Second end socket 140 is provided with condensation-water drain 141, and hot steam import 131 passes through carborundum heat exchanger tube with condensation-water drain 141
120 connections, that is, when needing to carry out the sulfuric acid in corrosion-proof casing 110 heating concentration, hot steam or conduction oil are from hot steam
Import 131 enters in the first end socket 130, enters stream in carborundum heat exchanger tube 120 in the opening by carborundum heat exchanger tube 120
It is dynamic, and flow into the second end socket 140, then flowed out from condensation-water drain 141.Preferably, condensation-water drain 141 is located at the second end socket
140 lower end, facilitates condensed water to flow out.
Sulfuric acid is heated by steam or conduction oil, adjusts temperature control all more convenient, is adapted to automation control
System.Heating concentration is carried out to dilute sulfuric acid using carborundum heat exchanger tube 120, there is very high thermal conductivity, high intensity, high temperature resistant and prevent
Acid and alkali corrosion characteristic, is adapted to the environment such as high temperature, high pressure, strong acid and highly basic, makes horizontal evaporator 100 that there is concentration well to imitate
Fruit, can also extend the service life of equipment, reduce production cost.
For the leakproofness of 120 and first anti-corrosion tube sheet 150 of carborundum heat exchanger tube and the second anti-corrosion tube sheet 160, every
The first anti-corrosion tube sheet 150 is fixed in one end of carborundum heat exchanger tube 120 by the first sealing structure 210, and the other end passes through second
Sealing structure 220 is fixed on the second anti-corrosion tube sheet 160, makes 120 and first anti-corrosion tube sheet 150 and second of carborundum heat exchanger tube anti-
The connection of rotten tube sheet 160 is more firm, i.e. 120 and first anti-corrosion tube sheet 150 of carborundum heat exchanger tube and the second anti-corrosion tube sheet 160
Connection sealing it is more preferable, avoid sulfuric acid from revealing, improve the safety in utilization of equipment；Meanwhile also avoid carborundum heat exchanger tube 120
Vibration is produced under sulfuric acid and the washing away of steam or conduction oil.
Specifically, Fig. 4 is the structure diagram of the first sealing structure 210 in horizontal evaporator 100 provided in this embodiment.
Also referring to Fig. 1 and Fig. 4, in the present embodiment, each first sealing structure 210 includes the first clamp nut 211, the first anti-corrosion
212 and first preserving and sealing circle 213 of gasket, is provided with first through hole 151, the first clamp nut 211 on the first anti-corrosion tube sheet 150
It is arranged in first through hole 151, the first anti-corrosion gasket 212 is set between first clamp nut 211 and the first anti-corrosion tube sheet 150,
120 one end of carborundum heat exchanger tube is arranged in the first clamp nut 211,120 and first clamp nut 211 of carborundum heat exchanger tube it
Between the first preserving and sealing circle 213 is set.The stable chemical performance of carborundum, will not be by sulfuric acid corrosion；Thermal conductivity factor is high, carborundum
Heat in heat exchanger tube 120 can be easy to pass out, and heating concentration is carried out to sulfuric acid, and thickening efficiency is high；Thermal coefficient of expansion
It is small, it under the action of steam or conduction oil, will not deform, increase service life；Wear-resisting property is good, and sulfuric acid is steamed in corrosion
In hair device housing when flowed, it is caused to wash away, will not damage, wear, under harsh operating mode from
Influence.Thus it is possible to as carborundum heat exchanger tube 120, there is good advantage.
Since carbofrax material hardness is big, crisp, so, the function of the first sealing structure 210 and second seals structure 220
More important, it cannot form carborundum heat exchanger tube 120 and extrude, and ensure good leakproofness again, so, compressed first
First anti-corrosion gasket 212,120 and first clamp nut of carborundum heat exchanger tube are set between 211 and first anti-corrosion tube sheet 150 of nut
First preserving and sealing circle 213 is set between 211, i.e., sets first to prevent between 120 and first clamp nut 211 of carborundum heat exchanger tube
Rotten sealing ring 213, can there is good sealing effect, meanwhile, the first anti-corrosion gasket 212 has with the first preserving and sealing circle 213
Certain elasticity, avoids that carborundum heat exchanger tube 120 is caused to extrude, allows it to be destroyed, and increase carborundum heat exchanger tube 120 makes
Use the service life.
The 26S Proteasome Structure and Function of first sealing structure 210 and second seals structure 220 is identical, and installation site is different.Each
Second seals structure 220 includes the second clamp nut, the second anti-corrosion gasket and the second preserving and sealing circle, the second anti-corrosion tube sheet 160
On be provided with the second through hole, the second clamp nut is arranged in the second through hole, the second clamp nut and the second anti-corrosion tube sheet 160 it
Between the second anti-corrosion gasket is set, one end away from the first clamp nut 211 of carborundum heat exchanger tube 120 is arranged at the second compression spiral shell
In mother, the second preserving and sealing circle is set between 120 and second clamp nut of carborundum heat exchanger tube.High-temperature steam compresses spiral shell from first
Nut bore at mother 211 and the into and out carborundum heat exchanger tube 120 of nut bore at the second clamp nut, make steam and condensation
Water circulates.Or high temperature heat conductive oil from the nut bore at the first clamp nut 211 and the nut bore at the second clamp nut into
Enter or flow out carborundum heat exchanger tube 120, high temperature heat conductive oil is circulated.
In the present embodiment, the first anti-corrosion gasket 212 and the second anti-corrosion gasket can be gasket made of various anti-corrosion materials,
