Quick curing treatment equipment and treatment method of anaerobic biogas residue

Abstract

The invention discloses quick curing treatment equipment of anaerobic biogas residue. An input end of a blower device is connected with an output end of an air inlet valve and an output end of an exhaust gas inlet valve; an input end of the exhaust gas inlet valve is connected with one side of an air chamber via a main pipeline; an output end of the blower device is connected with an input end of a heat exchange device and an input end of an exhaust gas outlet valve; the input end of the heat exchange device is further connected with a hot water supply; one path of an output end of the heat exchange device is connected with an input end of a hot air outlet valve; an output end of the hot air outlet valve is connected with one side of the air chamber via the main pipeline; the other path of the output end of the heat exchange device is connected with an input end of a temperature control valve; an output end of the temperature control valve is connected with a main pipeline; the other side of the air chamber is communicated with an anaerobic biogas residue stowing cabin via an air pipe; and the air valves, the blower device, the heat exchange device and the temperature control valve are controlled by a PLC (programmable logic controller). The invention further discloses a quick curing treatment method of the anaerobic biogas residue. According to the equipment and the method, the anaerobic biogas residue can be cured quickly, the curing time is shortened, and the curing energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of anaerobic biogas residue treatment, in particular to an anaerobic biogas residue rapid aging treatment equipment and a treatment method. Background technique [0002] With domestic organic waste, kitchen waste, livestock and poultry manure, agricultural waste, garden waste, etc. as raw materials, the anaerobic fermentation process is becoming more and more mature. During the anaerobic fermentation process, the organic matter not only achieves harmless treatment, but also obtains clean energy biogas, and improves the ecological environment, and the biogas residue produced by anaerobic fermentation can be developed into high-quality organic fertilizers, which can be used in farmland to improve soil, Increase soil fertility. [0003] There are various anaerobic fermentation processes, which can be divided into wet anaerobic fermentation and dry anaerobic fermentation according to their solid content; accord...

Problems solved by technology

However, in general, due to the high moisture content of the fermentation residue after anaerobic fermentation, it is not conducive to direct application; in addition, according to different fermentation processes, the content of undegraded organic matter after anaerobic fermentation varies, especially the wet fermentation has a hydraulic short circuit As a result, fresh unfermented materials are mixed in the output, and direct application will cause the risk of burning seedlings and polluting the environment
