Abstract
The invention discloses a rotating packed bed pyrolysis furnace and a domestic refuse treatment system with the same. The rotating packed bed pyrolysis furnace comprises an annular furnace chamber, a feed distribution furnace disk, a transmission device and an electrical heating device, wherein the annular furnace chamber is a space composed of an inner circumferential wall, an outer circumferential wall, a top wall and a bottom wall, and is divided into a feeding area, a drying area, a pyrolysis area and a discharge area; the feeding area is provided with a feed inlet; the pyrolysis area is provided with a high-temperature oil and gas outlet; the discharge area is provided with a slag discharge outlet; the feed distribution furnace disk can horizontally rotate and is located at the bottom part of the annular furnace chamber; the transmission device is arranged below the feed distribution furnace disk and connected with the feed distribution furnace disk to drive the feed distribution furnace disk to horizontally rotate; and the electrical heating device is arranged above the feed distribution furnace disk. The rotating packed bed pyrolysis furnace provided by the invention has high heating efficiency, simple structure and low energy consumption, can realize effective quantity-reducing treatment of domestic wastes, is friendly to the environment and is especially applicable to large-scale promotion.
Description
technical field [0001] The invention relates to the field of energy and chemical industry, in particular, the invention relates to a rotary bed pyrolysis furnace and a domestic waste treatment system provided with the rotary bed pyrolysis furnace. Background technique [0002] With the rapid development of the economy, the continuous growth of the population and the improvement of people's living standards, especially the recent rapid growth of the express delivery business, the generation of domestic waste in China has also increased sharply. At present, the annual generation of domestic waste in China is about 150 million tons. , and it is still growing at a rate of about 5% every year, which has caused a great burden on the environment. Two-thirds of the large cities in the country are facing the dilemma of "garbage siege". [0003] At present, landfill and composting methods commonly used in waste disposal have fallen into the dilemma of occupying a large amount of land ...
