Circulating water intelligent adjusting device

Abstract

A circulating water intelligent adjusting device comprises a valve body, a self-operated temperature control part, an automatic pulsating flow washing part and a cut-off part. By means of the circulating water intelligent adjusting device, the production cost can be lowered on the premise that the functions of the circulating water system are achieved, and the descaling function and the cut-off function are achieved. The circulating water intelligent adjusting device can play the water-saving effect; the pulsating flow washing part can generate pulsating flow, and thus the dirt growth speed of a pipeline can be effectively decreased; the cut-off part can achieve the flow cut-off function, and therefore field replacement is easy.

Description

technical field [0001] The invention relates to an intelligent regulating device for circulating water. Background technique [0002] Heat exchange processes exist widely in petroleum and chemical production processes, such as equipment cooling, process medium cooling, and waste heat recovery, etc., and heat exchange equipment and various adjustment systems are necessary conditions to ensure the smooth progress of heat exchange processes. In the production process of petroleum and chemical products, circulating water is mainly used to cool various high-temperature process media. Since the cooling water temperature fluctuates greatly due to the influence of the external environment, the maximum temperature difference can reach about 30 degrees Celsius. If the cooling water flow rate remains constant, it will directly lead to excessive cooling water consumption, resulting in a huge waste of water resources and a significant increase in sewage discharge. [0003] At present, a...

Problems solved by technology

Because the cooling water temperature fluctuates greatly due to the influence of the external environment, the maximum temperature difference can reach about 30 degrees Celsius. If the cooling water flow rate remains constant, it will directly lead to excessive cooling water consumption, resulting in a huge waste of water resources and a significant increase in sewage discharge

[0003] At present, although there are a large number of similar self-operated temperature control devices on the market, none of them can be widely used in the intelligent regulation of circulating water.

On the one hand, there are few models of existing self-operated temperature control devices, which are mainly used for flow control devices with specific process conditions. They are expensive, the cost of transformation is too high, and they have poor adaptability to industrial sites, and cannot meet the requirements of flow, temperature, size, etc. Requirements for various changes; on the other hand, the existing self-operated temperature control device is only used for flow regulation, and does not consider the disadvantages of excessive scale growth caused by the reduction of industrial water flow, which further affects the heat transfer efficiency

[0004] To sum up, the existing self-operated temperature control devices on the market are relatively expensive, have poor adaptability, cannot be widely used in intelligent regulation of circulating water, and do not have the washing function to prevent scaling
