Description
2~87283 Title of the Invention:
APPARATUS FOR REMOVING BLACX SMOKE OF EXHAUST GAS FOR
DIESEL ENGINE
Back~round of the Invention:
This invention relates to an apparatus for removing black smoke of exhaust gas for a diesel engine and, more particularlyr to a black smoke removing apparatus for efficiently removing black smoke.
Description of the Prior Art:
A great deal of black smoke of incompléte combustion is included in exhaust gas from a diesel engine. However, since this black smoke affects remarkably adverse influence to a living body system, it has been tried to eliminate production of the black smoke from the engine itself, but it is technically very difficult, and hence this problem is not yet solved.
Therefore, a technical subject to be solved must be studied so as to efficiently remove black smoke produced from a diesel engine, and an object of this invention is to provide an apparatus for removing black smoke of exhaust gas for a diesel engine which solves the technical subject described above.
Summary of the Invention:
The present invention has been proposed so as to perform the above-described object. There is provided an 2~872~3 apparatus for removing black smoke of exhaust gas for a diesel engine comprising an exhaust gas tube mounted longitudinally at one side of a cylindrical housing, an air intake tube mounted longitudinally at the other side of the housing and connected at one side to an engine, a filter having a number of pores formed at positions opposed to the exhaust gas tube and the intake tube and rotatably mounted in the housing, and a pressure air pressure feeder arranged at the intake tube side for feeding pressure air produced by a compressor under pressure.
Exhaust gas discharged from a diesel engine is introduced into a housing through one exhaust gas tube.
The exhaust gas is discharged externally from the other exhaust tube through the pores of the filter slowly rotated in the housing. At this time, black smoke (fine particles) included in the exhaust gas is adhered to the pores of the filter in a clogged state, and only exhaust gas of complete combustion is discharged externally. Further, since the filter is slowly rotated, when the filter is rotated to the intake tube side of the other side, black smoke of the clogged state in the pores of the filter is forcibly separated from the air to be sucked from the intake tube for the atmosphere. The black smoke separated from the other intake tube connected to the diesel engine is circulated together with the air to the diesel engine, and ~087~3 again burned in the engine. At this time, compressed air produced by a compressor is fed under pressure tu the intake tube, and hence black smoke adhered in the clogged state in the pores of the filter is almost completely separated by the aid of the pressure air, fed under pressure from the other intake tube to the diesel engine and burned.

Detailed Description of Preferred Embodiments:
An embodiment of the present invention will be described with reference to Figs. 1 to 6. In the drawings, reference numeral 1 denotes a housing. The housing 1 is formed in a cylindrical shape, and exhaust gas tubes 2 and 2 are respectively mounted oppositely to each other at one sides of a front wall la and a rear wall lb thereof.
Further, intake tubes 3 and 3 are respectively mounted ~872~3 oppositely to each other at the front wall la and the rear wall lb of the other side of the housing 1. Accordingly, the exhaust gas tubes 2 and the intake tubes 3 are respectively mounted at the relative positions of the front walls la and the rear walls lb in a linear direction.
A filter 4 which can be slowly rotated along an inner peripheral surface of the housing 1 is journaled at a shaft 5 in the housing 1. In addition, a number of pores 4a, 4a,.. are perforated at positions of the filter 4 oppositely to the exhaust gas tubes 2, 2 and the intake tubes 3, 3 in the longitudinal direction of the peripheral surface thereof. Accordingly, the pores 4a, 4a,.. are not opposed to both the exhaust gas tubes 2, 3 and the intake tubes 3, 3 upon rotation of the filter 4.
The exhaust gas tube 2 and the intake tube 3 mounted at the front wall la side of the housing 1 are coupled to a diesel engine (not shown), and the exhaust gas tube 2 and the intake tube 3 mounted at the rear wall lb side of the housing 1 are opened with the atmosphere side. Further, the intake tubes 3, 3 are constructed to be adapted to suck the atmospheric air at a high speed and to feed the air to the diesel engine. Then, in order to increase the air intake power of the atmospheric air, an approximately semicircular pressure air chamber 6 is mounted along the outside surface of the intake tube 3 of the opposite side ~872~3 to the diesel engine. Then, the pressure air chamber 6 has a pressure air guide hole 6a at a center thereof, is opened at 6a on the front surface thereof. A short tube 7 protrudes fxom a center of a back surface side 6c of the pressure air chamber 6, and a hole 9 coupled to a compressor 8 is connected to the short tube 7. Further, a switching vale 10 and a kimer 11 are mounted on the way of the hose 9, and constxucted to be adapted to control the pressure air fed under pressure by the compressor 8.
The pressure air chamber 6 is contacted at the bent inner surface thereof along approximately half the side of the intake tube 3 protruding from the rear wall lb of the housing 1, and fastened at the upper and lower surfaces to the rear wall lb of the housing 1 by bolts 12 and 12.
Further, a number of nozzlelike holes 13, 13,.. are perforated at the rear wall lb of the housing 1 oppositely to the opened portion 6b of the front surface of the pressure air guide hole 6a of the pressure air chamber 6.
The holes 13, 13,.. are formed in a semicircular shape, and when the filter 4 is rotated, the holes 13, 13,.. are provided at the side through which all the pores 4a, 4a,..
formed at the filter 4 are passed.
The gas from the holes 13, 13 of the rear wall lb of the housing 1 is fed under pressure to a space 14 form~d in the housing 1. The atmospheric air supplied from the intake 2~g7283 tube 3 is also guided to the space 14, and the air is fed under pressure together with the pressure air to the pores 4a, 4a,.. of the filter 4. The opened portion 6b of the front surface of the pressure air chamber 6 is disposed nearly directly on the front surfaces of the pores 4a, 4b,.. of the filter 4, and the pressure air in the pressure air chamber 6 may be fed under pressure directly to the pores 4a, 4a,.. of the filter. The space 14 is formed by a partition wall 15, and sealed by a seal 16. A space 14a similar to the space 14 is also formed at the opposite side, and sealed by a seal 16a. Reference symbol 16b denotes a seal provided on the inner peripheral surface of the housing 1, and numeral 17 denotes bearings.
As described above, exhaust gas discharged from the diesel engine is introduced into the housing 1 through the exhaust gas tube 2. The filter 4 is provided in the housing 1, and a number of pores 4a, 4a,.. are perforated at positions opposed to the exhaust gas tube 2 in the filter 4. Accordingly, the exhaust gas introduced into tha housing 1 is discharged from the other exhaust gas tube 2 communicating with the atmosphere through the pores 4a, 4a,.. of the filter 4 to the atmosphere. At this time, if black smoke of incomplete combustion is mixed within the exhaust gas, the black smoke is adhered to the inner walls of the pores 4a, 4a, .. of the filter 4 in a clogged state ~728~
when the black smoke tends to pass the pores 4a, 4a,.. of the filter, and not almost discharged into the atmosphere.
Further, since the filter 4 is slowly rotated, the black smoke adhered to the pores 4a, 4a,.. of the filter 4 in the clogged state is rotated to the positions of the intake tubes 3, 3. Thus, since the intake tubes 3, 3 suck the atmospheric air at a high speed, the black smoke adhered to the pores 4a, 4a,.. of the filter 4 in the clogged state is forcibly separated by the pores 4a, 4a,..
of the filter 4 by means of the sucked air, fed together with the sucked air to the diesel engine through the intake tube 3 mounted on the front wall la of the housing 1, and burned in the engine. At this time, since the pressure of the air sucked from the intake tube 3 is low, it is considered that the black smoke clogged to the pores 4a, 4a,.. of the filter 4 cannot be separated. In such a case, compressed air by the drive of the compressor 8 is fed to the pressure air chamber ~, the pressure air is fed under pressure from the space 14 to the pores 4a, 4a,.. of the filter 4, the black smoke clogged to the pores 4a, 4a,.. of the filter 4 is completely separated, fed to the diesel engine through the intake tube 3 of the other side, and burned in the engine. The operation as described above is repeated to again burn the black smoke in the exhaust gas of the diesel engine and to discharge it to the 2~872~
atmosphere. Accordingly, various types of public pollution of the black smoke can be removed. This invention may also be applied to removal of oil smoke of a two-cycle engine.
According to the present invention as described in detail above with respect to the embodiment thereof, the black smoke of the e~haust gas discharged from the diesel engine is collected by using the filter, the black smoke clogged to the filter is separated by the pressure air, sucked, again fed to the diesel engine, and again burned in the engine. Therefore, public pollution by the black smoke in the exhaust gas of the diesel engine can be prevented, thereby providing remarkably advantageous effect.
The present invention may be variously modified within the scope of the spirit of the present invention, and the modifications thereof will be naturally included in the scope of the present invention.
