Abstract
The utility model discloses an energy saving bot blast furnace. The energy saving bot blast furnace comprises a furnace body (6); a furnace chamber (1) is formed in the furnace body (6); an outlet of the furnace chamber (1) is connected with a smoke outlet (3) through a smoke discharging pipe and a heat exchanger (2); one side of the furnace body (6) is provided with a cold air inlet (5) which is connected with the heat exchanger (2); the cold air inlet (5) is connected with a hot air outlet (4) through the heat exchanger (2); heating pipes of the heat exchanger (2) in a double return mode; heating pipelines of the heat exchanger (2) are in seamless tube tubular type double return heat exchanging structures. The energy saving bot blast furnace has the advantages of being good in heating effect and high in energy utilization rate and guaranteeing the product quality due to the fact that the heat exchanger is arranged in the double return mode.
Description
Technical field
The utility model relates to drying plant, relates to a kind of energy-saving hot blast furnace.
Background technology
Traditional hot-blast stove structural design is simple, because the heating tube of heat exchanger adopts general single backhaul to arrange, and the heating weak effect, heat time heating time is long, and energy utilization rate is lower; In addition, because the heat exchanger tube of heat exchanger often adopts welded tube, service life is low, and breakage very easily takes place, and causes in the clean oven dry gas and sneaks into flue gas, thereby influence the quality of product.
Summary of the invention
At the shortcoming of existing hot-blast stove, the utility model provides a kind of energy-saving hot blast furnace.
To achieve these goals, the measure taked of the utility model:
A kind of energy-saving hot blast furnace, comprise body of heater, be provided with burner hearth in the body of heater, the outlet of burner hearth is connected with exhanst gas outlet by smoke exhaust pipe and heat exchanger, body of heater one side is provided with the inlet of cold air that is connected with heat exchanger, cold implication import is connected with hot air outlet by heat exchanger, and the water back of heat exchanger adopts two backhauls to arrange.
The water back of heat exchanger adopts the two backhaul heat exchange structures of seamless pipe shell and tube.
The beneficial effects of the utility model: heat exchanger adopts two backhauls to arrange, heat effective, the energy utilization rate height, product quality is guaranteed.
Description of drawings
Fig. 1, structural representation of the present utility model.
The specific embodiment
A kind of energy-saving hot blast furnace, comprise body of heater 6, be provided with burner hearth 1 in the body of heater 6, the outlet of burner hearth 1 is connected with exhanst gas outlet 3 by smoke exhaust pipe and heat exchanger 2, body of heater 6 one sides are provided with the inlet of cold air 5 that is connected with heat exchanger 2, cold implication import 5 is connected with hot air outlet 4 by heat exchanger 2, and the heating tube of heat exchanger 2 adopts two backhauls to arrange that the water back of heat exchanger 2 adopts seamless steel pipe.During work, fuel is in burner hearth 1 internal combustion, burning back flue gas enters heat exchanger 2, the heating tube of heat exchanging device 2 heats, useless flue gas passes heat exchanger 2 backs and discharges from exhanst gas outlet 3, when cold air passes through heat exchanger 2, become hot-air after heat exchanger 2 heating, the hot-air after being heated is discharged by hot air outlet 4 and is transported in the corresponding dryer.The beneficial effects of the utility model: heat exchanger adopts two backhauls to arrange, heat effective, the energy utilization rate height, product quality is guaranteed.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
