Vertical multi-directional heating organic solid waste pyrolysis device

Abstract

Vertical multi-directional heating organic solid waste pyrolysis device, a closed pyrolysis space is formed between the outer cylinder, the inner cylinder and the upper and lower end covers; the outer wall of the outer cylinder is spiraled with a spiral coil as an external heating channel, The outer surface of the upper part of the cylinder is provided with a feed inlet connected to the feed device and an outlet connected to the pyrolysis gas export device; the outer circumference of the central cylinder is spiraled with a spiral tube, and the spiral tube is fixed by paddles on the outer side of the central cylinder. Both ends of the spiral tube are connected with the central cylinder, and a spiral plate is arranged inside the central cylinder, thereby forming a spiral channel for heating gas inside the central cylinder, and a flow-limiting orifice is arranged under the spiral plate; the central cylinder is driven by a frequency conversion motor, and the lower sealing cover A slag outlet connected to the slag outlet is provided. The present invention has two heating heat sources, inner and outer, and the inner heat source is divided into a center and an intermediate heat source, so as to ensure the oxygen-free and continuous pyrolysis device for materials. The use of spiral channels greatly increases the heating area and the residence time of heating gas, which can fully release heat and increase production capacity.

Description

technical field [0001] The invention relates to a vertical multidirectional heating organic solid waste pyrolysis device, which belongs to the field of organic matter cracking and is used for pyrolysis, carbonization or drying of organic solid waste. Background technique [0002] Every year, a large amount of organic solid waste needs to be treated in our country. Organic solid waste generally includes waste plastics, rubber, residual oil, oil shale, coal powder, straw, wood chips, etc., especially the waste plastics and waste contained in the growing urban waste. Rubber organic solid waste, the general methods to deal with these organic solid wastes are landfill, incineration, and pyrolysis. [0003] (1) Landfill: Landfill needs to occupy a large amount of land and farmland, and at the same time pollute the groundwater body. Since waste plastics and waste tires are organic solid wastes that are difficult to degrade with polymers, it takes 500-1000 years to degrade naturally...
