Background technology
Under the overall situation of national energy-saving emission reduction, " efficiently, low consumption, reliable, no pollution " has become the hair of dynamical system
Exhibition trend.As clean energy resource occupies the status become more and more important in global economy, gradually form and substituted often with cleaning new energy
" upsurge " of the energy is advised, but the main flow situation of the conventional energy resource such as fuel oil, fire coal will not change in a short time.
No matter gas power system by representative of clean energy resource or often fuel oil, coal fired power systems, the conversion of energy
The burning of the energy is required to, air turns into essential working medium, and its cleanliness factor directly influences the normal operation of power-equipment
And service life.The gas power equipment of early stage, due to lacking the dust in the concern to equipment importation air and attention, air
Particulate matter is collided with equipment, adhered at high speed, cause equipment run after a period of time occur heavy corrosion, abrasion,
The phenomenons such as fouling, cause equipment downtime.
Current most of all kinds of power-equipments run at high speed, such as engine, gas turbine, air compressor machine are substantially at
Longtime running state, maintenance period is long, and cost is high.Therefore, the cleanliness factor of equipment importation air also gradually obtains equipment manufacturer's
Pay attention to, air filtering system turns into the indispensable annex of power-equipment therewith, it is light to play act foot to the normal operation of protection power-equipment
The effect of weight.
The regeneration techniques of filter core, which turns into, extends its service life, and the effective measures of workload and maintenance cost are changed in reduction,
Distinct methods are taken to peel off solid dirt particulate matter from cartridge surface, such as mechanical oscillation deashing, air-flow deashing, pulse backblowing
Deng wherein pulse backblowing ash-clearing technology is widely used because of the advantages of its peeling effect is good, automaticity is high, for super large
The air filtering system of flow, the technology can significantly improve equipment operating efficiency, substantially reduce maintenance cost.
Limitation based on transportation clearance and installation, the air filtering system of super-flow is too big because of air quantity, and single module is difficult
Typically it is multimode modular construction to meet requirement.In the air filtering system of traditional multimode composition, filter core upstream
All module chambers mutually connect, this kind of structure type is applied to the offline pulse backblowing of equipment downtime, filter core.For length
The equipment that phase continuously runs, filter core is in online air intake state, the air filtering system line pulse reverse gas cleaning of traditional form
Afterwards, in dust particles from during cartridge surface comes off, as the air-flow of entrance is adsorbed in cartridge surface again, ash is formed
The second adsorption of dirt, causes pulse backblowing technology ash-removal effect poor.
The content of the invention
Its purpose of the invention, which is that, provides a kind of combined module type air filtering system of the anti-second adsorption of online ash removal,
The system is installed in every group of air filtering core circumferential exterior surface actively inhales apparatus for ash, and surface during air filtering core pulse backblowing is blown off
Dust is suctioned out and collected in time, can effectively solve the problem that the problem of occurring dust second adsorption after filtration system pulse dust cleaning, is improved
Pulse dust cleaning effect and filter core service life.
The technical scheme realized above-mentioned purpose and taken, a kind of combined module type air mistake of the anti-second adsorption of online ash removal
Air filtering core is provided with filter system, including multigroup filter element module, filter element module, described filter element module is by master
The flow and differential pressure requirements of machine equipment are configured, and filter element module is that block form, building block system or superposing type are assembled, described
Air filtering core in every group of filter element module inhales grey branch pipe through dust sucking device connection, and one end of the grey branch pipe of the suction, which is provided with, unloads ash
Ash supervisor is inhaled in valve, unloading valve output end connection, and grey unit, the dust sucking device are inhaled in described one end for inhaling ash supervisor through cinder catcher connection
Number and location must match quantity and the position of the air filtering core of corresponding pulses blowback, realize the accurate suction of pulse backblowing filter core
Ash.
Beneficial effect
The present invention has advantages below compared with prior art.
1st, combined module type air filtering system on-line operation, single or multiple filter element modules carry out online ash removal,
Both effectively dust second adsorption was solved the problems, such as, and do not influence equipment normally to run；
2nd, dust concentrates collection processing, is prevented effectively from and is directly discharged into air, causes environmental pollution；
3rd, filter core pulse backblowing effect is significantly improved, the dust stratification amount of cartridge surface is greatly decreased, filter core resistance is reduced, improving it makes
Use the life-span；
4th, dust sucking device has concurrently simultaneously prevents the online second adsorption of dust and air filtering core from installing support function, effectively improves existing filter
Core fixes the purposes of support bar.
