Problems solved by technology

However, if the exhausted flue gas is condensed and absorbed directly through the condensation heat recovery unit described in the document CN201510216073, since the temperature of the flue gas is lower than 30°C, which is lower than that of the heating return water (45°C), the condensed Smoke cannot be used directly

Abstract

The invention provides a high-efficiency condensation heat recovery heating device and method. The high-efficiency condensation heat recovery heating device comprises a condensation heat recovery unit and a smoke heat recoverer, wherein the condensation heat recovery unit is connected with the smoke heat recoverer to form a smoke passage, through which smoke flows from the condensation heat recovery unit to the smoke heat recoverer; and the condensation heat recovery unit is connected together with the smoke heat recoverer through a cold-water circulating pump to form a water circulation. The high-efficiency condensation heat recovery heating device provided by the invention adopts a reasonable structure to recover the smoke produced by the condensation heat recovery unit, so that the latent heat of fuel gas of the condensation heat recovery unit is fully utilized, the heating efficiency COP of the condensation heat recovery unit reaches 1.09 in term of lower calorific value (0.99 in term of higher calorific value), and the heating efficiency is increased by more than 15%; in addition, since the smoke is discharged after being condensed, the effects of eliminating white smoke and reducing nitrogen oxide and sulfur oxide are achieved, energy is saved and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a high-efficiency condensation heat recovery heat supply device and method. Background technique [0002] Lithium bromide absorption chiller and warm water unit is a non-electric heat pump, which uses thermal energy (heat generated by hot water, flue gas, waste steam, etc.) to drive the circulation of lithium bromide solution, thereby transferring heat from low-temperature objects to high-temperature objects. For a long time, the traditional lithium bromide absorption chiller can only provide hot water and cold water alternately, which leads to low energy efficiency ratio and insignificant energy saving effect. [0003] In order to solve the above problems, document CN201510216073 provides a condensing heat recovery unit and a condensing heat recovery method, which uses recycled refrigerant water to realize evaporative refrigeration, thereby improving the energy efficiency ...
