A recycling method for plastic waste includes the steps of: (a) placing the plastic waste into a reactor; (b) heating the plastic waste in the reactor through a pyrolysis recovery process to generate flammable gas; (c) transferring flammable gas through a condensing unit to convert the flammable gas into liquid phase products; and (d) filtering the remaining out clean gas from the flammable gas by a filtration unit. A recycling system for plastic waste includes a reactor to decompose the plastic waste to create usable fuel products; a condensing unit operatively connected with the reactor; and a filtration unit operatively connected with said condensing unit to filter the usable fuel products.

A material heating device comprises a rotary kiln, a plurality of heat exchange tubes, a hot air hood, a high-temperature gas input mechanism, an exhaust-gas collecting chamber, and an exhaust-gas output pipeline. The rotary kiln is provided with a material feed end and a material discharge end. The heat exchange tubes are in the rotary kiln. The hot air hood is outside the rotary kiln. The air inlet ends of the heat exchange tubes communicate with the hot air hood, and the air outlet ends of the heat exchange tubes communicate with the exhaust-gas collecting chamber. The exhaust-gas collecting chamber communicates with the exhaust-gas output pipeline. The hot air hood communicates with the high-temperature gas input mechanism, and the cavity between the heat exchange tubes and the heat insulation layer of the rotary kiln is a material channel. The heat exchange tubes are directly in contact with the material.

A straight fin for a device for recovering the waste heat of raw coke oven gas in the ascension pipe of the coke oven includes the straight fin body and a group of V-shaped notches disposed on the straight fin body. The depth h of the V-shaped notches is less than the width H of the straight fin body. The distances between the adjacent V-shaped notches increase from bottom to top in the longitudinal direction of the straight fin body. The present invention further provides a heat recovering device and a power generation device both including the straight fins. Moreover, the width, the angle, and the distances in the longitudinal direction of the V-shaped notches at the top of the straight fin are determined according to the temperature field distribution during use of the device.
