how to separate NaNO2+KCl?

You meant NaNO3 not NO2.
I don't think this reaction is towards NaNO3 which is more soluble than KNO3, while KCl has similar solubility with NaCl. There's certainly a
balance, but I guess is a bit more to the left side of the reaction.

A better way is to buy cold packs from the pharmacy or Walmart. Make sure it contains NH4NO3. Mix with NaHCO3, add a little water and distill. You can
lead the NH3 vapors into water if you need ammonia solution.
The reaction is
NaHCO3 + NH4NO3 ---> NaNO3 + NH3 + H2O + CO2
The bad news is that most cold packs now have urea instead of NH4NO3.
