Abstract
The utility model relates to an electric asphalt fume dust remover used for the asphalt fume produced at the purification of the calcination carbon anodes in a charcoal ink factory or an aluminium factory. The utility model is manufactured to solves the problems of the existing dust remover of low purification efficiency, unstable work, and inacceptable exhaust requirement. The utility model is mainly composed of a tube body, a full ionization anode, a cathode system, a spray cleaning extinguishing device, etc. The temperature of an asphalt softening point precipitated on the full ionization anode is controlled by steam. The utility model has the advantages of high purification and dust removal effect, convenient installation, convenient adjustment, high safety in long running, stability is long running, etc. The utility model can be used for the purification of the asphalt fume in the charcoal ink factory or the aluminium factory, and can be used for the purification of the exhaust gas and the coal gas in the coking production in an iron and steel factory.
Description
The utility model belongs to carbon element factory or aluminium manufacturer and be used to purify the glance coal electric cleaner that the bitumen flue gas that produces is used when the roast carbon annode, also is applicable to the purification of steel plant's coking production tail gas and coal gas.
At present, the asphalt smoke gas purifying that carbon element factory or aluminium manufacturer are produced when manufacturing carbon annode mainly is to use the concentric-ring pattern electric cleaner, and the precipitation anode of this deduster is to be fitted together by a plurality of different-diameter anodic deposition pipe boxes.The center line of each pipe coincides, and is called concentric-ring pattern.Cathode line is evenly distributed in the space of each anode pipe.Because the space between each anode pipe is a ring-type, so the distance between cathode line and the anode is inhomogeneous.Because of this distance is difficult to guarantee consistent.So the ionization effect of deduster is relatively poor, purification efficiency is low, fluctuation of service; The Installation and Debugging of equipment are also relatively more difficult.Sediment on the anode tube is many in addition also easy to clean not.When the flue-gas temperature rising, flue and electric field easily catch fire, and burn out cathode line or precipitation anode, and deduster can't be worked.Though external dry cleaning efficient is higher, the expense of investment and operation is also higher, and floor space is also bigger.
Through international online retrieval, do not find and the akin relevant document of the utility model.
The utility model is that udst separation efficient height, Installation and Debugging are convenient, the sediment on the antianode is cleared up and spray Cleaning for High Capacity and the glance coal electric cleaner of self-extinguishing, explosion-protection equipment is arranged at any time for having of designing at the deficiencies in the prior art.
The utility model is realized by following measure.The main body of electric cleaner is made up of cylindrical shell, precipitation anode system, cathod system, heating cleaning system, spray cleaning system and feed system etc.The precipitation anode tube of some same sizes is housed in the cylindrical shell of deduster, forms the anode tube bank.Anode is restrained arranged vertical in sequence, and is fixed by last lower perforated plate; Center in each precipitation anode tube hangs a cathodic electricity hachure, and corona wire is fixed by suspension bracket up and down.The upper and lower suspension bracket of corona wire connects by upper and lower suspension rod.Passing anode at following suspension rod, to restrain locational anode tube be oblong, and oval major axis equals the diameter and the following suspension rod diameter sum of two anode tube, and following suspension rod passes from the center of oval pipe.On the long axis direction in oval pipe, the both sides of following suspension rod are provided with many corona wires, make down suspension rod and corona wire equal substantially to the distance of oval inside pipe wall.In cylindrical shell, the outside of precipitation anode tube, on cavity between the lower perforated plate be connected with vapor source by vapour inlet.Anode tube connects the positive pole of power supply, the negative pole that cathode line connects power supply.One conical loam cake is arranged at the top of cylindrical shell, covers and is provided with feeder box; Spray equipment is housed in the loam cake.The cylindrical shell bottom is the taper ash bucket, and the pitch coke wet goods that precipitation is collected is discharged thus.On the going into of electric cleaner, exit and auxillary flue, chain electrically operated valve mutually is housed, and is subjected to the control of temperature sensor.
Each unit of this deduster all is one group of pipeline electric cleaner, and the corona negative electrode connects the negative high voltage of high-voltage suppling power, and receiving electrode connects positive pole.Between pipeline, produce a uneven electric field,, be far longer than electric-field intensity near the tube wall place near near the electric-field intensity the cathode line.After supply voltage is elevated to certain numerical value, will produce corona discharge near the lead, a large amount of anions that produced in the corona layer under the effect of electric field force, to the tube wall motion, make the neutral molecule ionization in space again fast in the motion.Because the anode tube that following suspension rod passes is oblong, there are many corona wires the centre, and following suspension rod and corona wire are equal substantially to the distance of anode tube inwall, can make deduster realize full-ionization.When dust-laden (tarvia droplet and dust) gas from down and during the non-uniform electric field the pipe of flowing through, because collision and diffusion, make powder dust particle charged, powder dust particle after charged is subjected to the effect of electric field force and moves to the tube wall as anode, arrive and electrically to neutralize behind the tube wall and be deposited on the tube wall, relying on measures one's own ability or shake falls into ash bucket.Because the pitch coke oil viscosity is bigger, can not fall automatically, so at the logical high-temperature steam in the outside of anode tube, make anode tube and be higher than the softening point temperature of pitch by the flue-gas temperature of anode tube, make the tarvia that is deposited on the tube wall, owing to be in softening flow regime, trickle in the ash bucket of bottom along tube wall.Spray equipment can clean the precipitation anode at any time and put out a fire explosion-proof.When input gas temperature surpasses predetermined temperature or deduster internal fires, can be at any time according to the instruction of temperature sensor, conversion valve changes flue gas over to auxillary flue, realizes interlock protection.Or explosion-protection equipment opens automatically, and the accident that prevents takes place.Purified gas is discharged from the top of deduster.
The utility model has the advantages that, adopted the allocation plan of best anode tube and cathode line, make the discharge inception voltage unanimity of each clean unit, guaranteed best efficiency of dust collection; Adopted heating, insulation and automatic temperature control and charged spray equipment can guarantee the cleaning of electrode and long-term stable operation, when flue-gas temperature is too high, can automatically flue gas be changed over to auxillary flue and discharge, and be provided with explosion-protection equipment, and the accident that prevents takes place.
Accompanying drawing 1 is a structural representation of the present utility model, and (1) is exhanst gas outlet among the figure; (2) be feeder box; (3) be upper hanger; (4) be spray equipment; (5) be upper perforated plate; (6) be over sling; (7) be the precipitation anode tube; (8) be the cathodic electricity hachure; (9) be following suspension rod; (10) be that cylindrical shell (11) is a vapour inlet; (12) be lower perforated plate; (13) be following suspension bracket; (14) be weight; (15) be smoke inlet; (16) be gas distribution grid; (17) be explosionproof hole; (18) be the tar outlet.
