Abstract
The invention relates to a heat exchanger with distribution discs. The heat exchanger comprises a lower tube box casing, a middle tube box casing, an upper tube box casing, a tube plate and a plurality of heat exchange tubes. A tube plate is arranged at the two ends of the middle tube box casing respectively. The plurality of the heat exchange tubes are arranged in the middle tube box casing through the tube plate, the lower tube box casing is connected with a lower end port of the middle tube box casing, the upper tube box casing is connected with an upper end port of the middle tube box casing, and a liquid inlet is formed in the upper end of the upper tube box casing. The heat exchanger is characterized by further comprising an upper liquid disc, a lower liquid disc, a spilling ring, a ribbed plate and a connection tube. The spilling ring is arranged on the outside of the lower end of the lower liquid disc, the upper liquid disc is arranged in the upper tube box casing at the lower end of the liquid inlet through the ribbed plate, and the lower liquid disc is arranged at the lower end of the upper tube box casing through the connection tube. Upper liquid falling holes are formed in the bottom of the upper tube box casing, lower liquid falling holes are formed in the bottom of the lower tube box casing, and the diameters of the upper liquid falling holes are larger than those of the lower liquid falling holes. By means of the heat exchanger, liquids can enter the heat exchange tubes uniformly.
Description
Technical field
The present invention relates to a kind of heat transmission equipment, particularly relate to a kind of heat exchanger with distributing disc.
Background technology
In current chemical industry is produced, heat exchanger comprises lower tube box shell, middle bobbin carriage shell, upper tube box shell, baffle plate, tube sheet and heat exchanger tube, a tube sheet is respectively provided with at middle bobbin carriage shell two ends, some heat exchanger tubes are arranged in middle bobbin carriage shell by tube sheet, lower tube box shell is connected to middle bobbin carriage shell lower port, upper tube box shell is connected to middle bobbin carriage shell upper port, fluid hole is provided with in the lower end of lower tube box shell, be provided with inlet opening in the upper end of upper tube box shell, baffle plate is arranged in the upper tube box shell of inlet opening lower end, in use, liquid flows into upper tube box shell from inlet opening and is flowed into heat exchanger tube by after baffle plate dispersion, flow out from fluid hole after flowing into lower tube box shell again, although liquid can be avoided directly to be flushed in heat exchanger tube at the block baffle plate at inlet opening place, reduce washing away of the tube head of exchange heat pipe, because baffle plate can not dispersed liquid, thus in the heat exchanger tube made, had liquid to flow into, the dry wall phenomenon of the but appearance had, the liquid flowed in heat exchanger tube is uneven, heat exchanger tube percentage elongation not only can be caused inconsistent, easily there is the tube head leakage phenomenon of heat exchanger tube, thus affect the quality of product.
Summary of the invention
For above-mentioned shortcoming, the object of the present invention is to provide a kind of heat exchanger that uniform liquid distribution can be made to enter the band distributing disc of heat exchanger tube.
Technology contents of the present invention is, a kind of heat exchanger with distributing disc, comprises lower tube box shell, middle bobbin carriage shell, upper tube box shell, tube sheet and heat exchanger tube; Respectively be provided with a tube sheet at middle bobbin carriage shell two ends, some heat exchanger tubes are arranged in middle bobbin carriage shell by tube sheet, and lower tube box shell is connected to middle bobbin carriage shell lower port, and upper tube box shell is connected to middle bobbin carriage shell upper port, is provided with inlet opening in the upper end of upper tube box shell; It is characterized in that it also comprises seal pot, lower seal pot, overflow circle, gusset and tube connector; Be provided with an overflow circle at upper seal pot lower end outside, upper seal pot is arranged in the upper tube box shell of inlet opening lower end by overflow circle by gusset, and lower seal pot arranges son in upper seal pot lower end by tube connector; Be provided with in the bottom of upper seal pot the fluid apertures that falls, be provided with whereabouts fluid apertures in the bottom of lower seal pot, the diameter of the fluid apertures that above falls is greater than whereabouts fluid apertures.
The present invention is compared with prior art had is a little: the present invention makes the liquid in inflow upper tube box shell equally distributedly drop in each heat exchanger tube by arranging two-layer liquid-receiving plate in upper tube box shell, namely liquid is avoided to exchange washing away of the tube head of heat pipe, also can prevent part heat exchanger tube from occurring dry wall phenomenon, there is the phenomenon easily revealed in the tube head avoiding heat exchanger tube, thus does not affect the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the local in A portion in Fig. 1 sends out figure large.
Specific embodiment
As depicted in figs. 1 and 2, a kind of heat exchanger with distributing disc, comprises lower tube box shell 1, middle bobbin carriage shell 2, upper tube box shell 3, tube sheet 4 and heat exchanger tube 5; A tube sheet 4 is respectively provided with at middle bobbin carriage shell 2 two ends, some heat exchanger tubes 5 are arranged in middle bobbin carriage shell 2 by tube sheet 4, lower tube box shell 1 is connected to middle bobbin carriage shell 2 lower port, and upper tube box shell 3 is connected to middle bobbin carriage shell 2 upper port, is provided with inlet opening 3.1 in the upper end of upper tube box shell 3; It is characterized in that it also comprises seal pot 6, lower seal pot 7, overflow circle 8, gusset 9 and tube connector 10; Be provided with an overflow circle 8 at upper seal pot 6 lower end outside, upper seal pot 6 is arranged in the upper tube box shell 3 of inlet opening 3.1 lower end by overflow circle 8 by gusset 9, and lower seal pot 7 arranges son in upper seal pot 6 lower end by tube connector 10; Bottom upper seal pot 6, be provided with the fluid apertures 6.1 that falls, bottom lower seal pot 7, be provided with whereabouts fluid apertures 7.1, the diameter of the fluid apertures that above falls 6.1 is greater than whereabouts fluid apertures 7.1.
Operation principle of the present invention is, liquid drops into upper seal pot 6 from the inlet opening 3.1 of upper tube box shell 3, through on the fluid apertures 6.1 that falls fall into lower seal pot 7, then fall into the object that each dry heat exchanger tube 5 reaches evaporation, concentrate through whereabouts fluid apertures 7.1 is dispersed; When the fluid flow of inlet opening 3.1 is large, a liquid part falls into lower seal pot 7 through the fluid apertures 6.1 that falls of seal pot 6, fall into lower seal pot 7 through overflow circle 8 after another part liquid overflows from seal pot 6, fall into each dry heat exchanger tube 5 by whereabouts fluid apertures 7.1 is dispersed.
