During use, described combustion chamber 2 is immersed in water A in described condensing heat exchanger 7, flame in combustor 1 and flue gas enter combustion chamber 2 from front end, combustion chamber 2 connecting pipe 21, fire smoke gases is in combustion chamber 2 inside turn, by combustion chamber 2 partition heat passed to the water A in condensing heat exchanger 7, then flue gas enters condensing heat-exchange space from described outlet flue by flue gas flow guiding bend pipe 3, water smoke heat exchange under drenching with the feedwater distributary atomizer 4 from condensing heat exchanger 7 top, finally, flue gas discharges this condensation heat homogeneous solution-type reactor by exhaust opening 6.
Because combustion chamber 2 outlet flue in this condensation heat homogeneous solution-type reactor arranges flue gas flow guiding bend pipe 3, exhanst gas outlet bends towards the front end of combustion chamber and the port of exhanst gas outlet is offered towards oblique below, the design of offering direction of the port of its special structure and exhanst gas outlet, make smoke carry exhaust opening 6 completely to emerge, and then upwards ascension with feedwater distributary atomizer 4 drench under water smoke contact.Described flue gas flow guiding bend pipe, compared with existing cigarette outlet device, can make flue gas be detained in the condensing heat-exchange space longer time, so also just can contact with feedwater better, heat wherein can be made more to stay.Cigarette outlet device of the prior art, its outlet flue be not all towards combustion chamber front end and deviate from exhaust opening direction and offer, the distance of total some flue gas convoluted flow in condensing heat-exchange space is shorter, and therefore, condensation heat homogeneous solution-type reactor flue gas heat exchange effect of the present invention can be better.The cigarette outlet device that described outlet flue on combustion chamber of the prior art is arranged, can more disperse to allow flue gas, structure all designs to obtain more complicated, although the flue gas flow guiding bend pipe that the present invention uses, a just bend pipe, structure is very simple, but makes the meeting of this condensation heat homogeneous solution-type reactor flue gas heat exchange effect better.Have again, usually, above this condensing heat-exchange space, namely described condensing heat exchanger top arrange feed pipe and this feed pipe is connected feed water distributary atomizer 4, to align up and down with cigarette outlet device below, and outlet flue provided by the invention, owing to being provided with described flue gas flow guiding bend pipe, described feedwater distributary atomizer 4 need not align up and down one by one with outlet flue.Like this, condensation heat homogeneous solution-type reactor can be made when the thermal efficiency improves, and structure but becomes simpler.
On described combustion chamber 2, offer some described outlet flues from front to back, the aperture of outlet flue is above larger.Can be more that the front end by described combustion chamber 2 can arrange more outlet flue, outlet flue is then less below.
In prior art, the setting of the outlet flue on combustion chamber will with smoke before and after upper end, combustion chamber evenly for criterion, and the present invention changes the existing practice, allows before combustion chamber, and namely smoke discharging volume is larger more at a distance for distance exhaust opening.Like this, more a large amount of flue gases can do and spiral in condensing heat-exchange space, and with feedwater sufficient heat exchange, the flue-gas temperature of discharge can effectively reduce.
Condensation heat homogeneous solution-type reactor provided by the invention, by arranging described deflector 5, plays two effects: one, is exhaust opening and appearance steam space to keep apart, and the condensed water that exhaust opening 6 condensation is got off directly can not fall into and hold steam space.Common condensation heat homogeneous solution-type reactor, hot water outlet pipe 10 on condensing heat exchanger is generally arranged on the rear end sidewall of condensing heat exchanger, it is corresponding with exhaust opening about 6, in work, cold water under feedwater distributary atomizer 4 drenches can directly drop on the water surface in condensing heat exchanger 7, the condensed water got off from exhaust opening 6 condensation can drop near hot water effluent hole, these also fail to be heated to the water at low temperature of design temperature and condensed water can be discharged in hot water outlet mixing, boiler leaving water temperature will be caused like this to reduce or instability, stablize leaving water temperature then to need to consume more energy.And the present invention is provided with described deflector 5, the water at low temperature fallen and condensed water will flow to the front end of condensing heat exchanger 7 along the deflector 5 tilted, and flow back to hold in steam space to be sufficiently heated by described space.So just can guarantee the stable in outlet water temperature of boiler hot-water; Its two, be stop hold steam space steam rise discharge from exhaust opening 6 rapidly.Why condensation heat homogeneous solution-type reactor exhaust opening of the prior art usually emits white cigarette, reason is that the steam straight line holding steam space rises to condensing heat-exchange space greatly, exhaust opening has little time the heat of this part steam to stay, in addition in exhaust opening punishment separable flue gas, the effect of steam is bad, so both lose a lot of heat, also cause the loss of circulating hot water.And the present invention arranges the deflector 5 of special construction, condensing heat exchanger front end is all directed to by holding the steam produced in steam space, condensing heat-exchange space is entered from described space, then exhaust opening 6 is flowed to circuitously, the barrier that the water smoke that also will spray through feedwater distributary atomizer 4 in way is formed, its temperature is greatly reduced, and can accomplish that substantially all becoming water falls.
As shown in Figure 4 and Figure 5, described feedwater distributary atomizer 4 comprises feed pipe 41, water knockout drum 42, outlet pipe 43 and nozzle 44, described water knockout drum 42 is a cylindrical barrel body, at the sidewall of this cylindrical shell with offer to water hole on going to the bottom, to water hole being connected to outlet pipe 43, this outlet pipe 43 should be connected to nozzle 44 at each.
The lower bottom structure of described cylindrical barrel body can be: it goes to the bottom as centre is lower convex taper type bottom surface, offer described to water hole on the surrounding annular slope of this taper type bottom surface and on frustum bottom surface, outlet pipe should be connected to on water hole at each, this outlet pipe was connected to nozzle.
Feedwater distributary atomizer of the prior art is provided with to water hole usually on the sidewall of its cylindrical shell and bottom surface, sidewall is connected to nozzle on water hole, and on bottom surface to nozzle is not generally established in water hole, and bottom surface is generally at the bottom of plane, the dispersiveness of such feedwater distributary atomizer water outlet is bad.Also the device of good dispersion is had in existing water injector, but its structure all more complicated, especially can not be suitable for using in the boiler.Feedwater distributary atomizer provided by the invention, just by being all connected to nozzle on water hole on cylinder lateral wall and bottom surface, just making feedwater fogging degree increase substantially, coordinating directed flue gas of discharging in flue gas flow guiding bend pipe, can better with smoke contacts, absorb the heat in flue gas.More particularly, in the taper type of the going to the bottom design of feedwater cylindrical shell, the sidewall that frustum tilts also is provided with to water hole, and being connected to nozzle, such feedwater distributary atomizer spray angle is more, can think all to form water spray face at the downward 180 ° of spheres of feedwater distributary atomizer, feed water more even, heat transfer effect is better, and the structure of this feedwater distributary atomizer is very simple, can adapt to the environment of hot humid in the boiler.
