Abstract
The utility model proposes a kind of Turbo-charged Marine Boiler cascade type fume dust remover.Ten groups of dust removing units are arranged with dust excluding hood base, each dust removing units are made up of four gas wash towers, gas wash tower is cubic centrum thin-wall construction, laterally downward opening louvered fin is provided with the trapezoidal thin-walled of the cubic centrum of gas wash tower from top to bottom, external pipe parallel connection dust leg at the top of each gas wash tower, every five groups of dust legs are stretched out outside case after being connected with dedusting header.The utility model has the advantages that：By using Turbo-charged Marine Boiler cascade type fume dust remover; bulky grain in boiler smoke can be removed; avoiding the flue gas turbine expander of gas-turbine driven supercharger may be damaged or worn out by caused by the impact for the solia particle that fuel is carried under one's arms containing grey residue and combustion product in the process of running; the effectively running situation of protection gas-turbine driven supercharger; service life is improved, is favorably promoted the use of.
Description
Technical field：
Naval technology field is the utility model is related to, specifically a kind of Turbo-charged Marine Boiler cascade type flue gas ash removal
Device.
Background technology：
The compressor of gas-turbine driven supercharger is driven to be conveyed to boiler furnace using the waste heat driving smoke gas turbine of boiler smoke
The boiler of combustion-supporting compressed air is referred to as supercharged steam generator, and the supercharged steam generator difference maximum with conventional boiler is exactly burning and what is conducted heat adds
By force, the advantage brought is the reduction of steam steel quantity consumption per ton, so that boiler volume and weight greatly reduce, floor space is also small
Many, for the ship specific demand small to the in light weight of power set, size, supercharged steam generator can preferably meet；
The flue gas turbine expander of gas-turbine driven supercharger may be held under the arm by fuel containing grey residue and combustion product in the process of running
It is damaged or worn out caused by the impact of the solia particle of band.
Utility model content：
In order to avoid smoke gas turbine part is made by the particulate matter impact that boiler exhaust gas high speed flows in supercharged steam generator system
Into being damaged or worn out, the flue gas of boiler should take dust suppression, remove bulky grain thing that may be present in boiler exhaust gas, this practicality
A kind of new Turbo-charged Marine Boiler of offer cascade type fume dust remover.
The technical solution of the utility model is：A kind of Turbo-charged Marine Boiler cascade type fume dust remover, including dedusting
Cover base, ten groups of dust removing units is arranged with dust excluding hood base, each dust removing units are made up of four gas wash towers, gas wash tower
For the centrum thin-wall construction in four directions, laterally downward opening hundred are provided with from top to bottom on the trapezoidal thin-walled of the cubic centrum of gas wash tower
Leaf window fin, each gas wash tower top external pipe parallel connection dust leg, every five groups of dust legs stretch out cover after being connected with dedusting header
Outside shell.
The utility model has the advantages that：Filled by using the Turbo-charged Marine Boiler with cascade type flue gas ash removal
Put, the bulky grain in boiler smoke can be removed, avoid the flue gas turbine expander of gas-turbine driven supercharger from the process of running may
It is damaged or worn out by caused by the impact for the solia particle that fuel is carried under one's arms containing grey residue and combustion product, effectively protects turbine
The running situation of unit is pressurized, service life is improved, favorably promotes the use of.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Accompanying drawing 2 is the top view of accompanying drawing 1；
Accompanying drawing 3 is dust removing units structure chart in the utility model；
Accompanying drawing 4 is the structure chart of gas wash tower in the utility model；
Accompanying drawing 5 is the top view of accompanying drawing 4.
1- dust excluding hoods base in figure, 2- dust removing units, 3- cases, 4- dedusting headers, 5- dust legs, 6- gas wash towers, 7- hundred
Leaf window fin.
Embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Fig. 1 combinations Fig. 2~5, a kind of Turbo-charged Marine Boiler cascade type fume dust remover, including dust excluding hood bottom
Seat 1, ten groups of dust removing units 2 is arranged with dust excluding hood base 1, each dust removing units 2 are made up of four gas wash towers 6, dedusting
Tower 6 is cubic centrum thin-wall construction, is laterally provided with from top to bottom on the trapezoidal thin-walled of the cubic centrum of gas wash tower 6 opening down
Louvered fin 7, each top external pipe parallel connection dust leg 5 of gas wash tower 6, every five groups of dust legs 5 are connected with dedusting header 4
Stretch out afterwards outside case 3.
This device is mountable in supercharged steam generator afterbody discharge flue, to remove the particulate matter in boiler exhaust gas.
Such a device works according to venetian blind type inertia grid principle, and boiler smoke flows through big in flue gas stream after this device
Granular solids particle is because inertia is big, before and after being captured by gas wash tower 6 and being finally pooled to by the dust leg 5 of dust arrester
The flue gas ash removal header 4 at both ends is discharged, and the flue gas for discharging bulky grain is discharged after louvered fin flows downward into case.
By using Turbo-charged Marine Boiler cascade type fume dust remover, the bulky grain in boiler smoke can be removed
Go, avoid the flue gas turbine expander of gas-turbine driven supercharger from being carried under one's arms in the process of running by fuel containing grey residue and combustion product
Solia particle impact caused by be damaged or worn out, effectively protect gas-turbine driven supercharger running situation, raising use the longevity
Life, is favorably promoted the use of.
