The purification system should maintain positive pressure operation, as a result of all sorts of equipment and
pipeline gas purification system has certain resistance losses, so must be strictly controlled from half to the
net net main manifold pressure of each point.Half net main pressure control in < 10, 00 palmer, net manifold
pressure should be controlled in > 200 mpa.In half 800 net manager, while the net manifold pressure generally
can reach 400 ~ 600 mpa, depending on whether there is a washing tower packing, size and gas flow and decide,
when washing tower packing, the more the greater is the resistance loss, net manager will reduce stress, when
the greater the flow, the gas velocity, the pressure will reduce net manager.
Overpressure operation, namely the purification system has been in more than 1000 mpa pressure operation is not
allowed, because in the purification system
High pressure run, leakage phenomenon will seriously, tar and water seal and seal sometimes due to the sudden
pressure system. Running water seal gas phenomenon.If there is high pressure running, the water seal point
must be designed according to the requirements of specification.
Low voltage operation is not safe, because if the net manager at negative pressure, so there may be air leakage
into the gas pipeline, it's not safe in a row to send machine running, if electrical tar instrument result until
the negative pressure, the inhaled air is extremely easy to produce explosion phenomenon. |
