Your kitchen sink should already be vented if there is a p-trap draining to the wall. if it is an s-trap it is not vented and not to present code requirements. The dishwasher drain goes into the side of the disposal and the disposal should drain to the trap. A separate vent is not required for the disposal or dishwasher as the trap for the sink is what requires a vent.
