleeve thermometer, and the described first sleeve thermometer is installed on described temperature and surveys a mouthful place.Described second temperature measuring set 3 comprises the second sleeve thermometer, and the described second sleeve thermometer stretches into described sulfonation still 1 inside from the discharge port 4 of sulfonation still 1 bottom.
Operation principle of the present utility model is: material enters in the sulfonation still 1, motor 6 drives stirring vane 5 rotations material is mixed, early stage material more after a little while, 3 of second temperature measuring sets of bottom can accurately measure the temperature in the sulfonation still 1,2 of first temperature measuring sets are measured material steam state temperature, contrast and compare thereby form, and the later stage material for a long time, first temperature measuring set 2 is identical with the measurement data of second temperature measuring set 3, all can be used as actual temperature of charge numerical value, being convenient to like this has grasp more accurately to the temperature in the reactor, has improved the content of major product, greatly reduces the generation of byproduct.
