Fixed aerobic composting reactor

Abstract

The invention relates to a fixed aerobic composting reactor which comprises a reaction chamber, a bracket, a water tank, a water pump, a filter and a fan. The reaction chamber is a closed box body; the top of the box body is provided with a detachable top cover; both sides of the top cover are respectively provided with a water inlet and an air inlet and a water distribution board and an air distribution board are respectively arranged in the inlets; ventilation columns and spray nozzles are uniformly distributed in the reaction chamber at intervals; the ventilation columns adopt sleeve structures; air vents are respectively arranged on the pipe walls of inner pipes and outer pipes; the ventilation quantity can be regulated by rotating the inner pipes; the upper part of the reaction chamber is provided with an exhaust port and the exhaust port is communicated with an exhaust plate on the ground; the filter is a closed box body; a gauze filter plate and a filter-paper filter plate are respectively arranged in the filter; and an outlet of the fan is connected with the air inlet of the top cover by a pipeline. The fixed aerobic composting reactor has the advantages that the reactor has simple structure and low cost and is convenient to use; due to the adoption of fixed composting, the heat loss is reduced, the high-efficiency fermentation of a fertilizer is ensured, the aerobic composting is strengthened and the energy-saving, environmental-friendly, economic and high-efficiency composting effects are implemented.

Description

technical field [0001] The invention relates to environmental protection mechanical equipment, in particular to a fixed aerobic composting reactor. Background technique [0002] With the rapid development of the economy, the generation of biomass solid waste such as crop straw, urban and rural domestic waste, landscaping waste, and livestock and poultry manure has increased sharply. In the past, the main ways to deal with biomass solid waste were stacking and incineration. Stacking could easily pollute groundwater, and incineration would seriously pollute the atmosphere. On the other hand, with the excessive application of chemical fertilizers and the sharp reduction in the application of traditional organic fertilizers, the problem of soil compaction has become more and more serious. These biomass solid wastes contain a large amount of organic matter and elements such as nitrogen and phosphorus, which can not only provide essential crops Nutrients, and can effectively alle...

Problems solved by technology

The composting device is an important carrier for composting and composting reactions. However, there are many problems in the existing reactors, such as: uneven distribution of water, easy agglomeration of fertilizers during the process of stirring and turning, energy consumption, and oxygen supply efficiency. It is not high, and the odor generated in composting cannot be solved or the cost of deodorization is high, which also limits the promotion and practical application of composting methods in the treatment of organic solid waste to a certain extent.
