Abstract

The invention relates to a purification system for purifying gases and trapping and recycling all particulates produced by internal combustion engines, which system is formed by three individual bodies, with the action of the first body impacting on the second body and the action of the second body impacting on the third body. A) A water chamber integrated into the exhaust tube with a replacement radiator and a closed-circuit water pump. B) A particulate-trapping reforming silencer. C) A cylindrical device having rotary filters which are dipped in a basic solution by means of an axle that is placed at the centre of the side covers and a motor for the rotation thereof. The gases enter through the aforementioned covers by means of a two-part tube which divides the gases towards each end. A stabilising chimney extends from the centre of the surface of the cylindrical device and the last segment of the exhaust tube is coupled therein. In addition, an elongate particulate recycling container and a drum of liquid solution are provided in the lower part of the cylindrical device.

Description

Gas purifying system, trapper and recycler of all particulate emitted by internal combustion engines; all by means of a cooling chamber, a refurbished silencer and a device with interior filters that rotate bathed in a basic solution.

Background of the Invention

The present invention is a gas purifier, trapper and recycler system for all fine and ultra fine particles from internal combustion engines; Applicable to trucks, buses, cars, agricultural, mining and earthmoving machinery (works and works). Pollution in cities is today, the big problem that affects us all, and this is mainly due to the large increase in internal combustion vehicles, such as cars, trucks and buses.

To solve this problem, various devices have been proposed to avoid the contaminants or residues that these internal combustion engines launch into the environment. One of these proposals to decontaminate is the invention patent (Chilean) No. 34.026 of February 24, 1984, which consists of a tank connected to the exhaust pipe, divided into two chambers with trays, both with a basic solution consisting of water with burned oil, so that when harmful gases present in the air enter the first chamber, these are divided into small bodies, by means of a tray with holes; With the pressure expelled by the engines, these gases are submerged in the liquid to pass, then, to the second chamber, also divided by a tray equal to that of the first chamber, in addition said second chamber carries 3 outlet tubes to decompress the pressure which usually comes out of a single tube, also the tank is crossed under the level of the basic solution, by 3 tubes whose objective is to cool said overheating solution that would suffer with the hot air of the engines.

Although this system represents an attempt to retain contaminating particles, it suffers from several points, which are at the expense of its optimal function. On the one hand, the gases, when they pass through the floating oil on the water, make it like small bubbles, however the internal empty body of each bubble is not enough to wash with the basic solution, this results in that it cannot be suppressed A good percentage of pollution. On the other hand, the pipes that necessarily cross the tank through its lower section, with the purpose of making a self-cooling of the liquid contained in the tank, would not correctly fulfill their function in the cities, since in summer, the streets with pavements asphalt, mainly, and also concrete ones, overheat with the sun; with the heat that the pavement acquires and the fact that great distances are not traveled within the city, much less the buses or micros of public locomotion, which must stop regularly, and also their

displacement is slow, all this will not work the cooling system.

Then, when the cooling system does not work, the water with oil will overheat and oil emanations that are not pleasant to the senses will go outside, and the heat will cause the water to evaporate quickly.

Another device designed to prevent contamination produced by internal combustion vehicles is described in the (Chilean) patent No. 35,813, which is a gas purifier that is formed by a receptacle connected to the exhaust pipe, divided into 3 chambers, one of them with a basic solution consisting of bicarbonated water, such that the entry of gases into the first chamber is produced under the basic solution, by a series of perforations in the extension of the exhaust pipe; then, from this first chamber the gases pass to the second chamber, the one that has two trays with perforations not coinciding with each other, and by said perforation the air-gases are divided to pass to the third chamber composed of 2 filters, the first is of metallic chip or bast, and the second, of activated carbon.

Although this system has a greater number of chambers and filters that purify the gases, it presents, like the previous system, functional problems, there will also be contaminant particles in the basic liquid, but the liquid will not trap the contaminants that go in the center of the bubbles, in addition, the basic liquid will overheat so much that its evaporation will be extremely fast; thus, the contaminating particles still dispersed by the second chamber will cause the activated carbon filter to be covered with foreign bodies, whereby the engine will drown.

The present invention is a new system of three individual bodies in which the action of one affects the second and the second in the third, for a greater perception of it, a brief description of the drawings will be made.

DESCRIPTION OF THE INVENTION

As can be seen in Figures 1 to 9, the invention consists of a gas purification system and pollutant eliminator of internal combustion engines; Contaminants such as fumes, particles, toxic, charcoal and bad odors in general, and whose system is formed in a first stage:

A.- Through a water pump (1) that circulates cold water through a duct (2) to the inlet (3) of a sealed chiller chamber (4) connected to the exhaust pipe (5) in such a way that It becomes a section of it, inside and along it presents several tubes (6) separated from each other where the gases pass, which lower their temperature by the action of cold water that in turn heats up, then, by the water outlet (7) of said cooling chamber (4) and through another conduit (8) the hot water arrives at a radiator (9), where it again cools, and finally through another conduit (10) the cold water from the radiator (9) to the pump (1); This closed circuit has a small reservoir or reserve drum (11), which, through a conduit (12), carries water to the pump (1).

B.- Backwards in the exhaust pipe (5) is located the silencer (13) of the exhaust pipe (5) which occupies only 50% of its capacity, due to the arrival of the gases from the exhaust pipe (5) is from the top of the silencer (13), and the output is made on the opposite side of the silencer (13) but from its bottom side, and with a normal exhaust pipe outlet (5), so that water from the condensation of the chiller chamber (4) accumulates.

C- The third stage consists of a cylindrical housing (14) located near the last section of the exhaust pipe (5) whose Diameter is twice the exhaust pipe (5) and has an inclined tank or canoe (15) longitudinally attached in its lower area that has a drain plug in its lower part, (16) said cylindrical housing (14) communicates internally with the canoe (15) by means of a row of perforations (17); From the spine of the cylindrical housing (14) a stabilizing chimney (18) protrudes centrally, from which the last section of the exhaust pipe (5) emerges, while at the base (19) of the chimney (18) is I insert the tube (20) where the liquid solution arrives, (21) which ends inside the cylindrical housing (14) in an acute form and submerged in said liquid solution (21), and the level tube (22) and investment of element (air / water) that is also based on the base (19) of the chimney (18) is what defines the level of the liquid solution (21); the liquid solution arrives from a drum (23) that is near and on the cylindrical housing (14); The covers (24) are fitted or sealed at the ends of the cylindrical housing (14) by means of an orings (25), each cover (24) has a plastic bushing (27) in its inner center (26). the covers (24) have a gas inlet (28) transversely with respect to the cylindrical housing, (14) this gas inlet (28) is at an upper side end of the cover (24), but the outlet ( 29) Gas from the covers (24) towards the inside of the cylindrical housing (14) is linearly with it; the shaft (30) that longitudinally crosses the cylindrical housing (14) and that is supported by the side covers (24), has grilles or filters (31) in each side section of the shaft (30) and in the longitudinal center of the shaft ( 30) goes a solid body (32) or circular brass that rotates together with the shaft (30) and filters (31) so that the torrent of gases coming from each cylindrical housing end (14) does not collide with each other, but that join when they reach the chimney (18) stabilizer; the filters or grilles (31) are separated from each other by individual separators (33), and at the ends of the shaft (30) there are masses (34) that compact and maintain the filter body (31); in one of the side covers (24) of the cylindrical housing (14) the base (35) that holds the motor (36) lowered in revolutions is attached which rotates the central axis (30) of the cylindrical housing (14) by means of pulley (37) and a belt (38); the gases reach the cylindrical housing (14) through the lateral inlet (28) of the covers (24) of the cylindrical housing (14), by means of a duplex tube (39), which equitably, due to a stage (40) element divider, located in the central fork (41) of a section of the exhaust pipe (5).

A brief description of how the system works will be made:

A. - A water pump, which circulates cold water to an airtight chamber, connected to the exhaust pipe, through which the gases pass, which lower their temperature by the action of the cold water that in turn heats up.

Then, through said chamber, hot water flows to a radiator, from where, again, cold water returns to the water pump; This closed circuit carries a reserve water tank to maintain an absolute full.

B. - Backwards, in the exhaust pipe there is a recycler silencer that fulfills its original mission by 50% and the other 50% is to recycle in its humid interior walls, the physical contaminants that are now wet will move backwards.

C- Towards the end, near the last section of the exhaust pipe is a tank or cylindrical housing, in which a mechanical device consisting of an axis with meshes or grilles that rotate bathing in a liquid solution, whose central axis is mounted it is supported by the end caps of the cylindrical housing; On one side of one of the covers is the motor that rotates the shaft with its body of meshes and the brass divider; on the surface of the cylindrical housing there is a chimney from which the last section of the exhaust pipe comes out; in its lower part there is a canoe collecting pollutants; gases and pollutants reach the cylindrical housing by means of a duplex tube connected laterally to the covers; When the impure and contaminating gases reach the inside of the cylindrical housing, they are trapped in the moisture of the filters, and when immersed in the basic solution they remain in the water.
