SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention.
This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.
This invention discloses the design and construction of a device that removes soot particles from an exhaust gas of an internal combustion engine and then converting the collected carbon into finished material such as carbon paper.
This method uses an electrostatic precipitator which uses corona discharge that generates from high voltage pulse to excite the electric field between electrodes of electrostatic precipitator. From a comparative study of the field exciting between high voltage pulses energizing and high voltage direct current energizing, it was found that high voltage pulse energizing not only used lower energy but also had higher efficiency. After the electric field is set up, the gas particles flowing through the electrodes gets ionized and charged particles will move to collector plate due to electrostatic force. The particles are then moved from collector plate to further processing. The soot particles are mixed with melted wax and oil in mixing chamber accordingly. Then a paper roll is dipped through this mixture and placed at low temperature area so that the paper and mixture stick and cool down. Then the paper is collected into a separate area and can be taken out from there.

Diesel particles consist of a complex mixture of elemental carbon (EC), hydrocarbons (HC), sulfur compounds and others compound. They differ in term of size, composition, solubility and other properties. The compositions of particle from diesel engines are shown in Figure 1. Some of them are in volatile and the volatile fraction is depending on the temperature and other conditions. Some may remain in the gas phase or condense on existing solid particles or nucleate and form new particles.
This method uses electrostatic precipitator as a filter to remove particulate matter from the exhaust fumes.
ESPs are the most common particulate emissions control device which is widely used in coal-fired power plants and industrial. An electrostatic precipitator uses a high voltage pulse to discharge electrodes, generating a corona discharge to excite the electric field between electrode gaps.
ESP works when the air flows into the ESP, it will create high voltage electric field generated by a wire and electrode. The negative and positive component form when the gas is ionized. Thus, negative ions will move in the electric field, creating an electric current between the electrodes. Some of the ion will diffuse to the surface of particle and charge them. Charged particle will migrate to collecting plate due to electrostatic force. Therefore, the particle will deposit on the collecting electrodes.
Formation of the corona is to ionizable gas near the electrode and also creates a strong electric field in order to energize the molecules. Usually, the compounds in the air are easily ionized by a strong electric field either in polluted or clean air. In electrostatic corona many chemical reactions occur, which produce a current in positive and negative ions for a normal air in electrostatic corona. The electrostatic can be created with both negative or positive voltages the negative corona is preferred as negative corona typically produce twice current compared to positive corona allowing the chemical reaction to occur fluently. The type of the corona and the charge that will be imparted to the particle depends on the polarity of the discharging electrode. The corona will produce negative ionic current when the discharge electrode is negative and travel from discharge electrode to the collecting electrode through air gap. In contrast, the corona will produce positive ionic current when the discharge electrode is positive and travel from discharge electrode to the collecting electrode. The charged particles interact with the electric field, producing a force which forces them to the collector plate where they are collected.
ESPs are operated near the sparking limit, that is, corona voltage is continuously adjusted to maximize the collection efficiency. This is normally achieved at the sparking rate of 10–50 sparks per minute. Sparking occurs mostly in the front section(s) of an ESP. In the case of high-resistivity (>1010 O cm) dust, special techniques must be used to avoid the formation of back corona. This requires sophisticated systems for controlling corona voltage and current. The formation of back corona can also be reduced with intermittent or low-frequency energization. This technique is based on the extension of the time period between corona current bursts. Thus, much higher current bursts can be used without causing back corona.
The quantity of charged given to the particle is effect on the ability of an ESP to remove suspended particles. Particle charging is a function of ionic current produced by the electrodes in which depend on the voltage of ESP is operated.
The main fundamentals for designing ESPs are: The first one is Onset voltage which is the lowest voltage different across the electrode to start the ionization of air molecules and produce ionic current, the lowest acceptable voltage for the formation of a corona, the electric discharge produces ions for charged particles. The second one is the sparkover voltage which is the highest voltage that produces steady current output in ESP. The third one is the voltage current relationship. Other factors on which efficiency depends upon are gas flow rate and collecting surface of collector.
