Description

Technical Field

[0001] The utility model relates to the technical field of heat energy recovery, in particular to a heat recovery heater for heat supply in a power plant. Background Art

[0002] In traditional power plants, fuels such as coal and natural gas are burned to produce high-temperature and high-pressure steam, which is used to drive the turbine to rotate and then drive the generator to generate electricity. However, after completing the power generation task, these steams generate a large amount of waste heat. This waste heat is usually discharged through condensed water, and the temperature of condensed water is relatively low, which not only causes a waste of energy, but also pollutes the discharged water body. The Chinese patent application number is: 202223280985.7, a new type of heat recovery heater used for heating in power plants, and its beneficial effects are: the new type of heat recovery heater used for heating in power plants can rotate the sleeve to make the gear ring drive the gear to rotate, so that the bolt rotates and disengages in the threaded hole to achieve the separation of the tank cover and the tank body, and the T-rod can be rotated to make one end of the T-rod flush with the third through groove and then pull the connector to make the T-rod disengage from the connecting block. Due to the extrusion of the spring, the baffle and the synchronization block drive the T-rod to achieve the alignment of the heat pipe and the connecting pipe. The heat converter can be connected and separated, and the threaded rod can be driven to rotate by a motor, so that the internal thread block drives the bearing plate on one side to move, and the heat converter can be moved up and down along the tank body, so as to facilitate the maintenance of the heat converter. Although the above case is convenient for disassembly and maintenance of the main body, it is necessary to drive the baffle to move, and at the same time, there are a lot of gaps in its internal space, which reduces the efficiency of heat recovery of the main body. In addition, the tank body of the existing heat recovery heater for heating in power plants is usually an integrated connection. When the steam enters the tank body, it will directly contact the drain pipe. Since the steam contains a lot of heat, it will cause damage to the drain pipe. After long-term use, performance degradation or failure will occur, which will reduce the main body's absorption of steam heat. Utility Model Content
