Background technology
At present country pays much attention to energy-conserving and environment-protective, and clearly proposes at the energy conservation object that the Eleventh Five-Year Plan period reaches 20%.Along with the minimizing gradually of coal-burning boiler, fuel oil, gas fired-boiler user get more and more, and diesel oil, Gas Prices rise steadily simultaneously, and use cost is more and more higher, make energy-saving and cost-reducing equipment be subjected to more and more people's attention.And domestic relevant device energy-saving efficiency is low, generally only sensible heat is used, for example: economizer, coil pipe etc., energy-saving efficiency is many below 5%, and service life of equipment is short, and maintenance is inconvenient, and equipment is in a single day damaged, and boiler can't be moved.
The utility model content
The purpose of this utility model is that a kind of oil-burning gas-fired boiler flue gas condensing device will be provided.Enable to make full use of sensible heat and vapour latent heat in the boiler smoke, the energy-saving efficiency height, and can also absorb sulfide in the flue gas, nitride etc., make the flue gas environmental protection more, the health that are emitted in the atmosphere; And it is rational in infrastructure, easy to maintenance, safe in utilization.
The purpose of this utility model is achieved through the following technical solutions: be provided with a smoke-intake pipe that is communicated with former boiler flue, smoke-intake pipe is communicated with the heat exchange of heat pipe lower end, the heat exchange of heat pipe middle part is provided with a dividing plate, it is heating water tank that heat exchange of heat pipe is divided into top, the bottom is two chambeies of flue, connect heat conduction with some heat pipes in the middle of two chambeies, the flue of heat exchange of heat pipe cavity of resorption is communicated with the condensation flue of back, in the condensation flue, arranging the condensation screen cloth that is distributed with tiny sieve aperture above several, the top of condensation flue is provided with a spray head, condensation flue bottom is provided with water tank, water in the water tank is communicated with heat exchanger upper end one side by circulating pump, and opposite side is communicated with by the spray head of circulating water pipe with condensation flue top; High-performance heat exchanger bottom one side is communicated with running water, and the opposite side of high-performance heat exchanger upper end is communicated with the heating water tank water inlet pipe on heat exchange of heat pipe top by another road water pipe.
Be provided with an air valve door in the boiler flue of described smoke-intake pipe front end.
Described heat exchange of heat pipe casing is trapezoidal, helps flowing of flue gas.Because along with the decline of flue-gas temperature, flue gas volume can be dwindled gradually and be influenced flue gas flow rate, and trapezoidal design helps flue gas flow rate and stably enters the condensation flue.
Be welded with a lot of fins on the described heat pipe, to increase heat absorption and area of dissipation.
Described heat pipe becomes 30-80 degree angle with dividing plate, to help intraductal working medium condensing reflux quickly.
Described condensation screen cloth becomes 30-90 degree angle with the condensation walling of flue.The condensation screen cloth can be the formula that staggers, also can be for spiral.
The utility model has made full use of sensible heat and the vapour latent heat in the oil-burning gas-fired boiler flue gas, the energy-saving efficiency height, energy-saving efficiency generally can reach 8-16%, and can also absorb water, sulfide, nitride in the flue gas, makes the flue gas environmental protection more, the health that are discharged in the atmosphere; And it is rational in infrastructure, easy to maintenance, safe in utilization.

Fig. 1 is the utility model one embodiment general structure schematic diagram;
Fig. 2 is a condensation mesh structure schematic diagram among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment:
With reference to accompanying drawing:
Flue gas in the boiler 1 enters in the smoke-intake pipe 4 after being stopped by the air valve door 3 in the flue in flue 2, enter then in the flue of heat exchange of heat pipe 5 bottoms, the heat exchange of heat pipe casing is trapezoidal, help flowing of flue gas, the heat exchange of heat pipe middle part is provided with a dividing plate 16, heat exchange of heat pipe is divided into two chambeies up and down, top is the heating water tank 7 that is communicated with boiler 8, the bottom is the flue that is communicated with the condensation flue 12 of back, connect heat conduction with some heat pipes 6 in the middle of two chambeies, the heat pipe of present embodiment adopts single pipe, convenient maintenance and replacement, and single heat pipe damages the use that can not influence boiler and condensing unit.Heat pipe becomes 30-80 degree angle with dividing plate, help intraductal working medium condensing reflux quickly; On each root heat pipe, be welded with a lot of fins, to increase heat absorption and area of dissipation; Be filled with a certain proportion of heat-conducting work medium in the pipe, when high-temperature flue gas washes away the heat pipe bottom, intraductal working medium is moved upward to the top by rapid evaporation gasification and is heated by heat pipe wall and flows down along inner tubal wall after water condensation in the water tank 7 discharges heat energy, and constantly tape loop is walked heat, reduced flue-gas temperature.Entered in the vertical condensation flue 12 by the flue gas after heat exchange of heat pipe 5 coolings.Staggered the condensation screen cloth 14 that is distributed with tiny sieve aperture above several in condensation flue 12, the condensation screen cloth becomes 30-90 degree angle with the condensation walling of flue.The top of condensation flue 12 is provided with spray head 15, and condensation flue bottom is provided with condensation water tank 9, and the water in the condensation water tank is communicated with high-performance heat exchanger 10 upper ends one side by circulating pump 11; High-performance heat exchanger bottom one side is communicated with running water pipe 17, and the opposite side of bottom is communicated with spray head 15 by circulating water pipe 13-1.
