Description
Technical field
The utility model relates to a kind of dust arrester, and a kind of power plant and Industrial Boiler Horizontal electric cloth complex dust collector particularly is provided.
Background technology
High-voltage electrostatic dust separator for a long time, obtains the most general, the most widely promotion and application in the air contaminant treatment industry as the industrial flue gas cleaning equipment that a kind of technology maturation, making are relatively simple, maintenance cost is low.Yet (new standard is 50g/Nm along with the raising of Environmental Protection in China discharge standard
3), a lot of active service electric precipitations do not reach new standard, have to carry out the secondary transformation, grassroot project also faces new environmental protection pressure simultaneously, present widen, the traditional means such as lengthening, increasing, be the improvement that belongs to body construction, actual effect is limited also, the equipment investment cost performance is low, also is not inconsistent and builds the national industrial policies of economizing type, environment-friendly type society.
High-voltage electrostatic dust separator can be removed the large flue dust of high concentration and particle diameter, but that this deduster takes up an area the space is large, reaches high efficiency of dust collection cost of investment very high, and some special coal types dust removing effects is extremely undesirable.The defectives such as and sack cleaner adapts to various coals and dust removing effects is good, and production cost is low, and has certain desulfidation, single sack cleaner to have again the filter cloth life in application short, and electromagnetic impulse valve demand and maintenance workload are large.When coal-burning power plant and Industrial Boiler startup, need throw oil firing, adopt electric cleaner then can't put into operation, cause the pollution of oil smoke to environment.
The utility model content
The utility model purpose is the deficiency that exists for above-mentioned deduster, provides a kind of efficiency of dust collection high, and the flue dust exit concentration is lower than national environmental protection department and newly issues standard, the more rational Horizontal electric cloth of structure complex dust collector.
The technical scheme that proposes for achieving the above object is: a kind of Horizontal electric cloth complex dust collector, comprise and be located at electric cleaner and the sack cleaner that is positioned at electric cleaner one side in the housing, vertically be provided with many row's minus plates in the electric precipitation interval, positive plate, every row is cloudy, positive plate is staggered to be laid, export the sack cleaner that a side is connected with the horizontal placement of downstream direction at electric cleaner, girder is put cloth bag and is fixed and form several girder unit multilayer is sleeping, girder and bottom girder are connected and fixed, it is characterized in that: the smoke box place in the sack cleaner outlet is provided with air chamber, the gas tank that is connected and moves up and down with the gas tank mobile device is housed in the air chamber, and gas tank is equipped with nozzle corresponding to each layer cloth bag place and at the gas tank sidepiece; Gas tank is connected with piston and blowback pipeline, so that move with gas tank as the piston of reverse-blow pipe compensation; The tensioner of guiding mechanism is flexible coupling along gas tank outer wall and its formation.
The outlet opposite of each layer cloth bag arranges the grid that is made of square tube in the sack cleaner, and cloth bag passes the grid place flange is housed, and is pressed in the outside of grid by flange and sealing ring.
The porch of each layer cloth bag is provided with a bag cage locating rack in the sack cleaner, and locating rack is fixed on the girder.
Installation high-voltage electrostatic precipitator before the sack cleaner is carried out first first order dedusting, with approximately 90% exhaust gas dust and the clarifying smoke more than the particle diameter 10um fall.The dust concentration that enters like this sack cleaner all is below 3g/Nm3, and particle diameter all below 10um, has namely prolonged the filter cloth bag service life of complex type dust remover, has greatly improved again efficiency of dust collection, and has certain desulfurized effect.Make the profile of whole complex type dust remover be equal to electric cleaner fully the filter bag lateral arrangement, filter bag length can be determined according to total filter area that needs.So not only guarantee the grey passage that falls between bag and the bag, also save large quantity space.The filter bag outlet sealing device adopts the sealing of modular unit grid type.Design the reliable deashing device of new type of safe, thereby reduced the repair and maintenance workload of traditional sack cleaner, utilized the space of former one or two electric field of electric cleaner and the efficient that weight just can reach five to six electric fields of electric precipitation.
The utility model compared with prior art has following characteristics:
1, dust removing effects is remarkable, and efficiency of dust collection is more than 99.9%, and the flue dust exit concentration is lower than 50mg/Nm
3, satisfy the requirement of future " thermal power plant's air pollution emission standard " that national environmental protection department newly issues fully, strengthened the adaptability of device processes flue gas; Also have simultaneously preferably desulfurized effect, do not add any desulfurizer desulfurization degree all more than 6.5%;
2, this complex dust collector has overcome that the electrostatic precipitator floor space is large, the one-time investment cost is high and be equipped with the problems such as a large amount of high pressure and rectifying installation; The efficiency of dust collection that has effectively solved electric cleaner is subjected to the dust physical characteristic to affect a large difficult problem, and independent electric cleaner is difficult for the ratio resistance of capture less than 10
4Ω .cm and be higher than 5 * 10
11The dust of Ω .cm carries out purified treatment at an easy rate;
3, project organization is scientific and reasonable, and stable equipment operation is simple in structure and be easy to install, and only needs the cathode and anode of its last electric field is taken out, and installs filter dust collector to get final product, and small investment, instant effect, saves time; Required accessory and material all can adopt home products, Decrease production cost, and be convenient to maintenance;
4, this deduster is compared with long bag off-line pulse bag type dust collector, and the former only needs to install a cover pulsation deashing device, and the latter need install 352 of pulse valves (smoke treatment amount 133.2 ten thousand m
3/ h), and mostly adopt import parts, expensive, both cost ratios are 1: 140;
5, this ash-cleaner for dust remover has adopted piston and gas tank mobile device, compares with pulse bag type dust collector, and structure is simplified greatly, and adaptability increases, long service life, and maintenance workload is little;
6, the filter bag dust removing units can be put into operation through testing this complex type dust remover, carry out dedusting and purifying oil fume, electric cleaner can't put into operation, cause the defective of oil smoke environmental pollution when having overcome coal-burning power plant and Industrial Boiler startup throwing oil firing.
