vices of this type in which 'saidsuction is inv duced'by the injection of steam into the pas The main objects of my invention are, to economically utilize the steam employed in inducing the suction, by causing it to interchange its heat with the feed-water to the steam generator; also, to use said steam and the accompanyin disposition to thebest advantage in the stack of'the generator, thereby, not only ,ewettiuq 'ri'd of the dust, but also -1ncreasing the draft through the generator, and the consequentthorough combustion of the fuel; and,
finally, to provide for the automatic regula-.
tion of the feed-water supplied to the generator.
consists in the novel construction and arrangement of the apparatuswhich I shall now fully describe, by reference to the accompanying drawings' in which? 3 Figure 1 is an elevation of myapparatus, partly in section Fig. 2 is a cross section on the line 00-48 of Fig. 1. M
1 is a pipe which must be supposed to lead from any suitable sounce of dust-collection, and to be connected with any of the ordinary or well known suction nozzles, renovators, or like devices, which are moved over the surface to be cleaned. An extension 2 of this pipe leads 0 and opens into the base of characteryand 6 is its stack.
a heat-interchanger 3 of some suitable character, as, for example, one which comprises an external shell and inclpsed pipe-System 1, Fi 2. Around \this-pipe-system 4, the dust la en-air from pipe 1, and the steam which induces the suction, flow.
5 is a steam-generator of any suitable steam-space of the generator leads'a pipe 7, -the end of whichhas an injector 8 which is dust-laden air, by their With these objects in view, my invention From the let into the pipe 2 in such position as to induce a current of dust-laden air to How through pipe 1, and to force said air forwardly into and through the heat inter? changer. changer 3 leads a pipe 9 to the stack 6 of the 1 generator.
10 is a feed-water pump. A pipe 11 leads from this pump to the top of, the heat-interchanger, where it communicates with its p pe-system 4. From'this pipe-system a plpe 12 leads to and supplies water to the generator.
2.3,is'a pipe connection from the steamprpefj for operating the feed-Water pump.
14' is a cylinder containing a piston 15 controlled by a spring 16 adaptedto yield to a predetermined pressure. With the rod 17 of the piston a lever 18 is suitably connected,
'sai'd lever operating a valve 19 in the pipe connection 13 .which'supplies steam to oper-- ate the pump'.
20 is a pipe leading from the Water connection 12 of the generator to the cylinder 14 under its piston 15. In thewater conand the pipe 20, is a check valve 21. The operatlon of the apparatus is as follows .*Ste am from the generator, passing from the injector 8, induces suction in the dust-pipe 1 and its extension 2, and forces the dust-laden -air up into and through the heat-interchanger; and the air and steam thence pass to the stack 6, by which means thedustis'disposed of, and an increased draftacreated in the generator. 'The steam in passing through the heat-interchanger gives up its heat, or a portion thereof, to raise the temperature of the water flowing throu h the pipe-system of the interchanger, Where y said Water is economically supplied 'to the generator with a preliminary heat.
The steam pressure in the generator, acting on the water, will cause thel'atter, through the pipe 20, to lift the spring-controlled piston 15, when said pressure is in excess of that for, which it is set, and thereby, through the lever 18 and steam valve 19, automatic ally regulate the supply of steam to operate the pump, thus regulatingthe supply of water to the needs of the generator, whereby the steam is kept constant to supply the injector and effect a constant suction for the work to be accomplished through the dust-pipe 1.
From the top of the heat-interw Having thus described my invention, what necti'on 12,-between the heat-interchanger its contents; a steam generator; a steam-pipe interchanger in such manner as to induce a I claim as new and desire to secure by Letters Patent is 1. A dust-removing apparatus comprising a pipe leading from a source of dust-collection; a'heat-mterchang'er comprising a tubular chamber to which said pipe delivers therefrom having its outer end provided with an injector disposed Within thepommunicationbetween the dust-pipe and the heatsuction in said dust-pipe and to force its contents through said heat-interchanger; an outlet for the dust and steam from said heatinterchanger; a' source of feed-water for the generator; a water conduit within the tubular chamber a water-pipe connection between said feed-water source and the water conduit; and a pipe-connection for the water from said conduit to the steam generator.
2. A'dust-removing apparatus comprising a pipe leading from a source of dust-collec tion; a heat-interchanger to which said pipe delivers its,contents; comprising a closed chamber; a steam generator; a steam pipe therefrom having its outer. end provided with an injector disposed within the communication between the dust-pipe and the h'eat-interchanger in such manner as to induce a suction in said dust-pipe and to force its contents through said heat-interchanger; an outlet pipe for the dust and steam from said heat-interchanger communicating with the stack of the steam generator; a source of feed-Water for the generator; a pipe within the 3 heat interchanger chamber in the path of and adapted to be traversed by the material forced through said chamber, a Waterpipe connection between said feed-Water source and the said pipe; and a pipe-connection for the water from-said pipe to the steam generator. 4
3. A. dust removing apparatus comprising a steam generator having a suitable stack projed t-ing therefrom, a heat interehang'er comprising a closed tubular chamber, a dust receiving having connection with the heat interchanger, a steam plpe having a connection "at one endwith the generator and terminating-at its opposite end in a jet nozzle disposed within the connection between the dust receiving pipe and tubular chamber, an outlet for the contents of the chamber connecting directly with the said generator stack, a water pipe system mounted within the closed chamber and constructed and arranged to be enveloped by the pass.- ing contents of the chamber, an inlet for the pipe system, and an outlet therefor communicating directly with said generator.
4-. A dust removing apparatus comprising a steam generator, a heat interchanger spaced therefrom and comprising a hollow chamber closed throughout, a water pipe Within the said chamber and closed throughout, a water supply connecting with one end of said pipe, an outlet connection leading from the other end of said pipe to the generator', a dust inlet pipe, a steam pipe leading from the generator connecting with the dust inlet pipe at its point of connection with said chamber, and governing mechanism for regulating said water supply including pumping instrumentalities, a steam connection comprising a pipe connected with said first mentioned steam pipe intermediate its ends-and with the pump, and a valve controlled device for said steam connection including a pipe connected with the outlet connection of the water pipe at a point between its connection with the generator and the water pipe.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
