[0002] Water shortage is one of the problems faced by the world, and water conservation has become the consensus of mankind. Therefore, the promotion of circulating water cooling system in the industrial field has great significance for water conservation, and in the industrial circulating cooling water system, cooling water is continuously recycled,

[0003] The quality of water will deteriorate, causing corrosion and fouling of equipment, and in severe cases, it will damage the safety production of factory. Therefore, water quality must be monitored in time, and effective descaling and corrosion prevention treatment must be taken. The commonly used method for scale inhibition and corrosion prevention treatment is to use corrosion and scale inhibition composite agent, so the effect of the agent must be tracked in time.

[0004] At present, most of the cooling circulating water systems monitor the corrosion, fouling and deposition on the metal surface by monitoring the heat exchanger. Due to various reasons in the monitoring process, the fouling thermal resistance value is sometimes not accurate, which leads to the fact that the fouling of the experimental tube cannot be observed in time, and active measures cannot be taken effectively, and the final evaluation is also to take out the experimental tube stage, and the effect of water treatment is evaluated by weight loss method.

Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0025] In the description of the utility model, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0026] As Figure 1As shown, the embodiment of the present application provides a full-intelligent monitoring heat exchanger with pressure drop measurement, which comprises a simulation experiment pipe unit and an intelligent instrument unit. The simulation experiment pipe unit is configured with a long strip-shaped experiment pipe, the two ends of the experiment pipe are connected with a circulating water inlet pipeline and a circulating water outlet pipeline with adjustable flow, and the upper and lower sides of the pipe wall are connected with a steam pipeline and a condensing pipeline, respectively. The intelligent instrument unit is configured with a temperature measuring instrument for measuring the inlet water temperature, outlet water temperature and steam temperature of the experiment pipe, respectively, and a pressure difference instrument for measuring the pressure drop between the inlet and outlet of the two ends of the experiment pipe.

[0027] In the embodiment, the temperature measuring instrument comprises a thermometer and a temperature sensor, which are respectively arranged at the inlet and outlet of the two ends of the experiment pipe and the communication inlet of the steam pipeline and the experiment pipe. By arranging the thermometer and the temperature sensor at the inlet, the outlet of the experiment pipe and the communication inlet of the steam pipeline and the experiment pipe, the temperature at different positions can be accurately measured, and the temperature change in the heat exchange process can be comprehensively mastered.

[0028] For example, in an industrial circulating cooling water system, accurate temperature data is crucial for judging the heat exchange effect. If the inlet water temperature of the experiment pipe is high and the outlet water temperature drops significantly, it indicates that the heat exchange effect is good. On the contrary, if the outlet water temperature does not drop significantly, it may indicate that there is a problem such as fouling in the heat exchanger, which affects heat transfer.

When the system needs to be flushed or the flow needs to be adjusted, the manual valve and the manual flowmeter can be conveniently operated.

[0034] The steam pipeline is provided with a stop valve Q1, a flange Z4, a filter Q2, a pressure gauge Q3, a self-operated steam regulating valve Q4 and an electric regulating valve Q5, and a ball valve Q6 connected in series.

The pressure gauge is used to monitor the steam pressure in real time, the self-operated steam regulating valve can automatically adjust the steam flow according to the change of the steam pressure, and the electric regulating valve can realize more accurate steam flow control. Under the premise of ensuring the safety of steam supply, the steam flow can be efficiently adjusted to meet the steam demand of the heat exchanger under different working conditions.

[0037] In this embodiment, the full-intelligent monitoring heat exchanger further comprises an execution control unit connected with the electric regulating valve signal control and connected with the temperature sensor and the like signals to obtain relevant parameter data in real time.
