Abstract
A cyclone pulse electrostatic water membrane precipitator is provided, which belongs to an air purifier. A central bracket is mounted in a cylinder and is provided with discharge electrodes; the discharge electrodes are connected with HV power supply via cables; HV insulator compartments are arranged on the upper part of air outlet. When in operation, dust gas is led in through the air inlet with airflow ascending aswirl; the airflow throws the dust to the water membrane on the inner wall of the cylinder depending on centrifugal effects on one hand and causes the discharge electrodes to do corona discharge on the other hand, thereby forming non-uniform electric fields between the discharge electrodes and the water membrane on the inner wall of the cylinder to form charge dust collection zones; when the dust gas passes the zones, free electrons, negative ions and dust collide and adhere to the dust gas to realize the charged dust, therefore ensure that the charged dust is driven to the water membrane at higher speed and adheres to the water membrane under the actions of centrifugal force and coulomb force and is discharged by flowing with the water membrane. The collection coefficient of the utility model can reach 99.5 per cent, which can effectively remove micro dust particles, have safe and reliable performance and simple operation and is especially practical to be applied for the reconstruction of the present cyclone water membrane precipitator.
Description
Technical field:
The utility model belongs to air cleaning unit, is that a kind of cyclonic water film deduster improves.
Background technology:
Cyclonic water film deduster is used for the purification in boilers such as industrial heating and dusty gas place, this class deduster tangentially sprays to wall with water smoke by the nozzle that is arranged on cylindrical shell top, perhaps the spilling water groove by cylindrical shell top makes the deduster cylinder inboard wall form the very thin continuous dirty moisture film of one deck, dusty gas is imported by the cylindrical shell lower tangential, and rotation is risen, and relies on centrifugal action that dust is got rid of to wall, stick on the moisture film, flow down and discharge along wall, thereby reach the purpose of Purge gas, for example the CLS type.But purify for the dusty gas that is positioned at the city proper, such dust removing effects can not reach the environmental protection standard of country's promulgation, and it is very low to the separative efficiency of fine grit especially.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of efficiency of dust collection height, and can remove the deduster of fine grit effectively.
The technical solution of the utility model is to install center bearing bracket in the deduster cylindrical shell, be equiped with discharge electrode on the center bearing bracket, discharge electrode connects high-voltage suppling power by cable, and high-voltage suppling power is the accurate pulse power of super-pressure, on the top of air outlet slit the high voltage insulator compartment is set.During work, dusty gas is imported by air intake, the air-flow rotation is risen, rely on the one hand centrifugal action that dust is got rid of moisture film on cylinder inboard wall, make discharge electrode generation corona discharge on the other hand simultaneously, between the moisture film on discharge electrode and the cylinder inboard wall, form inhomogeneous field, form the electric charge dust collection section, when dusty gas is distinguished by this, free electron, the collision of anion and dust is also adhered on it, has realized the charged of dust, thereby charged dust is accelerated drive toward the moisture film place under the effect aspect centrifugal force and the Coulomb force two and adheres on it, discharge down with water film flow, cleaned gas is discharged by air outlet slit.Because operating temperature is 100-250 ℃, dirty moisture film forms the state that is full of water vapour in deduster, and electric field heteropole distance is 300-800MM, operating voltage is up to 100-300KV, the high voltage insulator compartment works in outside the primary air band high-tension insulator, be in state position, negative pressure dead band, kept good High-Voltage Insulation characteristic.Discharge electrode is in the wind field with certain speed, can realize its natural deashing.
Owing to contain the sulfur dioxide composition in the coal-fired flue-gas more, be equiped with the jet sprayer at the air intake place, during use, in the jet sprayer, add desulfurizing agent, can improve the sulfur dioxide removal rate effectively, reduce the ratio resistance and the dust concentration that enter the deduster dust simultaneously, improved the charged condition of dust, further improved the efficiency of dust collection of equipment.
The utility model dust removal efficiency can reach 99.5%, can remove fine grit effectively, and performance is safe and reliable, and is simple to operate, is particularly useful for existing cyclonic water film deduster transformation.
