Description
Technical field
The present invention relates to a kind of heating plant, particularly recycle the heating plant of vapour latent heat in combustion gas, the oil burning boiler flue gas.
Background technology
Combustion gas, oil burning boiler can produce a large amount of water when burning, it is calculated that 1m
3Combustion of natural gas the time can produce the above water of 1.6kg.Therefore, contain a large amount of water vapours in the flue gas of such boiler emission.In order to utilize this partly latent heat of water vapour, a kind of condenser boiler has appearred at present.In this boiler,, the water vapor condensation in the flue gas is adopted hot purpose to reach by the cold working medium of outside need heating by a condensing heat exchanger.This condensing boiler must need the cold working medium of being heated of enough low temperature when using, and just can make flue-gas temperature drop to the condensation temperature of steam.But the heat supply return water temperature is higher generally speaking, often can't make flue gas drop to due condensation temperature, thereby this condenser boiler is difficult in the heat supply field and promotes the use of.
Summary of the invention
Shortcoming at prior art in the background technology, the invention provides a kind of heating plant of recycling vapour latent heat in combustion gas, the oil burning boiler flue gas, this device can provide the cooling working medium of enough low temperature for combustion gas, oil burning boiler, water vapor condensation in the flue gas is got off, can recycle the condensation heat of steam again, the heat supply backwater is heated.
The present invention includes boiler, absorption heat pump, condensate and heat exchanger and heating tube, described absorption heat pump comprises generator, absorber, evaporimeter, condenser and tube connector; Its design feature is, a described condensation interchanger part is arranged in the flue of described boiler, and its extension is arranged in the evaporimeter of described absorption heat pump, and described heating tube is by the condenser and the absorber of described absorption heat pump.
According to technique scheme, described absorption heat pump is the single-effective absorption heat pump.
According to technique scheme, described absorption heat pump is a double effect absorption type heat pump.
According to technique scheme, also be provided with solution heat exchanger on the generator of described absorption heat pump and the tube connector of absorber.
According to technique scheme, the part of described heating tube in described condenser and absorber is the annular tube bank.
The present invention is by the circulation of flue gas cooling water between evaporimeter and boiler flue condensed water heat exchanger, make a large amount of fume afterheats that comprise steam latent heat obtain reclaiming, and be used for heat supply, make the efficient of combustion gas, oil burning boiler on original basis, be greatly improved.Absorbed the NO in the partial fume owing to coagulate water
x, SO
xDeng pernicious gas, therefore, the present invention reduces the discharge of harmful gases amount when improving boiler efficiency significantly, helps environmental protection.

Fig. 1 is a structural representation of the present invention.
Embodiment
Present embodiment is an example with the single-effective absorption heat pump.As shown in Figure 1: absorption heat pump is made of generator 1, solution heat exchanger 3, absorber 4, condenser 6, evaporimeter 7 and tube connector.Combustion chamber 2 is set, combustion chamber 2 peripheral solution chamber in the generator 1 for sealing.Combustion chamber 2 makes it parse refrigerant vapour and high concentration absorbent to the working medium heating of its peripheral splendid attire; The solution cavity top of absorber 4 is provided with shower nozzle 11-1, and this shower nozzle and solution cavity bottom are communicated with the closed chamber of generator 1 by tube connector respectively and form closed circuit, on the tube connector bottom the solution cavity of absorber 4 pump 5-1 are set.Pump 5-1 is used for the working medium in the absorber 4 is annotated back generator 1; Solution heat exchanger 3 is arranged on the tube connector between generator 1 and the absorber 4, makes the liquid that enters and flow out generator 1 carry out heat exchange; The solution cavity of evaporimeter 7 is communicated with by the solution cavity of tube connector with absorber 4, bottom the solution cavity of evaporimeter 7 and on the tube connector of the shower nozzle on top pump 5-2 is being set; Condenser 6 is communicated with the chamber of generator 1 and evaporimeter 7 respectively by tube connector; Working medium in the generator 1 is ammonia-aqueous solution.During work, being the refrigerant vapour that imports from generator 1 in the condenser 6, is the cryogen solution that condenser 6 flows in the evaporimeter 7, is the absorbent of generator 1 inflow and the refrigerant vapour that sucks from evaporimeter 7 in the absorber 4.
The part of condensation interchanger 8 is arranged in the flue of oil burning boiler 9, this part is made the annular tube bank, to increase the contact area of this part with flue gas; The extension of condensation interchanger 8 is arranged in the evaporimeter 7, and this part is made the annular tube bank.The condensed water of packing in the condensation interchanger 8, and make the condensed water circulation by pump 5-3 disposed thereon; Heating tube 10 passes through absorber 4 and condenser 6, and its part in absorber 4 and condenser 6 is made the annular tube bank, pump 5-4 is set so that the water circulation in the pipe on heating tube 10.
The course of work: the ammonia-aqueous solution in the generator 1 parses refrigerant vapour and absorbent under 2 heating of combustion chamber.Refrigerant vapour enters condenser 6 and the heating tube 10 that is arranged on is wherein carried out condensation by tube connector, discharges condensation latent heat simultaneously and the water in the heating tube 10 are heated, and condensed cryogen enters evaporimeter 7.In evaporimeter 7, by pump 5-2 constantly with cryogen solution from it the shower nozzle 11-2 of portion be injected on the extension of condensation interchanger 8 from its condensed water, to absorb heat, the cryogen solution after the heat absorption is evaporated into refrigerant vapour once more; The high concentration absorbent that parses in the generator 1 enters absorber 4, and absorbs refrigerant vapour by tube connector from evaporimeter 7, discharges heat when absorbing, and the water in the heating tube 10 that is arranged in the absorber 4 is heated.Concentration reduces behind the refrigerant vapour in the high concentration absorbent absorption evaporimeter 7 in the absorber 4, annotates by pump 5-1 then and gets back to generator 1.
The single-effective absorption heat pump of prior art can replace with the double effect absorption type heat pump of prior art in the present embodiment, and being provided with of heat supply water pipe and condensation interchanger is all identical with present embodiment, and its working method is also identical.
