Specific embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
A kind of device for being used to quantitatively add tool bromine corrosion initiator, including batching kettle 1, balance pipe 2, reaction kettle 5 and determines
Measuring tank 3, quantitative pot 3 are equipped with holding vessel, feed inlet, pre-stored tank and discharge port, and feed inlet is connected by balance pipe 2 and batching kettle 1
It connects, balance pipe 1 is equipped with one 2-1 of valve, and discharge port is connected with reaction kettle 5 by pipeline, is set between pre-stored tank and holding vessel
There is control valve, the one side of control valve is equipped with counting device, uses counting device, the number of record control valve switch.It is fixed
Measuring tank is that material is stainless steel, and outside is equipped with glass scale, and outside is equipped with scale, stainless steel model 316L.One 2-1 bags of valve
Spool and valve rod are included, spool is equipped with the limbers of several inlet and outlet, and the outer end extended conduit of valve rod is equipped with handle,
Sealing ring is equipped between valve rod and pipeline, the maximum water flowing aperture of each limbers is of different sizes and when valve is in opening
When, only one limbers is in connection inlet and outlet state, can be accurately controlled the speed of charging.Pipeline
Dial is equipped between handle, dial is marked with several sections and represents that above-mentioned each limbers opens and closes the scale of degree respectively.
