For such a critical ruling you should consult a Mufti to give you the correct verdict taking into account all the relevant details ... for example the wording and the intention plays a part.
According to the Hanafis, and AFFAIK most of the classical scholars ... three divorces in a single go are effective and come into force.
From the Hanafi text Hidayah (view here):
Talaq al-bidah (innovation conflicting with the Sunnah) is that he divorce her with three repudiations pronounced in a single
statement or three repudiations in a single period of purity. If he
does this, the divorce takes effect, but he has sinned. Al-Shafi`i
(God bless him) said that each form of divorce is mubah (permissible)
as it is a legally valid act so that it leads to its legal effects.
From the Hanafi Tafsir Ahkamul Quran by Abu Bakr Al-Jassas (view arabic here):
قوله (تعالى): الطلاق مرتان فإمساك بمعروف أو تسريح بإحسان ؛ الآية؛ يدل
على وقوع الثلاث معا؛ مع كونه منهيا عنه؛
[my translation] The verse 2:229 " لطَّلَاقُ مَرَّتَانِ ۖ فَإِمْسَاكٌ بِمَعْرُوفٍ
أَوْ تَسْرِيحٌ بِإِحْسَانٍ " gives proof for the validity and enforcement of three
divorces given together.
From Tafsir Qurtubi (Maliki scholar, but mentions the majority view and doesn't mention a dissent for the Hanafis):
قال علماؤنا: وٱتفق أئمة الفتوى على لزوم إيقاع الطلاق الثلاث في كلمة
واحدة؛ وهو قول جمهور السلف، وشذّ طاوس وبعض أهل الظاهر إلى أن طلاق
الثلاث في كلمة واحدة يقع واحدة
[my translation] Our Ulema say: The Imams of Fatwah are agreed on the matter that
giving three divorces in one statement makes them binding and this is
the saying of the majority of the Salaf. And Tawus and some of the Ahl-e-Zahir
said that giving three together enforces one divorce.
Also see islamweb:
However, if one delivers three divorces at once by saying an
expression such as: "You are divorced thrice", without repeating the
expression (I divorce you), then the Muslim Scholars differed in this
case. Imams Abu Haneefah, Malik, Shafi’i, Ahmad and the majority of
the Muslim Scholars consider this kind of divorce as divorcing three
However, Imam Tawoos, Ibn Taymiyah and other contemporary Scholars
consider it as only one divorce.
Regarding the state of anger, it does not effect the divorce unless the anger was of such an extreme nature that it reached lunacy, see Radd al Muhtar, and the approximate translation here, again this is something you should elaborate to a Mufti and he will guide you further.
