Waste heat recovery device and waste heat recovery method for desalted and deoxygenated water heat absorption boiler

Abstract

The invention discloses a waste heat recovery device for a desalted and deoxygenated water heat absorption boiler. The waste heat recovery device for the desalted and deoxygenated water heat absorption boiler comprises a boiler, and the boiler and a waste heat box are detachably installed through a waste heat recovery pipe, a communicating box is installed on one side of the waste heat box in a communicating mode, a first butt joint pipe is arranged on the waste heat recovery pipe, and the first butt joint pipe and a second butt joint pipe in the waste heat box are arranged in a butt joint and communicating mode; the waste heat recovery pipe is further provided with a fixing clamping column, and the fixing clamping column is connected with a fixing clamping groove in the communication box in a clamped mode. According to the waste heat recovery device, a power motor rotates, a fourth bevel gear drives a third bevel gear to rotate, meanwhile, a transmission rotating shaft rotates, rotation of a waste heat longitudinal shaft and a rotating worm is achieved, then rotation of the waste heat longitudinal shaft and left-right movement of a waste heat transverse shaft can be achieved, stirring of water in the device is improved, the waste heat recovery efficiency is improved, heat generated by the boiler, waste heat is recycled through the waste heat box, so that waste heat is continuously recycled through continuous stirring of a internal structure, and the waste heat recycling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of boiler waste heat recovery, in particular to a waste heat recovery device and a waste heat recovery method for a desalination and deoxygenation water heat-absorbing boiler. Background technique [0002] Boilers that use the sensible heat of various waste gases and waste heat after waste incineration as heat sources are called waste heat boilers, also known as waste heat boilers. In the traditional waste heat boiler power generation system, by heating and pressurizing the boiler feed water to the waste heat boiler body, the steam turbine can realize the steam work, and complete the heat energy conversion to drive the generator to generate electricity. Common waste heat boilers generally use smoke tubes for heat exchange, and there is roughly a multiple relationship between the minimum wall temperature of the metal heating surface and the discharge temperature of the thermal fluid. In the design of waste h...
