Abstract
The utility model discloses a retrieve equipment of tedge waste heat, including upper portion tedge, tedge tube cap, bridge tube and discharge, bridge tube one end and bridge tube flange joint, the other end is connected with the discharge, still includes annular casing, and annular casing setting is between upper portion tedge and tedge tube cap, and annular casing passes through the bridge tube flange to be connected with the bridge tube, the annular housing face annular tubulation that distributes, and annular tubulation is connected with the steam pocket, and annular casing is " eight " font and describes. The high temperature raw coke oven gas gets into the internal portion of circular casing by the upper portion tedge, upwards flow to top back -porch annular shells inner wall downwards to bridge tube department because the effect of aqueous ammonia spray line, the negative pressure sucks in the discharge, flow the in -process raw coke oven gas through annular casing and annular tubulation heat transfer, annular tubulation is heat transfer to steam pocket, byproduct steam or hot water, make full use of the high temperature raw coke oven gas, the while has still avoided appearing heat pipe booster, the overheated coking scheduling problem of conduction oil.
Description
Technical field
The utility model relates to a kind of waste heat recovery apparatus, is specifically related to a kind of equipment reclaiming tedge waste heat.
Background technology
In recent years along with the lasting propelling to the work of coking industry energy-saving consumption reduction, the energy waste how solved in production process also more and more obtains the attention of people.Coke enterprise is since use carbonizing chamber method fires coke, and in tedge, the waste heat of high temperature coke oven raw coke oven gas just fails effectively to utilize always, with cyclic ammonia water cooling, heat can only be wasted.Someone is by the processing medium water heat exchange in raw coke oven gas and chuck, but occurs heat-transfer surface bonding tar, floccule blockage problem, and after heat-transfer surface damages, in chuck, processing medium water leaks and affects coke production into carbonizing chamber.In recent years, hot pipe technique and conduction oil technology is adopted to carry out waste heat of coke oven crude gas utilization, all can not long-period stable operation, main cause is: these technology all do not overcome the difficulty of coke-stove gas heat exchange, when heat-exchange system other parts fault quits work, carbonizing chamber method, an oven coke has not been produced, can not blowing out within the short time of midway, so there is the problem such as heat pipe booster, the overheated coking of conduction oil.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of equipment reclaiming tedge waste heat, takes full advantage of high temperature raw coke oven gas, also avoid simultaneously and occurs the problem such as heat pipe booster, the overheated coking of conduction oil.
To achieve these goals, the technical solution adopted in the utility model is: a kind of equipment reclaiming tedge waste heat, comprise top tedge, tedge pipe lid, bridge tube and discharge, bridge tube one end and bridge tube Flange joint, the other end is connected with discharge, also comprise toroidal shell, toroidal shell is arranged between top tedge and tedge pipe lid, toroidal shell is connected with bridge tube by bridge tube flange, toroidal shell surface distributed annular tubulation, annular tubulation is connected with drum, and toroidal shell is "eight" shape shape.
Further, toroidal shell is constantly expanded by top-to-bottom caliber, and bottom tilts to bridge tube closure.
Further, annular tubulation adopts built-up welding mode to be connected with toroidal shell.
The beneficial effects of the utility model are: high temperature raw coke oven gas enters toroidal shell inside by top tedge, travel up to behind top that annularly inner walls is down to bridge tube place, and due to the effect of ammoniacal liquor spray line, negative pressure sucks in discharge; In flow process, raw coke oven gas is by toroidal shell and annular tubulation heat exchange, and heat is passed to drum by annular tubulation, byproduct steam or hot water, takes full advantage of high temperature raw coke oven gas, also avoid simultaneously and occurs the problem such as heat pipe booster, the overheated coking of conduction oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, drum, 2, tedge pipe lid, 3, toroidal shell, 4, annular tubulation, 5, bridge tube flange, 6, bridge tube, 7, top tedge, 8, discharge, 9, ammoniacal liquor spray line.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the equipment of this recovery tedge waste heat, comprise top tedge 7, tedge pipe lid 2, bridge tube 6 and discharge 8, bridge tube 6 one end is connected with bridge tube flange 5, the other end is connected with discharge 8, also comprise toroidal shell 3, toroidal shell 3 is arranged between top tedge 7 and tedge pipe lid 2, toroidal shell 3 is connected with bridge tube 6 by bridge tube flange 5, toroidal shell 3 surface distributed annular tubulation 4, annular tubulation 4 is connected with drum 1, toroidal shell 3 is "eight" shape shape, heat exchange area in toroidal shell 3 can be increased, toroidal shell 3 is constantly expanded by top-to-bottom caliber, bottom tilts to bridge tube 6 closure, attachment tar graphite is trickled along inwall.In order to improve the utility model performance, annular tubulation 4 adopts built-up welding mode to be connected with toroidal shell 3.
During work, it is inner that high temperature raw coke oven gas enters toroidal shell 3 by top tedge 7, travels up to behind top that annularly housing 3 inwall is down to bridge tube 6 place, and because ammoniacal liquor spray line 9 acts on, negative pressure sucks in discharge 8.In flow process, raw coke oven gas is by toroidal shell 3 and the heat exchange of annular tubulation 4, and heat is passed to drum 1 by annular tubulation 4, byproduct steam or hot water.
