Description
Technical field
The utility model relates to a kind of cleaner, relates in particular to a kind of electrostatic dust collection equipment of boiler.
Background technology
The operation principle of electrostatic precipitator is basic identical, anode and cathode by equipment produces high voltage electric field, when the gas that contains dust granules passes through high voltage electric field, gas is ionized, bump against at face south pole plate when motion and dust of electronegative gas ion, make the grit lotus with negative electricity, the anode motion is deposited on the positive plate grit under the effect of electric field force.Usually electrostatic precipitator is collected and is removed and floats over airborne solid-state and liquid particles, and static electricity dust catcher is provided with air-inlet grille and the grid of giving vent to anger, and is provided with filter and fan in body.In filter, the rear portion of air-inlet grille is provided with a prefilter that tentatively filters the air inlet dust, and there is the electrostatic precipitation part of an electrical method dedusting at the rear portion of prefilter.But the deduster dust removing effects of this structure is poor, does not have gathering-device.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of electrostatic precipitator is provided, and the influence that it is not subjected to dusty gas temperature, humidity, dust stratification does not puncture, the phenomenon of creepage, short circuit, can keep stable high voltage electric field dust removing effects.
For achieving the above object, the utility model adopts following technical scheme: it comprises housing, is provided with electrode system in the housing, and surface of shell is provided with the electrode vibrator, and electrode system and electrode vibrator are electrically connected.
This product is a feature with electromechanical integration, according to the control of electric field motional impedance, wide pitch structure, the horizontal type electric dust collector that designs at high-temperature process.Housing is the main body of maintaining each parts of deduster, and it is the load-carrying construction of entire equipment, mainly by column, wallboard, end plate, back timber, bottom pressure part, middle part pressure part, diagonal brace, inner aisle etc. are formed up and down.
The electrode vibrator is arranged on the top of housing.The electrode vibrator is connected with each electrode of corresponding electrode system.Be symmetrical set air inlet and gas outlet on the housing, air inlet and gas outlet are horn-like.
Electrode system comprises anode system and cathod system.Anode system is one of critical piece of electric cleaner, is the heart of electric cleaner, and anode system is made up of the anti-swinging mechanism in anode arranged plate, rapping anvil beam and bottom.Cathod system is another critical piece of electric cleaner, also is the heart of deduster, and electrode systems is made up of corona wire, last lower transverse tubule, negative electrode hanging beam, cathode suspension system and anti-swinging mechanism.
The bottom of housing is provided with airlock, and airlock is a handstand cone type structure.Airlock is the dust collection that rapping on the electrode is got off, the bottom with unload ash conveying device and connect.The collected dust of electric cleaner is by airlock with unload ash conveying device and see off.
The electric part of this device is partly mated rationally with body, the overall operation unfailing performance meets specification requirement. adopt the COMPUTER DETECTION technology, detect the electric field motional impedance in good time, power supply rationally, guaranteeing that electric field operates under the high-impedance state works, improve electric-field intensity, improve the suffered Coulomb force of charged dust in the electric field, improve dust migration velocity and dust-collecting efficiency. reduce cost, the price of enhancing product performance ratio. adopt wide spacing design with pole span. owing to strengthen with pole span, corresponding heteropole is apart from also increasing, electric field internal breakdown voltage improves, plate face effective electric-field intensity increases, the corona zone enlarges, and corona is abundant, and the loose phenomenon of corona wire is slowed down. and electric current per unit length is big, plate current density is even, migration velocity improves, and has improved the capture performance of high resistivity dust, prevents back corona phenomenon, help the capture of dust, improve dust removal performance. be convenient to simultaneously install, maintenance, resistance is little, characteristics such as power consumptive province and operation are relatively stable.
Because surface of shell is provided with the electrode vibrator, the inner no rapping moving component of electric field improves the inner space utilization rate.The electrode vibrator places dust remover roof, is isolated from beyond the flue dust, helps the reliability service and the regular maintenance of vibrated system.Pole plate and polar curve are not subjected to fierce cross shear, do not break, not board falling, reliability height, life-span be long.Electric field takes up an area of little along its length, is convenient to arrange.The distribution of vibration acceleration meets pole plate, polar curve to the requirement of dust-collecting and vibrating power on pole plate, the polar curve, can reach ash-removal effect preferably with less rapping power.Can adopt little switched-mode power supply mode, help improving supply voltage.
The subsidiary engine equipment of this device is the high-tech product that new technologies such as computer, communication, measurement are developed.It is applicable to electric cleaner on-line monitoring and management, can realize high-voltage silicon rectification equipment, the low pressure rapping of electric cleaner, the Long-distance Control of unloading equipment such as defeated ash and electrical heating.And can realize closed-loop control by the feedback signal of configuration transmissometer on exhaust pass.Native system is applicable to the every field, particularly power industry of electric precipitation expansion, is the visual plant that improves the electric cleaner automatic control level, reaches guarantor's effect energy-saving run purpose.
This dust arrester is particularly suitable for the kiln smoke abatement and dust control of industries such as fire coal, combusting coal water slurry organic carrier liquid phase boiler, electric power, building material cement, metallurgy, is to keep environment, purification blue sky, high-efficiency reliable hi-tech environment protection equipment.It is not subjected to the influence of dusty gas temperature, humidity, dust stratification, does not puncture, the phenomenon of creepage, short circuit, can keep stable high voltage electric field dust removing effects.
