Description
Technical field
This utility model is related to field of heat exchange equipment, specially a kind of new sulfur trioxide autoclave vaporizer.
Background technology
Sulfan production is to heat 32% oleum in heat exchanger, the sulfur trioxide that evaporation wherein dissociates
Gas, sulfur trioxide gas are condensed again to generate sulfan product.
Current sulfur trioxide evaporator, generally vertical tube-type heater, on the heaters portion's design certain space make
For sulfur trioxide evaporating space；Heating medium typically from sulfate system itself pyrolytic conversion gas come heat oleum evaporation
Sulfur trioxide gas.
Some enterprises do not possess and are used as heating medium using pyrolytic conversion gas, but using water vapour as evaporating three oxygen
Change the thermal source of sulfur, the pattern of employing is generally vertical common tubular heat exchanger structure, and the tube sheet at tubulation two ends is single tube plate,
At the numerous tube sheet of solder joint, manufacture or during production run at which, cold fluid and hot fluid can occur unavoidably phase occurs at tube sheet
Mutually leakage problem, once steam occurs at tube sheet leaking in oleum, can cause serious accident, because water vapour with
Oleum can occur vigorous reaction, generate the very strong dilute sulfuric acid of corrosivity, and release substantial amounts of heat, such as process too late
When, the lighter causes equipment to damage, and severe one can cause an explosion accident.
Utility model content
The purpose of this utility model is the risk that accident occurs to reduce sulfur trioxide evaporator, there is provided a kind of safety can
The sulfur trioxide autoclave vaporizer for leaning on.
The technical scheme for realizing above-mentioned purpose is：A kind of new sulfur trioxide autoclave vaporizer, including horizontally disposed kettle
Sandwich type element, the upper center of autoclave housing are provided with sulfur trioxide gas outlet, and the upper end of autoclave housing is provided with oleum and enters
Mouthful, the lower end of autoclave housing is provided with oleum outlet；
Some U-tubes are provided with autoclave housing, the left end of autoclave housing is connected with front-end pipe box, arrange in front-end pipe box
There is demarcation strip, demarcation strip is by front-end pipe box even partition into two not connected first chambers and second chamber, first chamber
On be connected with steam inlet, be connected with steam (vapor) outlet in second chamber；
It is characterized in that：Be provided with inner side tube sheet and outside tube sheet between front-end pipe box and autoclave housing, inner side tube sheet with
Autoclave housing seal connects, and is tightly connected, between leaving between inner side tube sheet and outside tube sheet between outside tube sheet and front-end pipe box
Gap, and close cavity is connected as by spacer pipe directly, the bottom of seal cavity is connected with sulfur trioxide leakage alarm；
The two ends of the U-tube in autoclave housing pass through inner side tube sheet, spacer pipe, outside tube sheet, and connect front-end pipe box, U
It is tightly connected between the two ends of shape pipe and inner side tube sheet, outside tube sheet, the two ends of every U-tube are located at dividing for front-end pipe box respectively
Dividing plate both sides.
Further, manhole is offered on the demarcation strip, be sealedly connected with dismountable cover plate on manhole.
Further, absorbent cotton is coated with the U-tube between the inner side tube sheet and outside tube sheet.
The beneficial effects of the utility model：
1st, this utility model structure is novel, reasonable in design, safe and reliable to operation, and vaporizer front end tube sheet is using two-tube hardened
Structure, it is to avoid leak at the very many tube sheets of solder joint, it is ensured that sulfur trioxide evaporator safe and reliable operation.
2nd, seal cavity is connected as by spacer pipe between inner side tube sheet and outside tube sheet, the bottom of seal cavity is connected with
Sulfur trioxide leakage alarm, enables outside tube sheet, the leakage situation between inner side tube sheet and U-tube to be found in time, just
In maintenance.
3rd, manhole is offered on demarcation strip, be sealedly connected with dismountable cover plate on manhole, thus can be in front-end pipe box
Pressure testing detection is carried out after installation to U-tube, and is easy to the within the chamber to front-end pipe box to carry out daily maintenance and cleaning
Work.
4th, be coated with absorbent cotton on the U-tube between inner side tube sheet and outside tube sheet, occur leakage when, water vapour with send out
The dilute sulfuric acid that cigarette sulfuric acid reaction is produced is attracted on absorbent cotton, reduces the damage to equipment.
