[0041] In practical application, when the autoclaving maintenance of the block is carried out through the steam waste heat recovery and utilization system, the block to be maintained after the static stop stage is first sent to the inside of the main kettle body 101, and a high temperature and high pressure steam gas is introduced to the inside of the kettle body, and between the heating stage and the constant temperature stage, the control heating rate is between 10 ° C and 25 ° C, when the temperature reaches the constant temperature stage, the strength of the concrete block begins to grow rapidly, at this time the control temperature is between 80 ° C and 90 ° C, and ensures that 90% To 100% relative humidity, when the constant temperature phase is completed enters the cooling phase.
[0042] In the process of the cooling stage, because the concrete has hardened, if the cooling rate is too fast, the formation of a large temperature difference of the cooling gradient, will produce a large temperature tensile stress, resulting in cracks in the concrete surface, destroying its concrete structure, at this time in the cooling process, by driving the drive screw 607 deployed on the side of the main kettle body 101 rotation, can drive the drive block 604 on the side of the drive screw 607 between the main kettle body 101 and the liner sleeve 201 directional sliding, And since the drive block 604 slide is assembled in the chute frame 603, so in the process of movement can drive the chute frame 603 between the main kettle body 101 and the liner sleeve 201 to do directional sliding, so as to drive the sliding member 601 on both sides of the slider 601 synchronous sliding, when the sliding member 601 on the side of the chute frame 601 drives towards the side of the drive block 604 When sliding occurs, the slider 601 preferentially and the offset 307 occurs to be offset, And press the offset 307 slides between the main kettle body 101 and the liner sleeve 201, while driving the mobile sleeve 301 to move.
[0043] When the mobile sleeve 301 slides between the main kettle body 101 and the liner sleeve 201, the rotary disc 401 assembled inside the air supply tank 304 is connected to the wall of the liner sleeve 201 during movement, and drives the rotary disk 401 to rotate, when the air guide port 403 on the rotary disc 401 is rotated to the side of the gas guide 304 slot, because the inner sleeve 201 side is connected to the inner cavity of the main kettle body 101 through the air intake tank 202, And the intake chamber 502 is arranged between the lined sleeve 201 and the moving sleeve 301, so when the air conduction port at one end 403 rotates to the side of the intake chamber 502, the high-pressure waste heat vapor contained in the intake chamber 502 flows through the air guide port 403 under pressure and flows towards the side of the exhaust chamber 501, and fills the cavity side of the exhaust chamber 501 under pressure, when the sliding member 601 is reset during the reverse rotation of the driving screw 607, The mobile sleeve 301 reverse reset under the elastic force of one side seal 302 and the elastic member 303, at this time the rotary disc 401 in the moving sleeve 301 rotates in reverse, so that the air conduction port 403 on both sides is resealed, and when the mobile sleeve 301 is reset, the offset member 307 on the side of the mobile sleeve 301 slides to the side of the valve assembly 7, so that the valve assembly 7 is connected to the exhaust cavity body 501, under the pressure of high temperature steam, the gas passes through the gas valve assembly 7 to the outside of the kettle body , variable to the rest of the boost kettle, can also be transported to the flash tank for supersaturated fluid gas-liquid separation, and at this time located on both sides of the sliding member 601 two sets of mobile sleeves 301 in the sliding member 601 reciprocating motion process can achieve alternating waste heat steam output, and in the process of alternating output due to the air flow disturbance driven by exhaust can make the waste heat steam inside the kettle circulate flow, so that the heat in the waste heat vapor is evenly distributed on the block, to ensure stable cooling during the cooling process.
[0044] And the rotary disc 401 in the process of rotation, the air guide port 403 relative to the rotary angle of the air conduction tank 304 is positively correlated with the rotation angle of the rotary disc 401, and the rotation angle of the rotary disk 401 is linearly related to the sliding distance of the moving sleeve 301, so that by controlling the rotation angle of the driving screw 607 can control the sliding distance of the sliding member 601, thereby controlling the sliding distance of the moving sleeve 301, so that the tilt angle of the air guide 403 relative to the gas groove 304 can be controlled It is convenient for precise control of the discharge of waste heat steam, and through a number of synchronous movement of the exhaust member 4, the discharge of waste heat steam can be stable and controllable, so as to achieve stable exhaust in the cooling process.
