Dosing device use:
Dosing device is all air flotation and other sewage treatment process of a necessary device, it is a set of dosing, mixing, storage, delivery of liquid medicine, automatic control, integrated equipment. It is widely used in printing and dyeing, textile, slaughtering, papermaking, petroleum, tanning, chemical industry, paint, food, algae-containing surface water, coking, low temperature and low turbidity surface water, papermaking wastewater treatment and fiber recovery, biological treatment of sludge, water separation, electroplating and other wastewater containing heavy metal ions treatment, solid and liquid separation of many other wastewater. Such as the addition of NaOH sodium hydroxide (which regulates PH to neutral 6.5-8.5 when the PH of the raw water is below 6.5) and H2SO4 sulphuric acid (which regulates PH to neutral 6.5-8.5 when the PH of the raw water is above 8.5) , when the PH value of the treated raw water is between 6.5 and 8.5, adding proper amount of PAC (flocculant) and Pam (coagulant aid) to make the air floatation achieve the desired treatment effect.
Working structure principle:
The dosing device is mainly composed of a medicine storage box, a mixing tank, a mixer, a dosing pump (metering pump) , a flowmeter, an electric control cabinet, a pipeline, a valve, a check valve, an equipment underframe, an operating platform and an escalator, etc. . The dosing device is prepared in a mixing tank according to the required concentration of the medicine. The medicine is put into a medicine storage box after being stirred evenly by the mixer. The complete set of dosing device has the characteristics of compact structure, simple safety and easy operation. The device can also be designed according to the requirements of different technological processes of users, to achieve functions suitable (such as automatic remote control) , economic and practical.
3-1. The equipment structure is exquisite, the area is small, the installation and debugging are convenient. Three-two. Equipment supporting the use of domestic advanced components, long service life. Three-three. The main body of the equipment is made of corrosion-resistant and high-quality material, which is economical and durable. Three-four. Advanced control system, continuous operation of equipment, stability, safety.
Four. Type selection considerations:
4-1. When the user selects the dosing device, first of all, according to the system needs to add the amount of solution to determine the selection specifications (including dosing pump storage tank volume, mixing tank volume, and field conditions) , and then according to the situation, determine the input method (generally using"One with one ready" method) .
Four-two. Choose the material (stainless steel, carbon steel, glass fiber reinforced plastic) of each part of dosing device, the type of dosing pump (metering pump) or provide the parameters of dosing (such as name, concentration, temperature, density, viscosity, corrosivity, etc.) to our company. Four-three. Users according to the design process for the special requirements of dosing device.
