Abstract
The utility model discloses a remove dioxin device, its heat transfer device who belongs to fields such as chemical industry and metallurgy. It mainly includes the heat exchanger body, and heat exchanger body both sides are equipped with flue gas inlet and exhanst gas outlet respectively, the two -period form structure of heat exchanger body for establishing ties in proper order is equipped with water chiller in the first section heat exchanger, is equipped with air cooler in the second section heat exchanger, be equipped with the more than one baffle in the second section heat exchanger. The utility model discloses simple structure, convenient to use adopts the cooling method of two sections differences, reach 2 seconds at the fuel saving, when retrieving the heat in the effect of rapid cooling. The utility model discloses the flue gas cooling in fields such as mainly used chemical industry and metallurgy.
Description
Technical field
This utility model belongs to a kind of heat-exchanger rig in the field such as chemical industry and metallurgy, specifically, particularly relates to a kind of except two English devices.
Background technology
At present, the field such as chemical industry and metallurgy can produce a large amount of high-temperature flue gas in process of production, and the temperature of high-temperature flue gas is 550 600 DEG C. And the generation temperature range of two English is 200 600 DEG C, wherein maximum about the 300 DEG C amounts generated. Existing high-temperature flue gas chiller has straight tubular heat exchanger, economizer etc., but it all needs the longer time when carrying out flue gas cooling, causes generating substantial amounts of two English harmful gass. For controlling the generation of two English harmful gass, it is necessary within 2 seconds, the temperature of high-temperature flue gas is reduced to less than 200 DEG C from 600 DEG C, but there is presently no this device.
Summary of the invention
The purpose of this utility model is in that to overcome drawbacks described above, it is provided that a kind of two English devices that remove, and its its simple in construction is easy to use, adopts the type of cooling two sections different, reaches the effect of chilling in 2 seconds while saving fuel, reclaiming heat.
Described removes two English devices, and including heat exchanger body, heat exchanger body is respectively provided on two sides with gas approach and exhanst gas outlet; Described heat exchanger body is the two-period form structure being sequentially connected in series, and is provided with water cooler, is provided with air cooler in second segment heat exchanger in first paragraph heat exchanger.
Further, it is provided with more than one baffle plate in described second segment heat exchanger.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model adopts cooler two sections different, makes high-temperature flue gas lower the temperature rapidly, effectively controls the generation of two English harmful gass;
2, water cooler ensures the rapid heat exchange of flue gas, and cooling hydromining cooling tower can be recycled after lowering the temperature; As combustion furnace air after the air recovery heat of air cooler, save fuel, greatly reduce cost.
3, baffle plate makes extend the time of contact of flue gas and air cooler, substantially increases heat transfer rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state reference map of the present utility model.
In figure, 1, gas approach; 2, first paragraph heat exchanger; 3, water cooler; 6, second segment heat exchanger; 7, air cooler; 8, exhanst gas outlet; 9, baffle plate; 10, cooling tower; 12, aerator.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As it is shown in figure 1, a kind of two English devices that remove include heat exchanger body, heat exchanger body is respectively provided on two sides with gas approach 1 and exhanst gas outlet 8; Described heat exchanger body is the two-period form structure being sequentially connected in series, and is provided with water cooler 3, is provided with air cooler 7 in second segment heat exchanger 6 in first paragraph heat exchanger 2; More than one baffle plate 9 it is provided with in described second segment heat exchanger 6.
As in figure 2 it is shown, water cooler 3 is connected with cooling tower 10, air cooler 7 is connected with aerator 12. During use, high-temperature flue gas enters heat exchanger body from gas approach 1, sequentially passes through the water cooler 3 in first paragraph heat exchanger 2 and the air cooler 7 in second segment heat exchanger 6, makes high-temperature flue gas be down to 175 200 DEG C by 600 DEG C in 2s; Cooling water cooled tower 10 down cycles after heat exchange uses, and the air after heat exchange uses as combustion furnace air, is greatly saved the energy.
Claims (2)
1., except two English devices, including heat exchanger body, heat exchanger body is respectively provided on two sides with gas approach (1) and exhanst gas outlet (8); It is characterized in that: described heat exchanger body is the two-period form structure being sequentially connected in series, be provided with water cooler (3) in first paragraph heat exchanger (2), in second segment heat exchanger (6), be provided with air cooler (7).
2. according to claim 1 remove two English devices, it is characterised in that: it is provided with more than one baffle plate (9) in described second segment heat exchanger (6).
