Descaling and antiscaling generator cooling device and antiscaling method

Abstract

The invention discloses a descaling and antiscaling generator cooling device, which comprises a feeding chamber capable of accommodating inert solid particles, and a cooler, wherein a cooling cavity of the cooler is communicated with a generator by means of a pipeline. The inert solid particles are added into cooling water of the cooler by means of the feeding chamber, a solute is prevented from forming a degree of supersaturation in a boundary layer solution by utilizing the damage of the fluidized inert solid particles to a boundary layer and stirring the cooling water, thereby prolonging an induction period of scaling, and achieving the antiscaling purpose; in addition, a heat transfer coefficient of the cooling water is increased due to the inert solid particles, so that the wall temperature of a cooling pipeline decreases, thereby being advantageous for antiscaling. The invention further discloses an antiscaling method of the generator cooling device. According to the antiscaling method, the inert solid particles are introduced into the cooling liquid of the generator cooling device, so that the cooling liquid has a fluidized bed type liquid-solid contact state, and the solute in the cooling liquid is prevented from forming the degree of supersaturation in the boundary layer solution, thereby achieving the purpose of antiscaling.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to a cooling device for a descaling and anti-scaling generator and an anti-scaling method. Background technique [0002] Thermal power generation is a power generation method that utilizes the heat energy generated when combustibles are burned and converts it into electrical energy through a power generation device. China is rich in coal resources, and thermal power generation still has great potential today. Thermal power generation generally refers to the general term for using the heat energy generated by the combustion of combustibles to heat water, turning the water into high-temperature, high-pressure water vapor, and then using the water vapor to drive a generator to generate electricity. The process of thermal power generation varies according to the prime mover used. In the steam turbine power generation method, the basic process is to first feed the fuel into the bo...
