The invention provides a safe low-energy-consumption forming method for a titanium-silicon molecular sieve spray. The method comprises the steps that an additive is added into hydro-thermal synthesized titanium-silicon molecular sieve crystallization liquid at first to enable the titanium-silicon molecular sieve crystallization liquid to be preclustered to a millimeter-sized cluster; organic matter such as most water and temple agent is separated out; the preclustered cluster is dispersed into an acid aqueous solution, spraying is carried out at the low inlet temperature and the high feeding speed to enable the cluster to achieve secondary dehydration so as to be clustered into micron-sized particles, roasting is carried out, and a spherical TS-1 catalyst is obtained. The problems that mixing is uneven and a spray head is blocked when raw powder spray is adopted are solved, and the potential safety hazard of organic matter carbonization or burning explosion caused when inlet and outlet temperature is too high during crystallization liquid concentration spraying is avoided.
