Abstract
The utility model discloses an electric heat pump heater capable of recovering gas-fired oil-fired boiler smoke which comprises a boiler, a heat supply tube and an electric heat pump consisting of a compressor, a condenser, an expansion valve, an evaporator and a connecting tube. The evaporator is arranged in a flue of the boiler. The heat supply tube is through the condenser. The utility model combines the electric heat pump and the gas-fired oil-fired boiler and completely adopts water vapor in the boiler smoke to heat and satisfies low temperature heat source needed by the electric heat pump in prior art, greatly improves the efficiency of oil-fired boiler on original basis and resolves the problem that the electric heat pump in prior art is hardly to be promoted and the gas-fired oil-fired boiler smoke can not be commendably used. The utility model is mainly applicable for heat supply system.
Description
Technical field
The utility model relates to a kind of electric heat pump heating plant, particularly reclaims the electric heat pump heating plant of combustion gas, oil burning boiler flue gas latent heat
Background technology
Electric heating is a kind of cleaning, free of contamination heating mode, and in electric heating, electric heat pump most effective.The electric heat pump heating technology is applied in some places of China.But because problems such as frosting and the decay of freeze-up heating capacity, air source electric heat pump is difficult to apply.Water resource heat pump need could be used in the place with suitable water condition, and the most of regional water resource of China lacks, particularly most of area, the north.Therefore, how finding suitable low-temperature heat source, is that electric heat pump can the fine key of applying.On the other hand, combustion gas in heating system, oil burning boiler use very general.When such boiler combustion natural gas, coal gas or wet goods fuel, can produce a large amount of water, in its discharged flue gas, contain a large amount of steam.In order to utilize the latent heat of this part steam, a kind of condenser boiler has appearred at present.In this boiler,, provide the cold working medium of heating with the water vapor condensation in the flue gas by the outside by a condensing heat exchanger.For this reason, the use of this condensing boiler must have temperature enough low be heated cold working medium, just can make flue-gas temperature reach the condensation temperature of steam.And in heating system, central heating system especially, the temperature of heating backwater is higher, can't be used for steam in the condensation flue gas, thereby can not make heating system directly obtain a large amount of waste heats in the flue gas at lower cost.
The utility model content
At the problem that exists in the background technology, the utility model provides a kind of electric heat pump heating plant that reclaims combustion gas, oil burning boiler flue gas latent heat, this heating plant with electric heat pump and boiler in conjunction with to utilize the low-temperature heat source of residual heat from boiler fume as electric heat pump.
The utility model comprises electric heat pump, boiler and heating tube, and described electric heat pump comprises compressor, condenser, expansion valve, evaporimeter and tube connector; Its design feature is, described evaporimeter is arranged in the flue of described boiler, and described heating tube is by described condenser.
According to technique scheme, described evaporator surface is provided with smoke exhaust pipe.
According to technique scheme, the part that described heating tube is arranged in the condenser is the annular tube bank.
The utility model is with electric heat pump and combustion gas, oil burning boiler combination, utilize the vapour latent heat in the boiler smoke, both solved the required low-temperature heat source of electric heat pump operation in the prior art, the efficient of combustion gas, oil burning boiler is greatly improved on original basis.Owing to had the low-temperature heat source of higher temperature, make the electric heat pump operating efficiency be improved significantly, its energy consumption reduces greatly; And water has also absorbed pernicious gases such as the part NOx in the flue gas, SOx with fixed attention, and the discharge of harmful gases amount is reduced significantly, helps environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, electric heat pump is made up of compressor 1, condenser 2, expansion valve 3, evaporimeter 4 and tube connector.Compressor 1 is connected between condenser 2 and the evaporimeter 4 by tube connector, and expansion valve 3 is connected between condenser 2 and the evaporimeter 4 by tube connector.The surface of evaporimeter 4 is provided with leads smoke pipe 8.Boiler 5 is an oil burning boiler, and the evaporimeter 4 of electric heat pump is arranged in the flue 6 of boiler 5, and flue gas that boiler 5 burnings are produced and water vapour are discharged by leading smoke pipe 8 backs, so that make the flue gas in evaporimeter 4 and the flue 6 carry out sufficient thermal energy exchange.Heating tube 7 passes through condenser 2, and its parts that are arranged in the condenser 2 are made the ring-type tube bank, to increase heat exchange area.During work, perfusion working medium--fluorine Lyons in the evaporimeter 4.
The course of work: boiler 5 discharged flue gas are from leading smoke pipe 8 through out-of-date, evaporimeter 4 absorbs the heat of steam in the flue gas, and fluorine Lyons of adorning in it heated, fluorine Lyons after the heating becomes refrigerant vapour, after compressing, the compressed machine 1 of refrigerant vapour enters in the condenser 2, refrigerant vapour carries out condensation and release heat to heating tube 7 in condenser 2, make the water heating in the heating tube.Convert cryogen solution after the refrigerant vapour release heat to, after expansion valve 3 expands release, enter evaporimeter 4.Circulation and so forth makes that the steam latent heat in the boiler 5 discharging flue gases is absorbed for the required low-temperature heat source of electric heat pump heat supply.
