DEODORIZING APPARATUS.

Application filed July 28, 1920. Serial No. 399,589.

certain new and useful Improvements in Deodorizing Apparatus, of which the fol-- lowingis a clear, full, and exact description. I

My invention re-iates to a method for deodorizing gases which result from treatmentof waste organic substances, and more particularly the gases resulting from the treatment of garbage, tankage and the like, and an object of my invention is to provide a simple and inexpensive method by which these gases are ompletely deodorized.

the past in. efi'ecting deodorization of such gases, and apparatuses expensive to con-' struct and operate have been roposed' but these have not proved success ul in operation.

An important feature of my invention consists in using SO as a'deodorizer, and

suclrSO may be produced in any desired manner, as by burning sulphur and mixing the gas generated with the gases which are to be deodorized, these ases being under pressure or otherwise, and preferably steam is mixed with the S0 gas. While my proc essinay be performed in a great variety of ways and by the use of different forms of apparatus, for the purpose of illustrating a ractical embodiment of my invention I ave shown one form of apparatus by which it ma be successfully practiced.

Re erring to the drawing. 1 indicates a receptacle which may be of a variety of shapes suited to the particular purpose for which it is to be used. In this-tank the waste organic substances may be treated by what is known as dry cooking, or the substances may be treated by bo-iling o-r. steaming. 2 indicates a stack leading from the receptacle 1, and through which the waste gases pass. I prefer to treat these gases,

uring their passage, through the stack, although they may be treated while in the tank, or they might be conducted to a separate -'chamber and theretreated, and for this purpose I provide'a sulphur burner indicated diagrammatically at 3. This sulphur burner maybe of any desired construction-such, for instance, as'that shown in my application Ser. No. 302,243, A gas con'veyer 4 leads from this sulphur burner and enters the stack 2 through a suitable opening therethrough. The conveyor 4 has a restricted'nozzle at 5, which projects into the stack and terminates adjacent a restricted portion 6 formed in the stack. Suitable means are provided whereby the S0 gas. generated in the sulphur burner is delivered at the nozzle 5, where said gas mixes with the waste gases in the stack 2 and combines with them in such manner as to efiect complete deodorization of the same. Stack 2 may be bent downwardly, as shown; and at some suitable point therein, as at 7, water may be sprayed into the stack 2 so as to I condense the gases, from which point 7 the Great difiiculty has been experienced in condensed gases may be allowed to pass through a waste tank 8 which is in communication with a sewer. Such gases as are not condensable may pass into the atmosphere, but these as well as the gases which are condensable are completely deodorized by the treatment to which they have been subjected.

The SO gas ma be delivered under pressure to the nozziie 5, and to do'this I have shown a steam pipe 10 leading from a steam generator 11, the end of the pipe passing into the conveyor 4 through a nozzle 12, the steam acting to aspirate the S0 gas passing up the conveyor 4.. Other means of delivering the S0 may of course be employed.

It is to be understood that the manner of a procedure and the form of device for carrylug out my improved process may be varied to suit different conditions without in any manner departing from the spirit of my invention;

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. The method of'deodorizing gases resulting from the treatment of waste organic substances, which consists in introducing S0 and steam into the conduit along which said gases pass.

2. The method of deodorizing gases resulting from the treatment of waste organic substances, 7 which consists in introducing SO, and steam into the conduit alongwhich said gases pass and subsequently cooling the mixture.

3. The method of deodorizing gases resulting from the treatment of waste organic subtances, which consists in introducing hot S0 and steam'into the conduitalong, which said gases pass. 1 v

4. The method of deodorizing gases resulting from thetreatment of waste organic substances, which consists in introducing hot S0 and steam into the conduit along which said gases pass and subsequently cooling the mixture 5.
