Detailed description of the invention
For further appreciating that present disclosure, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1
In conjunction with Fig. 1 and Fig. 2, slighter compress place steel billet heat radiation residual heat thermoelectric power generation in a kind of iron and steel production of the present embodiment, it is arranged on the slighter compress place that continuous casting produces, steel billet according to this place exposes aerial length, arrange this system to be combined by two temperature difference electricity generation devices, and two temperature difference electricity generation devices are set up in parallel along steel billet discharging direction；Wherein, temperature difference electricity generation device includes bracket institution and heat collection power generation unit 2, bracket institution is erected at above heat radiation steel billet, and heat collection power generation unit 2 is arranged on the outside of bracket institution, is converted into electric energy by the waste heat of 23 steel billet releases of the thermo-electric generation assembly in heat collection power generation unit 2.It is provided with angle-adjusting mechanism 3 bottom bracket institution, is changed the angle of being heated of bracket institution by this angle-adjusting mechanism 3.
Shown in as shown in Figure 1, Figure 2, bracket institution includes top support plate 11 and two pieces of sidewall support plates 12, the two ends of top support plate 11 are hinged with one end of two pieces of sidewall support plates 12 respectively, the other end of sidewall support plate 12 is hinged with the slide block 34 in angle-adjusting mechanism 3, the angle of inclination of sidewall support plate 12 can be adjusted by angle-adjusting mechanism 3, could alter that the position height of top support plate 11 simultaneously.
Top support plate 11 and two pieces of sidewall support plates 12 form semi-closed structure, heat radiation steel billet is surrounded, this heat radiation steel billet can be the billet in steel manufacture process, round steel billet, tubing, bar etc., as long as temperature is at the steel billet of about 550～1200 DEG C, there is bigger heat radiation, all can as thermal energy collecting object, it does not have limit especially.
Heat collection power generation unit 2 in the present embodiment is arranged on top support plate 11 and sidewall support plate 12, specifically as shown in Figure 2, owing in production process, conveying structure is different, only heat collection power generation unit 2 can also be set on top support plate 11 or sidewall support plate 12, the arrangement mode of thermo-electric generation assembly 23 is as shown in Figure 6, Figure 7, determine with specific reference to practical condition, it does not have limit especially.
For the ease of dismounting, top support plate 11 and between on sidewall support plate 12 for removably connecting, it is possible to be use bolt as jointed shaft, back out nut and just can dismantle top support plate 11, it is simple to maintenance conditions.
The main purpose of the angle-adjusting mechanism 3 in the present embodiment is by angle adjustment, as long as ordinary skill may think that the problem that the height that can adjust top support plate 11 and sidewall support plate 12 or width just can reach to adjust heat affected zone, if the adjustment just with this width or height, steel can be made to offset to one end of sidewall support plate 12, the other end of sidewall support plate 12 then can away from steel, although the heating temperature that can make one end is higher, and other end temperature is relatively low, it is heated uneven, generating efficiency is low, it is impossible to enough electric energy that converts heat into fully store.And adopt hinged connected mode can reach to adjust angle to change the purpose of heat affected zone, and overall less by the temperature fluctuation range in heat rating, it is heated evenly.
It is that heated sheet bottom distance steel are relatively near, and temperature is higher, it is necessary to be adjusted for the initial position of sidewall support plate in heated sheet the present embodiment that its principle is referred to Figure 15, a therein；B is the position obtained by angle adjustment, is integrally dispersed in about same temperature gradient scope, and Temperature Distribution is comparatively uniform；C is the position obtained by height adjustment, it is evident that the two ends of heated sheet span three thermogrades, inequality of being heated, has a strong impact on generating efficiency and the service life thereof of thermo-electric generation assembly 23.
