Abstract
The invention relates to a smelting furnace waste heat recovery system for aluminum ingot production. The smelting furnace waste heat recovery system comprises a boiler water supplementing pipe, a smelting furnace flue and a shell. Innovations of the smelting furnace waste heat recovery system include that glands are arranged on two sides of the shell, a partition is arranged between each gland and the shell, a plurality of parallel stainless steel pipes are mounted between the partitions, two ends of each parallel stainless steel pipe are communicated with the glands, a water supplementing pipe inlet and a water supplementing pipe outlet communicated with the boiler water supplementing pipe are formed in the two glands respectively, and an inlet and an outlet communicated with the flue are formed in the shell. The stainless steel pipes are corrugated pipes. When water is supplemented to a boiler, the water enters the glands and the stainless steel pipes firstly, flue gas in the smelting furnace flue enters the shell to exchange heat with the water in the stainless steel pipes and the glands, and temperature of supplementary water is increased while temperature of the flue gas is decreased, so that gas blockage caused by large temperature difference is avoided during water supplementing, and normal gas supply of the boiler is guaranteed. The stainless steel pipes are the corrugated pipes, so that heat exchange area can be increased, and the flue gas is prevented from scaling on the corrugated pipes by the aid of a principle of heat expansion and contraction.
Description
Technical field
The present invention relates to a kind of boiler, particularly a kind of aluminium ingot production smelting furnace residual neat recovering system.
Background technology
Heat energy or other heat energy heating waters or other working medium that boiler utilizes fuel combustion to discharge, to produce the equipment of steam, hot water or other working medium of stipulating parameter (temperature, pressure) and quality.In the boiler use procedure, need to carry out moisturizing to it.Conventional moisturizing temperature, in 40 degree left and right, when a large amount of moisturizing, can cause the boiler fast cooling, forms gas stifled, affects normal steam supply.And aluminium ingot production uses smelting furnace when the discharge flue gas, its temperature is higher, and directly discharge has caused the waste of the energy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of aluminium ingot production smelting furnace residual neat recovering system, can take full advantage of the heat energy of smelting furnace, and can avoid boiler to produce the stifled phenomenon of gas.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of aluminium ingot production smelting furnace residual neat recovering system, comprise the smelting furnace flue, it is characterized in that: also comprise a housing, described housing both sides arrange end socket, between end socket and housing, dividing plate are set, some stainless steel tubes that be arranged in parallel are installed between dividing plate, the stainless steel tube two ends are communicated with end socket, open respectively the filling pipe import and the outlet that are communicated with the boiler replenishing water pipe on two end sockets, open the import and the outlet that are communicated with flue on housing; And described stainless steel tube is bellows, and described bellows is set to arc towards a side of chimney intake.
The invention has the advantages that: during boiler replenishing water, at first water enter in end socket and stainless steel tube, flue gas in the smelting furnace flue enters in housing, with the hydrothermal exchange in stainless steel tube and end socket, the supplementing water temperature of boiler is supplied with in lifting as hot water for life, reduce flue-gas temperature, boiler is not prone to the stifled phenomenon of gas simultaneously.Stainless steel tube is bellows, can improve heat exchange area, and utilizes the principle of expanding with heat and contract with cold to avoid flue gas fouling on bellows.Utilize the intrados of bellows to be held back flue gas, improve exhaust heat utilization effect.
The accompanying drawing explanation
Fig. 1 is smelting furnace residual neat recovering system structural representation for aluminium ingot production of the present invention.
The specific embodiment
As shown in Figure 1, comprise boiler replenishing water pipe 1 and smelting furnace flue 2, also comprise a housing 3, in housing 3 both sides, end socket 4 is set, between end socket 4 and housing 3, dividing plate 5 is set, some stainless steel tubes that be arranged in parallel 6 are installed between dividing plate 5, this stainless steel tube 6 is bellows, stainless steel tube 6 two ends are communicated with end socket 4, open respectively filling pipe import and the outlet be communicated with boiler replenishing water pipe 1 on two end sockets 4, open the import and the outlet that are communicated with flue on housing 3, and described bellows is set to arc towards a side of chimney intake.
Operation principle: boiler replenishing water pipe 1 is to boiler replenishing water the time, and water is introduced in end socket 4 and stainless steel tube 6, and the flue gas in itself and smelting furnace flue 2 carries out heat exchange, improves the temperature of water.
