Description
Technical Field
The utility model belongs to the technical field of the heating technique and specifically relates to a heating system protection device and relay pump station are related to.
Background
At present, with the continuous development and popularization of the urban central heating industry, the heating range is larger and larger, and the pipe diameter of a heating pipeline is also increased. More and more low-temperature waste heat is also used for central heating, for example, the temperature of slag flushing water in a steel plant is 50-60 ℃ after heat exchange, the temperature of circulating cooling water of a condenser in a thermal power plant is 55-60 ℃, and the low-grade heat energy can be directly used for central heating.
Low temperature water heating has been developed in more and more cities as is typical of energy step utilization. Along with the increase of the heating radius of low-temperature water heating, in order to ensure good hydraulic circulation of a hot water pipeline, a circulating pump is independently arranged at a heat source, so that the requirement of pressure working conditions cannot be met, and a relay pump station needs to be arranged along the pipeline to ensure the pressure balance of a water supply and return pipeline. Because the low-temperature water directly enters the user heating system without passing through the heat exchange station, and the pressure bearing of the user heating system is generally not more than 0.6MPa, the pressure from the pipe network to the user cannot be greater than the pressure bearing of the user heating system. Because of the terrain height difference, the heat source is at a high position, the user is at a low position, and if the terrain height difference is larger than the bearing pressure of the heating system of the user at the low position, the heating system of the user has overpressure only under the condition of water filling and pressure fixing of the heat supply network. If the circulating pump is started, the pressure of the water supply pipeline is reduced to be lower than the pressure bearing of the heating system before reaching the user heating system due to the resistance of the pipeline, so that the pressure of the user is not over-pressurized when hot water in the pipeline circularly runs, and once the power failure causes the heat source or the circulating pump of the relay pump station to stop working, the water pressure in the pipe network is recovered to the hydrostatic pressure, and the user system still can be over-pressurized. On one hand, overpressure can cause pipe explosion of a user heat dissipation system, and heat supply safety is affected; on the other hand, hot water leakage can be caused, heat and water resource waste is caused, and the requirements of safety and energy conservation in the heat supply industry are not met.
In addition, because the low-temperature water has low heating temperature, small temperature difference of supply and return water and large circulating water amount, the traditional water supplementing mode only supplements water at a heat source and fixes the pressure, and the problems of unstable fixed pressure, overlarge model selection of a water supplementing pump and the like can be caused.
