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

Abstract

A rapid heating device for organic solid waste mainly includes an infrared heater, a heating furnace, a pyrolysis furnace and an automatic control unit. The pyrolysis furnace is embedded in the heating furnace, and the outer wall of the pyrolysis furnace is coated with infrared absorbing paint. The infrared heater is located on the outer wall of the heating furnace, and the rapid heating of the pyrolysis furnace is realized through thermal radiation. According to needs, multiple infrared heaters can be set up for rapid heating of the pyrolysis furnace. The inner wall of the pyrolysis furnace is covered with an insulation layer to prevent heat loss in the pyrolysis furnace and maintain the temperature of the material, so as to achieve rapid heating and high-efficiency heat preservation of the material, shorten the heating time of pyrolysis, improve the efficiency of organic solid waste pyrolysis, and effectively reduce dioxins produce.

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...
