Application filed December 29, 1924. Serial No. 758,535.

This invention relates to the disposal of gases and vapors generated during the heating or boiling of oils,'gums, resins and the like and is more particularly directed to the disposal of such gases and vapors which accompany the making of varnish. In the manufacture of varnish, the constituents thereof are placed in kettles and are subjected to arelatively high degree of heat during which operation heavy vapors and gases which are obnoxious .to the workmen and public in general and are dangerous because of their explosive qualities.

\5 In most of the larger cities, ordinances prevail against the discharging of the fumes resulting from varnish making into the at mosphere and as a result numerous expedients have been resorted to to ameliorate l0 this difficulty. These expedients, however, have not proven a practical solution of the problem either because of the expedients in- I volved in their installation and operation or because of their complex, inconvenient and an unhandy nature. The most common of such expedients consists in apparatus forchemically scrubbing the fumes and otherwise .chemicallyacting on them in an attempt to divest them of their injurious or obnoxious characterls'tlcs after which the remaining gases are exhausted into the atmosphere usually through high stacks.

As hereinbefore stated, however, the prior methods of treating fumes of the character described have not met with favor in the trade and do not fulfill the required results.

As a result municipalities in general have practically banished varnish factories from said limits and they are forced to erect 40 plants beyond such city limits in the country or suburbs where adequate transportation facilities are lacking with resulting high cost ofmanufacture. I

The object of the present invention is to provide for the efficient and economical disposal of fumes of the character described in such manner as to absolutely destroy their obnoxious and dangerous characteristics, and in accordance with the invention, the fumes are taken from the boiling kettle and trans-- ported to a furnace Where they are burned and completely destroyed.

The fumes resulting from the preparation of varnish are very heavy and after rising to the op of the kettle flow over the upper edge there arises from the kettle.

' injector which serves rectly passed into the furnace,

thereof and descend to the region of the floor, stratifying in a dense mass above the fire used to heat the kettle and rendering the vicinity not only dangerous to workmen,but also obnoxious to any one in such vicinity.

Prior attempts have been made to draw the fumes direct from the kettle by means of .mechanically operated fans and to discharge them through pipes eitherto the stack-or into chemical treatment apparatus, but practical experience has shown that these fumes contain such alarge amount of gummy constituents that they rapidly clog such fans or blowers and necessitate almost continuous maintenance in order to keep the fans and outlet conduits clean and unobstructed. Thus, in practically carrying out the invention, I provide the kettle with a suitable hood and this hood is in turn provided with .an outlet duct arranged as near as possible to dge of the kettle so that the the upper e fumes will not have to be raised any higher than necessary to flow into the outlet, whence they are conveyed preferably in a downward direction to a suitable treating chamber. The down direction is practically important because of the weight of the fumes and their tende'ncy'to descend. In practice, the fumes may be feddirectly to the furnace, ,but I preferably accelerate their flow through the outlet pipe by means of a steam or hot water 7 to maintain the. pipe hot and thereby eliminate deposits of y material on the interior thereof. A lower may be also positioned within the pi e, but if such is the case, the blower is pre erably a steam or hot water operated machine, so that it will in itself embody sufficient heat to maintain the products on which it operates in a liquid condition and preclude sticking or adhering. of the products to the blower mechanism.

When I employ steam or products passing admixed therewith and should not be diso that in such instance, I pass the products and water or water of condensation through a suitable hot water, the

treating chamber to. remove the excess water after which 'said products maybe passed 'directly to the furnace. By this method and apparatus, the products are delivered in a composite state to the furnace wherethey are burned and totally destroyed.

Features of the invention, other than those through the pipe become specified, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawings.

The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as definin the limits of. the invention.

The drawing shows a system or apparatus embodying the present invention in a more or less diagrammatic manner.

Referring to the drawing, 1 designates a treating kettle of which in practice there may be several. Each kettle is provided witlr.

the usual rollers 2 to permit it to be moved into and out-of cooperative relation with the fire. Above the kettle is mounted a hood 3, which, in practice, is preferably made in two parts 3 and 3 The art 3 may conveniently be supported on t e masonry adjacent the fire so as to be in stationary position while the part 3' is pivoted to the part 3", as shown at 4. The two sections of the hood are preferably made of semispherical contour and inasmuch as the section 3 is pivoted to the other section as described, said former section can be ivoted back over the latter to permit of t e movement of the kettle into and out of cooperative relation with the hood or to inspect the interior of the kettle, although during treatment thev section 3* is in the position shown wherein it will close and seal the top of the kettle. The hood sections are made to have a good fit with the top of the kettle, so as to preclude leakage of vapors at this point. Extending'to one side of the hood an preferably as close to the lower edge as possible is an outlet duct or pipe 5 which leads in a enerally downward direction awa from t e hood. This pipe is provided wit anumber of branch. ipes 6 leading from additional kettles so' t at the fumes from the umes to the furnace. To e ect t is operaseveral kettles may be fed into the common tion one or more" blowers 7 are preferably employed and these blowers are preferably steam or hot water operated so as to mamtain the fumes in a heated condition and preclude the depositing of gummy constituents either upon the interior of a p pe or upon l the mechanical parts of the blower.

In the preferred form of the invention, however, the flow of fumes is preferably acceleratedb meansof a steam or hot water injector, w ichmay be used with or to. the

- trol exclusion of the blower or blowers 7. The

pressure and in the direction of flow of fumes to accelerate the flow and at the same time become admixed with the fumes, so as the dilute them sufliciently to at least partially divest them of their sticky characteristics, so that they will not be so apt to stick to the pipe 5.

Another important function inherent in the use of hot water or steam is that the heat of these fluids will maintain the fumes at a sufficiently high temperature to further preclude sticking and which would result in clogging of the apparatus. It will be noted moreover that a considerable portion of the pipe 8 extends intothe pipe 5 and such part of the pipe 8 as is interior of the discharge pipe may be in the form of a heating coil if desired. One or more baffles 10 are shown in the pipe '5 to preclude all possibility of retrograde movement of the gases.

hen steam or hot water are employed in carrying out the present invention, the fumes are first passed through an intermediate treating chamber before being conveyed to the furnace and in the drawing this treating chamber is designated by the reference character 11. The gases are fed into the top of the chamber and out of one side thereof through a pipe .5 to the furnace designated in the drawing by the reference character 12. The chamber 11 preferably contains charcoal 13 or some other suitable filtering medium,

- so that during the passa e of the fumes through the chamber 11, t e water or conden'sate will drop out while the volatile vapors or fixed gases will pass across the a used as boiler feed water or may befed and suitable preheated to be used again. .The gases and vapors passing through the pipe 5 may be accelerated by a blower if desired and the blower is preferably used so that the gases will'be rapidly discharged in to the firewithin the furnace. 7

It will-of course be understood that steam for operating the injector is subject to cony a. valve 15 and in like mannerzthe steam for operating the blower is controlled by a valve 16. These valves are preferably so positioned that they may be conveniently and manually operated.

As aprotection against hazards of fire within thekettle, I may, though it is not essential, provide within the hood a perfo- 'having a control valve 19 of fire within the kettle, can be opened to produce a steam blanket within the kettle.

The method and apparatus of this inven-' tion will expeditiously and efliciently remove the fumes from the kettle and feed them to a furnace-where they are totally destroyed so that they arerendered no longer obnoxious or dangerous. The feeding of aqueous vapor into a delivery pipe either in the form;

of steam or waterproduces a pronounced scrubbing action on the fumes and aside from keepin the fumes warm will absolutely preclu e any possibility of a fire starting within the conduit. I have shown in the drawings the pipe 5 for conveying the products from thetreatin chamber to the furnace as leading through the wall of the furnace and through the bridge wall into the firebox, so that during the passage of the gases through the wall of the furnace, they. will ,be further heated and rendered more combustible.

I preferably in practice utilize the heat of the furnace to preheat the gases either in this manner or in an other suitable and convenient manner althou h I may if desired preheat in any desired way or with any suitable means. I may also provide within the treating chamber a heating coil buried in the charcoal. or otherwlse for heating 'the charcoal to a suflicient temperature to volatilize or vaporize the inflammable constituents which may be trapped by the charcoal to such'degree that they will be carried along with the gases into the furnace and burned therein.

The foregoing detailed description sets forth the inventlon in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claims.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent iszi 1.
