Waste heat utilization device and method for raw water heating system

Abstract

The invention discloses a waste heat utilization device and method for a raw water heating system. The waste heat utilization device comprises a bottom plate, a storage box and a heat preservation barrel, wherein the bottom of the heat preservation barrel is fixedly connected with the top of the storage box; the bottom of the storage box is fixedly connected with the top of the bottom plate; a supporting plate is fixedly connected between the bottoms of the two sides of the inner wall of the heat preservation barrel; the top of the supporting plate is fixedly connected with a heating barrel; the top of the heating barrel penetrates through the heat preservation barrel and extends to the top of the heat preservation barrel; the bottom of the inner wall of the heating barrel is fixedly connected with an electric heating pipe through a fixing plate; and a fixing frame is fixedly connected to the position, positioned on one side of the heating barrel, of the top of the storage box. The invention relates to the technical field of waste heat utilization. According to the waste heat utilization device and method for the raw water heating system, heat generated by the outer wall of the heating barrel can be transferred into the heat preservation barrel, raw water in the heat preservation barrel is preheated, the subsequent raw water heating efficiency is improved, good conditions are created for subsequent effective utilization of hot water, and the actual use requirements are met.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization, in particular to waste heat utilization equipment and a utilization method of a raw water heating system. Background technique [0002] Waste heat is the energy that is not used in energy utilization equipment under certain economic and technical conditions, that is, redundant and waste energy. Waste heat recovery and utilization is an important way to improve economy and save fuel. There are many ways to recover and utilize waste heat. However, there are three main approaches: direct utilization of waste heat, waste heat power generation, comprehensive utilization of waste heat, direct use of waste heat to preheat air, which uses high-temperature flue exhaust, and uses high-temperature heat exchangers to control the heat entering boilers and industrial kilns. The air is heated. As the temperature of the air entering the furnace increases, the combustion efficiency is improved, the...
