Problems solved by technology

At the same time, it was found that the composition of the tar produced by garbage pyrolysis is also extremely complex. The composition analysis found that the tar contains hundreds of kinds of substances, including various organic acids, phenols, ketones, aldehydes, PAHs, etc., among which chlorine and heavy metal elements are common. On the high side, the water content is about 20%, and the calorific value is about 13-18MJ / Kg. At the same time, the high content of sulfides causes foul odor, and it is difficult to comprehensively utilize
Many factors make it difficult to make major breakthroughs in my country's waste pyrolysis and waste comprehensive utilization technologies

Embodiment 1

[0093] The organic waste pyrolysis system of the embodiment of the present invention uses municipal waste, Sichuan Furong coal and limestone as raw materials for waste treatment. The structure of the organic waste pyrolysis system is as follows Image 6 As shown, the garbage disposal process is as follows Picture 9 The composition analysis of municipal solid waste and Sichuan Furong coal is shown in the following table. The water content of the waste is 43%. The specific waste treatment methods are as follows:

[0094]

[0095]

[0096] 1. Municipal waste enters the site for waste pretreatment, and the large-size muck, glass, and metals contained in the waste that are not easily pyrolyzed or cannot be pyrolyzed are removed first.

[0097] 2. The garbage after removing the non-pyrolyzable substances is directly sent to the garbage dump for compression and dehydration, and then sent to the drying lifting tower for drying treatment to obtain the dried garbage;

[0098] 3. Transport the...

Abstract

The invention discloses an organic waste pyrolysis system and a method for treating organic waste through the organic waste pyrolysis system. The organic waste pyrolysis system comprises a screening machine, a spiral feeder, a drying hoist tower, a first cyclone separator and a pyrolysis reactor, wherein the screening machine, the spiral feeder, the drying hoist tower, the first cyclone separator and the pyrolysis reactor are communicated in sequence. The system can effectively restrain a secondary reaction of oil gas and increase the yield of tar, heat-storage non-heat-carrier radiant tubes are adopted for heating by the utilization of dividing wall heat exchanging, gas and solid heat carriers are not needed, the heat value of pyrolysis gas is increased, and meanwhile the organic waste pyrolysis system can be combined in a modularized mode, and is suitable for different amount of waste to be treated and easy to industrialize.

Description

Technical field [0001] The invention relates to an organic garbage pyrolysis system and a method for processing organic garbage by using the organic garbage pyrolysis system. Background technique [0002] With the acceleration of my country's modernization process, municipal solid waste has become an important factor restricting the rapid development of green cities. At present, the treatment methods of municipal waste in various countries in the world mainly include sanitary landfill, incineration, composting, pyrolysis and comprehensive waste treatment. However, my country's related waste classification and comprehensive waste utilization technologies are lagging behind. At present, the main waste disposal methods are sanitary landfills, with incineration and composting as supplementary methods. Moreover, with the advancement of science and technology and the enhancement of environmental protection awareness, the destructive effects of "incineration" and "landfilling" to the e...
