The device also comprises a proportioning box, four threaded rods, four threaded pipes, a second flange, a material conveying pipe, a communicating hose, a first motor, four ball bearings, a first transmission shaft anda first stirring blade.

Description

technical field [0001] The invention relates to the technical field of waste heat attachment devices, in particular to a waste heat utilization device for the first heating station. Background technique [0002] As we all know, after the superheated steam with thermal potential energy is introduced into the steam turbine through the pipeline, the thermal potential energy will be converted into kinetic energy, and the high-speed steam will push the rotor of the steam turbine to rotate to form mechanical energy. Exhaust steam is exhausted from the exhaust port. The exhaust steam is used as the heat source of the first heating station. A large amount of exhaust steam is wasted in the process of driving the steam turbine to do work by the high-speed circulating steam. The waste heat utilization device used for the first heating station is An auxiliary device for recycling the exhaust steam of the first station of heating, which has been widely used in the fields of thermal power...

[0002] As we all know, after the superheated steam with thermal potential energy is introduced into the steam turbine through the pipeline, the thermal potential energy will be converted into kinetic energy, and the high-speed steam will push the rotor of the steam turbine to rotate to form mechanical energy. Exhaust steam is exhausted from the exhaust port. The exhaust steam is used as the heat source of the first heating station. A large amount of exhaust steam is wasted in the process of driving the steam turbine to do work by the high-speed circulating steam. The waste heat utilization device used for the first heating station is An auxiliary device for recycling the exhaust steam of the first station of heating, which has been widely used in the fields of thermal power generation and heating; the existing waste heat utilization device for the first station of heating includes water tanks, water tanks There is a storage chamber inside, an air intake pipe is provided at the left end of the water tank, an exhaust pipe and a water inlet pipe are provided at the top of the water tank, and an outlet pipe is provided at the right end of the water tank; The exhaust steam is introduced into the storage chamber from the air intake pipe to heat the water in the water tank, and then the heated water is used to recover the waste heat; it is found in the use of the existing waste heat utilization device for the first station of heating that it is not effective for exhaust The effective utilization rate of the steam is low, resulting in low practicability; and the large temperature difference in the process of contacting the exhausted steam with water is prone to scale, and it is inconvenient to deal with the scale in the water tank, resulting in low reliability
