Container type dry fermentation system

Abstract

The invention belongs to the technical field of garbage recycling and the development and the utilization of biological energy sources and especially relates to a container type dry fermentation system. The convenience in charging and discharging is achieved through a manner that a stainless steel cover is matched with a wheeled movable dry fermentation device, and an opening of the movable dry fermentation device is used for charging and the discharging is carried out by directly withdrawing a bottom perforated baffle, wherein the stainless steel cover can vertically stretch out and draw back and is fixedly arranged on the ceiling of a fermentation room; the temperature control in a dry fermentation process is achieved through a temperature-controlling device built in the ground surface,meanwhile, a foam plastic board heat-insulating material is applied to the cover body, therefore, the temperature of the dry fermentation process is maintained; water grooves are paved on the ground surface along the bottom contour of the stainless steel cover, so that an anaerobic environment is guaranteed by using a water seal manner; and the leachate circulation is achieved through a leachate circulation system, i.e. a leachate collecting tank, pumps and spraying nozzles. According to container type dry fermentation system, the difficulty in the charging / discharging of dry fermentation canbe solved, meanwhile, the environmental conditions required for the dry fermentation process can be controlled, so that the efficiency of the dry fermentation is increased, and meanwhile, the transportation cost and the energy consumption are reduced.

Description

technical field [0001] The invention belongs to the technical field of waste recycling and bio-energy development and utilization, and in particular relates to a container-type dry fermentation system. Background technique [0002] Under the background of energy shortage, global warming and deterioration of ecological environment, energy saving and emission reduction, efficient use of resources and development of new energy have become the top priority of the world. Dry fermentation is also called high solid anaerobic digestion, which means that the total solid content is about A relatively new technique for fermenting at 20% or higher. There are many types of anaerobic dry fermentation substrates, and most organic solid waste can be used as substrates for anaerobic dry fermentation, such as weeds, trees, plant leaves, fruit and vegetable residues, organic solids in municipal solid waste, Aquatic organisms, poultry manure, etc. However, the composition of different substra...
