That is a twin/tandem/skinny breaker, not a two-pole breaker. That breaker will NOT give you 240v. It will give you two 120v circuits.
You need TWO spaces for a 240v circuit.

IF, and only if, your panel will accept twin breakers you can use one to free up a space in your panel by consolidating two 120v circuits to one space. Even this has risks so be sure you know what you are doing first.

Also, what size circuit do you need? "220" means nothing without more info.

The circuit you need will be 240v at a certain amperage. The amperage is the size of the circuit.
