The utility model content

The purpose of this utility model provides a kind of simple in structure, and fuel vapor boiler (kiln) the flue gas waste heat recovery use device that cost is low, heat-transfer effect is good is to improve the combustion apparatus thermal efficiency.

The technical solution of the utility model is: a kind of fuel vapor residual heat from boiler fume recycle device, and according to the utility model, it comprises housing, described housing bottom is provided with blowoff valve; The below is provided with hot-tub in the described housing, is provided with heat exchanger coil in the described hot-tub; Described housing wall middle and lower part is provided with smoke inlet; The top is provided with header tank in the described housing, on the described header tank shower nozzle is installed; Described case top is provided with exhanst gas outlet; Be provided with circulation between described header tank and the described hot-tub, described circulation comprises stop valve, filter and the water circulating pump that is arranged on hull outside, described filter two ends are connected with stop valve respectively, one of them stop valve is connected with described hot-tub, another stop valve is connected with described water circulating pump, and described water circulating pump is connected with described header tank.

Preferably, described housing is middle for cylindrical, and two ends are respectively conical up and down.

Preferably, described smoke inlet and described housing are tangent.

Preferably, described smoke inlet is arranged on the highest liquid level place near described hot-tub.

Preferably, described header tank is a loop configuration.

Preferably, described hull outside is provided with two filters, and described two filters are connected in parallel.

Preferably, be provided with the float-ball type liquid level gauge in the described housing.

Preferably, be provided with water compensating valve between described another stop valve and the described water circulating pump.

The beneficial effects of the utility model are: the utility model adopts the direct contact heat transfer mode, makes cold water and flue gas directly carry out heat exchange, fully absorbs the waste heat in the flue gas; And then the higher characteristics of the heat transfer intensity that utilizes water, adopt the coiled heat exchange mode, not only can make full use of the waste heat in the flue gas, can also reduce discharging pollutants in the flue gas.The utility model is simple and compact for structure, and the installation and maintenance cost is all very low, and does not need to change the structure of existing boiler, and the waste heat in the flue gas is utilized fully, does not have the steel pipe heating surface, saves tubing, scaling not, and the life-span is long.

Description of drawings

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.
