Description

A kind of Water pipe heating pipe afterheat boiler system be built on sintering machine flue
Technical field
The utility model relates to a kind of Water pipe heating pipe afterheat boiler system be built on sintering machine flue, belongs to steel smelting equipment technical field.
Background technology
In existing steel making equipment, the belt-cooling machine of sintering machine or the waste gas residual heat of central cooler, generally recycle to produce steam, in order to generate electricity or to use it for anything else.But the waste gas residual heat of sintering machine itself is not yet generally recycled, minority iron and steel enterprise is only had to have employed external (built-in) formula waste-heat recovery device (waste heat boiler, steam generator etc.).As everyone knows, sintering machine after firing, along with pallet is moved from head toward tail, utilizes that the induced draft blower withdraws combustion air on flue is counter to be burnt, and the waste gas after its burning passes into flue via tens pairs of wireways and delivers to chimney by air-introduced machine and discharge.Generally, the waste gas SO2 content of 1# ~ 4# the airduct being in head and 2 ~ 3 airducts being in tail is few, its waste gas does not need desulfurization, directly drain via bottom flue, and the waste gas SO2 content of all the other airducts is more, its waste gas needs desulfurization, then via large flue discharged to deduster and desulfurizer.
As shown in Fig. 1 external waste-heat recovery device, so-called sintering machine external waste-heat recovery device, large flue 2 below sintering machine 1 and bottom flue 3 cut off with electrically operated valve 4,7 respectively, by the waste gas in sintering machine 1 lower tail about 5 wireways via by-pass flue 10,11, valve 5,8 leads to steam superheater 12,14 and steam generator 13,15, then via valve 6,9, by-pass flue 16,17 gets back to flue 2 and flue 3.The steam generator of large and small flue shares 1 drum 18.Operationally, valve-off 4,7, open valve 5,6,8,9, guide the waste gas in about 2 wireways on the waste gas in the wireway of about 3 on large flue 2 and bottom flue 3 into steam superheater 12,14 and steam generator 13,15 respectively, 13,15 vapour produced, aqueous mixtures carry out carbonated drink separation through drum 18, saturated vapor after separation flows through steam superheater 12,14, is heated to temperature required rear outer for generating or outer for it.
The shortcoming that this sintering machine external waste-heat recovery device exists is:
(1) external is arranged and is placed on outside sintering machine main factory building by waste heat boiler, adds floor space, adds device support and platform, pipeline, and for sintering plant, most enterprise does not possess the condition that external is arranged;
(2) by-pass flue increased is difficult to arrange;
(3) add 6 major diameter Flue valves, add equipment investment;
(4) for the waste gas with waste heat recovery value of some other airduct not derivative, can not add up utilization, namely can not accomplish energy cascade utilization, and the temperature of superheated steam can not get reliable guarantee.
Shown in waste-heat recovery device as built-in in Fig. 2, the built-in waste-heat recovery device of so-called sintering machine, large flue 2 below sintering machine 1 is divided into two sections of large flues by superheater and heat pipe evaporator: first flue 2-1 ', second largest flue 2-2 ', first flue 2-1 ' is connected with superheater import, second largest flue 2-2 ' exports with heat pipe evaporator and is connected, bottom flue 3 is divided into two sections of bottom flues by heat pipe evaporator: the first bottom flue 3-1 ', second bottom flue 3-2 ', first bottom flue 3-1 ' is connected with heat pipe evaporator import, second bottom flue 3-2 ' exports with heat pipe evaporator and is connected.Operationally, heat released by the overheated tubular evaparator 5,6 of waste gas streams in about 5 wireways on large bottom flue 2,3, the vapour that heat pipe evaporator 5,6 absorption heat produces, aqueous mixtures carry out carbonated drink separation through drum 7, saturated vapor after separation flows through steam superheater 4, is heated to temperature required rear outer for generating or outer for it.
The shortcoming that the built-in waste-heat recovery device of this sintering machine exists is:
Superheater and heat pipe evaporator directly insert large bottom flue, and operationally, load variations is frequent for sintering machine, are directed at superheater and heat pipe evaporator generation local stress formation leakage, cause parking accident, affect sintering machine and produce.
Operationally, load variations is frequent, and the whole exhaust gas temperature of size flue outlet is uncontrollable, easily makes flue-gas temperature lower than dew-point temperature, affects the service life of the equipment such as air-introduced machine and pipeline for sintering machine.
