Aerating-sprinkling integrated system applied to sequencing batch type dry-fermentation device

Abstract

The invention discloses an aerating-sprinkling integrated system applied to a sequencing batch type dry-fermentation device. The aerating-sprinkling integrated system comprises an anaerobic dry fermentation reactor, a plurality of aerating sprinkling pipelines, a leachate collecting region, an air inlet pipe and a control center, wherein the aerating sprinkling pipelines are uniformly distributedat the two sides of the internal cavity of the anaerobic dry fermentation reactor, and tops of the aerating sprinkling pipelines are connected in series through a pipeline; spray headers are uniformlydistributed at single sides of the aerating sprinkling pipelines, aerating pore passages are formed in the other sides of the aerating sprinkling pipelines, and motor-driven rotatable baffles are arranged in internal chambers of the aerating sprinkling pipelines; the leachate collecting region is arranged at the bottom of the anaerobic dry fermentation reactor, and the bottom of the leachate collecting region is connected with the tops of the aerating sprinkling pipelines through spraying pipelines; and one end of the air inlet pipe is connected with an air blower, and the other end of the air inlet pipe communicates with a top pipeline of each aerating sprinkling pipeline. The application of the system is intelligently controlled, intelligent control on aerating and sprinkling can be achieved, the uniformity of aerating and sprinkling is improved, the fermentation space is saved, material charging and discharging are facilitated, the operation is simple and convenient, and the gas production rate is increased.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation, in particular to an integrated aeration and spraying system applied to a sequencing batch dry fermentation device. Background technique [0002] Anaerobic dry fermentation technology is used as a large-scale treatment of agricultural waste to realize resource utilization. However, this technology still has problems such as low hydrolysis efficiency in the anaerobic fermentation process, low methane production, and unstable process. Although the research on equipment development and fermentation influencing factors has been carried out, in-depth exploration of the feasibility, stability and efficiency of the process applied to the equipment is still needed in the application link. How to make the operation of the anaerobic dry fermentation equipment easier, the design more optimized, and the spray aeration process more uniform to increase the yield of biogas produced by anaerobic f...
