Narrative:

The event occurred due to the anti-ice system having something wrong with it and not performing properly. During our approach into ZZZ to runway xxr we were in freezing drizzle and fog conditions and were being vectored onto final. I was pilot flying and we were asked to keep the speed up for a little bit which we did. I believe it was 210 kts. Then we got a wing anti-ice fail message and we followed the QRH and turned the system to all. Shortly thereafter; we got a red warning and bells for anti-ice inoperative in icing conditions. We quickly assessed the situation and neither I nor my first officer (first officer) could determine if we were accumulating ice on our critical surfaces; but we did have about 1 inch or more ice already on our windshield wipers. The QRH states to 'exit and avoid icing conditions'. The best; safest and only option we had in that moment was to get on the ground as quickly and as safely as possible. Simultaneously; ATC asked me slow down as they usually do at this point in the approach. My first officer and I both agreed that we could not comply. I asked him to [request priority handling] as we were in a moderate icing condition with possible anti-ice failure. We were already configured with flaps 9 at this point; so I kept our speed above 190 kts. To the final approach fix and then configured gear down & flaps 22 for our final setting according to the QRH. Due to our time constraints and being in such a critical phase of flight; I did not ask for my first officer to 'rebug my new speeds' of vref 45 +30kts per the QRH. We kept the speeds that were there in order to avoid a distraction and we flew the new speeds manually. We made a normal landing without any issues or need for any further assistance and taxied safely to our gate. This was simply an equipment issue that resulted in the emergency. I can only suggest continued good maintenance practices to ensure all systems are operating properly.
