Embodiment Construction

[0051] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0052] figure 1 A schematic diagram of the principle of the heating pipeline leak point detection system is shown.

[0053] The system includes three parts: heat source, pipe network and users, and the heat supply pipe network includes water supply pipe network and return water pipe network. figure 1 Shown in is only the water supply pipe network (the return water pipe network is arranged symmetrically). The system divides the heating pipe network into two areas through the partition flow meter II (one for the supply and one for the return water pipe), and the online monitoring system of the pipe network reads the pressure, flow rate and The data of the par...

Abstract

The invention provides a town central heating system and a leakage point detection method. The system comprises a heat source, a heat supply pipe network and the users, the heat supply pipe network comprises a water supply pipe network and a water return pipe network, the system partitions the heat supply pipe network through partition flowmeters, and the pipe network online monitoring system reads the pressure and the flow of a heat source and a user and the data of the partition flowmeters according to a set fixed time interval, stores the pressure and the flow in a database in real time, and calculates the cumulative sum of the flow differences of inlets and outlets of partitions. According to the system and the method, the leakage point detection precision is greatly improved, and the timely and accurate diagnosis and positioning of the leakage fault of the urban central heating pipe network are realized.

Description

technical field [0001] The invention relates to a heat supply system, in particular to the technical field of intelligently detecting leakage points of a heat supply pipe network. Background technique [0002] The leakage of central heating pipe network will directly lead to the loss of a large amount of high-temperature medium in the pipe, thermally pollute the environment, serious leakage may even lead to geological subsidence, causing casualties, which has always been the main failure affecting the safe and economic operation of the pipe network. With the rapid development of domestic central heating in recent years, the heating area and the scale of the pipe network continue to expand. In particular, traditional thermal power plants are actively developing combined heat and power (such as low-vacuum transformation, cylinder cutting, etc.) Transformation, circulating water waste heat utilization, etc.), the safety of heating network operation has an increasing impact on t...
