Detailed description of the invention
Fig. 1 shows the external structure schematic diagram of heat-exchanger rig of the present invention as shown in Figure 1, and Fig. 2 shows the partial sectional view of heat-exchanger rig of the present invention, and Fig. 3 shows schematic cross-section jacket structured in heat-exchanger rig of the present invention.The specific embodiment of heat-exchanger rig of the present invention is described in detail below in conjunction with Fig. 1, Fig. 2 and Fig. 3.
Heat-exchanger rig of the present invention comprises interior pipe 3 and chuck 4.Chuck 4 is enclosed within outside interior pipe 3, makes to form a heat transfer space 10 between chuck 4 and interior pipe 3.In heat transfer space 10, be provided with multiple playpipe 5.The sidewall of playpipe 5 offers spray-hole 5A, the quantity of spray-hole 5A can be determined as required.Preferably, in an embodiment as illustrated in figure 2, playpipe 5 is axially arranged in described heat transfer space 10, and the distance between playpipe 5 is evenly arranged, and the position of playpipe 5 contacts near chuck or with chuck 4.
Of course it is to be understood that the structure shown in Fig. 2 is only a preferred embodiment of playpipe 5 of the present invention.The present invention is not by the restriction of this concrete structure.In other embodiments, playpipe 5 also can be annularly arrange in heat transfer space 10, also can coil in a spiral manner in heat transfer space 10.
In the bottom of heat transfer space 10 utilizes, pipe 3 and chuck 4 form intake chamber 11, and intake chamber 11 is connected with the bottom of playpipe 5.Chuck 4 arranges water inlet 6, for supplying water to intake chamber 11 and playpipe 5.In the top of heat transfer space 10 utilizes, pipe 3 and chuck 4 form discharge chamber 12, and discharge chamber 12 is connected with heat transfer space 10.Chuck 4 is provided with gas outlet 8, discharges for the steam produced in heat transfer space 10.
Its operation principle of heat-exchanger rig as above is as follows: the lower end of heat-exchanger rig is connected with the carbonization chamber of coke oven, as the tedge of coke oven.The raw coke oven gas that carbonization chamber produces enters in interior pipe 3 from the lower end of heat-exchanger rig.Meanwhile, water source is provided by water inlet 6 to intake chamber 11 and playpipe 5.The water entering playpipe 5 sprays from the spray-hole 5A of playpipe 5, in heat transfer space 10, form the tiny globule or water smoke (arrow in Fig. 2 represents the injection direction of the globule or water smoke).High temperature raw coke oven gas in the globule in heat transfer space 10 and water smoke and interior pipe 3 carries out heat exchange, and the globule becomes water vapour with spray vaporization, and the temperature of raw coke oven gas constantly declines.The water vapour produced is discharged from by discharge chamber 12 and gas outlet 8, utilizes for follow-up equipment process.Raw coke oven gas after cooling is discharged from the upper end of interior pipe 3.
As mentioned above, in the present invention, in heat transfer space 10, water carries out heat exchange with the form of the tiny globule and water smoke and raw coke oven gas, and therefore, exchange efficiency is greatly improved.
In another embodiment, easily produce for solving tedge the problem that graphite accumulates and tar condenses, as shown in figures 1 and 3, heat-exchanger rig of the present invention can also comprise a disturbing flow device 9.This disturbing flow device 9 can be arranged on the top of interior pipe 3, also can be arranged on other position of interior pipe 3.The effect of disturbing flow device 9 is by the raw coke oven gas in pipe in disturbance 3, and the temperature between interior pipe 3 inside center and tube wall is kept evenly, thus prevents the generation of graphite accumulation and tar condensation phenomenon.In the present embodiment, disturbing flow device 9 can adopt the air blast parts of band blade construction, also can adopt other that gas can be made to produce the parts of disturbance.
In yet another embodiment of the present invention, heat-exchanger rig can also comprise muff 13, and muff 13 is arranged at outside chuck 4, as required between muff 13 and chuck 4, and can filling with insulation material.Can coated with sapphire (alundum (Al2O3) or aluminium oxide) protective layer on the inwall of interior pipe 3.
