Description
Technical field
The present invention relates to solid gas separation technology fields, are a kind of rotary grate automatic dust removing apparatus more specifically.
Background technique
Currently, thermal power plant electric precipitation positive pneumatic conveying system, the commonly used cloth bag of terminal storehouse exhaust gas treatment device
Deduster, working mechanism are: the particulate matter in dust-contained airflow is obstructed in positive pressure gas flow flotation process by dust-removal cloth-bag
It is adsorbed on cloth bag filtering surface, gas then passes through cloth bag and is discharged into atmosphere, because of the accumulation of cloth bag filtering surface particulate matter, cloth bag gas permeability can be made to become
Difference reduces efficiency of dust collection, is swept by air pulse blowback, so that the dust particles being adsorbed on cloth bag filtering surface is fallen off, efficiency of dust collection obtains
To restore, solid gas separation is carried out repeatedly, realizes dusty gas dust separation discharge.The bag filter of the prior art is former
It manages structure (attached drawing 6), is that the combination of cloth bag cylinder is fixed in panel to dispose in a cabinet, is separated into housing interior volume
Cloth bag filtering surface side and cloth sack side, cloth sack side are communicated with the atmosphere as cabinet gas outlet, and filtering surface side is contacted with dusty gas is
Cabinet ash-laden gas entrance, blowback compressed air introduce cloth sack by solenoid valve.Bag filter be typically mounted at the top of powder cabin (with
For the electric dust-removing equipment system of thermal power plant), entrance is connected to powder cabin warehouse, and outlet and atmosphere communicate, the reference of blowback gas source
Compressed air is introduced compressed air into bag chamber by controller drive magnetic valve, and successively each cloth bag arteries and veins is completed in sequential control
It rushes blowback to sweep, returns again to powder cabin after removing the dust particles on cloth bag filtering surface.
Bag filter advantage structure is simply contributed greatly, therefore high dust collection efficiency is widely used in thermal power plant electricity and removes
Dirt pneumatic conveying end storehouse dedusting exhaust.
Practical application discovery, there are many problem and shortage for bag filter: 1. by bag filter working principle it is found that
As dusty gas is by continuous dust removal process, cloth bag surface absorption particulate matter gradually increases, and ventilation capacity is gradually deteriorated, if cannot
It timely and effectively removes, efficiency of dust collection can reduce；2. bag filter normal work needs compressed air blowback cloth bag, if when long
Between cannot get blowback air-flow, not only efficiency of dust collection reduction gradually lose dustproof function, pressure rise causes wharf explosion in storehouse when serious
Accident, there are security risks；3. if blowback air-flow not instead of air pulse, purges, high pressure draught is quickly by dedusting for a long time
Cloth bag is blown brokenly, and dusty gas is directly discharged into atmosphere pollution environment；4. bag filter normal work needs compressed air purging, energy
Source consumption is big, and Social benefit and economic benefit does not ensure.
Summary of the invention
In view of the deficiencies of the prior art, the invention provides the following technical scheme: a kind of rotary grate automatic dust removing apparatus, packet
Include: stator shell, rotor grid, dust collecting box, the stator shell cooperate complete, formation revolving door working principle with rotor grid
Structure completes the dusty gas dedusting course of work.
To keep above-mentioned technical proposal more detailed and specific, the present invention also provides optimization technique sides further below
Case, to obtain satisfied practical function:
Techniques described above scheme, the stator shell and rotor grid composition deduster are partially disposed on dust collecting box,
The stator shell includes dusty gas entrance, clean gas outlet and the discharge port being arranged on, and three is in up-side down triangle point
Cloth, wherein discharge port is arranged in underface；The rotor grid be in mouse cage shape balanced structure, including shaft, grille frame,
Filter plate, the long-drawn-out hammer of rapping, the rotor grid is mounted in stator shell by shaft, by stator enclosure interior physical space point
At three working regions, it may be assumed that dedusting area, discharge region, discharge zone respectively correspond the stator shell dusty gas entrance, net
Change gas vent and dust mouth, it is unbalance using rotor grid radius horizontal force, drive rotor grid to be justified in stator shell
Zhou Yundong is completed at the same time dust-contained airflow dedusting, purification gas discharge and dust particles and collects.
The rotary grate automatic dust removing apparatus course of work of the present invention is as follows: the dust-laden that dust-contained airflow is equipped with by stator shell
Gas access enters dedusting area, and the initial stage, ash-laden gas flow point two-way enters rotor grid filtration, all the way through top
The filtering of grid filtering surface, another way are filtered through lower grid filtering surface, after large dust particle encounters upper grid filtering surface, due to gravity
Lower grid filtering surface deposition is fallen to, little particle dust is then attracted to filtering surface, and gradually forms particle group blocking filtering surface, with
Particle group increases, and gravity makes its removing top filtering surface fall to lower part filtering surface, and top filtering surface is ventilative to be restored to continue
Dedusting exhaust, carries out repeatedly；Upper grid filtering surface absorption dust constantly falls to lower grid filtering surface deposition, so that lower part
Grid filtering surface shifts to an earlier date top filtering surface and loses dust removal by filtration function, switchs to store platform, and upper grid continues to keep filtering function,
When dedusting area lower grid stores dust weight, reach that rotor grid radius horizontal gravity is unbalance, and the initial stage terminates.Second-order
Section, as dedusting area lower grid filtering surface dust increases, rotor grizzly level balanced radial force is broken, and torque is generated in shaft
The rotation of rotor grid is driven, after rotor grid rotates, former dedusting area is moved to discharge zone, former discharge zone is moved to discharge
Area, former discharge region are moved to dedusting area, and rotor grid functional area converts discharging and blowback discharge grate filtering surface, dedusting
Function is carried out continuously, and is completed rotor grid until discharging and is entered new balanced steady state, the epicycle course of work terminates under entering
One wheel, is automatically performed gas solid separation again and again, realizes dust-contained airflow dedusting and purification gas discharge.
