Pretreatment device in front of biomass separator

Abstract

The invention discloses a pretreatment device in front of a biomass separator which comprises a first-stage desanding system, a second-stage desanding system, a water circulation system and an organic matter catching and collecting system, wherein the first-stage desanding system is comprises a first-stage treatment bin, a sand blocking plate and a first-stage sand discharging spiral, and the second-stage desanding system comprises a second-stage treatment bin, a partition plate and a second-stage sand discharging spiral, the water circulation system comprises a circulating water pump and a circulating pipeline, and the organic matter fishing and collecting system comprises an organic matter fishing device, a first-stage collecting bin, an organic matter collector and a second-stage collecting bin. According to the pretreatment device in front of the biomass separator, water circulation is used as power for material transportation, biomass and other solid substances can be effectively separated by conducting two-time segmented gravity settling on precursor substances, and the pretreatment device is relatively simple in structure, high in separation efficiency and low in cost, and the method has a very wide application prospect in the aspect of separation of biomass solid wastes.

Description

technical field [0001] The invention belongs to the field of environmental treatment equipment, and in particular relates to a pre-pretreatment device for separating biomass components in solid waste. Background technique [0002] Domestic waste contains a large amount of biomass, and the main component is kitchen waste, which accounts for about 50% of domestic waste. Biomass waste is easy to breed microorganisms in nature, causing corruption, which emits an unpleasant smell, causes serious environmental pollution, and increases the difficulty of environmental governance. However, the current garbage classification work is not perfect. Biomass waste is often mixed in domestic waste, thereby introducing microorganisms that breed in it into domestic waste, which is likely to cause large-scale pollution and increase the difficulty of other solid waste disposal. [0003] As a kind of organic waste, biomass waste is easy to cause biological hazards such as bacterial growth on th...

AI Technical Summary

Problems solved by technology

At present, the difficulty in solving the utilization of biomass energy lies in the recovery of biomass solid waste. Due to the low efficiency of waste classification at this stage, other solid wastes that may have adverse effects on the later fermentation treatment may be mixed with biomass waste. Therefore, it is necessary to collect biomass solid waste. Separating waste from other solid wastes for post-processing
