The invention provides a batch preparation method for a titanium-based air suction element with the high porosity. The preparation method comprises the following steps that under the condition of argon protection, titanium powder and a mixture of molybdenum powder, zirconium ferrovanadium powder, zirconium aluminum powder and zirconium nickel powder are evenly mixed, and a titanium-based raw material is obtained; under inert gas protection, the titanium-based raw material and ammonium bicarbonate are evenly mixed, an organic binder bond is added, and an injecting feedstock is formed; the feedstock is deposited on modified metal wires, subjected to forming through isostatic cool pressing and taken out after pressure relief and demoulding, and a blank is formed; under a vacuum state, the blank is stored in trichloro ethylene to be subjected to chemical degreasing treatment and then taken out for cooling, and a chemical degreasing blank is obtained; and the chemical degreasing blank is subjected to high-temperature sintering in a vacuum sintering furnace, cooled and taken out of the vacuum sintering furnace, and then the high-porosity titanium-based air suction element with the porosity being higher than 50% is obtained. According to the titanium-based air suction element with the high porosity, a preparation technique is simple and easy to operate, and the air suction element is high in porosity, good in manipulative performance and excellent in air suction performance.
