Abstract
The utility model relates to a reboiler which comprises a housing, a charging port and a discharging port that are respectively arranged at two ends of the housing; a heating jacket is arranged on an external sealing ring on the sidewall of the housing and forms a heat exchanging channel with the wall surface of the housing; and the upper part and the lower part of the heating jacket are respectively provided with a medium inlet and a medium outlet which are communicated with the heat exchanging channel. The utility model provides a reboiler with longer service life, aiming at solving the problem that the shell and tube heat exchanger in the existing reboiler often has short service life.
Description
Technical field
The utility model relates to a kind of reboiler.
Background technology
The used rectifying column reboiler of conventional production anhydrous hydrofluoric acid adopts the tubular heat exchanger structure, and this heat exchanger is arranged in the reboiler housing, and its technology is that anhydrous hydrofluoric acid is walked tube side, and steam is walked shell side.There is following problem in the reboiler of this structure: 1, because corrosion and heating make tubular heat exchanger short service life, can only use about 2 months; 2, tubular heat exchanger leakage problem occurs through regular meeting; not only seriously restricted normally carrying out of producing; and anhydrous hydrofluoric acid leaks in the steam condensate (SC) of outside; can bring a series of problem: such as; if condensed water recycled the recirculated water make refrigeration machine words with the purpose that reaches energy-saving and emission-reduction; in case anhydrous hydrofluoric acid leaks the heat exchanger that might corrode refrigerator, may pollute freezing liquid when serious.Therefore need long reboiler in a kind of service life.
The utility model content
The purpose of this utility model provides long reboiler in a kind of service life, to solve tubular heat exchanger short problem in service life in the existing reboiler.
For achieving the above object, the utility model adopts following technical scheme: a kind of reboiler, comprise housing and the charging aperture and the discharging opening that are divided into the housing two ends, described housing sidewall outer seal ring is provided with heating jacket, form heat exchanger channels between this heating jacket and the shell wall side, the upper and lower part of heating jacket is provided with medium import and the media outlet that is connected with heat exchanger channels respectively.
Described charging aperture is located at housing bottom, and described heating jacket bottom extends to the position of housing bottom near charging aperture.
The utility model is established heating jacket at the housing sidewall outer seal ring of reboiler, between heating jacket and housing, form heat exchanger channels, do not intersect owing to do not exist between the inner cavity chamber of this heat exchanger channels and housing, in use, heat medium flow carries out heat exchange through heat exchanger channels and with material in the housing, even there is leakage problem in the charging aperture on the housing, the material that leaks out can not enter in the heat exchanger channels yet, thereby can not corrode heat exchanger channels, thereby prolonged its service life greatly.
Charging aperture is located at housing bottom, and the heating jacket bottom extended to housing bottom near behind the position of charging aperture, in use, the heat exchanger channels bottom can provide heat for the material that enters from the housing bottom charging aperture, to accelerate the reaction speed of material in the housing chamber.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 be the utility model reboiler 8, include housing 1, be arranged at the charging aperture 6 and the discharging opening 7 that is arranged at housing 1 top of housing 1 bottom, be provided with heating jacket 2 at housing 1 sidewall outer seal ring, and heating jacket 2 bottoms extend to the position of housing 1 bottom near charging aperture, between heating jacket 2 and shell wall side, form heat exchanger channels 3, be provided with medium import 4 and the media outlet 5 that is connected with heat exchanger channels 3 in the upper and lower part of heating jacket 3 respectively.
The utility model is established heating jacket 2 at the housing 1 sidewall outer seal ring of reboiler 7, between heating jacket 2 and housing 1, form heat exchanger channels 3, do not intersect owing to do not exist between the inner cavity chamber of this heat exchanger channels 3 and housing 1, when using as mordant materials such as anhydrous hydrofluoric acids, hydrofluoric acid enters in the housing 1 from charging aperture 6, through carrying out heat exchange with the steam that is input to heat exchanger channels 3 from medium import 4, even there is leakage problem in the hydrofluoric acid charging aperture 6 of housing 1 bottom, the hydrofluoric acid that leaks out can not enter in the heat exchanger channels 3 yet, thereby can not corrode heat exchanger channels 3, thereby prolonged its service life greatly.
Claims (2)
