Abstract
The invention relates to a heat exchanger of a riser of a coke oven. The heat exchanger comprises a cylindrical heat exchanger body, an upper flue flange (1) and a lower flue flange (2) are arranged on the heat exchanger body, a plurality of annular heat exchange pipes (3) are vertically arranged on the side wall of the heat exchanger body, and a water jacket (4) is disposed on a side of each annular heat exchange pipe (3). The annular heat exchange pipes (3) are arrayed cylindrically. The heat exchanger is in contact with flue gas via the annular heat exchange pipes (3), and water in a waste heat system is filled in the water jackets (4). When a single heat exchange pipe is damaged to cause leakage, only the water in the single heat exchange pipe leaks without affecting production due to the fact that the quantity of the water in the single heat exchange pipe is quite low, damage to equipment of the coke oven is avoided, safety and stability of the waste heat system can be guaranteed fundamentally, and influence to production of the coke oven is prevented.
Description
Technical field
The present invention relates to the heat exchange field, relate in particular to a kind of coke oven coke oven uprising tube heat exchanger.
Background technology
At present, the existing coke oven coke oven uprising tube overwhelming majority does not all have residual neat recovering system, and a large amount of heats fall through spraying into the ammoniacal liquor cooling loss.The various tedge raw coke oven gas residual neat recovering systems of research and development reclaim raw coke oven gas waste heat major part and all are used to produce low-pressure saturated steam at present, and technology is immature, has problems, and it can not large-scale industrialization promotion be used.The coking of raw coke oven gas tar steam makes the tedge heat exchanger be difficult to permanent stable operation always in the coke oven coke oven uprising tube.Especially waste heat system long-time running weld cracking, the waste heat system entering carbonizing chamber of coke oven that leaks in a large number, influence is produced or is damaged coking furnace shaft, causes big loss.
At present people's raw coke oven gas tedge waste heat The Application of Technology has two kinds of animus, a kind ofly thinks technical feasibility, advocates actively to apply; A kind of in addition dissenting thinks that technology is unreliable, and the waste heat system can threaten the coke oven safety in production.This shows that the security of waste heat system becomes the technical bottleneck that waste heat of coke oven crude gas utilizes.
Summary of the invention
The technical problem that the present invention solves is the operation steady in a long-term of a kind of ability of design, and does not influence the coke oven coke oven uprising tube heat exchanger that coke oven is produced.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of coke oven coke oven uprising tube annular heat pipe heat exchanger; Comprise the cylindricality heat exchanger body; Establish import and outlet on the said heat exchanger body, it is characterized in that: described heat exchanger body sidewall is vertically established a plurality of annular heat exchanger tubes, and described annular heat exchanger tube one sidepiece is established water leg.
First preferred version of the present invention is that described import is the flue lower flange.
Second preferred version of the present invention is that described outlet is the flue upper flange.
The 3rd preferred version of the present invention is that described a plurality of annular heat exchanger tubes are arranged cylindrical.
Technical advantage of the present invention is:
1, breaks through the limitation (such as being prone to coking because of directly contacting, washing away potential safety hazards such as violent) that in the past heat exchanger is arranged in tedge inside with coal gas; Give full play to the built-in advantage of heat exchanger (bigger such as the coefficient of heat transfer), the characteristics of utilizing single heat pipe to damage the operation of not influence system are avoided its potential safety hazard.
2, adopt annular heat pipe as heat exchanger, and heat pipe is a kind of superconduct heat transmission equipment, better than the heat exchange property of conventional pipe heat exchanger.
3, do not influence the original operating procedure of coke oven, the entering carbonization chamber of can effectively avoiding leaking in a large number; But safe and stable operation, single heat pipe damages can guarantee that still system normally moves.Adopt heat pipe heat exchanging, heat exchange property is better than conventional heat exchanger.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is the vertical view of Fig. 1.
In the accompanying drawing: 1 is that flue lower flange, 2 is that flue upper flange, 3 is that annular heat pipe, 4 is that water leg, 5 is that upper header, 6 is that lower collecting box, 7 is that water inlet, 8 is a delivery port.
The specific embodiment
Below in conjunction with specific embodiment invention is further specified.
Coke oven coke oven uprising tube annular heat pipe heat exchanger, the cylindricality heat exchanger body is established flue lower flange 1 and flue upper flange 2 on the said heat exchanger body, and the heat exchanger body sidewall is vertically established a plurality of annular heat exchanger tubes 3, and annular heat exchanger tube 3 one sidepieces are established water leg 4.A plurality of annular heat exchanger tubes 3 are arranged cylindrical.
Coal oven dithio-gas gets into from flue lower flange 1; Flow out from flue upper flange 2; In this process, wash away annular heat pipe 3 and carry out exchange heat; Add the feedwater among the hot water jacket 4 after annular heat pipe 3 heat absorptions, and the feedwater in the water leg 4 is to be got into by water inlet 7 and lower collecting box 6, and flows out from upper header 5 and delivery port 8.
What this annular heat pipe heat exchanger contacted with flue gas is annular heat pipe 3, and the intrasystem water level of waste heat leaks when heat pipe damages in water leg 4; It is the water leakage in the single heat pipe; Because the water yield in the single heat pipe seldom, leaking can not influence production, more can not cause damage to coke oven for iron; Can guarantee the security and stability of waste heat system from root, can not impact coke oven production.
The invention is not restricted to above embodiment, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
Claims (4)
1. coke oven coke oven uprising tube annular heat pipe heat exchanger; Comprise the cylindricality heat exchanger body; Establish import and outlet on the said heat exchanger body, it is characterized in that: described heat exchanger body sidewall is vertically established a plurality of annular heat exchanger tubes, and described annular heat exchanger tube one sidepiece is established water leg.
