Energy-saving organic waste anaerobic composting reaction device with adjustment function

Abstract

The invention relates to an energy-saving organic waste anaerobic composting reaction device with an adjustment function. The energy-saving organic waste anaerobic composting reaction device comprisesa heat preservation room and two cover plates. A support mechanism, a support plate, a treater, a reaction mechanism and two support rods are arranged in the heat preservation room. The support mechanism comprises a first motor and two support assemblies. The support assembly comprises a driving unit, an extension frame, a hinge block and two connecting rods. The reaction mechanism comprises a reaction tank, a first sealing plate, a gas outlet pipe and a feeding mechanism. The support mechanism drives the support plate to move so that the reaction tank can enter or leave the heat preservationroom according to the external environment temperature, the energy consumption required for maintaining the temperature of the reaction tank is reduced and the energy saving effect is realized. An alkaline agent is added into the reaction tank through the feeding mechanism so that the composting reaction occurs in the appropriate neutral environment, anaerobic composting is promoted and the device practicality is improved.

Description

technical field [0001] The invention relates to the field of organic waste resource treatment equipment, in particular to an energy-saving organic waste anaerobic composting reaction device with regulating function. Background technique [0002] Organic waste, also known as wet waste, refers to waste containing organic components in domestic waste. More than 50% of municipal solid waste is organic waste, and it is increasing year by year. Anaerobic composting technology can effectively realize the reduction, harmlessness and recycling of organic waste, and it is a waste treatment technology with broad prospects. Anaerobic composting means that organic waste is stabilized and fermented by microbial metabolic activities under anaerobic conditions, accompanied by the production of methane and carbon dioxide. [0003] However, in the initial stage of operation of the existing anaerobic composting reactor, a large amount of organic acids will be produced in the tank, so that th...

Problems solved by technology

[0003] However, in the initial stage of operation of the existing anaerobic composting reactor, a large amount of organic acids will be produced in the tank, so that the pH value of the material will drop below 5, and the anaerobic fermentation bacteria can maintain an active state in a neutral environment, so , with the production of a large amount of organic acids, it will inhibit the fermentation process, resulting in a significant reduction in the reaction rate. Not only that, anaerobic fermentation needs to maintain a suitable temperature environment, and the appropriate reaction temperature in the tank can be maintained by sunlight during the day. But at night, due to the loss of light, the temperature in the tank decreases. At this time, in order to keep the anaerobic fermentation, it is usually necessary to consume a large amount of energy to maintain the temperature in the reaction tank, which leads to the great practicability of the existing anaerobic composting reactor.
