Reaction device for comprehensively measuring biodegradability of material and use method of reaction device

Abstract

The invention provides a reaction device for comprehensively measuring the biodegradability of a material. The reaction device comprises an equipment frame, an electric control cabinet and a reaction bin single body, the upper side of the reaction bin single body is a reaction bin main body, and the lower side is a material receiving trolley. The top of the reaction bin main body is sealed by a bin cover; an electric heating plate and heat-insulating cotton are attached to the side wall; a stirring paddle is arranged in the reaction bin main body; an air inlet and an air outlet are respectively formed in the front and rear walls, the lower part is a a discharging mechanism, and the electric control cabinet independently controls the reaction conditions of all the reaction bin monomers respectively. The invention also relates to a use method of the biodegradability evaluation material, and the biodegradability evaluation in three aspects of material degradation rate, disintegration rate and ecological non-toxicity test can be realized. The reaction device has the advantages that automatic discharging and automatic stirring can be achieved, odor and heat leakage in the bin are reduced, meanwhile, efficient fermentation of materials is achieved, and the measuring method can comprehensively detect the degradability of the materials from multiple aspects. The data obtained by the device is high in accuracy, the result credibility is high, and the device can be used as a scientific device for evaluating the degradability of the material.

Description

technical field [0001] The present application relates to the field of biodegradability measurement of materials, in particular to a reaction device for comprehensively measuring biodegradability of materials and its application method. Background technique [0002] As the pressure on global resources, energy conservation and environmental protection continues to increase, consumers' demand for biodegradable materials is increasing. Biodegradability means that under the action of microorganisms, the material can be decomposed into carbon dioxide, water, mineralized inorganic salts contained in the raw material itself, and new biomass. Compost is rich in microorganisms such as bacteria, fungi, and actinomycetes, which can reflect the biodegradability of materials in the natural environment to a certain extent, so it is listed as a recommended method for evaluating biodegradability internationally.

Problems solved by technology

Several groups of independently installed detection devices arranged side by side need to occupy a large space. If the volume of the reaction chamber containing the experimental materials inside is compressed, it will be difficult to achieve high-temperature fermentation due to the limited volume capacity of the small pile in the reaction chamber, resulting in measurement inaccurate result
