Abstract
The present invention relates to carbon smoke particle filter for diesel engine exhaust gas, which comprises a metal shell, filtration units which are covered with a metal screen on a metal bracket, a high voltage direct current supply, an air inlet pipe, a small exhaust pipe and a main exhaust pipe, wherein the adjacent filtration units are electrically connected with two poles of the high voltage direct current supply, and fixed in the metal shell through insulators. Clean gas which is filtered by the metal screen is exhausted from the main exhaust pipe through a gas collecting chamber; the other part of gas and charged carbon smoke particles are exhausted from the small exhaust pipe, can carry out secondary filtration and can also circularly enter a cylinder to be burnt. The present invention is characterized in that fume is divided into the clean gas and gas of high carbon smoke concentration. The present invention has the advantages of continuous filtration, no clogging, no need of regeneration and long service life.
Description
Technical field
What the present invention relates to is a kind of diesel exhaust gas purifying device, particularly a kind of diesel exhaust gas soot particle filtrating equipment that is applied to.Belong to dynamic power machine and environmental technology field.
Background technique
Contain multiple harmful material in the diesel exhaust gas soot particle, environment is caused severe contamination.Exhaust smoke abatement apparatus in the prior art mainly contains following several:
The one, media filtration, media regeneration then.Number of patent application is that 99250866.5 diesel engine vent gas particulate processor is to adopt ceramic filter, the carbon-smoke combustion regeneration of adopting microwave to make discontinuously to be deposited in the pottery.This device can cause plugged filtration media.Number of patent application is that 00243230.7 a kind of reverse jet regenerating diesel engine carbon black filter is to adopt media filtration, adopts the pressurized gas pulse cleaning then, and this method filter efficiency and the pressure loss all change all the time.
The 2nd, media filtration is catalytic oxidation simultaneously.Problems such as plugged filtration media, catalyst failure easily take place in this method.
The 3rd, liquid cleans.This mode purification efficiency is low.
Summary of the invention
Be deficiency and the defective that overcomes prior art, the present invention designs a kind of diesel exhaust gas soot particle filtrating equipment.This filtrating equipment comprises metal shell, little outlet pipe, main exhaust, gas collection chamber, Steel Support, metal screen, insulator, high-voltage DC power supply.Metal shell be open wide above a kind of, about for platform shape changeover portion, middlely be the housing of cuboid, the two ends of metal shell link to each other with suction tude, little outlet pipe respectively.Be parallel in the middle cuboid of metal shell some filter elements axially are housed, filter element is made up of Steel Support and metal screen, Steel Support is the cuboid frame that is welded into by metal bar, on Steel Support two facades vertically, cover metal screen, filter element is except that two facades of end face and covering metal screen, and other three side sealing closes.Between filter element upper and lower surface and the metal shell insulator is housed, adjacent filter element is electrically connected with high-voltage DC power supply the two poles of the earth respectively.Gas collection chamber is contained in the end face of metal shell, and its inner chamber communicates with the filter element inner chamber.Main exhaust communicates with gas collection chamber.
The gas that contains soot flows into the passage between the filter element, and the part clean gas of net filtration after filtration enters in the filter element, and the clean gas in each filter element is pooled to gas collection chamber, discharges through main exhaust.The gas of another part filtered directly passes the passage between the adjacent filter element, discharges from the float tracheae.The soot particle that is intercepted on the filter screen is charged under the effect of high-tension electricity, and leaves filter screen, discharges from the float tracheae with air-flow.Thereby Primordial Qi is separated into clean gas and high-carbon smoke density gas.The high-carbon smoke density gas circulation of discharging from the float tracheae enters engine combustion, or carries out secondary filter.
The present invention utilizes high-pressure electrostatic to make carbon granules charged, and carbon containing flue gas body is separated into clean gas and high concentration gas, but high concentration gas secondary filter, and the motor that enters also capable of circulation is burnt soot.This device can be identical working life with motor.Filtration resistance is low, but continuous operation need not regeneration.
Description of drawings
Fig. 1 is a filter apparatus configuration principle front view of the present invention.
Fig. 2 is an A-A cross-sectional view among Fig. 1.
Fig. 3 is the top view of Fig. 1 along the axis horizontal section.
Among the figure, the 1st, suction tude, the 2nd, metal shell, the 3rd, little outlet pipe, the 4th, main exhaust, the 5th, gas collection chamber, the 6th, Steel Support, the 7th, metal screen, the 8th, insulator, the 9th, high-voltage DC power supply.
Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described.
As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes suction tude 1, metal shell 2, float tracheae 3, main exhaust 4, gas collection chamber 5, Steel Support 6, metal screen 7, insulator 8, high-voltage DC power supply 9.
The gas that contains soot flows into the passage between the filter element, and a part enters in the filter element through the clean gas that metal screen 7 filters, and the clean gas in each filter element is pooled to gas collection chamber 5, through main exhaust 4 dischargings.The gas of another part filtered directly passes the passage between the adjacent filter element, discharges from float tracheae 3.The soot particle that is intercepted on the metal screen 7 is charged under the effect of high-tension electricity, and leaves metal screen 7, discharges from float tracheae 3 with air-flow.Thereby Primordial Qi is separated into clean gas and high-carbon smoke density gas.The high-carbon smoke density gas circulation of discharging from float tracheae 3 enters engine combustion, or carries out secondary filter.
