Description

Hydropower recovery device for waste solid slag organic matter

technical field

The utility model relates to a hydraulic recovery device for garbage solid slag and organic matter, which belongs to the technical field of garbage treatment.

Background technique

Organic waste includes food waste, kitchen waste, domestic waste and other waste with high organic matter content, which has the characteristics of high moisture, grease (especially food waste), organic matter, and high salt content, and is easy to rot and deteriorate, spread germs, and emit stench.

At present, the main treatment technologies of organic waste at home and abroad mainly include landfill, incineration, composting, physical crushing, feed (refers to kitchen waste) and anaerobic digestion treatment technology. The anaerobic digestion treatment technology has the advantages of low energy consumption, recovery of clean energy such as biogas, and reduction of environmental impact. It is currently the most advanced organic waste treatment technology.

Anaerobic technology is used to treat organic waste. In order to make full use of the organic matter in the follow-up anaerobic process, the light matter and some heavy matter in the waste are removed through pre-sorting, and then the remaining materials are crushed and pulped. The organic matter in the organic waste slurry is extracted by cooking and other methods, and the solid-liquid separation is carried out on the slurry. The liquid phase can be treated with oil extraction (kitchen waste), and the treated liquid phase material will enter the subsequent anaerobic fermentation system. Anaerobic digestion is carried out, and the separated solid phase slag is landfilled.

CN203862664U discloses a kind of food waste organic matter recycling conveying device, although this device has realized the partial separation of organic matter, but due to the limited distance between the spiral travel, the rinsing time cannot be guaranteed, the rinsing effect is poor, and only through the Fixed sieve filtrate is easy to block the sieve, and there are problems such as cumbersome maintenance. CN203621081U discloses a cooking kettle for processing food waste, which uses steam heating and pressurization to recycle organic matter in the food waste. Although the device has a simple structure and low cost, the equipment runs with high energy consumption and is economical. In particular, this type of equipment is operated in a sequential batch mode, which cannot achieve continuous operation, and cannot be adapted to the requirements of connection processing, and the production efficiency cannot be further improved. Furthermore, the recovery of organic matter in garbage mainly relies on rinsing, cooking, etc. to extract the organic matter in the kitchen waste slurry. There are many organic matters, on the one hand, the organic matter in the garbage cannot be fully separated, on the other hand, it also causes a large amount of solid slag landfill, which cannot further recycle capacity.
