Organic waste gasification treatment system and method

Abstract

The invention discloses an organic waste gasification treatment system and method. The system comprises a primary gasification device, a secondary gasification device, a spraying cooling device, a synthesis gas purifying device, a gas distributing device and a combustion device which are sequentially connected, wherein the combustion device connects with a combustion chamber; the primary gasification device connects with a gasification process air pipeline; the primary gasification device is fixedly arranged in the combustion chamber; the secondary gasification device connects with a high-temperature plasma torch device; and a supercharging water pump is arranged between the spraying cooling device and the synthesis gas purifying device. The organic waste gasification treatment system canconvert organic waste into gasification synthesis gas and discharge organic waste gasification residual inertial ash slag on site; and meanwhile, the gasification synthesis gas is recycled, so that stable operation of the system is realized, and pollution is avoided. Besides, the system is integrated and mounted in a standard container with high integration degree.

Description

technical field [0001] The invention belongs to the field of waste resource treatment, and in particular relates to a system and method for gasification treatment of organic waste. Background technique [0002] At present, the country is vigorously implementing the rural revitalization strategy, vigorously carrying out the improvement of the rural living environment, promoting the construction of healthy rural areas, and continuously improving the rural living environment. More and more attention has been paid to the treatment of organic wastes such as pesticide waste packaging and waste agricultural plastic mulch involved in non-point source pollution in agriculture and rural areas. At the same time, it is closely integrated with agricultural production, and small-scale, regional and seasonal local processing becomes necessary. In addition, in view of the current global pandemic of the COVID-19 coronavirus, medical waste urgently needs rapid and harmless treatment, and the...

Problems solved by technology

[0003] Therefore, due to the wide variety of the above-mentioned regional organic wastes, it is inevitable that the use of small-scale organic wastes that do not have the characteristics of resource utilization needs to be treated locally and nearby, causing pollution to the environment

Specifically, in the process of in-situ and nearby treatment, the gasification of organic waste will produce more macromolecular organic matter such as tar, and the energy of tar can account for 5%-10% of the energy of combustible gas. Condensation occurs and combines with water vapor and fly ash in the gas to form a viscous liquid, which leads to blockage of system pipelines and equipment, affecting the safe and stable operation of devices and systems; on the other hand, it is very difficult for tar to burn completely, and when it burns Particles such as carbon black will be produced during the process, causing serious damage to equipment and secondary pollution to the environment; therefore, it is necessary to develop a system and method for efficient gasification to avoid secondary pollution
