A thermal heating system and its method for cumulative leak detection of temperature excursions throughout the day

Abstract

The invention provides a thermal heating system and a leak detection method thereof, comprising a boiler, a heat exchanger and a heating radiator, wherein the boiler, the heat exchanger and the heating radiator are connected through a heating pipe network, and the boiler generates a The steam enters the heat exchanger, exchanges heat with the water in the heat exchanger, and then the water enters the heating radiator for heating, the heating pipe network has a plurality of nodes, and a thermal imager is set at at least one node; 24-hour continuous monitoring of changes in the cumulative sum of temperature offsets, and when the threshold is exceeded, a node leakage alarm is triggered; the alarm method adopts 24-hour cumulative sum of temperature offsets. The invention provides a new heating pipe network system for intelligently detecting leakage and alarming. The invention automatically detects leakage by monitoring the infrared temperature field changes at the nodes of the heating pipe network in real time through an infrared thermal imager. Alarm, making the results more accurate and less error.

Description

technical field [0001] The invention relates to a heat supply system, in particular to the technical field of a heat supply pipe network for intelligent leakage detection. 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 cogeneration (such as low-vacuum transformation, circulating water, etc.) Utilization of waste heat, etc.), which makes the safety of heating network operation more and more influential on the safe operation of power plant uni...
