Abstract

The invention provides a waste heat recovery device for a boiler system and a heat exchange method. The waste heat recovery device for the boiler system comprises a vertical shell and heat exchange assemblies, wherein an air inlet and a water outlet are formed in the shell, and the air inlet is located above the water outlet; part of or all of the heat exchange assemblies are located in the shell,the heat exchange assemblies comprise a plurality of heat exchange pieces, the plurality of heat exchange pieces are arranged at intervals in the height direction of the shell, and to-be-cooled mediawhich enter from the air inlet exchange heat layer by layer through the plurality of heat exchange pieces and then are fully condensed and are discharged to the outer side of the shell from the wateroutlet. According to the waste heat recovery device, the problem of influence on the passing of personnel due to water mist or droplets formed by steam in sewage discharged by the boiler system in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a waste heat recovery device and a heat exchange method for a boiler system. Background technique [0002] At present, boiler blowdown is divided into two forms: continuous blowdown and regular blowdown. According to the parameters and types of boilers, the blowdown rate is usually between 1% and 10%. Such as figure 1 As shown, in the prior art, the blowdown of the boiler is expanded through the continuous blowdown expansion vessel 1' after throttling, and the steam in the blowdown water is led to the deaerator 2', and the deaerator 2' can expand the continuous blowdown vessel. 1' is sprayed with demineralized water to cool the sewage and steam. The cooled sewage is discharged after being cooled by the sewage cooling pool, and the steam is discharged directly to the air, which is easy to form water mist or liquid droplets, especially in winter. Freezing and condensation w...
