Organic waste cracking and fractionating device and method

Abstract

The invention discloses an organic waste cracking and fractionating device and method. The organic waste cracking and fractionating device comprises a feeding device (1), a rotational cracking furnace (2), a gas-solid separator (4), a rectifying tower (5), a built-in condenser (6), a condenser (7), a receiving tank (8) and a combustible gas liquid sealing tank (9). The organic waste cracking and fractionating method comprises the following steps of: feeding organic waste into the rotational cracking furnace (2), recycling gas carbon residue after thermal cracking, separating solids such as charcoal by virtue of a discharging bin, feeding gas of the gas-solid separator (4) into the rectifying tower (5), feeding the gas into the receiving tank (8), and feeding non-condensable into a combustion system. The organic waste cracking and fractionating device and method disclosed by the invention have the advantages that raw materials are not required to be smashed, no fine screening is required, a guarantee that the raw materials are uniformly heated and quickly cracked is realized, noneffective condensation reaction is reduced, the energy consumption is reduced, the raw fuel stock refining process is simplified, and an oil product has the advantages of good colour and lustre and high added value.

Description

technical field [0001] The invention relates to a cracking and fractionating device and method for organic waste. Background technique [0002] At present, the annual output of garbage in large, medium and small cities in my country is nearly 140 million tons, and it is still increasing at a rate of 80% every year. The huge population consumption and the ever-expanding city scale make China one of the countries with the heaviest garbage burden in the world. All kinds of industrial waste and municipal solid waste that are difficult to handle pose a huge threat to people's survival. The same problem is the straw produced by agricultural production, and the burning of straw has affected the serious pollution of the atmosphere. Pollutants emitted by straw burning and wood burning stoves mainly include suspended particles, hydrocarbons, carcinogenic polycyclic organic compounds such as benzopyrene, carbon monoxide, formaldehyde, etc., which can cause respiratory infections, hear...

AI Technical Summary

Problems solved by technology

Therefore, the simple simple landfill and incineration of organic waste generated by urban life and agricultural production can no longer meet the requirements of environmental pollution control, and can easily cause serious secondary pollution, directly threatening the air, soil, groundwater and drinking water safety
