Abstract

The invention relates to a waste heat recycling system based on a boiler. The waste heat recycling system based on the boiler involves a continuous blowdown expander, a first stop valve, a deoxidizing box, a second stop valve, a heat exchange water tank, an opening degree valve, a drain valve, a water inlet electromagnetic valve, a blowdown valve, a third stop valve, a hot water pump, a liquid level meter, a water temperature sensor, a temperature measuring device, a temperature compensator and a central control module. According to the waste heat recycling system, a pipeline is installed on an emptying pipe of the continuous blowdown expander, and is connected to the heat exchange water tank and a deaerator, the flowing direction of blowdown residual steam is adjusted by controlling the temperature of the blowdown residual steam, the opening degree of the opening degree valve is adjusted by detecting the water temperature and the water level in the heat exchange water tank, and the opening degree of the opening degree valve is verified and the opening degree valve is adjusted by detecting the segmented duration temperature, so that the heating process of the heat exchange water tank is more accurately controlled while the energy of the blowdown residual steam is fully utilized, normal operation of the waste heat recycling system based on the boiler is guaranteed, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of heating equipment systems, in particular to a recovery and utilization system based on boiler waste heat. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire. Furnace refers to the place where fuel is burned. The boiler includes two parts: the boiler and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or regenerated. The boiler that converts mechanical energy into electrical energy through a generator and provides hot wa...
