Movable rotary drum type composting reactor

Abstract

The invention belongs to the field of solid wastes recycling utilization, and in particular relates to a movable rotary drum type composting reactor. The composting reactor is horizontal rotary drum type, wherein one or a plurality of 'V'-shaped baffles are arranged in the inner side of a rotary drum, so that materials can be lifted along with the rotary drum; one end of the rotary drum is a material inlet / outlet, a central pipe is inserted from the other end of the rotary drum, and a plurality of dispersion baffles with different angles and a sensor chamber with a sensor are assembled on the upper part of the pipe; a vent pipe is arranged in the central pipe, and is connected with a plurality of air distribution pipes, and small holes are densely distributed on the air distribution pipes; a temperature sensor is assembled on the lower part of the central pipe; the working time and efficiency of the reactor are controlled through setting the senor data or time and the like; and the devices are all assembled on a rack with movable wheels. The reactor can be used for effectively solving the problems of difficult uniform mixing of solid materials and poor mass transfer and heat transfer and can realize the real-time monitoring and feedback controlling of critical parameters, and thus, the composting reaction efficiency is effectively improved; and in addition, the reactor also has the characteristic of convenience in moving.

Description

technical field [0001] The invention belongs to the field of resource utilization of solid waste, and in particular relates to a movable drum type composting reactor. Background technique [0002] In recent years, with the rapid development of my country's economy, the resulting environmental pollution problems have become increasingly prominent. In particular, the growth rate of biomass waste such as kitchen waste, fruit and vegetable waste, and yard waste is very fast. This kind of waste has a scattered source, a large amount, is prone to corruption and odor, and breeds pathogenic bacteria, which has brought certain impacts on the ecological environment and human health. threat. In addition, due to the characteristics of biomass waste, it is not suitable for conventional landfill or incineration. Aerobic composting is one of the effective ways to deal with this kind of biomass waste. It can also produce organic fertilizers while treating waste, which is a good resource t...

AI Technical Summary

Problems solved by technology

Therefore, some small-scale composting reactors have been developed at home and abroad, but these devices either have shortcomings such as incomplete mixing, high energy consumption, poor heat and mass transfer, or lack of monitoring and control of process parameters, resulting in low composting efficiency. , poor product quality, etc.
