Description
Technical field
The present invention relates to a kind of coagulation bag hose, a kind of coagulation the bag hose particularly for field of Environment Protection industrial furnace flue-gas granule, removed.
Background technology
In industrial furnace, contain dust and minuteness particle, conventionally adopt electric cleaner and bag hose (also claiming sack cleaner) that dust and minuteness particle are separated from gas, flue gas is purified, to meet requirement or the requirement of downstream process to dust contained flue gas concentration of environmental emission standard.In flue gas, minuteness particle quantity is many, particle diameter is little or discharge standard requires when strict, and the purification efficiency of conventional electric cleaner and sack cleaner does not reach requirement.Under this background, can adopt additional electrical coalescence technology to improve arresting efficiency, first electricity consumption coalescer makes minuteness particle coalescence in flue gas become large-size particles, then removes bulky grain with electric precipitation or bag-type dusting, realizes and puies forward effect.
Have data introduction, Australian Indigo company has developed a kind of flue coalescer, is arranged on the flue of electric cleaner front end, and with the supporting use of connecting of electric cleaner, flue gas first makes minuteness particle coalescence by flue coalescer, then enters electric cleaner and purify.The shortcoming of this mode is to take up an area greatly, invests highly, when place is limited, cannot implement.
The prerequisite of above background technology is usingd electric cleaner as smoke catching mode, does not relate to bag-type dusting.Electric cleaner and sack cleaner all belong to high-efficiency dust remover, but electric cleaner is not high to the trapping effect of minuteness particle, and sack cleaner to the arresting efficiency of dust higher than electric cleaner, particularly aspect minuteness particle trapping, showing clear superiority.At present, also not by coagulation technology and compound relevant report and the data of bag type dust removing technology.
Summary of the invention
The electric cleaner that exists for above-mentioned prior art is not high to minuteness particle arresting efficiency, flue coalescer takes up an area large and high cost is not enough, the invention provides a kind of coagulation bag hose, realize coagulation technology and bag type dust removing technology compound, can effectively solve the problem that prior art exists.
Solution of the present invention is: propose a kind of coagulation bag hose, electric coalescer, bag hose and automatic control system, consist of, automatic control system is connected by holding wire and electric coalescer and bag hose; Bag hose comprises import loudspeaker, airflow-distribution board, middle casing, upper box, ash bucket, filter bag, pulse spraying equipment; Casing is installed on middle casing top, filter bag is suspended on the card of upper box, pulse jetting deashing device is set in upper box, ash bucket is installed in the below of middle casing, import loudspeaker are arranged on middle casing airintake direction side, airflow-distribution board is arranged on the porch of import loudspeaker, and electric coalescer is arranged in the import loudspeaker of bag hose.
Coagulation of the present invention bag hose, electricity coalescer comprises discharge electrode, discharge electrode framework, insulating suspension bearing, high voltage source, earthing pole, suspention beam, discharge electrode is arranged on discharge electrode framework, discharge electrode framework hangs by insulating suspension bearing, high voltage source is to discharge electrode power transmission, earthing pole is arranged on suspention beam and forms ground connection, and suspention beam is welded on bag hose import loudspeaker housing.
Coagulation of the present invention bag hose, acoustic wave soot blower is arranged on bag hose import loudspeaker top or sidepiece, produces high energy sound wave to discharge electrode and earthing pole deashing during work; Air bubble is arranged on top or the sidepiece of bag hose import loudspeaker, utilizes Compressed Gas winding-up, to discharge electrode and the auxiliary deashing of earthing pole.
Coagulation of the present invention bag hose, discharge electrode and earthing pole, alternate layout in bag hose import loudspeaker, forms some passages.
Coagulation of the present invention bag hose, high voltage source comprises the high voltage source of an output malleation, and the high voltage source of an output negative pressure, can be respectively to the discharge electrode of alternate passage, applies positive high voltage and negative high voltage, discharges positive charge and negative electrical charge.
Coagulation of the present invention bag hose, discharge electrode can be the different discharge electrode forms such as prickle wire, astroid, circle line, its quantity is adjustable.
Coagulation of the present invention bag hose, earthing pole can be the pole plate of Z-shaped pole plate, C shape pole plate, meshed polar plate or other form, earthing pole quantity is adjustable.
The operation principle of coagulation of the present invention bag hose is: high voltage source applies positive or negative high voltage to discharge electrode, sets up the electric field of alternate positive and negative between discharge electrode and earthing pole, and discharges respectively positive and negative electric charge.When flue gas enters after import loudspeaker, first by airflow-distribution board, carry out uniformity adjustment, then enter electric field, in flue gas, particle dust is distinguished positive charge and negative electrical charge on lotus in different passages, and flue gas flows out after power plant, due to positive and negative charge interattraction, the dust granules of positively charged is combined with electronegative dust granules, and coalescence becomes bulky grain, then filters through filter bag, thereby realize dust granules, from flue gas, remove, the flue gas after purification is discharged from the afterbody of upper box.
In electric coalescer, on discharge electrode and earthing pole, adhere to after a certain amount of dust, automatic control system is sent instruction, and acoustic wave soot blower and air bubble are started working, and discharge electrode and earthing pole are carried out to deashing, and the dust coming off falls into ash bucket.After a certain amount of dust of filter bag surface attachment, filtration resistance uprises, and automatic control system is sent instruction, and pulse jetting deashing device is started working, and to filter bag ash removal, the dust coming off falls into ash bucket.
Beneficial effect of the present invention is: take full advantage of the feature that bag hose arresting efficiency is high, added again minuteness particle coagulation function also thereon, strengthened the trapping effect to minuteness particle in flue gas (as PM2.5, PM10), electric coalescer and bag hose are organically combined into an integral body, take full advantage of the space of bag hose import loudspeaker, do not need electric coalescer is set separately, thereby reduced equipment investment and floor space, be convenient to engineering construction and technological transformation.
