Embodiment 1

[0018] The turmeric waste residue used in the present embodiment is typical waste residue after extracting saponin from turmeric, its main components are as shown in Table 1, and its technological process is as follows figure 1 . In the figure, the turmeric waste residue is fed into the gasification device composed of the lower section 5 of the gasification device of Φ650 and the upper section 6 of the gasification device of Φ1000 in series through the Φ219 screw feeder 1. The height is 8.5 meters, and the three production process conditions are as follows: the first time, the ratio of air volume to added turmeric waste residue is 0.8Nm 3 Air / kg turmeric waste residue, the cross-sectional velocity of the air in the cold state on the air distribution plate is 0.5 m / s, the residence time of the turmeric waste residue in the gasification device is 7 seconds, and the temperature of the gasification device is controlled at 650 °C; the second time , the ratio of the amount of air t...

Abstract

The method of preparing combustible gas with waste peltate yam dreg includes feeding waste peltate yam dreg with one spiral feeder into one gasifying apparatus, and pyrolyzing waste peltate yam dreg at high temperature into combustible gas via controlling the ratio between air and the waste dreg and the staying time of the waste dreg inside the gasifying apparatus. The said method converts waste peltate yam dreg into combustible gas, and can reduce energy source waste and reduce environmental pollution caused by discarded waste dreg.

Description

Technical field [0001] The invention relates to a method for preparing combustible gas by using turmeric waste residue. Background technique [0002] The saponin industry is a new type of industry developed on the basis of the successful development of turmeric artificial planting in recent years. Saponin, also known as saponin, is mainly extracted from the roots of yam plants such as yam. Saponin and its products There are hundreds of kinds of pharmaceutical products, which can be used in the synthesis of hormone drugs. Saponin has the reputation of "gold in medicine". Turmeric waste residue is the waste residue produced during the extraction process of saponin. About 15 tons of turmeric waste residue is produced for every ton of saponin produced. With the continuous increase of saponin production, the resulting turmeric waste residue is discarded. The pollution problem has reached the point where it has to be solved. [0003] At present, the treatment of turmeric waste r...
