Food waste separating apparatus

Abstract

The invention provides a food waste separating apparatus, belonging to the technical field of environmental protection apparatuses. The food waste separating apparatus is such structured that a feed pump is connected with a solid-liquid separation unit, the solid-liquid separation unit includes a solid-liquid separation device, a feed liquid tank is arranged at a permeation side of the solid-liquid separation device and is connected with a preliminary oil-water separation unit through a feed pipe, the preliminary oil-water unit comprises a separator, the separator is composed of an upper plate and a lower plate, holes are perforated in the lower plate, an outlet of the separator is connected with a waste oil separation unit, the outlet of a cavity is connected with a waste water separation unit, the waste oil separation unit includes a hydrophobic oil-water separation membrane element, the waste water separation unit includes a hydrophilic oil-water separation membrane element, and the waste oil separation unit and the waste water separation unit are respectively connected with the feed liquid tank through a pipeline with a pump to allow the feed liquid to return to the feed liquid tank. The food waste separating apparatus can thoroughly separate solids, oil and water in food waste to protect the environment.

Description

technical field [0001] The invention provides a catering waste separation device, which belongs to the technical field of environmental protection devices, and in particular relates to a device capable of separating solids, water and oil in catering waste. technical background [0002] Catering waste is a kind of domestic waste formed by residents in the process of living consumption. Its sources are mainly restaurants, canteens, street snacks and other places, and various organic substances contained in it are easily corroded in summer; The water content is very large, which is easy to cause pollution during the collection and transportation of garbage; at the same time, food waste is the main source of leachate in landfill sites, and is also an important cause of air pollution and fly breeding; pigs and pigs fed by food waste The flow of refined swill oil to the market has seriously endangered the health of citizens. Catering garbage wastewater is directly discharged into...

Problems solved by technology

At present, the industrialized production of biodiesel has started at home and abroad, and most of them adopt the homogeneous catalytic transesterification method, that is, a liquid catalyst, to make fatty acid glycerides and methanol transesterify to generate fatty acid methyl esters (biodiesel) and glycerin, but there are many Disadvantages, if liquid alkali is used as catalyst, raw oil and methanol must be strictly dehydrated, otherwise it is easy to form emulsion (Cao Hongyuan, Cao Weiliang, Zhang Jingchang. Solid acid Zr(SO4) 2 4H 2 Preparation of Biodiesel Catalyzed by O[J].Journal of Beijing University of Chemical Technology,2005,32(6),61-63)
