Embodiment Construction

[0012] This embodiment takes a single-effect absorption heat pump as an example. Such as figure 1 As shown: the absorption heat pump is composed of a generator 1, a solution exchanger 3, an absorber 4, a condenser 6, an evaporator 7 and connecting pipes. A combustion chamber 2 is arranged inside the generator 1, and the periphery of the combustion chamber 2 is a sealed solution chamber. Combustion chamber 2 heats the working medium in its periphery to decompose refrigerant vapor and high-concentration absorbent; the upper part of the solution chamber of absorber 4 is provided with a nozzle 11-1, and the nozzle and the bottom of the solution chamber are respectively connected to the generator through a connecting pipe. The sealed chamber of the absorber 1 communicates and forms a circulation loop, and a pump 5-1 is set on the connecting pipe at the bottom of the solution chamber of the absorber 4 . The pump 5-1 is used to inject the working fluid in the absorber 4 back into t...

Abstract

The present invention discloses heat supply device for recovering latent heat of aqueous vapour in flue gas of fuel oil and fuel gas boiler fume, it includes boiler, condensation heat exchanger, heatsupply pipe and absorption heat pump composed of generator, solution exchanger, absorber, evaporator, condenser and connecting pipe; a part of the said condensation exchanger is set up in gas flue ofthe said boiler and its extended part is set up in the evaporator of absorption heat pump, the said heat supply pipe passes through the condense and the absorber of the said absorption heat pump.

Description

technical field [0001] The invention relates to a heat supply device, in particular to a heat supply device for recovering and utilizing the latent heat of water vapor in flue gas of gas and oil-fired boilers. Background technique [0002] Gas and oil-fired boilers will produce a large amount of water during combustion. According to calculations, 1m 3 More than 1.6kg of water can be produced when natural gas is burned. Therefore, the flue gas discharged from this type of boiler contains a large amount of water vapor. In order to utilize the latent heat of this part of water vapor, a condensing boiler has appeared. In this boiler, through a condensing heat exchanger, the cold working fluid that needs to be heated externally condenses the water vapor in the flue gas to achieve the purpose of heat collection. When this kind of condensing boiler is used, it is necessary to have a heated cold working fluid with a sufficiently low temperature to reduce the temperature of the fl...
