Description
' B. BARINGOLTZ PROCESS FOR PURIFYING EXHAUST GASES Filed Dec. 8, 1942 INVENTOR Bmmwea BARmaoL-r;
7&4: ATTORNEY.
Patented Oct. 22, 1946 1 Claim.
The invention relates to a device which serves as a silencer and disintoxicator of the escape gases of internal combustion engines, which may be added advantageously at the escape tube of the engine, as it will not only enable to silence the noise produced by the combustion, but also to disintoxicate completely the escape gases, causing thus the disappearance of a highly felt, present inconvenience.
At continuation one constructive way of said device will be specified by means of a preferred example of execution of the invention, wherein Figure 1 is a vertical, longitudinal cut through the device,
Figure 2 a vertical view of the device seen from the left end of Figure 1, and
Figure 3 a similar vertical view of the device seen from the right end of Figure 1.
The novel device to which the invention relates, is preferably cylindrical in shape, although this is not indispensable, and it is composed of a principal chamber 5, wherein is inserted a box 2 of much smaller dimensions, provided with a perforated bottom 3' and reposing within principal chamber I upon frame or pedestal 4. Said chamber 2 will contain a filling 5 which consists of a granulated chemical compound which transforms the carbon oxide of the escape gases into carbon dioxide by catalytic oxidation; for example, it can be made up by a mixture which contains Per cent Potassium chlorate 20 Manganese oxide 20 Iron oxide 201 Copper oxide 20 Calcium carbide 201 In the middle of its top, box 2 is provided with a tube 8 which is doubled so as to fit hermetically with another tube of horizontal position l which passes through the lateral wall 8 of principal chamber I, so as to extend to the escape tube 9 of the motor (not shown), wherewith it forms, for example by means of fianges Ill, an hermetic connection.
Principal chamber I, at the side opposed to lateral wall 8, is closed by a division II. Also said principal chamber I contains more or less up to two thirds of its height and surrounding box 2 and tubes 6 and i, a granulated filling of another chemical compound 32, the purpose of which is to absorb the carbon dioxide which is formed in box 2, as well as the other combustion gases. Said compound may consist for example of a mixture of Per cent Calcium oxide 50 Iron sulphate 20 Caustic soda 30 Division II may be fixed to cylindrical wall I2 or" principal chamber I, for example, by means of a ring I3 combined with a groove I l, wherein equally will be retained a bell 55, in communication with principal chamber I by means of an opening I6 arranged at the upper part of division I I and protected by a metal web IT, preferably somewhat bulging towards principal chamber i. From said opening I6 there parts, descending obliquely, a tube I8 which ends at the center of bell 15 which is left open at its narrow hind-end I9, so that bell I5 forms a chamber 20 wherein a first retention of solid organic particles or corpuscles is produced.
The general body of the device formed in its first part by principal chamber I continues to extend to the other side, containing within its cylindrical walls I2 behind the first bell I5 a second hell 2! wherein first bell I5 encases, occupying the central part thereof with its open end I9. This second bell 2|, contrary to first bell I5, is closed in the shape of a truncated cone by wall 22. This second bell 2! is seated upon a horizontal division 22 which extends to the second body 24, and said second bell 2! furthermore is retained by clamps 25 fixed at 26 to the vertical Wall of said second body 2d.
The second body 24, which just has been mentioned, is fixed hermetically to the general body of the device, for example, by means of a ring 21 which within a groove 21 embraces the doubled ends of both walls of the two bodies, viz. of the general body and of second body 24. Said connecting ring 21 will be divided into halves, being thus unmountable, and it can be adjusted hermetically by means of screwpins so as to form an absolutely hermetic union between both bodies.
This second body 24 contains a retention box for solid particles 29, and so as to retain said box 29 within the interior of body 24, said body, for example, may be provided with soldered legs 28. Said box 29 will have as a wall metal webs 30, and to said walls 3!} preferably an oblique inclination will be given, such as shown in Figure 1. Finally, second body 24 terminates in the outlet tube 3| Wherethrough issue to the atmosphere only completely disintoxicated gases, the run of which through the device from escape tube 9 to said outlet tube 3| it is worth While to describe briefly.
Said gases pass from escape tube 9 of the engine through tube I continued by tube 6 to box 2 wherein they cross the layer of the granulated chemical compound 5, so as to pass through the perforated bottom 3 of said box 2 and get scattered, raising from pedestal 4 through the second layer of the other granulated chemical compound 32, so as to pass through opening I6 of division I I to tube I8, wherefrom, issuing at I9, they will 3 hit against back wall 22 of second bell 2|. These runs and hits will provoke the precipitation of the solid particles which accumulate at bottom 20 of first bell l5, as well' as beneath second bell 2|, whereas the light parts, viz., the gases, will raise along the upper wall of second hell 2! so as to pass to second body 24, wherein again they will meet with metal web walls 30 which serve for retaining the last solid particles which may have reached until there. To said. walls 30 the oblicuous inclination shown in Figure 1 has been given so as to lessen the hit of the gases against said walls 30, and, finally, after having passed also through said two walls 30, the purified gases, made innocuous, will escape through outlet tube 31.
I claim:
A process for purifying the exhaust gases from internal combustion engines, which comprises first treating said gases with an agent consisting of the following components in approximately the stated proportions: 20% potassium chlorate, 20% managanese oxide, 20% iron oxide, 20% copper oxide, and 20% calcium carbide, so as to transform the carbon monoxide present in the exhaust gases into carbon dioxide, and immediately thereafter treating said gases with an absorbing agent consisting of the following components in approximately the stated proportions: 50% calcium oxide, 20% iron sulphate, and 30% caustic soda.
