Working principle of circulating water flocculant preparation system

 

Introduction:

The fully automatic dosing device is mainly composed of solution tank, mixer, metering pump, Y-type filter, safety valve, back pressure valve, check valve, pulse damper, water level gauge, pressure gauge, control cabinet, and installation platform, which are installed on a base. Users only need to place the combined dosing device in the dosing room, connect the dosing pipe to the power supply, and then start and put it into operation. During the operation, automatically detect the pH of the fluid, intelligently judge and add the corresponding solution. This factory integrated device can greatly reduce the workload of design and on-site construction, basically realize unattended, and provide reliable guarantee for the quality, safety and on-site operation of the whole machine.

Application:

Full-automatic dosing device is used for the treatment of water supply, boiler water, circulating water, waste water, etc. in power plants, as well as in petroleum, chemical, environmental protection, water supply system and other industries.

characteristic:

1. Complete automatic protection measures ensure stable and safe operation of the system;

2. High degree of automation, uniform and accurate dosing. The dosage is controlled by the microcomputer dosing controller (metering pump), which saves a lot of manpower without any manual operation in addition to regular dosing into the dissolving barrel;

3. The whole process monitors the water quality of the system and controls the sewage automatically;

4. Various configurations are available for different water treatment users;

5. Through the unique preset program, the dosage is controlled to ensure the effect of dosing, and the dosage is limited;

6. Full-automatic continuous dosing technology ensures the timely and stable dosing and control of various chemicals.

Basic information of dosing device:

1. The dosing device is configured with various solid and liquid chemical solutions through different process designs, and then accurately added with metering pump to meet various design requirements. Such as scale removal, oxygen removal, coagulation, acid addition, alkali addition, etc.

2. The dosing process can be operated manually, and the dosing device can be turned into an electromechanical integration product through various electrical appliances and instruments such as PC, magnetic flap level gauge, PH meter, travel controller, frequency converter, etc. to realize automatic control.

3. The dosing volume and pressure of the dosing device can be selected according to the needs of the industrial process. Suitable products can be selected from the range of flow from 1 L/h to 8000 L/h and pressure from 0.1 MPa to 25 MPa.

4. The volume of the solution tank in the dosing device can be from 0.1m3 to 20m3, which can be selected according to the dosage. According to the different transmission media, there are a variety of materials to choose from, such as carbon steel (carbon steel rubber lining), stainless steel, non-metallic materials (PE, PVC, PP, PTFE), etc. The complete set of equipment mainly includes the feeding system, the storage tank, the dosing system, the power control system, etc.

Working principle of circulating water dosing device:

The circulating water system has problems of scaling, corrosion, biological adhesion and biological sludge accumulation. The cooling water is continuously recycled in the circulation. Due to the rise of water temperature, the change of water flow speed, the evaporation of water, the concentration of various inorganic ions and organic substances, the cooling tower and the cold water pool are exposed to sunlight outside, wind and rain, the entry of sundries, and the comprehensive effect of various factors such as equipment structure and materials, serious sediment adhesion will occur, Equipment corrosion and a large number of microorganisms and the resulting biological slime and other problems. The water flow resistance of the heat exchange equipment is increased, the power consumption of the water pump is increased, the heat transfer efficiency is reduced, and the production process conditions are in an abnormal state. Therefore, it is required to comprehensively deal with the above problems during the use of cooling water to ensure the normal and safe operation of the cooling system.

The concentration control technology of the dosing device is a control system that can be widely used in various complex water systems. Using this technology can continuously monitor the concentration of the water treatment agent in the system and automatically and accurately add the agent. Using the automatic dosing device technology can bring many benefits to customers.
