Definitions
- the present invention in general relates to a device for use with a carbonizer system; and inparticular to a rotating drum device for use with a carbonizer system for transforming waste into useful co-products and a process of use thereof.
- Waste from a hazard to an asset is a high global priority.
- the benefits of transforming waste materials are well known and include, but are not limited to, reduction in the stream of landfill-bound waste, and reduction in the amount of harmful chemicals and other pollutants that would otherwise be released into the environment.
- Waste -related chemicals and other waste-related pollutants not only pose a risk to the environment, but can also pose a significant risk to human health.
- Most common household materials, including paper, metals and glass can be transformed and recycled for re-use by industry, thus avoiding the landfill-bound waste stream.
- transforming and recycling less common non-household and industrial waste materials, such as medical waste, into useful co-products presents more complex challenges.
- Infectious and/or contaminated waste includes items such as: cultures and stocks of microorganisms and biologicals; blood and blood products; pathological wastes; syringe needles; animal carcasses, body parts, bedding and related wastes; isolation wastes; any residue resulting from a spill cleanup; and any waste mixed with or contaminated by infectious and/or contaminated waste.
- Traditional sterilization methods include: incineration; steam treatment or autoclaving; and infectious and/or contaminated liquid waste may be disposed of in approved sanitary sewers.
- Pyrolysis is a general term used to describe the thermochemical decomposition of organic material at elevated temperatures without the participation of oxygen. Pyrolysis differs from other high-temperature processes like combustion and hydrolysis in that it usually does not involve oxidative reactions and is often characterized by irreversible simultaneous change of chemical composition and physical phase.
- Pyrolysis is a case of thermolysis, is most commonly used for organic materials, and is one of the processes involved in charring.
- Charring is a chemical process of incomplete combustion of certain solids when subjected to high heat. The resulting residue matter is called char.
- charring By the action of heat, charring reductively removes hydrogen and oxygen from the solid, so that the remaining char is composed primarily of carbon in a zero oxidation state.
- Polymers such as thermoplastics and thermoset, as well as most solid organic compounds like wood and biological tissue, exhibit charring behavior when subjected to a pyrolysis process, which starts at 200- 300 °C (390-570 °F) and goes above 1000°C or 1800°F, and occurs for example, in fires where solid fuels are burning.
- pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content, commonly called char.
- Extreme pyrolysis which leaves mostly carbon as the residue, is called carbonization.
- Efficient industrial scale pyrolysis has proven to be difficult to perform due to difficulty in adjusting reactor conditions to feedstock variations in order to achieve a desired degree of carbonization.
- waste processing reactor or heat source, which are designed to operate at relatively high temperature ranges such as 200-980° C (400 to 1800 °F) and allow for continuous or batch processing.
- An essential element of chemical reactors used in waste processing is for a reactor to enhance mixing and reduce variable reactive conditions associated with spatial variation in the waste material being processed. It should be appreciated that these features should be optimized in order to create conditions which maximize heat diffusion, through material convection, in order to reduce the amount of processing time. While those variables are readily controlled in pilot scale systems, precise control of the aforementioned variables at industrial scale processing has proved difficult.
- Various reactor feed and waste treatment devices are currently available in the industry. Many devices operate to produce a steady flow of material to a reactor, with varying methods of compaction. However, these conventional devices are not satisfactory in that they are not versatile enough to accommodate, process, and adequately compress heterogeneous waste streams comprising a variety of constituent waste materials.
- a waste transforming rotating drum device for use with a carbonizer system which can accommodate various types of waste materials to be processed and provide for the continuous flow-through of heterogeneous waste streams with varying compression ratios.
- a process of using a waste transforming rotating drum device for use with a carbonizer system that efficiently transforms non-household, medical, and industrial waste into useful co-products in an economically sustainable manner thereby promoting the overall economic value of the process of transforming and recycling waste from a hazard into an asset, while simultaneously reducing the negative impact such waste would otherwise have on human health and the environment.

- a plurality of internal angled vanes are disposed along an inner wall of the drum and are oriented so that waste material inside the drum is moved progressively through the drum from an inlet within a first end of the drum towards a discharge outlet within a second end of the drum.

- the inventive rotating drum device is rotatable about a horizontal axis and has a plurality of external threads disposed along a circumference of the outer wall of the drum that are adapted to engage the at least one external rotating drum drive motor in order to drive rotation of the drum.
- a process of feeding waste material into and progressively through the inventive rotating drum device includes the steps of introducing waste material into the center feed line in fluid communication with the augered feed line in fluid communication with the inlet within the first end of the drum and the inlet housing aperture within the inlet housing adapted to receive the first end of the drum; moving waste material through the center feed line and the augered feed line into the drum; progressing waste material through the drum from the first end towards the second end with the plurality of internal angled vanes disposed along the circumference of the inner wall of the drum; indirectly heating the waste material within the drum with the heating jacket encapsulating the circumference of the outer wall of the drum; rotating the drum about a horizontal axis with the plurality of external threads disposed along the circumference of the outer wall that engage the at least one external drum drive motor; controlling the amount of waste material moving through the drum by controlling at least one of: the rate of rotation of the drum, the speed of the augered feed line, the volume of waste dispersed into the drum, the volume of waste discharged
