Organic solid waste rapid heating device and heating method

Abstract

An organic solid waste rapid heating device mainly comprises infrared heaters, a heating furnace, a pyrolyzing furnace and an automatic control unit. The pyrolyzing furnace is embedded in the heating furnace, the outer wall of the pyrolyzing furnace is coated with an infrared wave-absorbing coating, the infrared heater is located on the outer side wall of the heating furnace, and rapid heating of the pyrolyzing furnace is achieved through heat radiation. According to requirements, the plurality of infrared heaters can be arranged and are used for quickly heating the pyrolyzing furnace. The inner wall of the pyrolyzing furnace is covered with a heat preservation layer, heat loss in the pyrolyzing furnace is prevented, and the material temperature is maintained, so that rapid heating and efficient heat preservation of materials are achieved, the pyrolysis heating time is shortened, the organic solid waste pyrolysis efficiency is improved, and dioxin is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of energy conversion and resource recovery of organic solid waste, and in particular relates to a device for rapid heating and high-efficiency heat preservation of organic solid waste. [0002] The invention also relates to a method for rapid heating using the above-mentioned device. Background technique [0003] my country has a large output of organic solid waste, with an annual output of 5 billion tons, but the reduction and recycling rate is low, seriously affecting the urban living environment. Pyrolysis technology can realize the reduction and resource utilization of organic solid waste, and it can convert biomass energy into gas, bio-oil, bio-char and other resource-based products. With the construction of waste-free cities, organic solid waste pyrolysis technology has attracted more and more attention. At present, the research on pyrolysis technology mainly focuses on the optimization of the pyroly...

AI Technical Summary

Problems solved by technology

At present, the research on pyrolysis technology mainly focuses on the optimization of the pyrolysis system and the discharge of tail gas up to the standard. The existing organic solid waste pyrolysis technology and equipment have disadvantages such as long heating time, long start-up time of pyrolysis equipment, and low thermal energy conversion efficiency. , and the slow heating rate leads to the generation of dioxins during the pyrolysis process, which increases the cost of back-end disposal and greatly limits the promotion of organic solid waste pyrolysis technology
