The waste heat utilization device 10 comprises a condenser pipe 101, a radiating fin 102, a water delivery hose 103 and a water collection tank 104, wherein the radiating fin 102 is arranged on the condenser pipe 101, two ends of the condenser pipe 101 are respectively connected with the water delivery hose 103 and a steam pipeline, and the water delivery hose 103 is connected with the water collection tank 104. Steam is condensed through the condensing pipe 101, heat is absorbed and dissipated into the pretreatment chamber 1 through the radiating fins 102, and condensed water can be conveyed into the water collecting tank 104 through the water conveying hose 103 for recycling, so that the pretreatment device is more environment-friendly.
Wherein, a flow restriction mechanism 14 for restricting the flow rate of the steam is also arranged in the conduit 12. After the autoclave 2 is depressurized and opened, the steam in the gas storage tank 6 is discharged along with the pressure reduction. If limit the steam velocity of flow through the trompil size, can appear that the trompil is too big, steam runs off fast, and the trompil undersize, steam outflow slow, can't evenly carry out the humidification to aerated concrete plate surface, consequently through current-limiting mechanism 14 automatic control steam velocity of flow, make the even flow portion of steam ability, when prolonging the steam outflow time in the gas storage tank 6 as far as possible, can also guarantee better humidification effect.
The flow limiting mechanism 14 includes an air outlet pipe 1401, a connecting rod 1402, a first baffle 1403 and a second baffle 1404, the air outlet pipe 1401 is disposed in the duct 12, one end of the first baffle 1403 and one end of the second baffle 1404 are respectively hinged in the top end of the air outlet pipe 1401 and the air outlet pipe 1401 one by one, the two ends of the connecting rod 1402 are respectively hinged to the other end of the first baffle 1403 and the other end of the second baffle 1404, and a torsion spring for resetting is disposed at the hinged position of the second baffle 1404. In the normal state, the first blocking plate 1403 covers the top end of the air duct, and the second blocking plate 1404 is vertically downward. When steam flows out, the steam impacts the first baffle 1403 to enable the first baffle 1403 to be turned upwards and opened, the first baffle 1403 rotates, meanwhile, the connecting rod 1402 drives the second baffle 1404 to be turned upwards to limit the steam outlet 16, and the larger the steam flow rate is, the smaller the opening of the second baffle 1404 is. When the steam flow rate is reduced, the second blocking plate 1404 is driven by the torsion spring to turn downwards, the steam outlet 16 is increased, the first blocking plate 1403 is driven by the connecting rod 1402 to turn downwards, the steam still impacts the first blocking plate 1403, and the second blocking plate 1404 cannot be reset by the torsion spring.

Wherein, the inner wall of the air outlet pipe 1401 is provided with a limit block 15 for limiting the turning angle of the second baffle 1404. When the steam impacts the first barrier 1403 to make the first barrier 1403 turn upwards and open, the first barrier 1403 rotates and simultaneously drives the second barrier 1404 to turn upwards through the connecting rod 1402 to limit the outlet of the gas flowing out, and at this time, the steam impacts the second barrier 1404. If the outlet pipe 1401 is in a straight cylindrical shape, it is likely that the second shutter 1404 continues to be turned upwards too much, and the steam outlet is larger, and if the outlet pipe 1401 is in a shape similar to a small top and a large bottom, the problem can be avoided, but the situation that the steam outlet is blocked after the second shutter 1404 is turned over may still occur. In order to prevent the two situations, the limit block 15 limits the turning angle of the second baffle 1404, so that a part of the steam outlet 16 is reserved when the second baffle 1404 is turned to the top.
Wherein, the blast pipe 5 is four, and four blast pipes 5 set up respectively on evaporating foster car 4 four angles, and four blast pipe 5 bottoms all set up pipe 12, and pipe 12 connects exhaust hole 8.
Wherein, a plurality of nozzles 13 are arranged on the side wall of the exhaust pipe 5 from top to bottom. By means of the nozzles 13, steam can be sprayed evenly onto the aerated concrete panels.
Wherein, still include temperature detect switch 17, temperature detect switch 17 sets up in pre-treatment chamber 1, and temperature detect switch 17 connects heating device 11. In order to better control the heating device 11 and reduce the burden on the worker, the heating device 11 can be controlled by the temperature control switch 17.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
