Description
Technical field
The utility model relates to a kind of biomass boiler dust pelletizing systems that anticorrosion is leaked out, and belong to biomass electric power plant dedusting and set
Standby technical field.
Background technique
In the prior art, the tail flue gas of boiler gathers dust via the long bag low-pressure dust trap of tradition, and there are the following problems：
The case where long bag low-pressure dust trap of tradition changes bag due to considering dust remover roof, is arranged above dust catcher gas purifying chamber
During deduster operation and maintenance air leakage phenomena, and manhole cover inevitably occur for the cover plate for manhole of large area at cover plate for manhole
A possibility that area of plate is bigger, leaks out is higher.It leaks out, due to the strong corrosive of biomass boiler flue gas, leaks out once being formed
The case where for the notch at place because corrosion can be increasing, situation of leaking out is also just increasingly severe, leaks out more serious, corrodes can be more
Fastly.The case where just needing replacing entire air-purifying chamber in an overhaul life is frequently appeared in, the operation of deduster is seriously affected, makes
At being forced to stop production for boiler.
In view of the above problems, must be improved to dust pelletizing system, overcomes the problems, such as easily to leak out and corrode.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of biomass boiler dedusting that anticorrosion is leaked out
System improves on the basis of existing biomass boiler dust pelletizing system, and the inspection manhole door for being located at dust remover roof is moved
To air-purifying chamber side, and increase the height of air-purifying chamber, it is convenient complete deduster in air-purifying chamber change bag requirement, and maintenance door is adopted
With double-layer structure, have the function of completely cutting off hot-air conduction, prevents biomass boiler bag filter air-purifying chamber from leaking out corrosion.
The utility model is that technical solution used by solving its technical problem is：Provide a kind of life that anticorrosion is leaked out
Substance boiler dust removal system, including bag filter, the air inlet horn mouth and cyclone dust collectors of the bag filter side
Exhaust outlet connection, the bag filter includes the ash bucket of bottom and the cabinet on top, and the cabinet includes the net gas on top
The middle cabinet of room and lower part, the height of the air-purifying chamber are to be placed with multi-section type cloth in the raising middle flask body between 3.2~4.2 meters
Bag, the top of the air-purifying chamber are connected to outlet air flue, and the side wall of air-purifying chamber is equipped with the double-deck inspection manhole door, the double-deck maintenance
Manhole door includes inside door and external door, is air adiabatic layer between the inside door and external door.
The inside door and external door are respectively equipped with self-priming door lock or magnetic-attraction door lock.
The utility model is based on beneficial effect possessed by its technical solution and is：
(1) the biomass boiler dust pelletizing system that a kind of anticorrosion provided by the utility model is leaked out is in existing biomass boiler
It is improved on the basis of dust pelletizing system, the inspection manhole door for being located at dust remover roof is moved into air-purifying chamber side, it is convenient net
That deduster is completed in gas chamber changes bag requirement, and air-purifying chamber rest part is totally-enclosed, and maintenance door uses double-layer structure, inside door and external door
Between be air adiabatic layer, can significantly completely cut off hot-air conduction, to realize multi-layer sealed effect, oxygen content increase is avoided to cause
Maintenance door further corrode；
(2) air-purifying chamber for the biomass boiler dust pelletizing system that a kind of anticorrosion provided by the utility model is leaked out is in traditional cloth
Increase between 3.2~4.2 meters on the basis of bag dust collector, guarantees that personnel can directly enter from the double-deck inspection manhole door of side
Maintenance avoids top from opening up large area cover plate for manhole, to eliminate air leakage phenomena, reduces a possibility that place of leaking out is corroded；
(3) the double-deck inspection manhole door for the biomass boiler dust pelletizing system that a kind of anticorrosion provided by the utility model is leaked out
Inside door and external door self-priming door lock or magnetic-attraction door lock can be used, convenient for folding, avoid service personnel forget cause inside door and
External door is forgotten to close.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the biomass boiler dust pelletizing system that a kind of anticorrosion provided by the utility model is leaked out.
In figure：1- cyclone dust collectors, 2- enter the wind horn mouth, 3- air-purifying chamber, cabinet in 4-, 5- ash bucket, 6- outlet air flue.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The utility model provides a kind of biomass boiler dust pelletizing system that anticorrosion is leaked out, and referring to Fig.1, including cloth bag removes
The air inlet horn mouth 2 of dirt device, the bag filter side is connected to the exhaust outlet of cyclone dust collectors 1, the bag filter
The cabinet of ash bucket 5 and top including bottom, the cabinet include the air-purifying chamber 3 on top and the middle cabinet 4 of lower part, it is described in
Multi-section type cloth bag is placed in cabinet 4, the top of the air-purifying chamber 3 is connected to outlet air flue 6, and the side wall of air-purifying chamber 3 is equipped with double
