Try something like these

Select 
replace(replace(name, CHAR(13), ''), CHAR(10), '')
from 
Table1

Open in new window

This one removes all these:
Tab -> char(9)
Line feed -> char(10)
Carriage return -> char(13)

Select 
replace(replace(replace(name, CHAR(13), ''), CHAR(10), ''),char(9),'')
from 
Table1

Open in new window

You need to use RemoveSpecialChars  function in your query like

select dbo.RemoveSpecialChars(Name) AS Name from Table1
