DETAILED DESCRIPTION - The method comprises forming superheated vapor in a boiler by mechanical atomization and impacting flow evaporation to catalyze dairy manure in hydrolysis treatment process, using smoke energy discharged by the boiler as fuel for drying the dairy manure, and using off-gas energy generated by catalyzing and hydrolysis treating process for drying the hydrolysis residues and acetate aqueous solution from cooled concentrated off-gas. The step of forming superheated vapor in the boiler comprises driving a nozzle to realize water atomization by compressing pump or hydrostatic method, where low temperature steam is formed, passing the low temperature steam into a lower drum of a boiler to generate kinetic energy, heating and dilating the low temperature steam entering in the lower drum, rising the steam to an upper drum through a convection tube, and finally passing into the superheater to generate superheated steam, which is used by the heating equipment through a divided air cylinder, a steam meter and a voltage regulator. The low temperature vapor has adjustable pressure, which is calculated by 0.1-0.6 coefficient of the highest pressure according to the set value of the boiler, and the pressure of atomization and evaporation is controlled by adjusting motor revolutions. The step of using smoke energy comprises passing the smoke generated by the boiler via a heat absorption section of a heat pipe exchanger to lower the temperature, then passing into a drying roller preheater, preheating the dairy manure, putting into dairy manure dryer, lowering the temperature of the smoke, discharging directly in the air after dedusting and desulfurating, blowing the smoke to a heat releasing section of the heat pipe exchanger connected with the heat absorption section by an air blower, drying the preheated dairy manure using the energy released by the heat releasing section, and briquetting the dried dairy manure to get manure fuel for the boiler. The step of using off-gas energy generated by catalyzing process comprises introducing acetic contented off-gas with certain temperature and pressure produced by catalyzing tank in the heat absorption section through a reducing valve, lowering the temperature, passing into the heat absorption section, condensating acetic acid and water in the off-gas, separating from the hot air to obtain acetic solution and taking the heat through the heat releasing section of the heat pipe exchanger as complement source of heating the acetic solution to evaporate and concentrate. The step of evaporation and concentration of the acetic solution comprises compressing and atomizing the acetic solution, spraying to the heat releasing section of the heat pipe exchanger by jet flow, absorbing the flashing steam and sending to the condenser by a draught fan, and cooling to condensate water for recycle. An atomization angle is 30-75 degrees C, and a jet velocity is 0.1-10 m per second during the compressing and atomizing process.
