Embodiment Construction

[0017] The detailed technological process of the method for preparing biomass fuel by using kitchen waste according to the present invention is:

[0018] 1. Unload the food waste collected by the food waste transport vehicle into the self-conveyor unloading hopper, where the oil and water mixture mixed in the food waste flows into the inlet of the mixed liquid pump, and the wet material is sent into the feeder through the conveyor Crusher, after the crusher crushes the material, the chain plate conveyor sends the material to the magnetic separator to remove iron and other objects, and then the chain plate conveyor transports it to the screen surface of the vibrating separator. The screen aperture is 15 mesh. At this time, more than 95% of the useful materials fall into the feed port of the dehydrator through the screen under the vibration force of the vibrating separator, and the harmful materials that do not pass the screening are sent to the waste collection barrel. The disc...

Abstract

The invention relates to a method for recycling resources, in particular to a method for preparing biomass fuel from kitchen waste resources. The method for preparing biomass fuel from kitchen waste according to the present invention comprises sorting and crushing the kitchen waste, then dehydrating and deoiling, and anaerobically fermenting the solid materials in the kitchen waste after extracting the oil, and degrading the produced biogas Recycling, solid-liquid separation of the biogas slurry, the separated biogas residue is mixed with sludge, straw and other biomass materials, and dried and briquetted to make biomass fuel. The invention recycles kitchen waste and turns waste into treasure. It not only realizes the harmless and reduction treatment of kitchen waste, but also treats biomass waste such as sludge and straw, and the obtained products are completely burned without any waste. Secondary pollution, realize the comprehensive treatment of various wastes.

Description

technical field [0001] The invention relates to a method for recycling resources, in particular to a method for preparing biomass fuel by using kitchen waste resources. Background technique [0002] Kitchen waste is domestic waste generated by residents' diet, mainly including rice and flour food residues, vegetables, animal and vegetable oils, meat, bones, etc. Improper disposal of kitchen waste can easily emit stench, spread germs, and affect ecological security and food safety. [0003] At present, domestic and foreign countries have begun to research and develop the process of resource utilization of food waste. There are probably the following methods for the treatment of food waste: one is the landfill method. This method landfills the usable matter, has a very low level of resource utilization, limited processing capacity, and unsatisfactory benefits. One is feed. This method uses biotechnology to make feed from kitchen waste. The production process is complicated,...
