HIGH-SPEED CARBONIZER
ENVIRONMENTAL ASSESSMENT NOT NECESSARY AND IMMEDIATE INSTALLATION POSSIBLE
ALL TYPE OF WASTES FROM MUNICIPAL TO LIVESTOCK ARE TREATED UNDER SUPER-SPEED CARBONIZING
With a “water-cooling” type system, gases from the benzene system, waste steam, hazardous gas and sludge are produced. These gases are conducted to the vaporized gas cooler and removed later with the sludge. If a hazardous gas is not removed, it is discharged into the atmosphere as a non-pollutant by passing through indirect heating in the platinum catalytic deodorant device. A cooled material in liquid form is conducted to the Cyclone Dryer, and recycled as dried sludge. Waste steam from the Cyclone Dryer is conducted to the deodorant and hot air generator in which pollutant substances in the steam are broken down through oxidization; at the same time, the steam is converted into a high-temperature, vaporized gas containing high calories, which is re-circulated to the jacket of the carbonizer, and finally emitted into the atmosphere.
When it comes to the “oil-cooling plus water-cooling” type of system, vaporized gases from the benzene system, waste steam, pollutant gas, chlorine gas, and sludge are produced during the operation. In the first place, gases from the benzene system are cooled in the vaporized gas cooler with oil coolant. Then, through the chlorine gas eliminator (with alkaline rinsing), the chlorine, waste steam and hazardous gas are removed. The chlorine is transformed into salt water, while the remaining pollutant gases are treated in the platinum catalytic deodorizer under direct heating, and then emitted harmlessly into the atmosphere. An oil, having been cooled by a vaporized gas cooler, usually contains some water and sludge. In order to separate the oil (for use as supplementary fuel), a triple-stage centrifugal separator is used, separating out oil, sludge, and water. Water from both the chlorine gas eliminator and the centrifugal separator is fed into the cyclone dryer, where a solid saline product is produced, while waste gas is conducted to the deodorant and hot-air generator, in which hazardous gases are broken down into a non-pollutant hot steam gas through an oxidizing process. This non-pollutant hot gas is fed into the inside of the jacket of the carbonizer as a heating medium, and then finally emitted into the atmosphere.

CHARACTERISTICS
1. Treatment of all type of waste materials mixed together.
The gas-cooling type carbonizer can process not only municipal wastes such as raw garbage, paper and plastic but also such materials as car-shredder dust, waste tires, medical waste and paper diapers that normally cause problems in incinerators. Needless to say, even if vinyl chlorides are present, no dioxins will be produce.
2. Wastes in liquid form with more than 98% of water content can be carbonized directly.
The gas-cooling type carbonizer can treat material with a high content of water such as agricultural wastes, wastes of marine products, sludge from factories, liquid wastes, livestock excreta, without any prior drying process. These materials are transformed into a non-pollutant end product -carbon.
3. Immediate installation possible due to non necessity of environmental assessment.
The gas-cooling type carbonizer is able to utilize recycled oil as a supplementary fuel, which is recovered by cooling the waste gas produced during carbonizing. According to a revision of the regulations for waste treatment, this process is not subject to the legal control for incinerators, and not subjecte to annual environmental assessment. Therefore an immediate installation will be possible.
4. Lower costs for installation and operation.
In comparison with a gas-fusion furnace which is considered not to generated dioxin, the gas-cooling type carbonizer, with the same treatment capacity, requires an investment cost of only one third, one fourth of the running costs and 1/10 of maintenance costs respectively.
5. Super compact design makes it possible to save the space of installation, and be more flexible in choice of location.
Compared to the gas-fusion furnace, the required space for installation is only 1/4. In addition, there is no risk of ignition or explosion at all. Therefore you can install the carbonizer anywhere you like.
6. Easy control makes continuous automatic operation it possible.
An operation is carried out just by pushing buttons on the control panel. This is a very simple process, and makes it possible for the machine to be operated under a continuous automatic system.
7. No production of dioxin or harmful oxides.
Because of the non oxygen pyrolysis process, the carbonizer does not emit dioxin,CO2, SOx, or NOx.
