PIPE SYSTEM CLEANING AND IN-LINE TREATMENT OF SPENT CLEANING SOLUTION |
摘要 |
A mobile cleaning unit (50) is connected to a fouled pipe (60) to be cleaned. A pump (65) circulates cleaning solution from a reservoir (70) through an injection valve (80) in the mobile cleaning unit (50). The solution is regulated by diverter valves (85a, 85b) to an upstream valve (90), through the pipe (60), out a downstream valve (100), and through a return valve (110) to the reservoir (70). Treatment is monitored at either an upstream (115) or a downstream isolation valve (118). Spent solution is recirculated until it is environmentally safe for discharge out a drain valve (120). The process minimizes both the volume of treated spent solution and the treatment time. |
