SMOKE-WASHING DEVICE.
Application filed' January 30, 1926.
The present invention relates to a device for remedying the smoke evil.
The principal object of this invention is to provide means whereby the smoke from a boiler or other furnace may be washed or freed from carbons, other solids and ob-- noxious substances, so that only clear, colorless and inoll'ensive gases may be liberated into the atmosphere.
Other objects of the invention will appear from the following detailed description thereof".
In the drawings: I
Figure l is a plan view of the device.
Figure 2 is a sectional view of the reservoir, the operating parts being shown in side elevation.
The numeral 1 indicates an exhaust fan of any desirable construction connected by means of a pipe 2 with the smoke outlet of a furnace 8. The fan 1 is driven by any convenient source of power through a shaft 4, arrangement for variable speed being made by a cone pulley 5. Provision is made for cooling the exhaust fan 1 by means of a water pipe 6 communicating with any suitable source of supply, the end of said pipe being perforated to permit water to drip upon the fan. The fan 1 rests upon a con crete base 7 which forms one wall of a concrete tank or reservoir 8 in which water is maintained approximately to the level of the line I). The exhausttrom the fan 1 is carried by means of a pipe 10 to a centrifugal pump 11. The pump 11 is mounted on a concrete base 12 near the bottom of the reservoir 8 and is entirely submerged in the water in said reservoir. The pump 11 besides receiving the exhaust from the fan 1 also takes in water from the reservoir through an open ended branch pipelS. The
utlet 1% of the pump 11 is connected by means of a pipe 15 with the intake 16 of a second centrifugal pump 17 similar to the pump 11. The pump 17 is mounted on the concrete base 18 on a higher level than the pump 11.. Inside the concrete reservoir 8 is a closed metal tank 18 into which the pump 17 discharges through a pipe 19 and a pipe 20, which extends through the top of the reservoir 18 The metal reservoir 1% connnunicates with the reservoir 8 through screened openings 21 below the water level Serial No. 84,963.
and thus the water is maintained in the reservoir 18 at the same level as in the main reservoir 8. The pipe 20 extends below the water level in the reservoir 1S as will be seen in Figure The reservoir 1S is provided with an outlet 22 just above the water level from which a pipe 23 leads to any suitable exhaust location. The reservoir 18 is further provided. with a drain through which the water may be drained oil and said reservoir cleansed when necessary. The pumps 11 and 17 are driven by means oi pulleys from any suitable source of power and it is desirable that said pumps be driven at a slightly higher rate of speed than the fan 1.
It is thought that the operation of the device will be apparent to those skilled in the art to which the same appertains from the foregoing description. The smoke from the furnace 3 is exhausted by the tan 1 and carried through pumps 11 and 17. In pump 11 it is mixed with water and the operation of the two pumps causes the smoke and fumes to be thoroughly washed and the solids taken up by the water. The pump 17 exhausts into the closed reservoir 16 where the solids are deposited in the water in said reservoir and the gases permitted to be carried oil through the pipe 23.
It will be understood that while I have shown in the construction only two washing or mixing pumps, any suitable number in order to accomplish the result may be eniploy'ed in series as shown. It will also be understood that it may at times be desirable to provide for a continuous flow from the reservoir 18 through the drain 24, such flow being compensated for by means of the inflow from the sprinkler pipe 6.
By means of the device described it will be understood that I have provided a forced draft for a furnace and have also been able to eliminate entirely the necessity for a smoke stuck or chimney.
It will be observed that in the mechanism shown, I have provided a means whereby the smoke and exhaust fumes from a furnace may be thoroughly washed and the solids removed from the gases, the latter being liberated into the air at any desired point and the solids being retained in the water to be carried off by it, thus preventing said solids from being liberated into the atmosphere as is the case where ordinary fines and smoke stacks are provided.
