The invention discloses a technique for rapidly extracting ramie hemp erwinia bacterium factory production fermentation, the technique comprises preprocessing material, immersing or sprinkling and inoculating, immersing or fermenting, deactivating with hot water, and the procedure of circulation washing, water dressing and fiber finish, erwinia bacterium which has broad-spectrum and high effective to degumming, pulping and saccharifying of herb fiber material, and bacterial agent preparation and activated technical parameter. The erwinia bacterium addicts the mannose, the peak for secreting non-cellulose to degrade key enzyme (pectic enzyme, beta-mannase and xylanase) can be achieved through purely culturing for 7h to 9h. Bacterial agent is inoculated on herb fiber material such as ramie and the like for activating the bacterial agent for 5h-6h, fermentation forage fodder turns to blue after fermenting for 5h-6h, pectine, hemicellulose and partial lignin which are partially degraded and associated in fiber cell are stripped, non-cellulose residues which are absorbed on fiber can be removed by means of the flushing of high-pressure flushing, and the purpose of extracting net fiber can be reached.

The invention discloses a CO2 decomposing method, a CO2 decomposing system and application thereof. The CO2 decomposing method includes: putting CO2 in a radiation range of a radiation source so as to utilize ionizing radiation to decompose CO2 into CO and O2. By the CO2 decomposing method, CO2 decomposition can be realized effectively to obtain CO and O2 having industrial application value; besides, devices or materials releasing ionizing radiation are fully utilized, waste recycling is realized and equivalent to zero energy consumption, cost is low, and efficiency is high.

The invention discloses an intermittent fluidization thermal energy and chemical energy storage and release reaction device and a working method. The device comprises a fluidization system, a heat exchange system and a gas-solid separation system. The fluidization system is located at the bottom of the reaction device. The heat exchange system is located in the middle of the reaction device. The gas-solid separation system is located at the top of the reaction device. The fluidization system is connected with the heat exchange system through an internal horizontal baffle. The heat exchange system is connected with the gas-solid separation system through a cyclone separator. The gas-solid separation system is connected with the fluidization system through an external material guide pipe. According to the intermittent fluidization thermal energy and chemical energy storage and release reaction device and the working method, a thermochemistry energy storage mode is adopted, and the thermal conversion efficiency is high; backmixing of reactants is reduced through an intermittent reaction; the reaction is more sufficient through secondary gas inlet; the energy storage process and the energy release process are conducted independently, and operation is easy; and the gas-solid separation system is arranged internally, so that the separated gas has the advantages of being purer and easy to recycle. The intermittent fluidization thermal energy and chemical energy storage and release reaction device and the working method can be used for occasions of solar-powered Rankine power generation or other large-scale thermal energy storage, and the thermal energy grade is improved.

The invention relates to a processing technology for driving gear hard cutting threading of a spiral bevel gear in a main decelerator for processing an automobile, the processing technology is characterized in that heat treatment on Phi 10-Phi 100 mm low carbon alloy steel base materials-carburization quenching-tempering-heat insulation for 2 hours at the temperature of 170 to 180 DEG C-annealing at the thread part at the temperature of 600 to 900 DEG C and the surface hardness of 28 HRC-43 HRC-dry cutting of thread, the rotating speed of work pieces at 500 to 900 circles per minute, the cutting speed at the 50 to 80 meters per minute-detection for warehousing. The invention has the advantages that the processing precision is high, the efficiency is high, the cost is low, the technological process is reduced, by adopting the dry cutting process, the cutting oil is not required, and the invention is pollution-free.
