Design key points of dosing device and system in circulating water treatment

 

Industrial circulating water treatment is one of the important measures to ensure the normal production of the plant, and the dosing of chemicals is the lifeblood of industrial circulating water treatment. It is one of the topics that many design institutes and dosing device manufacturers are studying at present to add chemicals reasonably to achieve the effect and eliminate waste. In this paper, we will learn the design points of the dosing device and system in the circulating water treatment from the perspective of the dosing device manufacturer, so as to help the owner better design the circulating water treatment system and purchase appropriate dosing devices.

In the treatment of industrial circulating water, there is a saying that "medicament is the core, and dosing is the means". The design of reasonable dosing system and reliable dosing device is the basis for scientific dosing, rational dosing, eliminating waste and ensuring the treatment effect. In the current design of circulating water treatment dosing system, it includes the selection of dosing device, dosing pipeline and dosing point. If you want to achieve the desired effect, you have to consider whether the type of dosing device is appropriate?, Is the design of equipment room and dosing point reasonable? Only after these problems are clarified can the final water treatment results meet our expectations to the greatest extent. Now, let's enter today's topic and learn the design essentials of dosing device and system in circulating water treatment.

Design key points of dosing device and system in circulating water treatment

Selection of dosing device

At present, the common dosing devices on the market can be divided into two types in form: one is integrated dosing device, and the other is split dosing device.

Advantages of each dosing device:

The advantages of the integrated dosing device are that the equipment is highly integrated, the structure is compact, the floor area is small, and the maintenance is simple and convenient;

The advantages of the split dosing device are low technical threshold and low investment and construction cost.

Disadvantages of each dosing device:

The disadvantage of integrated dosing device is that the dosing cost is high, and the failure rate caused by high integration will increase;

The disadvantage of the split dosing device is that it occupies a large area.

In the design of circulating water dosing system, these two different forms have their own advantages and disadvantages. In the design of circulating water treatment dosing system, consideration should be given to their own needs and costs.

Pipeline layout of dosing room:

The pipeline layout also plays an important role in the whole dosing system. A reasonably designed pipeline can not only reduce the investment cost, but also improve the dosing effect.

Pay attention to the route of the pipeline in the pipeline design. It shall be determined according to the relative position relationship between the dosing room and each circulating water system pool to be dosed, and it shall be ensured that the dosing pipeline is connected to the dosing point with the shortest path. When the dosing pipeline crosses the roads in the plant area, generally no ditches are set. Steel casing can be embedded under the road first. The dosing pipeline is set in the casing to cross the road. Inspection wells should be set at both ends of the casing.

Summary:

In order to improve the circulating rate of industrial circulating water, improve the circulating water quality and reduce the environmental pollution of enterprises, it is essential to design a reasonable and scientific dosing system. For systematic design and creation, designers and users can grasp all aspects of the design from point to surface, from details to the whole, so that they can simply design the dosing system applicable to this project. As the manufacturer of the dosing device, Hechuang Environmental Protection can customize and process various non-standard circulating water dosing devices according to the project design requirements, and cooperate with other equipment in the system to achieve customer satisfaction.
