Solid garbage treatment device

Abstract

The invention discloses a solid garbage treatment device. The solid garbage treatment device comprises an organic solid garbage decomposition device (1), a methane dehydration device (2) and a methanedrying device (3), wherein the organic solid garbage decomposition device (1) comprises a tank body (4), an induced draft fan I (5), a motor A (6) and a single-screw conveying device (7); the methanedehydration device (2) comprises a bearing seat (21), a vertical rotary drum (22), a speed reducer B (23), a motor B (24), a driving gear B (25) and a driven gear B (26); the methane drying device (3) comprises a horizontal rotary drum (35), a supporting roller carrier (36), a speed reducer C (37), a motor C (38), a methane collecting tank (39), an induced draft fan II (40), a driving gear C (41)and a driven gear C (42). The solid garbage treatment device has the beneficial effects that the organic solid garbage is treated in an environment-friendly manner, the methane purity is improved, the methane yield is increased, the organic solid garbage treatment efficiency is improved, and waste is turned into wealth.

Description

technical field [0001] The invention relates to the technical field of organic solid waste treatment, in particular to a solid waste treatment device. Background technique [0002] There are many types of organic solid waste, among which the most common one is solid waste in catering waste. Catering waste is also called kitchen waste (commonly known as swill, swill), which refers to the general term for leftovers, table waste and kitchen scraps. Its main components are rice, flour, starch, bone, meat, oil, skin, thorns, scales, etc., which are rich in vitamins, starch, protein, oil, dietary fiber, fatty acids, sugar, salt and other nutrients, as well as calcium, Sodium, magnesium, potassium, iron and other minerals, food waste is a living substance formed by residents in the process of living consumption. After a large amount of organic solid waste accumulates, it will stink after a period of time and breed flies at the same time, polluting urban air very much. The scientif...

AI Technical Summary

Problems solved by technology

Since the collected methane contains a large amount of water, it cannot be used directly at all, and requires dehydration and drying treatment respectively. However, the existing dehydration device and drying device have the defects of incomplete dehydration and incomplete drying respectively, and the purity of the obtained methane is low.

In addition, the existing decomposed organic solid waste also has the following defects: 1. The collected methane needs to be processed by a dehydration device and a drying device respectively, and the finished product methane is not continuous, which reduces the efficiency of organic solid waste treatment

2. The volume of organic solid waste is large, so that organic solid waste does not have sufficient contact with microorganisms at all, and it takes a long time to decompose organic solid waste, which reduces the treatment efficiency of organic solid waste and also reduces methane production
