Aerobic pressurizing high-temperature fermentation tank for solid organic matter

Abstract

The invention discloses an aerobic pressurizing high-temperature fermentation tank for solid organic matter. The aerobic pressurizing high-temperature fermentation tank for the soil organic matter comprises a tank body, a feeding system, a fixed shaft, a distributing mechanism, moving mechanisms, a discharging mechanism, a gas discharging port, outlets and internal heat exchangers. The feeding system is arranged at the top of the tank body, the fixed shaft is arranged inside the tank body and is of a hollow structure, the two ends of the fixed shaft are connected with the top and the bottom of the tank body respectively through bearings, and the bottom end of the fixed shaft is sealed and extends out of the bottom of the tank body to be connected with a hydraulic motor; the distributing mechanism, the moving mechanisms and the discharging mechanism are sequentially arranged on the fixed shaft from top to bottom; the gas discharging port is formed in the top of the tank body, the outlets are formed in the bottom of the tank body, the internal heat exchangers are arranged on the inner wall of the tank body, gas inlets are connected with an oxygenating pressurizing system, and gas outlets are connected with the top end of the fixed shaft. Oxygen needed for fermentation is guaranteed through the fermentation tank, the two sets of internal and external heat exchangers can effectively utilize temperature generated by biological fermentation, stable fermentation temperature is guaranteed, temperature rises rapidly, composting and harmlessness are faster and more complete, water evaporates rapidly through differential pressure control, the fermentation period is shortened, and efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fermentation tanks, in particular to an aerobic pressurized high-temperature fermentation tank for solid organic matter. [0002] technical background [0003] At present, my country's high-efficiency and intensive agriculture and agricultural product processing industry have achieved rapid development, which has also brought a large amount of solid organic resources to be idled and discarded, resulting in waste of organic resources and environmental pollution in many places. Solid organic matter includes straw, Chinese herbal medicine dregs, cassava dregs, bagasse, livestock and poultry dung, press-filtered bacteria sludge, etc. After pretreatment such as crushing, biotechnology can be used to convert it into It is rich in humic acid and nutrient products that animals and plants can absorb. It returns to modern agricultural production and reduces the use of chemical fertilizers in agricultural production....

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an aerobic pressurized high-temperature fermenter for solid organic matter, which solves the problem of large area occupation, difficulty in waste gas treatment, difficulty in controlling fermentation temperature and process, slow water evaporation, long fermentation cycle, and collection and transportation costs in traditional methods. The problem of high cost is to realize the equipment of the system, and the solid organic matter can be utilized as a resource on the spot, which is conducive to the popularization and application of technology and equipment
