Description
Technical field
The utility model relates to the device of the cooling of a kind of sintering machine flue gas, waste heat recovery.
Background technology
Fossil energy and the electric energy such as coke is consumed in a large number in steel and iron industry sintering production process, produce a large amount of high-temperature flue gas (flue-gas temperature is 350oC-450oC), because industrial sintering machine smoke contamination is serious, the sack cleaner that efficiency of dust collection is high need be adopted, environment protection standard emission request could be met, but bag-type duster filtering bag normal operating temperature is less than 130 DEG C, if sack cleaner easily damages by flue-gas temperature height.As adopted ventilation blower that flue gas is carried out air cooling, then have that volume is large, consume energy high shortcoming; According to flue misting cooling, the easy fouling of flue, filter bag of dust collector easily sticks with paste bag, increases resistance and maybe cannot run.In addition, no matter be air cooling or misting cooling, the waste heat in flue gas is all underutilized and emptying waste in vain.
Summary of the invention
The purpose of this utility model is to propose a kind of flue gas cool-down, waste-heat recovery device, and it adopts water screen tube to absorb heat, and absorbing and cooling temperature is effective, for cleaner provides suitable temperature conditions, and waste heat can be reclaimed.
The purpose of this utility model is achieved in that a kind of flue gas cool-down, waste-heat recovery device, comprises flue, and described flue upper and lower part is provided with exhanst gas outlet flange and gas approach flange respectively; Described flue periphery is provided with ring-shaped water jacket, and described ring-shaped water jacket outer wall is provided with water inlet and delivery port; Described flue inside is provided with some being intervally arranged and acclivitous water screen tube, and the two ends of described water screen tube all communicate with ring-shaped water jacket.
Further, described ring-shaped water jacket outer wall bottom is provided with sewage draining exit.
Further, described ring-shaped water jacket outer wall top is provided with overfall.
Further, described ring-shaped water jacket outer wall is provided with liquid level gauge.
Further, described ring-shaped water jacket outer wall top is provided with exhaust outlet.
Further, described exhaust outlet is provided with safety valve.
High-temperature flue gas and water screen tube can be carried out heat exchange by flue gas cool-down of the present utility model, waste-heat recovery device, make high-temperature flue gas fast cooling on the one hand, ensure that follow-up sack cleaner normally runs; On the other hand, the hot water that heat exchange produces can be used for winter heating, bathing, also can produce steam, realize flue gas heat recovery.The utility model structure is simple, floor space is little, operating cost is low, is suitable for the boiler of sintering machine and all kinds of high fume temperature, kiln.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the overall structure schematic diagram of flue gas cool-down, waste-heat recovery device;
Fig. 2 is the partial structurtes schematic diagram of flue gas cool-down, waste-heat recovery device.
Legend: 1. exhanst gas outlet flange, 2. exhaust outlet, 3. liquid level gauge, 4. water inlet, 5. gas approach flange, 6. flue, 7. sewage draining exit, 8. ring-shaped water jacket, 9. delivery port, 10. water screen tube, 11. overfalls.
Detailed description of the invention
The utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1-2, a kind of flue gas cool-down, waste-heat recovery device, comprise flue 6, and flue 6 upper and lower part is provided with exhanst gas outlet flange 1 and gas approach flange 5 respectively; Flue 6 periphery is provided with ring-shaped water jacket 8, and ring-shaped water jacket 8 outer wall is provided with water inlet 4 and delivery port 9; Flue 6 inside is provided with some being intervally arranged and acclivitous water screen tube 10, and the two ends of water screen tube 10 all communicate with ring-shaped water jacket 8.
To be applied to SINTERING PRODUCTION, during use, gas approach flange 5 connects rear of sintering machine, and exhanst gas outlet flange 1 connects sack cleaner, and high-temperature flue gas upwards enters flue 6 from rear of sintering machine, flue gas contacts with water screen tube 10 when flue 6, heat energy is passed to the liquid in water screen tube, water screen tube 10 is inclined upwardly and is conducive to heated liquid and upwards flows, and forms cold and hot exchange, liquid fully absorbs heat, and flue-gas temperature is reduced.Flue gas after cooling enters sack cleaner by exhanst gas outlet flange 1 and carries out dedusting, makes soot emissions environment protection standard.In addition, the liquid of heating accesses the system such as heat supply, bathing by delivery port 9, and water inlet 4 ensures turnover water balance.
Ring-shaped water jacket 8 outer wall bottom is provided with sewage draining exit 7, draining or deslagging during convenient maintenance; Ring-shaped water jacket 8 outer wall top is provided with overfall 11, ensures that liquid is no more than limiting water level; Ring-shaped water jacket 8 outer wall is provided with liquid level gauge 3, is convenient to observe liquid level; Ring-shaped water jacket 8 outer wall top is provided with exhaust outlet 2, discharges internal gas when being convenient to heated liquid; Exhaust outlet 2 is provided with safety valve, prevents hydraulic pressure from exceeding scope of design, the use of exhaust pressure relief, according to normal pressure design, then without the need to mounting safety valve, exhaust outlet 2 is led directly to air.
Obviously, above-mentioned explanation of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
