Abstract
The invention relates to a heat pump marsh gas tank, in particular to an air energy, solar energy and ground source heat pump marsh gas tank, which belongs to environment engineering equipment. The heat pump marsh gas tank consists of an anaerobic digestion system, a heat insulation and thermal preservation system, a solar energy hot water system, an air energy heat pump system, a ground source heat pump system and a control system, wherein the tail end heat exchange equipment of the ground source heat pump system, solar energy hot water pipelines and the air energy heat pump system are connected with the heat insulation and thermal preservation system and the anaerobic digestion system through hot water circulation pipes, a hot water transit box arranged in the thermal preservation system is used for regulating and balancing the hot water of heat resource systems, hot water heats the anaerobic digestion tank through circulation pipes for promoting the anaerobic digestion, and the hot water circulation pipes can be arranged inside the anaerobic digestion tank and can also be arranged outside the anaerobic digestion tank. The marsh gas tank can also provide hot water and cold air at the same time of producing marsh gas, and the invention can solve the problems of high production cost, great energy consumption and the like of winter production of the marsh gas engineering, and can be popularized easily.
Description
Technical field [0001] The invention relates to a heat pump biogas tank, in particular to an air energy, solar energy and ground source heat pump biogas tank. It is suitable for the comprehensive utilization of crop straw, kitchen garbage, livestock and poultry manure and sewage, etc. It is an equipment and device required for environmental engineering. Background technique [0002] Under the current situation of energy crisis, expanding the recycling of resources, promoting the scientific utilization of biomass energy and protecting the ecological environment have increasingly become the theme of today's world development. Biogas is the transformation of biomass energy into clean energy. The existing traditional biogas digesters include large and medium-sized biogas projects with high cost and low efficiency, and the treatment of manure is not thorough and fast. , electricity and other high-quality energy, high cost, is not conducive to the promotion of northern cold regi...
