Abstract
Abstract Apparatus for totally reducing refuse, such as paper, cardboard, plastics, tin cans and glass, into a granular state of such fine grit that it can then be explosively ignited and reduced further to a smokey remain. This smokey remain is then condensed by a chemical wash and directed to a liquid tank, from which the liquid is flushed away into the sewage system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
183 words
Apparatus for pulverizing and incinerating waste products comprising: a. a refuse receptacle having a rotary pulverizing device positioned at one end thereof and means for rotating said device, b. means for feeding the refuse into contact with said rotary pulverizing device under pressure for pulverizing such refuse, c. an incinerator chamber having an inlet communicating with said refuse receptacle generally below said rotary pulverizing device and an outlet adjacent the opposite end thereof, d. a burner mounted adjacent said incinerator chamber below said inlet and outlet for projecting a high temperature jet flame into said chamber for reducing the refuse to smoke, said chamber being formed with means for diverting a substantial portion of said refuse and said jet flame downwardly and around said incinerator chamber and upwardly through said projected jet flame and the incoming refuse thereby to effect substantially complete incineration of such refuse, e. liquefying means communicating with said incinerator chamber for receiving smoke from said incinerator and condensing said smoke to a liquid form, and f. means for receiving and diluting said liquid prior to removal from said apparatus.
Claim 2
Dependent Claim
183 words
Apparatus for pulverizing and incinerating waste products comprising: a. a refuse receptacle having a rotary pulverizing device positioned at one end thereof and means for rotating said device, b. means for feeding the refuse into contact with said rotary pulverizing device under pressure for pulverizing such refuse, c. an incinerator chamber having an inlet communicating with said refuse receptacle generally below said rotary pulverizing device and an outlet adjacent the opposite end thereof, d. a burner mounted adjacent said incinerator chamber below said inlet and outlet for projecting a high temperature jet flame into said chamber for reducing the refuse to smoke, said chamber being formed with means for diverting a substantial portion of said refuse and said jet flame downwardly and around said incinerator chamber and upwardly through said projected jet flame and the incoming refuse thereby to effect substantially complete incineration of such refuse, e. liquefying means communicating with said incinerator chamber for receiving smoke from said incinerator and condensing said smoke to a liquid form, and f. means for receiving and diluting said liquid prior to removal from said apparatus.
Claim 3
Dependent Claim
73 words
The apparatus of claim 1 in which said means for feeding the refuse under pressure to said pulverizing device consists of a ram having motor driven feed screws and having limit switches in the path of movement of said ram for controlling the movements thereof, said ram travelling from a retracted position at one side of said refuse receptacle to an advanced position closely adjacent said rotary pulverizing device for pulverizing said refuse.
Claim 4
Dependent Claim
56 words
The apparatus of claim 2 in which the pulverizing device is a motor driven rotary disc having a hard tool steel toothed face exposed to the refuse in said receptacle, and said ram is provided with a toothed face adapted to confront the teeth of said pulverizing disc when said ram is in its advanced position.
Claim 5
Dependent Claim
41 words
The apparatus of claim 3 in which the said pulverizing disc and said feed screws for said ram are driven by individual motors separately controlled thereby permitting said disc to be rotated while said ram is moved to a retracted position.
Claim 6
Dependent Claim
34 words
The apparatus of claim 1 wherein said means for receiving and diluting said liquid comprises a tank, and means for controlling the discharge of said diluent from said tank to an adjacent sewer drain.
Claim 7
Dependent Claim
50 words
The apparatus of claim 1 wherein said liquefying means comprises jet washing means positioned within the discharge pipe for the smoke from said incinerator chamber, said jet washing means condensing said smoke to a liquid product, and pipe means for returning said liquid product to said receiving and diluting means.
Claim 8
Dependent Claim
31 words
The apparatus of claim 6 wherein said receiving and diluting means comprises a tank into which the liquid products are directed for diluting the same prior to discharge from the apparatus.
Claim 9
Dependent Claim
77 words
The apparatus of claim 6 further including means for collecting said smoke particles for maximum exposure of said particles to said liquid wash comprising means in said discharge pipe for negatively charging said particles, and a plurality of positively charged plates in said discharge pipe above said negative charging means and located adjacent said jet washing mEans for collecting said charged particles, said jet washing means impinging on the surfaces of said plates thereby liquefying said particles.
Claim 10
Dependent Claim
25 words
The apparatus of claim 8 further including vent pipe means upstream of said liquefying means for discharging from said apparatus the non-liquefied products of combustion.
Claim 11
Dependent Claim
30 words
The apparatus of claim 9 further including conical soot traps and atomizer spray rings in said vent pipe means for further purifying the smoke prior to discharge from said apparatus.
Claim 12
Dependent Claim
48 words
The apparatus of claim 6 wherein said diluting means comprises a tank, and further including means for recirculating the washing liquid comprising pump means having an impeller submerged below the liquid level in said dilution tank and communicating with said jet washing means for supplying washing liquid thereto.
