Abstract
The utility model discloses a waste heat utilizing device for an ascending pipe of a turbulence type coke oven, solving the problems in the existing waste heat utilizing device for the ascending pipe of the coke oven that the device has small heat exchange area and uneven heat exchange, and the circulating water can have short circuit easily. The device comprises an annular cavity which consists of an outer barrel and an inner barrel, a water inlet and a steam outlet are arranged at two ends of the annular cavity respectively, spoilers are arranged longitudinally in the annular cavity in a layering way, the spoilers are connected to walls of the outer barrel and the inner barrel, and circulating water exchanges heat in interlayers among the spoilers layer by layer. The waste heat utilizing device avoids problems of short circuit of circulating water and deformation and leakage by stress caused by uneven heat exchange and the like; and the heat exchange area of the circulating area is arranged reasonably, the heat exchange efficiency is high and the pressure of the generated steam is high.
Description
Technical field
The utility model relates to a kind of coke oven residual heat using device, relates in particular to a kind of disturbed flow type coke oven coke oven uprising tube residual heat using device.
Background technology
Come out to enter about 800 ℃ of the raw gas of upcast from coke furnace carbonization chamber, coal chemical enterprise generally adopts traditional ammoniacal liquor spray pattern cooling, and a large amount of residual heat resources can't obtain utilizing.The eighties in last century, some enterprises adopt the Ascension Pipe Gasification refrigerating unit to reclaim heat, and this device is formed water jacket by urceolus and inner core, and corresponding water-in, the steam outlet of being provided with.This device exists that heat interchanging area is little, heat exchange is inhomogeneous, the easy problem of short-circuit of recirculated water, and the inequality of being heated also can produce stress, causes this device distortion, leaks, and can't use.
The utility model content
The purpose of this utility model is to overcome the prior art defective, provides a kind of and can increase heat interchanging area, prevents the disturbed flow type coke oven coke oven uprising tube residual heat using device of recirculated water short circuit.
The technical solution of the utility model is achieved in that disturbed flow type coke oven coke oven uprising tube residual heat using device, form annular cavity by urceolus and inner core, the vertical two ends of annular cavity are provided with water-in and steam outlet, it is, longitudinally layering is provided with interceptor in annular cavity, interceptor is connected on urceolus and the inner tube wall, and recirculated water is heat exchange successively between the interceptor interlayer.
Preferably, described interceptor is provided with the current breach, and the current breach is interspersed.
The utility model characteristics are as follows.
When 1, working, raw gas enters in the upcast from the upcast bottom, by the thermal conduction heat exchange with the heat transferred inner core, pass to the recirculated water between the inner/outer tube again, because layering longitudinally is provided with interceptor in annular cavity, recirculated water is heat exchange successively between the interceptor interlayer, partly or entirely vaporization, enter drum from steam outlet, realize heat recovery.
2, under the guiding of interceptor, the recirculated water of heat exchange evenly flows in annular cavity, problems such as the distortion that avoided the recirculated water short circuit, the uneven generation stress that is heated causes, leakage.
3, the utility model heat interchanging area distributes rationally, the heat exchange efficiency height, and the pressure height steams.

Fig. 2 is that inner core launches synoptic diagram.
Among the figure, the 1-urceolus; The 2-inner core; The 3-upcast; The 4-water-in; The 5-steam outlet; The 6-interceptor.
Embodiment
Be further described below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, disturbed flow type coke oven coke oven uprising tube residual heat using device, the annular cavity of being made up of urceolus 1 and inner core 2 is enclosed in upcast 3 outsides, the vertical two ends of annular cavity are provided with water-in 4 and steam outlet 5, layering longitudinally is provided with interceptor 6 in annular cavity, and interceptor is connected on urceolus 1 and inner core 2 walls, and each layer interceptor 6 established a current breach, interceptor 6 current breach are interspersed, recirculated water heat exchange successively between interceptor 6 interlayers.
During work, raw gas enters in the upcast 3 from upcast 3 bottoms, by the thermal conduction heat exchange with heat transferred inner core 2, pass to the recirculated water between the inner/outer tube again, because layering longitudinally is provided with interceptor 6, recirculated water heat exchange successively between interceptor 6 interlayers in annular cavity, problems such as the distortion that avoided the recirculated water short circuit, the uneven generation stress that is heated causes, leakage, recirculated water enters drum from steam outlet after partly or entirely vaporizing, and realizes heat recovery.
