Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The technical solution of the utility model is described in further detail with specific embodiment.
Fig. 1 to Fig. 2 is please referred to, Fig. 1 is that integrated fume dedusting denitrification apparatus provided by the utility model is a kind of specific
The main view of embodiment；Fig. 2 is the schematic internal view of sub-air chamber under Fig. 1 left view visual angle.
The integrated fume dedusting denitrification apparatus, including multiple sub-air chamber 1 (six are shown in figure), each sub-air chamber 1 be in front of,
Two rows of afterwards to arrange, each sub-air chamber 1 in every row arranges in left-right direction.
Moreover, forming clearance space between two rows, partition 4 is set, the lower section of partition 4 forms air inlet cigarette in the clearance space
Road 2, top forms exhaust uptake 3, and the opposite right side in 4 left side of partition tilts upwards, makes inlet air stack 2 and exhaust uptake 3
It is wedge-shaped flue.
Moreover, each sub-air chamber 1 is respectively the area Jing Qi 1a, dedusting denitration region 1b and ash bucket area 1c from top to bottom.
Wherein, card 5, ceramic filter drum 6 and the blowing part 7 for deashing are provided in dedusting denitration region 1b.Blowing portion
Part 7 is located at the top of card 5, and card 5 is equipped with mounting hole, and the upper end of each ceramic filter drum 6 is equipped with each installation correspondingly
Hole.The outer surface of the ceramic filter drum 6 is equipped with filter membrane, and inner surface is attached with denitrating catalyst, and flue gas is first under the action of blower
The outer surface for flowing through ceramic filter drum 6 removes the dust in flue gas under the action of filter membrane, passes through the interior table of ceramic filter drum 6
The nitrogen oxides removed in flue gas is reacted in face under the action of denitrating catalyst with the ammonia being previously implanted into.
Moreover, each area Jing Qi 1a is equipped with the first air door 8 close to the side wall of exhaust uptake 3, neat stress is through 8 row of the first air door
Out into exhaust uptake 3.Moreover, each area Jing Qi 1a is equipped with the first maintenance door 9 far from the side wall of exhaust uptake 3.
Moreover, each ash bucket area 1c is separated with inlet air stack 2 using horizontal wall s, and each horizontal wall s is equipped with the second air door
10, after inlet air stack flue gas enters ash bucket area by the second air door, ceramic filter drum dedusting denitration region 1b is passed through via ash bucket area.And
And it is provided with airflow-distribution board 15 in each ash bucket area 1c, for guiding flue gas, it is ensured that stream when flue gas enters dedusting denitration region 1b
Speed is stablized, is evenly distributed.
Preferably, the first air door 8 and the second air door 10 are electric flap, to realize the long-range control to the two.
It, can be remotely by the sub-air chamber 1 corresponding first when some sub-air chamber 1 occurs that ceramic filter drum is broken to be needed to overhaul
Air door 8 and the second air door 10 are closed, and the sub-air chamber 1 is isolated.Later, corresponding first maintenance door 9 of sub-air chamber 1 is opened, into
After row appropriateness cooling, maintenance personal wears protective garment and enters in air-purifying chamber from the first maintenance door 9, carries out to broken ceramic filter drum
Replacement.In replacement process, other sub-air chamber 1 are still in normal operating conditions, without stopping work, it is thus achieved that on-bne repair.
Further, nearby detector can be set in each first air door 8, for detecting flue gas concentration.It, can be with when maintenance
The flue gas concentration arrived by comparing each detector test, quickly judgement is that the ceramic filter drum of which sub-air chamber 1 occurs being crushed (out
The broken corresponding flue gas concentration of sub-air chamber 1 of existing ceramic filter drum is higher), so as to quickly locate Awaiting Overhaul position, make to examine
Duration is repaired to effectively shorten.
Further, in each area Jing Qi 1a close to card 5 position be equipped with trample floor 11, specifically include braced frame and
Several pieces of pedals, braced frame can be fixed on the shell wall of the area Jing Qi 1a by modes such as welding, grafting, and pedal is detachable
Ground is laid in braced frame.Moreover, the piecemeal position and position of opening of the piecemeal position of pedal and position of opening and card 5
Unanimously, so as to the replacement operation of ceramic filter drum.Service personnel tramples on trampling layer 11, can evade and directly trample the cause of card 5
The risk for damaging card 5 or ceramic filter drum 6.
Further, thermal insulation layer 14 can be set in the shell wall inner surface of each area Jing Qi 1a, on the one hand can protect maintenance
Personnel safety avoids personnel from scalding；On the other hand it can shorten temperature fall time, to further shorten maintenance duration.
Further, baffle 12 can be set in each ash bucket area 1c, baffle 12 can be solid by modes such as welding, grafting
It is scheduled on the shell wall of ash bucket area 1c.Meanwhile the second maintenance door can be set far from the side wall of inlet air stack 2 in each ash bucket area 1c
13。
Baffle 12 is used to accept the fragment of ceramic filter drum 6, and the fragment that ceramic filter drum 6 can be evaded by the way that baffle 12 is arranged sinks
The risk that product causes ash bucket area 1c to block in the ash bucket area bottom 1c.Specifically, baffle 12 is equipped with several through-holes.Preferably,
Each through-hole is staggeredly arranged with the mounting hole on card 5, so that ash material can pass through through-hole and fall into the ash bucket area bottom 1c when deashing
Play the role of intercepting fragment simultaneously.Preferably, the pore diameter range of through-hole is 100mm-300mm.
When maintenance, after having replaced broken ceramic filter drum 6, the second maintenance door 13 is opened, after appropriateness cooling, maintenance personal is worn
Protective garment through the second maintenance door 13 enter ash bucket area 1c in, it is broken to will fall off the ceramic filter drum on baffle 12 using specific purpose tool
Block picking, cleaning falls.Under normal circumstances, when replacing ceramic filter drum 6, the second maintenance door 13 should be kept to close, clears up ceramic filter drum 6
When fragment, the first maintenance door 9 should be kept to close, to reduce air-flow flowing, operation convenient to overhaul.
Further, rapping component (not shown) is set in each ash bucket area 1c, is used for rapping baffle 12.It is preferred that
, rapping component is electronic rapping component, so as to its long-range control.
When maintenance, after the complete ceramic filter drum fragment of picking, cleaning, it can make to accumulate on baffle 12 with remote opening rapping component
Ash material fall into the ash bucket area bottom 1c, to avoid the blocking of baffle 12.
Further, thermal insulation layer 14 also can be set in the shell wall inner surface of each ash bucket area 1c, on the one hand, can protect inspection
Personnel safety is repaired, personnel is avoided to scald, on the other hand can save temperature fall time, so as to shorten maintenance duration.Preferably, each
Only thermal insulation layer 14 is arranged in the shell wall inner surface above baffle 12 to ash bucket area 1c.
After the completion of maintenance, opens the first air door 8, the second air door 10, closes the first maintenance door 9, the second maintenance door 13, flue gas
Each sub-air chamber's ash bucket area 1c successively is flowed into through inlet air stack 2, the second air door 10, enters 1b via 15 water conservancy diversion of airflow-distribution board and carries out
Dedusting denitration, the neat stress generated later are successively expelled in atmosphere through the first air door 8, exhaust uptake 3 via air-purifying chamber 1a.
Above to it is provided by the utility model can the integrated fume dedusting denitrification apparatus of on-bne repair carried out in detail
It introduces.Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments
