Food waste hydrolysis and spray explosion system

Abstract

A food waste hydrolysis and spray explosion system comprises a spray explosion tank and an explosion bearing cabin disposed below the spray explosion tank. The spray explosion tank comprises a housing of the spray explosion tank. A feeding port, a thermometer, and a mechanical sealing device are disposed at the top of the housing of the spray explosion tank. An agitator shaft penetrates through the mechanical sealing device and extends into the housing of the spray explosion tank. A first helical ribbon agitator located in the housing of the spray explosion tank is disposed on the agitator shaft. At least two annular air inlet devices are disposed on a side wall of the housing of the spray explosion tank, and a pressure gauge and a discharge port are disposed at the bottom of the housing of the spray explosion tank. A catalyst in the tank is uniformly mixed with a material by stirring, and mechanical processing can be performed on the material after spray explosion. In addition, heat energy of high-temperature and high-pressure steam is effectively recovered and utilized, and waste gas is recovered.

Description

technical field [0001] The invention relates to the field of municipal solid waste treatment, in particular to a kitchen waste hydrolysis spray explosion system, which is used for hydrolysis spray explosion treatment of kitchen waste. Background technique [0002] Food waste mainly contains starch, lignin, cellulose, protein, and lipids, and its macromolecules are degraded into small molecules in a hydrolysis spray tank. Most of the existing explosion-proof tanks are filled with kitchen waste and catalysts from the feed port, and high-temperature (180°C) high-pressure (2MPa) steam is introduced from the discharge port through the pores to hydrolyze the organic waste in the tank. , The organic matter drops rapidly from the high pressure to the normal pressure state from the circular discharge port at the lower end of the tank, and a spray explosion effect is generated to break the organic matter. [0003] The following problems exist in the conventional detonation system: ...

AI Technical Summary

Problems solved by technology

[0004] ①The steam inlet is single, and the steam cannot be uniformly and quickly transported to every corner of the tank, which often causes the temperature at the inlet to be too high, and some organisms do not undergo hydrolysis, but instead undergo pyrolysis reactions

[0005] ②Uneven distribution of steam leads to uneven distribution of pressure field, unbalanced reaction, and some organic matter does not even undergo hydrolysis reaction

[0006] ③ The organic matter is in a solid state, and it cannot be fully mixed with the catalyst in the explosion tank, resulting in an unbalanced reaction

Some local reactions are strong, and there are too many catalysts to waste; some parts have no catalysts, resulting in slow reactions

[0007] ④The blasting port is facing the ground and there is no receiving device. After the blasting, the material must be collected manually. After the blasting, a large amount of high-temperature exhaust gas is generated, which brings environmental pollution and wastes the heat energy of the high-temperature steam
