0.001PPm, the filtering accuracy of fore filter 12 are 1um, the filtering accuracy of post-filter 13 is 0.1um.
Described oil expeller 11, fore filter 12, post-filter 13, air cushioning tank 16 and nitrogen storage tank 51,
Its bottom is equipped with blowoff valve.
Modularization is in order to realize some function, in the dissimilarity to a range of difference in functionality or identical function
On the basis of energy, the product of different size carry out functional analysis, divide and design some row functional modules, pass through the choosing of module
The function of final demand can be reached by selecting and combining, and meet technical need, and its final principle is to make every effort to form with a small number of modules
Whole system equipment, and make on the basis of meeting to require Product Precision is higher, performance is more stable, structure is simpler, layout more
Rationally, space is smaller, transport is more convenient and the connection of intermodule is as simple as possible, the requirement easily manipulated.
The present invention is according to main boiler on board using " nitrogen aerating phase corrosion inhibitor dry preservation method " demand during long-acting maintenance, is carried out
A kind of integral modular nitrogen charging maintenance system design.Such a nitrogen charging maintenance system can produce nitrogen and the progress of maintenance processed
Storage, realize monitoring and the automatic filling of boiler pressure.
