Description
Technical field
The present invention relates to a kind of high voltage pulse power power supply, particularly a kind of electric precipitation high-frequency impulse power power-supply.
Background technology
In recent years, along with country strengthens the management of atmosphere pollution, the environmental emission standard of enterprise is also in raising, and a lot of industrial flue gas cleaning equipment does not all reach new standard, faces the situation of secondary transformation.The main flue gas purifying equipment of existing market is electric cleaner.And electric cleaner power supply is as one of the critical component of electric cleaner, it has important impact to dust removing effects, energy consumption, job stability, security.Existing market main power source is three phase mains and high frequency electric source.
Electric cleaner is the equipment utilizing dust granules thing in high voltage electric field purifying smoke.The gas cleaning process of electric cleaner divides three phases: 1, gas ionization and dust charged: between corona discharge electrode and dust collector pole, apply DC high voltage, make the gas ionization near corona discharge electrode, produce a large amount of negative ions.In corona zone, cation is absorbed in the past by corona discharge electrode immediately, and anion is then because moving to dust collector pole by ordering about of electric field force.2, dust deposit: after Charged arrives dust collector pole, releases negative electrical charge and deposits.3, deashing: dust collection is entered ash bucket.The efficiency of electric precipitation and gas ionization and dust charged blunt connect relevant, gas ionization and dust chargeability directly related with the voltage of deduster electric charge field, voltage of electric field raises and dust chargeability can be made to increase, thus raising efficiency of dust collection.Meanwhile, voltage of electric field is elevated to a certain degree, and electric field flashover can occur.The infringement that flashover is larger to power supply, should avoid as far as possible.So in order to solve the opposition contradiction of efficiency of dust collection and flashover, the way of above-mentioned two kinds of power supplys is similar, namely under the prerequisite that serious flashover (limited number of times flashover) does not occur, improve voltage of electric field as far as possible.So both can ensure the life-span of power supply, can raise the efficiency as much as possible again.
Said method has a defect.The parameter affecting the charged effect of dust granules thing is dust specific resistance, and in flue gas, dust granules thing size kind is different, and its ratio resistance is also different.Dust specific resistance is higher, and charged required voltage is higher.When there is not serious flashover in said method, better to the assimilation effect of low resistivity dust, and the dust absorbing effect of middle ratio resistance is general, and the dust absorbing effect of high specific resistance is poor.So cause the dust removing effects of deduster can not better promote; Or causing dedusting energy consumption significantly to increase for promoting dust removing effects, even shortening the deduster life-span.
On the other hand, from energy consumption angle, in electric precipitation process, the overwhelming majority in the electric energy of dedusting electric field consumption also has neither part nor lot in dust charged, but be directly moved to positive plate from minus plate with electronics form, be equivalent to a large amount of energy and waste in the electric field, the utilization rate causing electric energy is low.
