Device, method, and control system for waste to energy generation and other output products
Aspects of the present disclosure include devices, systems, methods, and control systems for processing a feedstock into an output product having variable preselected characteristics. Various system components may include: 1) a feeder configured to convey the feedstock; 2) a mechanical pulverizer configured to pulverize the feedstock received by the feeder into pulverized feedstock; and 3) an air conveyor for conveying an air flow into the mechanical pulverizer and to draw the air flow from the mechanical pulverizer to a fines separator. The pulverized feedstock includes one or more of heavy fines, particulates, moisture, or combinations thereof. The air flow from the mechanical pulverizer includes at least a portion of the pulverized feedstock, wherein the portion of the pulverized feedstock is conveyed by the air flow.
1. A system for processing a feedstock into an output product having variable preselected characteristics, the system comprising:
a feeder configured to convey the feedstock;
a mechanical pulverizer configured to pulverize the feedstock received by the feeder into pulverized feedstock, wherein the pulverized feedstock includes one or more of heavy fines, particulates, moisture, or combinations thereof, wherein the feedstock entering the mechanical pulverizer has a moisture content of 20 to 60 wt. %, and wherein the feeder is configured to mechanically convey the feedstock into the mechanical pulverizer; and
an air conveyor for conveying an air flow into the mechanical pulverizer and to draw the air flow from the mechanical pulverizer to a fines separator, wherein the air flow from the mechanical pulverizer includes at least a portion of the pulverized feedstock, wherein the portion of the pulverized feedstock is conveyed by the air flow at temperatures between −20° F. to 100° F.
2. The system of claim 1 , wherein the fines separator is configured to separate the heavy fines from the particulates based on one or more of weight, density, and particle size.
3. The system of claim 2 , wherein the heavy fines are collected after passing through the fines separator.
4. The system of claim 1 , further comprising one or more screens that screen the air flow prior to the air flow being conveyed to the fines separator.
5. The system of claim 1 , wherein the heavy fines comprise one or more of conglomerate, fluff, and combinations thereof.
6. The system of claim 1 , wherein the particulates comprise materials not removed from the air flow by the fines separator.
7. The system of claim 1 , wherein a moisture content of the pulverized feedstock in the air flow from the mechanical pulverizer is at most 35% by weight.
8. The system of claim 1 , wherein a velocity of the air flow is between about 1000-24,000 feet/minute (ft/min).
9. The system of claim 1 , further comprising a shredder to reduce initial component size in the feedstock conveyed by the feeder into a selected feedstock subcomponent size prior to delivery to the mechanical pulverizer.
10. The system of claim 1 , further comprising a material analyzer to analyze characteristics of the feedstock conveyed by the feeder, pulverized feedstock, or reclaimed water.
11. The system of claim 1 , wherein the mechanical pulverizer comprises a ringmill, a horizontal hammermill, or a vertical shaft impactor (VSI).
12. The system of claim 1 , wherein at least a portion of the particulates are collected by a fines collector.
13. The system of claim 12 , wherein the fines collector comprises a bag-house.
14. The system of claim 12 , further comprising a filtration component for applying filtration to the air flow from the fines collector.
15. The system of claim 1 , wherein the fines separator comprises a cyclone.
16. The system of claim 1 , further comprising:
an air quality analyzer.
17. The system of claim 1 , wherein the air flow contains preconditioned air.
18. The system of claim 1 wherein the air flow is conveyed into the mechanical pulverizer via an opening in the mechanical pulverizer.
19. The system of claim 1 , wherein the variable preselected characteristics include one or more of moisture and calorific content.
