Description
Technical field
This utility model relates to
A kind of hydrogen chloride synthetic furnace, a kind of heat reclaim unit for hydrogen chloride synthetic furnace.
Background technology
3 significant process of the development experience of hydrogen chloride synthetic furnace, first process is the steel synthetic furnace stage, whole burner hearth is steel design, steel water leg has been installed additional outside burner hearth, chlorine and hydrogen synthesizing chlorinated hydrogen: H2+Cl2=2HCL+184.6kj/mol in steel burner hearth, a large amount of heat energy that conbustion synthesis produces are taken away by cooling down water, after cooling tower air-cooler cools down, heat are arranged in the air, come back to steel jacket after cooling water temperature, complete to cool down water reciprocation cycle.Second process is two-into-one graphite synthesis phase, the graphitic synthetic furnace at this initial stage in stage is similar with the structure of steel stove, simply steel furnace has made graphite-structure into, graphite flue outer layer has installed steel water leg additional, utilize the water of chuck to cool down graphite flue, it is ensured that the safe operation of graphite flue, now, the amount of heat produced during hydrogen chloride synthesis is still to be arranged in the air, fails to recycle；3rd process is to be improved on the basis of second process, and circulating cooling water temperature is improved, the heat energy produced when reclaiming major part synthetic furnace reaction.But it is big to be because graphite furnace gallbladder fragility, and tension, bending strength are relatively low, and the steam pressure of institute's output can only control at below 0.4MPa, accesses the low-pressure steam pipe network connected specially, and the main steam range of factory can not be accessed.
Summary of the invention
The purpose of this utility model is, it is provided that a kind of heat reclaim unit for hydrogen chloride synthetic furnace.It is high that this utility model has tension, bending strength, and the feature that the steam pressure of output is big, additionally, this utility model also has the feature that resistance to corrosion is stronger.
The technical solution of the utility model: a kind of heat reclaim unit for hydrogen chloride synthetic furnace
, including upper condensate sump, upper condensate sump is provided with steam (vapor) outlet, and the lower section of upper condensate sump is provided with lower condensate sump, and lower condensate sump is provided with cooling water inlet, is connected through some heat exchange vertical tubes between lower condensate sump with upper condensate sump.
Be previously described for the heat reclaim unit of hydrogen chloride synthetic furnace, described upper condensate sump be arranged over upper flange, the lower section of lower condensate sump is provided with lower flange.
Being previously described for the heat reclaim unit of hydrogen chloride synthetic furnace, described upper condensate sump, lower condensate sump and heat exchange vertical tube are steel
, between adjacent heat exchange vertical tube, sealed steel bar separates.
The beneficial effects of the utility model: this utility model is by arranging upper condensate sump and lower condensate sump, and heat exchange vertical tube is set between upper condensate sump and lower condensate sump, surround heat exchange burner hearth, cooling water enters lower condensate sump from cooling water inlet, then after heat exchange vertical tube absorbs heat, form steam and enter upper condensate sump, flow out from steam (vapor) outlet, formed and close independent heat exchange structure, arranged side by side owing to using some heat exchange vertical tubes, compared with at graphite flue peripheral hardware displacement thermal jacket, the lifting surface area of wall scroll heat exchange vertical tube is less, therefore, it has higher tension, bending strength, so, this utility model is in the case of ensureing that equipment runs safety, the steam of energy output more high-vapor-pressure, factory steam house steward can be directly accessed.
It is proven: use after this utility model, in the case of ensureing that equipment runs safety, can the steam of output 0.8-1.2MPa vapour pressure.
In addition, owing to upper lower condensate sump of the present utility model and heat exchange vertical tube all use steel, and the hydrogen chloride gas in the burner hearth of steel is when temperature is less than less than 108 DEG C, hydrogen chloride condensed acid can be formed on steel hearth wall, corrosion heat exchange vertical tube, and owing to cooling water water temperature after cooling water inlet enters lower condensate sump is relatively low, if heat exchange vertical tube is mutually juxtaposed contact, the local temperature that the tube and tube below heat exchange vertical tube will certainly be caused to contact is relatively low and easily produces condensation acid, therefore, heat exchange vertical tube is separated by this utility model by utilizing sealing steel bar, seal the temperature that steel bar can keep higher, the place making the contact of the heat exchange vertical tube contacted therewith also can keep higher temperature, reduce the formation of condensation acid, enhance resistance to corrosion of the present utility model.
In sum, this utility model has tension, bending strength height, and the steam pressure of output is big, the beneficial effect that resistance to corrosion is stronger.
