Detailed description of the invention
Describe the structure of flooded evaporator provided by the present invention, principle and work process below in conjunction with the accompanying drawings in detail.
After the molten slag of 1000 ~ 1500 DEG C is granulated by dry method or semidry method granulating device, high temperature slag particle needs further with exhaust-heat absorption device heat exchange to obtain sufficient thermal utilization effect.
As shown in Figures 1 and 2, a kind of flooded evaporator, described device includes the vaporizer tube bank 7 that the evaporator tube group of more than a group, each evaporator tube group include between one group of upper collecting chamber 6a, lower header 6b and upper and lower header.Collection cassette carrier 10 is set below each header.
Described flooded evaporator is arranged on the middle and upper part within waste-heat recovery device 1.Upper collecting chamber 6a, lower header 6b are connected through waste-heat recovery device furnace wall with the drum 5 being located at waste-heat recovery device 1 top with down-comer 9 by tedge 8 respectively, it is achieved steam-water separation and circulation.Vaporizer tube bank 7 is for being obliquely installed, and tilt angle alpha is 5 ~ 45 °.
Different from the header arrangement of conventional heat transfer parts, owing to high-temperature material is the slag particle that hardness is high, upper collecting chamber 6a and lower header 6b is arranged in waste-heat recovery device 1, it is ensured that material flows uniformly through.Meanwhile, upper collecting chamber 6a and lower header 6b is arranged in waste-heat recovery device 1, it is thus also avoided that the unsafe problems that the membrane wall furnace wall that waste-heat recovery device is passed through in numerous vaporizer tube banks 7 brings.Additionally, upper collecting chamber 6a and lower header 6b is little header, the most a diameter of 76mm ~ 273mm.Upper collecting chamber 6a or lower header 6b is often disposed to extend along waste-heat recovery device 1 depth direction.Little header correspondence mini-tube bundle is arranged, and the pipe number of the vaporizer tube bank connected between upper collecting chamber and the lower header on same profile (i.e. parallel with waste-heat recovery device above-below direction cross section) is 3 ~ 7.And a diameter of 38mm ~ 51mm of pipe of described vaporizer tube bank.The set-up mode of little header mini-tube bundle, except ensureing that material flows uniformly through, also further enhances the safety of heat-exchange working medium circulation
In one embodiment, waste-heat recovery device 1 uses moving bed, and the high-temperature material (slag particle etc.) movable feeding gate 3 above moving bed enters inside moving bed.Described feeding gate 3 uses thermal insulation, seals structure, reduces radiation loss.High-temperature material moves in waste-heat recovery device 1 from top to bottom, passes sequentially through flooded evaporator and is positioned at the heat exchanger 2 below flooded evaporator, and then low-temperature material grit chamber 4 bottom waste-heat recovery device 1 discharges.
Described flooded evaporator is generally made up of 3 ~ 5 groups of evaporator tube groups, and each evaporator tube group is arranged in parallel up and down along waste-heat recovery device 1 input and output material direction.And according to heat exchange needs, waste-heat recovery device 1 can arrange two groups and flooded evaporator more than two.
Whole vaporizer is made up of multiple independent evaporator tube groups, it is simple to maintenance, makes technique globality and reliability be further strengthened.
For strengthening the bulk life time of vaporizer, evaporator tube group is positioned at the vaporizer of waste-heat recovery device 1 topmost and restrains 7 tops and arrange abrasion-proof cover plate 11, as shown in Figure 3.Abrasion-proof cover plate 11 is sharp triangle, Y-shaped, bell or class is bell.
