Problems solved by technology

Therefore, there are still some problems in the food waste pretreatment system adopted by waste power plants. The conventional food waste pretreatment system used is the pretreatment process of anaerobic fermentation technology (including crushing, heating, pulping, etc.), Due to the crushing process, the solid phase organic matter is dispersed into the leachate, which increases the difficulty of leachate treatment, and the degree of solid-liquid separation is average

Embodiment Construction

[0045] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.

[0046] Referring to the accompanying drawings, it can be seen that a food waste pretreatment system includes a bag breaking chamber a, a rough separation chamber b, a fine separation chamber d, an oil extraction chamber f, and a solid phase collection and delivery system;

[0047] The coarse separation chamber b is located below the bag breaking chamber a; the fine separation chamber d is arranged next to the coarse separation chamber b;

[0048] The oil lifting chamber f is located below the coarse separation chamber b;

[0049] The solid phase collection and delivery system is located on the side of the rough separation chamber b, the fi...

Abstract

The invention discloses a kitchen waste pretreatment system. The kitchen waste pretreatment system comprises a bag breaking chamber, a coarse separation chamber, a fine separation chamber, an oil extraction chamber and a solid phase collecting and conveying system; the coarse separation chamber is positioned below the bag breaking chamber; the fine separation chamber is arranged on the side of the coarse separation chamber; the oil extraction chamber is positioned below the coarse separation chamber; the solid phase collecting and conveying system is positioned on the sides of the coarse separation chamber, the fine separation chamber and the oil extraction chamber; a vibrating screen and a leachate spraying device are arranged in the coarse separation chamber; the vibrating screen is obliquely arranged; the leachate spraying device is arranged above the vibrating screen; a slurry temporary storage tank is positioned below the vibrating screen; a solid phase collecting chamber is positioned at the tail of the vibrating screen; the solid phase collecting and conveying system comprises a collecting hopper and a spiral conveying device; the spiral conveying device is obliquely arranged; the collecting hopper is connected above a feeding hole of the spiral conveying device; and the leachate temporary storage tank is positioned below the solid phase collecting chamber. The kitchen waste pretreatment system have the advantages of good solid-liquid separation degree and high crude oil extraction rate. The invention further discloses a pretreatment method of the kitchen waste pretreatment system.

Description

technical field [0001] The invention relates to the field of domestic solid waste treatment, more specifically it is a food waste pretreatment system, more specifically it is a food waste pretreatment system suitable for a collaborative incineration process. The invention also relates to a pretreatment method of the kitchen waste pretreatment system. Background technique [0002] With the implementation of the domestic waste classification policy, the treatment of kitchen waste has gradually been valued by various places. At present, the treatment of food waste mainly adopts the recycling process route of fermentation biogas: the food waste is pulped and mixed with specific strains, and the characteristics of microorganisms to decompose organic matter and generate biogas in an anaerobic environment are used to treat food waste . Since the marketability of organic fertilizer products made from biogas residues in this process is not high, this process can only recover part o...
