Description
The present invention relates to a kind of vertical drum type electrostatic precipitator.
The structure of original vertical drum type electrostatic precipitator is cylindrical shape, and the cathodic electricity corona wire is set at home position, its main starting point is to bring up a uniform electric field in cylindrical shell, in order to strengthen the flue gas treating capacity, enlarge field area, often take to strengthen the way of bobbin diameter, but this measure is produced effects not quite to enlarging field area, because enclosing under the condition of certain area surely, the girth of justifying is the shortest, also have and adopt a plurality of cylinder parallel connections, but can't solve the airflow uniform distribution problem between each well, influence the performance of ability of gathering dust, and bring investment to increase, occupied ground is big, and various auxiliary equipment are many, complex structure, the shortcoming of installation and maintenance difficult.In addition, the cylinder rigidity is fine, is unfavorable for vibration dust-cleaning, and dust is stained with the inwall circular arc and is produced " interior arch ", has strengthened the adhesive force of dust and wall.Sheet material utilizes paper, waste steel when making circular flange.The at present domestic ZD type combination electrostatic precipitator of promoting the use of, adopt inside and outside sleeve, dusty gas enters inner core from top earlier, change the space between the inside and outside sleeve again over to from the bottom, extract out from top again, though this measure has increased field area to a certain extent, but gas has changeed twice more to be bent, vapour lock increases, and pay considerable electricity charge because of fan energy consumption increases every year more, and its inner core is big because of dust concentration, cause corona blocking, influenced dust collection effect greatly, first dust suction on the mechanism of action polarizes to dust again, succession is put upside down, practical example shows, this kind deduster the corona current of load condition only reach Light Condition 1/4th a little less than, be in the corona blocking state in fact.
The purpose of this invention is to provide that a kind of field area is big, few, the good C-V characteristic of the airflow uniform distribution vertical drum type electrostatic precipitator good and easy for installation of consumption steel.
The present invention is made of outer cover, inlet and outlet, rapping machine, ash bucket, insulator, ash-valve, clamp flange, the anode tube that a plurality of cross sections are square is contained in inside, shared its spaced walls of adjacent anode tube, place clamp flange in the integral outer that described a plurality of anode tubes are combined into, one cathodic electricity hachure is arranged in each anode tube, each corona wire is fixed together with connector respectively at top and bottom, and rapping machine is installed on the connector of described top.
Have intercommunicating pore on the common wall of adjacent anode tube.
Shelves are then supported in four fillet welding of anode tube, and the support shelves in each bight form a line from top to bottom.
Be provided with one group of anode guide plate and negative electrode guide plate in the ash bucket, described anode guide plate, cloudy plate guide plate are all arranged downward vertically from the ash bucket upper limb, the anode guide plate that occupies central authorities is the longest, the length of all the other anode guide plates is successively decreased successively according to its distance apart from central authorities, an air inlet is respectively arranged in the ash bucket both sides, in the middle of the adjacent anode guide plate negative electrode guide plate is arranged, the negative electrode guide plate is connected with corona wire electricity.
Air outlet is a big down narrow air-suction cover, and the vertical distribution area that is projected on each anode tube of this air-suction cover equates.
The cross section of corona wire is a flattened rectangular, and laminar discharge electrode is housed, and the plane at described discharge electrode place is perpendicular to ground, and its end respectively has two spines, and each spine points to different directions.
Advantage of the present invention is to have broken the necessary notion uniformly of the electric field of thinking traditionally, electrically charged own according to soot dust granule and institute with regard to the uneven fact, be designed to the anode tube square, allow internal electric field to have to a certain degree inhomogeneous, be convenient to make and assembly unit, shared its spaced walls of each adjacent anode tube has been saved steel, but all dust suctions of this spaced walls two sides have enlarged field area greatly and have complied with strange formula according to the leading of dust collection efficiency of relevant electrostatic precipitator:
η＝I-e
-ωf
Wherein: η: dust collection efficiency
ω: flue dust migration velocity
F=(A)/(Q), A: field area, Q: flue gas flow
Field area of the present invention is more many greatly than the cylindrical shape deduster with similar appearance and size, has correspondingly improved efficiency of dust collection and flue gas treating capacity.Simultaneously, the engineering the present invention who finishes an equal flue gas treating capacity will be little more many than the appearance and size of cylindrical shape deduster, and save complicated flow distributor, many circular flanges and auxiliary equipment, more compact, easy for installation on the structure, reduce investment outlay and floor space.
The present invention by open on the spaced walls between each anode tube intercommunicating pore solved many cylindrical shells deduster the tube between the uniform difficult problem of flow, if mass flow discrepancy, then since the formed pressure differential of flow velocity difference will make flue gas from high flow capacity the tube flow to low discharge the tube.
The setting of supporting shelves not only helps strengthening bulk strength, help also that resistance is loose, steering current promotes between tube and in the tube air velocity even.
The present invention has arranged the air inlet of one group of anode guide plate and negative electrode guide plate and two correspondences in ash bucket, at first flue gas is polarized, be convenient to capture in the tube, improve efficiency of dust collection, positive plate median plate block length, the short structure in both sides help air-flow and enter a plurality of anode tubes equably simultaneously, make the uniform degree of air-flow better.
The wall of square anode tube produces rational vibration frequency and amplitude than the easier excitation of cylinder, help vibration dust-cleaning, and cylindrical shell keeps suitable intensity and stability on the whole.
Traditional electrical hachure cross section is circular, and be used to apart from bigger in its cross section, and rapping can the section difficulty be converted into high frequency waves, and deashing property is poor, because corona wire length is bigger, integral rigidity is little, easily produces low frequency and significantly vibrates, and influences die opening, causes " wire jumper ".Corona wire of the present invention is in horizontal being used to apart from less, and vibration performance is good, and arranges the reinforcement integral rigidity by the connection between each corona wire, prevents that " wire jumper " phenomenon from taking place.
The tradition very wire nail shape that discharges, its self-excited oscillation poor performance, vertical perspective plane is big, and dust stratification " dross " causes corona blocking easily, laminar prickle self-excited oscillation function admirable of the present invention, deashing property is good, and vertical perspective plane is little, is difficult for dust stratification, corona current is more even in the distribution of circumferencial direction, makes dust-precipitator have good C-V characteristic.
