Vacuum steam generating heat exchanger for wall-hung condensing gas furnace

Abstract

The invention relates to a wall-hung vacuum steam generator, in particular to a vacuum steam generating heat exchanger for a wall-hung condensing furnace, which is used for generating steam in the vacuum environment to exchange heat. The vacuum steam generating heat exchanger for the wall-hung condensing furnace integrates a heat exchanger and a vacuum steam generator and comprises a water return pipe, a steam output pipe, a water level observation window, a heat conduction flue gas pipe, a flue gas outlet joint pipe, a flue gas channel separation plate, a flue gas collection channel, a flue gas accumulation channel, a burner, a gas delivery pipe, medium water, a water cavity wall, a water cavity, a shell, heat exchanger blades, a heat exchanger pipe and a heat exchange cavity. The vacuum steam generating heat exchanger for the wall-hung condensing furnace is used for generating steam by heating the processed medium water in the vacuum environment in a circulatory way without treating the heated medium water, thus the scaling of the heat exchanger, the low heat exchange efficiency of the heat exchanger, the burndown of the water tank and other adverse consequences resulted from the scaling of the heat exchanger can be avoided, and the corrosion to the circulating system due to the treatment of the acid in the heated medium water can be reduced.

Description

Technical field: [0001] The invention discloses a vacuum steam generating heat exchanger for a condensing wall-hung boiler, a vacuum steam generator for a wall-hung boiler, and relates to a vacuum steam generator in a gas-fired wall-hung boiler, which is used for generating water vapor in a vacuum environment for heat exchange. Background technique: [0002] At present, the heat exchanger wall of the wall-hung boiler is directly heated by the flame, and the local high temperature of the water in the water pipe is easy to cause scale formation, especially in the use of high hardness water in the west. The adsorption and other methods used in the market cannot effectively remove calcium ions in the water. And magnesium ions, the method of acidification and neutralization is uncontrollable and easy to cause corrosion to the circulation system. Invention content: [0003] The purpose of the present invention is to design and manufacture a vacuum steam generating heat exchanger...
