Description
Technical field
The coal oven dithio-gas cement sensible heat recovery system of drum can be overhauled the present invention relates to coke oven recuperation of heat structure, particularly a kind of stopping production.
Background technology
Coking by coke oven is up to a hundred coke oven coking arranged side by side, and coke oven upper end is provided with raw coke oven gas tedge, for UTILIZATION OF VESIDUAL HEAT IN, recuperation of heat structure is set all on each coke oven coke oven uprising tube tube wall, so tedge is again a kind of heat exchanger, we referred to as it be rising heat exchange of heat pipe.
Chinese patent 201310391429.3 " a kind of raw coke over gas riser heat-exchanger rig " discloses a kind of tedge heat exchanger structure form.Chinese patent 201420483043.5 " a kind of raw coke over gas riser residual neat recovering system " discloses the system that one permutation heat exchanger of riser of coke oven is carried out into centralized cycle recovery using a drum.It is constituted by for water replanishing device, drum, circulating pump, several rising heats exchange of heat pipe, pipeline.Constituted by tank, stock trough, for small pump for water replanishing device, cold water is pumped into drum from tank or stock trough for small pump and supplies water supplement port, drum delivery port is connected with a circulating pump, pump water to total feed pipe is diverted to each rising heat exchange of heat pipe, and each heat exchanger backwater to conflux and return to drum to total return pipe, backwater.
Above-mentioned recovery system has a drawback in that：Many annexes are installed on drum, blowoff valve, safety valve, diffusion valve are also equipped with drum in addition to being provided with for water compensating valve, exhaust steam valve, outlet valve, back-water valve (BWV), drum inwall can also corrode in salt solution, if so valve will integrally decommission when having maintenance, drum itself maintenance, annual annual test, one of part, the whole system production of influence coke oven can just be overhauled.
The content of the invention
The object of the invention is to overcome drawbacks described above, there is provided a kind of stopping production can overhaul the coal oven dithio-gas cement sensible heat recovery system of drum.
The present invention program is：Including for water replanishing device, drum, circulating pump, rising heat exchange of heat pipe, valve, pipeline, it is characterised in that：Left and right drum is provided with, several rise heat exchange of heat pipe and are divided in half into big group of left and right heat exchanger；Left drum delivery port is connected by a left outlet valve with left circulating pump, each rising heat exchange of heat pipe water inlet pipeline connection that left circulating pump discharge outlet passes through big group of left water main and left heat exchanger, each rising heat exchange of heat pipe delivery port of big group of left heat exchanger all with left return main's pipeline connection, left return main constitutes left recovery system by left back-water valve (BWV) and left drum water return outlet pipeline connection；Right recovery system is same with left recovery system to be set；Confession moisturizing pump discharge for water replanishing device is respectively communicated with the right water intaking valve of the left water intaking valve of left drum, right drum by threeway；Left water main concatenates connection with the right water main of right recovery system by a water supply communicating valve pipeline, and left return main concatenates connection with the right return main of right recovery system by a backwater communicating valve pipeline.
The advantage of the invention is that：Both sides drum, drum annex can rotation maintenance, system do not stop production.
Brief description of the drawings：
Accompanying drawing is schematic structural view of the invention.
Specific embodiment：
Structure of the present invention：Including for water replanishing device, drum, circulating pump, rising heat exchange of heat pipe 3, valve, pipeline, it is characterised in that：Left and right drum is provided with, several rise heat exchange of heat pipe 3 and are divided in half into big group of left and right heat exchanger；The delivery port of left drum 1 is connected by a left outlet valve 11 with left circulating pump 13, the water inlet pipeline connection of each rising heat exchange of heat pipe 3 that the discharge outlet of left circulating pump 13 passes through big group of left water main 14 and left heat exchanger, each delivery port of rising heat exchange of heat pipe 3 of big group of left heat exchanger all with the pipeline connection of left return main 15, left return main 15 constitutes left recovery system by left back-water valve (BWV) 12 and the water return outlet pipeline connection of left drum 1；Right recovery system is same with left recovery system to be set；Confession small pump 6 for water replanishing device exports the right water intaking valve 26 that the left water intaking valve 16 of left drum 1, right drum 2 are respectively communicated with by threeway；Left water main 14 concatenates connection with the right water main 24 of right recovery system by a pipeline of water supply communicating valve 9, and left return main 15 concatenates connection with the right return main 25 of right recovery system by a pipeline of backwater communicating valve 8.
During normal operation, water supply communicating valve 9, backwater communicating valve 8 is closed, and when giving drum water delivery, then left water intaking valve 16, right water intaking valve 26 1 open a closing.Left and right two recovery systems are each into an interior circulation operation.To maintenance or the left drum 1 of annual test, then close left water intaking valve 16, left outlet valve 11, left back-water valve (BWV) 12, open water supply communicating valve 9, backwater communicating valve 8, left water main 14 connects water supply with right water main 24, left return main 15 connects water supply with right return main 25, and the rising heat exchange of heat pipe 3 of left recovery system carries out water circulation heat exchange by right drum 2.Right drum 2 can similarly be overhauled.
Left water main 14 supplies water to up to a hundred rising heats exchange of heat pipe 3, then to open up tens aperture siphunculus, one house steward supplies water to corresponding tens rising heats exchange of heat pipe 3, then water main front end hydraulic pressure is big during tens aperture water outlets, drainage is more, but latter end aperture hydraulic pressure is low, water flow is then than leading portion much less, water main's perforate is more in a word, and front and rear sections differential water pressures are bigger, difference in flow is also bigger, heat transfer effect difference is also bigger.For this, we reduce total feed pipe aperture number at double, reduce front and rear gaps saliva pressure difference, improve back segment hydraulic pressure, flow.
Big group of 5-8 rising heat exchange of heat pipe 3 of left heat exchanger constitutes a unit water supply group, i.e. in unit water supply group it is each rise the water inlet of heat exchange of heat pipe 3 first respectively with the pipeline connection of unit water inlet pipe 5, the water inlet of unit water inlet pipe 5 again with the aperture pipeline connection of left water inlet manifold 14；In unit water supply group it is each rise the delivery port of heat exchange of heat pipe 3 first respectively with the pipeline connection of unit exit branch 4, the delivery port of unit exit branch 4 again with the aperture pipeline connection of left return main 15；Big group of right heat exchanger is again provided with unit water-in and water-out manifold configuration.
