Description
技术领域technical field
本实用新型涉及可再生能源利用领域，具体涉及一种太阳能恒温沼气池联合燃气壁挂炉的大棚供热系统。The utility model relates to the field of renewable energy utilization, in particular to a greenhouse heating system of a solar constant temperature biogas pool combined with a gas wall-hung boiler.
背景技术Background technique
沼气池的建设对生态环境保护和改善、资源循环利用方面有着重要的作用。但是目前农村沼气建设与运用中存在诸多问题，特别是没有保温与加热措施，使得当气温较低时沼气池基本处于停止产气状态，严重限制了沼气池的使用率。有的地区在入冬前会采取沼气池上搭建简易温棚或者用秸秆、塑料薄膜覆盖沼气池保温的措施，但是效果并不理想。The construction of biogas digesters plays an important role in the protection and improvement of the ecological environment and the recycling of resources. However, there are many problems in the construction and application of biogas in rural areas at present, especially the lack of heat preservation and heating measures, which makes the biogas digester basically stop producing gas when the temperature is low, which seriously limits the utilization rate of the biogas digester. In some areas, simple greenhouses are built on the biogas digesters or covered with straw and plastic film to keep the biogas digesters warm before winter, but the effect is not ideal.
在温室大棚种植蔬菜时，土壤温度是提高作物产量和质量的关键因素。土壤的升温方式主要有直接和间接两种。作为当前温室大棚加温采用的主要方式，间接方式是将散热器的热量通过对流和辐射的方式传给室内空气，以提高室内温度，然后室内空气再通过对流和辐射将热量传递给土壤层，从而间接提高土壤温度，但是植物的呼吸作用与光合作用使室温受到限制，从而使得间接方式提高土壤温度的能力也有限，特别是对于植物的主要根群深度处(20-30cm)，温度达不到植物的生长要求，同时由于间接加热主要采用锅炉或燃煤炉子等装置提供热源，会给环境造成一定的污染。而直接方式是将热水或热空气通过管式换热器与土壤层换热后，直接将热量传递给土壤层，使得土壤层升温，传热高效，具有节能环保的优势。When growing vegetables in greenhouses, soil temperature is a key factor in improving crop yield and quality. There are two main methods of soil heating: direct and indirect. As the current main method of heating greenhouses, the indirect method is to transfer the heat of the radiator to the indoor air through convection and radiation to increase the indoor temperature, and then the indoor air transfers heat to the soil layer through convection and radiation. Thereby increasing the soil temperature indirectly, but the respiration and photosynthesis of plants limit the room temperature, so that the ability to increase the soil temperature indirectly is also limited, especially for the depth of the main root group of plants (20-30cm), the temperature cannot reach At the same time, because indirect heating mainly uses boilers or coal-fired stoves to provide heat sources, it will cause certain pollution to the environment. The direct method is to exchange heat with the soil layer through the hot water or hot air through the tube heat exchanger, and then directly transfer the heat to the soil layer, so that the soil layer is heated up, the heat transfer is efficient, and it has the advantages of energy saving and environmental protection.
公布号为CN101948743A的中国发明专利“一种农村沼气池-大棚联用的方法”，将沼气池安装在大棚内部，沼气池产生的沼气作为能源，冬季以大棚对沼气池进行保温；以气体收集装置收集住宅区燃烧沼气产生的CO2气体；利用气体释放装置按比例将CO2释放到大棚中，以提高大棚内CO2浓度而提高农作物产量；以大棚中农作物的残叶和秸秆做沼气池发酵的原料。本发明实现了资源的合理配置与利用，以最低的能耗解决了沼气池的保温问题；通过气体吸收装置将CO2气体进行收集，减少CO2排放量，同时提高大棚中CO2的浓度。但其没有沼气池加热装置，不能使沼气池维持在产气率较高的发酵温度下，同时沼气燃烧后的烟气余热没有进一步利用，造成热量损失，也未涉及余热加热土壤层装置及烟气过滤装置。The Chinese invention patent with the publication number CN101948743A "A method for combined use of rural biogas digesters and greenhouses" installs the biogas digesters inside the greenhouses, and the biogas generated by the digesters is used as an energy source. In winter, the greenhouses are used to keep the biogas digesters warm; The device collects CO 2 gas produced by burning biogas in residential areas; uses the gas release device to release CO 2 into the greenhouse in proportion to increase the CO 2 concentration in the greenhouse and increase crop yield; use the residual leaves and straw of crops in the greenhouse as a biogas digester Raw material for fermentation. The invention realizes the rational allocation and utilization of resources, solves the heat preservation problem of the biogas pool with the lowest energy consumption; collects CO2 gas through the gas absorption device, reduces CO2 emissions, and simultaneously increases the CO2 concentration in the greenhouse. However, it does not have a biogas digester heating device, which cannot maintain the biogas digester at a fermentation temperature with a high gas production rate. At the same time, the waste heat of the flue gas after the biogas combustion is not further utilized, resulting in heat loss, and does not involve waste heat heating of the soil layer and smoke.
