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

[0055] Table 2

[0056]

[0057] 1. Garbage pretreatment for entering the site. After entering the site, large-size dregs, glass and metals and other substances that are not easy to pyrolyze or cannot be pyrolyzed are removed first;

[0058] 2. The garbage after removing the difficult-to-pyrolyze materials is directly sent to the garbage dump for compression and dehydration, and then sent to the pyrolysis reactor;

[0059] 3. Control the ratio and amount of gas and air entering the radiant tube, control the temperature of the pyrolysis furnace, and ensure that the temperature in the pyrolysis chamber is about 680°C;

[0060] 4. Control the rotat...

Abstract

The invention discloses a pyrolysis reactor and a method for treating rubbish with the pyrolysis reactor. The pyrolysis reactor comprises a pyrolysis oil gas outlet, heat accumulating type radiant tubes, oil gas guiding-out pipelines and a gas collecting tube. The heat accumulating type radiant tubes are arranged in multiple layers in the height direction of the pyrolysis reactor, and each layer includes multiple heat accumulating type radiant tubes which are parallel to one another in the horizontal direction. The oil gas guiding-out pipelines are arranged in multiple layers in the height direction of the pyrolysis reactor, each layer includes multiple oil gas guiding-out pipelines which are parallel to one another in the horizontal direction, and the surfaces of the oil gas guiding-out pipelines are provided with through holes. The gas collecting tube is communicated with the oil gas guiding-out pipelines and the pyrolysis oil gas outlet. The pyrolysis reactor can effectively restrain a secondary reaction of oil gas and increase the tar yield; in addition, the heat accumulating type heat-carrier-free radiant tube heating technology is adopted, no gas or solid heat carrier is needed, and the heat value of pyrolysis gas is increased; meanwhile, the pyrolysis reactor has the advantages that few devices are used, operation is easy, and the fault rate is low.

Description

technical field [0001] The present invention relates to pyrolysis reactors. 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, urban waste treatment methods 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 waste comprehensive utilization technologies lag behind. At present, the main treatment method of waste is sanitary landfill, supplemented by incineration and composting. Moreover, with the advancement of science and technology and the enhancement of environmental protection awareness, people have increasingly recognized the destructive effects of "incineration" and "landfilling" on the environment and the threat to human health. A new type of technology to replace "incinera...
