Biomass energy generation device suitable for use in cold region.

Abstract

The invention provides a biomass energy generation device suitable for use in a cold region. Wastes are pretreated in a pretreatment pond (11), liquid to be treated after pretreatment is divided into two gushes through a pump (9), wherein, one gush can be directly introduced into a water mixing valve (7), and the other gush is introduced into the water mixing valve and mixed with cold water after heated by a heating system, a control system keeps track of the temperature of cold and hot water so as to regulate the flow rate of the cold and hot water, so that the liquid to be reacted in the water mixing valve can maintain at constant temperature, and the liquid to be treated is introduced into a main reactor (1) for reacting; after reaction, sewage is introduced into an aerobic treating pond (12), the sewage is treated and the clean water is introduced back into the pretreatment pond, the gas from the main reactor (1) enters into a methane air storage chamber (14). The biomass production capacity device of the invention can effectively treat solid waste, can generate biogas and hydrogen at the same time, and effectively reduces energy consumption, so as to realize waste water cycling and cycle operation in four seasons systematically.

Description

(1) Technical field [0001] The invention relates to a waste water treatment and energy generation device. Specifically, it is a renewable energy development cycle system with anaerobic biological treatment technology and biological fermentation technology as the core, adding energy-saving methods such as waste heat utilization. (2) Background technology [0002] Due to the cold and long winter in the north, the air temperature and ground temperature are low, the decomposition rate of raw materials is low, and the fermentation production has problems such as low gas production rate, low utilization rate, and poor comprehensive benefits. This situation limits the biomass energy utilization technology in cold regions to a certain extent. development of. (3) Contents of the invention [0003] The purpose of the present invention is to provide a kind of suitable for the cold area in the north that can efficiently process solid waste, and can generate biogas and hydrogen at the...
