Description
Technical field
The present invention relates to the medicament adding apparatus and adding method thereof of a kind of operation corrosion control of direct air cooled condenser, realize
To the control action of direct air cooled condenser operation corrosion.
Background technique
China put into operation Direct Air-cooled Unit direct air cooled condenser generally existing operational process corrosion the case where, at present
Corrosion product is mainly removed using equipment filter types such as deironing filter and ferromagnetic deironing devices.It can only be by being added in steam discharge
The mode of protection medicament can be only achieved the purpose for reducing direct air cooled condenser corrosion, as application No. is 201310193927.7
Chinese patent.But Direct Air-cooled Unit is not designed with the device and pipeline of steam discharge dosing, needs separately to consider how protective agent
It is added in steam discharge, and ensures that medicament can be evenly distributed in water-steam system, each position of direct air cooled condenser is corroded
All it can be effectively controlled.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide a kind of direct air cooled condenser
The medicament adding apparatus and adding method thereof for running corrosion control are incited somebody to action to realize the corrosion control to direct air cooled condenser
Protection medicament is added in the gland steam exhauster of direct air cooled condenser, and reaches the mesh that protection medicament is evenly distributed to water-steam system
, it is ensured that the general corrosion control effect of direct air cooled condenser.
Technical solution used by the present invention solves the above problems is: a kind of direct air cooled condenser operation corrosion control
Medicament adding apparatus, characterized in that add including explosive box, metering pump, medicament atomizer, No.1 chemical feeding points switching valve, No. two
Snack made with traditional Chinese medicines switching valve and medicine-chest isolating valve；The connection of one end of the explosive box and dosing pipe, and medicine is provided on dosing pipe
The other end of case isolating valve and metering pump, the dosing pipe is connect with 3-5 root medicament distribution pipe, the medicament distribution pipe connection
To direct air cooled condenser blow-off line, in medicament distribution pipe and in the external peace of direct air cooled condenser blow-off line
Equipped with No.1 chemical feeding points switching valve and No. two chemical feeding points switching valves, in medicament distribution pipe and in direct air cooled condenser steam discharge
The inside of pipeline is equipped with medicament atomizer.
Further, the medicament distribution pipe is arranged in parallel, and a medicament atomization is mounted in every medicament distribution pipe
Nozzle.
The adding method thereof of the medicament adding apparatus of the direct air cooled condenser operation corrosion control, characterized in that mistake
Journey is as follows: after preparing protection medicament in explosive box, opening the No.1 dosing in medicine-chest isolating valve and a medicament distribution pipe
Point switching valve and No. two chemical feeding points switching valves, starting metering pump will protect medicament addition Direct Air-Cooled to coagulate by medicament atomizer
In vapour device blow-off line；Then by successively opening or closing No.1 chemical feeding points switching valve in other medicament distribution pipes and No. two
Chemical feeding points switching valve increases or decreases the additional amount of protection medicament.
Compared with prior art, the present invention having the following advantages that and effect: in every blow-off line of direct air cooled condenser
An atomizer is arranged in pipeline, meets medicament in Direct Air-Cooled condensing for 3 ~ 5 chemical feeding points of upper setting, each chemical feeding points
Being uniformly distributed in device guarantees corrosion control effect.The dosage that valve regulation difference chemical feeding points can be switched by chemical feeding points, meets
The needs of dosage variation.
