Chemical industry circulating water system

With the development of industry and the needs of life, the amount of water has increased dramatically. Therefore, saving water has become a top priority. The use of circulating cooling water is an important way to save water resources. Moreover, circulating cooling water running at a high concentration multiple can also reduce environmental pollution. The chemical plant cooling circulating water treatment equipment exactly meets this situation. It not only saves water but also removes impurities from raw water. The degree of automation during the operation of the equipment is high and will not cause environmental pollution. And it is safe and reliable. Cooling water is used in industrial production, and the proportion of cooling water in production water is large. In the chemical plant, saving the amount of cooling water is the key to saving water, and it is also the focus of industrial enterprises to save water and energy. Due to the long-term use of cooling water, it can cause corrosion and scaling of the pipeline. To manage these problems in production, chemical plants need to use circulating water treatment equipment.


The cooling water system can be divided into DC cooling and circulating cooling. Cooling water must be recycled from the perspective of water conservation, rational use of energy and environmental protection. And it is necessary to achieve safe operation of high concentration ratio under the guidance of water treatment theory. In order to make the cooling water system operate safely, it is necessary to use the valve correctly and rationally to control the circulation of the medium between the pipes.


Bundor Valve, a high quality valve manufacturer, can provide you with a complete set of chemical plant circulating cooling water system valve solutions.

Valve for chemical circulating cooling water system

The cooling water system can be divided into DC cooling and circulating cooling (open system, closed system).

Open circulating cooling water system: One of the main equipment for an open circulating cooling water system is the cooling tower. There are many types of cooling towers, which can be divided into natural ventilation and mechanical ventilation according to the power of air flow in the tower. The most common type of natural ventilation is a ducted cooling tower. Mechanical ventilation is divided into exhaust and blast.

The main valves used in this system are: electric ventilation butterfly valve, electric soft sealing butterfly valve, PTFE lined butterfly valve, flange ball valve, stainless steel swing check valve, flange globe valve, cast iron gate valve, bellows expansion joint and so on.
