Abstract
The utility model discloses a sulfonating kettle for peri acid production, which comprises a kettle body (1) and a kettle cover (3) used for closing the kettle body (1). The sulphonating kettle is characterized in that the kettle cover (3) is a double-layer sandwiched sealing body and provided with a water inlet (2) and a water outlet (4). When in production, naphthalene can not be condensed on the inner wall of the kettle cover, thereby avoiding affecting sulfonation of total acid and keeping production stable.
Description
Technical field
The utility model relates to produces sulfonation still, the especially kettle cover of sulfonation still that Schollkopf acid is used.
Background technology
In the Schollkopf acid production process, at first be that refined naphthalene is carried out sulfonating reaction at 60 ℃ in the sulfonation still.Existing sulfonation still comprise kettle and with the adaptive kettle cover of kettle to the kettle sealing, kettle cover is a single layer structure.In the production, in order to improve reaction speed, need naphthalene is dissolved each other with the concentrated sulfuric acid at 80 ℃, because the fusing point of naphthalene is 80 ℃, and characteristic with distillation, so have the distillation phenomenon to produce in the process of dissolving each other with the concentrated sulfuric acid, because kettle cover is a single layer structure, temperature is lower near the inwall of kettle cover, can on the pot cover inwall, condense after the naphthalene distillation, fall down again after the one-tenth bulk and get back in the pot, cause the fluctuation of sulfonation total acid bigger, be unfavorable for producing stable.
The utility model content
The purpose of this utility model is exactly solve to produce sulfonation still that Schollkopf acid uses can condense on the pot cover inwall after because of the naphthalene distillation, causes the fluctuation of sulfonation total acid big, the production problem of unstable.
The technical solution adopted in the utility model is: produce the sulfonation still that Schollkopf acid is used, it comprise kettle and with the kettle cover of sealing kettle, it is characterized in that the seal that described kettle cover constitutes for the double-jacket formula, kettle cover is provided with water inlet and delivery port.
Adopt technique scheme, during use from kettle cover all the time to the hot water of water inlet input temp greater than 80 ℃, flow out from delivery port again, the temperature of kettle cover inwall is remained more than 80 ℃, the inwall Yin Wendu of kettle cover is greater than the sublimation temperature of naphthalene like this, therefore can not condense at the inwall of kettle cover, thereby can not influence the sulfonation total acid, what help like this promoting producing is stable.
The utility model beneficial effect is: because the utility model kettle cover adopts double-decker, inside charges into hot water all the time, makes the sublimation temperature of kettle cover inner wall temperature greater than naphthalene, and naphthalene can not condense at the kettle cover inwall, does not therefore influence the sulfonation total acid, makes production stable.
