Road connects, setting filter regeneration mechanism in described filtering dust system.By including connecting admission line and discharge duct
Airtight disengagement chamber in setting filter regeneration mechanism, can filter body running for a period of time after, filtering bodies filter capacity because
Decline to a great extent when can not meet normal work for the tar coal ash attachment of the gentle in the hole in surface, by filter regeneration machine
Structure works, and filtering bodies is restored to due level up, repeated regeneration directly decreases the input of filtering bodies, also significantly
Improve the service life of filtering bodies.
United States Patent (USP) US 09/271,741 disclose " for the method and apparatus of filter synthetic gas ", which employs one
To rod cleaner, each cleaner have one for receive need to filter the entrance side of non-filter synthetic gas of heat, with
And one be used for discharge filtration forming gas outlet side.Two cleaners can be accommodated with a housing, or be each
Cleaner provides a single housing.Alternately supply combustion air to each rod cleaner, so that heavy burning
Another cleaner is allowed to filter the non-filter synthetic gas of heat while amassing the oxidable particle on a cleaner.One
Or multiple switching valve is connected to described combustion air feedway, for alternately supply combustion between two rod cleaners
Burn air.
However, above-mentioned patent yet suffers from following some defects：
（1）Although technical scheme disclosed in above-mentioned patent solves to a certain extent asking present in high-temperature oil gas dedusting
Topic, but, with the carrying out of filter process, still there are part tar precipitate and dust to combine, formed and even quickly form ash
Cake is attached to filtering bodies surface, so that cleaner is comparatively fast blocked, lead to one or one group filtering bodies normal work when
Between shorten, particularly during the industrialized production of the high Dust Capacity of atm number, be unfavorable for entirely interacting the steady of regenerating unit
Qualitative, and then greatly increase operation expense.
（2）United States Patent (USP) US 09/271,741 disclosed " for the methods and apparatus of filter synthetic gas ", however, should
Cleaner is limited only to the less gas cleaning at high temperature to tolerance, and atm number is such as even more big in thousands of m3/h, m3/h up to ten thousand
For the filtration yield of numerical value, technical scheme disclosed in this patent is obviously also helpless, and one is that filter area is too small, only pin
A kind of possible thinking and idea are provided for laboratory stage.The air intake that two is faint is difficult to ensure regenerating unit
Interior a large amount of filtering bodies carry out uniformity and the uniformity of regenerative response, also cannot obtain the harmony of reaction temperature.
At present, the record of the solid and gas separation problem of high-temperature high dust oil gas is not still solved using electric dust-removing equipment.In addition,
When biomass pyrolytic, from the point of view of situation about retrieving at present, either compression blocks or bulk thing, after its pyrolysis
Gas there is also the situation of the high dirt of oil-containing, and various dedusters and its change all can not fundamentally solve atm number high-temperature high dust height
A dedusting difficult problem in oil gas body.In addition, a problem put in face of the technical staff in art is, in combustible gas
In body dust removal process, by the way of electric precipitation, it is extremely hazardous behavior, because during electric precipitation, often occur
The phenomenon producing electric discharge because of the enrichment of electric charge occurs, and producing spark inside fuel gas is in art
Technical staff must avoid.
Content of the invention
For solving the above problems, the utility model provide a kind of be used in pyrolysis of coal, dust-laden in biomass pyrolysis process, containing Jiao
Oily pyrolysis gas remove electric dust-removing equipment and the system of dust.
A kind of electric dust-removing equipment, including electric dust-removing equipment body, described electric dust-removing equipment body arranges preheating device.
Described preheating device is overall preheating device.
Described preheating device is hot-gas channel, the internal cavity of described hot-gas channel and electric dust-removing equipment body
Connect.
Described electric dust-removing equipment body arranges regenerating unit.
Described regenerating unit is physics regenerating unit and/or chemical regeneration device.
Described physics regenerating unit is to be arranged on to scrape mechanism on easily attached ash part.
Described chemical regeneration device is Poor oxygen gas input mechanism.
A kind of electric dust removing system, described electric dust removing system includes two sets or many set electric dust-removing equipments are in parallel.
The present inventor's research finds, for atm number dust-laden, the dedusting containing tar pyrolysis gas, because coal material, living beings
Stir or be pyrolyzed under air-flow drives, lead to dust content in the admixture of gas producing very high, and contain in mixed gas
Carbons easily separate out material such as tar Jiao, class bituminous material can be existed with gaseous state, not right only in the environment of high temperature
Under conditions of it is preheated, the such as tar containing the easy precipitate of carbons in high-temperature high dust oil gas is burnt, class bituminous material from rapid from
In gaseous mixture separate out phenomenon, be enriched in electric dust-removing equipment inner surface, collecting polar plate and corona discharge electrode rod, precipitate with except in dust and gas
Dust combine rapidly and generate filter cake, and be attached in electric dust-removing equipment inner component surface and space, have a strong impact on gas
Ionization and the absorption to powered dust for the collecting polar plate, and the dust of oil-containing not easily passs through hammering to remove on collecting polar plate
Dust, this is also the reason high-temperature oil gas dust removal field can not carry out dedusting using electric dust-removing equipment for a long time place.And
Before electric dust-removing equipment is started working, electric dust-removing equipment is preheated so that electric dust-removing equipment internal temperature and by except dust and gas
Temperature is close, will preferably avoid because excessive temperature differentials bring containing carbons easy precipitate precipitation phenomenon from gaseous mixture
Occur.
Those skilled in the art it is also believed that, either cleaner maximize or the feelings of lab pilot plant, lab scale
Under condition, after high-temperature oil gas dust removal process starts, the temperature value that the temperature of cleaner will soon be increased to dedusting gas is attached
Closely, a whole set of complicated pre-heating system need not be further added by preheating is exclusively carried out to it, belong to the behavior that at all there is no need, so
Do not see any record that electric dust-removing equipment is preheated in the prior art.
The present inventor finds in very long research process finally, the correlation in whole cleaner internal cavity and cavity
Between part, regional, temperature consistency is very crucial and important.Gaseous mixture containing the easy precipitate of tar gas enters airtight point
After in chamber, gas molecule on the microcosmic moment after air inlet pipe enters cavity leads to greatly pressure to become due to the unexpected change in space
Little, and close to outlet pipe when make pressure become big, the easy precipitate containing carbons is done by pressure change in hot environment
Disturb and be just very easy to separate out, be liquefied as tar Jiao and class bituminous material, if gas molecule is during flowing, and because
Lead to that large area irregular Temperature Distribution occurs in cleaner for local heating, non-uniform heat flux, temperature province is indirectly
The height heat radiation that necessarily occurs of inequality and heat transfer, uneven irregular fever transmission can distort gas molecule, easy containing carbons
Precipitate molecule particles are moved towards with the flowing in the attaching space of dust granules, greatly increase containing carbons easy precipitate molecule particles
Collide the probability of simultaneously conglomerate polymers with dust granules, oily asphalitine aggregate becomes big and becomes heavy, also cannot maintain
Vaporized state, simultaneously irregular air motion also increase tar Jiao molecule and dust molecule, the contact frequency of internal part, increase
Add the probability that asphalitine polymerization separates out, very easy appearance such as tar containing the easy precipitate of carbons is burnt, class bituminous material is from mixing
In gas, quick precipitation is attached to the phenomenon affecting normal dedusting on dust.
During industrialized production, cleaner is very huge, hundreds of easily, thousands of cubes of volume, the inside
Parts are more, and the inlet chamber to whole system and outlet chamber are that dedusting environment carries out high temperature preheating, can produce larger economy
Cost；Even more important property is, using high-temperature gas or other modes, whole dedusting cavity is carried out heating generally to introduce big
Amount high-temperature gas, and the high-temperature combustion gas being introduced into easily are mixed into and treat in dedusting high temperature oil-containing gases, change pyrolysis gas
Composition, reduces its economy, and the gas separating treatment in later stage is just more complicated.General high temperature oil-containing gases are all inflammable and explosive simultaneously
, with heat forms such as high-temperature gas, electric heating, whole cavity being preheating to the condition of high temperature is a kind of dangerous behavior, so to height
Warm oil-containing gases cleaner is preheated, and on the one hand can reduce the economy treating dedusting gas, on the other hand as increasing
Plus the operation such as electrothermal mechanism, switching high-temperature gas, reduce the safety and reliability of its warm, dust removal process.
Therefore, the generally teaching of this area is：It is not necessary to right in high temperature dust, the dust removal process of pyrolysis gas containing tar
Cleaner is preheated because pyrolysis gas start dedusting will firing equipment rapidly；Even if preheating, also without preheating electrode plate
With the space outside corona wire and part, less will recognize that and preheated using overall, because the result that it is integrally preheated not only can
Increase heating cost and equipment cost, and also likely bring reduction and the whole system security of pyrolysis gas economic benefit
Reduction.
A kind of electric dust-removing equipment of the present invention, described electric dust-removing equipment body arranges preheating device, and electric dust-removing equipment body is even
Tap into tracheae, outlet chamber connects escape pipe, using the preheating device being connected with electric dust-removing equipment chamber body, the electricity of cold conditions is removed
Dirt apparatus body inner chamber carries out being preheating near the Temperature numerical that high-temperature high dust contains during tar gas entrance cleaner, after preheating
Electric dust-removing equipment chamber body be passed through high-temperature high dust contain tar gas, high-temperature high dust contain tar gas in the charged rear quilt of dust
Battery lead plate adsorbs, and filter mechanism regenerating unit is capable of the removing to floating dust on battery lead plate and ash cake, to ensure whole dedusting
Equipment normal work.
In the prior art, in the electric dust-removing equipment of a large amount of high temperature oil-containing gases and method document, not to cleaner
The related record heated.More not overall to the electric dust-removing equipment uniformly record of preheating and needs.So-called uniform, it is preheating
All regions of whole cleaner inner chamber and the temperature of all parts are relatively uniform afterwards, and the result of preheating is cleaner inner chamber
The each part temperatures in each position are consistent or basically identical.The scope of overall preheating, is may to lead to filtration gas in cleaner
Cross or possible contact area or position.
The utility model by after electric dust-removing equipment body is integrally preheated so that each region, each part in cleaner
Temperature relatively uniform consistent, the high oily high dirt gas molecule of high temperature that enters in the consistent overall situation of temperature can face less
Temperature change and states of matter change, even if in the presence of dust, are also less susceptible to the change of local space states of matter and cohesion analysis
Go out.It is whole to cleaner that the entirety preheating such as high-temperature gas of Wind Volume of preheating mechanism is passed directly into electric dust-removing equipment chamber body
Body heats, and is capable of three below feature：The precise control of contact, no dead angle, heating-up temperature and heating process, and in advance
Thermal velocity is fast, energy-conservation, remarkable in economical benefits；Other mode of heatings such as outside sandwich of overall heating leads to hot blast, cavity surrounding entirety
The ways of realization such as parcel heat generating components can also realize no dead angle, comprehensive preheating, and pre- thermal result is each region in cleaner
Temperature is basically identical, but a large amount of high-temperature gases more preferably remaining circulating air participation integrally heat the preheating of cleaner
Form.In addition, it is critical that because by the way of using overall preheating, in filter process, cleaner cavity inner wall,
The temperature of many interior fittings such as cathod system, anode system, vibrated system is relatively uniform, and the heat transfer in cavity is less,
Substantially increase the controllability of system, reliability of operation and uniformity.Avoid appearance during dedusting locally and whole
Body, central authorities and fringe region dedusting work out of step conditions.
The molecular state of oil gas is unstable in itself, in hot environment, often because heat absorption and lead to two or
Two or more organic molecule is interacted and is combined to form a macromolecular in the form of covalent bond, and with shaking off of small molecule
Constantly there is condensation reaction, molecule is solid-state from gaseous, liquid coking, be combined generation ash cake obstruction with dust and filter.And the present invention
Technical scheme cavity is carried out with overall preheating, it is relatively uniform all even stable to filter environment temperature, asphalitine occur pyrolysis and
Polycondensation reaction probability substantially reduces, and also occurs without low-temperature liquefaction phenomenon, and tar is burnt, the minimizing of class bituminous material amount of precipitation directly presses down
The speed that filter cake processed generates.
Two electric dust-removing equipment parallel connections, are capable of dedusting gas and switch on two cleaners, you can to make simultaneously
With realizing the double of dedusting tolerance, wherein maintenance do not stopped work can be regenerated, complete electric dust-removing equipment overall again
Giving birth to online, when regeneration especially with chemical regeneration device, two sets of electric dust-removing equipments in parallel are more convenient,
It is capable of two sets of electric dust-removing equipments in parallel and does not stop production alternately regenerating.
