The utility model solves the difficult popularization and application problem in a heating supply field because of the cold refrigerant of the condensed boilers in prior art, and the utility model is mainly used to recycle waste heat of flue gases of the gas and fuel boilers in the heat supply system.
Description
Technical field
The utility model relates to a kind of heating plant, particularly reclaims 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.
The utility model content
Shortcoming at prior art in the background technology, the utility model provides a kind of heating plant that reclaims 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 utility model comprises boiler, absorption heat pump and heating tube, and described absorption heat pump is made of generator, absorber, evaporimeter, condenser and tube connector; Its design feature is, described evaporimeter is arranged in the flue of described boiler, 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.
According to technique scheme, described evaporator surface is provided with smoke exhaust pipe.
The utility model connects and flue gas heat exchange by the evaporator man of absorption heat pump is upright, makes the water vapour condensation in the flue gas, thereby with a large amount of flue gas waste heat recoveries and be used for heat supply, makes the efficient of combustion gas, oil burning boiler be greatly improved on original basis.Because the water that coagulates in the flue gas has absorbed the NO in the partial fume
x, SO
xDeng pernicious gas.Therefore, the utility model also correspondingly makes the discharge of harmful gases amount reduce significantly when improving boiler efficiency, helps environmental protection.

Fig. 1 is a structural representation of the present utility model.
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, 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; Evaporimeter 7 is arranged in the flue of boiler 8, and its solution cavity 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.In the two sides of evaporimeter 7 10 smoke exhaust pipes 9 are set respectively, described boiler 8 discharged flue gas from smoke exhaust pipe 9 by and carry out heat exchange with evaporimeter 7; Condenser 6 is communicated with the chamber of generator 1 and evaporimeter 7 respectively by tube connector.Heating tube 10 is by absorber 4 and condenser 6, and its part absorber 4 and condenser 6 in is made the annular tube bank, on heating tube, be provided with pump 5-3 with so that the water in the heating tube 10 circulate.
Working medium in the generator 1 is the mono-potency lithium bromide 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 course of work: the working media in the generator 1 parses refrigerant vapour and absorbent under the heating of high temperature heat source 2.Refrigerant vapour enters condenser 6 and the heating tube that is arranged on is wherein carried out condensation by tube connector, discharges condensation latent heat simultaneously and the water in the heating tube is heated, and condensed cryogen enters evaporimeter 7.In evaporimeter 7, by pump 5-2 constantly from it the shower nozzle of portion be injected in smoke exhaust pipe 9 the surface with heat absorption, 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 in the 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 evaporimeter is all identical with present embodiment, and its working method is also identical.
