Translation of "Electrostatic precipitation" in German

However, it has proven particularly advantageous to use electrostatic precipitation for separation.

A process for removing dust free of condensed higher hydrocarbon materials from distillation gases containing condensable higher hydrocarbon materials comprising subjecting said distillation gases to electrostatic precipitation at a temperature above the dew point of said condensable higher hydrocarbon materials.

Dust is removed from distillation gases, particularly from gases from the distillation of oil shale, by electrostatic precipitation at temperatures above the dew point of the oil components, preferably between 470° and 550° C.

The electrostatic precipitation of the fine droplets contained in the exhaust air of the evaporation cooling tower permits the separation of relatively large amounts of liquid with low power consumption and negligibly increased flow resistance in the cooling tower.

Electrostatic precipitation can be carried out as a so-called "silent discharge", but preferably is achieved as a so-called "spray discharge" or "corona discharge".

Known processes for dedusting combustion exhaust gases are carried out on a large scale in practice, and centrifugal separation, filtration and electrostatic precipitation are mainly employed for that purpose.

Precipitation of the particles from the aerosol is effected in the individual embodiments by impaction and/or by electrostatic precipitation.

The condensible parts of the distillation gas are preferably separated out through direct cooling with cold oil, if necessary with subsequent electrostatic precipitation of the oil fog.

It is also possible to remove dust by electrostatic precipitation when the heat required for distillation is added in another manner, such as by means of heated solid materials, through the walls of the reactor, by partial combustion of carbon remaining on the shale, etc., provided that higher condensable hydrocarbons are present in addition to dust in the distillation gas that is generated.

The raw gas is cooled down in a glass tube heat exchanger and a venturi scrubber with simultaneous electrostatic precipitation to approximately 45 degrees Celsius.

As a result, a growth of the fine aerosol particles that is as rapid as possible can be achieved by condensation of water thereon, as a result of which it is ensured that the aerosol particles that have grown in size can be removed from the process gas, for example by electrostatic aerosol precipitation.

In the variant shown deposition of the particles is effected by impaction, but electrostatic precipitation might also be used.

Disadvantages of the higher pressure loss of the fabric filter plant were compensated by a smaller current consumption for the electrostatic precipitation and lower maintenance expenditures.

The solution designed within the framework of this project can be divided into three sections: mechanical cleaning, thermal treatment (agglomeration) and electrostatic precipitation.

When planning and designing the new electrostatic precipitation system, LTA made a conscious decision not to follow the general trend towards low-maintenance mechanical air filters.

Electrostatic precipitation only loses a minimal amount of cooling lubricant during the transition to the gas phase.

Mechanical filtration systems used to offer a benefit due to their significantly lower maintenance requirement: Electrostatic precipitation systems are subject to regular and careful maintenance and cleaning.

I have found, moreover, that the paint and lacquer particles which are deposited by electrostatic precipitation in the filter can be removed from the main body of the air without requiring chemical agents in the wash water utilized to scrub the air and this, of course, provides a reduction or elimination of waste disposal costs and more effective reuse of the paint and lacquer residues which can be recovered from the apparatus for this purpose.
