Treatment device and treatment method for high-calorific-value carbon-containing solid waste

Abstract

The invention discloses a treatment device for high-calorific-value carbon-containing solid waste. The treatment device is characterized by comprising a crusher, a pulping machine, a pyrolyzing furnace, a cooling and drying device and a gas storage tank which are connected in sequence. The pyrolyzing furnace is of a structure with the diameter of the middle larger than the diameters of the upper end and the lower end, a spraying device is arranged in the middle in the pyrolyzing furnace, and a plasma torch and a filtering device are further arranged in the pyrolyzing furnace. A slag pool is arranged below a slag outlet of the pyrolyzing furnace. The treatment method suitable for the device comprises the following steps of: (1) feeding the carbon-containing solid waste into the crusher forcrushing treatment; (2) feeding the crushed raw materials into the pulping machine; (3) adding an oxalic acid solution to react for 2 hours; (4) adding a potassium hydroxide solution to react for 2 hours; (5) adding industrial water, heating to 80 DEG C, adding formaldehyde and sodium sulfite, and reacting for 1 hour; (6) adding linoleic acid and alkyl phosphorus carboxylate, and reacting for 2 hours to obtain solid waste raw material slurry. and (7) feeding the solid waste raw material slurry into the pyrolyzing furnace for pyrolyzing to obtain fuel gas.

Description

technical field [0001] The invention relates to a solid waste treatment device and a treatment method thereof, in particular to a high calorific value carbon-containing solid waste treatment device and a treatment method thereof. Background technique [0002] Solid waste refers to solid or semi-solid waste generated by people in production, life and other behavioral activities. In a broad sense, it can be divided into carbon-containing organic solid waste and non-carbon solid waste. With the rapid development of society and economy, there are more and more solid wastes in cities, which has also caused great harm to the environment. The hazards mainly include: soil pollution, water pollution and air pollution. Therefore, how to treat solid waste harmlessly or even as a resource through reasonable means has become a hot issue in the application and development of social engineering technology today. [0003] At present, the treatment methods for solid waste mainly include s...

Problems solved by technology

However, the use of this incineration technology will produce a large amount of toxic components (mainly dioxins and organic volatiles) in the gas, and heavy metal substances in the solid residue, causing serious secondary pollution

At the same time, there is also the risk that the combustion performance of solid waste is unstable, which may easily lead to the interruption of system operation.
