After having fed, add entrance (6) by described housing corrosion inhibiter and add corrosion inhibiter；
(d) by acid-adding port (5) add nitre acid for adjusting pH value, be analyzed to identify qualified after, by carbamide ammonium nitrate
Solution exports (18) introducing delivery pump by described carbamide ammonium nitrate solution and sends.
10. the user of the special equipment of the industrial producing urea ammonium nitrate solution described in claim 2 or 8 any one
Method, it is characterised in that: comprise the following steps:
A () first passes through urea liquid import (1) and adds liquid area, being determined by urea level meter is needed
The carbamide proportional quantity wanted；
B described in () step (a), liquid area has fed after, by described ammonium nitrate solution import (2)
Add liquid ammonium nitrate, by carbamide ammonium nitrate liquidometer gauge height, determine the ammonium nitrate proportional quantity of needs；
C in () step (b), liquid ammonium nitrate adds, rear turn on agitator and cooler, and corrosion inhibiter adds entrance (6)
Add corrosion inhibiter, add nitre acid for adjusting pH value by acid-adding port (5), observe carbamide ammonium nitrate solution temperature,
Variable density, analytical sampling, qualified after send.
