Description
Technical field
This utility model relates to coke oven recuperation of heat structure, and particularly a kind of stopping production can overhaul the coal oven dithio-gas cement sensible heat recovery system of drum.
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, all arranges recuperation of heat structure on each coke oven coke oven uprising tube tube wall, so tedge is again a kind of heat exchanger, we are called for short it for tedge heat exchanger.
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 and utilizes a drum to carry out the system of centralized cycle recovery one permutation heat exchanger of riser of coke oven.It is formed by for water replanishing device, drum, circulating pump, several tedge heat exchangers, pipeline.For water replanishing device by tank, stock trough, form for small pump, from tank or stock trough, cold water is pumped into drum for water supplement port for small pump, drum outlet and a circulating pump connection, pump water to total feed pipe is diverted to each tedge heat exchanger, and each heat exchanger backwater confluxes and returns drum to total return pipe, backwater.
Above-mentioned recovery system has the disadvantage that on drum to be provided with many adnexaes, drum is also equipped with blowoff valve, relief valve, diffusion valve except being provided with and supplying water compensating valve, exhaust steam valve, outlet valve, back-water valve (BWV), drum inwall also can corrode in saline, if will entirety decommissioning so valve has when maintenance, drum self maintenance, annual annual test, just can overhaul one of them parts, affect coke oven whole system and produce.
Summary of the invention
This utility model purpose is for overcoming drawbacks described above, it is provided that a kind of stopping production can overhaul the coal oven dithio-gas cement sensible heat recovery system of drum.
This utility model scheme is: include for water replanishing device, drum, circulating pump, tedge heat exchanger, valve, pipeline, it is characterised in that: being provided with left and right drum, several tedge heat exchangers are divided in half into big group of left and right heat exchanger；Left drum outlet is connected with left circulating pump by a left outlet valve, left circulating pump discharge outlet is by each tedge heat exchanger water inlet pipeline connection of left water main Yu big group of left heat exchanger, each tedge heat exchanger outlet of big group of left heat exchanger all with left return main's pipeline connection, left return main, by left back-water valve (BWV) and left drum water return outlet pipeline connection, forms left recovery system；Right recovery system is same with left recovery system to be arranged；The right water intaking valve being respectively communicated with the left water intaking valve of left drum, right drum for small pump outlet by threeway for water replanishing device；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 utility model has the advantage of: both sides drum, drum adnexa can overhaul in rotation, and system does not stop production.
Accompanying drawing illustrates:
Accompanying drawing is this utility model structural representation.
Detailed description of the invention:
This utility model structure: include for water replanishing device, drum, circulating pump, several tedge heat exchanger 3, valve, pipelines, it is characterised in that: being provided with left and right drum, tedge heat exchanger 3 is divided in half into big group of left and right heat exchanger；Left drum 1 outlet is connected with left circulating pump 13 by a left outlet valve 11, left circulating pump 13 discharge outlet is by each tedge heat exchanger 3 water inlet pipeline connection of left water main 14 with big group of left heat exchanger, each tedge heat exchanger 3 outlet of big group of left heat exchanger all with left return main 15 pipeline connection, left return main 15, by left back-water valve (BWV) 12 and left drum 1 water return outlet pipeline connection, forms left recovery system；Right recovery system is same with left recovery system to be arranged；The small pump 6 that supplies for water replanishing device exports the right water intaking valve 26 being respectively communicated with the left water intaking valve 16 of left drum 1, right drum 2 by threeway；Left water main 14 concatenates connection with the right water main 24 of right recovery system by water supply communicating valve 9 pipeline, and left return main 15 concatenates connection with the right return main 25 of right recovery system by backwater communicating valve 8 pipeline.
Time properly functioning, close water supply communicating valve 9, backwater communicating valve 8, and when giving drum water delivery, then left water intaking valve 16, right water intaking valve 26 1 open a closedown.Left and right two recovery systems each become an internal recycle to run.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 tedge heat exchanger 3 of left recovery system relies on right drum 2 to carry out water circulation heat exchange.In like manner can overhaul right drum 2.
Left water main 14 supplies water to up to a hundred tedge heat exchangers 3, then to offer tens aperture siphunculus, one house steward supplies water to tens corresponding tedge heat exchangers 3, during tens aperture water outlets, then water main front end hydraulic pressure is big, drainage is many, but latter end aperture hydraulic pressure is low, water flow then ratio leading portion much less, water main's perforate is more many in a word, front and rear sections differential water pressures is more big, difference in flow also more big, heat transfer effect difference is also more big.For this, total feed pipe aperture number is reduced by double, reduces front and rear gaps saliva pressure reduction, improves back segment hydraulic pressure, flow.
Big group 5-8 tedge heat exchanger 3 of left heat exchanger forms a unit water supply group, namely in unit water supply group each tedge heat exchanger 3 water inlet first respectively with unit water inlet pipe 5 pipeline connection, unit water inlet pipe 5 water inlet again with left water inlet manifold 14 aperture pipeline connection；In unit water supply group each tedge heat exchanger 3 outlet first respectively with unit exit branch 4 pipeline connection, unit exit branch 4 outlet again with left return main 15 aperture pipeline connection；Big group of right heat exchanger is again provided with unit water-in and water-out manifold configuration.
