Abstract
The utility model discloses a metallurgy kiln high-temperature flue gas waste heat recovery system which comprises a kiln, a smoke discharging pipe connected with the kiln and a heat exchanger arranged in the smoke discharging pipe. The heat exchanger is connected with a water tank. The water flow direction in the heat exchanger is opposite to the glue gas flow direction in the smoke discharging pipe. By arranging the heat exchanger, heat energy of flue gas in the smoke discharging pipe is converted into heat energy of water in the water tank, meanwhile, the water flow direction in the heat exchanger is arranged to be opposite to the glue gas flow direction in the smoke discharging pipe, flue gas heat energy converting efficiency can be greatly improved, and then severe waste of kiln waste heat resources is avoided.
Description
Technical field
The utility model relates to a kind of residual neat recovering system, in particular, and particularly a kind of metallurgical furnace kiln high-temperature flue gas residual neat recovering system.
Background technology
Metallurgical furnace kiln in use, all can consume a large amount of fuel, and a large amount of flue gas of simultaneous produces, and because the exhaust gas temperature of general stove is all very high, and in stove furnace, temperature is also had to certain requirement, therefore all needs fume afterheat to reclaim.Currently used method is: adopt the mode of waste heat boiler generation steam, but its existence: the efficiency of steaming is all lower, and waste heat can not effectively utilize, and has caused the serious waste of residual heat resources, does not meet the requirement of national energy-saving environmental protection.Therefore, be necessary to design a kind of residual neat recovering system.
Utility model content
The purpose of this utility model is, for existing stove residual heat resources to waste serious technical problem in prior art, to provide a kind of metallurgical furnace kiln high-temperature flue gas residual neat recovering system.
In order to solve problem set forth above, the technical solution adopted in the utility model is: metallurgical furnace kiln high-temperature flue gas residual neat recovering system, comprise stove and the smoke exhaust pipe being connected with stove, it also comprises the heat exchanger of being located in smoke exhaust pipe, this heat exchanger is connected with a water tank, and the water (flow) direction in described heat exchanger is contrary with the flue gas flow direction in described smoke exhaust pipe.
According to a preferred embodiment of the present utility model: described heat exchanger is a screw type heat exchanger tube.
According to a preferred embodiment of the present utility model: the two ends of described heat exchanger are connected with water tank with outlet conduit by inlet channel respectively, and are respectively equipped with water intaking valve and outlet valve on described inlet channel and outlet conduit.
According to a preferred embodiment of the present utility model: be also provided with temperature sensor in described water tank.
Compared with prior art, the beneficial effects of the utility model are: the utility model is converted into the heat energy of the flue gas in smoke exhaust pipe the heat energy of the water in water tank by heat exchanger is set, simultaneously that the water (flow) direction setting in heat exchanger is contrary with the flue gas flow direction in smoke exhaust pipe, can greatly improve the heat energy transformation efficiency of flue gas, and then avoid the serious waste of stove residual heat resources.
Accompanying drawing explanation
Fig. 1. be the structural representation of metallurgical furnace kiln high-temperature flue gas residual neat recovering system of the present utility model.
Description of reference numerals: 10, stove, 20, heat exchanger, 30, water tank, 40, water intaking valve, 50, outlet valve, 60, smoke exhaust pipe.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Consult shown in Fig. 1, the utility model provides a kind of metallurgical furnace kiln high-temperature flue gas residual neat recovering system, comprise stove 10 and the smoke exhaust pipe 60 being connected with stove 10, it also comprises the heat exchanger 20 of being located in smoke exhaust pipe 60, this heat exchanger 20 is connected with water tank 30, and the water (flow) direction in heat exchanger 20 is contrary with the flue gas flow direction in described smoke exhaust pipe 60.
In the utility model, in order further to improve heat exchange area and heat exchange efficiency, described heat exchanger 20 is a screw type heat exchanger tube.
Concrete, in order to improve controllability, the two ends of described heat exchanger 20 are connected with water tank 30 with outlet conduit (not shown) by inlet channel (not shown) respectively, and are respectively equipped with water intaking valve 40 and outlet valve 50 in described inlet channel (not shown) and outlet conduit (not shown).
Meanwhile, in order to facilitate personnel to observe the water temperature in water tank 30, in described water tank 30, be also provided with temperature sensor (not shown); This temperature sensor can be connected with outside display, to further facilitate personnel's observation.
The utility model has the advantage of: 1, by heat exchanger 20 is set, the heat energy of the flue gas in smoke exhaust pipe 60 is converted into the heat energy of the water in water tank 30; 2, the water (flow) direction setting in heat exchanger 20 is contrary with the flue gas flow direction in smoke exhaust pipe, cold water is first absorbed heat from the low temperature of smoke exhaust pipe 60, to high temperature place, absorb heat again, can greatly improve the heat energy transformation efficiency of flue gas, and then avoided the serious waste of stove residual heat resources.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
