Fig. 1 is the cross-sectional view of a kind of embodiment of fuel vapor residual heat from boiler fume recycle device described in the utility model;
Fig. 2 is the vertical view of fuel vapor residual heat from boiler fume recycle device shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model, structure and the course of work are further described.
A kind of embodiment of the described fuel vapor residual heat from boiler fume of utility model recycle device, as shown in Figure 1 and Figure 2, comprise cylindrical shell 1, be arranged on the blowoff valve 10 of cylindrical shell 1 bottom, the hot-tub 9 of cylindrical shell 1 below, the smoke inlet 14 of cylindrical shell 1 wall middle and lower part, the exhanst gas outlet 13 at the header tank 2 of cylindrical shell 1 top and cylindrical shell 1 top; In the middle of cylindrical shell 1 adopts for cylindrical, two ends are conical structure up and down; Header tank 2 adopts circulus, and it is made up of circulating line 21 and the passage 22 by the center of circle, and header tank 2 bottoms (comprising circulating line 21 and passage 22) are equipped with a plurality of shower nozzles 3; Between header tank 2 and hot-tub 9, be provided with circulation, this system is made up of one group of stop valve 7, filter 4 and water circulating pump 5 that is arranged on the cylindrical shell outside, filter 41 is connected in parallel with filter 42, filter 41 1 ends are connected with stop valve 71, the other end is connected with stop valve 72, filter 42 1 ends are connected with stop valve 73, the other end is connected with stop valve 74, stop valve 71 is connected with hot-tub 9 with stop valve 73, stop valve 72 is connected with water circulating pump 5 with stop valve 74, and water circulating pump 5 is connected with header tank 2; Also be provided with water compensating valve 6 between water circulating pump 5 and the stop valve 72,74; Smoke inlet 14 is tangent with cylindrical shell 1, and it is arranged on the highest liquid level place of cylindrical shell 1 wall near hot-tub 9; Be provided with heat exchanger coil 8 in the hot-tub 9, in hot-tub 9, be provided with hot water outlet 12 below the highest liquid level.
The flue gas that boiler is discharged tangentially enters in the cylindrical shell 1 by flue entrance 14, after entering, flue gas rises twist, carry out the contact heat exchange with the water droplet of ejection in the shower nozzle 3, discharge from the exhanst gas outlet 13 at top then, because flue gas is spiral escalation, under action of centrifugal force, the aqueous water in the flue gas is separated, and flows down along cylindrical shell 1 inwall.
