Flocculant dosing device is commonly used in oil field. Flocculant can make the dispersed fine-grained solid in the liquid form polymer of flocculate, and the use effect can be better achieved through the device.

Structure principle of flocculant dosing device:

Flocculant dosing device is mainly composed of solution tank, mixing tank (with mixer), metering pump, liquid level gauge, electric control cabinet, pipeline, valve, safety valve, check valve, pressure gauge, filter, base, ladder, etc. (it can be configured according to the actual requirements of users).

The flocculant dosing device is prepared in the mixing tank according to the required reagent concentration. After being evenly stirred by the mixer, it is put into the solution tank, and the prepared solution is delivered to the dosing point or the designated system by the metering pump (dosing pump). The whole set of dosing device has the characteristics of compact structure, simple safety and easy operation. The device can also be designed and equipped with necessary components according to the requirements of different technological processes of users, so as to realize functions suitable (such as automatic remote control), economical and practical.

The theoretical basis of flocculant dosing device is "coalescence" theory. Flocculants are mainly positive (negative) genes and some particles or particles with negative (positive) electricity in water that are difficult to separate, so as to reduce their potential and make them in an unstable state, and use their polymerization properties to make these particles concentrated and separated by physical or chemical methods. Flocculant is mainly used in the field of water supply and sewage treatment. The treated sewage can basically meet the discharge standards in terms of chroma, chromium content and suspended matter content, and can be discharged or used as reinjection water for artificial water injection and oil recovery.

Characteristics of flocculant dosing device:

Flocculant dosing device is an intelligent, automatic and continuous integrated flocculant dissolving and dosing device. The flocculant preparation device is suitable for the preparation and dosing of polymer organic flocculant. Users only need to directly add the dry powder into the hopper of the equipment to realize the full-automatic feeding, dissolution, aging, storage, metering and dosing process. The whole process does not need human operation, and is fully automatic.

Application of flocculant dosing device:

1. Dissolving, mixing and adding of coagulant, coagulant aid, disinfectant, bleaching agent, polyelectrolyte, lime slurry and other solutions in water engineering.

2. Configuration and dosing of various acid and alkali solutions.

3. Configuration and dosing of regeneration liquid in softening and desalting water treatment.

4. Configuration and dosing of stabilizer for circulating cooling water quality.

5. Addition and preparation of various industrial additives.
