Problems solved by technology

[0005] Aiming at the deficiencies of the existing oil extraction process, the present invention provides a kitchen waste oil extraction process method and system to solve the problem of incomplete oil extraction in the prior art, and a large amount of oil enters the anaerobic fermentation process unit, resulting in anaerobic fermentation process. Oil accumulation in the fermentation system leads to the problem of unstable process operation; at the same time, increasing the output of oil can also improve the utilization efficiency of food waste resources, and promote the growth of the comprehensive economic benefits of the food waste treatment plant

Embodiment Construction

[0042] An oil extraction treatment process method for kitchen waste treatment comprises the following steps: filtration, separation, and hydrolysis;

[0043] In the filtration and separation step, in the pretreatment system (preferably, the pretreatment of kitchen waste includes crushing, sorting (separating large pieces of metal), etc., generally conventional treatment), rinse with water and filter, The solid slag that cannot be washed out by water can be directly landfilled. Preferably, the water pressure of the water washing is 0.01-2 standard atmospheres. When in use, the water is generally washed directly to the kitchen waste, and the filtrate and the filtrate are formed by filtration. Slurry, the filtrate passes through the smaller filter hole, the slurry passes through the larger filter hole, and the slag that cannot pass through the larger filter hole is the slag, which can be directly used for landfill, the filtrate enters the oil extraction system to extract oil, and ...

Abstract

The invention relates to a kitchen waste oil extraction treatment process method and system, the method comprises the following steps: washing with water in kitchen waste pretreatment, filtering the liquid to extract oil, hydrolyzing the slurry and then extracting oil, and the system comprises a slurry preparation part, an oil extraction part and a hydrolysis acidification tank. Through water washing and secondary oil extraction, the oil extraction rate can be greatly improved, interference of oil to a pretreatment system is reduced, and the treatment efficiency of the whole system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment technology, in particular to a process method and system for oil extraction from kitchen waste. Background technique [0002] At present, the main modes of harmless treatment of food waste in the country include anaerobic fermentation, composting, landfill treatment, and animal protein feed. However, the kitchen waste treatment projects generally have the problems of difficult selection of process flow, insufficient project profitability and low comprehensive utilization efficiency. Relevant literature shows that more than 76.1% of the kitchen waste treatment projects that have been operating or are under construction have chosen the anaerobic fermentation process, in order to enhance the sustainable operation ability of the project through the benefits of comprehensive utilization of biogas. The main benefits that can be excavated in the kitchen waste project are the deep process...
