Description
Technical field
The present invention relates to electric precipitation field, specifically a kind of low low temp. electric deduster.
Background technology
Low low temp. electric dedusting technology is electric precipitation new technology, not only can improve dust collection efficiency, meet low emission requirement, and can save electric consumption of coal and reduce power consumption, reduces upstream device specification, removes most SO
3, reduce desulfurization utility rate of water etc., meet national environmental protection policy requirements.And how the reentrainment of dust that the domestic heating measures for low low temp. electric dust collector ash hopper, the rapping of low low temp. electric deduster cause effectively prevents, the anti-condensation of insulator and cracking measure, manhole door etc. easily leak out technical method that the critical problems such as an anticorrosion of dependent office position are not correlated with.
Summary of the invention
The object of the present invention is to provide a kind of low low temp. electric deduster, effectively can solve existing low low temp. electric deduster ash poor fluidity, the easily problem of blocking ash bucket.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of low low temp. electric deduster, comprises exhaust gases passes, be provided with at least one group of stationary electric field in exhaust gases passes, often organize below stationary electric field and be equipped with an ash bucket, described ash bucket is provided with heater.
Preferably, described heater cover ash bucket from bottom more than 2/3rds height; Ensure that the flue gas entering ash bucket has enough temperature, the mobility of heater excessive height then flue gas is affected.
Preferably, described heater is heating tube dish, and the outside of described heater is also coated with heat-insulation layer; Heating tube dish can be suitable for multiple heat medium, increases heat-insulation layer and can reduce energy consumption.
Preferably, the heat medium in described heater is steam, and up, gas outlet is in below for the air inlet of described heater; Steam easily obtains to be convenient to reduce operating cost, and because ash bucket is infundibulate, air inlet can make the upper and lower temperature of ash bucket be consistent up.
Preferably, described heater becomes the coiling of S shape to be fixed on ash bucket sidewall; Increase heating surface (area) (HS as far as possible.
Preferably, described stationary electric field top is provided with insulator room, and described insulator room is supporting is provided with heat blower; Purge and exclusion insulator in flue gas, thus ensure insulator not dust stratification do not condense.
Preferably, along flow of flue gas direction, in the exhaust gases passes at stationary electric field rear, be provided with rotation electrode electric field; Because flue-gas temperature reduces, flue dust ratio resistance declines, and flue dust adhesion decreases, and adopts rotating electrode type electric field effectively can prevent reentrainment of dust.
Compared with prior art, advantage of the present invention is: on ash bucket, arrange heater, can effectively keep the temperature in ash bucket to be greater than 90 DEG C, thus ensures the mobility of dust in ash bucket, not easily causes stifled ash, significantly promotes the stability of electric cleaner.

Detailed description of the invention
Consult the embodiment that Fig. 1 is a kind of low low temp. electric deduster of the present invention, a kind of low low temp. electric deduster, comprise exhaust gases passes 1, at least one group of stationary electric field 2 is provided with in exhaust gases passes 1, often organize below stationary electric field 2 and be equipped with an ash bucket 3, ash bucket 3 is provided with heater 4, and heater 4 outer cladding is by heat-insulation layer, and heater 4 covers the height of from bottom ash bucket 3 more than 2/3rds.
As shown in Figure 2, heater 4 is heat(ing) coil, and heat medium is steam, and up, gas outlet 6, in below, becomes S shape to be fixed on ash bucket 3 sidewall to air inlet 5; On three outer walls of ash bucket 3 bottom mounting disc around seamless pipe as heat(ing) coil, heat(ing) coil upper end is connected with air inlet pipe, lower end is connected with escape pipe, the steam of pressure and temperature is necessarily had to reach the object of heating by conveying continuous in heat(ing) coil, make, assembling time necessarily require pipe withstand voltage, do not leak out, putting before this, operation that can be steady in a long-term, reduces maintenance workload.
As shown in Figure 3, stationary electric field 2 top is provided with the insulator room 7 of placing negative electrode insulator, although there is electrical heating negative electrode insulator outside, insulated porcelain sleeve heat conductivility is poor, thickness is large, therefore inner temperature is still identical with flue-gas temperature, the existence even owing to leaking out, and flue gas local temperature can lower than acid dew-point temperature even salt acid dew-point temperature, the sulfuric acid even condensation of hydrochloric acid may be there is, thus cause insulator insulation to decline, affect dust removal performance, even occur discharge short or insulator Cracking Failure; Heat blower 8 is set by supporting in insulator room 7, hot blast is blown into insulator inside, purge and squeeze the flue gas in insulator, thus ensure insulator not dust stratification do not condense.
Flue-gas temperature reduces, flue dust ratio resistance declines, flue dust adhesion decreases, reentrainment of dust can increase, for preventing reentrainment of dust along flow of flue gas direction, in the exhaust gases passes 1 at stationary electric field 2 rear, be provided with rotation electrode electric field 9, rotation electrode electric field 9 can clean by holding anode plate, avoid inverse corona, effectively solve high resistivity dust and to gather dust difficult problem; Reduce reentrainment of dust to greatest extent, significantly reduce electric cleaner outlet dust concentration.
The foregoing is only specific embodiments of the invention, but technical characteristic of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
