The manual main valve of liquid, the outlet end of the soda acid injector are equipped with concentration detector and connect with regenerating unit, and controller receives institute
The feedback signal for stating concentration detector controls the aperture of the pneumatic control valve.
Further, it is equipped between the outlet end of two feed flow branches and the soda acid inlet of soda acid injector pneumatic
Valve.
Further, batch meter import pneumatic operated valve is equipped between the first manual valve and the soda acid batch meter.
Further, the acid & alkali liquid import of the high-order storage soda acid tank is equipped with the first valve.
Further, the industrial water inlet of the high-order storage soda acid tank is equipped with the second valve.
General soda acid batch meter liquid level is about 1.5M, and storage is about 1 ton, and high-order 4-5 meters of 1 height of soda acid tank of storage,
Storage is about 20 tons, and static pressure is 2-3 times of soda acid batch meter, such as will lead to acid into soda acid mode according to the first feed flow branch
Alkali concentration is too high and controls difficulty.Therefore 1 hand-operated valve and a pneumatic control valve, adjustment acid are set in the second feed flow branch
When alkali concentration, the manual main valve of standard-sized sheet feed flow, crack second hand-operated valve, pneumatic control valve is according to the Concentration Testing after soda acid injector
The concentration of device detection, is automatically adjusted by controller, and acid base concentration is adjusted in a suitable range, then is controlled into acid
The alkali time can reach regenerated purpose.The second hand-operated valve can maintain aperture motionless after having regenerated, and it is manual only to close feed flow
Main valve, this mode can make acid base concentration maintain an ideal range always in practice, and regeneration effect is big
Width improves.
Compared with prior art, the utility model has the following beneficial effects: when soda acid batch meter is needed more by corrosion
When changing or repairing, first manual valve and batch meter outlet hand-operated valve need to be only closed, opens the second hand-operated valve, and certainly by controller
The dynamic aperture for adjusting pneumatic control valve, using the second feed flow branch feed flow, entire soda acid batch meter dismounting and change process is whole
A system is without shutting down, by manual, the pneumatic control valve that adjust the second feed flow branch road, it can guarantees the second feed flow branch
Feed flow feed flow concentration identical with the first feed flow branch guarantees stability when whole system regenerates into acid base concentration, is conducive to
Improve regeneration effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
