Abstract
The utility model provides a boiler drum water inlet and oxygen removal structure, which has the advantages of small floor area and reduced capital expenditure and operation cost. The boiler drum water inlet and oxygen removal structure comprises an oxygen removal head and a drum of which the bottom of the drum is provided with risers and down-comers, and is characterized in that the oxygen removal head is positioned above the drum, wherein partition plates are arranged at a central region in the drum; a cavity enclosed by the partition plates is specifically an oxygen removal water tank; the height of the partition plates is higher than the horizontal plane in the drum; the cess-pipe of the oxygen removal head is communicated with the oxygen removal water tank; the lower parts of the down-comers are connected with a transverse water pipe; the transverse water pipe penetrates through the partition plates and then extends to the two sides of the drum; the outer wall of the transverse water pipe is uniformly provided with water outlet holes; the upper part of the oxygen removal water tank is provided with evaporation devices; and steam pipes which are opposite to the oxygen removal head are arranged right above the evaporation devices.
Description
Technical field
The utility model relates to the technical field of boiler structure, is specially a kind of boiler-steam dome water inlet except oxide structure.
Background technology
The boiler feedwater deaeration plant is usually placed in the waste heat boiler drum layer, independently bear boiler feed water deoxygenation task, it is as relatively independent equipment, comprise deoxygenation head and deoxygenation water tank, floor space is bigger, also need dispose independently instrument, the setting that pipeline, pump, valve etc. are necessary, every capital cost and operating cost cost are all higher.
Summary of the invention
At the problems referred to above, the utility model provides a kind of boiler-steam dome water inlet except oxide structure, and its floor space is little, and capital cost and operating cost are reduced.
A kind of boiler-steam dome water inlet is except oxide structure, its technical scheme is such: it comprises the deoxygenation head, drum, the bottom of described drum is provided with tedge, down-comer, it is characterized in that: described deoxygenation head is positioned at the top of described drum, the inside center zone of described drum is provided with dividing plate, the inner chamber that described dividing plate surrounds is specially the deoxygenation water tank, the height of described dividing plate is higher than the horizontal plane in the described drum, the downcomer of described deoxygenation head is communicated with described deoxygenation water tank, the bottom of described downcomer is connected with the transverse row water distributor, described transverse row water distributor runs through the both sides that extend to described drum behind the described dividing plate, be evenly equipped with apopore on the outer wall of described horizontal water pipe, the top of described deoxygenation water tank is provided with vaporising device, and the top of described vaporising device faces the steam pipe of described deoxygenation head.
It is further characterized in that: the top of described dividing plate extends to 1/2 air space place in the described drum;
The length of described deoxygenation water tank is 2 meters ~ 3 meters.
After adopting structure of the present utility model, because the inside center zone of described drum is provided with dividing plate, the inner chamber that described dividing plate surrounds is specially the deoxygenation water tank, the height of described dividing plate is higher than the horizontal plane in the described drum, be that deoxygenation water tank and boiler-steam dome are integrated, the deoxygenation head is communicated with the deoxygenation water tank by steam pipe and downcomer, and it makes only need increase the drum volume inside as the deoxygenation water tank, its floor space is little, and capital cost and operating cost are reduced.
Description of drawings
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises deoxygenation 1, drum 5, the bottom of drum 5 is provided with tedge 8, down-comer 9, deoxygenation 1 is positioned at the top of drum 5, and the inside center zone of drum 5 is provided with dividing plate 6, and the inner chamber that dividing plate 6 surrounds is specially deoxygenation water tank 2, the length of deoxygenation water tank is 2 meters ~ 3 meters, the height of dividing plate 6 is higher than the horizontal plane 10 in the drum 5, and the top of dividing plate 6 extends to 1/2 air space place in the drum 5, and the lower seal of dividing plate 6 is to the bottom inside wall of drum 5.The downcomer 3 of deoxygenation 1 is communicated with deoxygenation water tanks 2, the bottom of downcomer 3 is connected with transverse row water distributor 11, transverse row water distributor 11 runs through the both sides that extend to drum 5 behind the dividing plate 6, be evenly equipped with apopore 12 on the outer wall of transverse row water distributor 11, the top of deoxygenation water tank 2 is provided with vaporising device 7, and the top of vaporising device 7 faces the steam pipe 4 of deoxygenation head.
Its operation principle is as follows: deoxygenation water inlet enters from water inlet 14, through the water inlet nozzle in the deoxygenation 1/or jet pipe/or alternate manner to water atomization/or membranization, again through the Steam Heating after vaporising device 7 evaporations to reach the deoxygenation purpose of deoxygenation water inlet.Water outlet after deoxygenation 1 deoxygenation feeds deoxygenation water tank 2 and boiler-steam dome 5 bottoms through downcomer 3, transverse row water distributor 11, the evaporimeter that enters boiler internal through the down-comer 9 of deoxygenation water tank 2 and boiler-steam dome 5 (does not draw among the figure again, belong to existing mature technology) carry out heat cycles, the water after the heating becomes gas-vapor mix and enters deoxygenation water tank 2 and boiler-steam dome 5 by tedge 8.Subsequently, the steam of a part of gas-vapor mix after deoxygenation water tank 2 separates by vaporising device 7 enters deoxygenation 1 a heating deoxygenation water inlet, forms oxygen removal process; Another part gas-vapor mix, is outwards steamed through steam (vapor) outlet 13 by after the multi-stage separation through boiler-steam dome 5 simultaneously, finishes the steam supply task.
