Description
Technical field
The utility model is related to a kind of high-efficiency dust removal system.
Background technology
In recent years, dust pollution has had a strong impact on national life, and as whole society's focus of attention, country also puts into effect various
Policy carries out keypoint treatment.
Transported outward to store flying dust by automobile in thermal power plant flying dust storehouse.There are two kinds of entrucking modes：Dry ash entrucking and tune
Wet grey entrucking.During flying dust entrucking, often produce in substantial amounts of airborne dust, the airborne dust that damping ash is produced and be also mingled with substantial amounts of water
Vapour, the severely afflicated area for causing grey storehouse entrucking region to be dust pollution is always each power plant difficult point region urgently to be resolved hurrily.
Conventional processing scheme：
(1) hand sweeping
Flying dust free settling, ground dust stratification uses hand sweeping entrucking.
Shortcoming：Diffusion to dust lacks effective improvement, during hand sweeping, triggers dust to fly upward again, causes
Secondary pollution.
(2) hydrodynamic cleaning
Flying dust free settling, ground dust stratification is collected to cesspool, the simple static processing heel row of sewage by pressure flush of water
Put, bottom deposit sludge periodic cleaning, cesspool is arranged on grey base area.
Shortcoming：Diffusion to dust lacks effective improvement, the flying dust of superficial deposit becomes mortar after being flush with water, lack
It is effective to administer, form secondary pollution.
(3) vacuum dust collecting truck is cleaned
Flying dust free settling, ground dust stratification is cleaned by vacuum dust collecting truck.
Shortcoming：Diffusion to dust lacks effective administer.
(4) bag-type dust removal system
Negative pressure pipe network system is set around grey storehouse discharge port, a range of dust is aspirated.The powder being sucked
Dirt and admixture of gas are purified using sack cleaner, and the air after purification drains into air, and the dust that purification is collected periodically passes through
Grey slag car outward transport.
Shortcoming：The grey airborne dust diffusion of damping is lacked and effectively administered.
Contain substantial amounts of steam, especially winter northern area in the airborne dust produced due to damping ash, hydrometeor is very
Seriously, the airborne dust containing steam has very strong cementability, can be bonded on cloth bag rapidly, paste bag phenomenon occurs, causes cloth bag
Deduster loses clean-up effect in the shorter time, so as to cause thrashing.Dust cementability containing steam is very strong, uses
Conventional pulse, which cleans or connects material using waterproof anti-sticking, all can not effectively solve the problem.
It is above-mentioned it is several be the common processing mode of power plant, can not all efficiently solve dusting problem, preceding 3 kinds of schemes are also
The appearance of secondary pollution can be caused, although the 4th kind of scheme can effectively handle dry ash airborne dust, raising for damping ash can not be solved
Dirt problem.
