Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of unitized exchanger, it includes housing 1, described housing 1 is respectively arranged at two ends with the first bobbin carriage end socket the 2, first heat exchanger tube 3 and second bobbin carriage end socket the 4, second heat exchanger tube 5, the two ends of described first heat exchanger tube 3 connect with the first cold stream outlet 7 with the first cold logistics import 6 being located on described first bobbin carriage end socket 2 respectively, and the two ends of described second heat exchanger tube 5 connect with the second cold stream outlet 9 with the second cold logistics import 8 being located on described second bobbin carriage end socket 4 respectively；Wherein for strengthening heat transfer, improving heat transfer efficiency, the surrounding at described first heat exchanger tube 3 and the second heat exchanger tube 5 is distributed deflection plate 10 respectively, and described deflection plate 10 is interspersed and is fixed on the inwall of described housing 1；The two ends of the most described housing 1 are additionally provided with the charging mouth of pipe 11 and the discharging mouth of pipe 12 at the first bobbin carriage end socket 2 and the second bobbin carriage end socket 4, and the described charging mouth of pipe 11 is positioned at above housing, and the described discharging mouth of pipe 12 is positioned at below housing.
Housing 1 of the present utility model cylindrically, is connected by flange is detachable between the two ends of housing 1 with described first bobbin carriage end socket 2 and described second bobbin carriage end socket 4；And the first heat exchanger tube 3 and the second heat exchanger tube 5 are U heat exchange.This unitized exchanger can realize three strands of materials simultaneously and carry out energy transmission under two kinds of different operating operating modes simultaneously；If the shell side flowing through this unitized exchanger is high temperature fluid, then flowing through two tube sides is cold flow body, and the medium kind of cold flow body, operation operating mode (temperature, pressure, flow etc.) can be different, and vice versa；This unitized exchanger is applicable between gas-liquid, gas gas, gas vapour or liquid liquid the heat exchange operation carried out.
Work process of the present utility model is: high-temperature heat flux stock enters shell side from the charging mouth of pipe 11, after logistics heat exchange cold with first strand in the first heat exchanger tube 3, then logistics heat exchange cold with second strand in the second heat exchanger tube 5, then discharge from the discharging mouth of pipe 12；First burst of cold logistics enters the first bobbin carriage end socket 2 from the first cold logistics import 6, flows through the first heat exchanger tube 3, discharges from the first cold stream outlet 7 after being heated；Second burst of cold logistics enters the second bobbin carriage end socket 4 from the second cold logistics import 8, flows through the second heat exchanger tube 5, and heated rear second cold stream outlet 9 is discharged.As a example by high temperature shift gas heating low-pressure steam and raw gas, detailed process is as follows: 22400Nm3/ h conversion gas (3.8MPa, 430 DEG C) by charging the mouth of pipe 11 enter shell side, after 30000kg/h low-pressure steam in the first heat exchanger tube 3 (1.1MPa, 200 DEG C) heat exchange, then with the 17920Nm in the second heat exchanger tube 53After/h raw gas (3.8MPa, 216 DEG C) heat exchange is cooled to 387 DEG C, discharge from the discharging mouth of pipe 12.30000kg/h low-pressure steam (1.1MPa, 200 DEG C) enters the first bobbin carriage end socket 2 from the first cold logistics import 6, flows through the first heat exchanger tube 3, after being heated to 260 DEG C, discharges from the first cold stream outlet 7；17920Nm3/ h raw gas (3.8MPa, 216 DEG C) enters the second bobbin carriage end socket 4 from the second cold logistics import 8, flows through the second heat exchanger tube 5, after being heated to 280 DEG C, discharges from the second cold stream outlet 9.First burst of hot logistics and second burst of cold logistics are heated by the unitized exchanger of this utility model design by one high-temperature heat flux stock simultaneously, it is achieved that the heat transfer operations under two kinds of different operating modes, and compact conformation is easy and simple to handle, invests low.
The principle that the invention is simply described described in above-described embodiment and description; the most therefore protection domain of the present utility model is limited; on the premise of without departing from the invention spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model is not directed to part and the most same as the prior art prior art maybe can be used to be realized.
