Device for supplying heat and recovering carbon dioxide by using fermented manure

Abstract

The invention relates to a device for supplying heat and recovering carbon dioxide by using fermented manure. A water pipe is arranged on the top of a fermented manure tank; the water pipe is connected with a water supply valve and used for sprinkling water to improve the humidity of fermented manure materials; the bottom of the fermented manure tank is provided with an air vent which is connected with an air compressor through an air pipeline; capillary water paths are arranged in the fermented manure tank at intervals; the capillary water paths are connected with a pipeline to form a closed loop; the pipeline is connected with an external heat supply pipeline; a heating module is arranged on the pipeline, and a temperature probe is arranged in the pipeline; a humidity probe is arranged at a 1 / 3 position of the lower part of the fermented manure tank; the temperature probe and the humidity probe are respectively connected with a PLC (Programmable Logic Controller); the PLC is connected with the water supply valve, the heating module and the air compressor. The device disclosed by the invention not only can be used for obtaining heat generated in a composting process, controlling the temperature in the manure in an appropriate level to create a most appropriate composting environment and shortening the fermented manure composting time, but also can be used for recovering carbon dioxide formed in an oxidation process as a gaseous fertilizer.

Description

technical field [0001] The invention relates to an aerobic biological compost, in particular to a device capable of using fermented compost to supply heat and recover carbon dioxide. Background technique [0002] Aerobic biocomposting is the process of decomposing organic macromolecules into small molecular humus under aerobic conditions by utilizing the action of various microorganisms. According to the first law of thermodynamics, the same mass of organic matter releases the same amount of energy when it is burned outside the body and oxidized inside the body: the energy released by oxidative decomposition of 1 gram of glucose is 17.15 kJ; the energy released by oxidative decomposition of 1 gram of fat is 38.91 kJ The energy released by oxidative decomposition of 1 gram of protein is 18 kilojoules; according to this calculation, 1 ton of organic waste can release at least the heat equivalent to 90 kilograms of standard coal after aerobic composting. [0003] In the case o...
